    The aim of this study was to examine the effect of an enrichment programme in motor, technical and tactical basketball skills, when accounting for the age of youth sport specialisation. Seventy-six college students (age: M = 20.4, SD = 1.9) were allocated according to three different paths: (i) non-structured (n = 14), (ii) early specialisation (n = 34), and (iii) late specialisation (n = 28), according to information previously provided by the participants about the quantity and type of sporting activities performed throughout their sporting careers. Then, the participants of each path were randomly distributed across control and experimental groups. Variables under study included agility, technical skills circuit, as well as tactical actions performed in a 4-on-4 full-court basketball game. The results indicated improvements in the early and late specialisation paths namely in the experimental training groups. However, the late specialisation path revealed larger benefits, in contrast with the non-structured path, which showed less sensitivity to the enrichment programme, mostly sustained in physical literacy and differential learning. Higher improvements were observed in agility, and also in reducing the number of unsuccessful actions performed during the game. Overall, this study provided evidence of how early sports experiences affect basketball skill acquisition and contribute to adapt to new contexts with motor and technical-tactical challenges. In addition, a path supported by late specialisation might present several advantages in sport performance achievement.

    Athletes who specialize in their sport at an early age may be at risk for burnout, overuse injury, and reduced attainment of elite status. Timing of sport specialization has not been studied in elite basketball athletes. National Basketball Association (NBA) players who played multiple sports during adolescence would be less likely to experience injury and would have higher participation rates in terms of games played and career length compared with single-sport athletes. Descriptive epidemiology study. First-round draft picks from 2008 to 2015 in the NBA were included in the study. From publically available records from the internet, the following data were collected for each athlete: participation in high school sports, major injuries sustained in the NBA, percentage of games played in the NBA, and whether the athlete was still active in the NBA. Athletes who participated in sports in addition to basketball during high school were defined as multisport athletes and were compared with athletes who participated only in basketball in high school. Two hundred thirty-seven athletes were included in the study, of which 36 (15%) were multisport athletes and 201 (85%) were single-sport athletes in high school. The multisport cohort played in a statistically significantly greater percentage of total games (78.4% vs 72.8%; P NBA (94% vs 81.1%; P = .03). While a minority of professional basketball athletes participated in multiple sports in high school, those who were multisport athletes participated in more games, experienced fewer major injuries, and had longer careers than those who participated in a single sport. Further research is needed to determine the reasons behind these differences.

    Team sports are frequently studied by researchers. There is presumption that scoring in basketball is a random process and that can be described using the Poisson Model. Basketball is a collaboration-opposition sport, where the non-linear local interactions among players are reflected in the evolution of the score that ultimately determines the winner. In the NBA, the outcomes of close games are often decided in the last minute, where fouls play a main role. We examined 6130 NBA games in order to analyze the time intervals between baskets and scoring dynamics. Most numbers of baskets (n) over a time interval (ΔT) follow a Poisson distribution, but some (e.g., ΔT = 10 s, n > 3) behave as a Power Law. The Poisson distribution includes most baskets in any game, in most game situations, but in close games in the last minute, the numbers of events are distributed following a Power Law. The number of events can be adjusted by a mixture of two distributions. In close games, both teams try to maintain their advantage solely in order to reach the last minute: a completely different game. For this reason, we propose to use the Poisson model as a reference. The complex dynamics will emerge from the limits of this model.

    Full Text Available The purpose of the study was to determine the efficacy of a 22- week prescribed sports specific balance training programme on the incidence of lateral ankle sprains in basketball players. A controlled clinical trial was set up. In total 54 subjects of six teams participated and were assigned to either an intervention (IG or a control group (CG. The IG performed a prescribed balance training programme on top of their normal training routine, using balance semi-globes. The programme consisted of 4 basketball skills each session and its difficulty was progressively thought-out. The intervention lasted 22 weeks and was performed 3 times a week for 5 to 10 minutes. Efficacy of the intervention on the incidence of lateral ankle sprains was determined by calculating Relative Risks (RR, including their 95% Confidence Intervals or CI and incidence rates expressed per 1000h. RR (95% CI showed a significantly lower incidence of lateral ankle sprains in the IG compared to the CG for the total sample (RR= 0.30 [95% CI: 0.11-0.84] and in men (RR= 0.29 [95% CI: 0.09-0.93]. The difference in RR was not confirmed when examining the incidence rates and their 95%CI's, which overlapped. The risk for new or recurrent ankle sprains was slightly lower in the IG (new: RR= 0.76 [95% CI: 0.17-3.40]; re-injury: RR= 0.21 [95% CI: 0.03-1.44]. Based on these pilot results, the use of balance training is recommended as a routine during basketball activities for the prevention of ankle sprains

    In 2015-2016, over 214,000 female athletes competed at the collegiate level in the United States (U.S.). The National Collegiate Athletic Association (NCAA) collects injury data; however, breast-related injuries do not have a specific reporting category. The exact sequelae of breast injury are unknown; however, a relationship between breast injury and fat necrosis, which mimics breast carcinoma, is documented outside of sports participation. Breast injuries related to motor vehicle collisions, seatbelt trauma, and blunt trauma have been reported. For these reasons, it is important to investigate female breast injuries in collegiate sports. The objectives of this study are to report the prevalence of self-reported breast injuries in female collegiate athletes, explore injury types and treatments, and investigate breast injury reporting and impact on sports participation. A cross-sectional study of female collegiate athletes at four U.S. universities participating in basketball, soccer, softball, or volleyball. Main outcome measure was a questionnaire regarding breast injuries during sports participation. Almost half of the 194 participants (47.9%) reported a breast injury during their collegiate career, less than 10% reported their injury to health personnel with 2.1% receiving treatment. Breast injuries reported by breast injuries reported by sport include softball (59.5%), basketball (48.8%), soccer (46.7%), and volleyball (34.6%). The long-term effects and sequelae of breast injuries reported by female collegiate athletes during sport play are unknown. Nearly 50% of participants had a breast injury during sports activities. Although 18.2% indicated that breast injury affected sports participation, only 9.6% of the injuries were reported to medical personnel with 2.1% receiving treatment.

    We recorded eye movements of eight elite junior basketball players. We hypothesized that a more stable gaze is correlated to a better shot rate. Upon preliminary testing we invited male juniors whose eyes could be reliably tracked in a game situation. To these ends, we used a head-mounted video-based eye tracker. The participants had no record of ocular or other health issues. No significant differences were found between shots made with and without the tracker cap, Paired samples t-test yielded p= .130 for the far and p=..900 > .050 for the middle range shots. The players made 40 shots from common far and middle range locations, 5 and 4 meters respectively for aged 14 years As expected, a statistical correlation was found between gaze fixation (in milliseconds) for the far and middle range shot rates, r=.782, p=.03. Notably, juniors who fixated longer before a shot had a more stable fixation or a lower gaze dispersion (in tracker's screen pixels), r=-.786, p=.02. This finding was augmented by the observation that the gaze dispersion while aiming at the basket was less (i.e., gaze more stable) in those who were more likely to score. We derived a regression equation linking fixation duration to shot success. We advocate infra-red eye tracking as a means to monitor player selection and training success.

    Use of microfracture in the knees of National Basketball Association (NBA) players is controversial. (1) There would be a high rate of return to sport (RTS) in NBA players following microfracture, (2) players would RTS the season following surgery, (3) preoperative player performance would not be significantly different on RTS, and (4) there would be no significant difference in RTS rate or postoperative performance in players undergoing microfracture in comparison with an age-, position-, NBA experience-, and performance-matched control group. Cohort study; Level of evidence, 3. NBA players undergoing microfracture were evaluated. Age-, body mass index-, position-, NBA experience-, and performance-matched controls were selected from the NBA during the same years as those undergoing microfracture. An index year was selected (controls) to match the number of seasons of NBA experience in microfracture cases. RTS and performance were analyzed and compared between cases and controls. Student t tests were performed for analysis of within- and between-group variables. A total of 41 NBA players underwent microfracture and were compared with 41 demographic- and performance-matched controls. Rate of RTS after microfracture was 73% in the NBA and 83% in professional basketball (NBA, D-league, and International Basketball Federation [FIBA]). Time to RTS in NBA was 9.20 ± 4.88 months. Seventy-one percent (29/41) of players RTS the season following microfracture. Length of NBA career following microfracture (4.10 ± 3.91 years) was not significantly different from controls. After microfracture, case athletes played fewer games per season and with fewer points and steals per game (relative to premicrofracture; P NBA players undergoing microfracture returned to professional basketball. Career length was not significantly different between players undergoing microfracture and controls. However, following microfracture, players competed in fewer games per season with fewer points

    Study Design Case report. Background Acute injuries of the triceps surae and Achilles tendon are common in sports. Rupture of the plantaris tendon can be challenging to diagnose. There is limited evidence detailing the diagnosis, rehabilitation, and accelerated return to sport of elite professional basketball players who have sustained calf injuries. Case Description A 25-year-old male professional basketball player sustained an injury to his calf during a professional basketball game. This case report details the presumptive diagnosis, graduated progression of intervention, and return to play of a professional athlete with a likely isolated plantaris tendon tear. Outcomes The patient returned to postseason competition 10 days post injury. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Before returning to play, the athlete showed improvements beyond the minimal clinically important difference for calf girth (2 cm) and numeric pain-rating scale score (4 points, 0-10 scale). Functional testing was conducted that included the Y Balance Test lower quarter and the Functional Movement Screen, with results that exceeded or returned the athlete to preseason levels. Discussion This report details the case of a professional basketball player who returned to competitive play in an accelerated time frame following injury to his calf. Diagnosing a plantaris tendon rupture can be challenging, and anatomical variations of this muscle should be considered. It was demonstrated in this case that physical therapy rehabilitation was helpful in making a treatment-based clinical diagnosis when imaging was unclear. Level of Evidence Therapy, level 5.

    The degree of overall competitiveness of a sport league is a complex phenomenon. It is difficult to assess and quantify all elements that yield the final standing. In this paper, we analyze the general behavior of the result matrices of each season and we use the corresponding results as a probably density. Thus, the results of previous seasons are a way to investigate the probability that each team has to reach a certain number of victories. We developed a model based on Shannon entropy using two extreme competitive structures (a hierarchical structure and a random structure), and applied this model to investigate the competitiveness of two of the best professional basketball leagues: the NBA (USA) and the ACB (Spain). Both leagues’ entropy levels are high (NBA mean 0.983; ACB mean 0.980), indicating high competitiveness, although the entropy of the ACB (from 0.986 to 0.972) demonstrated more seasonal variability than that of the NBA (from 0.985 to 0.990), a possible result of greater sporting gradients in the ACB. The use of this methodology has proven useful for investigating the competitiveness of sports leagues as well as their underlying variability across time.

    Anterior cruciate ligament (ACL) rupture is a significant injury in National Basketball Association (NBA) players. NBA players undergoing ACL reconstruction (ACLR) have high rates of return to sport (RTS), with RTS the season following surgery, no difference in performance between pre- and postsurgery, and no difference in RTS rate or performance between cases (ACLR) and controls (no ACL tear). Case-control. NBA players undergoing ACLR were evaluated. Matched controls for age, body mass index (BMI), position, and NBA experience were selected during the same years as those undergoing ACLR. RTS and performance were compared between cases and controls. Paired-sample Student t tests, chi-square, and linear regression analyses were performed for comparison of within- and between-group variables. Fifty-eight NBA players underwent ACLR while in the NBA. Mean player age was 25.7 ± 3.5 years. Forty percent of ACL tears occurred in the fourth quarter. Fifty players (86%) RTS in the NBA, and 7 players (12%) RTS in the International Basketball Federation (FIBA) or D-league. Ninety-eight percent of players RTS in the NBA the season following ACLR (11.6 ± 4.1 months from injury). Two players (3.1%) required revision ACLR. Career length following ACLR was 4.3 ± 3.4 years. Performance upon RTS following surgery declined significantly (P NBA following ACLR. Nearly all players RTS the season following surgery. Performance significantly declined from preinjury level; however, this was not significantly different from controls. ACL re-tear rate was low. There is a high RTS rate in the NBA after ACLR, with no difference in performance upon RTS compared with controls.

    2014-01-01

    Background Participation in organised youth sports (OYS) has been recommended as an opportunity to increase young peoples’ moderate-to-vigorous physical activity (MVPA) levels. Participants, however, spend a considerable proportion of time during OYS inactive. The purpose of this study, therefore, was to investigate whether coaches who attended coach education sessions (where education on increasing MVPA and decreasing inactivity during training was delivered) can increase players’ MVPA during training sessions over a 5-day basketball program compared to coaches who did not receive coach education sessions. Methods/design A convenience sample of 80 female players and 8 coaches were recruited into the UWS School Holiday Basketball Program in Greater Western Sydney, Australia. A two-arm, parallel-group randomised controlled trial was employed to investigate whether coaches who attended 2 coach education sessions (compared with a no-treatment control) can increase their players’ MVPA during training sessions over a 5-day basketball program. Objectively measured physical activity, directly observed lesson context and leader behaviour, player motivation, players’ perceived autonomy support, and coaching information (regarding training session planning, estimations on player physical activity and lesson context during training, perceived ability to modify training sessions, perceived importance of physical activity during training, intention to increase physical activity/reduce inactivity, and likelihood of increasing physical activity/reducing inactivity) were assessed at baseline (day 1) and at follow-up (day 5). Linear mixed models will be used to analyse between arm differences in changes from baseline to follow-up on all outcomes. Discussion The current trial protocol describes, to our knowledge, the first trial conducted in an OYS context to investigate the efficacy of an intervention, relative to a control, in increasing MVPA. This study’s findings will

    The objective of the present study was to monitor the immunological and hormonal responses and the occurrence of upper respiratory symptoms in adolescent basketball athletes during the different stages of a sports season. Anthropometric measures, biochemical analyses (interleukin-6, interleukin-10, tumour necrosis factor-alpha, C-reactive protein, testosterone and cortisol), neuromuscular evaluations (standing vertical jumping ability, agility and estimated VO2max) and leukocyte counts were performed at four moments: 72 h before the season (-72 h); before the season (Pre-season); after six weeks, at the end of the preparatory period (Preparatory); and after 20 weeks, at the end of the competitive period (Competitive). Also, the occurrence of upper respiratory symptoms was collected weekly during all stages of the season. There were significant increases in monocytes, cortisol, tumour necrosis factor-alpha and C-reactive protein at the Competitive moment as compared to the Pre-season. In addition, interleukin-10 decreased at the Competitive moment as compared to the Pre-season. Occurrence of upper respiratory symptoms demonstrated increases (38%) during the competitive period as compared to the preparatory. These results suggest that periods of training and competition could increase the occurrence of upper respiratory symptoms in adolescent athletes and this may be due to the unwanted effects of an inflammatory process in response to the excessive stress of training and competition.

  19. Monitoring and Managing Fatigue in Basketball

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available The sport of basketball exposes athletes to frequent high intensity movements including sprinting, jumping, accelerations, decelerations and changes of direction during training and competition which can lead to acute and accumulated chronic fatigue. Fatigue may affect the ability of the athlete to perform over the course of a lengthy season. The ability of practitioners to quantify the workload and subsequent fatigue in basketball athletes in order to monitor and manage fatigue levels may be beneficial in maintaining high levels of performance and preventing unfavorable physical and physiological training adaptations. There is currently limited research quantifying training or competition workload outside of time motion analysis in basketball. In addition, systematic research investigating methods to monitor and manage athlete fatigue in basketball throughout a season is scarce. To effectively optimize and maintain peak training and playing performance throughout a basketball season, potential workload and fatigue monitoring strategies need to be discussed.

    Full Text Available Data on the physical and performance characteristics of female wheelchair basketball (WB players are scarce. In several countries female WB players train and compete with male players on mixed teams due to the limited total population of players, which would otherwise lead to large territorial spread for each team. Any differences in terms of physical characteristics and/or WB skill proficiency between male and female WB players would be relevant to team performance in mixed teams. This work examined anthropometry, body composition, and performance in a set of sport-specific field tests in a sample of 13 female WB players representing about 40% of the eligible population in Italy across a range of functional point scores (Point. Point is assigned on an ordinal scale from 1.0 (i.e., players with minimal functional potential through to 4.5 (players with maximum functional potential.

    We examined the influence of visual context information on skilled motor behaviour and motor adaptation in basketball. The rules of basketball in Europe have recently changed, such that that the distance for three-point shots increased from 6.25 m to 6.75 m. As such, we tested the extent to which basketball experts can adapt to the longer distance when a) only the unfamiliar, new three-point line was provided as floor markings (NL group), or b) the familiar, old three-point line was provided in addition to the new floor markings (OL group). In the present study 20 expert basketball players performed 40 three-point shots from 6.25 m and 40 shots from 6.75 m. We assessed the percentage of hits and analysed the landing position of the ball. Results showed better adaptation of throwing performance to the longer distance when the old three-point line was provided as a visual landmark, compared to when only the new three-point line was provided. We hypothesise that the three-point line delivered relevant information needed to successfully adapt to the greater distance in the OL group, whereas it disturbed performance and ability to adapt in the NL group. The importance of visual landmarks on motor adaptation in basketball throwing is discussed relative to the influence of other information sources (i.e. angle of elevation relative to the basket) and sport practice.

    Study Design Case report. Background Acute traumatic avulsion of the rectus abdominis and adductor longus is rare. Chronic groin injuries, often falling under the athletic pubalgia spectrum, have been reported to be more common. There is limited evidence detailing the comprehensive rehabilitation and return to sport of an athlete following surgical or conservative treatment of avulsion injuries of the pubis or other sports-related groin pathologies. Case Description A 29-year-old National Basketball Association player sustained a contact injury during a professional basketball game. This case report describes a unique clinical situation specific to professional sport, in which a surgical repair of an avulsed rectus abdominis and adductor longus was combined with a multimodal impairment- and outcomes-based rehabilitation program. Outcomes The patient returned to in-season competition at 5 weeks postoperation. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Measures such as the Copenhagen Hip and Groin Outcome Score and numeric pain-rating scale revealed progress beyond the minimal important difference. Discussion This case report details the clinical reasoning and evidence-informed interventions involved in the return to elite sport. Detailed programming and objective assessment may assist in achieving desired outcomes ahead of previously established timelines. Level of Evidence Therapy, level 4.

Traditional vs. sport-specific vertical jump tests: reliability, validity, and relationship with the legs strength and sprint performance in adult and teen soccer and basketball players. J Strength Cond Res 31(1): 196-206, 2017-The vertical jump is considered an essential motor skill in many team sports. Many protocols have been used to assess vertical jump ability. However, controversy regarding test selection still exists based on the reliability and specificity of the tests. The main aim of this study was to analyze the reliability and validity of 2 standardized (countermovement jump [CMJ] and Abalakov jump [AJ]) and 2 sport-specific (run-up with 2 [2-LEGS] or 1 leg [1-LEG] take-off jump) vertical jump tests, and their usefulness as predictors of sprint and strength performance for soccer (n = 127) and basketball (n = 59) players in 3 different categories (Under-15, Under-18, and Adults). Three attempts for each of the 4 jump tests were recorded. Twenty-meter sprint time and estimated 1 repetition maximum in full squat were also evaluated. All jump tests showed high intraclass correlation coefficients (0.969-0.995) and low coefficients of variation (1.54-4.82%), although 1-LEG was the jump test with the lowest absolute and relative reliability. All selected jump tests were significantly correlated (r = 0.580-0.983). Factor analysis resulted in the extraction of one principal component, which explained 82.90-95.79% of the variance of all jump tests. The 1-LEG test showed the lowest associations with sprint and strength performance. The results of this study suggest that CMJ and AJ are the most reliable tests for the estimation of explosive force in soccer and basketball players in different age categories.

    This literature review evaluates the significance of dental injuries and their relationship to a specific sport--basketball. Many studies have been published on individual sports or groups of sports, but most pertain to specific age groups or levels of competition. Research suggests that many sports that do not require mouthguards should encourage male and female participants to use orofacial protectors. Athletes, coaches, athletic directors, athletic trainers, parents, and members of the dental community should be aware of how individuals who participate in sporting activities are at risk for dental trauma. Any sport where the potential for dental trauma can exist, such as basketball, soccer, or wrestling, should consider utilizing mouthguards to protect the competitors. The establishment of mouthguard programs for athletes of all ages and genders who participate in basketball may help to reduce the incidence of dental trauma.

    The influence of maturity status on body size, functional capacities and basketball-specific skills was evaluated and multivariate relationships between domains of variables were examined in 80 male basketball players 12.0-13.9 years. Height, body mass and two skinfolds were measured. Stage of pubic hair (PH) was assessed clinically. Functional capacity was assessed with the vertical jump (squat jump, countermovement jump), 2-kg medicine ball throw, hand grip strength, 60-second sit-ups and endurance shuttle run. Performances on four basketball skills were tested: shooting, passing, dribbling and defensive movements. Analysis of covariance with age as the covariate was used to test differences among players by stage of puberty. Associations among body size, adiposity, functional capacities and skills were evaluated with canonical correlation analysis. Maturity status explained a significant portion of variance in body size (F=50.13, Pjumps and upper limb strength, but not for sit-ups or aerobic endurance. Canonical correlations showed an inverse relationship of height and adiposity with skill tests, and a positive relationship between skills and a combination of abdominal muscular strength (sit-ups) and aerobic endurance. Skill appeared to be independent of pubertal status and the tallest group of basketball players did not attain better scores in basketball-specific skill tests.

    Female athletes have a higher risk of anterior cruciate ligament injury than their male counterparts who play at similar levels in sports involving pivoting and landing. The competitive female basketball players who participated in a sports injury prevention training program would show better muscle strength and flexibility and improved biomechanical properties associated with anterior cruciate ligament injury than during the pretraining period and than posttraining parameters in a control group. Controlled laboratory study. A total of 22 high school female basketball players were recruited and randomly divided into 2 groups (the experimental group and the control group, 11 participants each). The experimental group was instructed in the 6 parts of the sports injury prevention training program and performed it during the first 20 minutes of team practice for the next 8 weeks, while the control group performed their regular training program. Both groups were tested with a rebound-jump task before and after the 8-week period. A total of 21 reflective markers were placed in preassigned positions. In this controlled laboratory study, a 2-way analysis of variance (2 x 2) experimental design was used for the statistical analysis (P training effects on all strength parameters (P = .004 to .043) and on knee flexion, which reflects increased flexibility (P = .022). The experimental group showed higher knee flexion angles (P = .024), greater interknee distances (P = .004), lower hamstring-quadriceps ratios (P = .023), and lower maximum knee extension torques (P = .043) after training. In the control group, no statistical differences were observed between pretraining and posttraining findings (P = .084 to .873). At pretraining, no significant differences were observed between the 2 groups for any parameter (P = .067 to .784). However, a comparison of the 2 groups after training revealed that the experimental group had significantly higher knee flexion angles (P = .023

    Anterior cruciate ligament injury prevention programs are less successful in basketball than soccer and may be due to distinct movement strategies that these athletes develop from sport-specific training. The purpose of this study was to identify biomechanical differences between female basketball and soccer players during multi-directional jump landings. Lower extremity biomechanics of eighty-nine female athletes who played competitive basketball (n=40) or soccer (n=49) at the middle- or high-school level were analyzed with three-dimensional motion analysis during a drop vertical jump (DVJ), double- (SAG-DL) and single-leg forward jump (SAG-SL), and double- (FRONT-DL) and single-leg (FRONT-SL) lateral jump. Basketball players landed with less hip and/or knee excursion during all tasks (pbasketball players landed with greater peak hip flexion angles (p=.04). The FRONT-SL task elicited the most distinct sport-specific differences, including decreased hip adduction (pbasketball players. Additionally, the FRONT-SL task elicited greater forces in knee abduction (p=.003) and lesser forces in hip adduction (p=.001) and knee external rotation (pbasketball players. Joint energetics were different during the FRONT-DL task, as basketball players exhibited less sagittal plane energy absorption at the hip (pjump landing tasks, such that soccer players exhibited a more protective landing strategy than basketball players, justifying future efforts toward sport-specific ACL injury prevention programs.

    Background ACL injury prevention programs are less successful in female basketball players than in soccer players. Previous authors have identified anthropometric and biomechanical differences between the athletes and different sport‐specific demands, including a higher frequency of frontal plane activities in basketball. Current injury risk screening and preventive training practices do not place a strong emphasis on frontal plane activities. The medial and lateral triple hop for distance tests may be beneficial for use in the basketball population. Hypothesis/Purpose To 1) establish normative values for the medial and lateral triple hop tests in healthy female collegiate athletes, and 2) analyze differences in test scores between female basketball and soccer players. It was hypothesized that due to the frequent frontal plane demands of their sport, basketball players would exhibit greater performance during these frontal plane performance tests. Study Design Cross‐sectional. Methods Thirty‐two NCAA Division‐1 female athletes (20 soccer, 12 basketball) performed three trials each of a medial and lateral triple hop for distance test. Distances were normalized to height and mass in order to account for anthropometric differences. Repeated measures ANOVAs were performed to identify statistically significant main effects of sport (basketball vs. soccer), and side (right vs. left), and sport x side interactions. Results After accounting for anthropometric differences, soccer players exhibited significantly better performance than basketball players in the medial and lateral triple hop tests (p jumped farther on their left (400.3 ± 41.5 cm) than right (387.9 ± 43.4 cm) limbs, but no side differences were identified in the lateral triple hop. No significant side x sport interactions were identified. Conclusions Women's basketball players exhibit decreased performance of frontal plane hop tests when compared to women's soccer players.

    The volume of literature on fitness testing in court sports such as basketball is considerably less than for field sports or individual sports such as running and cycling. Team sport performance is dependent upon a diverse range of qualities including size, fitness, sport-specific skills, team tactics, and psychological attributes. The game of basketball has evolved to have a high priority on body size and physical fitness by coaches and players. A player's size has a large influence on the position in the team, while the high-intensity, intermittent nature of the physical demands requires players to have a high level of fitness. Basketball coaches and sport scientists often use a battery of sport-specific physical tests to evaluate body size and composition, and aerobic fitness and power. This testing may be used to track changes within athletes over time to evaluate the effectiveness of training programmes or screen players for selection. Sports science research is establishing typical (or 'reference') values for both within-athlete changes and between-athlete differences. Newer statistical approaches such as magnitude-based inferences have emerged that are providing more meaningful interpretation of fitness testing results in the field for coaches and athletes. Careful selection and implementation of tests, and more pertinent interpretation of data, will enhance the value of fitness testing in high-level basketball programmes. This article presents reference values of fitness and body size in basketball players, and identifies practical methods of interpreting changes within players and differences between players beyond the null-hypothesis.

The research was conducted with the aim to determine the specifics of motor abilities in basketball players of the junior rank of competition. All the examinees were male, 16 (+/-6 months years old, 132 in total, all of them were basketball players of the basketball club ”Student” from Nis. The batery of tests for the evaluation of motor abilities included tests for the evaluation of coordination, strength (explosive, repetitive and static, flexibility and stamina and it consisted of 13 motor tests in total. The gained results were processed by the program system for multivariant analysis of data, especially made by Popovic D. for personal computers. The gained results are shown in tables and they give insight into the structure of latent dimensions of basketball players. The motor structure of basketball players is explained by 72.3% of common variance. From the matrix of intercorrelations, four main components were gained. The fist defines tests of static strength, flexibility and repetitive strength; the second is saturated by the test for the evaluation of explosive strength, balance and two tests for the evaluation of repetitive strength. The third is the best explained by the test for the evaluation of balance, flexibility and coordination. The fourth main component is defined by explosive strength. Then, the rotation of components into the oblimin solution is conducted and some better structure of latent dimensions is gained that way. In basketball and other popular sports games in our country, scientific and expert methods and possibilities of scientific fundation of the trainig work are very slowly but surely accepted.The trend

    Full Text Available ABSTRACT Traumatic brain injury (TBI is a major cause of lifelong disability and death worldwide. Sport-related traumatic brain injury is an important public health concern. The purpose of this review was to highlight the importance of sport-related concussions. Concussion refers to a transient alteration in consciousness induced by external biomechanical forces transmitted directly or indirectly to the brain. It is a common, although most likely underreported, condition. Contact sports such as American football, rugby, soccer, boxing, basketball and hockey are associated with a relatively high prevalence of concussion. Various factors may be associated with a greater risk of sport-related concussion, such as age, sex, sport played, level of sport played and equipment used. Physical complaints (headache, fatigue, dizziness, behavioral changes (depression, anxiety, irritability and cognitive impairment are very common after a concussion. The risk of premature return to activities includes the prolongation of post-concussive symptoms and increased risk of concussion recurrence.

    The purpose of this study was to examine and compare the cardiorespiratory performance and isokinetic muscle strength between Greek soccer and basketball players of different divisions before starting the training season. Study participants included 100 soccer players and 61 basketball players, who were assigned according to the kind of sport and division. All participants underwent anthropometric measurements and performed an exercise test on a treadmill to determine maximal oxygen uptake (VO2max). Peak torque for quadriceps and hamstring muscles was measured on isokinetic dynamometer at angular velocity of 60 degrees/s(-1), 180 degrees/s(-1), and 300 degrees/s(-1). The statistical p value was set at p duration of the maintenance period and to the effect of the training session on each sport, respectively. Finally, a higher level of muscle strength would be preferable in soccer and basketball and would reduce the risk for injuries in the maintenance and rebuilding training periods.

    Stretching is often included as part of a warm-up procedure for basketball activity. However, the efficacy of stretching with respect to sport performance has come into question. We determined the effects of 4 different warm-up protocols followed by 20 minutes of basketball activity on flexibility and vertical jump height. Subjects participated in 6 weeks (2 times per week) of warm-up and basketball activity. The warm-up groups participated in ballistic stretching, static stretching, sprinting, or basketball shooting (control group). We asked 3 questions. First, what effect does 6 weeks of warm-up exercise and basketball play have on both flexibility and vertical jump height? We measured sit and reach and vertical jump height before (week -1) and after (week 7) the 6 weeks. Flexibility increased for the ballistic, static, and sprint groups compared to the control group (p vertical jump height did not change for any of the groups. Our second question was what is the acute effect of each warm-up on vertical jump height? We measured vertical jump immediately after the warm-up on 4 separate occasions during the 6 weeks (at weeks 0, 2, 4, and 6). Vertical jump height was not different for any group. Finally, our third question was what is the acute effect of each warm-up on vertical jump height following 20 minutes of basketball play? We measured vertical jump height immediately following 20 minutes of basketball play at weeks 0, 2, 4, and 6. Only the ballistic stretching group demonstrated an acute increase in vertical jump 20 minutes after basketball play (p basketball play, as it is beneficial to vertical jump performance.

Wheelchair basketball players (n = 111) and non-player (n = 85) were included in this study. We administered the questionnaire version of the wheelchair skills test questionnaire (WST_Q), recording the participants' capacity and performance scores on each of 32 skills. Player group have the baseline values of WST_Q higher than control group. The mean total percentage score of player group was significantly greater than control group (p skills-sports relationship is reciprocal. With increased wheelchair skills, people may be more inclined to engage in sports; subsequently, with greater sports, wheelchair skills could improve. Wheelchair mobility skills during clinical rehabilitation should reflect the daily activities and needs of each wheelchair user. WST-Q provides advantages in terms of requiring less time and material in using of clinical.

    OBJECTIVE--To determine the acute injury profile in each of six sports and compare the injury rates between the sports. DESIGN--Analysis of national sports injury insurance registry data. SETTING--Finland during 1987-91. SUBJECTS--621,691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate. MAIN OUTCOME MEASURES--Acute sports injuries requiring medical treatment and reported to the insurance company on structured forms by the patients and their doctors. RESULTS--54,186 sports injuries were recorded. Injury rates were low in athletes aged under 15, while 20-24 year olds had the highest rates. Differences in injury rates between the sports were minor in this adult age group. Overall injury rates were higher in sports entailing more frequent and powerful body contact. Each sport had a specific injury profile. Fractures and dental injuries were most common in ice hockey and karate and least frequent in volleyball. Knee injuries were the most common cause of permanent disability. CONCLUSIONS--Based on the defined injury profiles in the different sports it is recommended that sports specific preventive measures should be employed to decrease the number of violent contacts between athletes, including improved game rules supported by careful refereeing. To prevent dental injuries the wearing of mouth guards should be encouraged, especially in ice hockey, karate, and basketball. PMID:8520333

    Basketball is a popular, worldwide sport played outdoors and indoors year-round. Patterns of injury are related to abrupt changes in the athlete's direction, jumping, contact between athletes, the hard playing surface and paucity of protective equipment. Intensity of play and training in the quest of scholarships and professional careers is believed to contribute to an increasing occurrence of injury. Radiologists' appreciation of the breadth of injury and its relation to imaging and clinical findings should enhance the care of these children. Some of the patterns of injury are well known to radiologists but vary due to age- and size-related changes; the growing skeleton is affected by differing susceptibilities from biomechanical stresses at different sizes. Beyond screening radiographs, the accuracy of MRI and CT has improved diagnosis and treatment plans in this realm. Investigations to detect symptoms and signs in an attempt to prevent the tragedy of sudden cardiac death in basketball players may lead to MRI and CTA studies that compel radiologists to evaluate cardiac function along with myocardial and coronary artery anatomy. Worthy of mention also is the female athlete triad of disordered eating, amenorrhea, and osteoporosis that is observed in some young women participating in this and other sports. (orig.)

    Poor knee alignment is associated with increased loading of the joints, ligaments and tendons, and may increase the risk of injury. The study purpose was to compare differences in knee kinematics between basketball and floorball players during a vertical drop jump (VDJ) task. We wanted to investigate whether basketball players, whose sport includes frequent jump-landings, exhibited better knee control compared with floorball players, whose sport involves less jumping. Complete data was obtained from 173 basketball and 141 floorball players. Peak knee valgus and flexion angles during the VDJ were analyzed by 3D motion analysis.Larger knee valgus angles were observed among basketball players (- 3.2°, 95%CI -4.5 to - 2.0) compared with floorball players (- 0.9°, 95%CI -2.3 to 0.6) (P=0.022). Basketball players landed with a decreased peak knee flexion angle (83.1°, 95%CI 81.4 to 84.8) compared with floorball players (86.5°, 95%CI 84.6 to 88.4) (P=0.016). There were no significant differences in height, weight or BMI between basketball and floorball players. Female athletes exhibited significantly greater valgus angles than males. This study revealed that proper knee control during jump-landing does not seem to develop in young athletes simply by playing the sport, despite the fact that jump-landings occur frequently in practice and games. © Georg Thieme Verlag KG Stuttgart · New York.

    The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketball. Variance components models derived from series of multilevel linear regression models revealed a substantial variation by maturity status for body size, functional capacities indicators, mastery and will to excel. The influence of estimated maturity status on mastery and will to excel was independent of age and years of experience. In contrast, no relationships were observed between psychological variables and functional capacities indicators. We conclude that growth-related changes are relevant to understanding players´ motivations for achievement, competitiveness and deliberate practice. This should be of interest to those involved in the selection and development of youth basketball players.

    Full Text Available Basketball is in the top of favourite sports. The appearance of private sport clubs on the sports market is caused by the increasingly precarious conditions in state institutions and, at the same time, by the influence of the European Community. We aim at identifying a pattern of activity meant to attract and educated children in the field of basketball through private basketball clubs by making parents aware of the beneficial effects of basketball and of being a member of a sports team. The survey was carried out in 12 private basketball clubs that carry out activities in a consequent manner (in number and in value. Private basketball club managers responded to the questions in our questionnaire showing willingness to cooperate; results show that all private basketball clubs are non-profit organisations and are involved in the competitions organised by the Romanian Federation of Basketball. Private basketball clubs represent half of the affiliated basketball clubs and dominate the competitions reserved to the different age categories, which denotes the efficiency of their activities.

    Full Text Available This article presents part of the research performed within the scope of the national project “Conceptual Metaphors in Public Discourse,”1 financed by the Research Council of Lithuania. The aim of the present paper is to analyze conceptual metaphors in the discourse of the European Basketball Championship which took place in Kaunas, Lithuania in 2011, as well as to determine the source concepts. The analysis allows certain features of the images which are used while conceptualizing the entities related to basketball to be described. The metaphorical collocations drawn from the Lithuanian language corpora and web portals (www.delfi.lt and www.lrytas.lt were selected and analyzed from 31 August 2011 to 18 September 2011. A conceptual metaphor is defined as an interaction of two conceptual fields (source and target concepts. On the basis of the analyzed conceptual sayings, the reconstructed conceptual metaphors proved that the most prolific metaphors are of war, ontology, and scale. In basketball discourse, the war metaphor is characterized by the fact that the image of sport is war is supplemented by other source concepts (e.g.,a person, a building, a thing, a material, a scale. The features of two or sometimes even three source concepts are ascribed to the target concept.

    The ability to shoot an effective jump shot in the sport of basketball is critical to a player's success. In an attempt to better understand the aspects related to expert performance, researchers have investigated successful free throws and jump shots of various basketball players and identified movement variables that contribute to their success. The purpose of this study was to complete a systematic review of the scientific literature on the basketball free throw and jump shot for the purpose of revealing the critical components of shooting that coaches, teachers, and players should focus on when teaching, learning, practising, and performing a jump shot. The results of this review are presented in three sections: (a) variables that affect ball trajectory, (b) phases of the jump shot, and (c) additional variables that influence shooting.

    Full Text Available Despite the acknowledged importance of fatigue on performance in sport, ecologically sound studies investigating fatigue and its effects on sport-specific skills are surprisingly rare. The aim of this study was to investigate the effect of moderate and high intensity total body fatigue on passing accuracy in expert and novice basketball players. Ten novice basketball players (age: 23.30 ± 1.05 yrs and ten expert basketball players (age: 22.50 ± 0.41 yrs volunteered to participate in the study. Both groups performed the modified AAHPERD Basketball Passing Test under three different testing conditions: rest, moderate intensity and high intensity total body fatigue. Fatigue intensity was established using a percentage of the maximal number of squat thrusts performed by the participant in one minute. ANOVA with repeated measures revealed a significant (F 2,36 = 5.252, p = 0.01 level of fatigue by level of skill interaction. On examination of the mean scores it is clear that following high intensity total body fatigue there is a significant detriment in the passing performance of both novice and expert basketball players when compared to their resting scores. Fundamentally however, the detrimental impact of fatigue on passing performance is not as steep in the expert players compared to the novice players. The results suggest that expert or skilled players are better able to cope with both moderate and high intensity fatigue conditions and maintain a higher level of performance when compared to novice players. The findings of this research therefore, suggest the need for trainers and conditioning coaches in basketball to include moderate, but particularly high intensity exercise into their skills sessions. This specific training may enable players at all levels of the game to better cope with the demands of the game on court and maintain a higher standard of play

    In sports, such as basketball and volleyball, players must demonstrate the speed, strength, stamina and concentration. Correct nutrition affects the strength of the muscles and the extension of capacity. It is also necessary for the proper functioning of the nervous system and determines the rate of regeneration after physical effort. The aim of this study was to assess dietary behaviours of professional volleyball and basketball players and compare the prevalence of correct behaviours in both groups. 209 professional volleyball and basketball players from sports clubs localized in six Silesian cities were survived with the mean of author questionnaire. The chi-square test was used to examine differences in the prevalence of the correct behaviours among players. Analysis of the results obtained showed that 52% of the players had 4-5 meals a day. 35% of respondents had wholemeal bread and/or groats daily. Milk and dairy products daily ate 71% of surveyed players, meat and sausages 70% respectively. 41% of respondents had cottage cheese and 28% had fish several times a week. Vegetables and fruit were eaten by 21% and respectively 23% of respondents. Sweets were eaten daily by 40% of surveyed, while fast-food were eaten several times a week by 17% of players. Nutrients for athletes were used by 32%, and vitamin supplementation by 48% of respondents. Prevalence of correct dietary behaviour in the group of professional volleyball and basketball players differed. Basketball players statistically more frequently than volleyball players had 4-5 meals a day, had wholemeal bread and/or thick groats, milk and dairy products, meat and sausages, especially poultry. They had raw vegetables and fruit several times a day. They drank more than 2.5 liters of fluids per day. They also significantly more frequently than volleyball players consumed the fast-food occasionally or never. Dietary behaviours of surveyed players were incorrect.

