    the number of participants 7.5 persons higher pr. activity compared to club activities. This implies that clubs during peak hours could include more participants. Another possibility to increase utilization is if the management of sport facilities forced sport clubs and other organisers to adapt...... their activities to a smaller amount of floor space, which would make it possible to have more than one activity on the floor at the same time. Hence, to achieve better utilization during prime time, further analysis and research could focus on how activities in sport halls can be adapted to include more......BACKGROUNDDuring peak hours (4.30pm-8pm) demand for timeslots in sport halls in Denmark are high and there are few timeslots available. Further, focus on how public resources are spent most efficient is increasing (Iversen, 2013). This makes it interesting to analyse how utilization could...

    Assessment of the functional capacity of the cardiovascular system is essential in sports medicine. For athletes, the maximal oxygen uptake [Formula: see text] provides valuable information about their aerobic power. In the clinical setting, the (VO(2max)) provides important diagnostic and prognostic information in several clinical populations, such as patients with coronary artery disease or heart failure. Likewise, VO(2max) assessment can be very important to evaluate fitness in asymptomatic adults. Although direct determination of [VO(2max) is the most accurate method, it requires a maximal level of exertion, which brings a higher risk of adverse events in individuals with an intermediate to high risk of cardiovascular problems. Estimation of VO(2max) during submaximal exercise testing can offer a precious alternative. Over the past decades, many protocols have been developed for this purpose. The present review gives an overview of these submaximal protocols and aims to facilitate appropriate test selection in sports, clinical, and home settings. Several factors must be considered when selecting a protocol: (i) The population being tested and its specific needs in terms of safety, supervision, and accuracy and repeatability of the VO(2max) estimation. (ii) The parameters upon which the prediction is based (e.g. heart rate, power output, rating of perceived exertion [RPE]), as well as the need for additional clinically relevant parameters (e.g. blood pressure, ECG). (iii) The appropriate test modality that should meet the above-mentioned requirements should also be in line with the functional mobility of the target population, and depends on the available equipment. In the sports setting, high repeatability is crucial to track training-induced seasonal changes. In the clinical setting, special attention must be paid to the test modality, because multiple physiological parameters often need to be measured during test execution. When estimating VO(2max), one has

    Maximal workload in elite athletes induces increased generation of reactive oxygen/nitrogen species (RONS) and oxidative stress, but the dynamics of RONS production are not fully explored. The aim of our study was to examine the effects of long-term engagement in sports with different energy requirements (aerobic, anaerobic, and aerobic/anaerobic) on oxidative stress parameters during progressive exercise test. Concentrations of lactates, nitric oxide (NO) measured through stabile end product-nitrites (NO(2) (-)), superoxide anion radical (O(2) (•-)), and thiobarbituric reactive substances (TBARS) as index of lipid peroxidation were determined in rest, after maximal workload, and at 4 and 10th min of recovery in blood plasma of top level competitors in rowing, cycling, and taekwondo. Results showed that sportmen had similar concentrations of lactates and O(2) (•-) in rest. Nitrite concentrations in rest were the lowest in taekwondo fighters, while rowers had the highest levels among examined groups. The order of magnitude for TBARS level in the rest was bicycling > taekwondo > rowing. During exercise at maximal intensity, the concentration of lactate significantly elevated to similar levels in all tested sportsmen and they were persistently elevated during recovery period of 4 and 10 min. There were no significant changes in O(2) (•-), nitrite, and TBARS levels neither at the maximum intensity of exercise nor during the recovery period comparing to the rest period in examined individuals. Our results showed that long term different training strategies establish different basal nitrites and lipid peroxidation levels in sportmen. However, progressive exercise does not influence basal nitrite and oxidative stress parameters level neither at maximal load nor during the first 10 min of recovery in sportmen studied.

    During congested fixture periods in team sports, limited recovery time and increased travel hinder the implementation of many recovery strategies; thus alternative methods are required. We examined the impact of a neuromuscular electrical stimulation device on 24-h recovery from an intensive training session in professional players. Twenty-eight professional rugby and football academy players completed this randomised and counter-balanced study, on 2 occasions, separated by 7 days. After baseline perceived soreness, blood (lactate and creatine kinase) and saliva (testosterone and cortisol) samples were collected, players completed a standardised warm-up and baseline countermovement jumps (jump height). Players then completed 60 m × 50 m maximal sprints, with 5 min recovery between efforts. After completing the sprint session, players wore a neuromuscular electrical stimulation device or remained in normal attire (CON) for 8 h. All measures were repeated immediately, 2 and 24-h post-sprint. Player jump height was reduced from baseline at all time points under both conditions; however, at 24-h neuromuscular electrical stimulation was significantly more recovered (mean±SD; neuromuscular electrical stimulation -3.2±3.2 vs. CON -7.2±3.7%; P0.05). Neuromuscular electrical stimulation improves recovery from intensive training in professional team sports players. This strategy offers an easily applied recovery strategy which may have particular application during sleep and travel. Copyright © 2014 Sports Medicine Australia. Published by Elsevier Ltd.

    Full Text Available One important tool for producing specifi c and individualized training intensities is to determine ventilatory threshold (VT, respiratory compensation point (RCP and maximal oxygen uptake (VO2max by means of maximum effort testing. However, in order to be able to interpret these data in a wide-ranging manner, it is also important to understand the metabolic responses that occur during the test as the systems transporting and utilizing O2 and producing CO2 adjust. This review article presents an overview of the metabolic responses that take place during a hypothetical maximum effort test, and the applicability of the fi gures thus obtained to the training of athletes. ABSTRACT A determinação das velocidades atingidas no limiar ventilatório (LV, ponto de compensação respiratório (PCR e consumo máximo de O2 (VO2max através de um teste de esforço máximo, é uma ferramenta importante para a aplicação de intensidades de treinamento específicas e individualizadas. Mas para poder interpretar os dados de uma forma abrangente, também é importante o entendimento das respostas metabólicas presentes no ajuste dos sistemas de transporte e utilização de O2 e produção de CO2 durante a realização do teste. Esta revisão apresenta um panorama das respostas metabólicas que acontecem durante a realização de um teste de esforço máximo hipotético, e a aplicabilidade dos valores obtidos no treinamento de atletas.

    Uncoupling proteins 2 and 3 (UCP2 and UCP3) as mitochondrial electron transporters are involved in regulation of ATP production and energy dissipation as heat. Energy efficiency plays an important role in physical performance, especially in aerobic fitness. The aim of this study was to examine the association between maximal oxygen uptake and genetic variants of the UCP2 and UCP3 genes. The studies were carried out in a group of 154 men and 85 women, professional athletes representing various sports and fitness levels and students of the University of Physical Education in Poznań. Physiological and molecular procedures were used, i.e. direct measurement of maximum oxygen uptake (VO₂max) and analysis of an insertion/deletion (I/D) polymorphism in the 3'untranslated region of exon 8 of the UCP2 gene and a C>T substitution in exon 5 (Y210Y) of the UCP3 gene. No statistically significant associations were found, only certain trends. Insertion allele (I) of the I/D UCP2 and the T allele of the UCP3 gene were favourable in obtaining higher VO₂max level and might be considered as endurance-related alleles.

    We compared the outcome of mating programs based on different evaluation models that included nonadditive genetic effects (dominance and heterozygosity) in addition to additive effects. The additive and dominance marker effects and the values of regression on average heterozygosity were estimated using 632,003 single nucleotide polymorphisms from 7,902 and 7,510 Holstein cows with calving interval and production (milk, fat, and protein yields) records, respectively. Expected progeny values were computed based on the estimated genetic effects and genotype probabilities of hypothetical progeny from matings between the available genotyped cows and the top 50 young genomic bulls. An index combining the traits based on their economic values was developed and used to evaluate the performance of different mating scenarios in terms of dollar profit. We observed that mating programs with nonadditive genetic effects performed better than a model with only additive effects. Mating programs with dominance and heterozygosity effects increased milk, fat, and protein yields by up to 38, 1.57, and 1.21 kg, respectively. The inclusion of dominance and heterozygosity effects decreased calving interval by up to 0.70 d compared with random mating. The average reduction in progeny inbreeding by the inclusion of nonadditive genetic effects in matings compared with random mating was between 0.25 to 1.57 and 0.64 to 1.57 percentage points for calving interval and production traits, respectively. The reduction in inbreeding was accompanied by an average of A$8.42 (Australian dollars) more profit per mating for a model with additive, dominance, and heterozygosity effects compared with random mating. Mate allocations that benefit from nonadditive genetic effects can improve progeny performance only in the generation where it is being implemented, and the gain from specific combining abilities cannot be accumulated over generations.

    Reliable standards of maximal power output in middle-aged and physically active men and women are desirable in sports-medical practice. For this purpose maximal cycle ergometer tests were evaluated in 2038 men and 898 women over 40 years of age (46.8 +/- 6.1 years (mean +/- SD) and 47.5 +/- 6.6 years), who volunteered in a sports-medical check-up and all of whom were active in sports for at least three months in the year preceding the screening (4.3 +/- 3.1 hours/week respectively 3.6 +/- 2.5 hours/week). The range of maximal values for power output (Wmax), heart rate (HRmax), systolic blood pressure (SBPmax) and peak plasma lactate concentrations (PPLa) during progressive cycle ergometer testing are presented for males and females who were divided into groups with a 5-years age difference. Wmax varied with sex (male = 1, female = 0), age (year) and height (cm); Wmax = 65.3 x (sex) + 2.0 x (height) -1.9 x (age) - 67.9 (See = 38.2; r = 0.76). The weighing of different factors that influence performance was also studied by multiple regression analysis to provide improved precision in standards used to interpret exercise tests. In both men and women about half of the variation of Wmax could be explained by the independent variables age, body mass, body fat, smoking habits, vital capacity, heart rate, and physical activity parameters. It is concluded that active involvement in endurance sports and/or the use of the bicycle for transport, contributed substantially to cardiovascular fitness in healthy, middle-aged men and women.

    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.

    Among patients admitted in the emergency department for acute atypical chest pain those with an acute coronary syndrome (ACS) who are mistakenly discharged home have high mortality. A recent retrospective study has demonstrated that multislice computed tomography (MSCT) coronary angiography could improve triage of these patients. We aimed to prospectively confirm these data on patients with a negative screening including maximal treadmill stress. 30 patients discharged from the emergency department after negative screening for an ACS were included. All patients underwent MSCT angiography of the coronary artery. Patients with coronary atheroma on MSCT had an invasive coronary angiography to confirm these findings. Seven patients (23%) had obstructive coronary artery disease on MSCT. Invasive coronary angiography (ICA) confirmed the diagnosis in all patients. In patients with no previously known coronary artery disease admitted to the emergency department with atypical acute chest pain and discharged after negative screening, including maximal treadmill stress test, MSCT coronary angiography is useful for the diagnosis of obstructive coronary artery disease.

    Elderly and low Karnofsky performance status (KPS) patients have been excluded from most prospective trials. This retrospective study investigated glioblastoma treatment outcomes, including those of elderly and low KPS patients, and analyzed the prognostic factors using the medical records of 107 consecutive patients, 59 men and 48 women aged from 21 to 85 years (median 65 years), with newly diagnosed glioblastoma treated at our institute. There were 71 high-risk patients with age >70 years and/or KPS 6 -methylguanine-deoxyribonucleic acid methyltransferase-negative (p=0.027), and more than subtotal removal (p=0.003) were significant prognostic factors. The median postoperative KPS score tended to be better than the preoperative score, even in the high-risk group. We recommend maximal safe resection for glioblastoma patients, even those with advanced age and/or with low KPS scores. (author)

  1. Developing maximal neuromuscular power: Part 1--biological basis of maximal power production.

    Cormie, Prue; McGuigan, Michael R; Newton, Robert U

    2011-01-01

    This series of reviews focuses on the most important neuromuscular function in many sport performances, the ability to generate maximal muscular power. Part 1 focuses on the factors that affect maximal power production, while part 2, which will follow in a forthcoming edition of Sports Medicine, explores the practical application of these findings by reviewing the scientific literature relevant to the development of training programmes that most effectively enhance maximal power production. The ability of the neuromuscular system to generate maximal power is affected by a range of interrelated factors. Maximal muscular power is defined and limited by the force-velocity relationship and affected by the length-tension relationship. The ability to generate maximal power is influenced by the type of muscle action involved and, in particular, the time available to develop force, storage and utilization of elastic energy, interactions of contractile and elastic elements, potentiation of contractile and elastic filaments as well as stretch reflexes. Furthermore, maximal power production is influenced by morphological factors including fibre type contribution to whole muscle area, muscle architectural features and tendon properties as well as neural factors including motor unit recruitment, firing frequency, synchronization and inter-muscular coordination. In addition, acute changes in the muscle environment (i.e. alterations resulting from fatigue, changes in hormone milieu and muscle temperature) impact the ability to generate maximal power. Resistance training has been shown to impact each of these neuromuscular factors in quite specific ways. Therefore, an understanding of the biological basis of maximal power production is essential for developing training programmes that effectively enhance maximal power production in the human.

    The assessment of muscle function is a cornerstone in the management of subjects who have sustained a lateral ankle sprain. The ankle range of motion being relatively small, the use of preloading allows to measure maximal strength throughout the whole amplitude and therefore to better characterize ankle muscles weaknesses. This study aimed to assess muscle strength of the injured and uninjured ankles in subjects with a lateral ankle sprain, to document the timeline of strength recovery, and to determine the influence of sprain grade on strength loss. Maximal torque of the periarticular muscles of the ankle in a concentric mode using a protocol with maximal preloading was tested in 32 male soldiers at 8 weeks and 6 months post-injury. The evertor muscles of the injured ankles were weaker than the uninjured ones at 8 weeks and 6 months post-injury (Pankles at 8 weeks (P=0.0014, effect size=0.52-0.58) while at 6 months, only the subjects with a grade II sprain displayed such weaknesses (Pankle sprain in very active individuals.

    Wearable performance devices and sensors are becoming more readily available to the general population and athletic teams. Advances in technology have allowed individual endurance athletes, sports teams, and physicians to monitor functional movements, workloads, and biometric markers to maximize performance and minimize injury. Movement sensors include pedometers, accelerometers/gyroscopes, and global positioning satellite (GPS) devices. Physiologic sensors include heart rate monitors, sleep monitors, temperature sensors, and integrated sensors. The purpose of this review is to familiarize health care professionals and team physicians with the various available types of wearable sensors, discuss their current utilization, and present future applications in sports medicine. Data were obtained from peer-reviewed literature through a search of the PubMed database. Included studies searched development, outcomes, and validation of wearable performance devices such as GPS, accelerometers, and physiologic monitors in sports. Clinical review. Level 4. Wearable sensors provide a method of monitoring real-time physiologic and movement parameters during training and competitive sports. These parameters can be used to detect position-specific patterns in movement, design more efficient sports-specific training programs for performance optimization, and screen for potential causes of injury. More recent advances in movement sensors have improved accuracy in detecting high-acceleration movements during competitive sports. Wearable devices are valuable instruments for the improvement of sports performance. Evidence for use of these devices in professional sports is still limited. Future developments are needed to establish training protocols using data from wearable devices. © 2015 The Author(s).

    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.

    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.

  20. Brain injury in sports.

    Lloyd, John; Conidi, Frank

    2016-03-01

    Helmets are used for sports, military, and transportation to protect against impact forces and associated injuries. The common belief among end users is that the helmet protects the whole head, including the brain. However, current consensus among biomechanists and sports neurologists indicates that helmets do not provide significant protection against concussion and brain injuries. In this paper the authors present existing scientific evidence on the mechanisms underlying traumatic head and brain injuries, along with a biomechanical evaluation of 21 current and retired football helmets. The National Operating Committee on Standards for Athletic Equipment (NOCSAE) standard test apparatus was modified and validated for impact testing of protective headwear to include the measurement of both linear and angular kinematics. From a drop height of 2.0 m onto a flat steel anvil, each football helmet was impacted 5 times in the occipital area. Skull fracture risk was determined for each of the current varsity football helmets by calculating the percentage reduction in linear acceleration relative to a 140-g skull fracture threshold. Risk of subdural hematoma was determined by calculating the percentage reduction in angular acceleration relative to the bridging vein failure threshold, computed as a function of impact duration. Ranking the helmets according to their performance under these criteria, the authors determined that the Schutt Vengeance performed the best overall. The study findings demonstrated that not all football helmets provide equal or adequate protection against either focal head injuries or traumatic brain injuries. In fact, some of the most popular helmets on the field ranked among the worst. While protection is improving, none of the current or retired varsity football helmets can provide absolute protection against brain injuries, including concussions and subdural hematomas. To maximize protection against head and brain injuries for football players of

    Context: Many coaches, parents, and children believe that the best way to develop elite athletes is for them to participate in only 1 sport from an early age and to play it year-round. However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Evidence Acquisition: Nonsystematic review with critical appraisal of existing literature. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

    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.