    Full Text Available The model of modern sports performance asks for certain graduation in the treatment of its efficiency. Besides the coaching model, what matters is the genetic potential of the child or junior, and particularly the selection of the young talented athlete identified at the proper time and included in a proper training system, in full harmony with the education process. The sports output is determined by the simultaneous action of several factors whose influences are different. At present, there is a tendency to improve those factors on which rely sports outcomes and that need to be analysed and selected. Psychic capacity is a major factor, and mental control – the power to focus, motor intelligence, motor memory, creativity, and tactical skills play a major role in an athlete’s style. This study aims at showing the measure in which motor memory allows early and reliable diagnosis of future performance. The subjects selected are components of the mini-basket team of the Sports Club “Sport Star” from Timisoara, little girls that have played basketball since 1st grade in their free time (some of the girls have played it for four years. The research was carried out during a competitive year; we monitored the subjects both during coach lessons and minibasketball championship. To assess motor memory, we used the “cerebral module” consisting in memorising a complex of technical and tactical elements and applying them depending on the situation in the field. The research also involved monitoring the subjects in four directions considered defining in the assessment of the young athletes: somatic data, physical features, basketball features and intellectual potential. Most parameters point out a medium homogeneity of the group, except for height and commitment (great homogeneity. Half of the athletes of the tested group are above the mean of the group, which allows guiding them towards higher coaching forms (allowing them to practice basketball

    Women's basketball has changed over time. It is a faster paced game than it was 30 years ago. Greatplayers, like Anne Meyers,who was the first, and only, woman to be signed to an NBA contract, would agree today's game is different. The game is played mostly "below the rim" but with players like Candice Parker, Sylvia Fowles and Maya Moore able to dunk the ball, the game is still changing. The one thing that remains constant in basketball, especially women's basketball, is injury. The majority of injuries in women's basketball are similar to those in men's basketball. Studies at the high school and college level show similar injury rates between women and men. ACL injuries are one exception, with female athletes having atwo to four times higher rate ofACL injuries. In this article, we review the common injuries in women's basketball. We discuss treatment issues and possible preventive measures.

    Our study examined whether the introduction of a smaller and lighter basketball (no. 6) affected the accuracy of female basketball players’ shots at the basket. The International Basketball Federation (FIBA) introduced a size 6 ball in the 2004/2005 season to improve the efficiency and accuracy of technical elements, primarily shots at the basket. The sample for this study included 573 European female basketball players who were members of national teams that had qualified for the senior women’s European championships in 2001, 2003, 2005 and 2007. A size 7 (larger and heavier) basketball was used by 286 players in 1,870 matches, and a size 6 basketball was used by 287 players in 1,966 matches. The players were categorised into three playing positions: guards, forwards and centres. The results revealed that statistically significant changes by year occurred only in terms of the percentage of successful free throws. With the size 6 basketball, this percentage decreased. Statistically significant differences between the playing positions were observed in terms of the percentage of field goals worth three points (between guards and forwards) and two points (between guards and centres). The results show that the introduction of the size 6 basketball did not lead to improvement in shooting accuracy (the opposite was found for free throws), although the number of three-point shots increased.

    Basketball is a physical game played on a hardwood floor among high-jumping athletes at risk for injury. It is currently unknown how sport-related concussion (SRC) affects player performance after injury among professional basketball players. The objective of this study was to explore the impact of SRC on basketball performance among National Basketball Association (NBA) players. A retrospective, archival cohort study was performed that compared NBA player performance following concussion to pre-concussive performance. A comprehensive NBA injury database, compiled from publically available sources, was queried for NBA players who suffered concussion from 2005-06 to 2014-15 (10 seasons). Intra-and inter-player analyses were performed against a matched control group of players who missed playing time for personal reasons. Following application of inclusion/exclusion criteria and a matching process, 51 concussed players and 51 control players were included in analysis. There were no statistically significant decrements in baseline to post-concussion performance metrics in intra-player or player vs. controls after 5 return games. Our findings suggest that at the NBA level, an athlete's performance in the initial 5 games following injury does not suffer from the after-effects of concussive injury. These results may be useful in counseling professional athletes following a concussion.

    2010-05-01

    The main purpose of this article was to review a series of studies (n=26; 15 observational and 11 experimental) examining vertical jump (VJ) performances in female and male basketball players. Information on the tests used in these studies and their specific protocols, and the training programs conducted to improve VJ ability in elite basketball players, was assessed. It was found that vertical jump values varied greatly, from 22 to 48 cm in female players and from 40 to 75 cm in male players. These large variations can be explained mostly by the differences in testing protocols (each VJ protocol examined different physiological pathways) and skill level of players. The variations in VJ values among studies were greatly reduced when they used the same protocol. In addition, short plyometric training sessions as part of the strength and conditioning program were found to enhance VJ performances in basketball players. Based on the reviewed studies, five limitations associated with the testing protocols and the strength and conditioning programs used in the studies were outlined, among them the use of multiple testing protocols and lack of experimental studies. Three recommendations for basketball and strength and conditioning coaches were suggested, for one of which was including plyometric training in the annual training program. 2009 Sports Medicine Australia.

Genotype distributions did not differ between groups (cases: 37.0% [RR], 42.0% [RX], and 21.0% [XX]; controls: 31.8% [RR], 49.8% [RX], and 18.4% [XX]; P = .353). The authors did not observe any effect of the ACTN3 R577X polymorphism on study phenotypes in either group, including when they performed the analyses separately in men and women. They found no association between the ACTN3 R577X polymorphism and the likelihood of being an elite basketball player using the dominant or the recessive model, and the results remained unaltered when the analyses were adjusted for sex, weight, height, and age or when performed for men and women separately. Although the ACTN3 R577X is associated with explosive muscle performance and this phenotype is important in the sport of basketball (ie, during jumps), the authors found no association with leg explosive power in elite basket players or with the status of being this type of athlete.

    The purpose of the present study was to investigate the relationships between general coordination, sport-specific coordination, and sport-specific fitness of 8- to 17-year-old male basketball players. 312 males with training experience ranging from one year in the 8-year-old cohort up to 10 years for the 17-year-olds performed basketball-specific fitness (20 m sprint, Illinois, countermovement jump), general coordination (20 m run with three obstacles), semi-basketball-specific coordination (20 m sprint dribbling two balls, countermovement jump with arm swing) and basketball-specific coordination (Illinois ball dribbling) tests. There were moderate to large correlations between the results of both general and basketball-specific coordination with the results of most basketball-specific coordination tests in all age groups. Correlations between general and basketball-specific coordination were large in four age groups (11-14 yr., r = .52 to r = .76), moderate in five groups (8-10, 15 & 16 yr., r = .37 to r = .46), while not significant in the 17-year-olds. These results suggest that the importance of general coordination for sport-specific skills improvements during a sports-specific skill acquisition phase, remains high at the skill refinement phase, and decreases when sport-specific skills have been mastered to near-perfection.

    Numerous foundational movements performed during basketball are predicated on underlying power-related attributes, including speed, change-of-direction, and jumping. Accordingly, fitness testing batteries for basketball have incorporated an assortment of linear speed tests, change-of-direction tests, and jump tests. However, due to the wide variety of testing options it is difficult for basketball practitioners to select appropriate testing protocols for the assessment of power-related attributes. As a result, there is a need to review the relevant literature to identify game-specific, power-related attributes important in basketball and the most appropriate tests available to assess power-related attributes for basketball practitioners. Therefore, the aims of this review were to: (1) identify essential power-related attributes important in basketball; (2) discuss the suitability of common and novel power-related tests; and (3) provide recommendations for future research and best practice approaches for basketball coaching staff. In this review, we propose a series of novel tests that are more targeted and specific to basketball movements including: (1) 5-m and 10-m linear sprints, (2) Modified Agility T-Test, (3) Change-of-Direction Deficit, (4) lateral bound, (5) Sargent jump, (6) one-step jump, and (7) isometric midthigh pull test. Improved testing of power-related attributes should enable basketball practitioners to develop targeted training plans for enhancing player performance.

    The XXI Century Academy was a 6-year state-initiated intervention program that served as an alternative to basketball clubs for players in the u-14 and u-18 age groups in Spain, under guidelines established by the Spanish Basketball Federation. It was an important and unique project on talent development in basketball. To the best of the authors' knowledge, no evidence has been reported on long-term athlete development programs in basketball worldwide. The main aim of this report is to describe the design and evaluation methods used for the XXI Century Academy as a long-term intervention program in the elite Spanish Basketball Academy, aiming to prepare basketball players to compete at the elite level. The monitoring time lasted from 1996 to 2001. A total of 55 players were assigned to the intervention groups based on age, position, maturation level, and country of origin. During this process, participants competed in up to two categories in addition to playing competitive official matches worldwide in international tournaments in their categories and with the national team in the European and World Championships (u-14 - u-18). Participants included 1 NBA player, 3 national A Team players, 10 ACB (First Spanish League) players, 5 LEB (second League) players and 39 LEB-2 EBA (third League) players. Assessments took place in a High-Performance Sports Center (CPT FADURA-GETXO- Basque Government, Getxo, Vizcaya, Spain) and consisted of health questionnaires, anthropometric measures, blood parameters, maturation level, birth age, fitness tests, training volume and intensity, physical activity, technical and tactical training, dietary intake, supplementation and injuries. Each player was assessed 4 times per year (September, December, April, June) for 4 years (16 data points). This is a purely methodological paper describing the design and evaluation methods used in the XXI Century Project, which will be used as a basis for future reporting of results. Therefore, the

    Although both gender- and sports-specific injuries exist among athletes, gender differences in the types of injuries caused by sports activities, except for anterior cruciate ligament (ACL) injury and anterior knee pain, are not well established. An observational study with a retrospective case-series design was conducted to investigate gender-specific differences in the types of injuries sustained while engaging in sports activities common to both males and females. We analyzed injuries sustained during sports activities including basketball, volleyball, tennis, skiing, track and field, and swimming, using data on age, sex, sports activities, activity levels, and sports injuries that had been computerized at our sports medicine (orthopedics) clinic. Inclusion criteria were sports activities that had a record of >100 injuries in total and athletes aged sports activity. We determined the absolute number of patients in each category and their percentage (proportion) of our cohort. The proportions of common injuries caused by sports activities were investigated, and gender-specific differences in the types of common injuries caused by sports activities were clarified. The Fisher exact test was used to determine the significance (P gender-specific differences in the types of sports injuries. According to our database, during the 14-year period between October 1992 and December 2006, a total of 2,989 athletes (1,624 males and 1,365 females) aged sports activities described consulted our sports medicine clinic. The most common sports injuries were ACL injury (14.3%) and knee pain (13.7%), followed by ankle sprain (9.4%), lumbar disc disease (7.0%), meniscus injury (5.1%), stress fracture (2.9%), low back pain (2.5%), patellar tendinitis (2.1%), injury of the medial collateral ligament of the knee (2.0%), lumbar spondylolysis (1.7%), and muscle strain (1.5%). Among these 11 types of sports injuries, a significantly higher proportion of females who engaged in basketball

    Wheelchair sports are an important tool in the rehabilitation of people with severe chronic disabilities and have been a driving force for innovation in technology and practice. In this paper, we will present an overview of the adaptive technology used in Paralympic sports with a special focus on wheeled technology and the impact of design on performance (defined as achieving the greatest level of athletic ability and minimizing the risk of injury). Many advances in manual wheelchairs trace their origins to wheelchair sports. Features of wheelchairs that were used for racing and basketball 25 or more years ago have become integral to the manual wheelchairs that people now use every day; moreover, the current components used on ultralight wheelchairs also have benefitted from technological advances developed for sports wheelchairs. For example, the wheels now used on chairs for daily mobility incorporate many of the components first developed for sports chairs. Also, advances in manufacturing and the availability of aerospace materials have driven current wheelchair design and manufacture. Basic principles of sports wheelchair design are universal across sports and include fit; minimizing weight while maintaining high stiffness; minimizing rolling resistance; and optimizing the sports-specific design of the chair. However, a well-designed and fitted wheelchair is not sufficient for optimal sports performance: the athlete must be well trained, skilled, and use effective biomechanics because wheelchair athletes face some unique biomechanical challenges.

    Full Text Available The submitted article deals with the evaluation of the somatotype of persons and determination of a suitable somatotype for selected sports. In the introduction the method for determining and evaluating a somatotype according to Carter and Heath is characterised. The processes used for calculating the individual components - endomorphy, mesomorphy, ectomorphy - are presented as well as a description of these elements. The calculated components are subsequently put into a somatograph. The evaluation of a somatotype is of great benefit and offers a guideline with the selection of sporting activities; it subsequently helps assign athletes into a suitable position where they will be able to best develop their talents in view of their bodily construction. In this work two types of sports are evaluated - basketball and bodybuilding. With each sport the measurements which give the prerequisites for the given sport are presented. The selection of the presented sports was made with regard to the different requirements and demands in the scope of bodily constitution. The aim of the presented paper is to assess physical parameters of subjects groups in relation to selected sports (basketball and bodybuilding. Based on the body constitution to determine the conditions for developing the physical condition and success in the appointed sports. Another objective is to compare the rating form and equation methods for somatotype determination. The sample consist 32 subjects with age between 22-28 years of both sexes, who are dedicated to basketball, or bodybuilding at amateur level.

    In the field of sports research, there is a growing need for the rigorous collection of data that provide empirical evidence about the complex reality they refer to. Although sports psychology research has advanced considerably in recent years, in both extent and quality, one area of research that remains relatively unexplored is the dynamics of the sports group and the influence of the group on its members (George & Feltz, 1995; Widmeyer, Brawley, & Carron, 1992). Key aspects in this regard include the presence of regularities that are not detectable through visual inference or traditional methods of data analysis, the lack of standard observation instruments, and, assuming priority, the need to develop powerful, computerized coding systems, all of which must form part of an approach that is suitable for natural and habitual contexts. The present study is part of a broader research project concerning ACB teams (first Spanish basketball division) and considers the interaction context before teams try to score (where this is understood as how teams create scoring opportunities) as the core aspect that links team play. This investigation proposes a new model of analysis for studying the effectiveness and construction of offensive basketball plays in order to identify their outcomes, thus providing coaches with an important device for improving or consolidating them.

    The rivalry between the men's basketball teams of Duke University and the University of North Carolina-Chapel Hill (UNC) is one of the most storied traditions in college sports. A subculture of students at each university form social bonds with fellow fans, develop expertise in college basketball rules, team statistics, and individual players, and self-identify as a member of a fan group. The present study capitalized on the high personal investment of these fans and the strong affective tenor of a Duke-UNC basketball game to examine the neural correlates of emotional memory retrieval for a complex sporting event. Male fans watched a competitive, archived game in a social setting. During a subsequent functional magnetic resonance imaging session, participants viewed video clips depicting individual plays of the game that ended with the ball being released toward the basket. For each play, participants recalled whether or not the shot went into the basket. Hemodynamic signal changes time locked to correct memory decisions were analyzed as a function of emotional intensity and valence, according to the fan's perspective. Results showed intensity-modulated retrieval activity in midline cortical structures, sensorimotor cortex, the striatum, and the medial temporal lobe, including the amygdala. Positively valent memories specifically recruited processing in dorsal frontoparietal regions, and additional activity in the insula and medial temporal lobe for positively valent shots recalled with high confidence. This novel paradigm reveals how brain regions implicated in emotion, memory retrieval, visuomotor imagery, and social cognition contribute to the recollection of specific plays in the mind of a sports fan.

    The main goal of the present study was to identify basketball game performance indicators which best determine sports level in the National Basketball Association (NBA) league. The research material consisted of all NBA game statistics at the turn of eight seasons (2003-11) and included 52 performance variables. Through detailed analysis the variables with high influence on game effectiveness were selected for final procedures. It has been proven that a limited number of factors, mostly offensive, determines sports performance in the NBA. The most critical indicators are: Win%, Offensive EFF, 3rd Quarter PPG, Win% CG, Avg Fauls and Avg Steals. In practical applications these results connected with top teams and elite players may help coaches to design better training programs.

    Current recommendations for nutritional interventions in basketball are largely extrapolated from laboratory-based studies that are not sport-specific. We therefore adapted and validated a basketball simulation test relative to competitive basketball games using well-trained basketball players (n = 10), then employed this test to evaluate the effects of two common preexercise nutritional interventions on basketball-specific physical and skilled performance. Specifically, in a randomized and counterbalanced order, participants ingested solutions providing either 75 g carbohydrate (sucrose) 45 min before exercise (Study A; n = 10) or 2 × 0.2 g · kg(-1) sodium bicarbonate (NaHCO3) 90 and 20 min before exercise (Study B; n = 7), each relative to appropriate placebos (H2O and 2 × 0.14 g · kg(-1) NaCl, respectively). Heart rate, sweat rate, pedometer count, and perceived exertion did not systematically differ between the 60-min basketball simulation test and competitive basketball, with a strong positive correlation in heart rate response (r = .9, p basketball simulation test provides a valid reflection of physiological demands in competitive basketball and is sufficiently sensitive to detect meaningful changes in physical and skilled performance. While there are benefits of preexercise carbohydrate or sodium bicarbonate ingestion, these should be balanced against potential negative side effects.

    Full Text Available Purpose: With respect to the fact that every sport field has its own special nature, the aim of present study was to compare competitive state anxiety among team sport and individual sport athletes in Iran. Material: The statistic sample included 120 male athletes, 60 athletes in individual sports (wrestling, taekwondo and karate and 60 athletes in team sports (futsal, volleyball and basketball. The research instrument employed was the Persian version of the Competitive State Anxiety Inventory-2. This inventory was distributed among the subjects about 30 minutes before the first competition. Finally by one-way ANOVA data was analyzed. Results: The results indicated that the mean score of somatic anxiety and cognitive anxiety among individual sport athletes was significantly higher than that of team sport athletes (p0.05. Conclusion: It seems the being part of a team alleviates some of the pressure experienced by those who compete alone. It seems the individual sport athletes may be more exposed to evaluation and more engaged in their own skills and abilities than team sport athletes given that responsibility for performance is not distributed across several performers.

    Surgical treatment for chondral defects of the knee in competitive running and jumping athletes remains controversial. This study evaluated the performance outcomes of professional basketball players in the National Basketball Association (NBA) who underwent microfracture. Data from 24 professional basketball players from 1997 to 2006 was obtained and analyzed. NBA player efficiency ratings (PER) were calculated for two seasons before and after injury. A control group of 24 players was used for comparison. Study group and control group demographics including age, NBA experience, and minutes per game demonstrated no statistical difference. Mean time to return to an NBA game was 30.0 weeks from the time of surgery. The first season after returning to competition PER and minutes per game decreased by 3.5 (P 0.05) and 3.0 min (P NBA game. On return to competition player performance and minutes per game are diminished.

    Context: Lower extremity injuries are common in basketball, yet it is unclear how prophylactic interventions affect lower extremity injury incidence rates. Objective: To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. Data Sources: PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Study Selection: Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 2. Data Extraction: Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Results: Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P basketball athletes. Conclusion: In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. PMID:26502412

    While it is known that long-term intensive athletic training is associated with cardiac structural changes that can be reflected on surface electrocardiograms (ECGs), there is a paucity of sport-specific ECG data. This study seeks to clarify the applicability of existing athlete ECG interpretation criteria to elite basketball players, an athlete group shown to develop significant athletic cardiac remodeling. To generate normative ECG data for National Basketball Association (NBA) athletes and to assess the accuracy of athlete ECG interpretation criteria in this population. The NBA has partnered with Columbia University Medical Center to annually perform a review of policy-mandated annual preseason ECGs and stress echocardiograms for all players and predraft participants. This observational study includes the preseason ECG examinations of NBA athletes who participated in the 2013-2014 and 2014-2015 seasons, plus all participants in the 2014 and 2015 NBA predraft combines. Examinations were performed from July 2013 to May 2015. Data analysis was performed between December 2015 and March 2017.

    Background The onset of jumper's knee is generally associated with sports and sporting activities. Employees in certain professions might be at risk as well for developing jumper's knee. Therefore, it is of interest to identify risk factors in sport and/or occupation. Findings A systematic search of the international scientific literature was performed until November 2008 in the scientific databases (a) Medline, (b) Embase, and (c) SportDiscus. All types of studies were included. The search strategy retrieved ten articles about risk factors in sport that met the inclusion criteria. Risk factors that could be identified are; playing volleyball (4 studies), playing basketball (3 studies), training and playing volleyball/basketball more than 12 hours per week (2 studies), in combination with weight-bearing activities of at least 5 hours per week (1 study) and playing or training on a hard surface (1 study). No studies were found regarding occupation that fulfilled the inclusion criteria. Conclusion Playing volleyball and basketball has a positive association with the onset or worsening of jumper's knee. Other risk factors are training and playing hours of at least 12 hours per week and/or in combination with weight training of at least 5 hours per week, and/or with playing or training on a hard surface. We did not find a specific occupational risk factor. PMID:19586529

    Full Text Available The purpose of this study was to determine how basketball affects the uneven use of the limbs in relation to non-basketball population. Participants were compared by multiple motoric and situational tests, and for each participant tested the relationship between all limbs, both upper and lower. Before the motoric and situational tests participants completed a questionnaire on preference in limb use in everyday life and during sports activities. Participants belong to two groups, one group of young players with the rank of at least four years experience in basketball training, while the second group consists of members of the healthy school population, but with no experience in the continuous training of basketball. The study tested the explosive power of the lower and upper limbs, and the reaction time and agility in the lower limbs. Statistical analysis of results showed significant differences in certain tests between groups and within groups, both among the upper and lower extremities. It can be concluded that basketball as a specific sporting activity has positive influence on the development of the tested variables, while the level of asymmetry at basketball player is less than in the non-basketball population.

    Study Design Prospective diagnostic accuracy validation study. Background Engaging clinicians for diagnosis of patellar tendinopathy in large surveillance studies is often impracticable. A self-report measure, the Oslo Sports Research Trauma Centre patellar tendinopathy (OSTRC-P) Questionnaire, an adaptation of the OSTRC Questionnaire may provide a viable alternative. Objectives To evaluate the diagnostic accuracy of the OSTRC-P Questionnaire in detecting patellar tendinopathy in youth basketball players when compared to clinical evaluation. Methods Following the Standards for Reporting of Diagnostic Accuracy Studies guidelines, 208 youth basketball players (aged 13-18 years) were recruited. Participants completed the OSTRC-P Questionnaire (index test) prior to a clinical evaluation (reference standard) by a physiotherapist blinded to OSTRC-P Questionnaire results. Sensitivity, specificity, predictive values (PVs), likelihood ratios (LRs) and posttest probabilities were calculated. Linear regression was used to examine the association between OSTRC-P Questionnaire severity score and patellar tendinopathy severity rating during single leg decline squat (SLDS). Results The final analysis included 169 players. The OSTRC-P Questionnaire had a sensitivity of 79% (95%CI: 65%, 90%), specificity of 98% (95%CI: 94%, 100%), positive PV of 95%, negative PV of 92%, positive LR of 48 and negative LR of 0.21. The posttest probabilities were 95% and 8% given positive and negative results, respectively. A positive association was found between OSTRC-P Questionnaire and SLDS rating [(β = .08 (95%CI: .03, .12) (p = .001)]. Conclusions The OSTRC-P Questionnaire is an acceptable alternative to clinical evaluation for self-reporting patellar tendinopathy and grading its severity in settings involving youth basketball players.

    To determine if sport specialization increases the risk of anterior knee pain in adolescent female athletes. Retrospective cohort epidemiology study. Female basketball, soccer, and volleyball players (N = 546) were recruited from a single county public school district in Kentucky consisting of 5 middle schools and 4 high schools. A total of 357 multisport and 189 single-sport (66 basketball, 57 soccer, and 66 volleyball) athlete subjects were included due to their diagnosis of patellofemoral pain (PFP) on physical exam. Testing consisted of a standardized history and physician-administered physical examination to determine the presence of PFP. This study compared self-reported multisport athletes with sport-specialized athletes participating in only 1 sport. The sports-participation data were normalized by sport season, with each sport accounting for 1 season of exposure. Incidence rate ratios and 95% confidence intervals (CI) were calculated and used to determine significant differences between athletes who specialized in sport in early youth and multisport athletes. Specialization in a single sport increased the relative risk of PFP incidence 1.5-fold (95% CI 1.0-2.2, P = .038) for cumulative PFP diagnoses. Specific diagnoses such as Sinding Larsen Johansson/ patellar tendinopathy (95% CI 1.5-10.1, P = .005) and Osgood Schlatter disease (95% CI 1.5-10.1, P = .005) demonstrated a 4-fold greater relative risk in single-sport compared with multisport athletes. Incidence of other specific PFP diagnoses such as fat pad, plica, trauma, pes anserine bursitis, and iliotibial-band tendonitis was not different between single-sport and multisport participants (P > .05). Early sport specialization in female adolescents is associated with increased risk of anterior knee-pain disorders including PFP, Osgood Schlatter, Sinding Larsen-Johansson compared with multisport athletes.

  9. TAU INFLUENCE ON DECISION MAKING IN BASKETBALL

    Full Text Available Decision making in sport emerges from the players' interaction with the game context (Araújo, Davids, & Hristovski, 2006. Results from studies on the one-on-one in basketball identified interpersonal distance and relative velocity as relevant variables (i.e., control parameters. These results are reinterpreted in the perspective of the General Tau Theory (Lee, 1998, in which movement is regarded as guided by controlling tau motion-gaps (time to fulfil a gap and taucouplings. Further empirical evidence for this argument, came from a recent study in a team ball sport, where the tau variable was considered and verified as significantly related to decisional behaviour. Following this, it is assumed that the focus in candidate control parameters that detach the spatial component from the temporal one, presented in previous studies, may not be sufficient to explain the decisional behaviour in basketball. In this way, the variable tau is proposed as more informative given that enfolds inextricably spatial-temporal information.

According to our database, during the 20-year period between October 1991 and June 2011, 1,219 basketball players (640 males and 579 females consulted our sports medicine clinic; in total, 1,414 injuries in basketball players (729 injuries in males and 685 injuries in females were recorded. The mean age of patients was 19.6 years. The most common injury site was the knee, followed by the foot and ankle, lower back, and upper extremities. There was a higher proportion of female players presenting with a knee injury, compared with male players (50.4% vs 41.7%, and a lower proportion of female players presenting with an upper extremity injury (5.1% vs 9.7%. The proportion of anterior cruciate ligament injury in the 10–19-year-old age group was higher among female players than among male players (45.9% vs 22.1%, while the proportions of Osgood–Schlatter disease in the 10–19-year-old age group and jumper's knee (patellar and femoral tendinopathy in the 20–29-year-old age group were higher among male players than among female players (12.5% vs 1.8% and 14.6% vs 3.7%, respectively. However, the proportions of other injuries did not differ significantly between male and female players. The present observational study, which was performed using a retrospective case-series design, showed the existence of sex-specific differences in knee injuries sustained while participating in basketball.Keywords: sports injury, sex, anterior cruciate ligament injury, Osgood–Schlatter disease, basketball

    Late-stage rehabilitation programs often incorporate 'sport-specific' demands, but may not optimally simulate the in-game volume or intensity of such activities as sprinting, cutting, jumping, and lateral movement. The aim of this review was to characterize, quantify, and compare straight-line running and multi-directional demands during sport competition. A systematic review of PubMed, CINAHL, SPORTDiscus, and Cochrane Central Register of Controlled Trials databases was conducted. Studies that reported time-motion analysis data on straight-line running, accelerations/decelerations, activity changes, jumping, cutting, or lateral movement over the course of an entire competition in a multi-directional sport (soccer, basketball, lacrosse, handball, field hockey, futsal, volleyball) were included. Data was organized based on sport, age level, and sex and descriptive statistics of the frequency, intensity, time, and volume of the characteristics of running and multi-directional demands were extracted from each study. Eighty-one studies were included in the review (n = 47 soccer, n = 11 basketball, n = 9 handball, n = 7 field hockey, n = 3 futsal, n = 4 volleyball). Variability of sport demand data was found across sports, sexes, and age levels. Specifically, soccer and field hockey demanded the most volume of running, while basketball required the highest ratio of high-intensity running to sprinting. Athletes change activity between 500 and 3000 times over the course of a competition, or once every 2-4 s. Studies of soccer reported the most frequent cutting (up to 800 per game), while studies of basketball reported the highest frequency of lateral movement (up to 450 per game). Basketball (42-56 per game), handball (up to 90 per game), and volleyball (up to 35 per game) were found to require the most jumping. These data may provide an incomplete view of an athlete's straight-line running load, considering that only competition and not practice data was

    Professional basketball players are at risk for lumbar disc herniation (LDH), yet the evidence guiding treatment after operative or nonoperative management of this condition in the National Basketball Association (NBA) is limited. NBA players with LDH will have different performance outcomes based on treatment type. Case-control study. Level 4. Athletes in the NBA with an LDH were identified through team injury reports, transaction records, and public sports archives. A 1:2 case-control study was performed in which LDH players and players without LDH were matched for player variables. Statistical analysis was employed to compare pre- and postindex season performance (games played and player efficiency rating [PER]) and career longevity between test subjects and controls in the operatively treated (OT) and nonoperatively treated (NOT) cohorts. A total of 61 NBA players with LDH were included, of whom 34 underwent discectomy and 27 were managed nonoperatively. Return-to-play (RTP) rates did not differ between NOT and OT players (77.8% vs. 79.4%). When compared with controls, OT players played significantly fewer games and had a lower PER than controls during the first postoperative season, but no difference was seen 2 and 3 years after surgery, with no difference in postoperative career length. In contrast, no difference in games played or PER was seen between NOT players and controls, although NOT players played significantly fewer postindex seasons. NBA players have a high RTP rate regardless of type of treatment for LDH; however, postindex performance differs between surgically and nonoperatively managed patients when compared with players without an LDH. However, further studies with a larger sample size are required for more definitive recommendations. There is a high RTP rate after LDH in the NBA, although postindex performance may differ based on operative versus nonoperative treatment. © 2015 The Author(s).

    Exercise training may increase production of free radicals and reactive oxygen species in different ways. The training type and intensity may influence free radicals production, which leads to differences in oxidative stress status between athletes, but the results of the previous studies are incosistent. The aim of our study was to estimate oxidative stress status in elite athletes engaged in different sport disciplines. The study included 39 male highly skilled professional competitors with international experience (2 Olympic players): 12 wrestlers, 14 soccer players and 13 basketball players in whom we determined the levels of advanced oxidation protein products (AOPP) and malondialdehyde (MDA), as markers of oxidative stress and the total antioxidative capacity (ImAnOX) using commercially available assay kits. The mean AOPP concentration was not significantly different between soccer players, wrestler and basketball players (60.0 ± 23.0 vs. 68.5 ± 30.8 and 80.72 ± 29.1 μmol/L respectively). Mean ImAnOX concentration was not different between soccer players (344.8 ± 35.6 μmol/L), wrestlers (342.5 ± 36.2 μmol/L) and basketball players (347.95 ± 31.3 μmol/L). Mean MDA concentration was significantly higher in basketball players (1912.1 ± 667.7 ng/mL) compared to soccer players (1060.1 ± 391.0 ng/mL, p=0.003). In spite of this fact, oxidative stress markers levels were increased compared to referral values provided by the manufacturer. Type of sports (soccer, wrestler or basketball) have no impact on the levels of oxidative stress markers. Elite sports engagement is a potent stimulus of oxidative stress that leads to the large recruitment of antioxidative defense. Oxidative stress status monitoring followed by appropriate use of antioxidants is recommended as a part of training regime.

    High school female athletes are most likely to sustain a serious knee injury during soccer or basketball, 2 sports that often involve a rapid deceleration before a change of direction or while landing from a jump. To determine if female high school basketball and soccer players show neuromuscular differences during landing and cutting tasks and to examine neuromuscular differences between tasks and between dominant and nondominant sides. A 3-way mixed factorial design investigating the effects of sport (basketball, soccer), task (jumping, cutting), and side (dominant, nondominant). Laboratory. Thirty high school female athletes who listed either basketball or soccer as their only sport of participation (basketball: n = 15, age = 15.1 +/- 1.7 years, experience = 6.9 +/- 2.2 years, height = 165.3 +/- 7.9 cm, mass = 61.8 +/- 9.3 kg; soccer: n = 15, age = 14.8 +/- 0.8 years, experience = 8.8 +/- 2.5 years, height = 161.8 +/- 4.1 cm, mass = 54.6 +/- 7.6 kg). Ground reaction forces, stance time, valgus angles, and valgus moments were assessed during (1) a drop vertical jump with an immediate maximal vertical jump and (2) an immediate side-step cut at a 45 degrees angle. Basketball athletes had greater ground reaction forces (P vertical jump, whereas soccer players had greater ground reaction forces (P vertical jump. Greater valgus moments (P = .006) were noted on the dominant side during cutting. Our subjects demonstrated differences in ground reaction forces and stance times during 2 movements associated with noncontact anterior cruciate ligament injuries. Knee valgus moment and angle were significantly influenced by the type of movement performed. Sport-specific neuromuscular training may be warranted, with basketball players focusing on jumping and landing and soccer players focusing on unanticipated cutting maneuvers.

    To evaluate the prevalence of urinary stress incontinence (USI) in menstruating women practising recreational sports activity, to detect specific sports with a stronger association with urinary incontinence (UI) and to evaluate risk factors possibly related to this condition. Epidemiological study. Non-competitive sports organisations in the province of Varese, Italy. 679 women of fertile age, practising recreational sports activity. Anonymous questionnaire on UI. The questionnaire included questions about patients' general characteristics, occurrence of UI in relation to sport or daily general activities, time of onset of this condition, frequency of leakage episodes, correlation of incontinence with types of movements or sports, subjective impression of being limited on such occasions and/or necessity to modify the type of sport. UI was reported by 101 women (14.9%). Of these, 32 (31.7%) complained of UI only during sports activity, 48 (47.5%) only during daily life and 21 (20.8%) in both circumstances. Body mass index and parity were significantly associated with the risk of UI. Looking at the different sports activities, a higher rate of incontinence was found in women participating in basketball (16.6%), athletics (15%), and tennis or squash (11%). 10.4% of women abandoned their favourite sport, because of USI, and a further 20% limited the way they practised their favourite sport to reduce leakage episodes. Female UI affects a significant proportion of young women practising non-competitive sports activity; it can cause abandonment of the sport or limitation of its practice.

    Full Text Available Aim of the present research was the determination of the attitudes of Greek Basketball coaches towards their distance learning with the use of ICT in comparison with the classical learning and the examination of the perspective of their distance learning with the use of ICT. Therefore a closed questionnaire was used which included 3 different parts. 60 basketball coaches from Northern Greece comprised the sample (N=60. An interactive software was created which included the teaching of an offensive basketball system. The methodology of distance learning was used for the creation of the offensive system. The software was copied to a CD-Rom and accompanied with the questionnaires it was given to 20 Basketball coaches of Northern Greece as a pilot program. After the corrections of the primary questionnaires, the distribution of the final questionnaire accompanied with the CD-Rom followed. Multiple reciprocations were used for the data analysis. According to the results the more relaxing, easier and faster distance learning was considered in relation to the conventional one, a the fewer difficulties would the Basketball coaches face by using the distance learning method and b the friendlier and more relaxing would the distance learning method be. Also according to data research: a the more attractive the reading of software was, b the fewer the difficulties during the reading of software and c the more relaxing, easier and faster distance learning was considered in relation to the conventional one, the stronger was the perspective of Basketball coaches to believe in distance learning. In conclusion the more relaxing, easier and faster distance learning was considered in relation to the conventional one, the more positive were the attitudes of Basketball coaches towards their distance learning, while a positive perspective of Basketball coaches towards their distance learning is being formed.

    The striatum is associated with the learning and retention of motor skills. Several studies have shown that motor learning induces neuronal changes in the striatum. We investigated whether macroscopic change in striatum volume occurs in a segment of the human population who learned basketball-related motor skills and practiced them throughout their entire athletic life. Three-dimensional magnetic resonance imaging volumetry was performed in basketball players and healthy controls, and striatum volumes were compared based on basketball proficiency, region and side. We identified morphological enlargement in the striatum of basketball players in comparison with controls. Our results suggest that continued practice and repetitive performance of basketball-related motor skills may induce plastic structural changes in the human striatum. Copyright © 2010 Elsevier B.V.

    Intermittent sports (e.g., team sports) are diverse in their rules and regulations but similar in the pattern of play; that is, intermittent high-intensity movements and the execution of sport-specific skills over a prolonged period of time (~1-2 h). Performance during intermittent sports is dependent upon a combination of anaerobic and aerobic energy systems, both of which rely on muscle glycogen and/or blood glucose as an important substrate for energy production. The aims of this paper are to review: (1) potential biological mechanisms by which carbohydrate may impact intermittent sport performance; (2) the acute effects of carbohydrate ingestion on intermittent sport performance, including intermittent high-intensity exercise capacity, sprinting, jumping, skill, change of direction speed, and cognition; and (3) what recommendations can be derived for carbohydrate intake before/during exercise in intermittent sports based on the available evidence. The most researched intermittent sport is soccer but some sport-specific studies have also been conducted in other sports (e.g., rugby, field hockey, basketball, American football, and racquet sports). Carbohydrate ingestion before/during exercise has been shown in most studies to enhance intermittent high-intensity exercise capacity. However, studies have shown mixed results with regards to the acute effects of carbohydrate intake on sprinting, jumping, skill, change of direction speed, and cognition. In most of these studies the amount of carbohydrate consumed was ~30-60 g/h in the form of a 6%-7% carbohydrate solution comprised of sucrose, glucose, and/or maltodextrin. The magnitude of the impact that carbohydrate ingestion has on intermittent sport performance is likely dependent on the carbohydrate status of the individual; that is, carbohydrate ingestion has the greatest impact on performance under circumstances eliciting fatigue and/or hypoglycemia. Accordingly, carbohydrate ingestion before and during a game

    Vertical jump performance is one of the key factors in basketball. In order to determine the effectiveness of previously published interventions and their influencing factors we performed a meta-analysis. A computerized search was conducted using the databases PubMed (1966), Web of Science (1900), SPORTDiscus™ (1975),Medline (1966) and SportPilot (2008). Studies involving healthy male or female basketball players at any age and performance level were included. All trials had to investigate the benefits of resistance training programs on jumping performance in basketball players and provide a control group. The effect size (ES) was computed and the relationship between ESs and continuous variables was examined by meta-regressions, whereas subgroup meta-analyses and z-tests were used to assess the impact of categorical moderator variables. The meta-analysis included 14 studies with 20 subgroups and a total of 37 outcomes. A total of 399 participants were examined, N.=157 served as control and N.=242 took part in particular training interventions. The overall weighted ES of 0.78 (95% CI 0.41, 1.15) was significantly greater than zero (Ptraining effect. However, positive correlations were found for training duration (r=0.68; P=0.02). The present meta-analysis demonstrates that resistance training throughout the year, using bodyweight or external weight, significantly improves vertical jump performance in healthy basketball players. Since vertical jump improvements were independent of intervention period but dependent on the duration of each individual training session the total training amount should be based on longer training sessions.

The purpose of this investigation was to examine the structure of coordination motor abilities (CMA in male basketball players at different levels of competition. Material and methods. The study included 183 male basketball players from 10 Polish sports clubs. The examined groups consisted of seniors (n=42 aged 24.5 (± 3.3, juniors (n=37 aged 16.8 (± 0.6, cadets (n=54 aged 14.5 (± 0.1 and children (n=50 aged 13.4 (± 0.2. A battery of motor tests was administered to assess the following CMA: kinesthetic differentiation of movements, spatio-temporal orientation, reaction time, movement coupling, sense of balance, sense of rhythm and adjustment of movements. The structure of CMA under investigation was determined based on the results of Hotelling's principal component analysis in Tucker's modification, completed with Kaiser's Varimax rotation [1, 2]. Results. The CMA structure of basketball players was composed of three or four factors. Most often these included rhythm, movement differentiation, movement coupling and adjustment of movements. Less frequently the structure consisted of spatio-temporal orientation, balance and reaction time. An in-depth analysis of the CMA structure revealed that factors ranged from heterogeneous (children and cadets to homogeneous ones (juniors and seniors. The distribution of identified factors in the common variance was the smallest in children and cadets (58.9% and 62.9%, respectively and the biggest in juniors and seniors (69.3% and 68.48%, respectively.

    Full Text Available Introduction: Basketball is a sport with a high heterogeneity anthropometric as playing position. Point guard is usually the lowest player but also the fastest. Guard is similar to point guard, faster and more agile than the others. Small forward has an intermediate height between the inside and outside players and it combines height with velocity. And center (pivot has a physical role, it has the highest and more muscle mass. The aim of this study is to describe the kinanthropometric profile of male cadet “Valencia Basket Club”. Material and Methods: A total of 20 male cadet basketball players were evaluated (15.35±0.59 years old. An anthropometrist level 1 took anthropometric measures according to the methodology of the International Society for the Advancement of Kinanthropometry (ISAK. Body composition was calculated according to the kinanthropometry consensus of the Kinanthropometry Spanish Group (GREC, somatotype with Heath-Carter’s method and adiposemuscular and cardiovascular risk index. Results: Differences in values of weight, height, skinfold and body composition from variables of sample and position were observed. Lower values were from point guard position and higher values were from center position. An increasing trend of these parameters was established in the following order: point guard, guard, small forward and center. Conclusions: The Valencia Basket Club cadet player overall somatotype is balance ectomorph. To know kinanthropometric profile may be beneficial to develop specific training and nutrition plans as well as to see evolution and characteristics for optimal performance

    The aim of this study was to identify the relative age effect (RAE) in young Polish male (n = 3849) and female (n = 3419) basketball players aged 14 to 22 years competing in the elite games of the Polish Youth Championships. The distribution of birth dates, body height, players' match statistics, and the results of teams participating in championships were identified. The RAE was observed in male and female group, regardless of players age. Nevertheless, the greatest disproportion in the distribution of dates of birth was found in U16 group of boys (V = 0.25, p born in the first half of a calendar year. The research results show the impact of the RAE on the success of youth basketball teams in Poland. The month of birth, body height and sex may determine sporting achievements in youth basketball. Coaches should consider the chronological age and pubertal growth acceleration (APHV-age at peak height velocity) of players to optimize the process of identifying gifted basketball players, especially among boys of 14 years of age.

    Full Text Available Basketball is a sport that has a very long tradition in the territory of ex-Yugoslavia. The breakdown of the country led to a de- crease in quality of basketball in the newly created countries. The unsteadiness of quality of the teams in national leagues resulted in formation of the Regional Adriatic Basketball League (ABA in 2001. The main goal of this research was to measure the competitive balance in ABA, Spanish (ACB and National Basketball Association League (NBA. The competitive balance was calculated by using Ratio of Standard Deviation index (RSD and Herfindahl-Hirschman Index (HHI.The results of RSD showed that the most equable was ABA league, then came ACB league, while the most unequable was NBA league. The calculating of HHI index gave a different result. NBA is the most equable, then comes ABA league, and the last one is ACB league, which is the most unequable according to this parameter. ABA league has less quality than ACB and NBA league, but the results show that it is competitively the most balanced league. According to the RSD rates, NBA league is the most unequable. The main reason for that is a huge number of teams taking part in the league, which causes the unequable distribution of quality players. Ac- cording to HHI, NBA is the most equable. Reason for that are different mechanisms whose goal is to reach and maintain the competitive balance.

    Joint arthroplasty is one of the commonest surgical procedures in orthopedic surgery. In recent years there was an increase in the number of procedures, patient satisfaction and implant survival. Originally, these operations were designed for old patients in order to relieve pain and to enable ambulation. Over the past few years, these operations have become common in younger patients which desire to return to activity, including sports activities. The importance of physical activity is a well known fact. In recent years it became clear that with the proper physical activity the outcomes of the operations are better. There are several types of arthroplasty. Many factors influence the outcome of the operation apart from the post-surgery physical activity. These factors include patient factors, surgical technique and type of arthroplasty. This review summarizes the recommendations for sports activities after hip and knee arthroplasties. These activities are evaluated according to surgeons' recommendations, stress applied on the implant and long term outcomes. The recommended sports activities after joint arthroplasties are walking, swimming and cycling. Soccer, basketball and jogging are not advised. Tennis, downhill skiing and horse riding are recommended with previous experience. There are many more sports activities that patients can participate in, and it is important that the patient discuss the different options prior to the operation. Since these operations are so common, many non-orthopedic physicians encounter these patients in their practice. They should be acquainted with the recommendations for sports activities and encourage them.

    Participation in sports is a popular activity for children across the country. Prevention of sports-related injuries can be improved if details of injuries are documented and studied. A retrospective medical record review of injuries that occurred as a direct result of sports participation (both organized and non-organized play) from November 2006 to November 2007. Because the vast majority of injuries were a result of participation in football or basketball, these injuries were focused upon. The injuries specifically examined were closed head injury (CHI), lacerations and fractures. There were 350 football and 196 basketball injuries (total 546). Comparing injuries between the two groups fractures were found to be more prevalent in football compared to basketball (z = 2.14; p = 0.03; 95%CI (0.01, 0.16)). Lacerations were found to be less prevalent among helmeted patients than those without helmets. (z = 2.39; p = 0.02; 95%CI (-0.17,-0.03)). CHI was more prevalent among organized play compared to non-organized (z = 3.9; pfootball related visits, organized play had a higher prevalence of injury compared to non-organized play (z = 2.87; p = 0.004; 95%CI (0.04.0.21)). No differences in fracture or laceration prevalence were found between organized and non-organized play. Football and basketball related injuries are common complaints in a pediatric Emergency Department. Frequently seen injuries include CHI, fractures and lacerations. In our institution, fractures were more prevalent among football players and CHI was more prevalent among organized sports participants.

    Full Text Available The primary purpose of this study was to identify potential risk factors for sports injuries in professional basketball. An observational retrospective cohort study involving a male professional basketball team, using game tracking data was conducted during three consecutive seasons. Thirty-three professional basketball players took part in this study. A total of 29 time-loss injuries were recorded during regular season games, accounting for 244 total missed games with a mean of 16.26 ± 15.21 per player and season. The tracking data included the following variables: minutes played, physiological load, physiological intensity, mechanical load, mechanical intensity, distance covered, walking maximal speed, maximal speed, sprinting maximal speed, maximal speed, average offensive speed, average defensive speed, level one acceleration, level two acceleration, level three acceleration, level four acceleration, level one deceleration, level two deceleration, level three deceleration, level four deceleration, player efficiency rating and usage percentage. The influence of demographic characteristics, tracking data and performance factors on the risk of injury was investigated using multivariate analysis with their incidence rate ratios (IRRs. Athletes with less or equal than 3 decelerations per game (IRR, 4.36; 95% CI, 1.78-10.6 and those running less or equal than 1.3 miles per game (lower workload (IRR, 6.42 ; 95% CI, 2.52-16.3 had a higher risk of injury during games (p < 0.01 in both cases. Therefore, unloaded players have a higher risk of injury. Adequate management of training loads might be a relevant factor to reduce the likelihood of injury according to individual profiles.

    Guided by Self-Determination Theory (SDT), the present study examined the sport motivation and coping skills of male and female wheelchair basketball players with and without disability (N = 72). In line with SDT, results showed that intrinsic and extrinsic motivation as well as amotivation was found to be present in this sample of wheelchair basketball players. Results also demonstrated that the participants surveyed in the present study scored higher on self-determined types of motivation than non self-determined types of motivation, thus replicating past research with athletes without disability. Furthermore, wheelchair basketball players with and without disability did not differ significantly with respect to sport motivation and coping skills, suggesting that they are more alike than dissimilar. Finally, results revealed that self-determined motivation is associated with enhanced psychological functioning.

    This study aimed to investigate which characteristics of athlete, wheelchair and athlete-wheelchair interface are the best predictors of wheelchair basketball mobility performance. Sixty experienced wheelchair basketball players performed a wheelchair mobility performance test to assess their mobility performance. To determine which variables were the best predictors of mobility performance, forward stepwise linear regression analyses were performed on a set of 33 characteristics, including ten athlete, nineteen wheelchair and four athlete-wheelchair interface characteristics. Eight of the characteristics turned out to be significant predictors of wheelchair basketball mobility performance. Classification, experience, maximal isometric force, wheel axis height and hand rim diameter - which both interchangeable with each other and wheel diameter - camber angle, and the vertical distance between shoulder and rear wheel axis - which was interchangeable with seat height - were positively associated with mobility performance. The vertical distance between the front seat and the footrest was negatively associated with mobility performance. With this insight, coaches and biomechanical specialists are provided with statistical findings to determine which characteristics they could focus on best to improve mobility performance. Six out of eight predictors are modifiable and can be optimized to improve mobility performance. These adjustments could be carried out both in training (maximal isometric force) and in wheelchair configurations (e.g. camber angle).

    Since Hugh Montgomery discovered the first of what are now nearly 200 "fitness genes", together with rapid advances in human gene therapy, there is now a real prospect of the use of genes, genetic elements, and/or cells that have the capacity to enhance athletic performance (to paraphrase the World Anti-Doping Agency's definition of gene doping). This overview covers the main areas of interface between genetics and sport, attempts to provide a context against which gene doping may be viewed, and suggests a futuristic legitimate use of genomic (and possibly epigenetic) information in sport.

    The aim of this study was to examine the effect of volleyball and basketball practice on bone acquisition and to determine which of these 2 high-impact sports is more osteogenic in prepubertal period. We investigated 170 boys (aged 10-12 yr, Tanner stage I): 50 volleyball players (VB), 50 basketball players (BB), and 70 controls. Bone mineral content (BMC, g) and bone area (BA, cm(2)) were measured by dual-energy X-ray absorptiometry at different sites. We found that, both VB and BB have a higher BMC at whole body and most weight-bearing and nonweight-bearing sites than controls, except the BMC in head which was lower in VB and BB than controls. Moreover, only VB exhibited greater BMC in right and left ultra-distal radius than controls. No significant differences were observed between the 3 groups in lumbar spine, femoral neck, and left third D radius BMC. Athletes also exhibited a higher BA in whole body, limbs, lumbar spine, and femoral region than controls. In addition, they have a similar BA in head and left third D radius with controls. The VB exhibited a greater BA in most radius region than controls and a greater femoral neck BA than BB. A significant positive correlation was reported between total lean mass and both BMC and BA in whole body, lumbar spine, total hip, and right whole radius among VB and BB. In summary, we suggest that volleyball and basketball have an osteogenic effect BMC and BA in loaded sites in prepubescent boys. The increased bone mass induced by both volleyball and basketball training in the stressed sites was associated to a decreased skull BMC. Moreover, volleyball practice produces a more sensitive mechanical stress in loaded bones than basketball. This effect seems translated by femoral neck expansion.

    With the advent of the National Collegiate Athletic Association's (NCAA's) mandating the presence and practice of concussion-management plans in collegiate athletic programs, institutions will consider potential approaches for concussion management, including both baseline and normative comparison approaches. To examine sport and team differences in baseline performance on a computer-based neurocognitive measure and 2 standard sideline measures of cognition and balance and to determine the potential effect of premorbid factors sex and height on baseline performance. Cross-sectional study. University laboratory. A total of 437 NCAA Division II student-athletes (males = 273, females = 164; age = 19.61 ± 1.64 years, height = 69.89 ± 4.04 inches [177.52 ± 10.26 cm]) were recruited during mandatory preseason testing conducted in a concussion-management program. The computerized Concussion Resolution Index (CRI), the Standardized Assessment of Concussion (Form A; SAC), and the Balance Error Scoring System (BESS). Players on the men's basketball team tended to perform worse on the baseline measures, whereas soccer players tended to perform better. We found a difference in total BESS scores between these sports (P = .002). We saw a difference between sports on the hard-surface portion of the BESS (F6,347 = 3.33, P = .003, ηp(2) = 0.05). No sport, team, or sex differences were found with SAC scores (P > .05). We noted differences between sports and teams in the CRI indices, with basketball, particularly the men's team, performing worse than soccer (P sport differences, height was a covariate for the team (F1,385 = 5.109, P = .02, ηp(2) = 0.013) and sport (F1,326 = 11.212, P = .001, ηp(2) = 0.033) analyses, but the interaction of sex and sport on CRI indices was not significant in any test (P > .05). Given that differences in neurocognitive functioning and performance among sports and teams exist, the comparison of posttraumatic and baseline assessment may lead to more

    Safety of Sports for ICD Patients. The safety of sports participation for patients with implantable cardioverter defibrillators (ICDs) is unknown, and recommendations among physicians may vary widely. The purposes of this study were to determine current practice among patients with ICDs and their physicians regarding sports participation, and to determine how many physicians have cared for patients who have sustained adverse events during sports participation. A survey was mailed to all 1,687 U.S. physician members of the Heart Rhythm Society. Among 614 respondent physicians, recommendations varied widely. Only 10% recommended avoidance of all sports more vigorous than golf. Seventy-six percent recommended avoidance of contact, and 45% recommend avoidance of competitive sports. Most (71%) based restrictions on patients' underlying heart disease. Regardless of recommendations, most physicians (71%) reported caring for patients who participated in sports, including many citing vigorous, competitive sports, most commonly cited were basketball, running, and skiing. ICD shocks during sports were common, cited by 40% of physicians. However, few adverse consequences were reported. One percent of physicians reported known injury to patient (all but 3 minor); 5%, injury to the ICD system, and weightlifting and golf. Physician recommendations for sports participation for patients with ICDs varies widely. Many patients with ICDs do participate in vigorous and even competitive sports. While shocks were common, significant adverse events were rare.

    Context: Mini-basketball is one of the most popular junior sports in Japan. Mini-basketball–related injuries may increase because of early specialization. However, no reports have been published to date concerning basketball injuries in children younger than 12 years of age. Objective: To prospectively study the incidence, sites, types, and mechanisms of injuries in mini-basketball teams. Design: Descriptive epidemiology study. Setting: Mini-basketball teams in Kobe, Japan. Patients or Other Participants: A total of 95 players in 7 community-based mini-basketball club teams (age range, 9 through 12 years). Main Outcome Measure(s): Data on all practice and game injuries for the 2013–2014 season were collected using an injury report form. Injury rates were calculated according to site, type, and mechanism. Results: The overall injury rate was 3.83 per 1000 athlete-hours (AHs). The game injury rate (12.92/1000 AHs) was higher than the practice injury rate (3.13/1000 AHs; P basketball players. The high practice injury rate in this study may be due to specific factors related to growth, such as individual differences in height, or to skills, such as inexperience in ball handling.

    The aim of this study was to compare the effects of plyometric training versus basketball technique training on improving neuro-muscular performance. Thirty-six (age 14.9±0.9 years, body height 164.0±7.6 cm, body weight 54.0±8.7 kg, BMI 20.1±2.4 kg·m-2) basketball players girls were randomly allocated to 2 groups: Basketball Plyometric Training (BPT, N.=18) and Basketball Technique Training (BTT, N.=18). The players were tested by two specific tests: counter movement jump (CMJ) and squat jump (SJ) before and after 6 training weeks. The jump height, as dependent variable, showed a different trend as an effect of the different training protocols, in contrast with the current knowledge. Manova did not show significant interactions between the two groups for the height of jumps, while significant differences were found for interaction time × training (Ptraining, the BPT group increased significantly CMJ performance by 11.3% (Ptraining protocols proposed in this study improved vertical jump performance. However, a combination of the two protocols, plyometric training and sport-specific-exercises, could be useful to optimize performance by an easy transition from controlled a-specific to sport-specific performance requirements. In conclusion, BPT is a safe and effective method of achieving a favourable neuro-muscular performance than BTT in female basketball players.

    Currently, there is no overview of the incidence and (basketball-specific) risk factors of musculoskeletal injuries among recreational basketball players, nor any insight into the effect of preventive measures on the incidence of basketball injuries. This study aimed to gather systematically the scientific evidence on the incidence, prevalence, aetiology and preventive measures for musculoskeletal injuries among recreational basketball players. Highly sensitive search strategies were built based on three groups of keywords (and related search terms). Two electronic databases were searched, namely Medline (biomedical literature) via Pubmed, and SPORTDiscus (sports and sports medicine literature) via EBSCOhost. The incidence of musculoskeletal injuries among recreational basketball players ranged from 0.0047 injuries per 1,000 athlete-exposures (AE) for dental injuries to 10.1 injuries per 1000 AE for overall injuries during match play. Significant risk factors for injuries were defending, postural sway, high vertical ground reaction force during jumping and weight >75 kg. All prevention studies have shown to have a significant effect on reducing the risk of injury ranging from an odds ratio (95% confidence interval (CI)) of 0.175 (0.049-0.626) for training injuries and a relative risk (95% CI) of 0.83 (0.57-1.19) achieved with FIFA 11+ prevention exercises and sport-specific balance training, relatively. In order to gain insight in the aetiology of basketball-specific injuries and consequently facilitate the development of preventive strategies, more high quality basketball-specific and injury-specific studies among recreational basketball players are needed.

    The purpose of this study is to adapt imported instruments for measuring multidimensional perfectionism in sport situations and perceived group cohesion, in terms of construct validity and reliability, as well as from the aspect of interpretability, addressed on Croatian samples of athletes. Group Environment Questionnaire (GEQ) and Sport Multidimensional Perfectionism Scale (MSSP) are applied. The sample of 223 male Croatian athletes comprises of N1 = 107 top basketball players from nine teams in A-1 Croatian Basketball League and N2 = 116 recreational table tennis players who play in Table Tennis Organization of Clubs and Actives in Zagreb. Principal Components Analyses at both instruments showed two-component structures: combined social-task cohesion and friendship were latent dimensions of perceived group cohesion, while the internalized standards and externalized standards revealed two aspects of multidimensional perfectionism in sport situations. In perceived group cohesion, basketball players achieved higher average results than table tennis players in the friendship, while the table tennis players showed higher combined social and task orientation than basketball players. In multidimensional sport perfectionism, basketball players have higher average result than table tennis players in the dimension of internalized perfectionism, but in externalized perfectionism there is no statistical significant difference. Younger players showed higher average results than older players in the dimension of friendship, while older players showed higher combined social and task orientation than younger players. Younger players have higher average scores in internalized perfectionism. The main importance of the research is adjustment of multidimensional perfectionism in sport situations and perceived group cohesion to Croatian athletes, providing additional possibility of cross-cultural adjustment of both concepts, psychometrically and theoretically.

    In female basketball the assumed components of success include power, agility, and the proficiency at executing movements using each limb. However, the importance of these attributes in discriminating between playing levels in female basketball have yet to be determined. The purpose of this study was to compare lower body power, change of direction (COD) speed, agility, and lower-body sidedness between basketball athletes participating in Division 1 Collegiate basketball (United States), Women's National Basketball League (WNBL) (Australia), and Women's National Basketball Association (WNBA) (United States). Fifteen female athletes from each league (N = 45) completed a double and single leg counter-movement jump, static jump, drop jump, 5-0-5 COD Test, and an offensive and defensive Agility Test. One-way analysis of variance with post-hoc comparisons, were conducted to compare differences in physical characteristics (height, body mass, age) and performance outcomes (jump, COD, agility assessments) between playing levels. Separate dependent t-tests were performed to compare lower body sidedness (left vs. right lower-limbs) during the single-leg CMJ jumps (vertical jump height) and 5-0-5 COD test for each limb within each playing level. WNBA athletes displayed significantly greater lower body power (P = 0.01 - 0.03) compared to WNBL athletes, significantly faster COD speed (P = 0.02 - 0.03), and offensive and defensive agility performance (P = 0.02 - 0.03) compared to WNBL and Collegiate athletes. WNBL athletes also produced faster defensive agility performance compared to Collegiate athletes (P = 0.02). Further, WNBA and WNBL athletes exhibited reduced lower body sidedness compared to Collegiate athletes. These findings indicate the importance of lower body power, agility, and reduced lower body imbalances to execute more proficient on court movements, required to compete at higher playing levels.

    Basketball can be described as a moderate-to-long duration exercise including repeated bouts of high-intensity activity interspersed with periods of low to moderate active recovery or passive rest. A match is characterized by repeated explosive activities, such as sprints, jumps, shuffles and rapid changes in direction. In top-level modern basketball, players are frequently required to play consecutive matches with limited time to recover. To ensure adequate recovery after any basketball activity (i.e., match or training), it is necessary to know the type of fatigue induced and, if possible, its underlying mechanisms. Despite limited scientific evidence to support their effectiveness in facilitating optimal recovery, certain recovery strategies are commonly utilized in basketball. It is particularly important to optimize recovery because players spend a much greater proportion of their time recovering than they do in training. Therefore, the main aim of this report is to facilitate useful information that may lead to practical application, based on the scientific evidence and applied knowledge specifically in basketball.

    The aim of this study was to analyze the psychometric properties of the Portuguese version of the Motivational Climate Sport Youth Scale (MCSYSp) and invariance across gender and different sports (swimming, soccer, handball, basketball, futsal). A total of 4,569 athletes (3,053 males, 1,516 females) from soccer (1,098), swimming (1,049), basketball (1,754), futsal (340), and handball (328) participated in this study, with ages between 10 and 20 years (M = 15.13; SD = 1.95). The results show that the original model (two factors/12 items) did not adjust to the data in a satisfactory way; therefore, it was necessary to change the model by removing four items (two from each factor). Subsequently, the model adjusted to the data in a satisfactory way (χ 2 = 499.84; df = 19; χ 2 /df = 26.30; p sports (soccer, handball, basketball, futsal) (ΔCFK≤.01); however, it was not invariant between swimming and team sports (soccer, handball, basketball, futsal) (ΔCFI ≥ .01). In conclusion, the MCSYSp (two factors/eight items) is a valid and reliable choice that is transversal not only to gender, but also to the different studied team sports to measure the perception of the motivational climate in athletes. Future studies can research more deeply the invariance analysis between individual sports to better understand the invariance of the model between individual and team sports.

    Full Text Available The article presents data on contemporary views of the prevalence, causes, circumstances of sudden cardiac death, and its prevention measures in children and adolescents during sports activity. It notes a difficulty in defining the epidemiology of the above condition because the data are primarily based upon mass media news coverage. The incidence of sudden cardiac death is approximately 1 per 100,000 young athletes; more than 90% boys die. The sports, during which sudden cardiac death often occurs, include (both American and European football, basketball, and hockey. Sudden cardiac death due to cоmmоtio cordis (life-threatening cardiac arrhythmias resulting from a blow with a blunt instrument to the area of the heart during the vulnerable phase of the cardiac cycle is considered separately. Children who die suddenly during sports are frequently detected to have hypertrophic cardiomyopathy or myocarditis; but no changes are found in more than 50% of cases at autopsy, which is suggestive of primary arrhythmogenic death. The basis for prevention is the early detection of diseases that can cause sudden death during sports, regular examination, knowledge of ECG characteristics in athletes, and first aid techniques, including the use of automated external defibrillators.

    Research indicates that planned and reactive agility are different athletic skills. These skills have not been adequately assessed in male basketball players. To define whether 10-m-sprint performance and planned and reactive agility measured by the Y-shaped agility test can discriminate between semiprofessional and amateur basketball players. Ten semiprofessional and 10 amateur basketball players completed 10-m sprints and planned- and reactive-agility tests. The Y-shaped agility test involved subjects sprinting 5 m through a trigger timing gate, followed by a 45° cut and 5-m sprint to the left or right through a target gate. In the planned condition, subjects knew the cut direction. For reactive trials, subjects visually scanned to find the illuminated gate. A 1-way analysis of variance (P basketball players; planned agility did not. To distinguish between male basketball players of different ability levels, agility tests should include a perceptual and decision-making component.

    Full Text Available Maintenance of the sporting activity of elite athletes in adapted sports can be difficult if a secondary disorder, such as a pressure ulcer, occurs. Pressure ulcers result from deep tissue injuries by external pressure. The purpose of this study was to use ultrasonography to investigate deep tissue injuries in male wheelchair basketball players of a Japanese national team, and to determine factors associated with the injuries (e.g., body mass index, class of wheelchair basketball, underlying disease, length of athletic career, and whether use of wheelchair is primarily for playing basketball. Twenty male Japanese wheelchair basketball players on the national team for the 2012 London Paralympic Games (12 representative players and eight candidate representative players participated in this study. The sacral region and bilateral ischial regions in each athlete were examined by ultrasonography to detect low-echoic lesions indicative of deep tissue injuries. Nine (45% players had low-echoic lesions, which were detected in 10 of 60 areas. Eight lesions were detected in the sacral region and two lesions were detected in the ischial region. More players with spinal cord injury had low-echoic lesions [9 (69.2% of 13 players], compared to players with skeletal system disease [0 (0% of 7 players, p = 0.002]. Players who used a wheelchair in daily life were more likely to have low-echoic lesions [8 (66.74% of 12 players], compared to players who primarily used a wheelchair for playing basketball [1 (12.5% of 8 players, p = 0.010]. Deep tissue injuries were detected in 45% of male Japanese wheelchair basketball players on the national team. Players with spinal cord injury and players who used a wheelchair in daily life were more likely to have deep tissue injuries, particularly in the sacral region. The lesions were small, but a periodic medical check should be performed to maintain athletes' sporting life.

    This study aimed to provide a comprehensive strength-based physiological profile of women's NCAA Division I basketball and gymnastic athletes; and to make sport-specific comparisons for various strength characteristics of the knee flexor and extensor muscles. A focus on antagonist muscle balance (hamstrings-to-quadriceps ratios, H:Q) was used to elucidate vulnerabilities in these at-risk female athletes. Fourteen NCAA Division I women's basketball and 13 gymnastics athletes performed strength testing of the knee extensors and flexors. Outcome measures included absolute and relative (body mass normalised) peak torque (PT), rate of torque development at 50, 100, 200 ms (RTD50 etc.) and H:Q ratios of all variables. The basketball athletes had greater absolute strength for all variables except for isokinetic PT at 240°s -1 and isometric RTD50 for the knee extensors. Gymnasts showed ~20% weaker body mass relative concentric PT for the knee flexors at 60 and 120°·s -1 , and decreased conventional H:Q ratios at 60 and 240°·s -1 (~15%). These findings suggest that collegiate level gymnastics athletes may be prone to increased ACL injury risk due to deficient knee flexor strength and H:Q strength imbalance. Coaches may use these findings when implementing injury prevention screening and/or for individualised strength training programming centered around an athletes strength-related deficits.

    Considering the growth in research, examining the development of mainstream sport athletes over the past two decades, studies examining development of athletes with disabilities have been surprisingly limited. While similarities in developmental trajectories between the two cohorts may exist regarding factors such as the value of practice, which tend to be universal regardless of context, disability-related issues (e.g. whether the disability was congenital or acquired) may influence the course of development, affecting variables such as starting age, training and developmental milestones. Fifty-two male and female athletes training with the Wheelchair Basketball Canada National Academy provided detailed training histories. Athletes illustrated similar developmental patterns (e.g. milestones, training adjustments) as they progressed through their sporting career. However, athletes with congenital disabilities started participation in wheelchair basketball and unorganised practice at significantly younger ages (t 49  = -4.35, p training throughout their sporting career. Future work may consider examining developmental trajectories and training histories of athletes in various parasports to extend our understanding of their development and skill acquisition.

    The purpose of this study was two-fold. First, to examine the impact exercise-induced muscle damage (EIMD) on physical fitness qualities following a basketball-specific training session. Secondly, to determine the reproducibility of the sport-specific performance measures in elite female basketball players. Ten elite female basketball players (age 25.6 ± 4.5 years; height 1.8 ± 0.7m; body mass 76.7 ± 8.3kg) undertook a 90-minute training session involving repeated jumping, sprinting and game-simulated training. Indirect muscle damage markers (i.e., countermovement jump [CMJ], delayed-onset of muscle soreness [DOMS] and creatine kinase [CK]) and sport-specific performances (i.e., change of direction [COD] and suicide test [ST]) were measured prior to and 24 hours post training. These measures were also collected one week following training to determine the reproducibility of the basketball-specific performance measures. A significant reduction in lower-body power (-3.5±3.6%; P0.05). The intra-class correlation coefficient and coefficient of variation for the COD and ST were 0.81 and 0.90, respectively, and 1.9% and 1.5%, respectively. In conclusion, appropriate recovery should be considered the day following basketball-specific training sessions in elite basketball players. Furthermore, this study showed the usability of performance measures to detect changes during periods of EIMD, with acceptable reproducibility and minimal measurement error.

  8. Carbohydrate Nutrition and Team Sport Performance.

    Science.gov (United States)

    Williams, Clyde; Rollo, Ian

    2015-11-01

    The common pattern of play in 'team sports' is 'stop and go', i.e. where players perform repeated bouts of brief high-intensity exercise punctuated by lower intensity activity. Sprints are generally 2-4 s long and recovery between sprints is of variable length. Energy production during brief sprints is derived from the degradation of intra-muscular phosphocreatine and glycogen (anaerobic metabolism). Prolonged periods of multiple sprints drain muscle glycogen stores, leading to a decrease in power output and a reduction in general work rate during training and competition. The impact of dietary carbohydrate interventions on team sport performance have been typically assessed using intermittent variable-speed shuttle running over a distance of 20 m. This method has evolved to include specific work to rest ratios and skills specific to team sports such as soccer, rugby and basketball. Increasing liver and muscle carbohydrate stores before sports helps delay the onset of fatigue during prolonged intermittent variable-speed running. Carbohydrate intake during exercise, typically ingested as carbohydrate-electrolyte solutions, is also associated with improved performance. The mechanisms responsible are likely to be the availability of carbohydrate as a substrate for central and peripheral functions. Variable-speed running in hot environments is limited by the degree of hyperthermia before muscle glycogen availability becomes a significant contributor to the onset of fatigue. Finally, ingesting carbohydrate immediately after training and competition will rapidly recover liver and muscle glycogen stores.

    The nutritional practices of athletes are critical to sports performance, since good result is the goal or expectations of all sports stake-holders, coaches, sports administrators/managers and spectators alike, therefore the issue of good nutrition regarding these "human machines" (athletes), calls for serious attention. This research, therefore tried to examine the nutritional practices of some selected Basketball players of Nnamdi Azikiwe University (UNIZIK) Awka, in Anambra State of Nigeria. Some 59 male and female Basketball (B/B) players were purposefully selected to participate in the study. A self developed questionnaire (r = 0.71) was administered on them and Weighted Mean Score (WMS). This was in an attempt to ascertain whether the dietary manipulations as practiced by these athletes immediately before competition, affect their performance, in any way. Findings revealed daily inadequate consumption of required proportion of nutrients and very poor timing of meals by the players.

    The basketball is a complex sport, which these days has become increasingly linked to its’ psychophysical aspects rather than to the technical ones. Therefore, it is important to make a through study of the passing techniques from the point of view of the type of the pass and its’ biomechanics. From the point of view of the type of the used passes, the most used is the two-handed chest pass with a frequency of 39.9%. This is followed, in terms of frequency, by one-handed passes – the baseball...

    The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants performed 10 repetitions of the following sequence: Abalakov jump, Change-of-Direction and Acceleration Test (CODAT) and two free throws. Later, heart rate, body impacts and game statistics were recorded during a 20-min simulated basketball game. In comparison to the placebo, the ingestion of caffeine increased mean jump height (37.3 ± 6.8 vs. 38.2 ± 7.4 cm; p = 0.012), but did not change mean time in the CODAT test or accuracy in free throws. During the simulated game, caffeine increased the number of body impacts (396 ± 43 vs. 410 ± 41 impacts/min; p basketball players. PMID:28925969

    To investigate the epidemiology of eye injuries sustained by professional basketball players in the National Basketball Association (NBA). A prospective study involving all NBA athletes who sustained eye injuries between February 1, 1992, and June 20, 1993, was conducted. Twenty-seven NBA team athletic trainers, physicians, and ophthalmologists were provided data forms to complete for any player examined for an eye injury. Practice and game exposures during the preseason, regular season, playoffs, and championships were included. Of the 1092 injuries sustained by NBA players during the 17-month period, 59 (5.4%) involved the eye and adnexa. Eighteen (30.5%) of the injuries occurred while the player was in the act of rebounding, and 16 (27.1%) while the player was on offense. The most common diagnoses included 30 abrasions or lacerations to the eyelid (50.9%), 17 contusions (edema and/or ecchymosis) to the eyelid or periorbital region (28.8%), and seven corneal abrasions (11.9%). There were three orbital fractures (5.1%). Most injuries were caused by fingers (35.6%) or elbows (28.8%). Nine players (15.3%) missed subsequent games because of their injury. Fifty-seven players (96.6%) were not wearing protective eyewear at the time of injury. The incidence of eye injuries in NBA players during the 17-month period was 1.44 per 1000 game exposures. Frequent physical contact in professional basketball players leaves them at great risk for sustaining eye injuries. To prevent these injuries, protective eyewear is recommended.

    To assess sleep patterns and associations between sleep and match performance in elite Australian female basketball players. Prospective cohort study. Seventeen elite female basketball players were monitored across two consecutive in-season competitions (30 weeks). Total sleep time and sleep efficiency were determined using triaxial accelerometers for Baseline, Pre-match, Match-day and Post-match timings. Match performance was determined using the basketball efficiency statistic (EFF). The effects of match schedule (Regular versus Double-Header; Home versus Away) and sleep on EFF were assessed. The Double-Header condition changed the pattern of sleep when compared with the Regular condition (F (3,48) =3.763, P=0.017), where total sleep time Post-match was 11% less for Double-Header (mean±SD; 7.2±1.4h) compared with Regular (8.0±1.3h; P=0.007). Total sleep time for Double-Header was greater Pre-match (8.2±1.7h) compared with Baseline (7.1±1.6h; P=0.022) and Match-day (7.3±1.5h; P=0.007). Small correlations existed between sleep metrics at Pre-match and EFF for pooled data (r=-0.39 to -0.22; P≥0.238). Relationships between total sleep time and EFF ranged from moderate negative to large positive correlations for individual players (r=-0.37 to 0.62) and reached significance for one player (r=0.60; P=0.025). Match schedule can affect the sleep patterns of elite female basketball players. A large degree of inter-individual variability existed in the relationship between sleep and match performance; nevertheless, sleep monitoring might assist in the optimisation of performance for some athletes.

    2015-01-01

    The purpose of the present study was to investigate sex-specific differences in injury types among basketball players. According to our database, during the 20-year period between October 1991 and June 2011, 1,219 basketball players (640 males and 579 females) consulted our sports medicine clinic; in total, 1,414 injuries in basketball players (729 injuries in males and 685 injuries in females) were recorded. The mean age of patients was 19.6 years. The most common injury site was the knee, followed by the foot and ankle, lower back, and upper extremities. There was a higher proportion of female players presenting with a knee injury, compared with male players (50.4% vs 41.7%), and a lower proportion of female players presenting with an upper extremity injury (5.1% vs 9.7%). The proportion of anterior cruciate ligament injury in the 10-19-year-old age group was higher among female players than among male players (45.9% vs 22.1%), while the proportions of Osgood-Schlatter disease in the 10-19-year-old age group and jumper's knee (patellar and femoral tendinopathy) in the 20-29-year-old age group were higher among male players than among female players (12.5% vs 1.8% and 14.6% vs 3.7%, respectively). However, the proportions of other injuries did not differ significantly between male and female players. The present observational study, which was performed using a retrospective case-series design, showed the existence of sex-specific differences in knee injuries sustained while participating in basketball.

    The aim of this study is to identify the kinetic principal components involved in one-leg running vertical jumps, as well as the potential differences between specialists from different sports. The sample was composed of 25 regional skilled athletes who play different jumping sports (volleyball players, handball players, basketball players, high jumpers and novices), who performed a running one-leg jump. A principal component analysis was performed on the data obtained from the 200 tested jumps in order to identify the principal components summarizing the six variables extracted from the force-time curve. Two principal components including six variables accounted for 78 % of the variance in jump height. Running one-leg vertical jump performance was predicted by a temporal component (that brings together impulse time, eccentric time and vertical displacement of the center of mass) and a force component (who brings together relative peak of force and power, and rate of force development). A comparison made among athletes revealed a temporal-prevailing profile for volleyball players, and a force-dominant profile for Fosbury high jumpers. Novices showed an ineffective utilization of the force component, while handball and basketball players showed heterogeneous and neutral component profiles. Participants will use a jumping strategy in which variables related to either the magnitude or timing of force production will be closely coupled; athletes from different sporting backgrounds will use a jumping strategy that reflects the inherent demands of their chosen sport.

    Full Text Available Goals of this research were to determine the correlations among the dimensions of relevant factors about engagement of women in sports, as well as to determine the differences in the dimensions of relevant factors about engagement of women in sports, according to several independent variables: type of sport, educational level, marital status and place of living. A total of 342 female athletes and other sport practitioners are examined, with the average age of 31.53±13.92 years (M±SD from several Croatian sport federations: judo, badminton, gymnastics, bowling, acrobatic rock’n roll, handball, sport fishing, Association of the deaf athletes, archery, chess and basketball. The results revealed that according to the type of sport, the differences are statistically significant for: negative environment, relaxation/fun and ambition/self-esteem motives; environmental, obligation and financial/traffic/rules barriers; indirect strategies and already present initiatives for including women in sports. According to the education level, the differences are statistically significant for: positive personal, negative environmental motives and ambition/self-esteem motives; obligations as the barriers; organization out-of-sport commitments and specific strategies for media. The differences in the marital status of participants are statistically significant for the variables: positive personal, negative environmental and ambition/self-esteem motives; environmental and obligation barriers; organization of out-of-sport commitments. At last, only two statistically significant differences are found according to the place of living: for indirect strategies for including women in sports and for the programs created only for women. The results provide the platform for developing programs and strategies for retaining and engaging women in particular sports in Croatia.

    Basketball is a popular US high school sport with more than 1 million participants annually. To compare patterns of athletes with basketball-related injuries presenting to US emergency departments from 2005 through 2010 and the high school athletic training setting from the 2005-2011 seasons. Descriptive epidemiology study. Data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission and the High School Reporting Information Online database. Complex sample weights were used to calculate national estimates of basketball-related injuries for comparison. Adolescents from 13 to 19 years of age treated in US emergency departments for basketball-related injuries and athletes from 13 to 19 years of age from schools participating in High School Reporting Information Online who were injured while playing basketball. Nationally, an estimated 1,514,957 (95% confidence interval = 1,337,441, 1,692,474) athletes with basketball-related injuries reported to the emergency department and 1,064,551 (95% confidence interval = 1,055,482, 1,073,620) presented to the athletic training setting. Overall, the most frequent injuries seen in the emergency department were lacerations and fractures (injury proportion ratios [IPRs] = 3.45 and 1.72, respectively), whereas those seen in the athletic training setting were more commonly concussions and strains/sprains (IPRs = 2.23 and 1.19, respectively; all P values training setting (IPR = 1.18; all P values basketball players presenting for treatment in the emergency department and the athletic training setting. Understanding differences specific to clinical settings is crucial to grasping the full epidemiologic and clinical picture of sport-related injuries. Certified athletic trainers play an important role in identifying, assessing, and treating athletes with sport-related injuries who might otherwise present to clinical settings with higher costs, such as the emergency department.