    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.

    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.

    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.

  8. [Sport for pacemaker patients].

    Science.gov (United States)

    Israel, C W

    2012-06-01

    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.

  9. Developing maximal neuromuscular power: part 2 - training considerations for improving maximal power production.

    Science.gov (United States)

    Cormie, Prue; McGuigan, Michael R; Newton, Robert U

    2011-02-01

    This series of reviews focuses on the most important neuromuscular function in many sport performances: the ability to generate maximal muscular power. Part 1, published in an earlier issue of Sports Medicine, focused on the factors that affect maximal power production while part 2 explores the practical application of these findings by reviewing the scientific literature relevant to the development of training programmes that most effectively enhance maximal power production. The ability to generate maximal power during complex motor skills is of paramount importance to successful athletic performance across many sports. A crucial issue faced by scientists and coaches is the development of effective and efficient training programmes that improve maximal power production in dynamic, multi-joint movements. Such training is referred to as 'power training' for the purposes of this review. Although further research is required in order to gain a deeper understanding of the optimal training techniques for maximizing power in complex, sports-specific movements and the precise mechanisms underlying adaptation, several key conclusions can be drawn from this review. First, a fundamental relationship exists between strength and power, which dictates that an individual cannot possess a high level of power without first being relatively strong. Thus, enhancing and maintaining maximal strength is essential when considering the long-term development of power. Second, consideration of movement pattern, load and velocity specificity is essential when designing power training programmes. Ballistic, plyometric and weightlifting exercises can be used effectively as primary exercises within a power training programme that enhances maximal power. The loads applied to these exercises will depend on the specific requirements of each particular sport and the type of movement being trained. The use of ballistic exercises with loads ranging from 0% to 50% of one-repetition maximum (1RM) and

Nowadays, human evolution, including his intellectual development, proves the fact that especially the creation manpower and the employment was the solution of all life’s ambitions in society. So, the fact is that in reality, man is the most important capital of the society. Also, in an individual’s life, the practice of sport plays a significant role and that’s why the initiation, the launch and the management of sports complexes activity reveal the existence of specific management features that we will identify and explain in the current study. The aim of the research refers to the elaboration of a theoretical base of the management of the sport complexes, to the pointing of the factors that influence the efficient existence and function of a sport complex in our country and to the determination of the responsibilities that have a manager who directs successfully the activity of the sport complexes. The investigation is based on theoretical methods, such as: scientific documentation, analysis, synthesis, comparison and on empirical research methods, like: study of researched literature and observation. The results of the research indicate the fact that the profitability of a sport complex must assure a particular structure to avoid the bankruptcy risk and also, that the administration of the sport complexes activity must keep in view the reliable functions of the contemporaneous management.

    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

    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.

  2. Caffeine and sports performance.

    Science.gov (United States)

    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.

    Full Text Available The objective of the book is to review comprehensively what is known about the distribution and determinants of injury rates in a variety of individual sports, and to suggest injury prevention measures and guidelines for further research. This book provides comprehensive compilation and critical analysis of epidemiological data over children's individual sports: including equestrian, gymnastics, martial arts, skiing and snowboarding, tennis, track and field, and wrestling. This book encourages coaches and sports administrators to discuss rules, equipment standards, techniques, and athlete conditioning programs. In turn, they can inform parents about the risks and how they can help their children avoid or limit injury in sports. A common, uniform strategy and evidence-based approach to organizing and interpreting the literature is used in all chapters. All the sports-specific chapters are laid out with the same basic headings, so that it is easy for the reader to find common information across chapters. Chapter headings are: 1 Epidemiology of children's individual sports injuries, 2 Equestrian injuries, 2 Gymnastics injuries, 3 Martial arts injuries, 4 Skiing and snowboard injuries, 5 Tennis injuries, 6 Track and field injuries, 7 Wrestling injuries, 8 Injury prevention and future research. Chapter headings include: i Incidence of injury, ii Injury characteristics, iii Injury severity, iv njury risk factors, v Suggestions for injury prevention, vi Suggestions for further research. In each sports-specific chapter, an epidemiological picture has been systematically developed from the data available in prospective cohort, retrospective cohort, case-control, and cross-sectional studies. The tables are numerous, helpful and very useful.

    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.

  10. Determinants of team-sport performance: implications for altitude training by team-sport athletes.

    Bishop, David J; Girard, Olivier

    2013-12-01

    Team sports are increasingly popular, with millions of participants worldwide. Athletes engaged in these sports are required to repeatedly produce skilful actions and maximal or near-maximal efforts (eg, accelerations, changes in pace and direction, sprints, jumps and kicks), interspersed with brief recovery intervals (consisting of rest or low-intensity to moderate-intensity activity), over an extended period of time (1-2 h). While performance in most team sports is dominated by technical and tactical proficiencies, successful team-sport athletes must also have highly-developed, specific, physical capacities. Much effort goes into designing training programmes to improve these physical capacities, with expected benefits for team-sport performance. Recently, some team sports have introduced altitude training in the belief that it can further enhance team-sport physical performance. Until now, however, there is little published evidence showing improved team-sport performance following altitude training, despite the often considerable expense involved. In the absence of such studies, this review will identify important determinants of team-sport physical performance that may be improved by altitude training, with potential benefits for team-sport performance. These determinants can be broadly described as factors that enhance either sprint performance or the ability to recover from maximal or near-maximal efforts. There is some evidence that some of these physical capacities may be enhanced by altitude training, but further research is required to verify that these adaptations occur, that they are greater than what could be achieved by appropriate sea-level training and that they translate to improved team-sport performance.

    Szpilman, David; Orlowski, James P

    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.

    Two ambiguities are noted in the definition of the concept of maximal CP violation. The phase convention ambiguity is overcome by introducing a CP violating phase in the quark mixing matrix U which is invariant under rephasing transformations. The second ambiguity, related to the parametrization of U, is resolved by finding a single empirically viable definition of maximal CP violation when assuming that U does not single out one generation. Considerable improvement in the calculation of nonleptonic weak amplitudes is required to test the conjecture of maximal CP violation. 21 references

    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.

    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.

  3. Sport-specific balance.

    Zemková, Erika

    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.

    were included. The search history spanned from the earliest record until September 2015. Of the eight combat sports searched for, five were represented across 23 studies. Sixteen investigations described maximal strength or neuromuscular power variables, while 19 articles reported anaerobic or aerobic measures. The results indicate that a number of strength, neuromuscular power and anaerobic variables distinguished higher- from lower-level combat sport athletes. However, these differences were less clear when groups were stratified within, rather than between competition grades. Greater aerobic power was generally not present amongst superior combat sport competitors. There appear to be differing physiological profiles between more successful grappling and striking combat sport athletes. This is represented by high-force demands of grappling sports causing an upwards shift of the entire force-velocity relationship driven by an increase in maximal strength. In comparison, smaller increases in maximal force production with more notable enhancements in lighter load, higher velocity actions may better identify superior performance in striking sports. Anaerobic capabilities largely distinguished higher- from lower-level combat sport athletes. In particular, longer-term anaerobic efforts seem to define successful grappling-based athletes, while superior competitors in striking sports tend to show dominance in shorter-term measures when compared with their lower-level counterparts. Given the demand for both forms of combat in MMA, a spectrum of physiological markers may characterize higher-level competitors. Furthermore, the performance profile of successful MMA athletes may differ based on combat sport history or competition strategy.

    The size of sports fields considerably varies from a few meters for table tennis to hundreds of meters for golf. We first show that this size is mainly fixed by the range of the projectile, that is, by the aerodynamic properties of the ball (mass, surface, drag coefficient) and its maximal velocity in the game. This allows us to propose general classifications for sports played with a ball. (paper)

    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.

    The liver is a vital organ and plays a central role in energy exchange, protein synthesis as well as the elimination of waste products from the body. Acute and chronic injury may disturb a variety of liver functions to different degrees. Over the last three decades, the effects of physical activity and competitive sport on the liver have been described by various investigators. These include viral hepatitis and drug-induced liver disorders. Herein, we review acute and chronic liver diseases potentially caused by sport. Team physicians, trainers and others, responsible for the health of athletes, should be familiar with the risk factors, clinical features, and consequences of liver diseases that occur in sports.

    Full Text Available In sport marketing, the word promotion covers a range of interrelated activities. All of these activities are designed to attract attention, stimulate the interest and awareness of consumers, and of course, encourage them to purchase a sport product. Promotion is about communicating with and educating consumers. The purpose of a sport promotional strategy is to build brand loyalty and product credibility, develop image, and position the brand. A promotional strategy is similar to a marketing strategy, but the promotional strategy seeks short-term objectives, both direct and indirect. Promotional objectives usually include increased sales, stimulate impulse buying, raise customer traffic, and present and reinforce image. It also provides information about products and services, publicizes new stores or websites, and creates and enhances customer satisfaction.

    For a long time, badminton was considered to be only a slow and light game for children, a game that is played outdoors and is structurally undemanding.Today, it is not an unknown and unrecognised sport, especially after it was included into the Olympics Games in 1992. Badminton is one of the oldest sports in the world. It is suitable for all ages (for children and elderly equally), women and men and even handicapped persons. Beginners can start playing badminton matches early because the basics are learned quickly. As a recreational activity, badminton is very popular in Zagreb. In the last 10 years, a number of halls specialized for badminton or offering badminton as one of available sports activities have been opened in Zagreb. At present, there are over 70 professional playgrounds for training of top contestants but also for the citizens who can play recreational badminton.

    2015-03-01

    Full Text Available As participation in both amateur and professional sports increases, so does the importance of sports performance and the factors influencing it. Determinants of success in sports can be classified as training, genetic, epigenetic, dietary, motivational, equipment and other environmental factors. The effect of genetics on sports performance and skill has been examined for many years. Autosomal genes, mitochondrial DNA and various genes located in the Y chromosome have all been associated with sports performance. It is not possible to link physical performance to a single genetic polymorphism. Genes that have been most extensively studied in their relation to performance include ACE, ACTN3, ADRA2A, ADRB2, PPARA, PPARGC1A, AMPD1, HIF1A, NOS3, BDKRB2, VEGFR2 and VEGFA. For the time being, genetic screening tests may be useful in determining the weaknesses and strengths of a sportsperson, but not in predicting athletic success.

    Figueroa-O'Farrill, Jose; Hackett-Jones, Emily; Moutsopoulos, George; Simon, Joan

    2009-01-01

    In this paper we give a precise definition of the notion of a maximal superalgebra of certain types of supersymmetric supergravity backgrounds, including the Freund-Rubin backgrounds, and propose a geometric construction extending the well-known construction of its Killing superalgebra. We determine the structure of maximal Lie superalgebras and show that there is a finite number of isomorphism classes, all related via contractions from an orthosymplectic Lie superalgebra. We use the structure theory to show that maximally supersymmetric waves do not possess such a maximal superalgebra, but that the maximally supersymmetric Freund-Rubin backgrounds do. We perform the explicit geometric construction of the maximal superalgebra of AdS 4 X S 7 and find that it is isomorphic to osp(1|32). We propose an algebraic construction of the maximal superalgebra of any background asymptotic to AdS 4 X S 7 and we test this proposal by computing the maximal superalgebra of the M2-brane in its two maximally supersymmetric limits, finding agreement.

    A standing debate in philosophy of sport concerns whether sport can count as art in some sense. But the debate is often conducted at cross purposes. Naysayers insist that no sport is an artform while proponents insist that certain sport performances count as artworks – but these are entirely consistent claims. Both sides make unwarranted assumptions: naysayers are purists about sport and art (no transaesthetic purposes) whereas proponents are tokenists about artforms. Naysayers admit that fig...

    2008-01-01

    Sports and physical activity are transforming, and being transformed by, the societies in which they are practised. From the perspectives of both competitive and non-competitive sports, the complexity of their integration into today's society has led to neither sports federations nor governments being able to manage the safety problem alone. In other words, these agencies, whilst promoting sport and physical activity, deliver policy and practices in an uncoordinated way that largely ignores the need for a concurrent overall policy for sports safety. This article reviews and analyses the possibility of developing an overall sports safety policy from a global viewpoint. Firstly, we describe the role of sports in today's societies and the context within which much sport is delivered. We then discuss global issues related to injury prevention and safety in sports, with practical relevance to this important sector, including an analysis of critical policy issues necessary for the future development of the area and significant safety gains for all. We argue that there is a need to establish the sports injury problem as a critical component of general global health policy agendas, and to introduce sports safety as a mandatory component of all sustainable sports organizations. We conclude that the establishment of an explicit intersection between science and policy making is necessary for the future development of sports and the necessary safety gains required for all participants around the world. The Safe Sports International safety promotion programme is outlined as an example of an international organization active within this arena.

    2017-07-01

    Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures.

    It is argued that data from atmospheric and solar neutrino experiments point strongly to tri-maximal or bi-maximal lepton mixing. While ('optimised') bi-maximal mixing gives an excellent a posteriori fit to the data, tri-maximal mixing is an a priori hypothesis, which is not excluded, taking account of terrestrial matter effects

    Kellmann, M

    2010-10-01

    In sports, the importance of optimizing the recovery-stress state is critical. Effective recovery from intense training loads often faced by elite athletes can often determine sporting success or failure. In recent decades, athletes, coaches, and sport scientists have been keen to find creative, new methods for improving the quality and quantity of training for athletes. These efforts have consistently faced barriers, including overtraining, fatigue, injury, illness, and burnout. Physiological and psychological limits dictate a need for research that addresses the avoidance of overtraining, maximizes recovery, and successfully negotiates the fine line between high and excessive training loads. Monitoring instruments like the Recovery-Stress Questionnaire for Athletes can assist with this research by providing a tool to assess their perceived state of recovery. This article will highlight the importance of recovery for elite athletes and provide an overview of monitoring instruments. © 2010 John Wiley & Sons A/S.

  5. Playing with heart and soul…and genomes: sports implications and applications of personal genomics.

    Wagner, Jennifer K

    2013-01-01

    Whether the integration of genetic/omic technologies in sports contexts will facilitate player success, promote player safety, or spur genetic discrimination depends largely upon the game rules established by those currently designing genomic sports medicine programs. The integration has already begun, but there is not yet a playbook for best practices. Thus far discussions have focused largely on whether the integration would occur and how to prevent the integration from occurring, rather than how it could occur in such a way that maximizes benefits, minimizes risks, and avoids the exacerbation of racial disparities. Previous empirical research has identified members of the personal genomics industry offering sports-related DNA tests, and previous legal research has explored the impact of collective bargaining in professional sports as it relates to the employment protections of the Genetic Information Nondiscrimination Act (GINA). Building upon that research and upon participant observations with specific sports-related DNA tests purchased from four direct-to-consumer companies in 2011 and broader personal genomics (PGx) services, this anthropological, legal, and ethical (ALE) discussion highlights fundamental issues that must be addressed by those developing personal genomic sports medicine programs, either independently or through collaborations with commercial providers. For example, the vulnerability of student-athletes creates a number of issues that require careful, deliberate consideration. More broadly, however, this ALE discussion highlights potential sports-related implications (that ultimately might mitigate or, conversely, exacerbate racial disparities among athletes) of whole exome/genome sequencing conducted by biomedical researchers and clinicians for non-sports purposes. For example, the possibility that exome/genome sequencing of individuals who are considered to be non-patients, asymptomatic, normal, etc. will reveal the presence of variants of

    The use of creatine as a dietary supplement has become increasingly popular over the past several decades. Despite the popularity of creatine, questions remain with regard to dosing, effects on sports performance, and safety. PubMed was searched for articles published between 1980 and January 2017 using the terms creatine, creatine supplementation, sports performance, and dietary supplements. An additional Google search was performed to capture National Collegiate Athletic Association-specific creatine usage data and US dietary supplement and creatine sales. Clinical review. Level 4. Short-term use of creatine is considered safe and without significant adverse effects, although caution should be advised as the number of long-term studies is limited. Suggested dosing is variable, with many different regimens showing benefits. The safety of creatine supplementation has not been studied in children and adolescents. Currently, the scientific literature best supports creatine supplementation for increased performance in short-duration, maximal-intensity resistance training. While creatine appears to be safe and effective for particular settings, whether creatine supplementation leads to improved performance on the field of play remains unknown.

    Full Text Available Abstract Introduction: The risk of injuries related to physical activity and sports may increase if there is predisposition, inappropriate training and/or coach guidance, and absence of sports medicine follow-up. Objective: To assess the frequency of injuries in athletes treated at a physiotherapy center specialized in sports. Methods: For the data collection was carried out the survey of injuries in records of athletes treated in eight years of activities. The data collected included: characteristics of patients, sport, injury kind, injury characteristics and affected body part. Results: From 1090 patient/athlete records, the average age was 25 years old, the athletes were spread across 44 different sports modalities, being the great majority men (75%. The most common type of injury was joint injury, followed by muscular and bone injuries. Chronic injury was the most frequent (47%, while the most common body part injured was the knee, followed by ankle and shoulder. Among all the sports, soccer, futsal, and track and field presented the highest number of injured athletes, respectively. Conclusion: Soccer was the most common sport among the injured athletes, injury kind most frequent was joint injuries and knee was the body part most injured. Chronic injuries were the most common.