    Injuries are common during sport activities, a part of which is also injuries to the stomatognathic system. According to the data from literature orofacial injuries are frequent, but relatively minor. World Dental Federation has listed basketball as a medium-risk sport in sustaining orofacial injuries. The purpose of this investigation was to determine incidence, type and severity of orofacial injuries during basketball and frequents of mouthguard use. The sample consisted of 195 athletes who actively participate in basketball, 60 amateurs/non-professional and 135 professionals. A total of 2 265 injuries to the stomatognathic system were documented in this research; 200 (8.8%) of those injuries refer to the non-professionals and 2 065 (91.2%) to the professionals. The most common injuries are lacerations and contusions of soft tissue (a total of 2 208 or 97.5%), followed by dental injuries (a total of 57 or 2.5%). Out of all recorded laceration injuries 59.8% lacerations of soft tissue occurred during practice (12.6% amateurs and 87.4% professionals), while 40.2% of them occurred during games (2.5% amateurs and 97.5% professionals). Of a total of 57 dental injuries recorded during an athletes career, in 78.9% it were the professionals who suffered an injury, and in 21.1% of them the amateurs. Out of a total of 195 basketball players only 1% (2 players - one professional and one amateur) frequently used mouthguard during practice and games, while 93.3% of them never tried to wear a mouthguard. Such low percentage of mouthguard use in basketball players reflects poor awareness and education of athletes and coaches, as well as insufficient role of dentists in education. Orofacial injuries during basketball are not severe (80% lacerations), and therefore do not stimulate the use of a protecting devices even their use will totally diminish this type of injuries.

    Full Text Available Aim: The aim of this study is to investigate the relation between the academic success levels of the boys playing basketball and certain variables such as age, basketball playing times, the number of the weekly average trainings and motoric skills. Material and Methods: 93 students participated voluntarily in the study from three different sports clubs. The ages in which the participants started basketball varied between 10 and 13, and their durations of weekly trainings differed from each other. The end-of-the-year academic success average points of the participants were considered in determining the academic success levels; and the International Physical Performance Test Profile (IPPTP (Kamar, 2008 was used in measuring the motoric skills. The issue of whether there was a significant difference between the participants was determined by using the SPSS 21.0 Package Program together with the One-Way ANOVA Test. Results: According to the findings, it was determined that there were no relations between the academic success rates and the basketball playing durations, the number of weekly trainings, and their motoric skills (p>0.05. On the other hand, a statistically significant difference was determined between the age variable and the academic success levels (p<0.05. Conclusions: No significant differences were detected between the motoric skills, number of trainings, starting basketball dates and the academic success levels of the sportsmen who receive basic basketball training (which contribute to the development of motoric skills with different numbers of weekly training and with different basketball starting dates; while a negative significance was detected between the age variable and academic success.

    Although sport for athletes with mental retardation (MR) is achieving an important role, the literature concerning basketball tests and training is still poor. The aims of this study were to verify whether the basketball test battery could be an appropriate modality to classify the players in the Promotion (Pro) category, to assess basketball abilities before (PRE) and after (POST) an 8-month training in players with MR in relation to Competitive (Comp) and Pro categories, to analyze the variation of specific basketball abilities based on subjects' MR diagnosis. Forty-one male basketball players with MR (17 Comp and 24 Pro; age range 18-45 years; MR: 15% mild, 54% moderate, 29% severe, and 2% profound) were assessed PRE and POST training through the basketball test battery, which assessed 4 ability levels of increasing difficulty (from I to IV), each one characterized by the analysis of fundamental areas (ball handling, reception, passing, and shooting). Level I was significantly changed after the intervention period regardless of the Category, whereas shooting was affected by the interaction between Category and Intervention. The results showed significant differences between categories in the scores of individual global, level I, level II, level III, and in all fundamental areas. Individual global score in both categories significantly increased. The players of Comp significantly improved in level III, in ball handling, reception, passing, and shooting scores. The players of Pro improved significantly in level II, in ball handling, reception, and passing scores. Individual global, ability levels I-III, and fundamental area scores were negatively correlated to the MR level indicating that the players with a lower MR obtained higher ability scores. In conclusion, it was found that the basketball test battery could be useful for improving and monitoring training in both Comp and Pro players.

Material & Methods: the analysis of scientific-methodical literature, educational testing, pedagogical experiment, methods of mathematical statistics. For determination and assessment physical efficiency of students – basketball players used the Harvard step test. In pedagogical testing for assessing special performance was attended by 14 students – basketball players (n=14 men's teams of the Medical Institute of Sumy State University. Results: the analysis of scientific and technical literature showed gaps in training basketball players, namely, to improve the physical performance. Especially these problems are when basketball training sessions combine with study in higher educational institutions. The load that caused a combination of mental and physical labor is enough to affect on the performance, develop resistance to fatigue. Still need to look for approaches that can help in conditions of single 3-4 workouts per week to maintain a high level of physical capacity of basketball players. Conclusions: analyzing the test results of basketball team players at Medical Institute of Sumy State University, we can say that the level of physical performance is satisfactory and functional status is mediocre. Players need more regular training which includes special exercises with high intensity close to competitive conditions

    The effect of intensive long-term physical activity on phospholipid fatty acid (FA) composition has not been studied thoroughly. We determined plasma and erythrocyte phospholipid FA status of professional basketball and football players. Our results showed differences in plasma FA profile not only between sportsmen and sedentary subjects, but also between two groups of sportsmen. Plasma FA profile in basketball players showed significantly higher proportion of n-6 FA (20:3, 20:4, and 22:4) and total polyunsaturated FA (PUFA) than controls, while football players had higher palmitoleic acid (16:1) than basketball players and controls. Total PUFA and 22:4 were also higher in basketball than in football players. Erythrocyte FA profile showed no differences between football players and controls. However, basketball players had higher proportion of 18:0 than controls, higher saturated FA and lower 18:2 than two other groups, and higher 22:4 than football players. These findings suggest that long-term intensive exercise and type of sport influence FA profile.

    Full Text Available The place and importance of physical education in educational system is well known. Many researches have been done with the goal to determine influence of physical education on students. However, keep in mind that many of those researches had shown that women are generally not so interested in sports and that they are less included in physical activities (especially some forms of it, we have focused our work at possibilities of improvement of motoric abilities of girls inside chosen subject – sport for athletes, which is being conveyed in 8th grade with two classes per week, and chosen sport was basketball. Our sample consisted of 67 girls (37 in experimental and 30 in control group. Level of motoric abilities has been tracked by 14 test battery which measured levels of speed, coordination, precision, balance, flexibility and explosive strength. We concluded that subjects in experimental group improved levels of abilities in each test at final measuring. However, keep in mind that girls in control group had also show certain improvements in results of the t test for dependent samples at initial and final measurement of the following tests: horizontal wall bouncing for 15 seconds, hand and foot tapping, horizontal aiming and standing on one leg with eyes closed, we have compared by ANOVA measured results at final measurement of the each group. We concluded that there are statistically significant differences between groups in left hand basketball dribbling test, pull-through and jump-over tests, horizontal wall bouncing for 15 seconds, hand and foot tapping, standing on one leg with eyes closed, vertical jump – Sargent test, basketball throwing from chest from sitting position. Therefore, we can finally conclude that conveyed basketball programme had completely positive impact at motoric abilities of girls, as we expected

    Full Text Available The motivation of an athlete is determinant for the athletic engagement of the adolescent. The present study attempts to analyze the motivation of adolescent basketball and football players from the perspectives of Achievement Goal Theory (Nicholls, 1989 and Self-Determination Theory (Deci & Ryan, 1985. The study's sample was composed of 248 athletes from 12 to 17 years of age. Half were from basketball and half were from football. The instruments that were utilized were: the Spanish version of the Sport Motivation Scale (SMS (Núñez, Martín-Albo, Navarro, & González, 2006, the Spanish version of the Perceived Motivational Climate in Sport Questionnaire-2 (PMSCQ-2 (Balaguer, Mayo, Atienza, & Duda, 1997, and the adapted Spanish translation (Moreno, Moreno, & Cervelló, 2007 of the Intention to be Physically Active Scale (IPAS by Hein, Müür, and Koka (2004. The comparison of the means of the variables between football and basketball players was done utilizing the student t-test for independent samples. Significant differences were found for variables such as: intrinsic motivation (IM toward accomplishment, external regulation, amotivation, task, ego, and Self-Determination Index (SDI. Basketball players obtained higher values in the SDI, in task, and in IM toward accomplishment than football players. The search for premature performance in football and coaches' educations can help to explain these differences. The importance of these differences reside in the relationship between these motivational variables and the adherence to athletic practice. In conclusion, basketball demonstrated better values in motivational variables, which demonstrates that training sessions are more oriented toward task than ego, that players have more intrinsic and self-determined motivation, and therefore, the adherence of the young athletes will be greater in this sport.

    Full Text Available The relationships among physical characteristics, performance, and functional ability classification of younger wheelchair basketball players have been barely investigated to date. The purpose of this work was to assess anthropometry, body composition, and performance in sport-specific field tests in a national sample of Italian younger wheelchair basketball players as well as to evaluate the association of these variables with the players' functional ability classification and game-related statistics. Several anthropometric measurements were obtained for 52 out of 91 eligible players nationwide. Performance was assessed in seven sport-specific field tests (5m sprint, 20m sprint with ball, suicide, maximal pass, pass for accuracy, spot shot and lay-ups and game-related statistics (free-throw points scored per match, two- and three-point field-goals scored per match, and their sum. Association between variables, and predictivity was assessed by correlation and regression analysis, respectively. Players were grouped into four Classes of increasing functional ability (A-D. One-way ANOVA with Bonferroni's correction for multiple comparisons was used to assess differences between Classes. Sitting height and functional ability Class especially correlated with performance outcomes, but wheelchair basketball experience and skinfolds did not. Game-related statistics and sport-specific field-test scores all showed significant correlation with each other. Upper arm circumference and/or maximal pass and lay-ups test scores were able to explain 42 to 59% of variance in game-related statistics (P<0.001. A clear difference in performance was only found for functional ability Class A and D.In younger wheelchair basketball players, sitting height positively contributes to performance. The maximal pass and lay-ups test should be carefully considered in younger wheelchair basketball training plans. Functional ability Class reflects to a limited extent the actual

    The African-American-white mortality gap for males in the United States is 6 years in favor of whites. Participation in professional sport may moderate this ethnic disparity. The historical cohort of professional basketball players, with nearly equal numbers of African-American and white players, can provide a natural experiment that may control for the classic confounders of income, education, socioeconomic status (SES), and physical factors related to mortality. The objectives of this study are to assess mortality and calculate survival for the overall study population and within ethnicity. Data were combined from several publicly available sources. The cohort was analyzed to compare longevity among all players, and for players stratified by ethnicity, with the general U.S. population. The final dataset included 3366 individuals, of whom 56.0% were African American. Results suggest white players live 18 months longer than their African-American colleagues. African-American players gained 9 years on their respective referent and live longer than white men in the general public. After controlling for covariates, we found that African-American players have a 75% increased risk of death compared with white players, a statistically significant gap (p gap for males is largely ameliorated (1.5 years vs. 6.1 years) in professional basketball but still persists.

    The purpose of this study was to compare performance-based outcomes among professional athletes in four major North American sports following microfracture to treat symptomatic chondral defects of the knee. Major League Baseball (MLB), National Basketball Association (NBA), National Football League (NFL), and National Hockey League (NHL) athletes who underwent primary unilateral microfracture of the knee were identified through a previously reported protocol based on public sources. Successful return-to-play was defined as returning for at least one professional regular season game after surgery. Regular season player statistics and sport-specific performance scores were compiled for each player. Each player served as his own control, with the season prior to surgery defined as baseline. Comparisons across sports were enabled by adjusting for expected season and career length differences between sports and by calculating percent changes in performance. One hundred thirty one professional athletes who underwent microfracture were included. One hundred three athletes (78.6%) successfully returned to play. The ratio of games started-to-games played before surgery was found to be a significant positive independent predictor of returning (p = 0.002). Compared with their preoperative season, basketball and baseball players demonstrated significantly decreased performance one season after surgery (-14.8%, p = 0.029 and -12.9%, p = 0.002, respectively) that was recoverable to baseline by postoperative seasons 2-3 for baseball players but not for basketball players (-9.7%, p = 0.024). Knee microfracture surgery is associated with a high rate of return to the professional level. However, the impact of this procedure on postoperative performance varied significantly depending on sport. Copyright © 2018. Published by Elsevier B.V.

    Full Text Available South Asian American participants of a co-ethnic basketball league, known as Indo-Pak Basketball, utilized urban basketball vernacular through the phrase “liting it up” to identify individuals scoring points in great numbers. The person “liting it up” becomes visible and receives recognition. Accordingly, I want to “lite up” the scholarship on South Asian America whereby situating South Asian American religious sites and cultural centers as key arenas for “Americanization” through US popular culture. I situate sport as a key element of popular culture through which South Asian American communities work out, struggle through, and contest notions of self. Informed by an Anthropology of Sport, ethnography of South Asian American communities in Atlanta takes place alongside an examination of the North American Indo-Pak Basketball circuit. Accordingly, my findings indicate that such community formation has also taken shape at the intersections of institutions, gender, and sexuality whereby excluding queers, women, and other communities of color.

    The purpose of this study was to determine if a sports-specific training program could improve neuromuscular and performance indices in female high school basketball players. We combined components from a published anterior cruciate ligament injury prevention program for jump and strength training with other exercises and drills to improve speed, agility, overall strength, and aerobic conditioning. We hypothesized that this sports-specific training program would lead to significant improvements in neuromuscular and performance indices in high school female basketball players. Fifty-seven female athletes aged 14-17 years participated in the supervised 6-week program, 3 d·wk(-1) for approximately 90-120 minutes per session. The program was conducted on the basketball court and in weight room facilities in high schools. The athletes underwent a video drop-jump test, multistage fitness test, vertical jump test, and an 18-m sprint test before and upon completion of the training program. All the subjects attended at least 14 training sessions. After training, a significant increase was found in the mean estimated VO2max (p basketball players.

    A graded shuttle run test was used to assess differences in physiological parameters between playing positions in elite female basketball players. Twenty-four female basketball players (8 guards, 8 forwards, and 8 centers) who played for the senior national teams of Slovenia and Serbia were tested with the 30-15 intermittent fitness test. During the shuttle run, the following physiological parameters were measured: oxygen consumption ((Equation is included in full-text article.)), carbon dioxide production ((Equation is included in full-text article.)), pulmonary ventilation (VE) breath by breath, respiratory quotient, oxygen pulse as the (Equation is included in full-text article.)vs. HR ratio and [LA]. No significant differences were found for any of the measures between the 3 playing positions. Although this finding was surprising, future studies should try to determine whether the tactics used in female basketball determine that the interpositional differences seen in male basketball are not evident.

    Full Text Available The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants performed 10 repetitions of the following sequence: Abalakov jump, Change-of-Direction and Acceleration Test (CODAT and two free throws. Later, heart rate, body impacts and game statistics were recorded during a 20-min simulated basketball game. In comparison to the placebo, the ingestion of caffeine increased mean jump height (37.3 ± 6.8 vs. 38.2 ± 7.4 cm; p = 0.012, but did not change mean time in the CODAT test or accuracy in free throws. During the simulated game, caffeine increased the number of body impacts (396 ± 43 vs. 410 ± 41 impacts/min; p < 0.001 without modifying mean or peak heart rate. Caffeine also increased the performance index rating (7.2 ± 8.6 vs. 10.6 ± 7.1; p = 0.037 during the game. Nevertheless, players showed a higher prevalence of insomnia (19.0 vs. 54.4%; p = 0.041 after the game. Three mg of caffeine per kg of body mass could be an effective ergogenic substance to increase physical performance and overall success in experienced basketball players.

    Injury patterns in elite athletes over long periods continue to evolve. The goal of this study was to review of the injuries and medical conditions afflicting athletes competing in the National Basketball Association (NBA) over a 17-year period. Descriptive epidemiological study. Injuries and player demographic information were reported by each team's athletic trainer. Criteria for reportable injuries were those that resulted in (1) physician referral, (2) a practice or game being missed, or (3) emergency care. The demographics, frequency of injury, time lost, and game exposures were tabulated, and game-related injury rates and 95% confidence intervals were calculated. A total of 1094 players appeared in the database 3843 times (3.3 ± 2.6 seasons). Lateral ankle sprains were the most frequent orthopaedic injury (n, 1658; 13.2%), followed by patellofemoral inflammation (n, 1493; 11.9%), lumbar strains (n, 999; 7.9%), and hamstring strains (n, 413; 3.3%). The most games missed were related to patellofemoral inflammation (n, 10 370; 17.5%), lateral ankle sprains (n, 5223; 8.8%), knee sprains (n, 4369; 7.4%), and lumbar strains (n, 3933; 6.6%). No correlations were found between injury rate and player demographics, including age, height, weight, and NBA experience. Professional athletes in the NBA experience a high rate of game-related injuries. Patellofemoral inflammation is the most significant problem in terms of days lost in competition, whereas ankle sprains are the most common injury. True ligamentous injuries of the knee were surprisingly rare. Importantly, player demographics were not correlated with injury rates. Further investigation is necessary regarding the consequences and sport-specific treatment of various injuries in NBA players. Knowledge of these injury patterns can help to guide treatments and provide more accurate guidelines for an athlete to return to play.

    2011-12-01

    Patellar tendinopathy (PT) is one of the most common reasons for sport-induced pain of the knee. Low ankle dorsiflexion range might predispose for PT because of load-bearing compensation in the patellar tendon. The purpose of this 1-year prospective study was to analyze if a low ankle dorsiflexion range increases the risk of developing PT for basketball players. Cohort study (prognosis); Level of evidence, 2. Ninety junior elite basketball players were examined for different characteristics and potential risk factors for PT, including ankle dorsiflexion range in the dominant and nondominant leg. Data were collected over a 1-year period and follow-up, including reexamination, was made at the end of the year. Seventy-five players met the inclusion criteria. At the follow-up, 12 players (16.0%) had developed unilateral PT. These players were found to have had a significantly lower mean ankle dorsiflexion range at baseline than the healthy players, with a mean difference of -4.7° (P = .038) for the dominant limb and -5.1° (P = .024) for the nondominant limb. Complementary statistical analysis showed that players with dorsiflexion range less than 36.5° had a risk of 18.5% to 29.4% of developing PT within a year, as compared with 1.8% to 2.1% for players with dorsiflexion range greater than 36.5°. Limbs with a history of 2 or more ankle sprains had a slightly less mean ankle dorsiflexion range compared to those with 0 or 1 sprain (mean difference, -1.5° to -2.5°), although this was only statistically significant for nondominant legs. This study clearly shows that low ankle dorsiflexion range is a risk factor for developing PT in basketball players. In the studied material, an ankle dorsiflexion range of 36.5° was found to be the most appropriate cutoff point for prognostic screening. This might be useful information in identifying at-risk individuals in basketball teams and enabling preventive actions. A history of ankle sprains might contribute to reduced ankle

    2012-05-01

    Full Text Available Abstract Background Basketball is the second most popular sport in Nigeria after football and is commonly played by adolescents. Prospective studies on adolescent basketball players in Nigeria are lacking. Such studies will help to develop injury counter-measures. Hence, this study aimed at determining the incidence and pattern of injuries among adolescent basketball players in Nigeria. Methods A prospective observational study involving 141 adolescent basketball players (75 boys and 66 girls; with age range 15 – 18 years who participated in the 2010 National Finals of the Nigeria Nestlé Milo Basketball Competition. Basketball-related injury data were collected by an assessor during the competition using a standardized basketball injury report form. Data were analyzed using descriptive and inferential statistics. Results A total of 32 injuries were recorded with an incidence of 22.7 injuries per 100 participants same for boys and girls. This is equivalent to 1.1 injury per match for boys and 0.9 injuries per match for girls. Jumping/landing was the most common cause of injury (28.1%, N = 9. Most of the injuries were at the lower extremities (75%, N = 24; with majority at the knee joint (40.6%, N = 13. Ligament sprain was the most common types of injury. The pattern of injuries among boys did not significantly differ from that of girls (P > 0.05. Most injuries (N = 13, 41% occurred in the offensive half of the court and cryotherapy was the most frequently used treatment modality. Conclusion The overall incidence of match injury among adolescent amateur basketball players during a national competition in Nigeria was 22.7 injuries per 100 participants; equivalence of 1.0 injury per match. The pattern of injuries was similar in both genders and consistent with what has been previously reported in literature for adolescent basketball players. Exercise-based injury prevention programmes aimed at improving core strength and

    Anterior cruciate ligament (ACL) injuries are significant injuries in elite-level basketball players. In-game statistical performance after ACL reconstruction has been demonstrated; however, few studies have reviewed functional performance in National Basketball Association (NBA)-caliber athletes after ACL reconstruction. To compare NBA Combine performance of athletes after ACL reconstruction with an age-, size-, and position-matched control group of players with no previous reported knee injury requiring surgery. We hypothesized that there is no difference between the 2 groups in functional performance. Cross-sectional study; Level of evidence, 3. A total of 1092 NBA-caliber players who participated in the NBA Combine between 2000 and 2015 were reviewed. Twenty-one athletes were identified as having primary ACL reconstruction prior to participation in the combine. This study group was compared with an age-, size-, and position-matched control group in objective functional performance testing, including the shuttle run test, lane agility test, three-quarter court sprint, vertical jump (no step), and maximum vertical jump (running start). With regard to quickness and agility, both ACL-reconstructed athletes and controls scored an average of 11.5 seconds in the lane agility test and 3.1 seconds in the shuttle run test (P = .745 and .346, respectively). Speed and acceleration was measured by the three-quarter court sprint, in which both the study group and the control group averaged 3.3 seconds (P = .516). In the maximum vertical jump, which demonstrates an athlete's jumping ability with a running start, the ACL reconstruction group had an average height of 33.6 inches while the controls averaged 33.9 inches (P = .548). In the standing vertical jump, the ACL reconstruction group averaged 28.2 inches while the control group averaged 29.2 inches (P = .067). In athletes who are able to return to sport and compete at a high level such as the NBA Combine, there is no

    Full Text Available Introduction: Osgood–Schlatter disease is an irritation of the patellar tendon at the tibial tubercle. Sports with jumps, running, and repeated contractions of knee extension apparatus are considered to be importantexternal risk-factors which could cause Osgood–Schlatter disease.Objectives of the study are to draw attention to the importance of clinical examination in diagnostics of Osgood–Schlatter disease in boys playing soccer or basketball.Methods: The research included data obtained from 120 boys, average age of 14 years. Examinees were split into two groups, one with young athletes which regularly have soccer or basketball trainings and thesecond one with boys who do not participating in sports. We performed anthropological measurements and clinical examinations of both knees and hips for both groups. For the statistical analysis we used pointbiserialcorrelation coefficient.Results: Based on clinical examination, Osgood–Schlatter disease was diagnosed in 51 examinees (42.5%. In “athletic group” Osgood–Schlatter disease had 31 boys or 52%, comparing with “non-athletic group” wherewe found 20 adolescents with disease (33%. Number of boys with Osgood–Schlatter disease was higher for 19% in “athletic group” comparing with “non-athletic group”. Comparing incidence rate for boys in both groups with diagnosed II and III level of Osgood–Schlatter disease we found that rate is higher in “athletic group” 2.25 times comparing with “non-athletic group”.Conclusions: Clinical examination is critical method in the process of diagnosing Osgood–Schlatter disease especially for identifying II and III level of this disease.

  14. Drawing disability in Japanese manga: visual politics, embodied masculinity, and wheelchair basketball in Inoue Takehiko's REAL.

    Science.gov (United States)

    Wood, Andrea

    2013-12-01

    This work explores disability in the cultural context of contemporary Japanese comics. In contrast to Western comics, Japanese manga have permeated the social fabric of Japan to the extent that vast numbers of people read manga on a daily basis. It has, in fact, become such a popular medium for visual communication that the Japanese government and education systems utilize manga as a social acculturation and teaching tool. This multibillion dollar industry is incredibly diverse, and one particularly popular genre is sports manga. However, Inoue Takehiko's award-winning manga series REAL departs from more conventional sports manga, which typically focus on able-bodied characters with sometimes exaggerated superhuman physical abilities, by adopting a more realistic approach to the world of wheelchair basketball and the people who play it. At the same time REAL explores cultural attitudes toward disability in Japanese culture-where disability is at times rendered "invisible" either through accessibility problems or lingering associations of disability and shame. It is therefore extremely significant that manga, a visual medium, is rendering disability visible-the ultimate movement from margin to center. REAL devotes considerable attention to realistically illustrating the lived experiences of its characters both on and off the court. Consequently, the series not only educates readers about wheelchair basketball but also provides compelling insight into Japanese cultural notions about masculinity, family, responsibility, and identity. The basketball players-at first marginalized by their disability-join together in the unity of a sport typically characterized by its "abledness."

    Full Text Available The Olympic Games is the pinnacle international sporting competition with team sport coaches interested in key performance indicators to assist the development of match strategies for success. This study examined the relationship between team performance indicators and match outcome during the women’s basketball tournament at the Olympic Games. Team performance indicators were collated from all women’s basketball matches during the 2004–2016 Olympic Games (n = 156 and analyzed via linear (binary logistic regression and non-linear (conditional interference (CI classification tree statistical techniques. The most parsimonious linear model retained “defensive rebounds”, “field-goal percentage”, “offensive rebounds”, “fouls”, “steals”, and “turnovers” with a classification accuracy of 85.6%. The CI classification tree retained four performance indicators with a classification accuracy of 86.2%. The combination of “field-goal percentage”, “defensive rebounds”, “steals”, and “turnovers” provided the greatest probability of winning (91.1%, while a combination of “field-goal percentage”, “steals”, and “turnovers” provided the greatest probability of losing (96.7%. Shooting proficiency and defensive actions were identified as key team performance indicators for Olympic female basketball success. The development of key defensive strategies and/or the selection of athletes highly proficient in defensive actions may strengthen Olympic match success. Incorporation of non-linear analyses may provide teams with superior/practical approaches for elite sporting success.

    2014-01-01

    Background An estimated 30 to 40 million school children participate in sports in the United States; 34% of middle-school participants become injured and seek medical treatment at an annual cost close to $2 billion. The purpose of the current study was to evaluate the injury incidence and rates in female athletes in the middle-school setting during the course of 3 seasons. Methods Female basketball, soccer, and volleyball players were recruited from a single county public school district in Kentucky consisting of 5 middle schools. A total of 268 female athletes (162 basketball, 26 soccer, and 80 volleyball) participated. Athletes were monitored for sports-related injury and number of athlete exposures (AEs) by an athletic trainer. Injury rates were calculated for specific types of injuries within each sport. Injury rates for games and practices were also calculated and compared for each sport. Results A total of 134 injuries were recorded during the 3 sport seasons. The knee was the most commonly injured body part (99 injuries [73.9%]), of which patellofemoral dysfunction (31.3%), Osgood-Schlatter disease (10.4%), and Sinding-Larsen-Johansson/patella tendinosis (9%) had the greatest incidence. The ankle was the second most commonly injured body part, accounting for 16.4% of all injuries. The overall rates of injury by sport were as follows: soccer, 6.66 per 1000 AEs; volleyball, 3.68 per 1000 AEs; and basketball, 2.86 per 1000 AEs. Conclusions Female middle-school athletes displayed comparable injury patterns to those seen in their high-school counterparts. Future work is warranted to determine the potential for improved outcomes in female middle-school athletes with access to athletic training services. Clinical Relevance As the participation levels and number of injuries continue to rise, middle-school athletes demonstrate an increasing need for medical services provided by a certified athletic trainer.

    Fox, JL, Scanlan, AT, and Stanton, R. A review of player monitoring approaches in basketball: current trends and future directions. J Strength Cond Res 31(7): 2021-2029, 2017-Effective monitoring of players in team sports such as basketball requires an understanding of the external demands and internal responses, as they relate to training phases and competition. Monitoring of external demands and internal responses allows coaching staff to determine the dose-response associated with the imposed training load (TL), and subsequently, if players are adequately prepared for competition. This review discusses measures reported in the literature for monitoring the external demands and internal responses of basketball players during training and competition. The external demands of training and competition were primarily monitored using time-motion analysis, with limited use of microtechnology being reported. Internal responses during training were typically measured using hematological markers, heart rate, various TL models, and perceptual responses such as rating of perceived exertion (RPE). Heart rate was the most commonly reported indicator of internal responses during competition with limited reporting of hematological markers or RPE. These findings show a large discrepancy between the reporting of external and internal measures and training and competition demands. Microsensors, however, may be a practical and convenient method of player monitoring in basketball to overcome the limitations associated with current approaches while allowing for external demands and internal responses to be recorded simultaneously. The triaxial accelerometers of microsensors seem well suited for basketball and warrant validation to definitively determine their place in the monitoring of basketball players. Coaching staff should make use of this technology by tracking individual player responses across the annual plan and using real-time monitoring to minimize factors such as fatigue

    Full Text Available In wheelchair sports, aerobic performance is commonly assessed with the use of an arm crank ergometer (ACE, a wheelchair ergometer (WCE or a wheelchair treadmill (WCT. There are different protocols to identify peak oxygen uptake in wheelchair sports; however, only a few protocols have been applied to evaluate these conditions in wheelchair basketball players. The purpose of this study was to compare physiological responses during maximal exercise testing with the use of ACE and WCT in wheelchair basketball players. Twelve elite male wheelchair basketball players participated in this study. The research was performed during a training camp of the Polish National Wheelchair Basketball Team. The study participants were divided into two functional categories: A (players with class 1.0 - 2.5 and B (players with class 3.0 - 4.5. Two main maximal exercise tests, i.e. wheelchair treadmill stress test (WCT test and arm crank ergometer stress test (ACE test were used to evaluate aerobic performance of the players. There were no statistically significant differences in aerobic tests between the players from both groups. The comparison of results achieved in two aerobic tests performed on WCT and ACE did not reveal any significant differences between the analyzed variables (peak heart rate (HRpeak, peak oxygen uptake (VO2peak, minute ventilation (VE, anaerobic threshold (AT, lactate concentration (LApeak, and a drop in lactate concentration (%LA. Strong correlations between results achieved in WCT and ACE tests were found for VO2peak, VE and LApeak. The main conclusion of the study is that both WCT and ACE tests may be useful when determining aerobic capacity of wheelchair basketball players. Moreover, both protocols can be used by athletes regardless of their functional capabilities and types of impairment.

    Full Text Available In general the problematic of diagnosing basic and specific motor movement information of the basketball game in found in the works of a considerable number of world authors. In this work a youth population of an age group between 13-14 years old will be treated. The total number of participants is defined to an amount of 100 of young basketball players, members of two different basketball academies. In this experiment, the subjects will conduct tests in 5 basic motor skills variables such as: 1. Steady Jump in length, 2 steady jump in height 3.20 meters run from a steady start, 4. Medicine Ball Throw and 5. Agility Test. While from specific motor movement skills are included: 1.20 Meters run with ball, 2. Basketball shooting for 30 seconds round-trip,3. Anaerobic durability with and without ball (kamikaze 4. Intensive Basketball shots-Change of direction and 5. Basketball shots from five positions. Subject to the number of subjects that will be treated in this study, their age and the amount of variables tested, the main objectives of this study, will be limited to achieving the goals. On the basis of test results, it can be concluded that there are no significant differences in the basic motor parameters between the two groups G1 and G2, mostly due to systematic practice effects rather than academy belonging itself.In the other hand, differences between the two groups in the specific basketball motor skills can be clearly identified, in typical basketball movement situations.In addition, comparing the test results of the individuals tested for the purpose if this diagnosis, a much more advanced level of motor skills compared to the normal population of the same group age that don’t engage in basketball activities can be identified. This experimental study carried out in the youth in the age group of 13(-+ 6 months years old that continuously in a systematic manner attend basketball academies in two different basketball schools, with

    Vitamin D plays an important role in several systems of the human body. Various studies have linked vitamin D deficiency to stress and insufficiency fractures, muscle recovery and function, and athletic performance. The prevalence of vitamin D deficiency in the elite athletic population has not been extensively studied, and very few reports exist among professional athletes. There is a high prevalence of vitamin D deficiency or insufficiency among players attending the National Basketball Association (NBA) Combine. Cross-sectional study; Level of evidence, 3. This is a retrospective review of data previously collected as part of the routine medical evaluation of players in the NBA Combines from 2009 through 2013. Player parameters evaluated were height, weight, body mass index (BMI), and vitamin D level. Statistical analysis using t tests and analysis of variance was used to detect any correlation between the player parameters and vitamin D level. Vitamin D levels were categorized as deficient (32 ng/mL). After institutional review board approval was submitted to the NBA, the NBA released deidentified data on 279 players who participated in the combines from 2009 through 2013. There were 90 players (32.3%) who were deficient, 131 players (47.0%) who were insufficient, and 58 players (20.8%) who were sufficient. A total of 221 players (79.3%) were either vitamin D deficient or insufficient. Among all players included, the average vitamin D level was 25.6 ± 10.2 ng/mL. Among the players who were deficient, insufficient, and sufficient, the average vitamin D levels were 16.1 ± 2.1 ng/mL, 25.0 ± 3.4 ng/mL, and 41.6 ± 8.6 ng/mL, respectively. Player height and weight were significantly increased in vitamin D-sufficient players compared with players who were not sufficient (P = .0008 and .009, respectively). Player age and BMI did not significantly differ depending on vitamin D status (P = .15 and .77, respectively). There is a high prevalence of vitamin D deficiency

    Although injuries related to sports and recreation represent a significant burden to children and youth, few studies have examined the descriptive epidemiology of sports-related injury since 2005, and some sports such as ringette have not been evaluated to date. The primary purpose of this study was to provide the descriptive epidemiology of sports-related injuries treated in emergency departments for children and youth aged 5 - 19. A retrospective data analysis was performed using data from the Canadian Hospitals Injury Reporting and Prevention Program [CHIRPP] from fiscal years (April - March) 2007/08 to 2009/10. CHIRPP is a computerized information system designed by the Public Health Agency of Canada that collects information about injuries to people evaluated in emergency departments across 11 pediatric hospitals and 5 general hospitals in Canada. Thirteen sports or activities were analyzed (baseball, basketball, cycling, football, ice hockey, lacrosse, ringette, rugby, skiing, sledding, snowboarding, soccer, and volleyball). Descriptive statistics, including frequency by sport, age and sex, as well as the percent of concussions within each sport were calculated. Out of a total of 56, 691 reported sports and recreational injuries, soccer accounted for the largest proportion of injuries with 11,941 reported cases over the 3 year time period. Of these, approximately 30% were fractures. The 10 - 14 year age group reported the greatest proportion of injuries in 10 out of the 13 sports analyzed. In addition, males reported a greater number of overall injuries than females in 11 out of the 13 sports analyzed. The largest percentage of concussions was reported in ringette; these injuries accounted for 17.1% of overall injuries within this sport. Injury prevention programs in Canada should focus on improving evidence-based programs to reduce the burden of injuries in all sports.

    Patellar tendinopathy (PT) has a multifactorial etiology, and many possible risk factors have been described in the literature. The findings are conflicting, though, and most research has been conducted on elite athletes. The aim of the current study is to determine the risk factors for PT in a large representative sample of basketball and volleyball players. Separate risk factors for men and women, basketball and volleyball players, and athletes with unilateral and bilateral PT were identified. All basketball and volleyball players between ages 18 and 35 from the Dutch Basketball Association and the Dutch Volleyball Association were invited to complete an online questionnaire on knee complaints and risk factors for PT. The logistic regression analyses included 2224 subjects. The risk factors for PT were age, playing at the national level, being male and playing volleyball (compared with playing basketball). The risk factors for men and women were comparable. Among volleyball players, outside hitters and middle blockers/hitters had an increased risk compared with setters. For basketball players, no risk factors could be identified. No differences in the risk factors were found between athletes with unilateral and bilateral PT. These findings should be taken into account for prevention and rehabilitation purposes. © 2011 John Wiley & Sons A/S.

    Male factor infertility plays a significant role in infertility. Many factors have been associated with male infertility; however, the link between many sports and recreational factors and male reproduction remains poorly characterized. To evaluate the current literature regarding the impact of many common sports and recreational factors on male reproduction. A comprehensive PubMed and Embase search for relevant articles published between 1970 and 2017 was performed by combining the following search terms: male, sports (including individual sports), traumatic brain injury, sauna, hot tub, fertility, erectile dysfunction, varicocele, environment, cell phone, and laptop computer. Hypogonadism and erectile dysfunction can be associated with sports with high rates of head injuries, such as American football. Although early reports linked other sports, such as bicycling, to erectile dysfunction, subsequent studies isolated these associations to sports cycling rather than recreational cycling. Certain sports (football, basketball, handball, and volleyball) were linked to increasing prevalence and severity of varicocele, offering a potential link to male infertility. In addition, recreational activities such as sauna, hot tubs, Jacuzzis, heated car seats, and laptop use were associated with high testicular temperature, which can impair spermatogenesis. Radio frequency electromagnetic waves from cell phones and laptops have also been shown to have deleterious effects on sperm viability and motility. Many common sports and daily activities represent potential sources of male infertility. Clinicians should be aware of these associations in explaining idiopathic infertility in males. Male infertility is an often overlooked component of a couple's inability to conceive. We outline many common and often overlooked sports and recreational exposures that have been associated with male infertility. Copyright © 2018 European Association of Urology.

    Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

    2017-08-01

    Full Text Available Basketball is a sports discipline in which the ankle sprain is the most common injury. It is considered to be an aggravated activity by its dimension of teamwork, contact and requiring a variety of motion dynamics. The aim of this paper is to identify basketball game elements that contribute to the development of traumatic torsion injuries, to present methods of injury prevention and to present possible methods for the rehabilitation of athletes in different stages of injury healing. A sprain and a torsion of the ankle is not a traumatic event defined at one time, but is often a cycle of repetitive trauma. It is also important to educate competitors not to underestimate these types of injuries and to treat them with serious medical and rehabilitation procedures. Rehabilitation of the ankle joint is dependent on the degree of injury, and above all on the extent of the damaged tissue. In order to avoid trauma, proprioception and global stabilization training play a very important role. Unstable ankle instability is associated with serious complications.

    Full Text Available The basketball is a complex sport, which these days has become increasingly linked to its’ psychophysical aspects rather than to the technical ones. Therefore, it is important to make a through study of the passing techniques from the point of view of the type of the pass and its’ biomechanics. From the point of view of the type of the used passes, the most used is the two-handed chest pass with a frequency of 39.9%. This is followed, in terms of frequency, by one-handed passes – the baseball, with 20.9 % – and by the two-handed over the head pass, with 18.2 %, and finally, one- or two-handed indirect passes (bounces, with 11.2 % and 9.8 %. Considering the most used pass in basketball, from the biomechanical point of view, the muscles involved in the correct movement consider all the muscles of the upper extremity, adding also the shoulder muscles as well as the body fixators (abdominals, hip flexors, knee extensors, and dorsal flexors of the foot. The technical and conditional analysis considers the throwing speed, the throw height and the air resistance. In conclusion, the aim of this study is to give some guidelines to improve the mechanical execution of the movements in training, without neglecting the importance of the harmony of the movements themselves.

    Full Text Available Participation in organised, competitive physical activity by young athletes is increasing rapidly. This is concurrent with an increase in sporting injuries in the young population. This pilot study aimed to compare the weekly volume and types of physical activity in young basketball players injured and not injured during the season. Detailed physical activity and injury data were prospectively collected in 46 school-level basketball players aged 14 to 18 years. Participants completed physical activity logs which documented the type of physical activity undertaken, what the activity consisted of (i.e. training, competition and the level at which it was played on a daily basis. Allied health staff completed a weekly injury form. Results showed that injured and uninjured athletes participated in a similar volume of total weekly physical activity over the season. However, injured athletes (p = 0.04 and athletes who specifically sustained overuse injuries (p = 0.01 participated in a greater amount of basketball refereeing than uninjured athletes. Based on these findings it was concluded that greater participation in running-type physical activity such as refereeing, as an addition to training and competition, may predispose the young basketball player to increased injury risk. Future research using larger sample sizes are required to further investigate the role of participation volume and type on injury occurrence in adolescent athletes

    We investigated knee functions and a return to sports in 50 competitive athlete patients treated with arthroscopic anterior cruciate ligament reconstruction using double-looped STG augmented by woven polyester at a 1-year follow-up. There were 25 males and 25 females with a mean age of 24.3 years (range: 19-39 years). The majority of preinjury sports were basketball, volleyball and soccer. Athletic rehabilitation including agility training and sports-specific training was started at 12 weeks. Fourty patients (80%) was rated as normal or nearly normal on the assessment of International Knee Documentation Commitee postoperatively. Fourty-eight patients (96%) obtained full range of motion, and the mean quadriceps muscle strength of the injured side was 91.3%of that of the uninjured side. As for a return to sports, 46 patients (92%) were able to do fully competitive sports at a mean of 8.1 postoperative months. These results suggest that arthroscopic reconstruction using augmented double-looped STG allows early athletic rehabilitation, and lead satisfactory outcome as well as a reliable and early return to preinjury level of sport activity for the majority of the competitive athlete patients.

    Full Text Available The purpose of our research was to investigate the relative frequencies of different types of basketball shots (above head, hook shot, layup, dunk, tip-in, some details about their technical execution (one-legged, two-legged, drive, cut, …, and shot success in different levels of basketball competitions. We analysed video footage and categorized 5024 basketball shots from 40 basketball games and 5 different levels of competitive basketball (National Basketball Association (NBA, Euroleague, Slovenian 1st Division, and two Youth basketball competitions. Statistical analysis with hierarchical multinomial logistic regression models reveals that there are substantial differences between competitions. However, most differences decrease or disappear entirely after we adjust for differences in situations that arise in different competitions (shot location, player type, and attacks in transition. Differences after adjustment are mostly between the Senior and Youth competitions: more shots executed jumping or standing on one leg, more uncategorised shot types, and more dribbling or cutting to the basket in the Youth competitions, which can all be attributed to lesser technical and physical ability of developing basketball players. The two discernible differences within the Senior competitions are that, in the NBA, dunks are more frequent and hook shots are less frequent compared to European basketball, which can be attributed to better athleticism of NBA players. The effect situational variables have on shot types and shot success are found to be very similar for all competitions.

    Medical expenses for collegiate athletics include providing a training room with its supplies, equipment, personnel costs, and insurance coverage. Additional expenses beyond the training room include imaging, diagnostic testing, specialty consultations, and surgeries. We hypothesized that there would be no difference in average expenses or number of claims between male and female athletes over a 5-year period. Prospective patient cohort. A sports medicine center serving athletes in Big 10 Conference intercollegiate sports. All medical claims and charges for 36 varsity teams were analyzed from 2005 to 2010. The teams were categorized into 3 groups: female-only teams, male-only teams, and coed teams. Analysis of sports with corresponding male and female teams was also performed. Claims and charges for medical care for 36 intercollegiate athletic teams over 5 years. Individual team claims and charges were stable over the study period. In 11 of the 14 sex-matched sports, the female teams had higher average annual charges. After normalizing for roster size in the sex-matched sports, females had 0.97 more average annual claims (P sports with the highest average annual charges per athlete were softball, women's diving, men's basketball, wrestling, and men's gymnastics. Charges per claim were similar between the sex-matched sports, but the female sports had a higher number of annual claims per athlete and thus higher total charges per athlete/year. Football had the highest average annual total charges as a team, but when normalized for roster size football charges per athlete/year were similar to those of other sports.

    The incidence of sudden cardiac death is higher in US basketball players compared with other athlete groups. However, the recognition of the risk for sudden cardiac death among basketball players is challenging because little is known regarding athletic cardiac remodeling in these athletes or athletes of similarly increased size. To perform a comprehensive cardiac structural analysis of National Basketball Association (NBA) professional athletes. Echocardiographic observational study of NBA players on the active rosters for the 2013-2014 and 2014-2015 seasons was performed from December 16, 2013, to December 12, 2014. The policy of the NBA mandates annual preseason stress echocardiograms for each player. The NBA has sanctioned Columbia University Medical Center to conduct annual health and safety reviews of these echocardiograms. Data were analyzed from January to May 2015. Cardiac variables assessed included left ventricular (LV) size, mass, wall thickness, and hypertrophy patterns and function; left atrial volume; and aortic root diameter. All dimensions were biometrically scaled. Of the 526 athletes included in the study, 406 (77.2%) were African American and 107 (20.3%) were white, with a mean (SD) age of 25.7 (4.3) years. Mean (SD) athlete height was 200.2 (8.8) cm; mean body surface area, 2.38 (0.19) m2. Left ventricular size and mass in NBA athletes were proportional to body size, extending to the uppermost biometrics of the cohort. Left ventricular hypertrophy was present in 144 athletes (27.4%). African American athletes had increased LV wall thickness (unadjusted mean, 11.2 mm; 95% CI, 11.1-11.3 mm) and LV mass (unadjusted mean, 106.3 g/m2; 95% CI, 104.6-108.0 g/m2) compared with LV wall thickness (unadjusted mean, 10.5 mm; 95% CI, 10.3-10.7 mm; P basketball players and the athletic community at large.

    Objective To investigate the physiological and perceptual effects of three precooling strategies during pre-exercise rest in athletes with a spinal cord injury (SCI). Design Randomized, counterbalanced. Participants were precooled, then rested for 60 minutes (22.7 ± 0.2°C, 64.2 ± 2.6%RH). Setting National Wheelchair Basketball Training Centre, Australia. Participants Sixteen wheelchair basketball athletes with a SCI. Interventions Participants were precooled through; 1) 10 minutes of 15.8°C cold water immersion (CWI), 2) ingestion of 6.8 g/kg−1 of slushie (S) from sports drink; 3) ingestion of 6.8 g/kg−1 of slushie with application of iced towels to the legs, torso and back/arms (ST); or 4) ingestion of 6.8 g/kg−1 of room temperature (22.3°C) sports drink (CON). Outcome measures Core temperature (Tgi), skin temperature (Tsk), heart rate (HR), and thermal and gastrointestinal comfort. Results Following CWI, a significant reduction in Tgi was observed compared to CON, with a greatest reduction of 1.58°C occurring 40 minutes post-cooling (95% CI [1.07, 2.10]). A significant reduction in Tgi following ST compared to CON was also observed at 20 minutes (0.56°C; [0.03, 1.09]) and 30 minutes (0.56°C; [0.04, 1.09]) post-cooling. Additionally, a significant interaction between impairment level and time was observed for Tgi and HR, demonstrating athletes with a higher level of impairment experienced a greater reduction in HR and significant decrease in rate of decline in Tgi, compared to lesser impaired athletes. Conclusion CWI and ST can effectively lower body temperature in athletes with a SCI, and may assist in tolerating warm conditions. PMID:27192132

    The aims of this study were to determine the effects of (a) plyometric training on explosive strength indicators in adolescent male basketball players and (b) detraining and reduced training on previously achieved explosive strength gains. Two groups were formed: an experimental and a control group. The former was submitted to a 10-week in-season plyometric training program, twice weekly, along with regular basketball practice. Simultaneously, the control group participated in regular basketball practice only. At the end of this period, the experimental group was subdivided into 2 groups: a reduced training group and a detraining group. All participants were assessed on squat jump, countermovement jump, Abalakov test, depth jump, mechanical power, and medicine ball throw at the beginning and at the end of the 10-week in-season plyometric training and on weeks 4, 8, 12, and 16 of the in-season detraining and reduced training periods. In the first phase of the study, the experimental group significantly increased all the assessed indicators (p training showed positive effects on upper- and lower-body explosive strength in adolescent male basketball players. Moreover, we can state that both detraining and a reduced training program indistinctly contribute to maintenance of strength levels. These results highlight the unique power that basketball-specific training seems to have on the sustainability and maintenance of sport performance.

    Injuries are inherent in basketball with lower extremity (LE) injury rates reported as high as 11.6 per 1000 athletic exposures (AEs); many of these injuries result in time loss from sport participation. A recent trend in sports medicine research has been the attempt to identify athletes who may be at risk for injury based on measures of preseason fitness. The purpose of this prospective cohort study was to determine if the standing long jump (SLJ) and/or the single-leg hop (SLH) for distance functional performance tests (FPT) are associated with non-contact time loss lower quadrant (LQ, defined as lower extremities or low back) injury in collegiate male basketball players. It was hypothesized that basketball players with shorter SLJ or SLH measures would be at an increased risk for LQ injury. Seventy-one male collegiate basketball players from five teams completed a demographic questionnaire and performed three SLJ and six SLH (three per lower extremity) tests. Team athletic trainers tracked non-contact LQ time loss injuries during the season. Prospective cohort. Mean SLJ distance (normalized to height) was 0.99 (± 0.11) and mean SLH distances for the right and left were 0.85 ± 0.11 and 0.87 ± 0.10, respectively. A total of 29 (18 initial, 11 subsequent) non-contact time loss LQ injuries occurred during the study. At risk athletes (e.g., those with shorter SLJ and/or SLH) were no more likely to experience a non-contact time loss injury than their counterparts [OR associated with each FPT below cut scores = 0.9 (95% CI: 0.2, 4.9)]. The results from this study indicate that preseason performance of the SLJ and the SLH were not associated with future risk of LQ injury in this population. Preseason SLJ and SLH measures were not associated with non-contact time loss injuries in male collegiate basketball players. However, the descriptive data presented in this study can help sports medicine professionals evaluate athletic readiness prior to discharging

    Full Text Available Basketball players usually score points during the game using the jump shot. For this reason, the jump shot is considered to be the most important element of technique in basketball and requires a high level of performance. The aim of this study was to compare the biomechanical characteristics of the lower limbs during a jump shot without the ball and a countermovement jump without an arm swing. The differences between variables provide information about the potential that an athlete can utilise during a game when performing a jump shot. The study was conducted among 20 second-league basketball players by means of a Kistler force plate and the BTS SMART system for motion analysis. The variables measured included the take-off time, mean power, peak power, relative mean power, jump height, maximum landing force and calculated impact ratio. Surprisingly, more advantageous variables were found for the jump shot. This finding suggests a very high performance level in the jump shot in the studied group and a maximum utilisation of their motor abilities. Both types of jumps were characterised by high mean and peak power values and average heights. The high forces at landing, which result in considerable impact ratios, may have prompted the studied group to land softly. Use of the countermovement jump without an arm swing is recommended to assess and predict the progression of player’s jumping ability

    We asked how team dynamics can be captured in relation to function by considering games in the first round of the NBA 2010 play-offs as networks. Defining players as nodes and ball movements as links, we analyzed the network properties of degree centrality, clustering, entropy and flow centrality across teams and positions, to characterize the game from a network perspective and to determine whether we can assess differences in team offensive strategy by their network properties. The compiled network structure across teams reflected a fundamental attribute of basketball strategy. They primarily showed a centralized ball distribution pattern with the point guard in a leadership role. However, individual play-off teams showed variation in their relative involvement of other players/positions in ball distribution, reflected quantitatively by differences in clustering and degree centrality. We also characterized two potential alternate offensive strategies by associated variation in network structure: (1) whether teams consistently moved the ball towards their shooting specialists, measured as “uphill/downhill” flux, and (2) whether they distributed the ball in a way that reduced predictability, measured as team entropy. These network metrics quantified different aspects of team strategy, with no single metric wholly predictive of success. However, in the context of the 2010 play-offs, the values of clustering (connectedness across players) and network entropy (unpredictability of ball movement) had the most consistent association with team advancement. Our analyses demonstrate the utility of network approaches in quantifying team strategy and show that testable hypotheses can be evaluated using this approach. These analyses also highlight the richness of basketball networks as a dataset for exploring the relationships between network structure and dynamics with team organization and effectiveness.

    Full Text Available Background: Athletes focus their training on two major goals, i.e., avoidance of the injury and increasing the performance. Balance training has been widely used in competitive sports to improve the balance and thus reduce the risk of injury, for example, ligamentous sprains, which are very common in Basketball. On the other hand, various drills are being used to improve the performance parameters such as agility. Our effort is to find out an exercise program which focuses on balance training and see whether it has any effect on agility. Methods: The study design was a Pretest-Posttest Control-Group Design. 30 healthy school level Male Basketball Players were selected from V-One Basketball Academy, Don Bosco Basketball Academy, Modern School Basketball Academy, New Delhi. They were randomly divided into two groups. Group A performed dynamic balance training 3 sessions per week for 4 weeks. Group B performed conventional exercises throughout the duration of the study. Outcome measure, i.e., T- test was measured pre and post 4 week period. Results: Data analysis was done by Independent t test and Paired t test for between group analysis and within group analysis respectively. There was a significant reduction in T-test times in the experimental group as compared to the control group (‘p’ value <0.05 while there was no significant improvement in the control group. Conclusion: Four weeks of dynamic balance training significantly improved agility as detected by T-test. Thus it can be concluded that the used protocol can be incorporated in the training regimes to reduce the risk of injury as well as improve the performance.

    Full Text Available The aim of this study was to identify the relative age effect (RAE in young Polish male (n = 3849 and female (n = 3419 basketball players aged 14 to 22 years competing in the elite games of the Polish Youth Championships. The distribution of birth dates, body height, players’ match statistics, and the results of teams participating in championships were identified. The RAE was observed in male and female group, regardless of players age. Nevertheless, the greatest disproportion in the distribution of dates of birth was found in U16 group of boys (V = 0.25, p < 0.0001. Significant differences in body height were identified in U14 and U16 groups of boys (p < 0.0001 and U14 group of girls (p < 0.01. The RAE was the most detrimental in the group of boys from teams ranked 9th or lower (p < 0.0001. The groups of male and female basketball players from the top 3 teams had the highest average body height (p < 0.001. In U14 boys, significantly higher match results and performance index ratings (PIR were observed for players born in the first half of a calendar year. The research results show the impact of the RAE on the success of youth basketball teams in Poland. The month of birth, body height and sex may determine sporting achievements in youth basketball. Coaches should consider the chronological age and pubertal growth acceleration (APHV-age at peak height velocity of players to optimize the process of identifying gifted basketball players, especially among boys of 14 years of age.

    Using research methodology for analysis of secondary data, statistical data for five National Basketball Association (NBA) seasons (1993-1994 to 1997-1998) were examined to test for a relationship between team assists (a behavioral measure of teamwork) and win-loss record. Rank-difference correlation indicated a significant relationship between the two variables, the coefficients ranging from .42 to .71. Team assist totals produced higher correlations with win-loss record than assist totals for the five players receiving the most playing time ("the starters"). A comparison of "assisted team points" and "unassisted team points" in relationship to win-loss record favored the former and strongly suggested that how a basketball team scores points is more important than the number of points it scores. These findings provide circumstantial support for the popular dictum in competitive team sports that "Teamwork Means Success-Work Together, Win Together."

    This literature review evaluates the significance of dental injuries and their relationship to specific sports activities. Many studies have been published on individual sports or groups of sports but most pertain to specific age groups or levels of competition. Research suggests that many sports that do not require mouthguards should encourage male and female participants to use orofacial protectors. Athletes, coaches, athletic directors, athletic trainers, parents, and members of the dental community should be aware of how individuals who participate in sporting activities are at risk for dental trauma. Any sport where the potential for dental trauma can exist (such as basketball, soccer, or wrestling) should consider utilizing mouthguards to protect the competitors. The establishment of mouthguard programs for athletes of all ages, genders, and sports may help to reduce the incidence of dental trauma. A sports-related, orofacial/dental trauma reporting system is considered.

    Knee injuries account for a substantial percentage of all athletic injuries. The relative rates of knee injury for a variety of sports by sex and age need to be understood so we can better allocate resources, such as athletic trainers, to properly assess and treat injuries and reduce injury risk. To describe the epidemiology of patients with sport-related knee strain and sprain presenting to US emergency departments from 2002 to 2011. Cross-sectional study. Using the Consumer Products Safety Commission's National Electronic Injury Surveillance System and the US Census Bureau, we extracted raw data to estimate national rates of patients with knee strain and sprain presenting to emergency departments. Participants were individuals sustaining a knee strain or sprain at sports or recreation venues and presenting to local emergency departments for treatment. We included 12 popular sports for males and 11 for females. Ages were categorized in six 5-year increments for ages 5 to 34 years and one 10-year increment for ages 35 to 44 years. Incidence rates were calculated using weights provided by the National Electronic Injury Surveillance System and reported with their 95% confidence intervals for sport, sex, and age. Strain and sprain injury rates varied greatly by sport, sex, and age group. The highest injury rates occurred in football and basketball for males and in soccer and basketball for females. The most at-risk population was 15 to 19 years for both sexes. Athletes experience different rates of knee strain and sprain according to sport, sex, and age. Increased employment of athletic trainers to care for the highest-risk populations, aged 10 to 19 years, is recommended to reduce emergency department use and implement injury-prevention practices.

    Tendon mechanical properties are linked to sports performance and tendon-related injuries, such as tendinopathy. Whether habitual loading, such as participation in regular jumping activities, would induce adaptation on tendon mechanical properties remains unclear. Forty healthy subjects (10 sedentary, 15 volleyball players, and 15 basketball players) aged between 18 and 35 years were recruited. Supersonic shearwave imaging was used to measure the shear elastic modulus and thickness and cross-sectional area (CSA) of the proximal patellar tendons of both knees at 30° of flexion. Significant group differences in tendon shear elastic modulus were found among the three groups. In the dominant leg, reduction in tendon shear elastic modulus by 18.9 % (p = 0.018) and 48.7 % (p = 0.000) were observed in the basketball and volleyball players, respectively, when compared with sedentary subjects. In the non-dominant leg, reduction in tendon shear elastic modulus were 27.3 % (p = 0.034) and 47.1 % (p = 0.02) in the basketball and volleyball players, respectively. The athlete groups were found to have larger CSA but with similar tendon thickness than sedentary group. The CSA were larger by 24-29 % and by 22-24 % in the basketball players and volleyball players, for the dominant and non-dominant legs, respectively (all p < 0.05). Age and body mass are related to tendon stiffness and CSA, particularly in the sedentary subjects. The proximal patellar tendon can undergo substantial adaptation on tendon mechanical and morphological properties when exposed in jumping sports. Intrinsic factors such as age and body mass could influence tendon properties.

    Full Text Available ABSTRACT Introduction: Basketball is characterized as an intermittent sport in which currently stand out the highest intensity in which the actions occur, demanding for sport performance the optimum and homogeneous development of physical, technical, tactical, psychological and intellectual components. In this sense, the understanding of the game according to the technical and tactical actions performed and the knowledge of body’s responses are important for planning, monitoring and control of the training. Objective: The aim of this study was to describe the intensity of basketball tactical actions and the relationships between technical actions and intensity during the different game periods (GP. Methods: Ten athletes of the Brazilian male basketball elite participated in this study (27.60±5.54 years, 192.62±7.63 cm, 91.60±11.51 kg, 10.66±4.11% of body fat in six official matches of the National Basketball League (LNB, Brazil. Anthropometric measures and motor tests were performed and tactical (defensive, offensive and transition, technical [shares number (SN and efficiency ratio (ER] and physical actions [percentage of lactate threshold heart rate (%HRthr] were correlated. Spearman’s correlation coefficient was used between SN, ER and %HRthr. Results: The main results point to: (1 positive and significant relationship (except the 4th GP between SN, ER and %HRthr; (2 tactical actions presented HR near the lactate threshold, being apparently the highest median for the transitions (107.4%HRthr. Conclusion: The game is intense, with moments of HRpeak, but the median is slightly above of HRthr, that it is where the best relationship between SN and ER occurs.

J Strength Cond Res 31(4): 956-962, 2017-The aim of this investigation was to analyze the physical and physiological demands of experienced basketball players during a real and competitive game. Twenty-five well-trained basketball players (8 guards, 8 forwards, and 9 centers) played a competitive game on an outdoor court. Instantaneous running speeds, the number of body impacts above 5 g, and the number of accelerations and decelerations were assessed by means of a 15-Hz global Positioning System accelerometer unit. Individual heart rate was also recorded using heart rate monitors. As a group mean, the basketball players covered 82.6 ± 7.8 m·min during the game with a mean heart rate of 89.8 ± 4.4% of maximal heart rate. Players covered 3 ± 3% of the total distance running at above 18 km·h and performed 0.17 ± 0.13 sprints per minute. The number of body impacts was 8.2 ± 1.8 per minute of play. The running pace of forwards was higher than that of centers (86.8 ± 6.2 vs. 76.6 ± 6.0 m·min; p ≤ 0.05). The maximal speed obtained during the game was significantly higher for guards than that for centers (24.0 ± 1.6 km·h vs. 21.3 ± 1.6 km·h; p ≤ 0.05). Centers performed a lower number of accelerations/decelerations than guards and forwards (p ≤ 0.05). In conclusion, the extraordinary rates of specific movements performed by these experienced basketball players indicate the high physiological demands necessary to be able to compete in this sport. The centers were the basketball players who showed lower physiological demands during a game, whereas there were no differences between guards and forwards. These results can be used by coaches to adapt basketball training programs to the specific demands of each playing position.

    Context: A major challenge in the field of sports injury epidemiology is identifying the appropriate denominators for injury rates. Objective: To characterize risk of injury from participation in basketball, football, and soccer in the United States, using hours of participation as the measure of exposure, and to compare these rates with those derived using population estimates in the denominator. Design: Descriptive epidemiology study. Setting: United States, 2003–2007. Participants: People ages 15 years and older who experienced an emergency department–treated injury while playing basketball, football, or soccer. Main Outcome Measure(s): Rates of emergency department–treated injuries resulting from participation in basketball, football, or soccer. Injury rates were calculated for people ages 15 and older for the years 2003–2007 using the U.S. population and hours of participation as the denominators. The risk of injury associated with each of these sports was compared for all participants and by sex. Results: From 2003 through 2007, annual injury rates per 1000 U.S. population were as follows: 1.49 (95% confidence interval [CI] = 1.30, 1.67) in basketball, 0.93 (95% CI = 0.82, 1.04) in football, and 0.43 (95% CI = 0.33, 0.53) in soccer. When the denominator was hours of participation, the injury rate in football (5.08 [95% CI = 4.46, 5.69]/10 000 hours) was almost twice as high as that for basketball (2.69 [95% CI = 2.35, 3.02]/10 000 hours) and soccer (2.69 [95% CI = 2.07, 3.30]/10 000 hours). Conclusions: Depending on the choice of denominator, interpretation of the risk of an emergency department–treated injury in basketball, football, or soccer varies greatly. Using the U.S. population as the denominator produced rates that were highest in basketball and lowest in soccer. However, using hours of participation as a more accurate measure of exposure demonstrated that football had a higher rate of injury than basketball or soccer for both males and

    The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement’s themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities. This document summarises the approaches discussed by medical representatives from the governing bodies of 10 different contact and collision sports in Dublin, Ireland in July 2017. Those sports are: American football, Australian football, basketball, cricket, equestrian sports, football/soccer, ice hockey, rugby league, rugby union and skiing.

    Full Text Available This study presents the differences of competition between mini-basketball with the traditional rules (5-a-side and minibasket with rule modifications (3-a-side such as: reduced number of players on court, compulsory participation in 2 of the match's 4 periods, reduced court size, placing the free throw line at 3m from the basket, and including a three-point line. The sample that was selected included 47 mini-basketball players, and the study was carried out using a quasi-experimental design without a control group. The aim was to determine the effect of rule modifications on the participation of the player with the ball. It was demonstrated that the degree of individual participation is greater in mini-basketball with modified rules.

    2018-01-01

    Concussions are common incidences in sports. However, game-specific characteristics such as tactics, field positions, etc. might positively/negatively contribute to the occurrence of mild traumatic brain injuries (mTBI) in various sports such as soccer, volleyball, handball, or basketball. Thus, the intention of this study was to analyze game-specific characteristics of concussive incidents in active players from the perspective of different sportive disciplines. Four sport-specific questionnaires for soccer, handball, volleyball and basketball were established using an online survey tool. A total of 3001 participants completed the questionnaires. 18% of the participants answered that they had experienced a concussion which significantly differed depending on the sport practiced (χ2(3)=56.868, Pconcussions on the amateur level, volleyball players experienced most on the professional level and basketball players during leisure play (χ2(9)=112.667, Pconcussions by a collision with another player, volleyball players instead experienced most concussions by hits from the ball (χ2(6)=211.260, Pconcussive incidences (χ2(7)=19.638, Pconcussions (χ2(6)=13.617, Pconcussions are sport-specific and particularly concern amateurs. This indicates that most concussions in ball games appear in situations, where medical care units are not necessarily present. Preventive measures should therefore especially address amateurs in ball sports.

    To examine whether the psychological benefits of sports activity differ between tetraplegics and paraplegics with spinal cord injury, and investigate the effect of frequency and modes of sports activity on the psychological benefits. The Self-rating Depression Scale (SDS), State-Trait Anxiety Inventory (STAI) and Profiles of Mood States (POMS) were administered to 169 male individuals with spinal cord injury (mean age=42.7 years) including 53 tetraplegics and 116 paraplegics. The subjects were divided into four groups according to their frequencies of sports activity; High-active (more than three times a week; n=32), Middle-active (once or twice a week, n=41), Low-active (once to three times a month, n=32), and Inactive (no sports participation, n=64). Analysis of variance revealed significant differences in depression for SDS, trait anxiety for STAI and depression and vigor for POMS among the groups. High-active group showed the lowest scores of depression and trait anxiety and the highest score of vigor among the four groups. In contrast, no significant difference was found for any psychological measurements between tetraplegics and paraplegics. In addition, there was no significant difference for any psychological measurements among modes (wheelchair basketball, wheelchair racing, wheelchair tennis and minor modes). These findings demonstrated that sports activity can improve the psychological status, irrespective of tetraplegics and paraplegics, and that the psychological benefits are emphasized by sports activity at high frequency.

    Full Text Available Introduction: Decades of research support the theory that when there are sports competitions the question of what to eat and drink in order to enhance sport performance. Nutrition is one of the most important factors in achieving top performance athletes. According to most studies conducted in the world's top athletes receive information from their coaches when it comes to sports nutrition, especially of the coaches involved in fitness training. (Burns, Schiller, Merrick & Wolf, 2004.The aim of this study was to determine the knowledge of sports nutrition in sports coaching. Mthods: The sample was composed of 30 licensed coaches from Montenegro (football, handball, basketball, volleyball, athletics and tennis. Knowledge of sports nutrition was tested by means of a standardized questionnaire. The questionnaire was designed to determine the knowledge manager on sports nutrition, the ingredients that are necessary in order to provide a sufficient amount of energy to training and competition, the dietary supplements, meal prior to the competition as well as dehydration and rehydration during training and competition. The survey was anonymous. The data were analyzed by statistical methods, using the statistical software STATISTICA for WINDOWS. Results: According to the results as a whole, it can be concluded that the trainer's knowledge of sports nutrition at a satisfactory level. Out of 600 responses was achieved 469 correct answers, or 78.1%. However, when looking at individual responses then satisfaction with the relative high percentage loss since the observed large gaps on very important issues related to sports nutrition. Discussion: By analyzing and comparing research results (Matkovic, Prince & Cigrovski, 2006 that in a sample of 56 coaches basketball and skiing, received 77.8% of correct answers and insight into the results of our study, it is clear that the results of the approximate value of both work, which is an indicator of quality

    Using hand-collected data from DraftKings.com, a major daily fantasy sports website, we analyze draft selections of thousands of participants in daily fantasy basketball (DFB). In our study, the first thorough examination of DFB, we show that DFB is a game in which skill is necessary for success. Using econometric analysis, we find that winning participants utilize different strategies than losing participants; for example, winning participants more frequently select NBA rookies and international players. We also find that participants paying to enter more lineups in a given contest earn profits far more often than those entering few lineups, indicating that the number of lineups entered can serve as a proxy for skill. Additionally, we provide a thorough discussion of industry characteristics, prior literature, and gameplay, which should help readers familiarize themselves with this burgeoning fantasy sports variant. This study should further the literature on the contentious activity, which has been outlawed in many U.S. states and continues to elicit controversy.

    The complexity of wheelchair sports provides the scientist with a unique challenge. There are two major components that contribute towards 'wheeled sports' performance: the athlete and the chair. It is the interaction of these two components that enable wheelchair propulsion and the sporting movements required within a given sport. This article will describe three discrete case studies on how sport scientists have worked with Great Britain coaches and practitioners to help optimise training leading to a major competition through evidence base practise. A fourth area will describe on-going work designed to address the optimisation of wheelchair configurations for wheelchair court sports. It will focus on four sports: wheelchair racing, wheelchair tennis, wheelchair basketball and wheelchair rugby. The first topic will discuss the concept of pushing economy and mechanical efficiency of wheelchair propulsion. The second topic will show how technology assists the coaching process. The third topic will illustrate the concept of sports classification, and show how training volume 'in terms of basketball shooting' may need to be individually assigned and finally future research within wheelchair team sports and chair configurations will be examined.

    Little is known about how team sport athletes individually and collectively experience sources of stress during competitive sport encounters. This study aimed to examine the nature of the stressors team sport athletes appraised during games at individual and team levels, as well as their degree of synchronization during an unfolding game. Through individual self-confrontation interviews, the activities of nine basketball players of the same team were examined in detail. The results revealed that 12 categories of stressors were reported, and categorized into two larger units reflecting stressors perceived as affecting (a) "the team functioning as a whole" and (b) "a player's own functioning". Thus, the nature and degree of similarity of the game-specific stressors experienced by basketball players within a single team were identified during a game. In addition, the findings showed six different patterns of synchronizations of team members' stressors, as well as their changes over the course of the game. They provided support for the synchronized appraisal and experience of stressors within a team during a game. By adopting an interpersonal perspective and examining the temporal interplay in team members' activities, this study shed light on stress within teams. © 2016 John Wiley & Sons A/S.

    Context: There is increased growth in sports participation across the globe. Sports specialization patterns, which include year-round training, participation on multiple teams of the same sport, and focused participation in a single sport at a young age, are at high levels. The need for this type of early specialized training in young athletes is currently under debate. Evidence Acquisition: Nonsystematic review. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Sports specialization is defined as year-round training (greater than 8 months per year), choosing a single main sport, and/or quitting all other sports to focus on 1 sport. Specialized training in young athletes has risks of injury and burnout, while the degree of specialization is positively correlated with increased serious overuse injury risk. Risk factors for injury in young athletes who specialize in a single sport include year-round single-sport training, participation in more competition, decreased age-appropriate play, and involvement in individual sports that require the early development of technical skills. Adults involved in instruction of youth sports may also put young athletes at risk for injury by encouraging increased intensity in organized practices and competition rather than self-directed unstructured free play.

    Physicians counseling athletes on the prognosis of sport-specific performance outcomes after anterior cruciate ligament reconstruction (ACLR) depend on the published literature. However, critical appraisal of the validity and biases in these studies is required to understand how ACLR affects an athlete's ability to return to sport, the athlete's sport-specific performance, and his or her ability to achieve preinjury levels of performance. This review identifies the published prognostic studies evaluating sport-specific performance outcomes after ACLR. A risk of bias assessment and summaries of return to sport and career longevity results are provided for each included study. Systematic review. Electronic databases (Ovid MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and PUBMED) were searched via a defined search strategy with no limits, to identify relevant studies for inclusion in the review. A priori defined eligibility criteria included studies measuring sport-specific performance within an athlete's sport, before and after primary ACLR. Reference lists of eligible studies were hand-searched for additional relevant studies. Data extraction was performed by use of a standardized spreadsheet. Each included study was assessed by use of 6 bias domains of the Quality in Prognosis Studies tool to critically appraise study participation, study attrition, prognostic factors, outcome measurement, confounders, and statistical analysis and reporting. Two authors independently performed each stage of the review and reached consensus through discussion. Fifteen pertinent prognostic studies evaluated sport-specific performance outcomes and/or return to play after ACLR for athletes participating in competitive soccer, football, ice hockey, basketball, Alpine ski, X-Games ski and snowboarding, and baseball. Twelve of these studies were considered to have a high level of bias. This review demonstrated that most high

    This study evaluated and compared the effectiveness of two different off-season, short-term basketball training programs on physical and technical abilities of young basketball players. Twenty-seven adolescent basketball players (14.7+/-0.5 years; Tanner stage: 3.5+/-0.5) were randomly divided into a specialized basketball training group (SP, n=10), a mixed basketball plus conditioning training group (MX, n=10) and a control group (n=7). Training included five sessions per week (100-120 min each) and was performed for 4 weeks. Maximal oxygen uptake was similarly improved after SP (4.9+/-1.8%) and MX (4.9+/-1.4%), but there was no effect on ventilatory threshold. Peak and mean power output measured during the Wingate test were also improved by a similar magnitude after SP (21+/-5%) and MX (15+/-6%). Trunk muscle endurance was equally increased (SP: 23+/-4%, MX: 25+/-5%), but arms endurance was improved significantly more after MX (50+/-11%) compared to SP (11+/-14%, pbasketball technical skills was similarly increased (by 17-27%) in both groups, with a tendency for greater improvement of the SP groups in the technical skills of shooting and passing. These results indicate that a SP basketball training program, performed exclusively on-court was as effective as a MX training program in terms of aerobic and anaerobic fitness improvement. Furthermore, the decrease of the total on-court training time in the MX group resulted in a tendency for a smaller improvement of basketball technical skills. In conclusion, both SP and MX training are equally effective in order to limit and/or reverse the detraining effects that occur during the off-season in basketball.

    Full Text Available Kinesiologic elastic tape is widely used for both clinical and sport applications although its efficacy in enhancing agonistic performance is still controversial. Aim of the study was to verify in a group of healthy basketball players whether a neuromuscular taping application (NMT on ankle and knee joints could affect the kinematic and the kinetic parameters of the jump, either by enhancing or inhibiting the functional performance. Fourteen healthy male basketball players without any ongoing pathologies at upper limbs, lower limbs and trunk volunteered in the study. They randomly performed 2 sets of 5 counter movement jumps (CMJ with and without application of Kinesiologic tape. The best 3 jumps of each set were considered for the analysis. The Kinematics parameters analyzed were: knees maximal flexion and ankles maximal dorsiflexion during the push off phase, jump height and take off velocity. Vertical ground reaction force and maximal power expressed in the push off phase of the jump were also investigated. The NMT application in both knees and ankles showed no statistically significant differences in the kinematic and kinetic parameters and did not interfere with the CMJ performance. Bilateral NMT application in the group of healthy male basketball players did not change kinematics and kinetics jump parameters, thus suggesting that its routine use should have no negative effect on functional performance. Similarly, the combined application of the tape on both knees and ankles did not affect in either way jump performance.

    The main aim of this study was to examine mediating effects in the relationships between cohesion, collective efficacy and performance in professional basketball teams. A secondary aim was to examine the correlates of collective efficacy in a professional sport. A total of 154 French and foreign professional players completed French or English versions of questionnaires about cohesion and collective efficacy. Two composite measures of individual performance were used (pre- and post-performance). Individual-level analyses were performed. Regression analyses supported two mediating relationships with collective efficacy as a mediator of the pre-performance - Group integration-task relationship, and Group integration-task as a mediator of the pre-performance - collective efficacy relationship. Statistical analyses indicated that neither Group integration-task nor collective efficacy was a better mediator in the relationship between pre-performance and the other group variables. Results also revealed positive relationships between three dimensions of cohesion (i.e. Individual attractions to the group-task, Group integration-task, Group integration-social) and collective efficacy. These findings suggest that in professional basketball teams, staff members should look after athletes who perform at a lower or below their usual level because their performances might lead them into a downward cohesion - collective efficacy spiral. Staff members should also develop a high quality of group functioning, both on and off the basketball court, given its relationship with collective efficacy.

    The aim of this study was to evaluate the effectiveness of 12 weeks of balance training to improve the balance and vertical jump abilities of young basketball players. Twenty-three players from two teams in the Under Fifteen Basketball Excellence category participated in the study. Participants were divided into two training groups: balance training (BAL, n  = 11) and isotonic training (ISO, n  = 12). Both groups were tested for balance and vertical jumps at the beginning of the competitive season and at the end of 12 weeks of specific training programme. All of the tests were performed in sustained bipodalic and monopodalic (both right and left) positions. The results showed that players who participated in balance training for 12 weeks, compared to players who trained with isotonic machines, exhibited a significantly increase in balance (bipodalic 28.3 %; right 41.4 %; left 45.8 %; p  training using unstable boards was an effective training method for improving balance and the vertical jump, which is a basketball-specific action that frequently occurs in this sport.

    Kinesiologic elastic tape is widely used for both clinical and sport applications although its efficacy in enhancing agonistic performance is still controversial. Aim of the study was to verify in a group of healthy basketball players whether a neuromuscular taping application (NMT) on ankle and knee joints could affect the kinematic and the kinetic parameters of the jump, either by enhancing or inhibiting the functional performance. Fourteen healthy male basketball players without any ongoing pathologies at upper limbs, lower limbs and trunk volunteered in the study. They randomly performed 2 sets of 5 counter movement jumps (CMJ) with and without application of Kinesiologic tape. The best 3 jumps of each set were considered for the analysis. The Kinematics parameters analyzed were: knees maximal flexion and ankles maximal dorsiflexion during the push off phase, jump height and take off velocity. Vertical ground reaction force and maximal power expressed in the push off phase of the jump were also investigated. The NMT application in both knees and ankles showed no statistically significant differences in the kinematic and kinetic parameters and did not interfere with the CMJ performance. Bilateral NMT application in the group of healthy male basketball players did not change kinematics and kinetics jump parameters, thus suggesting that its routine use should have no negative effect on functional performance. Similarly, the combined application of the tape on both knees and ankles did not affect in either way jump performance.

    Adventure and extreme sports often involve unpredictable and inhospitable environments, high velocities, and stunts. These activities vary widely and include sports like BASE jumping, snowboarding, kayaking, and surfing. Increasing interest and participation in adventure and extreme sports warrants understanding by clinicians to facilitate prevention, identification, and treatment of injuries unique to each sport. This article covers alpine skiing and snowboarding, skateboarding, surfing, bungee jumping, BASE jumping, and whitewater sports with emphasis on epidemiology, demographics, general injury mechanisms, specific injuries, chronic injuries, fatality data, and prevention. Overall, most injuries are related to overuse, trauma, and environmental or microbial exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Context: Ankle sprains are a common basketball injury. Therefore, examination of risk factors for injury in female professional basketball players is worthwhile. Objective: To examine rates of ankle sprains, associated time missed from participation, and risk factors for injury during 2 consecutive seasons. Design: Prospective cohort study. Setting: Eighteen professional basketball facilities. Patients or Other Participants: We observed 204 players from 18 female professional basketball teams for 2 consecutive seasons during a 2-year period. Main Outcome Measure(s): Using questionnaires, we recorded the incidence of ankle sprains, participation time missed, and mechanisms of injury in games and practice sessions. Potential risk factors, such as age, body mass, height, training experience, and history of ankle sprain, were examined using multivariate logistic regression. Results: Fifty of the 204 participants sustained ankle injuries; injuries included 32 ankle sprains, which translated to an ankle sprain rate of 1.12 per 1000 hours of exposure to injury. The 32 players missed 224.4 training and game sessions and an average of 7.01 sessions per injury. Most injuries occurred in the key area of the basketball court and were the result of contact. Injury rates during games were higher than injury rates during practice sessions. Centers, followed by guards and forwards, had the highest rate of injury. Players who did not wear an external ankle support had an odds ratio of 2.481 for sustaining an ankle sprain. Conclusions: Female professional basketball athletes who did not wear an external ankle support, who played in the key area, or who functioned as centers had a higher risk for ankle sprain than did other players.