  14. When Is a Sprint a Sprint? A Review of the Analysis of Team-Sport Athlete Activity Profile

    Directory of Open Access Journals (Sweden)

    Alice J. Sweeting

    2017-06-01

    Full Text Available The external load of a team-sport athlete can be measured by tracking technologies, including global positioning systems (GPS, local positioning systems (LPS, and vision-based systems. These technologies allow for the calculation of displacement, velocity and acceleration during a match or training session. The accurate quantification of these variables is critical so that meaningful changes in team-sport athlete external load can be detected. High-velocity running, including sprinting, may be important for specific team-sport match activities, including evading an opponent or creating a shot on goal. Maximal accelerations are energetically demanding and frequently occur from a low velocity during team-sport matches. Despite extensive research, conjecture exists regarding the thresholds by which to classify the high velocity and acceleration activity of a team-sport athlete. There is currently no consensus on the definition of a sprint or acceleration effort, even within a single sport. The aim of this narrative review was to examine the varying velocity and acceleration thresholds reported in athlete activity profiling. The purposes of this review were therefore to (1 identify the various thresholds used to classify high-velocity or -intensity running plus accelerations; (2 examine the impact of individualized thresholds on reported team-sport activity profile; (3 evaluate the use of thresholds for court-based team-sports and; (4 discuss potential areas for future research. The presentation of velocity thresholds as a single value, with equivocal qualitative descriptors, is confusing when data lies between two thresholds. In Australian football, sprint efforts have been defined as activity >4.00 or >4.17 m·s−1. Acceleration thresholds differ across the literature, with >1.11, 2.78, 3.00, and 4.00 m·s−2 utilized across a number of sports. It is difficult to compare literature on field-based sports due to inconsistencies in velocity and

    Smokeless tobacco (snuff) is a finely ground or shredded tobacco that is sniffed through the nose or placed between the cheek and gum. Chewing tobacco is used by putting a wad of tobacco inside the cheek. Smokeless tobacco is widely used by young athletes to enhance performance because nicotine improves some aspects of physiology. However, smokeless tobacco has harmful health effects, including cardiovascular disorders, linked to nicotine physiological effects, mainly through catecholamine release. Nicotine decreases heart rate variability and the ventricular fibrillation threshold, and promotes the occurrence of various arrhythmias; it also impairs endothelial-dependent vasodilation and could therefore promote premature atherogenesis. At rest, heart rate, blood pressure, inotropism, cardiac output and myocardial oxygen consumption are increased by nicotine, leading to an imbalance between myocardial oxygen demand and supply. The same occurs at submaximal levels of exercise. These increases are accompanied by a rise in systemic resistances. At maximal exercise, heart rate, cardiac output and maximal oxygen uptake (V˙O2max) are unaffected by nicotine. Because endothelial dysfunction is promoted by nicotine, paradoxical coronary vasoconstriction may occur during exercise and recovery. Nicotine induces a decrease in muscular strength and impairs anaerobic performance. However, nicotine is used in sports as it diminishes anxiety, enhances concentration and agility, improves aerobic performance and favours weight control. Importantly, smokeless tobacco, similar to cigarette smoking, leads to nicotine dependence through dopaminergic pathways. Smokeless tobacco has harmful cardiovascular effects and is addictive: it fulfils all the criteria for inclusion in the World Anti-Doping Agency prohibited list as a doping product. Smokeless tobacco use in sporting activities must be discouraged. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available In April 2015 the 7th All-Russian Festival of Student Sport took place. It was established seven years ago by the decision of the Academician V.A. Sadovnichy, rector of Lomonosov Moscow State University. This year the sports festival has embraced more than two hundreds of higher education institutions of the Russian Federation. A variety of sporting events with the participation of undergraduate and graduate students, performances by famous athletes, delivery standards and other sport events allowed to attract both participants and spectators of all ages, professional sports facilities and the degree of preparedness. A distinctive feature of the Festival’2015 was the fact of timing the celebration of the 70th anniversary of Victory in the 1941-1945Great Patriotic War in Russia. As a result, the program of the festival in addition to traditional sports and competitive events also includes sports and patriotic elements, i.e. trips to places of military glory, lectures and discussion clubs devoted to the development of sport and athletes during the war. Another innovation this year was held in the framework of the festival of scientific-practical conference “Fundamental science – sport”. The interdisciplinary nature of the conference allowed to unite representatives of different areas of knowledge, e.g. psychologists, biologists, doctors, philosophers and educators. The wide coverage of the audience and the speakers allowed to hold the conference in the format of online video simultaneously with the Tomsk State University, St. Petersburg State University, Southern Federal University and Perm State Humanitarian Teacher-Training University. To emphasize the importance of both fundamental and practical research, the conference was divided into two parts: the plenary session which highlighted the important methodological issues of interaction between science and sport, and the youth section of the conference that included reports on the

    2017-01-01

    This book addresses the application of infrared thermography in sports, examining the main benefits of this non-invasive, non-radiating and low-cost technique. Aspects covered include the detection of injuries in sports medicine, the assessment of sports performance due to the existing link between physical fitness and thermoregulation and the analysis of heat transfer for sports garments and sports equipment. Although infrared thermography is broadly considered to be a fast and easy-to-use tool, the ability to deliver accurate and repeatable measurements is an important consideration. Furthermore, it is important to be familiar with the latest sports studies published on this technique to understand its potential and limitations. Accordingly, this book establishes a vital link between laboratory tests and the sports field. .

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    2011-11-01

    Full Text Available The goal of the study was to determine a strength profile in young female athletes practising different sports and to use allometry to evaluate muscular strength with respect to body mass. The study included 42 women who practised taekwondo (n = 10, weightlifting (n = 10, canoeing (n = 14 and speed skating (n = 8. Measurements of maximal muscle torques under static conditions in 10 groups of flexors and extensors of the elbow, shoulder, hip, knee and trunk were carried out. The MANCOVA procedure was employed to compare means between the groups. A logarithm of body mass was adopted as a covariate. Relationships between body mass and muscle torques in each muscle group were determined using a procedure of linear regression. The analysis of residuals was employed for the evaluation of maximal muscle torques. Mean values of logarithms of maximal muscle torques were significantly different for the representatives of individual sports and they depended on the logarithm of body mass. It was proposed to use a mean of residuals normalized for individual muscle groups as a synthetic strength index (mean of the strength profile. The women practising canoeing were characterized by the highest strength index. Its lowest values were obtained by weightlifting and taekwondo athletes. Differences in strength profiles in the tested athletes were attributed to the specific nature of their sports. It is suggested to use an allometric relationship scaled by body mass for strength assessment.

    Gender inequality in all areas of life remains a global problem despite efforts over the past twenty years in particular to address the situation. In physical activity and sport the inequality between women and men is particularly pronounced in almost all countries, although it differs in degree. Two of the main reasons why inequality between women and men physical activity and sport is more extreme than in many other areas of social life are the result of the close association between the attributes required for sport and those associated with traditional concepts of stereotypical, hegemonic masculinity, and a lack of understanding of the difference between sex and gender. In sport and physical activity physical differences between men and women have been confused with socially constructed differences i.e. physical differences have been confused with gender differences, and this confusion has been used to justify women's lesser and limited participation at all levels. To achieve equality between women and men in physical activity and sport it will be essential that gender is identified and understood as a socially constructed and fluid concept which is a product of the relations between women and men. The fact that women bear children or are generally less physically powerful than men is not sufficient to justify why it is not considered appropriate for women to participate in certain forms of physical activity or why their participation is less valued than the participation of men. An understanding of gender and of the construction of gender relations is an important pre-requisite to addressing the inequality between women and men in physical activity and sport and in developing policies and programs which include, and are of equal benefit to both sexes. While more research on the benefits of participation in physical activity is needed, there is currently sufficient information available to identify the health related and social value of participation to both

    We aimed to increase understanding of the link between sport specialization during childhood and adolescent physical activity (PA). The objectives were as follows: (1) describe the natural course of sport participation over 5 years among children who are early sport samplers or early sport specializers and (2) determine if a sport participation profile in childhood predicts the sport profile in adolescence. Participants ( n = 756, ages 10-11 years at study inception) reported their participation in organized and unorganized PA during in-class questionnaires administered every 4 months over 5 years. They were categorized as early sport samplers, early sport specializers, or nonparticipants in year 1 and as recreational sport participants, performance sport participants, or nonparticipants in years 2 to 5. The likelihood that a childhood sport profile would predict the adolescent profile was computed as relative risks. Polynomial logistic regression was used to identify predictors of an adolescent sport profile. Compared with early sport specialization and nonparticipation, early sport sampling in childhood was associated with a higher likelihood of recreational participation (relative risk, 95% confidence interval: 1.55, 1.18-2.03) and a lower likelihood of nonparticipation (0.69, 0.51-0.93) in adolescence. Early sport specialization was associated with a higher likelihood of performance participation (1.65, 1.19-2.28) but not of nonparticipation (1.01, 0.70-1.47) in adolescence. Nonparticipation in childhood was associated with nearly doubling the likelihood of nonparticipation in adolescence (1.88, 1.36-2.62). Sport sampling should be promoted in childhood because it may be linked to higher PA levels during adolescence. Copyright © 2017 by the American Academy of Pediatrics.

    Many coaches, parents, and children believe that the best way to develop elite athletes is for them to participate in only 1 sport from an early age and to play it year-round. However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Nonsystematic review with critical appraisal of existing literature. Clinical review. Level 4. Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

    The benefits of regular exercise, physical fitness and sports participation on cardiovascular and brain health are undeniable. Physical activity reduces the risk for cardiovascular disease, type 2 diabetes, hypertension, obesity, and stroke, and produces beneficial effects on cholesterol levels, antioxidant systems, inflammation, and vascular function. Exercise also enhances psychological health, reduces age-related loss of brain volume, improves cognition, reduces the risk of developing dementia, and impedes neurodegeneration. Nonetheless, the play of sports is associated with risks, including a risk for mild TBI (mTBI) and, rarely, catastrophic traumatic injury and death. There is also growing awareness that repetitive mTBIs, such as concussion and subconcussion, can occasionally produce persistent cognitive, behavioral, and psychiatric problems as well as lead to the development of a neurodegeneration, chronic traumatic encephalopathy (CTE). In this review, we summarize the beneficial aspects of sports participation on psychological, emotional, physical and cognitive health, and specifically analyze some of the less common adverse neuropathological outcomes, including concussion, second-impact syndrome, juvenile head trauma syndrome, catastrophic sudden death, and CTE. CTE is a latent neurodegeneration clinically associated with behavioral changes, executive dysfunction and cognitive impairments, and pathologically characterized by frontal and temporal lobe atrophy, neuronal and axonal loss, and abnormal deposits of paired helical filament (PHF)-tau and 43 kDa TAR deoxyribonucleic acid (DNA)-binding protein (TDP-43). CTE often occurs as a sole diagnosis, but may be associated with other neurodegenerative disorders, including motor neuron disease (CTE-MND). Although the incidence and prevalence of CTE are not known, CTE has been reported most frequently in American football players and boxers. Other sports associated with CTE include ice hockey, professional

    Sports medicine is a profession pertaining to primary health care of sport population (competitors, coaches, referees, participants in sports recreation). It embraces the physical and mental health protection and promotion of participants in relation to a particular sport activity and sport environment, directing athletes to a sport and adapting them to sport and the sport to them. Sports medicine takes part in selection procedure, training process planning and programming, and cares for epidemiological, hygienic, nutritional and other problems in sport. The Republic of Croatia belongs to those world states in which the field of sports medicine is regulated neither by a law or by profession. A consequence is that wide circle of physicians and paramedics work in clubs and various medical units without any legal or/and professional control not being adequately educated nor having licence for it. This review is an appeal to the Croatian Medical Chamber and the Ministry of Health to make efforts to promote the education and medical profession in sports medicine.

    Organized sport provides one option for children to be physically active. However, there is a paucity of information about the relationship between children's participation in organized sport and their diet, and specifically their sports drink consumption. Therefore, the relationship between sports participation in children and the consumption of sports drinks, sugar-sweetened beverages (SSBs) and other components of diet was examined. A cross-sectional descriptive study was conducted using baseline data from the Action Schools! BC Dissemination study cohort (n = 1421; 9.90 (0.58) y; 736 girls, 685 boys). The differences between the dietary behaviours of children participating in organized sport (sport) versus those that did not participate (non-sport) was examined. A modified Physical Activity Questionnaire for Older Children (PAQ-C) was used to measure physical activity levels and participation in organized sport. A Food Frequency Questionnaire (FFQ) and 24-hour dietary recall were used to assess eating behaviour and macronutrient intake (including protein, fat, and carbohydrate as well as sugar, fibre and total calories). Fruit, vegetable and beverage quantities were hand-tallied from the dietary recall. Fruit, vegetable and beverage frequency was assessed using the FFQ. Analysis of covariance (ANCOVA) was used to analyse differences between groups and a chi-square test of association was use to determine if participation in sport was significantly associated with the proportion of children consuming sports drinks and SSBs, and with gender. Children involved in sport had a lower body mass index (BMI) and were more physically active than children in the non-sport group (p sports drinks and no difference in consumption of sports drink between sport and non-sport participants (p > .05) was observed.

    Full Text Available Abstract Position Statement: The position of The Society regarding caffeine supplementation and sport performance is summarized by the following seven points: 1. Caffeine is effective for enhancing sport performance in trained athletes when consumed in low-to-moderate dosages (~3-6 mg/kg and overall does not result in further enhancement in performance when consumed in higher dosages (≥ 9 mg/kg. 2. Caffeine exerts a greater ergogenic effect when consumed in an anhydrous state as compared to coffee. 3. It has been shown that caffeine can enhance vigilance during bouts of extended exhaustive exercise, as well as periods of sustained sleep deprivation. 4. Caffeine is ergogenic for sustained maximal endurance exercise, and has been shown to be highly effective for time-trial performance. 5. Caffeine supplementation is beneficial for high-intensity exercise, including team sports such as soccer and rugby, both of which are categorized by intermittent activity within a period of prolonged duration. 6. The literature is equivocal when considering the effects of caffeine supplementation on strength-power performance, and additional research in this area is warranted. 7. The scientific literature does not support caffeine-induced diuresis during exercise, or any harmful change in fluid balance that would negatively affect performance.

In combat sports, some investigations have also been conducted. This article’s main objective was to review the representation of specific gene polymorphisms in combat sports athletes compared to controls. The following databases were searched: PubMed, Web of Science and SportDiscus. The terms used in this search involved combat sports (boxing, karate, judo, mixed martial arts, taekwondo and wrestling, genes, genetics and candidate genes. Articles published until November 2013 were included if combat sports athletes were considered as a single group (i.e., not mixed with athletes of other sports. Seven studies were found, with two presenting no difference between combat sports athletes and controls, two presenting higher frequencies of candidate genes related to a more endurance-related profile compared to controls, and three where a more power-related gene overrepresentation was found in comparison to controls. Taken together, the initial studies about the genetic characteristics of combat sports athletes are controversial, which is probably due to the mixed (aerobic and anaerobic characteristic and to the multifactorial performance determinants of these sports.

    Anticipation has become an increasingly important research area within sport psychology since its infancy in the late 1970s. Early work has increased our fundamental understanding of skilled anticipation in sports and how this skill is developed. With increasing theoretical and practical insights and concurrent technological advancements, researchers are now able to tackle more detailed questions with sophisticated methods. Despite this welcomed progress, some fundamental questions and challenges remain to be addressed, including the (relative) contributions of visual and motor experience to anticipation, intraindividual and interindividual variation in gaze behaviour, and the impact of non-kinematic (contextual or situational) information on performance and its interaction with advanced kinematic cues during the planning and execution of (re)actions in sport. The aim of this opinion paper is to shortly sketch the state of the art, and then to discuss recent work that has started to systematically address open challenges thereby inspiring promising future routes for research on anticipation and its application in practice.

    Participation in recreational and competitive sports at an early age has long been touted as a positive influence on growth and development, and for fostering lifelong healthy lifestyles. The benefits of an active lifestyle include not only fitness, but the promotion of a sense of inclusion and improved self-esteem. These benefits are well documented in all populations, and their importance has been summarized in the recent Healthy People 2010 guidelines. The American Academy of Pediatrics has recently produced a summary statement on the benefits of activity for disabled children. They note that children with disabilities tend to have an overall lower level of fitness and an increased level of obesity. For this population, developing a lifelong desire to be active can be a simple means for limiting illness and much of the morbidity associated with sedentary lifestyles often associated with disability. For disabled youth, participation in disabled sports programs available nationally and internationally can be an effective means to promote such precepts. The goal of this focused review is to improve the learner's knowledge of the positive impact that active lifestyles can have on overall health in the disabled youth population and, as a result, modify their practice by incorporating recreational and competitive sport activities as part of improving overall patient care.