    Tennis may be considered a static and dynamic form of exercise with many well-demonstrated health benefits. Tennis has similar rates of injury to other individual recreational sports and junior competitive sports, without the catastrophic risk of contact/collision sports. Classifying tennis players into junior and elite categories versus adult recreational players may help in outlining volume of play recommendations, exposure risk, and types of injuries. Junior and elite players tend to tolerate higher volumes, have more acute and lower extremity injuries, and have more serious overuse stress injuries. Adult recreational players tend to tolerate lower volumes, have more overuse and upper extremity injuries, and more conditions that are degenerative. Many tennis players also develop asymmetric musculoskeletal adaptations, which may increase risk of specific injury. Tennis-specific evaluations may identify these at-risk segments, help guide preventive strategies including technical errors, and assist in developing return-to-play recommendations. Other racket sports such as squash, badminton, and racquetball have less data available but report both acute and traumatic injuries less commonly seen in tennis.

    Few studies have evaluated the long-term effects of prophylactic ankle-brace use during a sport season. To determine the effects of prophylactic ankle-brace use during a high school basketball season on dynamic postural control and functional tests. Prospective repeated-measures design. High school athletic facility. 21 healthy high school basketball athletes (13 girls, 8 boys). The order of testing was randomized using the Star Excursion Balance Test (SEBT) for posteromedial (PM), medial (M), and anteromedial (AM) directions and 3 functional tests (FT) consisting of the single-leg crossover hop, single-leg vertical jump, and the single-leg 6-m hop for time at pre-, mid-, and postseason. After pretesting, the ankle brace was worn on both limbs during the entire 16-wk competitive basketball season. SEBT for PM, M, and AM and 3 single-leg FTs. Dynamic postural control using the SEBT and the 3 FTs improved over time, notably from pretest to posttest. The left limb was different from the right limb during the single-leg vertical jump. Effect sizes were large for pretest to posttest for the 3 SEBT directions and 2 of the 3 FTs. The 16-wk basketball prophylactic ankle-brace intervention significantly improved dynamic postural control and single-limb FTs over time.

    Whether the hypertrophy found in the hearts of athletes is physiologic or a risk factor for the progression of pathologic hypertrophy remains controversial. The diastolic and systolic functions of athletes with left ventricular (LV) hypertrophy usually are normal when measured by conventional methods. More precise assessment of global and regional myocardial function may be possible using a newly developed two-dimensional (2D) strain echocardiographic method. This study evaluated the effects that different types of sports have on the hearts of children and adolescents and compared the results of 2D strain and strain-rate echocardiographic techniques with conventional methods. Athletes from clubs for five different sports (basketball, swimming, football, wrestling, and tennis) who had practiced regularly at least 3 h per week during at least the previous 2 years were included in the study. The control group consisted of sedentary children and adolescents with no known cardiac or systemic diseases (n = 25). The athletes were grouped according to the type of exercise: dynamic (football, tennis), static (wrestling), or static and dynamic (basketball, swimming). Shortening fraction and ejection fraction values were within normal limits for the athletes in all the sports disciplines. Across all 140 athletes, LV geometry was normal in 58 athletes (41.4 %), whereas 22 athletes (15.7 %) had concentric remodeling, 20 (14.3 %) had concentric hypertrophy, and 40 (28.6 %) had eccentric hypertrophy. Global LV longitudinal strain values obtained from the average of apical four-, two-, and three-chamber global strain values were significantly lower for the basketball players than for all the other groups (p < 0.001).

    Full Text Available Introduction: The appeal to the research topic is caused by the actual problem: in the pedagogical practice of the higher school, the physical culture and health-improving activities in the majority do not contribute to the formation of independent, motivated and sustainable self-improvement activities by students with the help of physical culture. The traditional system of physical education is not characterized by efficiency. The formation of motivation for physical education is one of the most important problems of the modern university.Materials and methods: to assess the value potential of physical culture and sports, we set the task to identify: the attitude of students to physical culture and health, what is the social significance of physical culture, the systematic nature of physical culture and sports, the objective and subjective factors that contribute to increasing interest in physical culture and Sport as a value, the reasons that interfere with attending classes. To solve this problem, we developed a questionnaire and conducted anonymous questioning of students.Results: Having analyzed the data obtained as a result of the questionnaire, we came to the conclusion that students objectively assess their health, which many are not satisfied with; most students are not engaged in physical culture and sports, referring mainly to the lack of free time; students are ready to engage in physical culture in sections for the selected sport, to attend self-educational activities. Students mostly respond positively to the lessons in the discipline "Physical Culture", but a considerable number of students attend these classes only for the sake of credit.Discussion and Conclusions: physical education, based on sports-oriented principles, includes classes in sports sections by sport: volleyball, basketball, aerobics, badminton, football, table tennis, kettlebell lifting, sports dancing, swimming, athletics, gymnastics, and for general physical

    Relationships among chronological age (CA), maturation, training experience, and body dimensions with peak oxygen uptake (VO2max) were considered in male basketball players 14-16 y of age. Data for all players included maturity status estimated as percentage of predicted adult height attained at the time of the study (Khamis-Roche protocol), years of training, body dimensions, and VO2max (incremental maximal test on a treadmill). Proportional allometric models derived from stepwise regressions were used to incorporate either CA or maturity status and to incorporate years of formal training in basketball. Estimates for size exponents (95% CI) from the separate allometric models for VO2max were height 2.16 (1.23-3.09), body mass 0.65 (0.37-0.93), and fat-free mass 0.73 (0.46-1.02). Body dimensions explained 39% to 44% of variance. The independent variables in the proportional allometric models explained 47% to 60% of variance in VO2max. Estimated maturity status (11-16% of explained variance) and training experience (7-11% of explained variance) were significant predictors with either body mass or estimated fat-free mass (P ≤ .01) but not with height. Biological maturity status and training experience in basketball had a significant contribution to VO2max via body mass and fat-free fat mass and also had an independent positive relation with aerobic performance. The results highlight the importance of considering variation associated with biological maturation in aerobic performance of late-adolescent boys.

    Literature suggests that dietary intake of elite athletes may differ between training and competition days. In addition, despite the importance of nutrition in sports and the popularity of basketball, studies on the diet of basketball players are scarce. Therefore, the aim of the present study was to assess dietary intake and diet quality in training and competition days in a team of elite basketball players receiving daily professional nutritional counseling. One elite basketball team (N.=15) participating in EuroLeague volunteered for the study. The team employed a certified dietitian, responsible for providing individualized nutritional evaluation and counseling, dietary planning and supervision of the diet of all the players. Dietary intake was assessed using 24-hour recalls and the Healthy Eating Index (HEI) was then calculated. All players exhibited adequate (i.e., >80) HEI score (raw and adjusted for energy intake [EI]), on both training and competition days. Although daily energy, carbohydrate and protein intakes were greater during training compared to competition days (26.0 [21.7, 26.4] vs. 19.5 [19.3, 22.1] MJ, 7.6±1.5 vs. 6.8±0.9 g/kg of body weight [BW] and 2.6±0.6 vs. 2.2±0.2 g/kg BW, respectively; all Pvs. 94.0 [94.0, 94.0] and 89.7 [88.4, 89.7] vs. 92.7 [91.7, 92.8], respectively; all P≤0.001) due to lower total grains, whole grains and total vegetables consumption and greater saturated fats consumption (Psports dietitians exhibit adequate diet quality, with the highest possible observed during competition days.

    In preparation for the Olympics, there is a limited opportunity for coaches and athletes to interact regularly with team performance indicators providing important guidance to coaches for enhanced match success at the elite level. This study examined the relationship between match outcome and team performance indicators during men’s basketball tournaments at the Olympic Games. Twelve team performance indicators were collated from all men’s teams and matches during the basketball tournament of the 2004-2016 Olympic Games (n = 156). Linear and non-linear analyses examined the relationship between match outcome and team performance indicator characteristics; namely, binary logistic regression and a conditional interference (CI) classification tree. The most parsimonious logistic regression model retained ‘assists’, ‘defensive rebounds’, ‘field-goal percentage’, ‘fouls’, ‘fouls against’, ‘steals’ and ‘turnovers’ (delta AIC winning (93.2%). Match outcome during the men’s basketball tournaments at the Olympic Games was identified by a unique combination of performance indicators. Despite the average model accuracy being marginally higher for the logistic regression analysis, the CI classification tree offered a greater practical utility for coaches through its resolution of non-linear phenomena to guide team success. Key points A unique combination of team performance indicators explained 93.2% of winning observations in men’s basketball at the Olympics. Monitoring of these team performance indicators may provide coaches with the capability to devise multiple game plans or strategies to enhance their likelihood of winning. Incorporation of machine learning techniques with team performance indicators may provide a valuable and strategic approach to explain patterns within multivariate datasets in sport science.

    On-field management and return-to-play guidelines aim to ensure the identification and appropriate management of the concussed athlete. Compliance with current guidelines in many settings is unknown. We assessed whether key components of current concussion guidelines are being followed in child athletes. Prospective observational study. Data were collected from children (5-18 years) presenting to a paediatric emergency department with sport-related concussion via researcher-administered surveys in the emergency department and during a follow up phone call. On hospital discharge all patients received a return to sports fact sheet based on the International Concussion in Sports Group. Ninety-three had sustained a concussion (mean age 12.7 (±0.27) years, 83% male). Sports played included Australian Football (47%), soccer (12%), rugby (9%) basketball (8%), other (25%). 82% participated in organised sports. Concussive signs or symptoms included loss of consciousness (41%), disorientation (36%), vomiting (23%), amnesia (30%), headache (60%). For concussive injury in organised sports (n=76), overall 42% were not managed according to recommended guidelines: 19% were not immediately removed from play, 29% were allowed to return to play on the same day and 27% were not assessed by qualified personnel. 93% of parents and 96% of patients were unaware of concussion or return-to-play guidelines from their organisations. Overall, 72% were compliant with provided return-to-play guidelines. Many children with sports related-concussion are not formally assessed on-field and continue to play. On-field concussion management and return to play practices are often suboptimal. Awareness and education of coaches, teachers, parents and children need to be improved.

Nowadays way of life causes reduced movement in whole population, such as in preeschool children. Reducing movement in preeschool children can result many postural disturbances and body deformities. In that case it was made systematic medical chackup in children 5-6 years old from ’’Cvrčak’’- Niš kindergarden on food deformities during last seven years (2004-2010. Received results showed desastrous level on food arch, reduced function of food muscules. The idea was that reason for that was childs` reduced body activities, from 2008. year it was made and start to realize the project „komunication and culture in sport“, in regard to grow up sport culture level in children, parents and teachers. As all of us is born having some predispozitions, it was given chance to sport clubs to present to children, teachers and parents all of sport-recreative bases. In cooperation with physical education expert service Office and coatches from sport clubs in Niš, it was made the sport-recreative Project. In one cyclus during one year children are included in next sports: rhythmic gymnastics, judo, tennis, basketball, vollyball, foodball, athledics, skating, skiing. The project gave wonderfull results: a great number of children joined sport clubs, more sport-recreative activities in children, growing right mind about body exercises needs, such as better statistic results after childrens` systematic medical chackup in 2009. and 2010. year.

    Dancers have a lower incidence of anterior cruciate ligament (ACL) injury compared to athletes in sports that involve cutting and landing motions. Balance can impact ACL injury risk and is related to neuromuscular control during movement. The purpose of this study was to investigate whether balance differences exist among female dancers and female soccer and basketball athletes. Fifty-eight female dancers, soccer, and basketball athletes (16.5 ± 1.6 yrs, 1.6 ± 0.2 m, 60.2 ± 14.1 kg) completed the Stability Evaluation Test (SET) on the NeuroCom VSR Sport (NeuroCom International, Clackamas, OR) to measure sway velocity. Video records of the SET test were used for Balance Error Scoring System (BESS) test scoring. A oneway ANCOVA compared composite sway velocity and BESS scores among sports. There was no statistically significant difference for sway velocity or BESS among sports (sway velocity soccer 2.3 ± 0.4, dance 2.2 ± 0.4, and basketball 2.4 ± 0.4; BESS soccer 13.6 ± 5.0, dance 11.9 ± 5.5, and basketball 14.9 ± 5.1, p>0.05). Balance was similar among athletes participating in different sports (dance, basketball, and soccer). Quasi-static balance may not play a significant role in neuromuscular control during movement and not be a significant risk factor to explain the disparity in ACL injury incidence among sports. Future research should examine the effects of dynamic balance and limb asymmetries among sports to elucidate on the existing differences on ACL injury incidence rates.

    Full Text Available The aim of the study was to compare selected biomechanical parameters obtained during various types of vertical jumps made by volleyball and basketball players on a dynamometric platform. The study involved 10 volleyball players and 10 basketball players in the age of 21.1 ± 1.81 years of the AZS AWF Warsaw sport club. The athletes performed two vertical jumps on a KISTLER platform. The first jump was a counter-movement jump (CMJ and the second was a spike jump (SPJ – a vertical jump which is performed with a 3-4 step run-up before the take-off. The participant's task was to take off and land on the platform. On the basis of the statistical analysis it was shown that only the type of jump had a significant effect on the height and power. The type of team sport did not affect the level of performance. In addition, it was found that the height of the jump is affected by the counter movement phase with hand swing and run-up. The volleyball and basketball players were equally able to get higher values for certain parameters in successive runs. Due to lack of statistically significant differences it was decided to combine two groups of athletes into one. For both jumps, the relationship between peak power and jump height was found at significance level p <0.001. Dynamometric platform can be used to check the athlete's height of jump and power of lower extremities. This method allows to verify the effectiveness of different types of training.

    Recent studies have found little empirical evidence to suggest that National Basketball Association (NBA) and Major League Baseball (MLB) players have hot streaks. This has led some to suggest that hot hands do not exist and that offensive and defensive strategies adjusting to perceived hot hands are suboptimal. We study the MLB's Home Run Derby and the NBA's 3-point Shootout. When there is no defense, extended time between shots has been removed, and shot or swing selection is constant, we find evidence that player performance is nonstationary. Our results are consistent with beliefs long held by players, coaches, and fans, research on the importance of self-efficacy in sports, and studies that support the existence of hot streaks in sports with no or limited defense. © 2013 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    2011-10-01

    The inclusion of able-bodied athletes within disability sport, a phenomenon known as reverse integration, has sparked significant debate within adapted physical activity. Although researchers and practitioners have taken up positions for or against reverse integration, there is a lack of supporting research on the experiences of athletes who already play in such settings. In this study, we explore how competitive female athletes who have a disability experience reverse integration in Canadian wheelchair basketball. Athletic identity was used as the initial conceptual framework to guide semistructured interviews with nine participants. The results suggest that participation in this context contributed to positive athletic identities. Interviews also pointed to the unexpected theme of "what's the difference?" that this sporting context provided a space for the questioning and creative negotiation of the categories of disability and able-bodiedness. Methodologically, this paper also explores the possibilities and challenges of inter- worldview and insider-outsider research collaboration.

    Full Text Available The quiet eye is a perceptual skill associated with expertise and superior performance; however, little is known about the transfer of quiet eye across domains. We attempted to replicate previous skill-based differences in quiet eye and investigated whether transfer of motor and perceptual skills occurs between similar tasks. Throwing accuracy and quiet eye duration for skilled and less-skilled basketball players were examined in basketball free throw shooting and the transfer task of dart throwing. Skilled basketball players showed significantly higher throwing accuracy and longer quiet eye duration in the basketball free throw task compared to their less-skilled counterparts. Further, skilled basketball players showed positive transfer from basketball to dart throwing in accuracy but not in quiet eye duration. Our results raise interesting questions regarding the measurement of transfer between skills.

  1. Motor experience with a sport-specific implement affects motor imagery

    Zhu, Hua; Shen, Cheng; Zhang, Jian

    2018-01-01

    The present study tested whether sport-specific implements facilitate motor imagery, whereas nonspecific implements disrupt motor imagery. We asked a group of basketball players (experts) and a group of healthy controls (novices) to physically perform (motor execution) and mentally simulate (motor imagery) basketball throws. Subjects produced motor imagery when they were holding a basketball, a volleyball, or nothing. Motor imagery performance was measured by temporal congruence, which is the correspondence between imagery and execution times estimated as (imagery time minus execution time) divided by (imagery time plus execution time), as well as the vividness of motor imagery. Results showed that experts produced greater temporal congruence and vividness of kinesthetic imagery while holding a basketball compared to when they were holding nothing, suggesting a facilitation effect from sport-specific implements. In contrast, experts produced lower temporal congruence and vividness of kinesthetic imagery while holding a volleyball compared to when they were holding nothing, suggesting the interference effect of nonspecific implements. Furthermore, we found a negative correlation between temporal congruence and the vividness of kinesthetic imagery in experts while holding a basketball. On the contrary, the implement manipulation did not modulate the temporal congruence of novices. Our findings suggest that motor representation in experts is built on motor experience associated with specific-implement use and thus was subjected to modulation of the implement held. We conclude that sport-specific implements facilitate motor imagery, whereas nonspecific implements could disrupt motor representation in experts. PMID:29719738

    Full Text Available Excellent performance in sport has a strong positive relationship with the accumulated hours of practice. The specialization years are seen as a decisive moment to lift the skill level, athletic readiness and commitment but the selection and orientation of talent has been strongly dependent of biological and motor variables. The purpose of this study is to describe the achievement and motivation variables that can explain the belonging to an elite competitive level of young basketball players. Eighty-two basketball players under 16 years fulfilled the WOFO Questionnaire (Spence and Helmreich, 1983, and an adapted version of the DPMQ (De Bruin, Rikers and Schmidt, 2007. Forty players (mean age 15. 8 ± 0.96 were engaged in high performance centres and forty-two (mean age 15.6 ± 1.01 played in national level clubs. A decision tree and a random forest analysis between elite and national level players were performed. The most discriminant variable was Will to Excel, with 85,2% true positives in elite or national level. Mastery and competitiveness did not enter the final model. The will to reach excellence in performance can be considered as a condition to engage in more specialized and demanding practice. The assessment of the path to expertise only through motor variables or through the accumulated hours of deliberate practice is limited and can lead to mistaken identification or orientation of young sport talents. The use of a more comprehensive model is needed

    The purpose of this study was to evaluate the effects of a complex training program, a combined practice of weight training and plyometrics, on explosive strength development of young basketball players. Twenty-five young male athletes, aged 14-15 years old, were assessed using squat jump (SJ), countermovement jump (CMJ), Abalakov test (ABA), depth jump (DJ), mechanical power (MP), and medicine ball throw (MBT), before and after a 10-week in-season training program. Both the control group (CG; n = 10) and the experimental group (EG; n = 15) kept up their regular sports practice; additionally, the EG performed 2 sessions per week of a complex training program. The EG significantly improved in the SJ, CMJ, ABA, and MBT values (p training to improve the upper and lower body explosivity levels in young basketball players. In conclusion, this study showed that more strength conditioning is needed during the sport practice season. Furthermore, we also conclude that complex training is a useful working tool for coaches, innovative in this strength-training domain, equally contributing to a better time-efficient training.

    Full Text Available Dominé par les joueurs africains-américains, le basket-ball est aujourd’hui considéré comme un sport noir. Tout au long du xxe siècle, la communauté noire américaine a particulièrement investi ce sport jusqu’à ce que les joueurs africains-américains représentent l’immense majorité des effectifs de la National Basketball Association, la ligue professionnelle américaine. Depuis plus d’un siècle, les causes de cette domination sportive donnent lieu à des controverses virulentes recourant en général à des arguments génétiques (les noirs sont athlétiquement supérieurs ou environnementaux (la pauvreté urbaine pousse les noirs vers le sport. Néanmoins, on peut plutôt voir dans cette domination une volonté politique de lutter pour l’égalité, la dignité et la reconnaissance. Que la communauté noire américaine les célèbre comme une chance d’intégration ou les critique comme une dangereuse illusion, le sport et le basket-ball ont ainsi été un aspect essentiel des luttes politiques africaines-américaines.Basketball is today dominated by African-American players and is consequently considered as a black sport. Throughout the 20th century, vast numbers of African Americans became involved in this sport, to such an extent that African Americans have come to represent the great majority of NBA players. For more than a century, this athletic domination has given rise to heated controversies: most of the time it was explained using genetics (Blacks are athletically superior or environmental theories (the poverty of urban Blacks leads them toward sports. However, one can see in this domination a political will to fight for equality, dignity, and recognition. Thus, whether it is celebrated by African Americans as a chance for racial uplift or criticized as a dangerous illusion, sport and basketball have been a central aspect of their political struggles.

    Full Text Available The purpose of the study was to examine how wheelchair basketball players’ self-esteem and motivation levels impact on their state and trait anxiety levels. The Coopersmith Self-Esteem Inventory, Sport Motivation Scale and STAI (State Trait Anxiety Inventory were applied to the athletes before a competition. Data were collected from 124 athletes with disabilities. In this study, descriptive statistical techniques, Pearson product moment correlation and multiple regression analysis (enter method were used. Multiple regression analyses indicated that self-esteem, intrinsic motivation, extrinsic motivation and amotivation, all of which function as predicting variables, predicted 42% variance in state anxiety and 50% variance in trait anxiety. Motivation and self-esteem are the best predictors of trait and state anxiety among the premier league wheelchair basketball players. Finally, a review of factors that impact on anxiety and quality of performance such as motivation and self-esteem is provided.

    There is a lack of information about the influence of age on functional movement tests (FMT) and performance tests as well as in their relationships in young basketball players. The purpose of the present study was to determine the variations in FMT and jump and/or sprint performance scores between age groups (U-14 vs. U-16) in Highly-trained young basketball players. The second purpose was to investigate the relationship between FMT for lower body and jump and/or sprint performance in highly-trained young (U-14 and U-16) male basketball players. Descriptive study. Thirty elite young (U-14 to U-16) male basketball players performed several FMT (weight-bearing dorsiflexion test [WB-DF] and a modified Star Excursion Balance test [SEBT]) and performance including unilateral and bilateral countermovement jumps, unilateral horizontal jumping, linear sprinting and performance tests. All anthropometric and performance tests showed a statistically significant advantage (pjump with left leg (p=0.127). Five out of the eight FMT performed showed a statistically significant advantage (pjump and/or sprint performance test between age groups (U-16 vs U-14). The findings of this study support the idea that the age of the player should be considered when interpreting FMT scores, which could have implications when implementing the FMT for injury risk prediction. 2b.

    Patellar tendinopathy (PT) is a common overuse injury of the patellar tendon in jumping athletes. In a recent large cross-sectional study from 2008 several factors were identified that may be associated with the etiology of PT. However, because of the study design no conclusions could be drawn about causal relations. The primary aim of the current study is to investigate whether the factors identified in the previous 2008 study can also be prospectively recognized as predictors of symptomatic PT in 2011. Nine hundred twenty-six Dutch elite and non-elite basketball and volleyball players from the previous study were invited again to complete an online survey about knee complaints and risk factors for PT in 2011. The logistic regression included 385 athletes of which 51 (13%) developed PT since 2008. Male gender [odds ratio (OR) 2.0, 95% confidence interval (CI) 1.1-3.5] was found to be a risk factor for developing PT. No sports-related variables could be identified to increase the risk of developing PT, but some evidence was found for performing heavy physically demanding work, like being a nurse or a physical education teacher (OR 2.3, 95% CI 0.9-6.3). These findings indicate that, when considering preventive measures, it is important to take into account the total tendon load. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available The objectives of this study were to determine the relationship among game performance, injury rate, and practice exposure in a professional male basketball team. A retroospective analysis of prospective collected data was conducted over seven consecutive seasons (2007/2008 to 2013/2014. Data collection included sports performance during competition (statistical evaluation, injury rate, and total exposure (games and practices. Over the surveillance period, 162 injuries (91 practice; 71 matches occurred over 32,668 hours of exposure (556 games and 2005 practices. There was a strong positive correlation between: 1 exposure (total number of practices and hours of exposure and the total number of injuries (r = 0.77; p = 0.04; 2 exposure (total hours of exposure and total hours of practice exposure and performance (total team ranking (r = 0.77 and p = 0.04, and r = 0.8 and p = 0.03, respectively; and 3 total number of injuries and performance (total team ranking (r = 0.84; p = 0.02. While increasing practice and competition time is related to greater team performance, it also increases the number of injuries. However, higher injury rates were not associated with worse overall team performance. Efforts to reduce high-risk activity during practice, optimally replaced with injury prevention training, might help to reduce injury risk.

    This study investigated the effect of a periodized training program on internal training load (ITL), recovery-stress state, immune-endocrine responses, and physical performance in 19 elite female basketball players. The participants were monitored across a 12-week period before an international championship, which included 2 overloading and tapering phases. The first overloading phase (fourth to sixth week) was followed by a 1-week tapering, and the second overloading phase (eighth to 10th week) was followed by a 2-week tapering. ITL (session rating of perceived exertion method) and recovery-stress state (RESTQ-76 Sport questionnaire) were assessed weekly and bi-weekly, respectively. Pretraining and posttraining assessments included measures of salivary IgA, testosterone and cortisol concentrations, strength, jumping power, running endurance, and agility. Internal training load increased across all weeks from 2 to 11 (p ≤ 0.05). After the first tapering period (week 7), a further increase in ITL was observed during the second overloading phase (p ≤ 0.05). After the second tapering period, a decrease in ITL was detected (p ≤ 0.05). A disturbance in athlete stress-recovery state was noted during the second overloading period (p ≤ 0.05), before returning to baseline level in end of the second tapering period. The training program led to significant improvements in the physical performance parameters evaluated. The salivary measures did not change despite the fluctuations in ITL. In conclusion, a periodized training program evoked changes in ITL in elite female basketball players, which appeared to influence their recovery-stress state. The training plan was effective in preparing participants for competition, as indicated by improvements in recovery-stress state and physical performance after tapering.

    Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. Evidence Acquisition: PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. Results: For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Conclusion: Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

    Young, active candidates for total shoulder arthroplasty (TSA) are a unique group of patients. Not only do they demand longevity and improved function, but they also desire a return to physical activities. To determine the rate of return to sports in patients aged ≤55 years undergoing TSA. Case series; Level of evidence, 4. This was a retrospective review of consecutive patients who underwent anatomic TSA at a single institution. Exclusion criteria included age at the time of surgery >55 years and sports questionnaire, American Shoulder and Elbow Surgeons (ASES) score, and visual analog scale (VAS) score. From 70 eligible patients, 59 patients (61 shoulders) were included with an average follow-up of 61.0 months (range, 25-103 months) and average age at the time of surgery of 48.9 years (range, 25-55 years). The average VAS score improved from 5.6 to 0.9 ( P sports. Moreover, patients in 96.4% of shoulders (55/57) restarted at least 1 sport at an average of 6.7 months. Direct rates of return were as follows: fitness sports (97.2%), golf (93.3%), singles tennis (87.5%), swimming (77.7%), basketball (75.0%), and flag football (66.7%). Patients in 47 shoulders (82.4%) returned to a similar or higher level of sports; 90.3% returned to high-demand sports, and 83.8% returned to high upper extremity sports. There was no significant difference in rates of return to sports by body mass index, sex, age, preoperative diagnosis, revision status, and dominant extremity. In patients aged ≤55 years undergoing TSA, there was a 96.4% rate of return to ≥1 previous sports at an average of 6.7 months. Furthermore, at an average follow-up of 61.0 months, no patients needed revision of their glenoid component, despite an 83.8% rate of return to high upper extremity sports. While caution should still be advised in young, active patients undergoing TSA, these results demonstrate a high satisfaction rate and improved ability to return to most sports after surgery.

The time between successive scoring events follows an exponential distribution, with little memory between events. We account for a wide variety of statistical properties of scoring, such as the distribution of the score difference between opponents and the fraction of game time that one team is in the lead.

    Full Text Available The sport business must determine how to get its products from the manufacturer or producer to the consumer. Additionally, in this industry, there are products produced at a point where the consumer must be present at its production to consume the product. These products are sports events, such as a professional basketball game, a football match, or a super cross race. In these types of products, the event - the product - is staged at a facility where fans will gather to watch. The sport business will have made decisions regarding the facility in relation to location and other factors that will make the facility attractive to the consumer as a place in which to consume these types of products. This paper presents a brief overview about distribution in the sport business industry, the role of distribution in marketing strategy, the selection of a distribution network, and the types of distribution intermediaries available for moving and / or offering sport business industry products.

    Influence of gender and sports training on QT variables such as QT interval and dispersion (QT dispersion: QTD) in young elite athletes were evaluated. Subjects included 104 male and 97 female Japanese elite athletes (mean age 21.6 years). Sports included basketball, fencing, gymnastics, judo, swimming, tennis, track and field and volleyball. Age-matched healthy non-athletes (32 men and 20 women) were enrolled as controls. QT measurements were manually obtained from a 12-lead resting electrocardiogram and QTD was calculated as the difference between the longest and shortest QT intervals. A corrected QT interval (QTc) was obtained using Bazett's formula. Subjects were divided into two groups; an endurance training group and a static training group on the basis of their training types. Maximum and minimum QTc were significantly longer in female athletes than in male athletes (max: 414.2 vs. 404.5 ms, min: 375.1 vs. 359.2 ms, pgender and different characteristics of sports training may affect QT variables even in young elite athletes. Vigorous static exercise training may independently prolong QT variables.

    2018-03-01

    The purpose of this study was to provide an integrated analysis of a teacher's peer-teaching mediation strategies, the student-coaches' instruction, and the students' gameplay development across 3 consecutive seasons of sport education. Twenty-six 7th-grade students participated in 3 consecutive sport education seasons of invasion games (basketball, handball, and soccer). The research involved 3 action research cycles, 1 per season, and each cycle included the processes of planning, acting and monitoring, reflecting, and fact finding. Data collection consisted of videotape and audiotape records of all 47 lessons, a reflective field diary kept by the first author in the role of teacher-researcher, and a total of 24 semistructured focus-group interviews. Trustworthiness criteria for assuring the quality of qualitative research included extensive data triangulation, stakeholders' crosschecking, and collaborative interpretational analysis. Through the application of systematic preparation strategies, student-coaches were able to successfully conduct team instruction that resulted in students' tactical development and improved performance. Aspects such as the study of predominant configurations of players' gameplay and similar tactical principles across games within the same category prevented a setback in the complexity of the learning content addressed at the beginning of each season. Players also showed an increasing ability to adapt gameplay to game conditions. While sport education has the capacity to develop competent players, different levels of teacher guidance and learners' instructional responsibility are necessary when teaching tactics.

    Leader behaviors have been found to vary by competitive level (6,9,11,26). Similar differences based on the competitive environment have been reported with strength coaches and their training emphases (15,28) but not their leadership style behaviors. This latter area is important to explore because strength coach leader behaviors may result in enhanced cooperation, improved communication, and improved athlete psychological and emotional well-being (14,23,25,27). Accordingly, the purpose of this study was to examine the differences in self-perceived leadership styles of National Basketball Association, Division I-A (DI-A) men's basketball, and Division II (DII) men's basketball strength and conditioning coaches. The self-perceived leadership styles of 145 men's basketball strength coaches (National Basketball Association [NBA]=22, DI-A=92, and DII=31) were obtained using the Revised Leadership Scale for Sport (26,41). Frequency data about demographics and training methods were also collected. No significant differences were reported for positive feedback. Otherwise, NBA strength coaches reported more democratic leadership style behaviors than DI-A strength coaches. Division I-A strength coaches were found to be more autocratic than NBA or DII strength coaches. Both NBA and DI-A strength coaches indicated a higher level of training and instruction than did DII strength coaches. National Basketball Association strength coaches also reported engaging in more situational and socially supportive leader behaviors than DI-A and DII strength coaches. Leader behaviors can positively and negatively impact an athlete (23); thus, strength coaches need to evaluate their competitive environment and reflect on the impact of their behaviors and how their approach to leading athletes may need to vary based on the situation.

    The soaring amount of data, especially spatial-temporal data, recorded in recent years demands for advanced analysis methods. Neural networks derived from self-organizing maps established themselves as a useful tool to analyse static and temporal data. In this study, we applied the merge self-organising map (MSOM) to spatio-temporal data. To do so, we investigated the ability of MSOM's to analyse spatio-temporal data and compared its performance to the common dynamical controlled network (DyCoN) approach to analyse team sport position data. The position data of 10 players were recorded via the Ubisense tracking system during a basketball game. Furthermore, three different pre-selected plays were recorded for classification. Following data preparation, the different nets were trained with the data of the first half. The training success of both networks was evaluated by achieved entropy. The second half of the basketball game was presented to both nets for automatic classification. Both approaches were able to present the trained data extremely well and to detect the pre-selected plays correctly. In conclusion, MSOMs are a useful tool to analyse spatial-temporal data, especially in team sports. By their direct inclusion of different time length of tactical patterns, they open up new opportunities within team sports.

    Objectives: Players in the National Basketball Association (NBA) subject their lower extremities to significant repetitive loading during the season as well as during off-season training. Little is known about the incidence and impact of lower extremity bony stress injuries in these athletes. Methods: Using the player injury database maintained by the NBA Players’ Association, all bony stress injuries from 1992 to May 2016 were identified. Those not involving the lower extremity were excluded from the study. Stress fractures and stress reactions were grouped together. Number of games missed due to the injury as well as player statistics including points per game (ppg), assists per game (apg), steals per game (spg), and blocks per game (bpg) were collected from two years prior to the injury to two years after the injury. Results: 76 lower extremity bony stress injuries were identified involving 75 different NBA players with an average player age of 25.4 ± 4.1 years. 55.3% (42/76) involved the foot, 21.1% (16/76) involved the ankle or fibula, 17.1% (13/76) involved the tibia, and 6.6% (5/76) involved either the knee or patella. The majority of injuries occurred in season 82.9% (63/76) with half of the injuries occurring within the first 6 weeks of the season. 38.2% (29/76) of these injuries were managed surgically. An average of 25.1 ± 21.3 games were missed. 19.7% (15/76) of patients who sustained a stress fracture also had a subsequent injury. 29.2% (21/76) of players were not able to return to professional basketball after the season in which the injury was sustained; however, those who were able to return to the same level of play did not see a significant change in performance as measured by ppg, apg, spg, or bpg when comparing the season prior to the injury and either one or two years after the injury. Stress injuries to the foot carried the worst prognosis, 57.1% (12/21) of those unable to return to professional basketball sustained such an injury

    Full Text Available Objectives The primary purpose of our review was to systematically review the evolution of psycho-physiological performance analysis. Our secondary aim was to investigate the role of specific, multi-disciplinary performance indicators to identify future talents in the sport of soccer, handball and basketball. Methods A review protocol was set up in order to avoid individual bias and ensure an efficient searching prodedure. This enabled a search strategy to define which literature was to be included or excluded from our research. Certain inclusion criteria were identified, before performing a search using three electronic databases (Web of Science, ScienceDirect, and Google Scholar and reference lists for English-language articles, published from the year 1980 till 2017. Results The comprehensive search yielded 82 documents to be relevant to our purpose of the study, according to our inclusion criteria criteria, 58 were fully-reviewed and referred to in our study. As we previously expected, the review of related literature resulted investigations involving mostly soccer and basketball players, studies conducted on handball players are significantly fewer. The majority of those studies examined physical performance characteristics via various field test. Conclusions We concluded that further analysis is necessary to identify relevant psycho-physiological performance indicators, in order to properly enhance sports performance in the younger athlete population and in general too. Vienna Test System protocols may offer a great potential to provide valuable information for athletes and their coaches to enhance athletic performance. Future research should focus on specifically identify Vienna Test System test protocols that may be linked to each particular sport.

    Some cases of subarachnoid haemorrhage (SAH) have been associated with vigorous physical activity, including sports. Our research aimed to describe the association between SAH and sports and to identify the types of sports that were more frequently found as precipitating factors in a tertiary single-centre SAH register. We retrieved information from a prospectively collected SAH registry and reviewed discharge notes of acute SAH patients admitted to the Stroke Unit of Hospital de Santa Maria, Lisbon, between 1995 and 2014. Out of 738 patients included in the analysis, 424 (57.5%) cases of SAH were preceded by physical activity. Nine cases (1.2%) were associated with sports, namely running (2 cases), aerobics (2 cases), cycling, body balance, dance, surf and windsurf. Patients with SAH while practicing sports were younger than controls (average age 43.1 vs. 57.0 years; p = 0.007). In 1 patient, there was a report of trauma to the neck. Patients in the sports group only had Hunt and Hess scale grades 1 (11.1%) or 2 (88.9%) at admission, while patients in the control group had a wider distribution in severity. Our findings indicate that SAH precipitated by sports is not very frequent and is uncommonly related to trauma. Patients who suffered SAH associated with sports were younger and apparently had a milder clinical presentation.

    Doping in sports is as old as sports, but it grew considerably during the 20th century with the arrival in stadiums during the 1990s of amphetamines and anabolic steroids as well as such peptide hormones as erythropoietin. The international fight against doping took a giant step forward in 1999 with the creation of the world antidoping agency (WADA). This study is part of that fight. It follows an earlier survey of retail pharmacists in Senegal and aims to evaluate the knowledge about doping of doctors belonging to the Senegalese Association of Sports Medicine and to assess their attitude towards this phenomenon. Its goal is to determine how best to involve them in preventive actions. We conducted a survey in 2001 and randomly selected and interviewed 60 of the 92 doctors in the association. The questionnaire focused on three areas: their knowledge of doping, their attitudes to it, and the means of prevention that they proposed. The results showed that only 11 of the 60 doctors knew the definition of doping and 15% of doctors could not cite any family of doping products. They were aware mainly of testosterone and other anabolic steroids (84.3%), then amphetamines and other stimulants (64.7%), and finally peptide hormones (58.8%). The subjects mentioned blood doping and pharmacological manipulations as forbidden methods. They considered that the four groups of drugs most often used by athletes for doping were, in descending order, anabolic steroids, stimulants, peptide hormones and corticoids. Eighty per cent of doctors think that Senegalese athletes use doping products and that the sports most involved are football, wrestling, track and field and basketball. They also think that doping is a form of drug addiction and a public health problem. Eleven doctors (18%) said they had been contacted for information on use of doping products. The interviewees consider that the three best methods of prevention include information about side effects, unannounced urine and

    Full Text Available Introduction. Each change in the rules of a sport affects the way it is performed. Therefore, changes in regulations require that new training models be developed. The aim of the study was to determine whether FIBA’s introduction of new regulations in the 2010/2011 season pertaining to the dimensions of certain parts of the playing area, which changed the conditions under which the game was played, impacted the offensive actions of the top three teams in the Polish Basketball League. Material and methods. The study analysed qualitative data describing the offences (n = 16,694 performed during 200 matches of the Polish Basketball League, that is the highest-level men’s professional basketball league in Poland, during two periods: the 2009/2010 season (110 matches; n = 9,343 offences, before the regulations were modified, and the 2010/2011 season (90 matches; n = 7,351 offences, after they were changed. The research involved the players of three teams who received the gold, silver, and bronze medals in the final standings of the Polish National Championship in the 2009/2010 season. Results. The study found a statistically significant (p < 0.001 decrease in the overall number of tactical offensive actions of 3.84% and a significant (p < 0.05 5% decrease in the mean number of points scored. A significant (p < 0.05 decrease in half-court offences, amounting to almost 2% was also observed. This offensive system was characterised by a minor shift toward individual offences with the back to the basket and pick-and-roll offences; these changes, however, did not cause an increase in the level of effectiveness. Conclusions. The direction of the changes observed have been determined, which consisted in a reduction in the overall number of offensive actions and a shift in the place where they were completed, from the three-point area in particular, to the two-point area.

    During a national championship, the anthropometric, physiological, and maturation characteristics of 13- to 14-year-old players of elite basketball teams and their association with sport performance were analyzed. Body parameters (weight, height, skinfold thicknesses, and lengths) were measured and physiological capacities assessed by sprint (20 m) and jump tests (i.e., countermovement jump with arm swing). Chronological age (CA) and maturity offset (years from age at peak height velocity; YAPHV) were calculated, and then predicted age at peak height velocity, as the difference between CA and YAPHV. Game performance was assessed with point averages and the performance index rating (PIR). The birth-date distribution of players was biased, those born early in the selection year outnumbering those born later. Anthropometric analysis indicated that players who performed better had longer body lengths. Physiological testing showed that semi-finalists had better sprint performance than quarter-finalists and those players with greater jump capacity scored more points. Early maturation and advanced maturity status were also associated with better PIR and scored points per game. Multiple blockwise regression analysis showed that, among the factors analyzed, YAPHV was the best predictor of basketball performance. In conclusion, around puberty, physical and physiological parameters associated with maturity and CA are important in determining the success of elite basketball players. Consequently, boys who are born in the second half of the year and/or late maturing tend to be marginalized or totally excluded, and not given the chance to play under equal conditions; their careers may then be held back by the relative disadvantage associated with inexperience.

    Resumen

    El calentamiento es utilizado, aceptado y practicado previamente a la realización de una práctica deportiva por la totalidad de sus participantes. Además, es considerado imprescindible para alcanzar un rendimiento óptimo por la mayoría de deportistas. Sin embargo, existe poca evidencia científica que apoye su efectividad. Todo esto, junto con la diversidad de los deportes, hace necesario la estandarización de unas pautas comunes de calentamiento para cada deporte o disciplina deportiva. En cuanto al baloncesto de élite se refiere, hemos encontrado un gran vacío científico que nos gustaría cubrir. Por lo tanto, los objetivos de este artículo son, primero, la realización de una revisión bibliográfica sobre todos los aspectos relacionados con el calentamiento como pueden ser: definición de calentamiento, tipos de calentamientos, beneficios del mismo, estructura que debe seguir (intensidad, duración, recuperación y especificidad, factores que influyen sobre él, estiramientos si o estiramientos no y de qué tipo en el calentamiento. Y segundo, con las conclusiones obtenidas, describir y proponer una metodología de calentamiento competitivo adaptado al baloncesto de alto nivel, para que ésta se convierta en una guía de referencia justificada a la hora de realizar esta fase pre-partido.

Sports injuries have been defined as those occurring when athletes are practicing sports and that result in tissue alterations or damages, affecting the operation of the corresponding structures. Contact sports such as soccer, rugby, martial arts, basketball, handball and hockey generate greater risk of injuries. The probability of lesions is higher during competition than in training.

  1. Applying deep bidirectional LSTM and mixture density network for basketball trajectory prediction

    Data analytics helps basketball teams to create tactics. However, manual data collection and analytics are costly and ineffective. Therefore, we applied a deep bidirectional long short-term memory (BLSTM) and mixture density network (MDN) approach. This model is not only capable of predicting a basketball trajectory based on real data, but it also can generate new trajectory samples. It is an excellent application to help coaches and players decide when and where to shoot. Its structure is particularly suitable for dealing with time series problems. BLSTM receives forward and backward information at the same time, while stacking multiple BLSTMs further increases the learning ability of the model. Combined with BLSTMs, MDN is used to generate a multi-modal distribution of outputs. Thus, the proposed model can, in principle, represent arbitrary conditional probability distributions of output variables. We tested our model with two experiments on three-pointer datasets from NBA SportVu data. In the hit-or-miss classification experiment, the proposed model outperformed other models in terms of the convergence speed and accuracy. In the trajectory generation experiment, eight model-generated trajectories at a given time closely matched real trajectories.

    Coordinative abilities play a very important role in sport. Unfortunately, researchers do not confine appropriate attention to this issue. Therefore, the aim of this study was an attempt at analysing results of the selected coordinative motor abilities: kinesthetic differentiation, quick reaction and spatial orientation. It was intended to find out whether the results of trials determining manifestations of the particular coordinative abilities exhibit any mutual relationships. Forasmuch as a static torque is a parameter determining the level of force components of the ability of kinaesthetic differentiation, it would like to find out whether its maximum level influences the final result. Research was carried out on 20 young basketball players with the use of a torque meter and Fusion Smart Speed System. It was noticed a lack of statistically significant relationships between the results of trials assessing manifestations of the ability of kinaesthetic differentiation, quick reaction and spatial orientation. However, it was noted statistically significant correlation between the maximum static torque and the accuracy of releasing a particular value of a static torque. The accuracy of releasing a particular value of a static torque ought to be classified as a comprehensive ability that comprises manifestations of strength abilities and kinaesthetic differentiation. Presented trials to evaluation manifestations of the selected coordinative abilities could be used by coaches during a training process. Coaches should also focus on the development of muscle strength of the upper body and upper limbs of basketball players.

    To establish the relationship between the acute:chronic workload ratio and lower-extremity overuse injuries in professional basketball players over the course of a competitive season. The acute:chronic workload ratio was determined by calculating the sum of the current week's session rating of perceived exertion of training load (acute load) and dividing it by the average weekly training load over the previous 4 wk (chronic load). All injuries were recorded weekly using a self-report injury questionnaire (Oslo Sports Trauma Research Center Injury Questionnaire 20 ). Workload ratios were modeled against injury data using a logistic-regression model with unique intercepts for each player. Substantially fewer team members were injured after workload ratios of 1 to 1.49 (36%) than with very low (≤0.5; 54%), low (0.5-0.99; 51%), or high (≥1.5; 59%) workload ratios. The regression model provided unique workload-injury trends for each player, but all mean differences in likelihood of being injured between workload ratios were unclear. Maintaining workload ratios of 1 to 1.5 may be optimal for athlete preparation in professional basketball. An individualized approach to modeling and monitoring the training load-injury relationship, along with a symptom-based injury-surveillance method, should help coaches and performance staff with individualized training-load planning and prescription and with developing athlete-specific recovery and rehabilitation strategies.

    The present study was designed to evaluate the plasma markers of reactive oxygen species (ROS) activity and cytokines, and their relationship with thiol redox status of basketball players during training. Sixteen professional players of the Polish Basketball Extraleague participated in the study. The study was performed during the preparatory period and the play-off round. Markers of ROS activity (lipid peroxidation TBARS, protein carbonylation PC) and reduced glutathione (GSH) demonstrated regularity over time, i.e. TBARS, PC and GSH were elevated at the beginning and decreased at the end of training periods. Oxidized glutathione (GSSG) was not affected by exercise training. Thiol redox status (GSH(total)-2GSSG/GSSG) correlated with TBARS and PC in both training periods. The level of interleukin-6 (IL-6) was increased and positively correlated with thiol redox (r=0.423) in the preparatory period, whereas tumor necrosis factor alpha (TNFalpha) was increased and inversely correlated with thiol redox (r= 0.509) in the play-off round. The present study showed significant shifts in markers of ROS activity, thiol redox status and inflammatory mediators (IL-6, TNFalpha) following professional sport training as well as correlation between changes in thiol redox and cytokine response.

Every devising, selecting and applying specific tactics should satisfy two main objectives, to: be the greater surprise and provide adequate "response" to the opponent's tactics. The possibility of surprising opponent is primarily associated with the phase of defense, till firstly from an offense is expected to find and implement an adequate solution ("response". Prerequisite that this defense could be successfully adopted is that the players (they know, and they can play quality individual defense (one - on - one. Another prerequisite is that the basketball players fully adopted the principles of the system: zone pressing and "man to man" (variations of "pressing" on the full court. The defense in the foul court is, even more demanding because of the space that is defended, which allows players to adapt to the possible, at least the first time, adequate "response" on offense.

    In basketball, every time the offense produces a shot opportunity the player with the ball must decide whether the shot is worth taking. In this article, I explore the question of when a team should shoot and when they should pass up the shot by considering a simple theoretical model of the shot selection process, in which the quality of shot opportunities generated by the offense is assumed to fall randomly within a uniform distribution. Within this model I derive an answer to the question “how likely must the shot be to go in before the player should take it?” and I show that this lower cutoff for shot quality depends crucially on the number of shot opportunities remaining (say, before the shot clock expires), with larger demanding that only higher-quality shots should be taken. The function is also derived in the presence of a finite turnover rate and used to predict the shooting rate of an optimal-shooting team as a function of time. The theoretical prediction for the optimal shooting rate is compared to data from the National Basketball Association (NBA). The comparison highlights some limitations of the theoretical model, while also suggesting that NBA teams may be overly reluctant to shoot the ball early in the shot clock. PMID:22295109

    This study investigated whether anthropometric characteristics, generic and specific sprinting, agility, strength, and endurance capacity could differentiate between First-Division and Third-Division wheelchair basketball (WB) players. A First-Division WB team (n = 8; age = 36.05 ± 8.25 years, sitting body height = 91.38 ± 4.24 cm, body mass = 79.80 ± 12.63 kg) and a Third-Division WB team (n = 11; age = 31.10 ± 6.37 years, sitting body height = 85.56 ± 6.48 cm, body mass = 71.18 ± 17.63 kg) participated in the study. Wheelchair sprint, agility, strength, and endurance tests were performed. The First-Division team was faster (8.7%) in 20 m without the ball, more agile (13-22%), stronger (18-33%), covered more distance (20%) in the endurance test, and presented higher values of rate of perceived exertion for the exercise load (48%) than the Third-Division team. Moreover, the individual 20-m sprint time values correlated inversely with the individual strength/power values (from r = -0.54 to -0.77, p ≤ 0.05, n = 19). Wheelchair basketball coaches should structure strength and conditioning training to improve sprint and agility and evaluate players accordingly, so that they can receive appropriate training stimuli to match the physiological demands of their competitive level.

    Full Text Available The present paper intends to link positive influence of the evolution in rules and the rising reduction casualty with the basketball game dynamics. Throughout a metaphoric perspective it assumes that casualty factors were somehow covered up since the game invention and they were somehow sleepy during the game evolution. This metaphoric point is justified with an historical analysis to Naismith’s goals, presuming the game was created and reinforced by the evolutionary trends of his rules across the time. It was concluded that casualty role in basketball performance was controlled by an evolutionary direction, where the value of merit, ability and expertise are seen as determinants of basketball dynamics.

    The purpose of this study was to examine the effects of prolonged basketball skills training on maximal aerobic power, isokinetic strength, joint mobility, and body fat percentage, in young basketball players, and controls of the same age. Twenty basketball players and 18 control boys participated in the study. Basketball players participated both in their school's physical education program and in a children's basketball team training program. Controls participated only in their school's physical education program. All subjects were tested every 6 months (18 months total, 11(1/2), 12, 12(1/2), 13 years old) for VO(2)max, peak torque values of the quadriceps and hamstrings at 180 and 300 degrees x s(-1) and range of motion of the knee and hip joints. Body fat percentage was assessed at the beginning and the end of the experimental period. Results showed that the basketball group had lower heart rate values in all ages and higher VO(2) values in the initial test compared with the control in submaximal intensity. The VO(2)max was altered in both groups on the final test, when compared to the initial test. However, the basketball group had a higher VO(2)max on each of the 6-month follow-up measurements, compared to the control group (p trained group had significantly lower percentage body fat values, compared to controls. In conclusion, regular basketball training increased aerobic power and decreased body fat percentage of prepubescent boys, while it did not affect muscle strength and joint mobility of the lower limbs. The major implication suggested by the findings of the present study is that, in order to improve the basic physical components, specific training procedures should be incorporated during the basketball training sessions. It is recommended that all children should be involved in some type of cardiovascular and resistance training program.

    Full Text Available In 2013, Mark Cuban, the team owner of Dallas Mavericks of the National Basketball Association (NBA, announced that he would consider selecting female basketball player Brittney Griner to play for his professional men’s team. Within 24 hours after ESPN posted an online article reporting Mark Cuban’s statement, 921 online comments were posted in response. This study analyzes these comments to investigate the pervasive sexism and gender discrimination found in online sporting news arenas. It investigates how Brittney Griner’s sex, gender, and athletic ability became subjects of scrutiny and debate in these online comments and how discriminatory comments about Griner were routinely extended to all female athletes and to women even outside of sport. By examining the online backlash against Mark Cuban’s proposal, this paper investigates the maintenance of sex segregation in professional sport and the systemic devaluing of female athletes and privileging of male athletes that upholds it.

    Sport activity is an important issue in many patients with a pacemaker either because they performed sport activities before pacemaker implantation to reduce the cardiovascular risk or to improve the course of an underlying cardiovascular disease (e.g. coronary artery disease, heart failure) by sports. Compared to patients with an implantable cardioverter defibrillator (ICD) the risks from underlying cardiovascular disease (e.g. ischemia, heart failure), arrhythmia, lead dysfunction or inappropriate therapy are less important or absent. Sport is contraindicated in dyspnea at rest, acute heart failure, new complex arrhythmia, acute myocarditis and acute myocardial infarction, valvular disease with indications for intervention and surgery and comorbidities which prevent physical activity. Patients with underlying cardiovascular disease (including hypertension) should preferably perform types and levels of physical activity that are aerobic (with dynamic exercise) such as running, swimming, cycling instead of sport with high anaerobic demands and high muscular workload. In heart failure, studies demonstrated advantages of isometric sport that increases the amount of muscle, thereby preventing cardiac cachexia. Sport with a risk of blows to the chest or physical contact (e.g. boxing, rugby, martial arts) should be avoided. Implantation, programming and follow-up should respect specific precautions to allow optimal physical activity with a pacemaker including implantation of bipolar leads on the side contralateral to the dominant hand, individual programming of the upper sensor and tracking rate and regular exercise testing.

    Full Text Available Background: Determining somatic models and profiles in young athletes has recently become a fundamental element in selecting basketball playing positions. The aim of this study was to assess the relationship between the body build of young and adult elite male basketball players at different playing positions. Methods: Participants consisted of 35 young (age: 14.09 ± 0.30 years, n = 35 and 35 adult professional basketball players (age: 24.45 ± 5.40 years, n = 35 competing in elite leagues. The anthropometric characteristics assessed included body mass, body height, skinfolds, somatotypes, girths, and breadths. Results: The centers in both age groups were significantly taller and heavier (p < 0.001 compared to forwards and guards. The greatest difference between categories were in the guards’ personal height (from 169.36 to 186.68 = 17.32 cm. The guards from the professional team were closest in height to the forwards (difference = 7.17 cm compared to young players where the difference between guards and forwards was 13.23 cm. Young competitors were more ectomorphic (2.12-3.75-4.17, while professional players were more mesomorphic (2.26-4.57-3.04. Significant criteria for center selection at professional level seems to be personal height and arm span ratio. Conclusions: The results indicate that the selection for basketball playing positions should include the analysis of body height and mass, shoulder breadth, humerus breadth, femur breadth and specifically for centers the difference between personal the height and arm span.

J Strength Cond Res 32(2): 396-408, 2018-The National Basketball Association (NBA) Draft Combine is an annual event where prospective players are evaluated in terms of their athletic abilities and basketball skills. Data collected at the Combine should help NBA teams select right the players for the upcoming NBA draft; however, its value for predicting future performance of players has not been examined. This study investigated predictive validity of the NBA Draft Combine on future performance of basketball players. We performed a principal component analysis (PCA) on the 2010-2015 Combine data to reduce correlated variables (N = 234), a correlation analysis on the Combine data and future on-court performance to examine relationships (maximum pairwise N = 217), and a robust principal component regression (PCR) analysis to predict first-year and 3-year on-court performance from the Combine measures (N = 148 and 127, respectively). Three components were identified within the Combine data through PCA (= Combine subscales): length-size, power-quickness, and upper-body strength. As per the correlation analysis, the individual Combine items for anthropometrics, including height without shoes, standing reach, weight, wingspan, and hand length, as well as the Combine subscale of length-size, had positive, medium-to-large-sized correlations (r = 0.313-0.545) with defensive performance quantified by Defensive Box Plus/Minus. The robust PCR analysis showed that the Combine subscale of length-size was a predictor most significantly associated with future on-court performance (p ≤ 0.05), including Win Shares, Box Plus/Minus, and Value Over Replacement Player, followed by upper-body strength. In conclusion, the NBA Draft Combine has value for predicting future performance of players.

    Sprinting and jumping are two common and important components of high-level sport performance. The weight-bearing dorsiflexion test (WB-DF) and Star Excursion Balance Test (SEBT) are tools developed to identify athletes at risk for lower extremity injury and may be related to running and jumping performance among athletes. The purposes of the present study were: 1) to identify any relationships between functional movement tests (WB-DF and SEBT) and performance tests (jumping, sprinting and changing direction); 2) to examine any relationships between asymmetries in functional movements and performance tests. Descriptive cohort study. Fifteen elite male basketball players (age: 15.4 ± 0.9 years) were assessed during a three-week period to determine the reliability of functional screening tools and performance tests and to examine the relationships between these tests. Relative (intraclass correlation coefficient) and absolute (coefficient of variation) reliability were used to assess the reproducibility of the tests. Significant correlations were detected between certain functional movement tests and performance tests. Both left and right excursion composite scores related to slower performance times in sprint testing, demonstrating that greater dynamic reach relates to decreased quickness and acceleration among these elite basketball athletes. The various relationships between dynamic functional movement testing, speed, and jump performance provide guidance for the strength and conditioning professional when conducting and evaluating data in an effort to improve performance and reduce risk of injury. The results of the present study suggest that these functional and performance tests do not measure the same components of human movement, and could be paired as outcome measures for the clinical and sport assessment of lower extremity function. 2b.

    Details of serious injuries to children ≤16 yrs. of age that necessitated urgent surgical intervention by the Department of Pediatric Surgery of the University Hospital of Lausanne, Switzerland were recorded into a database registry. Some 15 110 entries listed the precise time of injury, and 3114 (20.6%) of these resulted from participating in sport-associated activities. Time-of-day, day-of-week and month-of-year differences in the total number of children's accidental sport injuries (CASI) were validated. Time-of-day patterns were substantiated for "All Sports", for both boys and girls 5-16 yrs. of age, with more boys than girls experiencing incidents at almost every clock hour. Moreover, they were substantiated for this age group for each of the six different considered individual and team CASI categories - Physical Exercises at School; Bicycle Riding; Roller Skating and Skateboarding; Snow Skiing, Sledding, and Tobogganing; Soccer; and Basketball - for which sample sizes were sufficiently large (n > 230) to perform statistical assessment by ANOVA, t-test and/or cosinor analyses. CASI happened primarily between 06:00 and 17:00 h and rarely evening or overnight. Features - specific clock-time and number of peaks and troughs - of the CASI daily curve pattern of the individual six sport categories differed somewhat; nonetheless, excess or greatest number of CASI typically happened between 12:00 and 14:00 h, even when summertime and other scheduled school and family vacation periods were taken into account. Time-of-day and day-of-week patterns in the boy/girl sex ratio were also validated, with midday and Friday/Saturday peaks, respectively. We hypothesize the prominent 24 h patterns of CASI of 5-16 yr. olds, in particular, are representative of a combination of several determinants. These include exogenous periodic and cyclic environmental and sociocultural phenomena, genetic sex-related traits, plus endogenous circadian cognitive and physiologic rhythms

    Ankle sprains due to landing on an opponent's foot are common in basketball. There is no analysis to date that provides a quantification of this injury mechanism. The aim of this study was to quantify the kinematics of this specific injury mechanism and relate this to lateral ankle ligament biomechanics. Case series. The model-based image-matching technique was used to quantify calcaneo-fibular-talar kinematics during four ankle inversion sprain injury incidents in televised NBA basketball games. The four incidents follow the same injury pattern in which the players of interest step onto an opponent's foot with significant inversion and a diagnosed ankle injury. A geometric analysis was performed to calculate the in vivo ligament strains and strain rates for the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL). Despite the controlled selection of cases, the results show that there are two distinct injury mechanisms: sudden inversion and internal rotation with low levels of plantarflexion; and a similar mechanism without internal rotation. The first of these mechanisms results in high ATFL and CFL strains, whereas the second of these strains the CFL in isolation. The injury mechanism combined with measures of the ligament injury in terms of percentage of strain to failure correlate directly with the severity of the injury quantified by return-to-sport. The opportunity to control excessive internal rotation through proprioceptive training and/or prophylactic footwear or bracing could be utilised to reduce the severity of common ankle injuries in basketball.

    This study aimed (1) to profile the plantar loading characteristics when performing the basketball lay-up in a realistic setting and (2) to determine the number of trials necessary to establish a stable mean for plantar loading variables during the lay-up. Thirteen university male basketball players [age: 23.0 (1.4) years, height: 1.75 (0.05) m, mass: 68.4 (8.6) kg] performed ten successful basketball lay-ups from a stationary position. Plantar loading variables were recorded using the Novel Pedar-X in-shoe system. Loading variables including peak force, peak pressure, and pressure-time integral were extracted from eight foot regions. Performance stability of plantar loading variables during the take-off and landing steps were assessed using the sequential averaging technique and intra-class correlation coefficient (ICC). High plantar loadings were experienced at the heel during the take-off steps, and both the heel and forefoot regions upon landing. The sequential estimation technique revealed a five-eight trial range to achieve a stable mean across all plantar loading variables, whereas ICC analysis was insensitive to inter-trial differences of repeated lay-up performances. Future studies and performance evaluation protocols on plantar loading during basketball lay-ups should include at least eight trials to ensure that the measurements obtained are sufficiently stable.

    Recent player tracking technology provides new information about basketball game performance. The aim of this study was to (i) compare the game performances of all-star and non all-star basketball players from the National Basketball Association (NBA), and (ii) describe the different basketball game performance profiles based on the different game roles. Archival data were obtained from all 2013-2014 regular season games (n = 1230). The variables analyzed included the points per game, minutes played and the game actions recorded by the player tracking system. To accomplish the first aim, the performance per minute of play was analyzed using a descriptive discriminant analysis to identify which variables best predict the all-star and non all-star playing categories. The all-star players showed slower velocities in defense and performed better in elbow touches, defensive rebounds, close touches, close points and pull-up points, possibly due to optimized attention processes that are key for perceiving the required appropriate environmental information. The second aim was addressed using a k-means cluster analysis, with the aim of creating maximal different performance profile groupings. Afterwards, a descriptive discriminant analysis identified which variables best predict the different playing clusters. The results identified different playing profile of performers, particularly related to the game roles of scoring, passing, defensive and all-round game behavior. Coaching staffs may apply this information to different players, while accounting for individual differences and functional variability, to optimize practice planning and, consequently, the game performances of individuals and teams.

    Full Text Available The aim of this study was to compare jump height and kinetic and kinematic com-ponents of countermovement vertical jumps between soccer and basketball players performed in two different arm swing conditions: with arm swing (WAS and without arm swing (NAS. Nine basketball players (21.2 ± 2.9 years; 101.64 ± 14.58 kg; 1.95 ± 0.06 m and nine soccer players (18.2 ± 0.7 years; 77.4 ± 7.58 kg; 1.81 ± 0.07 m performed 12 maximal countermo-vement vertical jumps, including 6 WAS jumps and 6 NAS jumps, on a force platform that recorded the ground reaction force (GRF. The vertical component of the GRF was used to estimate jump height and to calculate the kinematic (duration of eccentric phase, duration of concentric phase, and maximal downward displacement of center of mass and kinetic variables (mean power during the eccentric phase, mean power during the concentric, peak power, and peak force. The results showed no differences in jump height or in kinematic or kinetic variables between basketball and soccer players. In addition, the results showed that the participants of the two groups jumped higher in the WAS condition (0.41 m than in the NAS condition (0.36 m because of a higher peak power (WAS=276.8 W/kg0.67 and NAS=241.3 W/kg0.67 and a longer concentric phase duration (WAS=0.20 s/m0.5 and NAS=0.19 s/m0.5 during WAS jump. These results indicate that the basketball and soccer players studied here showed similar performance and the same kinematic and kinetic pattern in maximal vertical jumps and were comparably affected by the use of arm swing.

    Junior basketball athletes require a well-designed resistance training program to improve their physical development. Lack of expert supervision and resistance training in junior development pathways may be overcome by implementing an online video-based program. The aim of this study was to compare the magnitude of improvement (change) in physical performance and strength and functional movement patterns of junior basketball athletes using either a fully supervised or an online video-based resistance training program. Thirty-eight junior basketball athletes (males, n = 17; age, 14 ± 1 year; height, 1.79 ± 0.10 m; mass, 67 ± 12 kg; females, n = 21; age, 15 ± 1 year; height, 1.70 ± 0.07 m; mass, 62 ± 8 kg) were randomly assigned into a supervised resistance training group (SG, n = 13), video training group (VG, n = 13) or control group (CG, n = 12) and participated in a 6-week controlled experimental trial. Pre- and posttesting included measures of physical performance (20-m sprint, step-in vertical jump, agility, sit and reach, line drill, and Yo-Yo intermittent recovery level 1), strength (15 s push-up and pull-up), and functional movement screening (FMS). Both SG and VG achieved 3-5% ± 2-4% (mean ± 90% confidence limits) greater improvements in several physical performance measures (vertical jump height, 20-m sprint time, and Yo-Yo endurance performance) and a 28 ± 21% greater improvement in push-up strength compared with the CG. The SG attained substantially larger gains in FMS scores over both the VG (12 ± 10%) and CG (13 ± 8%). Video-based training appears to be a viable option to improve physical performance and strength in junior basketball athletes. Qualified supervision is recommended to improve functional movement patterns in junior athletes.

    The aim of the present study was to explore the relationship between stress and sport performance in a controlled setting. The experimental protocol used to induce stress in a basketball free throw was the Trier Social Stress Test (TSST) and its control condition (Placebo-TSST). Participants (n = 19), novice basketball players but trained sportspersons, were exposed to two counterbalanced conditions in a crossover design. They were equipped with sensors to measure movement execution, while salivary cortisol and psychological state were also measured. The task consisted of two sequences of 40 free throws, one before either the TSST or Placebo-TSST and one after. Physiological and psychological measures evidenced that the TSST induced significant stress responses, whereas the Placebo-TSST did not. Shooting performance remained stable after the TSST but decreased after the Placebo-TSST. We found no effect of the TSST or Placebo-TSST on movement execution. A multivariate model of free throw performance demonstrated that timing, smoothness and explosiveness of the movements are more relevant to account for beginner’s behavior than stress-related physiological and psychological states. We conclude that the TSST is a suitable protocol to induce stress responses in sport context, even though the effects on beginners’ free throw performance and execution are small and complex.

    Full Text Available Decision-making play a very important role in basketball. While the game is taking place, players are constantly choosing what to do. In order to carry out this research work, two questions have been formulated: 1 how do high level female basketball players make a decision while they are competing? 2 which key components do they use to make the best decisions? The twelve players who make up the Spanish female basketball team have taken part in this project. They all participated in the 2008 FIBA World Olympic Qualifying Tournament, which took place in Madrid. This tournament allowed them to qualify and take part in the 2008 Olympic Games, where they finished in fifth place. A questionnaire and an interview have been used to make this research possible. The matches of the 2008 FIBA World Olympic Qualifying Tournament have also been analyzed. Those aspects in terms of the team's performance in 1x1 and 2x2 attack situations, and more specifically in pick actions, have been recorded and analyzed. In order to include these data, a system of specific categories and variables has been established. The results show that players are expert on making decisions during the competition. In order to come to this conclusion, their opinions, style of decision-making, as well as the way they move in 1x1 and 2x2 situations, were very useful. This research has also confirmed that decisions made by playmakers, forwards and centers are different.

    There were two aims of this study: first, to investigate physical fitness and match performance differences between under-16 (U16) and under-18 (U18) female basketball players, and second, to evaluate the relationship between physical fitness and game-related performances. Twenty-three young, female, elite Spanish basketball players (16.2 1.2 years) participated in the study. The sample was divided into two groups: U16 and U18 players. The average scores from pre- and post-season physical fitness measurements were used for subsequent analyses. Anthropometric variables were also measured. To evaluate game performance, game-related statistics, including the number of games and minutes played, points, rebounds, assists, steals and blocks per game, were recorded for every competitive match in one season. When anthropometric and physical performance variables were compared between groups, the U18 group demonstrated significantly (pagility, anaerobic power, repeated sprint ability and aerobic power (p ≤ 0.005). These findings can help optimize training programs for young, elite female basketball players.

    The aim of this study was to examine whether the changes in the rules of the game instituted in 2000 have modified the physiological factors of success in basketball. The performances of 8 elite male players and 8 average-level players were compared in order to identify which components of fitness among agility, speed, anaerobic power, anaerobic capacity, and upper body strength were key determinants of performance in modern basketball. Each subject performed 7 tests, including vertical jump (VJ), 20-m sprint, agility T test, suicide sprint, 30-second Wingate anaerobic test (WAnT), isokinetic testing of the knee extensors, and 1 repetition maximum (1RM) bench press test. The statistical difference in the anaerobic performances was assessed by Student's t test. The main results showed that, compared to average-level players, elite-level players achieved significantly better performances in the agility T test (+6.2%), VJ test (+8.8%), peak torques developed by knee extensors (+20.2%), and 1RM bench press (+18.6%, p 0.05). These results emphasized the importance of anaerobic power in modern basketball, whereas anaerobic capacity does not seem to be a key aspect to consider. In this context, coaches are advised to avoid using exercises lasting >/=30 seconds in their physical fitness programs, but instead to focus on short and intense tests such as VJ, agility T test, and sprints over very short distances (5 or 10 m).

    Outcomes associated with arthrodesis of the proximal interphalangeal (PIP) joint in Quarter Horses used for Western performance activities are well documented but little is known regarding outcomes for other types of horses. To identify factors associated with outcomes, including breed and activity, after arthrodesis of the PIP joint in Warmbloods, Thoroughbreds and Quarter Horses. Retrospective case series. Surgical case records of 82 Quarter Horses principally engaged in Western performance and Thoroughbred or Warmblood breeds principally engaged in showing, showjumping and dressage, with arthrodesis of the PIP joint were reviewed. Arthrodesis was performed with either 3 transarticular cortex bone screws placed in lag fashion, a dynamic compression plate (DCP) with 2 transarticular cortex bone screws placed in lag fashion, or a locking compression plate (LCP) with 2 transarticular cortex bone screws placed in lag fashion. Demographic data, clinical presentation, radiographic findings, surgical technique, post operative treatment and complications were recorded. Long-term follow-up was obtained for all 82 horses. Osteoarthritis of the PIP joint was the most common presenting condition requiring arthrodesis, which was performed with either the 3 screw technique (n = 41), DCP fixation (n = 22), or LCP fixation (n = 19). Post operatively, 23/31 (74%) Warmbloods/Thoroughbreds and 44/51 (87%) Quarter Horses achieved successful outcomes. Thirteen of 23 (57%) Warmbloods/Thoroughbreds and 24 of 38 (63%) Quarter Horses, used for athletic performance, returned to successful competition. Within this subgroup of horses engaged in high-level activity, regardless of breed type, horses undergoing hindlimb arthrodesis were significantly more likely to return to successful competition (73%; 33/45) than those with forelimb arthrodesis (25%; 4/16, P = 0.002). Arthrodesis of the PIP joint in Warmbloods/Thoroughbreds and Quarter Horses results in a favourable outcome for return to

    Peak oxygen uptake (VO2peak) in Paralympic sitting sports athletes represents their maximal ability to deliver energy aerobically in an upper-body mode, with values being influenced by sex, disability-related physiological limitations, sport-specific demands, training status and how they are tested. To identify VO2peak values in Paralympic sitting sports, examine between-sports differences and within-sports variations in VO2peak and determine the influence of sex, age, body-mass, disability and test-mode on VO2peak. Systematic literature review and meta-analysis. PubMed, CINAHL, SPORTDiscusTM and EMBASE were systematically searched in October 2016 using relevant medical subject headings, keywords and a Boolean. Studies that assessed VO2peak values in sitting sports athletes with a disability in a laboratory setting were included. Data was extracted and pooled in the different sports disciplines, weighted by the Dersimonian and Laird random effects approach. Quality of the included studies was assessed with a modified version of the Downs and Black checklist by two independent reviewers. Meta-regression and pooled-data multiple regression analyses were performed to assess the influence of sex, age, body-mass, disability, test mode and study quality on VO2peak. Of 6542 retrieved articles, 57 studies reporting VO2peak values in 14 different sitting sports were included in this review. VO2peak values from 771 athletes were used in the data analysis, of which 30% participated in wheelchair basketball, 27% in wheelchair racing, 15% in wheelchair rugby and the remaining 28% in the 11 other disciplines. Fifty-six percent of the athletes had a spinal cord injury and 87% were men. Sports-discipline-averaged VO2peak values ranged from 2.9 L∙min-1 and 45.6 mL∙kg-1∙min-1 in Nordic sit skiing to 1.4 L∙min-1 and 17.3 mL∙kg-1∙min-1 in shooting and 1.3 L∙min-1 and 18.9 mL∙kg-1∙min-1 in wheelchair rugby.

    This study investigates whether a single session of routine morning basketball or volleyball training affects saliva levels of cortisol, alpha-amylase (sAA) and secretory immunoglobulin A (sIgA) in boys aged 14–18 years. Twenty-nine boys who participate in basketball or volleyball training, recruited from the Marcin Gortat’s Athletic Championship School in Lodz, were enrolled in the study. The 90-minute routine exercise program included 15 minutes of warm-up followed by basketball or volleyball practice. Unstimulated saliva samples were collected prior to and immediately after the exercise, and were analysed using ELISA. One training session resulted in a significant increase of sAA concentration in all participants, as well as in the volleyball and basketball subgroups (p=0.00022; p=0.0029; p=0.0011; respectively). Post-exercise cortisol levels were significantly lower than pre-exercise levels (p=0.00002) throughout the group, as well as in the volleyball and basketball subgroups (p=0.0048; p=0.0019; p=0.0048; respectively). The exercise protocol did not significantly affect sIgA level, either in the whole examined group or the volleyball subgroup, however a weak significant increase of sIgA was observed in the basketball subgroup (p=0.046). The routine morning training session comprising a warm-up followed by basketball or volleyball practice seems to activate the sympatho-adrenal-medullary system, with a subsequent increase of alpha-amylase, but does not affect oral immunity in 14-18-year-old boys.

    We investigated the effects of a circadian disadvantage (i.e. playing in a different time zone) on the winning percentages in three major sport leagues in North America: the National Basketball Association, the National Hockey League and the National Football League. We reviewed 5 years of regular season games in the National Basketball Association, National Hockey League and National Football League, and noted the winning percentage of the visiting team depending on the direction of travel (west, east, and same time zone) and game time (day and evening games). T-tests and analysis of variance were performed to evaluate the effects of the circadian disadvantage, its direction, the number of time zones travelled, and the game time on winning percentages in each major league. The results showed an association between the winning percentages and the number of time zones traveled for the away evening games, with a clear disadvantage for the teams travelling westward. There was a significant difference in the teams' winning percentages depending on the travelling direction in the National Basketball Association (F 2,5908  = 16.12, P < 0.0001) and the National Hockey League (F 2,5639  = 4.48, P = 0.011), and a trend was found in the National Football League (F 2,1279  = 2.86, P = 0.058). The effect of the circadian disadvantage transcends the type of sport and needs to be addressed for greater equity among the western and eastern teams in professional sports. These results also highlight the importance of circadian rhythms in sport performance and athletic competitions. © 2017 European Sleep Research Society.

    The effects of playing time on performance changes were examined in National Collegiate Athletic Association Division I women basketball players. Twelve basketball players (age = 20.6 ± 1.5 years; height = 178.0 ± 8.2 cm; weight = 74.1 ± 8.1 kg) were assessed before (PRE) and at the end of the regular basketball season (POST). Assessments included squat power; vertical jump (VJ) power; 20-second lower-body reaction test; 3 line drills; and subjective measures of energy, focus, fatigue, and alertness. Pre- to postseason comparisons were made between starters (28.3 ± 5.2 minutes per game) and nonstarters (NSs) (8.3 ± 5.3 minutes per game). Data were analyzed for clinical significance using an approach based on the magnitude of change. Results revealed that starters were likely to have greater increases in absolute VJ peak power and relative VJ peak power (87.9 and 90.7%, respectively) and they were likely (81.6%) to have a greater average squat power than NSs. Subjective measures of energy, focus, and alertness were possibly (72.9%), very likely (97.3%), and likely (79.2%) to be lower in starters compared with NSs, respectively. Other performance measures showed unclear differences between starters and NSs. Pearson's product-moment correlation analysis revealed significant (p basketball season.

    Full Text Available DESCRIPTION The book introduces the undergraduate psychology student to both academic and professional aspects of Sport and Exercise Psychology. It uses up to date research evidence, established theory and a variety of activities that help the student consider and understand academic and professional aspects of this particular academic discipline. PURPOSE The book aims to provide the undergraduate psychology student with a structured introduction to the subject area and an insight into the theoretical evidence and practical suggestions that underpin what a Sport and Exercise psychologist does. The book also aims to support one term or one semester courses in Sport and Exercise Psychology. It is also appropriate for Masters level courses. FEATURES The book begins with a chapter on applied sports psychology to give the reader an insight into the domain of sport psychology, providing an overview of the techniques that could be used. The next three chapters focus on mood, anxiety and self confidence, which influence performance. This leads on to four chapters that focus on managing psychological states. There is also a chapter on leadership which interestingly includes leadership development in coaches and in athletes. Two chapters focus on the effects of exercise on psychological states, providing a balance between the benefits and potential drawbacks. The final chapter examines the issue of placebo effects. Throughout each chapter there are useful activities than can help the reader's understanding of practical and theoretical issues. These also have practical implications for the work of a Sport and Exercise Psychologist. Key ethical issues are raised on a regular basis throughout the text. The book offers an excellent blend of theory and practical suggestions which are critically discussed thus giving valuable insights regarding the research process and applied practice which is often lacking in the more well known standard textbooks for Sport

    Full Text Available Ethics, as a practical philosophy, is found in essential relationships and relations with other relevant practical disciplines (economics, law, politics, sport, etc.. Every human activity is ethically grounded. Therefore, human ethics, which includes sport ethics, is one of the fundamental criteria for establishing moral relations in different are as of sport life. Sport morale stems from a universally accepted ethics legal principles that aim at maintaining sport spirit based on the Olympics codex and humanity principles, among which are: consciousness and honesty, righteousness, cultural-behavior principle, openness, and the like. Changes in sport (organizational, structural, competition, etc. need to be adequately adjusted to universal, and generally accepted, values. Avoiding deontological ethics inevitably leads to increased sports immorality (referees_ fixing match results, spectators_ aggressive behavior, cheating using for bidden doping, etc.. Thus, projecting and introducing innovations in the field of sport, which, after all, are necessary and unavoidable in all areas of life, including sport, will eventually show its positive results only if the aforementioned aspects of sport ethics are taken into consideration.

  16. Caffeine and sports performance.

    Burke, Louise M

    2008-12-01

    Athletes are among the groups of people who are interested in the effects of caffeine on endurance and exercise capacity. Although many studies have investigated the effect of caffeine ingestion on exercise, not all are suited to draw conclusions regarding caffeine and sports performance. Characteristics of studies that can better explore the issues of athletes include the use of well-trained subjects, conditions that reflect actual practices in sport, and exercise protocols that simulate real-life events. There is a scarcity of field-based studies and investigations involving elite performers. Researchers are encouraged to use statistical analyses that consider the magnitude of changes, and to establish whether these are meaningful to the outcome of sport. The available literature that follows such guidelines suggests that performance benefits can be seen with moderate amounts (~3 mg.kg-1 body mass) of caffeine. Furthermore, these benefits are likely to occur across a range of sports, including endurance events, stop-and-go events (e.g., team and racquet sports), and sports involving sustained high-intensity activity lasting from 1-60 min (e.g., swimming, rowing, and middle and distance running races). The direct effects on single events involving strength and power, such as lifts, throws, and sprints, are unclear. Further studies are needed to better elucidate the range of protocols (timing and amount of doses) that produce benefits and the range of sports to which these may apply. Individual responses, the politics of sport, and the effects of caffeine on other goals, such as sleep, hydration, and refuelling, also need to be considered.