    Bell's inequality violation (BIQV) for correlations of polarization is studied for a product state of two two-mode squeezed vacuum (TMSV) states. The violation allowed is shown to attain its maximal limit for all values of the squeezing parameter, ζ. We show via an explicit example that a state whose entanglement is not maximal allow maximal BIQV. The Wigner function of the state is non-negative and the average value of either polarization is nil

    Participation in competitive sports is popular and widely encouraged throughout the United States. Reports of infectious disease outbreaks among competitive athletes and recent publicity regarding infectious disease concerns in sports underscore the need to better characterize the occurrence of these problems. To identify reports of infectious diseases in sports, we performed a comprehensive search of the medical literature (MEDLINE) and newspaper databases in two on-line services (NEXIS and DIALOG PAPERS). Articles selected from the literature review included those describing cases or outbreaks of disease in which exposure to an infectious agent was likely to have occurred during training for competitive sports or during actual competition. Articles from the newspaper review included reports of outbreaks, exposures, or preventive measures that directly or indirectly involved teams or spectators. The literature review identified 38 reports of infectious disease outbreaks or other instances of transmission through person-to-person (24 reports), common-source (nine reports), or airborne (five reports) routes; the newspaper search identified 28 reports. Infectious agents included predominantly viruses but also a variety of fungi and gram-positive and gram-negative bacteria. Our findings indicate that strategies to prevent transmission of infectious diseases in sports must recognize risks at three levels: the individual athlete, the team, and spectators or others who may become exposed to infectious diseases as a result of sports-related activities. Team physicians and others who are responsible for the health of athletes should be especially familiar with the features of infectious diseases that occur in sports and measures for the prevention of these problems.

    With reference to the discussion about shareholder versus stakeholder maximization it is argued that the normal type of maximization is in fact stakeholder-owner maxi-mization. This means maximization of the sum of the value of the shares and stake-holder benefits belonging to the dominating...... including the shareholders of a company. Although it may be the ultimate goal for Corporate Social Responsibility to achieve this kind of maximization, broad stakeholder maximization is quite difficult to give a precise definition.

    Full Text Available Sport involvement among children and adolescents has been a central field of research in sport science since years. This paper documents the participation of 11- to 15-year-olds in sport clubs and informal sport activities in Liechtenstein and examines possible gender- and age-specific differences. The analysis is based on four cross-sectional studies from 2004 to 2015 and includes the data of 1’262 children in primary (5th grade and secondary (7th and 9th grades school. According to our findings sports and exercise are considered to be one of the main leisure-time activities for all school levels (irrespective of gender. The percentage of fully sport-abstinent adolescents by 11- and 13-year-olds is about 5 %; by 15-year-olds is around 10 %. The culmination of sports club membership (with current 84.7 % appears to be at the age of 11 (5th grade. After the switch to secondary school the sports club commitment tends to decrease, while the high attendance of the informal sport activities (>85 % shows relatively stable age development. In contrast to other child and youth studies, our data indicates a levelling tendency and dissolution of classic gender differences not only in sports club commitment but also in informal sports among girls and boys.

    Full Text Available In literature, the term adapted sport indicates sports activities, modified and adapted to persons with disabilities. In spite of their highly prominent values, combat sports are underrepresented among persons with disabilities in Serbia. The benefits of combat sports practicing are numerous, and at some international hospitals, martial sports and arts already have an important role in the treatment of traumatized and disabled persons. Currently, the programme of Paralympic Games includes only two sports, these are fencing and judo, in male and female competition. Almost certainly, karate will also be included in the programme of Paralympic Games, and there are similar ambitions in the case of taekwondo as well. In addition to these sports, some martial arts, especially aikido, thai-chi-chuan and qigong, have obtained significant representation and interest among persons with disabilities. The reasons for weaker interest in other martial sports and arts, should be sought in the fact that they are underrepresented among this population, and that these persons are not offered the possibility of organized practice of such sports. Orientation towards a combat sport brings great refreshment and powerful emotional experience to each practitioner, and this fact has special significance to persons with disabilities. In Serbia, combat sports are not widely represented among persons with disabilities, and only the wrestlers with impaired hearing have achieved significant success on the international stage. On the other hand, the popularity of combat sports among persons with disabilities in the world is significantly growing. It is necessary to take concrete steps to make it so in Serbia as well.

    Maximal symmetry is a novel tool for composite pseudo Goldstone boson Higgs models: it is a remnant of an enhanced global symmetry of the composite fermion sector involving a twisting with the Higgs field. Maximal symmetry has far-reaching consequences: it ensures that the Higgs potential is finite and fully calculable, and also minimizes the tuning. We present a detailed analysis of the maximally symmetric SO(5)/SO(4) model and comment on its observational consequences.

    This study is a contribution to the discussion about the structure of performance of sport rock climbers. Because of the complex and multifaceted nature of this sport, multivariate statistics were applied in the study. The subjects included thirty experienced sport climbers. Forty three variables were scrutinised, namely somatic characteristics, specific physical fitness, coordination abilities, aerobic and anaerobic power, technical and tactical skills, mental characteristics, as well as 2 variables describing the climber’s performance in the OS (Max OS) and RP style (Max RP). The results show that for training effectiveness of advanced climbers to be thoroughly analysed and examined, tests assessing their physical, technical and mental characteristics are necessary. The three sets of variables used in this study explained the structure of performance similarly, but not identically (in 38, 33 and 25%, respectively). They were also complementary to around 30% of the variance. The overall performance capacity of a sport rock climber (Max OS and Max RP) was also evaluated in the study. The canonical weights of the dominant first canonical root were 0.554 and 0.512 for Max OS and Max RP, respectively. Despite the differences between the two styles of climbing, seven variables – the maximal relative strength of the fingers (canonical weight = 0.490), mental endurance (one of scales : The Formal Characteristics of Behaviour–Temperament Inventory (FCB–TI; Strelau and Zawadzki, 1995)) (−0.410), climbing technique (0.370), isometric endurance of the fingers (0.340), the number of errors in the complex reaction time test (−0.319), the ape index (−0.319) and oxygen uptake during arm work at the anaerobic threshold (0.254) were found to explain 77% of performance capacity common to the two styles.

    Climbing is a popular wilderness sport among a wide variety of professional athletes and amateur enthusiasts, and many styles are performed across many environments. Potential risks confront climbers, including personal health or exacerbation of a chronic condition, in addition to climbing-specific risks or injuries. Although it is not common to perform a preparticipation evaluation (PPE) for climbing, a climber or a guide agency may request such an evaluation before participation. Formats from traditional sports PPEs can be drawn upon, but often do not directly apply. The purpose of this article was to incorporate findings from expert opinion from professional societies in wilderness medicine and in sports medicine, with findings from the literature of both climbing epidemiology and traditional sports PPEs, into a general PPE that would be sufficient for the broad sport of climbing. The emphasis is on low altitude climbing, and an overview of different climbing styles is included. Knowledge of climbing morbidity and mortality, and a standardized approach to the PPE that involves adequate history taking and counseling have the potential for achieving risk reduction and will facilitate further study on the evaluation of the efficacy of PPEs.

  2. The rodeo athlete: sport science: part I.

    2010-05-01

    Based on the tradition, history and lore of the American West, as well as the individualistic nature and lifestyle of the sport of rodeo, the rodeo athlete has achieved iconic status in sport, literature, art and entertainment. For over half a century, rodeo has become a staple of organized sport programmes in high schools, universities and international competitions. The origins of rodeo grew from ranch work dating back to the Spanish vaqueros in the 1700s. The sport was officially organized in 1929 and, by the 1930s, championships were determined and the sport of rodeo surpassed baseball and auto racing in spectator attendance. Since then, sponsorship has grown, resulting in extensive worldwide popularity through major media outlets. Despite growing popularity, few investigations exist regarding the scientific aspects of the sport. Rodeo competition is an activity that is basically intermittent in nature, with short periods of highly intense activity. When considering that experience and, thus, improvement in rodeo is achieved solely through constant and punishing practices involving actual and repetitive, human versus livestock competition, the practices closely imitate a sport-specific form of interval training. Studies, which address the anthropometric and performance characteristics of rodeo competitors, reveal that they are comparable to athletes in more traditional sports. The psychological constructs conducive to performance in rodeo have been varied and limited, with most research efforts focused on personality characteristics, sensation seeking and competitive anxiety. Nevertheless, when evaluated relative to higher levels of traditional sport performance, rodeo participants closely resemble their mainstream counterparts. Although efforts to quantify this non-traditional sport are still in the initial stages, information concerning what the optimal fitness level of rodeo athletes should be for maximal performance levels, in a basically anaerobic sport

    2014-08-01

    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.

  4. Sport-specific nutrition: practical strategies for team sports.

    Science.gov (United States)

    Holway, Francis E; Spriet, Lawrence L

    2011-01-01

    Implementation of a nutrition programme for team sports involves application of scientific research together with the social skills necessary to work with a sports medicine and coaching staff. Both field and court team sports are characterized by intermittent activity requiring a heavy reliance on dietary carbohydrate sources to maintain and replenish glycogen. Energy and substrate demands are high during pre-season training and matches, and moderate during training in the competitive season. Dietary planning must include enough carbohydrate on a moderate energy budget, while also meeting protein needs. Strength and power team sports require muscle-building programmes that must be accompanied by adequate nutrition, and simple anthropometric measurements can help the nutrition practitioner monitor and assess body composition periodically. Use of a body mass scale and a urine specific gravity refractometer can help identify athletes prone to dehydration. Sports beverages and caffeine are the most common supplements, while opinion on the practical effectiveness of creatine is divided. Late-maturing adolescent athletes become concerned about gaining size and muscle, and assessment of maturity status can be carried out with anthropometric procedures. An overriding consideration is that an individual approach is needed to meet each athlete's nutritional needs.

    In sports-related muscle injuries, the main goal of the sports medicine physician is to return the athlete to competition-balanced against the need to prevent the injury from worsening or recurring. Prognosis based on the available clinical and imaging information is crucial. Imaging is crucial to confirm and assess the extent of sports-related muscle injuries and may help to guide management, which directly affects the prognosis. This is especially important when the diagnosis or grade of injury is unclear, when recovery is taking longer than expected, and when interventional or surgical management may be necessary. Several imaging techniques are widely available, with ultrasonography and magnetic resonance imaging currently the most frequently applied in sports medicine. This state of the art review will discuss the main imaging modalities for the assessment of sports-related muscle injuries, including advanced imaging techniques, with the focus on the clinical relevance of imaging features of muscle injuries. © RSNA, 2017 Online supplemental material is available for this article.

  12. Sport as art, dance as sport

    2017-11-01

    Full Text Available A standing debate in philosophy of sport concerns whether sport can count as art in some sense. But the debate is often conducted at cross purposes. Naysayers insist that no sport is an artform while proponents insist that certain sport performances count as artworks – but these are entirely consistent claims. Both sides make unwarranted assumptions: naysayers are purists about sport and art (no transaesthetic purposes whereas proponents are tokenists about artforms. Naysayers admit that figure skating may count as art yet only in non-competitive contexts. Their burden is thus to explain why a routine (e.g., Torvill and Dean’s ‘Bolero’ may count as art in a showcase but not at the Olympics. The debate is also inevitably framed in terms of whether sport counts as art, neglecting the equally viable question of whether art in some form (e.g., competitive dance may also count as sport. I conclude in favour of an appropriately qualified sport-as-art thesis.

Statistical population of the study includes Sport Goods-Producing companies in Iran (N= 180 and 122 firms formed the study sample. For testing the hypothesis, we have used Paired Samples T-Test. The analysis of findings showed that there was a meaningful difference between using advertising and sales promotion strategies. In general, we can say, there are some limited applications of using techniques and methods of sales promotion strategies in Iranian sport industry and methods of advertising. Consequently, regarding the intense competition among companies as well as fast growth of markets and fast changes in consumer’s behavior, identifying the best methods for corresponding relationship to customer would be required.

  10. Maximizing and customer loyalty: Are maximizers less loyal?

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available Despite their efforts to choose the best of all available solutions, maximizers seem to be more inclined than satisficers to regret their choices and to experience post-decisional dissonance. Maximizers may therefore be expected to change their decisions more frequently and hence exhibit lower customer loyalty to providers of products and services compared to satisficers. Findings from the study reported here (N = 1978 support this prediction. Maximizers reported significantly higher intentions to switch to another service provider (television provider than satisficers. Maximizers' intentions to switch appear to be intensified and mediated by higher proneness to regret, increased desire to discuss relevant choices with others, higher levels of perceived knowledge of alternatives, and higher ego involvement in the end product, compared to satisficers. Opportunities for future research are suggested.

  11. Implications of maximal Jarlskog invariant and maximal CP violation

    International Nuclear Information System (INIS)

    Rodriguez-Jauregui, E.; Universidad Nacional Autonoma de Mexico

    2001-04-01

    We argue here why CP violating phase Φ in the quark mixing matrix is maximal, that is, Φ=90 . In the Standard Model CP violation is related to the Jarlskog invariant J, which can be obtained from non commuting Hermitian mass matrices. In this article we derive the conditions to have Hermitian mass matrices which give maximal Jarlskog invariant J and maximal CP violating phase Φ. We find that all squared moduli of the quark mixing elements have a singular point when the CP violation phase Φ takes the value Φ=90 . This special feature of the Jarlskog invariant J and the quark mixing matrix is a clear and precise indication that CP violating Phase Φ is maximal in order to let nature treat democratically all of the quark mixing matrix moduli.

    1984-01-01

    Of 249 patients with facial injuries admitted to the Department of Stomatology and Maxillofacial Surgery, Hôpital Bel Air, Thionville, France, between 1981 and 1982, 45 (18%) were cases of injury from sporting activities. The particular characteristics of the latter lesions were their predominance in males, their increased seasonal frequency in spring and early summer, the high incidence of damage to the nasal pyramid and maxillomalar complex, and the fact that the most implicated sport was football (71% of cases). Whereas most accidents resulted in relatively minor lesions, three cases--including two from riding--involved severe, complex injuries comparable to those seen in certain car accidents. Findings in this series confirm the natural "bumper" property of the face. Emphasis is placed on the importance of well-conducted training, and the need to eliminate consideration of sport as a means for expressing aggressiveness that is not always possible in daily life.

    The possible existence of maximal or near-maximal lepton mixing constitutes an intriguing challenge for fundamental theories of flavor. We study the phenomenological consequences of maximal and near-maximal mixing of the electron neutrino with other (x=tau and/or muon) neutrinos. We describe the deviations from maximal mixing in terms of a parameter ε(equivalent to)1-2sin 2 θ ex and quantify the present experimental status for |ε| e mixing comes from solar neutrino experiments. We find that the global analysis of solar neutrino data allows maximal mixing with confidence level better than 99% for 10 -8 eV 2 ∼ 2 ∼ -7 eV 2 . In the mass ranges Δm 2 ∼>1.5x10 -5 eV 2 and 4x10 -10 eV 2 ∼ 2 ∼ -7 eV 2 the full interval |ε| e mixing in atmospheric neutrinos, supernova neutrinos, and neutrinoless double beta decay

    Full Text Available Hong Kong is well-known for its beautiful natural harbor, vibrant nightlife, as well as tremendous entertainment and shopping opportunities. It is a paradise for outdoor activities such as golfing, hiking, fishing, and water sports. Throughout the city, there are extensive hiking trails that are over 30 miles long and navigate through beautiful scenic areas and parks. The purpose of this paper is to illustrate the sport culture of Hong Kong, including the development and administration of sports and sporting events. After a thorough review on the sports development of Hong Kong, it was found that the following three main themes would guide the direction of future sports development: (a promoting “Sports for All,” (b fostering high performance sports, and (c equipping Hong Kong to host international sports events. In this regard, the Hong Kong Government provides a wide range of sports facilities and funding to support the development of sports. In addition, sport development is also supported by the business sector in Hong Kong. Among those different departments, the Leisure and Cultural Services Department (LCSD takes an active role in promoting sports in the community and administers funding support for relevant organizations under the established sports policy. The LCSD not only develops and manages a wide range of sports and recreational facilities for use by the general public, but also supports and organizes sports and recreational programs for the community. For instance, the most exciting projects people cannot wait to see their completion are the HK$19.7 billion Kai Tak Sports Complex and the Tseung Kwan O Football Training Centre that is supported with a grant of HK$133 million from the Hong Kong Jockey Club Charities Trust.

    We study the existence of the maximal quantum Fisher information matrix in the multi-parameter quantum estimation, which bounds the ultimate precision limit. We show that when the maximal quantum Fisher information matrix exists, it can be directly obtained from the underlying dynamics. Examples are then provided to demonstrate the usefulness of the maximal quantum Fisher information matrix by deriving various trade-off relations in multi-parameter quantum estimation and obtaining the bounds for the scalings of the precision limit.

    Although growing awareness about the potential long-term deleterious effects of sport-related concussion has led to increased attention to the risks of collision sports, calls to ban these sports, such as American football, might be premature. Collision sports have a relatively high incidence of concussions, but participation in these sports also confers a host of benefits. In addition, the associated risks of participation, including concussion, have not been definitively shown to outweigh the benefits they provide, and the risk-benefit ratio might vary among individuals. The risks of concussion and repetitive concussions associated with collision sports are unknown in the general population and not well characterized even in elite athlete populations. In this article, we discuss current knowledge on sports-related concussion, its neurological consequences, and implications for regulation of the practice of collision sports.

    2011-07-01

    In most Paralympic wheelchair sports, active trunk range of movement is assessed by observing shoulder girdle excursion during active trunk movements and is a key determinant of an athlete's class. However, to date research evaluating the impact of reduced trunk range of movement on wheelchair sports performance has not been conducted. In the present study, 15 non-disabled male participants performed two 20-s sprints on a wheelchair ergometer in each of three seating positions. Positions were typical of those used to enhance sitting stability in wheelchair sport and each impacted available trunk range of movement differently: condition-90 (seated with thighs horizontal; unrestricted range of movement) condition-45 (seated with thighs in 45°), and condition-0 (seated with hips maximally flexed; minimum range of movement). In condition-90, the trunk only actively contributed to the first push; for the remainder of the sprint, the trunk was held almost isometrically at 48.2° to the horizontal (range 42.1-56.4°). Similar patterns were observed for both condition-45 and condition-0. Compared with condition-90, participants in condition-0 had reduced capacity to accelerate of statistical (P sports performance, including strapping, seating position, and impairments of trunk muscle power and coordination.

    Our objective was to detect possible differences in red blood cell (RBC) deformability of elite athletes performing different types of sports and being of different age and gender.182 athletes were included in this cross-sectional study. RBC deformability was measured using the laser-assisted optical rotational cell-analyzer. Maximal elongation index (EI  max ) and shear stress at half-maximum deformation (SS  1/2 ) were calculated. The ratio SS  1/2  /EI  max  (EI  Ratio ) was calculated with low values representing high RBC deformation. Hematocrit (Hct) and mean cellular volume (MCV) were determined in venous blood. Overall RBC deformability did not differ between male and female athletes but, when separated by age of the subjects, RBC deformability increased with age in male but not in female athletes. RBC deformability was lower in Combat sports compared other sport groups. Hct was higher in male compared to female athletes while no difference was observed for MCV. MCV and Hct increased with increasing age. A negative correlation was found between the EI  Ratio  and MCV and between EI  Ratio  and Hct. RBC deformability is influenced by age and endurance rate of the sport which suggests that the RBC system may adapt to changing conditions such as adolescence with the onset effects of sex hormones or physical exercise. © Georg Thieme Verlag KG Stuttgart · New York.

    Eye injuries sustained during sport comprise up to 20 per cent of all injuries to the eye serious enough for medical attention to be sought. The prevalence of eye injuries in sport is not easily assessed due to lack of authoritative participation rates, so most studies report total numbers in a time period. The evidence on the proportion of all ocular injuries that are from sport is reviewed. The relative frequencies in different sports are compared in a qualitative manner and the sports with greater numbers of ocular injuries are detailed. In common with occupational injuries to the eye, most sports eye injuries are considered preventable. The hierarchy of action for occupational risk is detailed and adapted to use in a sports scenario. All the available international, regional and national standards on sports eye protection are detailed and their provisions compared. The major function of the standards is to provide adequate protection against the hazard of the sport concerned. These are detailed and compared as a function of energy transfer. Eye protection must not introduce additional or secondary hazards (for instance, fracturing into sharp fragments on impact) and not introduce features that would deter the wearing of eye protection (for instance, restricting field of view to impede playing the sport). The provisions of the standards intended to limit secondary hazards are detailed and compared. The need for future work in standards writing and the activities of the International Standardization Organization in sports eye protection are detailed. © 2016 Optometry Australia.

    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.

    The relationship between sport and technology is close and can be both fruitful and destructive. Technology has a constitutive function in sport as it makes the activity possible and it can enhance performance as well as the sporting experience. The use of football boots is clearly more comfortable...... and effective than playing in bare feet in a game of football. However, sport challenges its athletes by demanding the employment of less efficient means rather than more efficient means in pursuit of sport specific goals. Therefore technology can potentially subtract from the sporting experience and even...... threaten the internal logic of sport. If as an example very efficient hail cartridges were allowed for use in double trap shooting it would reduce the skills required to excel at that discipline reducing its value for participants and spectators alike. The use of forbidden performance enhancing substances...

    New fuel quality requirements and high growth rates for petrochemicals are providing both challenges and opportunities for refineries. A key challenge in refineries today is to improve of the value of the products from the FCC unit. In particular, light FCC naphtha and LCO are prime candidates for improved utilization. Processing options have been developed focusing on new opportunities for these traditional fuel components. The Total Petrochemicals/UOP Olefin Cracking Process cracks C4-C8 olefins to produce propylene and ethylene. This process can be integrated into FCC units running at all severity levels to produce valuable light olefins while reducing the olefin content of the light FCC naphtha. Integration of the Olefin Cracking Process with an FCC unit can be accomplished to allow a range of operating modes which can accommodate changing demand for propylene, cracked naphtha and alkylate. Other processes developed by UOP allow for upgrading LCO into a range of products including petrochemical grade xylenes, benzene, high cetane diesel and low sulfur high octane gasoline. Various processing options are available which allow the products from LCO conversion to be adjusted based on the needs and opportunities of an individual refinery, as well as the external petrochemical demand cycles. This presentation will examine recent refining and petrochemical trends and highlight new process technologies that can be used to generate additional revenue from petrochemical production while addressing evolving clean fuel demands.

    There is now compelling scientific evidence that increased levels of physical activity can bring wide-ranging health benefits. These benefits can extend beyond physical health to include other positive impacts relating to mental health and personal development. The sport and recreation sector is viewed as a priority area for increasing rates of physical activity. Participation rates in organised sport have been shown to be lower in females and to decline with age, and are reduced in lower socio-economic and minority groups including people from non-English speaking and Indigenous backgrounds. It is important to determine the most effective interventions that sporting organisations can use to increase people's participation. To update a review of all controlled studies evaluating interventions implemented through sporting organisations to increase participation. We updated the original (2004) searches in May 2007. We searched: The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2 2007); MEDLINE and MEDLINE In-Process and Other Non-Indexed Citations (2004 to Week 3 April 2007); EMBASE (2004 to Week 17 2007); PsyclNFO (2004 to April Week 1 2007); CINAHL (2004 to Week 1 May 2007); SPORTDiscus (2004 to April 2007); Sociological Abstracts (2004 to 2007); Dissertation Abstracts (2004 to May 2007), and a number of freely-available online health promotion and sports-related databases. We used the internet extensively to search for studies and locate information generated by sporting bodies throughout the world. Controlled studies evaluating any intervention designed to increase active and/ or non-active participation in sport by people of all ages. Interventions could include: mass media campaigns; information or education sessions; management or organisational change strategies; policy changes, for example to improve the socio-cultural environment to encourage people of specific age, gender or ethnicity to participate; changes to

    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. Nonsystematic review. Clinical review. Level 4. 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.

    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

    Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

    2013-01-01

    Background In The Netherlands, sports medicine physicians are involved in the care of about 8% of all sports injuries that occur each year. Some patients consult a sports physician directly, without being referred by a general practitioner. This study aims to determine how many patients consult a sports physician directly, and to explore differences in the profiles of these patients compared with those who are referred. Methods This was an exploratory cross-sectional study in which all new patients presenting with an injury to a regional sports medical center during September 2010 were identified. The characteristics of patients who self-referred and those who were referred by other medical professionals were compared. Results A total of 234 patients were included (mean age 33.7 years, 59.1% male). Most of the injuries occurred during soccer and running, particularly injuries of the knee and ankle. In this cohort, 39.3% of patients consulted a sports physician directly. These patients were significantly more often involved in individual sports, consulted a sports physician relatively rapidly after the onset of injury, and had received significantly less care before this new event from medical professionals compared with patients who were referred. Conclusion In this study, 39.3% of patients with sports injuries consulted a sports physician directly without being referred by another medical professional. The profile of this group of patients differed from that of patients who were referred. The specific roles of general practitioners and sports physicians in medical sports care in The Netherlands needs to be defined further. PMID:24379706

    2010-01-01

    By separating hazing, brawling, and foul play and failing to recognise that their connection to sport binds them together into a cohesive subset of sport injury and youth violence, past research has failed to show how sports-related violence is a broad example of interpersonal violence. The acceptance of violence within the sporting culture may, in part, explain why sports-related violence has not yet been widely recognised as a public health concern. This review shows that sports-related violence, including hazing, brawling and foul play, occurs among youth athletes of all ages and in a variety of different sports. The few studies to address this issue have all acknowledged the dangers of sports-related violence; however, no incident tracking method has been developed. Future research must provide accurate national estimates of the incidence of sports-related violence among youth, identify associated risk factors, evaluate preventive interventions and identify effective methods of distributing and implementing evidence-based interventions. Monitoring the magnitude and distribution of the burden of sports-related violence and building the scientific infrastructure necessary to support the development and widespread application of effective sports-related prevention interventions are essential first steps toward a reduction in the incidence of sports-related violence.

    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.

    Ecological models have been applied to investigate multiple domains influencing physical activity behaviour, including individual, social, organisational, community, environmental and policy factors. With regard to the built environment, research to date has been limited to small geographical areas and/or small samples of participants. This study examined the geographical association between provision of sport facilities and participation in sport across an entire Australian state, using objective total enumerations of both, for a group of sports, with adjustment for the effect of socioeconomic status (SES). De-identified membership registration data were obtained from state sport governing bodies of four popular team sports. Associations between participation rate, facility provision rate and SES were investigated using correlation and regression methods. Participation rate was positively associated with provision of facilities, although this was complicated by SES and region effects. The non-metropolitan region generally had higher participation rates and better provision of facilities than the metropolitan region. Better provision of sports facilities is generally associated with increased sport participation, but SES and region are also contributing factors. Implications for public health: Community-level analysis of the population, sport participation and provision of facilities should be used to inform decisions of investments in sports facilities. © 2017 The Authors.

    To further reduce the sulfur dioxide emission of the entire refining process, two scenarios of acid gas or air preheats are investigated when either of them is used simultaneously with the third enrichment scheme. The maximum overall sulfur recovery efficiency and highest combustion chamber temperature is slightly higher for acid gas preheats but air preheat is more favorable because it is more benign. To the best of our knowledge, optimization of the entire GTU + enrichment section and SRU processes has not been addressed previously.

    Full Text Available The protection and provision of the welfare of children who are in a vulnerable condition to all kinds of risk in the modern world in every field they actively take part in is acknowledged as one of the most important social responsibilites of states in this day and age. In the fight against this problem, especially developed countries promote chi ld protection policies and implement them in every sport field children take active part in. The aim of this study is to examine in which dimensions child protection system, defined as the provision of the child’s safety in all aspects including physical, social, emotional, economic, cultural, ethnic, moral, religious and political on a legal basis and in practice, is implemented within the sport systems of England and to identify the policies of sports organizations. In the study, scanning method based o n the literature was used. Research data was obtained by examining the related sources on the subject in various international libraries, journals, books and sports organizations. According to the information obtained in the study, child protection progra ms were identified to be a legal obligation for independent sports organizations responsible for the management of the sport (such as Federations, Olympic committees, sport clubs. The fundamental purpose of child protection programs is to diminish the ris k of all kinds of (sexual, physical and emotional child abuse. Sports organization establish child protection systems within their governing structure and work in coordination with the related units of clubs, federations and central administrations. Moreo ver, by providing special trainings to administrators and coaches, the stipulation of obtaining a special document for coaches who shall work with sportsmen under the age of 18 has been laid down. Special regulations and educational programs for sport fede rations have been prepared intended for the functioning of child protection system in

    Full Text Available Sports and economy have discovered each other, hoping to serve common interests. In view of transferring in a more efficient way the information about their products or services to consumers, the business operator finances sports activities for advertising purposes. A company involved in sports sponsorship can instantly transmit the message about its products to millions of potential buyers, thus increasing the market share and hence the profit that it generates. By sponsoring sport it is meant any agreement / convention, under which one party the sponsor makes available to the beneficiary the material resources, financial and / or other benefits in exchange for its association with a sport or sportsman and especially the promise to use this association with sport or sportsman for the purpose of advertising, especially TV advertising. The growing use of athletes as spokespersons for a product is largely due to the ability of athletes to attract public attention and the credibility they enjoy.

    Full Text Available We can say that sports are continuously evolving. To improve the quality of this work, changes are being made in all of these segments: development and selection of athletes, the improvement of technology for preparation and performance tactics, training methods for relaxation. On the other hand these are followed by rule changes, modern sports facilities, as well as legal regulations. One direction in the improvement of sports results is an attempt at rational spending of existing resources for athletes, regardless of whether in team or individual sports. Nanotechnology is also contributioning toward this direction. This paper points out the appearance of nanotechnology, its essence, i.e., the way it may effect the development of sports. Of course, it also points to the potential risk of applying nanotechnology to sports.

    The lack of controlled trials in the relationship between participation in adapted sports, and quality of life (QoL) and life satisfaction in people with physical disabilities encouraged us to consider conducting this study. The aim of this study was to compare the QoL and life satisfaction scores between people with physical disabilities who participated in adapted sports and those who did not participate in any adapted sports. This cross-sectional controlled study included 60 individuals with physical disabilities (paraplegia and amputee). Participants were divided into two groups based on sports participation and non-sports participation. Group one included 30 disabled elite athletes who participated in adapted sports. The control group included 30 disabled individuals not involved in any adapted sports. We compared scores on the World Health Organization Quality-of-Life Scale (WHOQoL-BREF) and the Satisfaction With Life Scale (SWLS) between the two groups. Participation in the community and QoL was examined as a reflection of participant's priority on sports participation. We found that WHOQoL-BREF physical, psychological, and social domain scores were significantly higher in group one than in the control group (p sports had significantly higher QoL and life satisfaction scores compared to people with physical disabilities not involved in any adapted sports.

    The number of systematic reviews published in the orthopaedic literature has increased, and these reviews can help guide clinical decision making. However, the quality of these reviews can affect the reader's ability to use the data to arrive at accurate conclusions and make clinical decisions. To evaluate the methodological and reporting quality of systematic reviews and meta-analyses in the sports medicine literature to determine whether such reviews should be used to guide treatment decisions. The hypothesis was that many systematic reviews in the orthopaedic sports medicine literature may not follow the appropriate reporting guidelines or methodological criteria recommended for systematic reviews. Systematic review. All clinical sports medicine systematic reviews and meta-analyses from 2009 to 2013 published in The American Journal of Sports Medicine (AJSM), The Journal of Bone and Joint Surgery (JBJS), Arthroscopy, Sports Health, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) were reviewed and evaluated for level of evidence according to the guidelines from the Oxford Centre for Evidence-Based Medicine, for reporting quality according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and for methodological quality according to the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Analysis was performed by year and journal of publication, and the levels of evidence included in the systematic reviews were also analyzed. A total of 200 systematic reviews and meta-analyses were identified over the study period. Of these, 53% included evidence levels 4 and 5 in their analyses, with just 32% including evidence levels 1 and 2 only.

    Sports related injuries are common in children and adolescents, with a reported incidence of around one in ten children each year. Boys incur more and severer sports injuries than girls, and chance for injury is greater with contact or jumping sports. Sports injuries seen in children under 10-years of age are non-specific, including contusions, mild sprains, and extremity fractures, usually Salter fractures of the physes (growth plate) or plastic fractures. In the very young athlete, sports injury of the ligaments or muscle is rare as are spine or head injuries. With growth and adolescence, the intensity of sports involvement increases. Pre-pubertal children still have open physes that are prone to injury, both acute or due to stress from a repetitive activity. In addition to injury of the physes of the long bones, injuries to the physes of apophyses are common. Ligamentous injury is uncommon before physeal closure, but can occur. After the physes fuse, ligamentous injury is seen with patterns similar to adults. This review will include a description of sports related injuries seen in children and adolescents. We will concentrate on injuries that are specific for the growing skeleton, with a brief mention of those seen after fusion of the physes.

    Full Text Available One of the characteristics of contemporary sport is certainly a wide array of sports and sport discliplines young people can choose among. This is particularly obvious through establishment of numerous schools of sport as places where people can acquire fundamental sport knoweldge and skills. The point of selection for such an engagement is the school, or, in other words, primary school children. The development of young athletes starts at a very early stage. They are faced with high demands and exposed to training sessions of different scope and intensity. In order to direct complex processes in sport efficiently and well, various factors need to be considered that affect it to a lesser or higher degree. One of those factors is indisputably the family, i.e. the influence parents have on meeting the children’s need for physical (sport activity. In the process of children’s socialization that factor is given the greatest prominence. Therefore, parents are a crucial factor in young people’s sport engagement and, thus, cannot be taken as a constituent part of a sports organization’s surroundings, but as a partner in their development.