    Sports with high numbers of athletes and acute injuries are an important target for preventive actions at a national level. Both for the health of the athlete and to reduce costs associated with injury. The aim of this study was to identify injuries where injury prevention should focus, in order to have major impact on decreasing acute injury rates at a national level. All athletes in the seven investigated sport federations (automobile sports, basketball, floorball, football (soccer), handball, ice hockey, and motor sports) were insured by the same insurance company. Using this insurance database, the incidence and proportion of acute injuries, and injuries leading to permanent medical impairment (PMI), at each body location, was calculated. Comparisons were made between sports, sex, and age. In total, there were 84 754 registered injuries during the study period (year 2006-2013). Athletes in team sports, except in male ice hockey, had the highest risk to sustain an injury and PMI in the lower limb. Females had higher risk of injury and PMI in the lower limb compared to males, in all sports except in ice hockey. This study recommends that injury prevention at national level should particularly focus on lower limb injuries. In ice hockey and motor sports, head/neck and upper limb injuries also need attention. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    In this paper, we report a retrospective study of 236 patients with facial bone fractures from various sports who were treated at the Department of Plastic and Reconstructive Surgery, Inha University Hospital, Incheon, South Korea, between February 1996 and April 2007. The medical records of these patients were reviewed and analyzed to determine the clinical characteristics and treatment of the sports-related facial bone fractures. The highest frequency of sports-related facial bone fractures was in the age group 11 to 20 years (40.3%); there was a significant male predominance in all age groups (13.75:1). The most common causes of the injury were soccer (38.1%), baseball (16.1%), basketball (12.7%), martial arts (6.4%), and skiing or snowboarding (11%). Fractures of the nasal bone were the most common in all sports; mandible fractures were common in soccer and martial arts, orbital bone fractures were common in baseball, basketball, and ice sports, and fractures of the zygoma were frequently seen in soccer and martial arts. The main causes of the sports injuries were direct body contact (50.8%), and the most commonly associated soft tissue injuries were found in the head and neck regions (92.3%). Nasal bone fractures were the most common (54.2%), and tripod fractures were the most common type of complex injuries (4.2%). The complication rate was 3.0%. Long-term epidemiological data regarding the natural history of sports-related facial bone fractures are important for the evaluation of existing preventative measures and for the development of new methods of injury prevention and treatment.

    Open-skill agility qualities have yet to be described in adult male basketball players. Further, the importance of open- and closed-skill agility for team selection remains unknown. Thus, this study aimed to: 1) describe the open- and closed-skill agility of adult male basketball players; and 2) compare these properties between starting and non-starting players. A cross-sectional between-group design was used. Six starting (playing time: 30.1 ± 8.8 min; age: 30.5 ± 4.8 years; height: 192.1 ± 7.7 cm; body mass: 100.5 ± 15.0 kg; VO(2max): 48.4 ± 6.6 mL∙kg⁻¹∙min⁻¹) and six non-starting (4.3 ± 3.6 min; 21.3 ± 5 years; 185.7 ± 7.4 cm; 94.4 ± 17.9 kg; 50.6 ± 3.9 mL∙kg⁻¹∙min⁻¹) state-level basketball players completed multiple trials for the Change of Direction Speed Test (CODST) and Reactive Agility Test (RAT). No statistically significant between-group differences were evident for CODST movement time (starters: 1.652 ± 0.047 s; non-starters: 1.626 ± 0.040 s, P=0.68), RAT response time (starters: 307.5 ± 100.5 ms; non-starters: 426.5 ± 140.7 ms, P=0.12), and RAT decision-making time (starters: 110.7 ± 11.0 ms; non-starters: 147.3 ± 14.2 ms, P=0.08). However, starters (2.001 ± 0.051 s) possessed significantly (P=0.02) faster RAT total movement times than non-starters (2.182 ± 0.040 s). These data support the utility of perceptual and cognitive components of agility performance in distinguishing starting from non-starting players in basketball. Consequently, basketball coaching and conditioning staff should incorporate sport-specific reactive training drills for all players during the annual conditioning plan.

    There is currently little information regarding the ability of metabolic prediction equations to accurately predict oxygen uptake and exercise intensity from heart rate (HR) during intermittent sport. The purpose of the present study was to develop and, cross-validate equations appropriate for accurately predicting oxygen cost (VO2) and energy expenditure from HR during intermittent sport participation. Eleven healthy adult males (19.9±1.1yrs) were recruited to establish the relationship between %VO2peak and %HRmax during low-intensity steady state endurance (END), moderate-intensity interval (MOD) and high intensity-interval exercise (HI), as performed on a cycle ergometer. Three equations (END, MOD, and HI) for predicting %VO2peak based on %HRmax were developed. HR and VO2 were directly measured during basketball games (6 male, 20.8±1.0 yrs; 6 female, 20.0±1.3yrs) and volleyball drills (12 female; 20.8±1.0yrs). Comparisons were made between measured and predicted VO2 and energy expenditure using the 3 equations developed and 2 previously published equations. The END and MOD equations accurately predicted VO2 and energy expenditure, while the HI equation underestimated, and the previously published equations systematically overestimated VO2 and energy expenditure. Intermittent sport VO2 and energy expenditure can be accurately predicted from heart rate data using either the END (%VO2peak=%HRmax x 1.008-17.17) or MOD (%VO2peak=%HRmax x 1.2-32) equations. These 2 simple equations provide an accessible and cost-effective method for accurate estimation of exercise intensity and energy expenditure during intermittent sport.

    The aim of the present study was to identify the game-related statistics that allow discriminating between starters and nonstarter players in women’s basketball when related to winning or losing games and best or worst teams. The sample comprised all 216 regular season games from the 2005 Women’s National Basketball Association League (WNBA). The game-related statistics included were 2- and 3- point field-goals (both successful and unsuccessful), free-throws (both successful and unsuccessful), defensive and offensive rebounds, assists, blocks, fouls, steals, turnovers and minutes played. Results from multivariate analysis showed that when best teams won, the discriminant game-related statistics were successful 2-point field-goals (SC = 0.47), successful free-throws (SC = 0.44), fouls (SC = -0.41), assists (SC = 0.37), and defensive rebounds (SC = 0.37). When the worst teams won, the discriminant game-related statistics were successful 2-point field- goals (SC = 0.37), successful free-throws (SC = 0.45), assists (SC = 0.58), and steals (SC = 0.35). The results showed that the successful 2-point field-goals, successful free-throws and the assists were the most powerful variables discriminating between starters and nonstarters. These specific characteristics helped to point out the importance of starters’ players shooting and passing ability during competitions. Key points The players’ game-related statistical profile varied according to team status, game outcome and team quality in women’s basketball. The results of this work help to point out the different player’s performance described in women’s basketball compared with men’s basketball. The results obtained enhance the importance of starters and nonstarters contribution to team’s performance in different game contexts. Results showed the power of successful 2-point field-goals, successful free-throws and assists discriminating between starters and nonstarters in all the analyses. PMID:24149538

    This article reviews a series of studies (n = 51) examining physical attributes, physiological characteristics, on-court performances and nutritional strategies of female and male elite basketball players. These studies included relevant information on physical and physiological variables, such as height, weight, somatotype, relative size, aerobic profile, strength, anaerobic power, agility and speed. Six main findings emerged from our review: (i) differences in physical attributes exist among playing positions and skill levels (e.g. guards tend to be lighter, shorter and more mesomorphic than centres); (ii) maximum aerobic capacity (VO(2max)) values of female and male players are 44.0-54.0 and 50-60 mLO(2)/kg/min, respectively; (iii) male and female players of higher skill levels tend to have higher vertical jump values; (iv) the more skilled female and male players are faster and more agile than the less skilled players; (v) guards tend to perform more high-intensity movements during game play compared with forwards and centres; and (vi) a water deficit of 2% of bodyweight can lead to reduced physical and mental performance during an actual game. Five limitations associated with the testing protocols used in the studies are outlined, among them the lack of a longitudinal approach, lack of tests performed under physical exertion conditions, and lack of studies using a time-motion analysis. In addition, three practical recommendations for the basketball coach and the strength and conditioning coach are presented. It is concluded that the data emerging from these studies, combined with the knowledge already obtained from the studies on physical and physiological characteristics of elite basketball players, should be applied by basketball and strength and conditioning coaches when planning training programmes for elite basketball players.

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

    The purpose of this case study is to establish how a gradual increase in fatigue affects the position of the arms and shoulders during a long shot in a basketball game. For this purpose, Primoz Brezec, an elite National Basketball Association player, performed a total of 7 series of 20 shots from a distance of 7.24 m. The subject performed a special basketball motor task between individual series' of shots. The fatigue gradually increased with each motor task, and in the meantime, the subject's heart rate (HR) and blood lactate concentration (LA) were measured. The height of each jump during the shot at the basket was measured, and all shots were recorded using a system of 3 digital cameras operating at a frequency of 50 Hz. Thereafter, a kinematic analysis was applied to calculate the height of the shoulder and wrist of the release arm, as well as the elbow and upper arm angles, with regard to the vertical line. The study results reveal statistically significant differences (p basketball coaches and basketball conditioning coaches to include moderate- and high-intensity exercise in their shooting practice sessions.

    2016-09-01

    Aquatic sports are included in the top list of risky practices as the environment per se carries a possibility of death by drowning if not rescued in time. Not only are aquatic sports related to a high risk of death, but also all sports practiced on the water, over the water and on ice. Whatever the reason a person is in the water, drowning carries a higher possibility of death if the individual is unable to cope with the water situation, which may simply be caused by an inability to stay afloat and get out of the water or by an injury or disease that may lead to physical inability or unconsciousness. The competitive nature of sports is a common pathway that leads the sports person to exceed their ability to cope with the environment or simply misjudge their physical capability. Drowning involves some principles and medical interventions that are rarely found in other medical situations as it occurs in a deceptively hostile environment that may not seem dangerous. Therefore, it is essential that health professionals are aware of the complete sequence of action in drowning. This article focuses on the pulmonary injury in sports and recreational activities where drowning plays the major role. Copyright ©ERS 2016.

    This themed issue of the British Journal of Pharmacology has been compiled and edited by Ian McGrath, Regius Professor of Physiology at University of Glasgow and David Cowan, Director of the Drug Control Centre at King's College London. It contains 11 articles covering the mechanisms of action of the major groups of drugs used illicitly in sport. The articles, written by experts in how drugs work, set out where drugs can or cannot affect sporting performance, how this relates to their legitimate medicinal use, their other detrimental effects and how they can be detected. Publication coincides with Olympic year, when sport is highlighted in the public mind and much speculation is made concerning the use of drugs. The articles provide a framework of expert, accurate knowledge to inform and facilitate these debates and to help to overcome the ill-informed and dangerous anecdotal information by which sports men and women are persuaded to misuse drugs in the mistaken belief that this will improve their performance without present or future ill effects. A unique article is included by the Spedding brothers, Mike with a long career in drug discovery and Charlie, the 1984 Los Angeles Olympic Marathon Bronze Medallist and still the English National Marathon record holder. From their unique experience, they describe the insidious and unfair way that drug-assisted performance undermines the ethos of sport and endangers the vital place of sport in maintaining the health of the population.

    The purpose of this study was twofold. Firstly to examine the relations between the different constructs that defines Nicholls' Achievement Goal Theory and Deci and Ryan's self-determination theory. Secondly to analyse the differences that exist between them with respect to the socio-demographic variables gender and age. A sample of 292 federated basketball players from the Region of Murcia (Spain) with ages between 14 and 18 years old was used. In addition, Castilian versions of The Perception of Success Questionnaire (POSQ) and the Sports Motivational Scale (SMS) were administered. Three statistical analyses were employed, a descriptive analysis, a correlation analysis and a regression analysis. The results showed a positive relation between ego orientation, extrinsic motivation and amotivation. The motivational relations between both theories and the differences with respect to gender and age are discussed. We have found out that mainly gender and also age differences are strong predictors of ego orientation, extrinsic motivation of external regulation and amotivation. We can also confirm that extrinsic motivation of external regulation positively predicts ego orientation and a decrease of task orientation. The results ratify the use of the Spanish version of the SMS to measure different types of motivation within the sports context.

    About 5% of all school children are seriously injured during physical education every year. Because of its influence on children's attitude toward sports and the economic aspects, an evaluation of causes and medical consequences is necessary. In this study, 213 school sports accidents were investigated. Besides diagnosis, the localization of injuries, as well as the duration of the sick leave were documented. Average age of injured students was 13 years. Most of the injured students blamed themselves for the accident. The most common injuries were sprains, contusions, and fractures. Main reasons for the accidents were faults in basic motion training. Playing soccer and basketball were the most frequent reasons for injuries. The upper extremity was more frequently involved than the lower extremity. Sports physicians and teachers should work out a program outlining the individual needs and capabilities of the injured students to reintegrate them into physical education.

    The forecasting of talented players is a crucial aspect of building a successful sports franchise and professional sports invest significant resources in making player choices in sport drafts. The current study examined the relationship between career performance (i.e. games played) and draft round for the National Football League, National Hockey League, National Basketball League, and Major League Baseball for players drafted from 1980 to 1989 (n = 4874) against the assumption of a linear relationship between performance and draft round (i.e. that players with the most potential will be selected before players of lower potential). A two-step analysis revealed significant differences in games played across draft rounds (step 1) and a significant negative relationship between draft round and games played (step 2); however, the amount of variance accounted for was relatively low (less than 17%). Results highlight the challenges of accurately evaluating amateur talent. © 2011 John Wiley & Sons A/S.

    Although mouthguards are effective, inexpensive, easy to use, and readily available, this form of protective equipment has been underutilized. "Impulsive delay discounting" (an index of impulsive behavior) among high school athletes may help explain their decision making regarding use of protective equipment such as mouthguards. We investigated the relationship between high school baseball, softball, and basketball players' mouthguard use, impulsive delay discounting, and the precaution adoption process model (a behavior change theory). A convenience sample of boys' and girls' basketball and baseball/softball players at 21 high schools in the Greater Columbus, Ohio, metro area completed a self-administered survey that captured their demographic information, knowledge, attitudes, and beliefs regarding mouthguard use, impulsive delay discounting, and precaution adoption process model stage. We surveyed a total of 1636 students (55.9 % male, 43.8 % female, 0.3 % unknown). Only 12.3 % reported using a mouthguard either every time or sometimes during practice or competition. The primary reasons reported for not wearing mouthguards were they were not required to (65.3 %) and that the athletes could not breathe or talk while wearing one (61.5 %). These reasons were consistent across sex and sport. Most athletes reported that their coaches (87.3 %) and parents (64.5 %) had never talked to them about wearing a mouthguard. Lower precaution adoption process model stage was significantly associated with higher impulsivity (p softball remains low despite the risk of dental injury in these sports. Effective, evidence-based, targeted, and tailored interventions to improve adolescent athletes' use of mouthguards to prevent sports-related dental injuries should be based on the specific behavioral and social factors influencing each athlete's decision making regarding use of mouthguards.

    The aim of the present study was to evaluate the Flemish Sports Compass (FSC), a non-sport-specific generic testing battery. It was hypothesised that a set of 22 tests would have sufficient discriminant power to allocate athletes to their own sport based on a unique combination of test scores. First, discriminant analyses were applied to the 22 tests of anthropometry, physical fitness and motor coordination in 141 boys under age 18 (16.1 ± 0.8 years) and post age at peak height velocity (maturity offset = 2.674 ± 0.926) from Flemish Top Sport Academies for badminton, basketball, gymnastics, handball, judo, soccer, table tennis, triathlon and volleyball. Second, nine sequential discriminant analyses were used to assess the ability of a set of relevant performance characteristics classifying participants and non-participants for the respective sports. Discriminant analyses resulted in a 96.4% correct classification of all participants for the nine different sports. When focusing on relevant performance characteristics, 80.1% to 97.2% of the total test sample was classified correctly within their respective disciplines. The discriminating characteristics were briefly the following: flexibility in gymnastics, explosive lower-limb strength in badminton and volleyball, speed and agility in badminton, judo, soccer and volleyball, upper-body strength in badminton, basketball and gymnastics, cardiorespiratory endurance in triathletes, dribbling skills in handball, basketball and soccer and overhead-throwing skills in badminton and volleyball. The generic talent characteristics of the FSC enable the distinction of adolescent boys according to their particular sport. Implications for talent programmes are discussed.

    Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

    Full Text Available The problem of the research comes from the need for decomposition of a basketball game. The aim was to determine the intervals of active game (“live ball” - term defined by rules and break (“dead ball” - term defined by rules, by analyzing basketball games. In order to obtain the relevant information, basketball games from five different competitions (top level of quality were analyzed. The sample consists of seven games played in the 2006/2007 season: NCAA Play - Off Final game, Adriatic League finals, ULEB Cup final game, Euroleague (2 games and the NBA league (2 games. The most important information gained by this research is that the average interval of active play lasts approximately 47 seconds, while the average break interval lasts approximately 57 seconds. This information is significant for coaches and should be used in planning the training process.

    The objective of this study was to reveal characteristics of muscle strength of upper extremities of wheelchair (WC) basketball players and to ensure more-specific training program preparation. Isokinetic muscle strength of 12 WC basketball players were assessed by ISOMED 2000 device. The assessment protocol was evaluated at 60°/sec velocity with 5 times repeated force and at 240°/sec with 15 times repeated force. This protocol was carried out individually for shoulder flexion-extension and wrist flexion-extension movements at the right and left extremities. The flexion/extension ratio was determined to be outside of the ratios accepted as normal for primarily shoulder joint and for wrist joint. The extension movement was stronger than flexion movement in the shoulders at both velocities and the flexion movement was stronger than ex-tension movement in the wrist. The repeat times where the peak torque occurred were 2-3 repeats at 60°/sec velocity during flexion and extension movements for the wrist and shoulders, and the peak torque occurred at an average of 5-6 repeats in the shoulders at 240°/sec velocity and it occurred at 3-4 repeats in the wrist. The angles where the peak torque of the shoulder flexion and extension occurred varied between 80°-115° at both velocities, and it varied between 5°-30° angles for the wrist. As this study revealed, determination of muscle strength characteristics of WC athletes and especially using objective isokinetic devices will guide the planning of the appropriate training and exercise programs and preventing sports injuries in long term.

    Professional basketball players in the National Basketball Association (NBA) subject their lower extremities to significant repetitive loading during both regular-season and off-season training. Little is known about the incidence of lower extremity bony stress injuries and their impact on return to play and performance in these athletes. Stress injuries of the lower extremity will have significant impact on performance. Case series. Level 4. All bony stress injuries from 2005 to 2015 were identified from the NBA. Number of games missed due to injury and performance statistics were collected from 2 years prior to injury to 2 years after the injury. A linear regression analysis was performed to determine the impact of injury for players who returned to sport. A total of 76 lower extremity bony stress injuries involving 75 NBA players (mean age, 25.4 ± 4.1 years) were identified. Fifty-five percent (42/76) involved the foot, and most injuries occurred during the regular season (82.9%, 63/76), with half occurring within the first 6 weeks. Among players who sustained a fifth metatarsal stress fracture, 42.9% were unable to return to professional play. Players who sustained stress injuries had reduced play performance, specifically related to number of games played ( P = 0.014) and number of steals per game ( P = 0.004). Players who had surgery had significantly better performance at 2 years than those who were managed nonoperatively, independent of the type of injury (β = 4.561; 95% CI, 1.255-7.868). Lower extremity bony stress injuries may significantly affect both short- and long-term player performance and career length. Stress injuries result in decreased player performance, and surgical intervention results in improved performance metrics compared with those treated using conservative methods. Stress injuries result in decreased player performance, and surgical intervention results in improved performance metrics.

    Full Text Available Background In basketball a maximum accuracy at every game intensity is required while shooting. The aim of the present study was to investigate the acute effect of three different drill intensity simulation protocols on jump shot accuracy in expert and junior basketball players. Materials & Methods Eleven expert players (age 26 ± 6 yrs, weight 86 ± 11 kg, height 192 ± 8 cm and ten junior players (age 18 ± 1 yrs, weight 75 ± 12 kg, height 184 ± 9 cm completed three series of twenty jump shots at three different levels of exertion. Counter Movement Jump (CMJ height was also measured after each series of jump shots. Exertion’s intensity was induced manipulating the basketball drills. Heart rate was measured for the whole duration of the tests while the rating of perceived exertion (RPE was collected at the end of each series of shots. Results Heart rate and rating of perceived exertion (RPE were statistically different in the three conditions for both expert and junior players. CMJ height remained almost unchanged in both groups. Jump shot accuracy decreased with increasing drills intensity both in experts and junior players. Expert players showed higher accuracy than junior players for all the three levels of exertion (83% vs 64%, p < 0.001; 75% vs 57%, p < 0.05; 76% vs 60%, p < 0.01. Moreover, for the most demanding level of exertion, experts showed a higher accuracy in the last ten shots compared to the first ten shots (82% vs 70%, p < 0.05. Discussion Experts coped better with the different exertion’s intensities, thus maintaining a higher level of performance. The introduction of technical short bouts of high-intensity sport-specific exercises into skill sessions should be proposed to improve jump shot accuracy during matches.

    Full Text Available Introduction: The aim of this study was to determine differences in morphological characteristics between junior basketball players who have different levels of explosive strength. Methods: The study was conducted on a sample of 84 junior basketball players from (B&H Bosnia and Herzegovina (16-18 years in spring 2013th. The sample of morphological variables consited of: body height, leg length, body weight, upper arm girth in extension, calf girth, triceps skinfold, abdominal skinfold, front thigh skinfold, BMI, the relative body fat percentage. The variables of explosive strength were: vertical jump (VJ, broad jump (BJ and throwing a medicine ball from chest with 3 kg from a standing position. Ward's method of cluster analysis, based on variables of explosive strength we formed four homogeneous groups. Subsequently, using the ANOVA and post-hoc analysis, these groups are differentiated with regard to morphological characteristics. Results: Clusters differed significantly in BJ and VJ. ANOVA found significant differences between clusters in variables of skinfolds, such as the: triceps, abdomen and thigh. Discussion: Defined the influence of morphological variables on explosive strength can be regarded as expected, given that it is primarily about a negative influence of the amount of body fat on relative explosive strength type. This research has shown that junior basketball players in B&H are shorter and ligther when compared to top-level European juniors (Jelicic et al., 2002. Subjects with the lowest skinfolds of the upper limbs and body weight, achieved the best results in the manifestation of relative explosive strength, which has so far rarely been found in samples of trained subjects (Milanese et al., 2010. Possible explanations can be required in a number of training, the intensity and quality of training. Although at this point with certainty, we can't determine on which of these factors involved. This can be confirmed by the results of

    Full Text Available This paper is part of a larger study that identifies who plays sport in Montenegro, and the factors (family, education, economic, religious, cultural stereotypes, and so on that contribute to girls and women’s participation in sport or that limit girls and women’s participation in sport. This study is the first evidencebased research assessing the current status of girls and women’s sport participation in Montenegro, at all institutional levels. Using mixed-methodologies (quantitative assessment, survey data and qualitative focus group interviews this study will determine the numbers of girls and women participating in sport, as compared to boys and men in similar demographic categories, and to examine why girls and women do or do not participate in sport and what are their experiences in sport. Initial findings from the demographic assessment of sport in Montenegro illustrate overall gender disparities in sport participation in the 7 most popular sports; the majority of athletes, coaches, managers and decision-makers, medical staff, referees and sport delegates were men. We found the greatest gender imbalance in soccer and basketball, which were overwhelmingly male-dominated, and the greatest gender parity in handball and volleyball- and in some cases there were more female participants than male participants in these sports. We also examined overall trends in gender and sport participation across the different geographical regions, which were similar. However, there were differences in the types of sports men and women played in the different regions, which may indicate that some sports were more popular, or accepted, or easier to access for women in the central part of the country while other sports were more popular, or accepted or easier to access for women in the northern and southern regions.

    Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance. Copyright © 2011 S.

    2014-05-01

    This review includes the latest findings based on experimental studies addressing sport-specific balance, an area of research that has grown dramatically in recent years. The main objectives of this work were to investigate the postural sway response to different forms of exercise under laboratory and sport-specific conditions, to examine how this effect can vary with expertise, and to provide examples of the association of impaired balance with sport performance and/or increasing risk of injury. In doing so, sports where body balance is one of the limiting factors of performance were analyzed. While there are no significant differences in postural stability between athletes of different specializations and physically active individuals during standing in a standard upright position (e.g., bipedal stance), they have a better ability to maintain balance in specific conditions (e.g., while standing on a narrow area of support). Differences in magnitude of balance impairment after specific exercises (rebound jumps, repeated rotations, etc.) and mainly in speed of its readjustment to baseline are also observed. Besides some evidence on an association of greater postural sway with the increasing risk of injuries, there are many myths related to the negative influence of impaired balance on sport performance. Though this may be true for shooting or archery, findings have shown that in many other sports, highly skilled athletes are able to perform successfully in spite of increased postural sway. These findings may contribute to better understanding of the postural control system under various performance requirements. It may provide useful knowledge for designing training programs for specific sports.

    Prevention of injury among athletes is of paramount importance for sport events. The incidence of injury differs depending on many factors, such as level of competition, type of sport, and standard of surveillance systems. It is our purpose to provide a descriptive epidemiology of a national level competition multi-sports event. During the 2008 Thailand National "Phitsanulok" Games, official medical teams of the various sports completed a report form after each match or competition. The demographic data, type of sport, details of injury or illness, diagnosis, and treatment were collected from the PLKGames 2008 program and analyzed by the Medical Surveillance Committee. There were 14,429 athletes and staff participating in the "Phitsanulok" games. A total of 496 injuries were reported during the competition, of which 300 male and 196 female athletes sustained injuries, resulting in an incidence rate of 4.1 injuries per 100 registered athletes. For all sports, 71, 50 and 38 injuries occurred during Rugby, Handball and Basketball, respectively, which accounted for 32% of all injuries. No injury was reported from many sports, such as table tennis, shooting, dancing, and golf The most common diagnoses were sprains and strains. About half of injuries were caused by contact with another athlete, followed by noncontact (28.6%) and limited-contact incidences (27.6%). According to the number of athletes, the risk of incurring an injury was highest in Pencak Silat, handball, basketball, and rugby football. About half of injuries affected lower extremities, while 135, 53, and 49 injuries involved upper extremity, head & neck, and axial body parts, respectively. The knee and ankle were the most common sites of injury. The data demonstrates a potential risk of injury occurring predominately in full-contact sports and limited-contact sports. The data is potentially useful in developing injury surveillance systems for future sporting events.

    , and technical-tactical activities, and activities with the ball or without it. The cognitive purpose of the paper: was to find and develop the best possible pre-match warm-up structures based on current literature. These data were used to determine a "model" (pattern of optimal warm-up. The practical aim was to formulate guidelines for basketball coaches to develop the warm-up structures, taking into account the duration and proportion of dynamic and static exercises that prepare the body for play. The research material was 12 male players from the basketball team playing in the top tournaments in Poland and in the Tauron Basket League. 11 players were included in the play reliability study, because one of them did not participate in the play and it was impossible to determine his play effectiveness. The team was ranked in the top five of the 2014/2015 league table. The standardized observation method was used in the study. The method consisted in observing people with respect to the purpose of observation, taking into account strictly defined behavioral (reactions categories the researchers were interested in. To evaluate the players’ effectiveness during the match, the original result sheet of the players’ performance based on the Superlak project was used. As a result of the research, no correlation between the type of warm-up performed by the respondents and the player’s reliability during the match was observed. According to authors, the results allow formulating the following conclusions: •    In the Extra-class team, many of the competitors skip the general phase and performed only the specialist phase. There is a division based on the type of exercises (dynamic, static, ball. •    Based on the observation made, the warm-up performed by the Extra-class basketball players did not match the warm-up model resulting from the literature recommendations and it did not affect the player's reliability and performance during the match. •    As a

    This study aimed to assess the nutritional status of women paralympic athletes and their nutritional knowledge. Twenty two players of National Wheelchair Women Basketball Team (15-38 years) participated in this study and answered a questionnaire (76 questions) Players were at sport camp during the assessment where their body weight is measured regularly by the team coach. The waist, hip size and the height of the players who are able to stand have been used for the assessment, while the knee height of the players who are not able to stand have been measured for the study. SPSS 15.0 and BEBIS (Nutritional Data System) have been used for statistical assessment. The average age and sport years as a player of the participants are; respectively; 25.5±7.2 years and 3.9±2.8 years. The average daily energy consumption is 2867.8±523.6 kcal/day. The average proportion of energy, converted from carbohydrate, protein, fat are been calculated as, respectively; 42.7% (5.3±1.5 g/kg/day), 13.3% (1.6±0.3 g/kg/day), 44% (2.5±0.8 g/kg/day). It is also found that Vitamin B1, folic acid, magnesium, iron and fiber have not been consumed enough. The questions about sport nutrition have been mostly answered incorrectly. Athletes have inadequate food consumption and nutrition information. The athletes have to be educated more about nutrition and they should have nutritional counseling support.

    The popularity of active video games (AVGs) has skyrocketed over the last decade. However, research suggests that the most popular AVGs, which rely on synchronous integration between players' activity and game features, fail to promote physical activity outside of the game or for extended periods of engagement. This limitation has led researchers to consider AVGs that involve asynchronous integration of players' ongoing physical activity with game features. Rather than build an AVG de novo, we selected an established sedentary video game uniquely well suited for the incorporation of asynchronous activity: online fantasy sports. The primary aim of this study was to explore the feasibility of a new asynchronous AVG-active fantasy sports-designed to promote physical activity. We conducted two pilot studies of an active fantasy sports game designed to promote physical activity. Participants wore a low cost triaxial accelerometer and participated in an online fantasy baseball (Study 1, n=9, 13-weeks) or fantasy basketball (Study 2, n=10, 17-weeks) league. Privileges within the game were made contingent on meeting weekly physical activity goals (eg, averaging 10,000 steps/day). Across the two studies, the feasibility of integrating physical activity contingent features and privileges into online fantasy sports games was supported. Participants found the active fantasy sports game enjoyable, as or more enjoyable than traditional (sedentary) online fantasy sports (Study 1: t8=4.43, Pgame was cited as a key motivating factor for increasing physical activity. Preliminary evidence supports potential for the active fantasy sports system as a sustainable and scalable intervention for promoting adult physical activity.

    Background: Basketball players are at risk for foot injuries, including Jones fractures. It is unknown how this injury affects the future play and performance of athletes. Hypothesis: National Basketball Association (NBA) players who sustain Jones fractures of the base of the fifth metatarsal have high rates of return to play and do not experience a decrease in performance on return to competition when compared with preinjury and with control-matched peers. Study Design: Retrospective cohort study. Level of Evidence: Level 5. Methods: Data on 26 elite basketball players with Jones fractures over 19 NBA seasons (1994-1995 to 2012-2013) were obtained from injury reports, press releases, player profiles, and online public databases. Variables included age, body mass index (BMI), player position, experience, and surgical treatment. Individual season statistics pre- and postinjury were collected. Twenty-six controls were identified by matched player position, age, and performance statistics. Results: The mean age at the time of injury was 24.8 years, mean BMI was 24.7 kg/m2, and the mean experience prior to injury was 4.1 NBA seasons. Return to previous level of competition was achieved by 85% of athletes. There was no change in player efficiency rating (PER) when pre- and postinjury performance was compared. When compared with controls, no decline in PER measured performance was identified. Conclusion: The majority of NBA players sustaining a Jones fracture return to their preinjury level of competition. These elite athletes demonstrate no decrease in performance on their return to play. Clinical Relevance: Jones fractures are well-studied injuries in terms of etiology, diagnosis, and management. However, the effect of these injuries on future performance of athletes is unknown. Using the findings of our study, orthopaedic surgeons may be better prepared to counsel and educate elite athletes who sustain a Jones fracture. PMID:26627111

    2017-06-08

    The aim of this study was to compare the effects of two different training programs oriented to improve vertical jump performance and leg stiffness in basketball players. Fifty-eight male basketball players were involved, divided into three age groups (Senior, U19 and U17). Subsequently, within any age group, the players were randomly divided into two training groups, respectively performing a 16-week "hang-clean" training program (HCL), and a "half-squat" training program (HSQ), lasting for the same duration. HCL was based on the hang clean exercise and included also jump rope training; HSQ was based on the half squat exercise and included also speed ladder training. The Squat jump (SJ), the Countermovement jump without and with arm swing, and with one step approach (respectively, CMJ, CMJS, and TCMJS) and explosive strength indices obtained with a leg stiffness test were assessed pre- and post-training. In Senior and U19 athletes both training programs involved an improvement of Vertical Jump performance, with some differences between different age groups. Instead, for the U17 players, only the HSQ led to an enhancement of SJ and TCMJS. Significant enhancement of leg stiffness was observed only in U19 and U17 groups after training. The present study showed that the programs based on the hang-clean and half squat allowed to improve explosive strength in basketball training. However, only HSQ was effective for the U17 group. Thus, the present findings demonstrate that specific training programs should be designed according to the age of the players.

    Several authors have analyzed the incidence of injuries in a given sport, but only a few have examined the exposure-related incidence of injuries in different types of sports using the same methodology. Analysis of the incidence, circumstances, and characteristics of injuries in different team sports during the 2004 Olympic Games. Cohort study; Level of evidence, 2. During the 2004 Olympic Games, injuries in 14 team sport tournaments (men's and women's soccer, men's and women's handball, men's and women's basketball, men's and women's field hockey, baseball, softball, men's and women's water polo, and men's and women's volleyball) were analyzed. After each match, the physician of the participating teams or the official medical representative of the sport completed a standardized injury report form. The mean response rate was 93%. A total of 377 injuries were reported from 456 matches, an incidence of 0.8 injuries per match (95% confidence interval, 0.75-0.91) or 54 injuries per 1000 player matches (95% confidence interval, 49-60). Half of all injuries affected the lower extremity; 24% involved the head or neck. The most prevalent diagnoses were head contusion and ankle sprain. On average, 78% of injuries were caused by contact with another player. However, a significantly higher percentage of noncontact (57%) versus contact injuries (37%) was expected to prevent the player from participating in his or her sport. Significantly more injuries in male players (46%) versus female players (35%) were expected to result in absence from match or training. The incidence, diagnosis, and causes of injuries differed substantially between the team sports. The risk of injury in different team sports can be compared using standardized methodology. Even if the incidence and characteristics of injuries are not identical in all sports, prevention of injury and promotion of fair play are relevant topics for almost all team sports.

    Full Text Available Background: Data on agility skills in different populations using pre-planned, change of direction speed tests have previously been reported. However, there are no available data on the agility times of athletes specializing in different sports obtained from Reactive agility tests. Objective: The study compares agility time in groups of athletes of different sports where agility is one of the limiting factors of performance. Methods: Altogether 282 athletes of 14 sport specializations performed the Agility test. Their task was to touch, as fast as possible, with either the left or the right foot, one of four mats located outside each of the four corners of a 0.8 m square. The mats had to be touched in accordance with the location of a stimulus in one of the corners of a screen. The test consisted of 60 visual stimuli with random generation of their location on the screen and a time of generation of 500 to 2,500 ms. The result was a sum of the 32 best agility times. Results: The Agility test has been found to be sensitive in distinguishing groups of athletes of different sport specializations. Table tennis players, badminton players, fencers, tae-kwon-do competitors and karate competitors showed the best agility times (< 350 ms, followed by ice-hockey, tennis, soccer, volleyball, basketball, and hockeyball players (350-400 ms, then aikidoists (400-450 ms, and finally judoists and wrestlers (450-500 ms. Conclusions: The best agility times are in athletes of racquet sports, followed by competitors of combat sports with reactions to visual stimuli, then players of ball sports, and finally competitors of combat sports with reactions to tactile stimuli. Since this is the first study testing agility skills using the Reactive agility test in athletes of different sport specializations, data obtained can be used for comparison of athletes within particular sports.

    2018-01-01

    Full Text Available Background: Several studies showed that the addition of trunk muscle or core stability exercises in the sport training programs is an effective prevention of spinal and other musculoskeletal injuries. Methods: Twelve female basketball players performed supervised five-week exercise program focused on strengthening the trunk muscles. The program was performed three times per week during pre-season. Sorensen test, Fitnessgram Dynamic Curl-Up test, Prone Plank test and Side Bridge test were used to evaluate trunk muscles performance prior to and immediately after the exercise program completion and again after a three-month follow up period. Results: The results of Sorensen test and Prone Plank test significantly improved immediately after the program, but values returned to baseline at follow-up. In contrast, the results of Fitnessgram Dynamic Curl-Up test and Side Bridge test improved significantly with exercise program and remained significantly higher also at follow-up. Conclusions: Exercise program with emphasis on strengthening the trunk and core muscles can improve muscle performance, however, the results deteriorate shortly after program termination. In order to achieve long-term results, trunk and core muscle exercises have to be performed on regular basis, hence they must be incorporated into general strengthening programs of basketball players.

    Until recently, very few controlled studies have examined the prevalence of eating disorders (ED) symptoms among nonelite adolescent female athletes. Moreover, results are mixed and inconclusive. Therefore, the aim of this exploratory study was to examine the prevalence of ED symptoms (underweight, bulimia, drive for thinness, body dissatisfaction) among French nonelite adolescent female athletes (ballet dancers and basketball players) and nonathletes. The sample of adolescent girls (aged between 12 and 16 years), consisted of 43 basketball players, 52 ballet dancers and 49 nonathlete controls. The eating disorder inventory and a demographic-personal information questionnaire (date of birth, experience of ED, week training time, etc.) were filled out by the participants. Additionally, all participants were measured and weighed. The frequencies of ED symptoms were compared between the groups (athletes versus nonathletes, ballet dancers versus basketball players) using a series of χ² tests. The χ² tests did not show significant differences in frequencies of underweight and body dissatisfaction symptoms between nonelite athletes and nonathletes. However, results highlighted a nonsignificant trend toward higher frequency of: (i) drive for thinness (P=0.05) symptoms in nonelite athletes compared with nonathletes, and (ii) bulimia (P=0.06) symptoms in nonathletes compared with nonelite athletes. Additional analyses performed among the sport groups revealed that the prevalence of drive for thinness symptoms was significantly two-fold higher in ballet dancers than basketball players (34.6% versus 16.3%). Nevertheless, no significant differences were found in the frequencies of underweight, bulimia and body dissatisfaction symptoms among the sport groups. This study showed that the frequency of ED symptoms is equivalent in nonelite athletes and nonathletes. However, these nonsignificant results should be interpreted with caution regarding the weak statistical power of

    Full Text Available Jessica L Ford, Kenneth Ildefonso, Megan L Jones, Monna Arvinen-Barrow Department of Kinesiology, Integrative Health Care & Performance Unit, University of Wisconsin-Milwaukee, Milwaukee, WI, USA Abstract: To date, much research has been devoted to understanding how anxiety can affect sport performance, both in practice and in competitive settings. It is well known that sport has the potential for high levels of stress and anxiety, and that practicing and employing a range of psychological strategies can be beneficial in anxiety management. Equally, growing evidence also suggests that anxiety can play a role in sport injury prevention, occurrence, rehabilitation, and the return to sport process. The purpose of this paper is to provide current insights into sport-related anxiety. More specifically, it will provide the reader with definitions and theoretical conceptualizations of sport-related anxiety. This will be followed by making a case for considering the term "performance" to be broader than activities associated with sport-related performance in practice and competition, by including performance activities associated with sport injury prevention, rehabilitation, and the return to sport process. The paper will then highlight the importance of recognizing early signs and symptoms of anxiety, and the potential need for referral. Finally, the conclusions will emphasize the need for appropriate, client-specific, and practitioner competent care for athletes experiencing sport-related anxiety.