    Spinal injuries are very common among professional or amateur athletes. Spinal sport lesions can be classified in overuse and acute injuries. Overuse injuries can be found after years of repetitive spinal load during sport activity; however specific overuse injuries can also be found in adolescents. Acute traumas are common in contact sports. Most of the acute injuries are minor and self-healing, but severe and catastrophic events are possible. The aim of this article is to review the wide spectrum of spinal injuries related to sport activity, with special regard to imaging finding.

    Spinal injuries are very common among professional or amateur athletes. Spinal sport lesions can be classified in overuse and acute injuries. Overuse injuries can be found after years of repetitive spinal load during sport activity; however specific overuse injuries can also be found in adolescents. Acute traumas are common in contact sports. Most of the acute injuries are minor and self-healing, but severe and catastrophic events are possible. The aim of this article is to review the wide spectrum of spinal injuries related to sport activity, with special regard to imaging finding

    Full Text Available Asthma is one of the chronic diseases which have are widely seen among the children. The disease has recently been in the increase all over the world and affects many children. In a study conducted with International Study of Asthma and Allergies in Childhood (ISAAC method, it was found out that prevalence of childhood asthma was 17.1%. Participation in sportive activities by the children with asthma, which is today considered as a part of asthma treatment program, makes contributions to their physical, mental and psychological development and increases their quality of life. The most recommended sports for the children with asthma are swimming and water sports. Sports like tennis and volleyball are too advised. Choice of sports depends on severity of asthma, child and #8217;s choice and whether or not asthma is kept under control. Nursing approaches for the children with asthma include correction of symptoms, training of children and their families, assistance with disease adaptation, continuing asthma care at home and interventions to make children lead healthy activities of daily life of children. With protective measures to be taken by families and children; children should be encourage for sportive activities. [TAF Prev Med Bull 2014; 13(3.000: 241-244

  10. Pediatric Issues in Sports Concussions

    Giza, Christopher C.

    2014-01-01

    Purpose of Review: Sports-related concussions are receiving increasing attention in both the lay press and medical literature. While most media attention has been on high-profile collegiate or professional athletes, the vast majority of individuals participating in contact and collision sports are adolescents and children. This review provides a practical approach toward youth sports-related concussion with a foundation in the recent guidelines, but including specific considerations when applying these management principles to children and adolescents. Recent Findings: Objective measurement of early signs and symptoms is challenging in younger patients, and many commonly used assessment tools await rigorous validation for younger patients. Excellent evidence-based guidelines exist for CT evaluation of mild traumatic brain injury presenting to the emergency department. Evidence suggests that recovery from sports-related concussion takes longer in high school athletes compared with collegiate or professionals; however, rigorous studies below high school age are still lacking. Summary: Proper care for concussion in youth requires a delicate balance of clinical skills, age-appropriate assessment, and individualized management to achieve optimal outcomes. PMID:25470161

  11. Strength in power sports: the latest scientific results

    MÁRIO C. MARQUES

    2011-06-01

    Full Text Available Problem Statement: During the last decades, strength and power training has been a major issue for, coaches,athletes and researchers. Unfortunately, despite the increasing professionalization of coaches and athletes, thereis little research data concerning performance in elite athletes. Several studies showed that a specific strengthtraining program can improve athletes’ maximal force and power production, reduce the incidence of injury, andcontribute to faster injury recovery times, thereby minimizing the number of missed practice sessions andcompetitions. To our best knowledge, however, there is no apparent consensus on the appropriate method ofstrength and muscular power training to enhance performance, especially in typically power sports. On this,some questions remain unresolved and there have focused objective of our study: How much strength does anathlete need? Is the maximum strength the key for success? Is the muscular power the main issue?Approach: Therefore, the aim of this study focuses on a literature scientific search extended about strength inpower sports specifically.Results: Studies in this area continue to contradict because they differ markedly in terms of design factors,including mode, frequency, intensity, frequency of training, and training history of subjects.Conclusions/Recommendations: We can conclude that once a given level of strength training intensity hasbeen reached in trained athletes, the appropriate physiological adaptations may well be optimized and thattraining beyond this limit provides no further benefits

    Kay, Melissa C; Kucera, Kristen L

    2018-07-01

    Mixed methods research is a relatively new approach in the field of sports medicine, where the benefits of qualitative and quantitative research are combined while offsetting the other's flaws. Despite its known and successful use in other populations, it has been used minimally in sports medicine, including studies of the clinician perspective, concussion, and patient outcomes. Therefore, there is a need for this approach to be applied in other topic areas not easily addressed by one type of research approach in isolation, such as the retirement from sport, effects of and return from injury, and catastrophic injury.

  13. Nutrition in sports

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Nutrition is one of the fundamental factors that influence the effectiveness of physical activity, increase efficiency and replenishment of muscle mass, balances the ratio of energy consumed and restored. The diet of an athlete can and should be built on common foods available and prepared in accordance with generally accepted principles of healthy eating. The need for major macronutrients and micronutrients is determined by the need for energy, the intensity of sweating and the goals for building muscle mass. Depending on the intensity of the proposed load including competition, there are individual nutritional needs and, if necessary, various food supplements may be used. The basic principles of sport nutrition are described in this article

    Conclusion: These findings indicate that the mode of sport training, which results in either high cardiovascular or high motor fitness, bears no relationship to measures of general cognition in elite athletes. The present findings suggest that coaches and athletic trainers should be encouraged to monitor athletes' stress levels during training in order to maximize the beneficial effects of such training on general cognitive performance.

    Sgrò, P; Di Luigi, L

    2017-09-01

    The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

  3. Bioethics, sport and the genetically enhanced athlete.

    Science.gov (United States)

    Miah, Andy

    2002-01-01

    This paper begins by acknowledging the interest taken by various international organisations in genetic enhancement and sport, including the US President's Council on Bioethics (July, 2002) and the World Anti-Doping Agency (March, 2002). It is noticed how sporting organisations have been particularly concerned to emphasize the 'threat' of genetics to sport, whereas other institutions have recognised the broader bioethical issues arising from this prospect, which do not readily reject the use of genetic technology in sport. Sports are identified as necessarily 'human' and 'moral' practices, the exploration of which can reveal greater insight into the intuitive fears about genetic modification. It is argued that anti-doping testing measures and sanctions unacceptably persecute the athlete. While there are substantial reasons to be concerned about the use of genetic modification in sport, the desire for policy ought not diminish the need for ethical research; nor ought such research embody the similar guise of traditional 'anti' doping strategies. Rather, the approach to genetics in sport must be informed more by broader social policies in bioethics and recognition of the greater goods arising from genetic technology.

    OBJECT There is currently no consensus on the safety of sports participation for patients with Chiari I malformation (CM-I). The authors' goal was to define the risk of sports participation for children with the imaging finding of CM-I. METHODS A prospective survey was administered to 503 CM-I patients at 2 sites over a 46-month period. Data were gathered on imaging characteristics, treatment, sports participation, and any sport-related injuries. Additionally, 81 patients completed at least 1 subsequent survey following their initial entry into the registry and were included in a prospective group, with a mean prospective follow-up period of 11 months. RESULTS Of the 503 CM-I patients, 328 participated in sports for a cumulative duration of 4641 seasons; 205 of these patients participated in contact sports. There were no serious or catastrophic neurological injuries. One patient had temporary extremity paresthesias that resolved within hours, and this was not definitely considered to be related to the CM-I. In the prospective cohort, there were no permanent neurological injuries. CONCLUSIONS No permanent or catastrophic neurological injuries were observed in CM-I patients participating in athletic activities. The authors believe that the risk of such injuries is low and that, in most cases, sports participation by children with CM-I is safe.

  6. PROMOTION OF MONTENEGRO THROUGH SPORTS

    2011-03-01

    Full Text Available Modern social structures of Montenegro exist in a hypercomplex and very dynamic environment. The complexity and dynamism are, in part, a consequence of the general characteristics of the modern age, and in part, of the transition processes which have affected the Montenegrin society. The transition processes are taking place at all levels and subsystems of the community, and its sociological milieu is facing inevitability of adaptation and immersion in such processes and trends. There is no more positive promotion for a country than a sports promotion. There is no expert team, public relations agency or a lawyer than can win Montenegro a front page. We can talk about the importance of sports for the promotion of Montenegro from another point of view. If we compare the number of occurrences of names of the selected Montenegrin athletes with that of politicians, scientists or artists in different internet search engines, we will realize how great is the capacity of marketing potential that lies in Montenegrin sports and top athletes as representatives of the products and services with the label - Made in Montenegro. In addition to the success of the Montenegrin athletes globally, the promotion of Montenegro through sports is directly contributed by the major sporting events and contests, on account of which Montenegro presented itself not only as an excellent host and organizer, but also demonstrated the remarkable state and marketing capabilities and competencies. Reputation (image is not achieved overnight. Its semiological and symbolic charge includes all (visual, vocal, environmental, personal, active inputs, which need to be channelled and created. Indeed, continual work in creating and maintaining the image of Montenegro is a public relations function. With efficiently and professionally developed media and PR strategy, the modern state of Montenegro may expect to favourably position its image at the international scene, and to present its

  7. Motor memory in sports success

    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

    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.

Additionally, in case of parachutists, sport experience of study participants were scrutinised with regard to its possible impact on the level of sensation seeking.The research involved 217 males aged 17 to 45, practising recreational high risk sports, namely: parachuting (n=98; wakeboarding (n=30; snowboarding (n=30; scuba diving (n=22; alpinism (n=20; paragliding (n=17. The control group included 54 men not involved in sports. Polish version of Sensation Seeking Scale (SSS-IV of Zuckerman was applied.Results show, that high risk sports males are featured by stronger need of sensations in comparison to control group and this concerned all but one aspect of sensation seeking variable. The only exception was the need of intellectual stimulation. Except from the thrill and adventure seeking dimension, type of sport may also be an important determinant of sensation seeking. Men practising snowboard and wakeboard presented stronger need for sensations, especially in the dimension of experience seeking, disinhibition and boredom susceptibility. Sport experience (number of jumps in parachuting did not differentiate the level of sensation seeking among investigated parachutists. Population of sport high risk male takers was not homogeneous, and therefore in future research one should analyse specific sports (or events in a certain sport separately.

  3. Criminal aspect of injuries in sports

    2016-01-01

    Full Text Available In this paper the concept of sports ethics is defined and attention is directed to kinds of behavior which are not considered as fair play, the general conception of criminal offence as well as the elements of general idea of criminal act, unlawfulness and guilt with special attention paid to the basis on which unlawfulness and delict, and with them, the criminal offence itself are excluded. Consent of the injured party as basis for excluding unlawfulness has been carefully considered, with emphasis on the fact that with accepting to participate is a certain sport an athlete does not consent to be hurt outside the frame which rules of a particular sport imply. The attitude is accepted that with his consent an athlete consented to the possibility for his integrity be endangered, which still does not mean that he consented to be injured indeed, i.e. a difference is recognized between the consequence of endangering and the consequence of injuring protected assets. After that, rules which are applied in certain sports are explained and connected with the acceptance of the injured party, and the stand is taken that acceptance of the injured party excludes existence of criminal deed only in a situation when an injury occurred within the rules of a particular sport. If the injury occurred by breaking the rules of the sport, it would be considered as a criminal act. In conclusion, the stand is taken that it is necessary to fight against all harmful occurrences in sports, including the injuries which occurred due to severe violation of rules which should be applied in a particular sport. It is concluded that consent of the injured party must not be an excuse for not applying criminal justice, if the injury occurred by violation of the rules of a particular sport.

    Many studies have confirmed the importance of market segmentation both theoretically and empirically. Surprisingly though, no study has so far addressed the issue from the perspective of leisure constraints. Since different consumers face different barriers, we look at participation in leisure activities as an outcome of the negotiation process that winter sports resort tourists go through, to balance between related motives and constraints. This empirical study reports the findings on the applicability of constraining factors in segmenting the tourists who visit winter sports resorts. Utilizing data from 1,391 tourists of winter sports resorts in Greece, five segments were formed based on their constraint, demographic, and behavioral profile. Our findings indicate that such segmentation sheds light on factors that could potentially limit the full utilization of the market. To maximize utilization, we suggest customizing marketing to the profile of each distinct winter sports resort tourist segment that emerged.

To maximize utilization, we suggest customizing marketing to the profile of each distinct winter sports resort tourist segment that emerged. PMID:29708114

    The evaluation of psychological skills by athletes and their relationship with sports performance and satisfaction has been of great interest in recent decades. Likewise, there has been an emergent tendency to focus on developing specific psychological skills for each sport. The principal aim of this study was to determine the frequency with which athletes deploy psychological skills whilst competing and whether their frequency varies in accordance with the technical, tactical and physical characteristics of the sport in question. A further objective was to establish the connection between the frequency of use of psychological skills and athletes' degree of satisfaction with their performance. The study comprised 1003 athletes practising 43 different sports, grouped into 7 categories based on the similarities between them. Frequency of use of the psychological skills was measured with the Test of Performance Strategies 3. The data analyses allowed the following conclusions to be drawn: the degree to which psychological skills are used is dependent on the technical, tactical and physical characteristics of each sport; and the higher the frequency of the use of psychological skills, the greater the athletes' degree of satisfaction with their performance. These results allow athletes and coaches to increase levels of sports performance by working on the use of psychological skills, adapted to the technical, tactical or physical requirements of the category in which their sport is included. In addition, working on different psychological skills will improve their satisfaction with sports performance.

    Full Text Available This investigation was aimed at gaining relevant knowledge about the attitudes of Podgorica consumers toward advertising through sport among. The sample included 330 students from Faculty of Economics in Podgorica, divided into six subsample groups: consumers, who do not watch sports events at all, then consumers who watch sports events 1-30 minutes, next 31-60 minutes, 61-90 minutes, 91-120 minutes, as well as consumers who watch sports events more than 120 minutes during the typical day. The sample of variables contained the system of three general attitudes which were modelled by seven-point Likert scale. The results of the measuring were analyzed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Based on the statistical analyses it was found that significant differences occur at multivariate level, as well as between all three variables at a significance level of p=.00. Hence, it is interesting to highlight that it was found there are significant differences showed up between the attitudes of consumers toward advertising through sport among the frequency of watching sports events. The significant differences were found in two of three variables, while the consumers who do not watch sports events had much more negative attitudes toward advertising though sport.

    In this historical review covering the past 25 years, we reflect on the content of manuscripts relevant to the Sport Performance section of the Journal of Sports Sciences. Due to the wide diversity of sport performance research, the remit of the Sport Performance section has been broad and includes mathematical and statistical evaluation of competitive sports performances, match- and notation-analysis, talent identification, training and selection or team organization. In addition, due to the academic interests of its section editors, they adopted a quality-assurance role for the Sport Performance section, invariably communicated through key editorials that subsequently shaped the editorial policy of the Journal. Key high-impact manuscripts are discussed, providing readers with some insight into what might lead an article to become a citation "classic". Finally, landmark articles in the areas of "science and football" and "notation analysis" are highlighted, providing further insight into how such articles have contributed to the development of sport performance research in general and the Journal of Sports Sciences in particular.

    People with epilepsy (PWEs) are often advised against participating in sports and exercise, mostly because of fear, overprotection, and ignorance about the specific benefits and risks associated with such activities. Available evidence suggests that physical exercise and active participation in sports may favorably affect seizure control, in addition to producing broader health and psychosocial benefits. This consensus paper prepared by the International League Against Epilepsy (ILAE) Task Force on Sports and Epilepsy offers general guidance concerning participation of PWEs in sport activities, and provides suggestions on the issuance of medical fitness certificates related to involvement in different sports. Sports are divided into three categories based on potential risk of injury or death should a seizure occur: group 1, sports with no significant additional risk; group 2, sports with moderate risk to PWEs, but no risk to bystanders; and group 3, sports with major risk. Factors to be considered when advising whether a PWE can participate in specific activities include the type of sport, the probability of a seizure occurring, the type and severity of the seizures, seizure precipitating factors, the usual timing of seizure occurrence, and the person's attitude in accepting some level of risk. The Task Force on Sports and Epilepsy considers this document as a work in progress to be updated as additional data become available.

    Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown. College athletes will display increased rates of specialization as they progress through their high school careers. Descriptive epidemiological study. Level 4. Three hundred forty-three athletes (115 female) representing 9 sports from a Midwest Division I University completed a previously utilized sport specialization questionnaire regarding sport participation patterns for each grade of high school. McNemar and chi-square tests were used to investigate associations of grade, sport, and sex with prevalence of sport specialization category (low, moderate, high) (a priori P ≤ 0.05). Specialization increased throughout high school, with 16.9% (n = 58) and 41.1% (n = 141) of athletes highly specialized in 9th and 12th grades, respectively. Football athletes were less likely to be highly specialized than nonfootball athletes for each year of high school ( P 0.23). The majority of Division I athletes were not classified as highly specialized throughout high school, but the prevalence of high specialization increased as athletes progressed through high school. Nonfootball athletes were more likely to be highly specialized than football athletes at each grade level. Most athletes who are recruited to participate in collegiate athletics will eventually specialize in their sport, but it does not appear that early specialization is necessary to become a Division I athlete. Athletes should be counseled regarding safe participation in sport during high school to minimize injury and maximize performance.

  14. Do current sports brassiere designs impede respiratory function?

    2005-09-01

    Although sports brassieres are more effective in limiting breast motion and related breast pain when compared with standard fashion brassieres, some females do not wear sports brassieres during physical activity, as they perceive them to be too tight around the torso, possibly impeding their performance during physical activity. The purpose of this study was to determine whether breast hypertrophy, breast momentum, and/or wearing a sports brassiere impeded respiratory function at rest and during physical activity. Twenty-two active women completed standard resting spirometry maneuvers while not wearing a brassiere. All subjects then completed maximal cycle ergometer testing in two breast support conditions (sports brassiere and no brassiere (NB)), followed by submaximal treadmill exercise tests under three breast support conditions (sports brassiere, no brassiere and fashion brassiere) while standard spirometry, brassiere pressure and comfort were measured. The sports brassiere imparted significantly more pressure on smaller breasted females' torsos when compared with the fashion brassiere (0.861 +/- 0.247 and 0.672 +/- 0.254 N.cm(-2), respectively), although this increased pressure did not appear to significantly affect measured lung volumes or brassiere comfort scores. Brassiere size affected maximal exercise ability (relative VO(2peak): smaller breasted NB: 49.84 +/- 6.15 mL.kg(-1).min(-1); larger breasted NB: 40.76 +/- 4.47 mL.kg(-1).min(-1)) as well as some temporal measures of resting and submaximal respiration. However, no significant difference was found between the no brassiere and brassiere conditions in regards to measured lung volumes. As no significant restriction to exercise performance or respiratory mechanics was found when subjects wore sports brassieres, it was concluded that active females should wear a sports brassiere during physical activity to reduce breast motion and related breast pain.

  15. IMNN: Information Maximizing Neural Networks

    2018-04-01

    This software trains artificial neural networks to find non-linear functionals of data that maximize Fisher information: information maximizing neural networks (IMNNs). As compressing large data sets vastly simplifies both frequentist and Bayesian inference, important information may be inadvertently missed. Likelihood-free inference based on automatically derived IMNN summaries produces summaries that are good approximations to sufficient statistics. IMNNs are robustly capable of automatically finding optimal, non-linear summaries of the data even in cases where linear compression fails: inferring the variance of Gaussian signal in the presence of noise, inferring cosmological parameters from mock simulations of the Lyman-α forest in quasar spectra, and inferring frequency-domain parameters from LISA-like detections of gravitational waveforms. In this final case, the IMNN summary outperforms linear data compression by avoiding the introduction of spurious likelihood maxima.

  16. Is the β phase maximal?

    International Nuclear Information System (INIS)

    2005-01-01

    The current experimental determination of the absolute values of the CKM elements indicates that 2 vertical bar V ub /V cb V us vertical bar =(1-z), with z given by z=0.19+/-0.14. This fact implies that irrespective of the form of the quark Yukawa matrices, the measured value of the SM CP phase β is approximately the maximum allowed by the measured absolute values of the CKM elements. This is β=(π/6-z/3) for γ=(π/3+z/3), which implies α=π/2. Alternatively, assuming that β is exactly maximal and using the experimental measurement sin(2β)=0.726+/-0.037, the phase γ is predicted to be γ=(π/2-β)=66.3 o +/-1.7 o . The maximality of β, if confirmed by near-future experiments, may give us some clues as to the origin of CP violation

    The report of the National Academy of Medicine named "Sport and Health" underlines the medical, social and educational dimensions of sporting activities. Various kinds of sporting practices are described: they concern the approximately 7,000 high level athletes, around 8,000 professional (licensed) sportsmen, and sporting club members (approximately 15 millions people). A large number of amateurs do not practice in any structure and therefore are neither managed in their activities nor medically followed. Some characteristics of sporting practice at various stages of life have been documented. Around 50% of the teenagers from 12 to 17 years have a sporting practice out-of-school besides the weekly three hours applied at school or college; however, the withdrawal of sporting practice by a high number of teenagers results in a sedentary lifestyle with overweight and obesity, major risks factors for health. Elderly people take a profit from a regular and medically controlled physical activity. Functional capacities are thus improved, cardiovascular risks factors among other, which results in better quality of life of the aged and delays their dependence. The benefit upon public health of sporting practice has been pointed out in the primary prevention of cardiovascular and respiratory diseases, osteoporosis, obesity, diabetes, breast and colon cancer, and mood disturbances. It is currently well acknowledged that sporting practice is an important component of public health in both primary and secondary prevention of many diseases.

    Elite athletes require the most advanced sports equipment to maintain their competitive edge, but manufacturers cannot always satisfy these athletes' specific equipment needs. Sport involvement can influence sports-equipment selections and is described as the process by which individuals rely on attitudes and belief systems to make sports-related consumption decisions. This study involved semistructured interviews with 5 elite Parasport athletes to identify and analyze the role of sport involvement in their selection of sports equipment. The results revealed that the athletes identified product limitations, created a collaborative environment, and promoted a culture of innovation to develop new sports products and address existing limitations. Theoretical and practical implications are discussed.

  6. Circadian variation in sports performance.

    Atkinson, G; Reilly, T

    1996-04-01

    Chronobiology is the science concerned with investigations of time-dependent changes in physiological variables. Circadian rhythms refer to variations that recur every 24 hours. Many physiological circadian rhythms at rest are endogenously controlled, and persist when an individual is isolated from environmental fluctuations. Unlike physiological variables, human performance cannot be monitored continuously in order to describe circadian rhythmicity. Experimental studies of the effect of circadian rhythms on performance need to be carefully designed in order to control for serial fatigue effects and to minimise disturbances in sleep. The detection of rhythmicity in performance variables is also highly influenced by the degree of test-retest repeatability of the measuring equipment. The majority of components of sports performance, e.g. flexibility, muscle strength, short term high power output, vary with time of day in a sinusoidal manner and peak in the early evening close to the daily maximum in body temperature. Psychological tests of short term memory, heart rate-based tests of physical fitness, and prolonged submaximal exercise performance carried out in hot conditions show peak times in the morning. Heart rate-based tests of work capacity appear to peak in the morning because the heart rate responses to exercise are minimal at this time of day. Post-lunch declines are evident with performance variables such as muscle strength, especially if measured frequently enough and sequentially within a 24-hour period to cause fatigue in individuals. More research work is needed to ascertain whether performance in tasks demanding fine motor control varies with time of day. Metabolic and respiratory rhythms are flattened when exercise becomes strenuous whilst the body temperature rhythm persists during maximal exercise. Higher work-rates are selected spontaneously in the early evening. At present, it is not known whether time of day influences the responses of a set

    2012-12-01

    This paper provides an overview of the ethical issues pertaining to the use of genetic insights and techniques in sport. Initially, it considers a range of scientific findings that have stimulated debate about the ethical issues associated with genetics applied to sport. It also outlines some of the early policy responses to these discoveries from world leading sports organizations, along with knowledge about actual use of gene technologies in sport. Subsequently, it considers the challenges with distinguishing between therapeutic use and human enhancement within genetic science, which is a particularly important issue for the world of sport. Next, particular attention is given to the use of genetic information, which raises questions about the legitimacy and reliability of genetic tests, along with the potential public value of having DNA databanks to economize in health care. Finally, the ethics of gene transfer are considered, inviting questions into the values of sport and humanity. It argues that, while gene modification may seem conceptually similar to other forms of doping, the requirements upon athletes are such that new forms of enhancement become increasingly necessary to discover. Insofar as genetic science is able to create safer, more effective techniques of human modification, then it may be an appealing route through which to modify athletes to safeguard the future of elite sports as enterprises of human excellence.

    Full Text Available This study aims to identify the types of maxims flouted in the conversation in famous comedy show, Indonesia Lawak Club. Likewise, it also tries to reveal the speakers‘ intention of flouting the maxim in the conversation during the show. The writers use descriptive qualitative method in conducting this research. The data is taken from the dialogue of Indonesia Lawak club and then analyzed based on Grice‘s cooperative principles. The researchers read the dialogue‘s transcripts, identify the maxims, and interpret the data to find the speakers‘ intention for flouting the maxims in the communication. The results show that there are four types of maxims flouted in the dialogue. Those are maxim of quality (23%, maxim of quantity (11%, maxim of manner (31%, and maxim of relevance (35. Flouting the maxims in the conversations is intended to make the speakers feel uncomfortable with the conversation, show arrogances, show disagreement or agreement, and ridicule other speakers.

    Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database. All studies relevant to shoulder arthroplasty and return to sport were included. The majority of patients returned to their prior level of activity within six months following TSA, RTSA, and shoulder HA. Noncontact, low demand activities are permitted by most surgeons postoperatively and generally have higher return rates than contact sports or high-demand activities. In some series, patients reported an improvement in their ability to participate in sports following the arthroplasty procedure. The rates of return to sports following TSA (75%-100%) are slightly higher than those reported for HA (67%-76%) and RTSA (75%-85%). Patients undergoing TSA, RTSA, and shoulder HA should be counseled that there is a high probability that they will be able to return to their preoperative activity level within six months postoperatively. TSA has been associated with higher rates of return to sports than RTSA and HA, although this may reflect differences in patient population or surgical indication. PMID:27672564

    2003-09-01

    The major racket sports include badminton, squash, table tennis and tennis. The growth of sports science and the commercialization of racket sports in recent years have focused attention on improved performance and this has led to a more detailed study and understanding of all aspects of racket sports. The aim here, therefore, is to review recent developments of the application of science to racket sports. The scientific disciplines of sports physiology and nutrition, notational analysis, sports biomechanics, sports medicine, sports engineering, sports psychology and motor skills are briefly considered in turn. It is evident from these reviews that a great deal of scientific endeavour has been applied to racket sports, but this is variable across both the racket sports and the scientific disciplines. A scientific approach has helped to: implement training programmes to improve players' fitness; guide players in nutritional and psychological preparation for play; inform players of the strategy and tactics used by themselves and their opponents; provide insight into the technical performance of skills; understand the effect of equipment on play; and accelerate the recovery from racket-arm injuries. Racket sports have also posed a unique challenge to scientists and have provided vehicles for developing scientific methodology. Racket sports provide a good model for investigating the interplay between aerobic and anaerobic metabolism and the effect of nutrition, heat and fatigue on performance. They have driven the development of mathematical solutions for multi-segment interactions within the racket arm during the performance of shots, which have contributed to our understanding of the mechanisms of both performance and injury. They have provided a unique challenge to sports engineers in relation to equipment performance and interaction with the player. Racket sports have encouraged developments in notational analysis both in terms of analytical procedures and the

    Full Text Available Physical capacity of athletes is an important element of success in sports achievements. Aerobic capacity has been accepted as its major component. Maximal oxygen uptake (VO2max has been regarded by majority of authors as the best indicator of aerobic capacity of an organism, and at the same time, the best indicator of an athlete’s physical capacity. The aim of the investigation was to analyze the aerobic capacity as an indicator of physical capacity of athletes, differences in their aerobic capacity with regard to the kind of sport they are practicing, as well as the differences obtained when compared to physically inactive subjects. The investigation included the determination of absolute and relative VO2max in the total of 66 male examinees. The examinees were divided into two groups of active athletes (football players (n=22 and volleyball players (n=18 of different profiles, while the third group of non-athletes served as control group. Maximal oxygen uptake was determined by performing the Astrand 6 minute cycle test. Peak values of VO2 max were recorded in the group of football players (4,25±0,27 l/min, and they were statistically significantly higher (p<0,001 compared to other examined groups. In the group of volleyball players the oxygen uptake was 3,95±0,18 l/min, while statistically significantly lower values were reported in the group of non-athletes compared to the groups of athletes (p<0,01. A similar ratio of VO2 max values was also shown by the analysis of values expressed in relative units. Our results showed that peak values of VO2 max were obtained in football players, and that football as a sport requires higher degree of endurance compared to volleyball. Having considered the morphological and functional changes which are the consequence of the training process, it can be concluded that VO2 max values are statistically significantly higher in the groups of athletes compared to the group of non-athletes.

    2004-01-01

    Over the next twenty years, a wave of change is occurring in the space-based scientific remote sensing community. While the fundamental limits in the spatial and angular resolution achievable in spacecraft have been reached, based on today s technology, an expansive new technology base has appeared over the past decade in the area of Distributed Space Systems (DSS). A key subset of the DSS technology area is that which covers precision formation flying of space vehicles. Through precision formation flying, the baselines, previously defined by the largest monolithic structure which could fit in the largest launch vehicle fairing, are now virtually unlimited. Several missions including the Micro-Arcsecond X-ray Imaging Mission (MAXIM), and the Stellar Imager will drive the formation flying challenges to achieve unprecedented baselines for high resolution, extended-scene, interferometry in the ultraviolet and X-ray regimes. This paper focuses on establishing the feasibility for the formation control of the MAXIM mission. MAXIM formation flying requirements are on the order of microns, while Stellar Imager mission requirements are on the order of nanometers. This paper specifically addresses: (1) high-level science requirements for these missions and how they evolve into engineering requirements; and (2) the development of linearized equations of relative motion for a formation operating in an n-body gravitational field. Linearized equations of motion provide the ground work for linear formation control designs.

    2014-09-01

    Sports- and exercise-related headaches are not unusual. Despite their frequent occurrence in this context, there are little epidemiologic data concerning sports-related headache. The recent attention of concussive injuries and associated post-traumatic headache has renewed interest in the study of those headaches occurring after head trauma; however, any primary headache type can also occur in the setting of contact and/or collision sports. The nonspecific nature of headaches provides unique challenges to clinicians encountering this complaint. It is, therefore, imperative that physicians treating athletes are able to distinguish the various headache types and presentations often seen in this population.

    Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome. Copyright © 2011 Elsevier Inc. All rights reserved.

    Today, mothers-to-be with an uncomplicated pregnancy are advised to practice sports on a regular basis. If they follow this advice, they put on less weight and recover more quickly from the stresses and strains of parturition, thanks to their higher level of general fitness. In addition, practicing sports helps to prevent postural damage, back pain, varices and thrombosis. The most suitable forms of sport are those of the aerobic type, such as jogging, swimming, cycling or aerobic calisthenics. However, exercises in the fitness studio and moderate strength training are also admissible provided that consideration is given to contraindications and warning signals.

    Full Text Available A sporting spectacle is an important cultural event, essentially influencing social and individual lives. In spite of this, there does not yet exist a monograph that analyzes, describes, and explains sporting performance from the point of view of aleatorism as part of the theory of sport and physical culture. Unfortunately, no monograph has developed this issue in a multi-aspectual, holistic, culturological, and philosophical way, dealing with its axiological values (aesthetic and praxeological. This applies to the relations between this phenomenon and the mechanisms that bring about the development and growth of interest in the social dimension.

    As genomic medicine continues to advance and inform clinical care, knowledge gained is likely to influence sports medicine and training practices. Susceptibility to injury, sudden cardiac failure, and other serious conditions may one day be tackled on a subclinical level through genetic testing programs. In addition, athletes may increasingly consider using genetic testing services to maximize their performance potential. This paper assesses the role of privacy and genetic discrimination laws that would apply to athletes who engage in genetic testing and the limits of these protections.

    2017-12-01

    The study examined developmental participation patterns of international top athletes. Pairs of 83 international medallists (including 38 Olympic/World Champions) and 83 non-medallists were matched by sport, age and gender. A questionnaire recorded their volume of organised (coach-led) practice/training in their respective main sport and in other sports through childhood, adolescence and adulthood, and also involvement in non-organised (peer-led) sport activity. Analyses revealed that the medallists started practice/training in their main sport at an older age than non-medallists and accumulated slightly, but significantly less main-sport practice/training through childhood/adolescence. But they participated in more practice/training in other sports, particularly before entering their main sport. The medallists also maintained engagement in other sports over more years and specialised later than the non-medallists. Other sports engaged in were mostly unrelated to an athlete's main sport. The results were robust across different types of sports. The observations are reflected against tenets of the "deliberate practice" and "Developmental Model of Sport Participation" frameworks. Early diversified practice and learning experiences are discussed relative to the expansion of youngsters' potential for future long-term learning. In elite athletes, interaction of sport-specific practice/training with early other-sports participation mostly facilitates long-term attainment of international senior medals.

    The regular monitoring of physical fitness and sport-specific performance is important in elite sports to increase the likelihood of success in competition. This study aimed to systematically review and to critically appraise the methodological quality, validation data, and feasibility of the sport-specific performance assessment in Olympic combat sports like amateur boxing, fencing, judo, karate, taekwondo, and wrestling. A systematic search was conducted in the electronic databases PubMed, Google-Scholar, and Science-Direct up to October 2017. Studies in combat sports were included that reported validation data (e.g., reliability, validity, sensitivity) of sport-specific tests. Overall, 39 studies were eligible for inclusion in this review. The majority of studies (74%) contained sample sizes sport-specific tests (intraclass correlation coefficient [ICC] = 0.43-1.00). Content validity was addressed in all included studies, criterion validity (only the concurrent aspect of it) in approximately half of the studies with correlation coefficients ranging from r = -0.41 to 0.90. Construct validity was reported in 31% of the included studies and predictive validity in only one. Test sensitivity was addressed in 13% of the included studies. The majority of studies (64%) ignored and/or provided incomplete information on test feasibility and methodological limitations of the sport-specific test. In 28% of the included studies, insufficient information or a complete lack of information was provided in the respective field of the test application. Several methodological gaps exist in studies that used sport-specific performance tests in Olympic combat sports. Additional research should adopt more rigorous validation procedures in the application and description of sport-specific performance tests in Olympic combat sports.

    Conclusion: Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls.

    Full Text Available Sports participation is considered beneficial for the development of socially vulnerable youth, not only in terms of physical health but also in terms of cognitive, social and emotional health. Despite the strong belief that sports clubs offer a setting for positive youth development, there is limited knowledge about how socially vulnerable youths experience their participation in these clubs. Interviews were conducted with 22 socially vulnerable youths that play a sport at a local sports club. An inductive content analysis was conducted and three themes were discovered that are included in the positive and negative sports experiences: the extent to which the youths experienced visibility of their skills, the extent to which the youths felt confident while playing their sport, and the extent to which the youths felt that sport was a challenge they liked to take on. More importantly, there was a fragile balance within each of the themes and the sports coaches played an important role in installing and maintaining a supportive environment in which the youths could have meaningful, consistent and balanced sports experiences. It is not self-evident that for socially vulnerable youth sports experiences are positive and supporting.

    This article explores the arguments surrounding the use of human enhancement technologies in sport, arguing for a reconceptualization of the doping debate. First, it develops an overview and critique of the legislative structures on enhancement. Subsequently, a conceptual framework for understanding the role of technological effects in sport is advanced. Finally, two case studies (hypoxic chambers and gene transfer) receive specific attention, through which it is argued that human enhancement technologies can enrich the practice of elite sports rather than diminish them. In conclusion, it is argued that elite sports are at a pivotal moment in their history as an increasing range of enhancements makes less relevant the protection of the natural human through anti-doping.

    Full Text Available With regard to the organization of professional clubs, two models can be applied. According to the first model, clubs have the freedom to choose the organizational form (association or commercial company in which sports activities will be carried out. Second model imposes the requirement for the clubs to be organized in the form of commercial company, in one of the corporation forms, provided that it can be also specialized sports form. To the establishment and operation of sports associations, as sui generis commercial companies, apply more specific rules concerning: the conditions for the establishment of clubs; conditions for participation in professional and management bodies; prohibiting multiple ownership of sports clubs, i.e., prohibition of membership; allocation of net profit; control over the work of clubs; state aid (subsidies for the clubs.

    Full Text Available This paper presents a brief overview of a significant element of the sport marketing management model called the marketing mix. The marketing mix is crucial because it defines the sport business, and much of the sport marketer’s time is spent on various functions within the marketing mix. The marketing mix is the strategic combination of the product, price, place and promotion elements. These elements are typically called the four Ps of marketing. Decisions and strategies for each are important for the marketer. Information for making educated decisions involving the four Ps comes from the marketing research involving primarily the four Cs - consumer, competitor, company and climate. A critical decision and one of the greatest challenges for the sport business is how to strategically combine the four Ps to best satisfy the consumer, meet company objectives, enhance market position, and enhance competitive advantages.

    Full Text Available In spite of the wide range of injuries in adolescents during sports activities, there are only a few studies investigating the type and frequency of sport injuries in puberty. However, this information may help to prevent, diagnose and treat sports injuries among teens. 4468 injuries in adolescent patients were treated over a ten year period of time: 66,97% were boys and 32.88% girls. The most frequent sports injuries were football (31.13% followed by handball (8.89% and sports during school (8.77%. The lower extremity was involved in 68.71% of the cases. Knee problems were seen in 29.79% of the patients; 2.57% spine and 1.99% head injuries. Injuries consisted primarily of distortions (35.34% and ligament tears (18.76%; 9,00% of all injuries were fractures. We found more skin wounds (6:1 and fractures (7:2 in male patients compared to females. The risk of ligament tears was highest during skiing. Three of four ski injuries led to knee problems. Spine injuries were observed most often during horse riding (1:6. Head injuries were seen in bicycle accidents (1:3. Head injuries were seen in male patients much more often then in female patients (21:1. Fractures were noted during football (1:9, skiing (1:9, inline (2:3, and during school sports (1:11. Many adolescents participate in various sports. Notwithstanding the methodological problems with epidemiological data, there is no doubt about the large number of athletes sustain musculoskeletal injuries, sometimes serious. In most instances, the accident does not happened during professional sports and training. Therefore, school teachers and low league trainer play an important role preventing further accidence based on knowledge of individual risk patterns of different sports. It is imperative to provide preventive medical check-ups, to monitor the sport-specific needs for each individual sports, to observe the training skills as well as physical fitness needed and to evaluation coaches education.

  17. Bridging the semantic gap in sports

    2003-01-01

    One of the major challenges facing current media management systems and the related applications is the so-called "semantic gap" between the rich meaning that a user desires and the shallowness of the content descriptions that are automatically extracted from the media. In this paper, we address the problem of bridging this gap in the sports domain. We propose a general framework for indexing and summarizing sports broadcast programs. The framework is based on a high-level model of sports broadcast video using the concept of an event, defined according to domain-specific knowledge for different types of sports. Within this general framework, we develop automatic event detection algorithms that are based on automatic analysis of the visual and aural signals in the media. We have successfully applied the event detection algorithms to different types of sports including American football, baseball, Japanese sumo wrestling, and soccer. Event modeling and detection contribute to the reduction of the semantic gap by providing rudimentary semantic information obtained through media analysis. We further propose a novel approach, which makes use of independently generated rich textual metadata, to fill the gap completely through synchronization of the information-laden textual data with the basic event segments. An MPEG-7 compliant prototype browsing system has been implemented to demonstrate semantic retrieval and summarization of sports video.

This essay is based on the provided data from the literature related to SD, including definition, practice areas and research fields. To discuss the data, six areas were categorized: shares in sports dentistry; oral health of athlete; sports-related dental implications; dental-facial trauma; face shields; and mouthguards. The analyzed data show that the SD is still an underexplored field of action by dentists, but it is expanding, despite not being recognized specialty by the Federal Council of Dentistry, but the Brazilian Academy of Sports Dentistry has been created with a mission to show the real importance of Dentistry in sport. The dentist should be part of the group of professionals associated with the athlete to perform periodic checks in order to ensure oral health which may contribute to athletes´performance. When impact occurs, however, it would be possible reduce the severity of the impact related to injuries, by using helmets, masks, goggles, face shields and mouthguard. Additionally, it is imperative that dentists, sports coaching, athletes, and professional who work with athletes be aware of the benefits of incorporating SD as an important academic and professional subject.

In contrast, a similar right conferred by a Community trade mark, concerns the application of the mark throughout the Community. Use of the mark is in particular the placement of the sign to the goods covered by the right of protection or their packaging, delivering and placing the goods on the market, import or export, as well as offering or providing services under that mark and the use of such a sign for advertising purposes. In the era of big money that undoubtedly govern the sport today, the law of trademarks, beside the rights to broadcast sporting events, gaining for all sporting significance of key organizational units. Clubs, associations and sports federations benefit from trademark rights, principally through the granting of licenses to entrepreneurs to use them.

    The aim of the study was to answer the following questions: What factors determine that disabled people take up systematic sport activity or should make such a decision? What reasons are able to eliminate the handicapped from process of regular going in for sport? Three groups of men participated. The group of disabled sportsmen included 39 subjects, the group of non-active disabled people 36 subjects and the group of able-bodied students 45 subjects. All the involved people answered the questions of the questionnaire, which concerned factors associated with sport activity of the handicapped and their socio-demographic characteristics, among other things. The opportunity of improvement of the health status is the main advantage of the sport for disabled people (53%). The chance of self-testing and sport competition was pointed out by 47% of subjects. The most common reason for taking up sport activity was sport passion (over 50%). The others were: possibility of creating new contacts with people, improvement of the physical condition, chance of self-testing and passing free time (23%). The lack of free time was the factor eliminating from sport activity in the second group (28%). The other problem was the shortage of appropriate clubs, equipment, infrastructure etc. (almost 25%). Students concluded that sport for disabled people aims to improve the mental condition mainly (42%). Quite similar percentage of the group (38%) didn't see any reason that was able to exclude the handicapped from goingin for sport. (1) Not only does active going in for sport improve the physical condition of the handicapped but strengthen them psychically as well. (2) The lack of sport activity in disabled people is to a high degree a result of low number of sport clubs, organisations, buildings as well as presence of architectural barriers.

    To investigate the clinical characteristics of acute type A aortic dissection (ATAAD) occurring during a sporting activity. The subjects of this study were 615 patients who underwent surgery for ATAAD between 1990 and 2015. The patients were divided into two groups according to whether the ATAAD was associated with a sporting activity (sports group: n = 25, mean age 62.3 years; non-sports group: n = 590, mean age 63.7 years). Specific activity was assessed in the sports group, and the characteristics and outcomes were compared between the groups. The sports group accounted for 5% of the patients with daytime onset ATAAD (25/479). The most common sport was golf (n = 8), followed by swimming (n = 4), cycling (n = 4), and weight lifting (n = 3). The average diameter of the ascending aorta on preoperative computed tomography was 4.8 cm. The dissection characteristics of the sports group included DeBakey type I (n = 23, 92%) and malperfusion (n = 9, 36%), which were similar to those of the non-sports group. The 30-day mortality rates were 16% (4/25) for the sports group and 8% (49/590) for the non-sports group (P = 0.33). The most common sport associated with ATAAD was golf, followed by swimming cycling, and weight lifting. The findings of this study reinforce that sports-related aortic dissection is not a unique clinical condition of young syndromic patients, but can occur in all age groups.

  5. Acute Effects of Carbohydrate Supplementation on Intermittent Sports Performance.

    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

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

    The question of whether altitude training can enhance subsequent sea-level performance has been well investigated over many decades. However, research on this topic has focused on athletes from individual or endurance sports, with scant number of studies on team-sport athletes. Questions that need to be answered include whether this type of training may enhance team-sport athlete performance, when success in team-sport is often more based on technical and tactical ability rather than physical capacity per se. This review will contrast and compare athletes from two sports representative of endurance (cycling) and team-sports (soccer). Specifically, we draw on the respective competition schedules, physiological capacities, activity profiles and energetics of each sport to compare the similarities between athletes from these sports and discuss the relative merits of altitude training for these athletes. The application of conventional live-high, train-high; live-high, train-low; and intermittent hypoxic training for team-sport athletes in the context of the above will be presented. When the above points are considered, we will conclude that dependent on resources and training objectives, altitude training can be seen as an attractive proposition to enhance the physical performance of team-sport athletes without the need for an obvious increase in training load.

  9. Evaluating judge performance in sport.

    Looney, Marilyn A

    2004-01-01

    Many sports, such as, gymnastics, diving, ski jumping, and figure skating, use judges' scores to determine the winner of a competition. These judges use some type of rating scale when judging performances (e.g., figure skating: 0.0 - 6.0). Sport governing bodies have the responsibility of setting and enforcing quality control parameters for judge performance. Given the judging scandals in figure skating at the 1998 and 2002 Olympics, judge performance in sport is receiving greater scrutiny. The purpose of this article is to illustrate how results from Rasch analyses can be used to provide in-depth feedback to judges about their scoring patterns. Nine judges' scores for 20 pairs of figure skaters who competed at the 2002 Winter Olympics were analyzed using a four-faceted (skater pair ability, skating aspect difficulty, program difficulty, and judge severity) Rasch rating scale model that was not common to all judges. Fit statistics, the logical ordering of skating aspects, skating programs, and separation indices all indicated a good fit of the data to the model. The type of feedback that can be given to judges about their scoring pattern was illustrated for one judge (USA) whose performance was flagged as being unpredictable. Feedback included a detailed description of how the rating scale was used; for example, 10% of all marks given by the American judge were unexpected by the model (Z > |2|). Three figures illustrated differences between the judge's observed and expected marks arranged according to the pairs' skating order and final placement in the competition. Scores which may represent "nationalistic bias" or a skating order influence were flagged by looking at these figures. If sport governing bodies wish to improve the performance of their judges, they need to employ methods that monitor the internal consistency of each judge as a many-facet Rasch analysis does.

  10. Maximal Abelian sets of roots

    Lawther, R

    2018-01-01

    In this work the author lets \\Phi be an irreducible root system, with Coxeter group W. He considers subsets of \\Phi which are abelian, meaning that no two roots in the set have sum in \\Phi \\cup \\{ 0 \\}. He classifies all maximal abelian sets (i.e., abelian sets properly contained in no other) up to the action of W: for each W-orbit of maximal abelian sets we provide an explicit representative X, identify the (setwise) stabilizer W_X of X in W, and decompose X into W_X-orbits. Abelian sets of roots are closely related to abelian unipotent subgroups of simple algebraic groups, and thus to abelian p-subgroups of finite groups of Lie type over fields of characteristic p. Parts of the work presented here have been used to confirm the p-rank of E_8(p^n), and (somewhat unexpectedly) to obtain for the first time the 2-ranks of the Monster and Baby Monster sporadic groups, together with the double cover of the latter. Root systems of classical type are dealt with quickly here; the vast majority of the present work con...

    In this data-rich era of astronomy, there is a growing reliance on automated techniques to discover new knowledge. The role of the astronomer may change from being a discoverer to being a confirmer. But what do astronomers actually look at when they distinguish between “sources” and “noise?” What are the differences between novice and expert astronomers when it comes to visual-based discovery? Can we identify elite talent or coach astronomers to maximize their potential for discovery? By looking to the field of sports performance analysis, we consider an established, domain-wide approach, where the expertise of the viewer (i.e., a member of the coaching team) plays a crucial role in identifying and determining the subtle features of gameplay that provide a winning advantage. As an initial case study, we investigate whether the SportsCode performance analysis software can be used to understand and document how an experienced Hi astronomer makes discoveries in spectral data cubes. We find that the process of timeline-based coding can be applied to spectral cube data by mapping spectral channels to frames within a movie. SportsCode provides a range of easy to use methods for annotation, including feature-based codes and labels, text annotations associated with codes, and image-based drawing. The outputs, including instance movies that are uniquely associated with coded events, provide the basis for a training program or team-based analysis that could be used in unison with discipline specific analysis software. In this coordinated approach to visualization and analysis, SportsCode can act as a visual notebook, recording the insight and decisions in partnership with established analysis methods. Alternatively, in situ annotation and coding of features would be a valuable addition to existing and future visualization and analysis packages.

    Full Text Available The transmission of positive values between parents and children is generally considered to be the hallmark of successful socialization. As this issue has been widely discussed but surprisingly little researched - especially with reference to core sport values - in this study we aimed to: 1 analyze adolescent athletes’ acceptance of the sport values their parents want to transmit to them (i.e., parental socialization values and 2 examine the relationship between parental involvement in children’s sportive activity and adolescents’ acceptance of their parents’ socialization values. One hundred and seventy-two Italian adolescents (48.3% male, 51.7% female who regularly practice team sports were asked to fill out a questionnaire which included the Youth Sport Values Questionnaire – 2 and the Parental Involvement in Sport Questionnaire. The dyadic correlations revealed that young athletes are in general willing to accept their parents’ socialization values in regards to sport. Moreover, from the relative weight analysis (a relatively new data analysis strategy, it emerged that parental involvement characterized by praise and understanding is the most important predictor of adolescents’ willingness to accept their parents’ sport values. Implications of these results and further expansion of the study are discussed.

  16. The physiology of growth hormone and sport.

    2012-02-01

    The growth hormone (GH)\\/ insulin-like growth factor-I (IGF-I) axis exerts short-and long-term metabolic effects that are potentially important during exercise. Exercise is a potent stimulus to GH release and there is some evidence that the acute increase in GH is important in regulating substrate metabolism post-exercise. Regular exercise also increases 24-hour GH secretion rates, which potentially contributes to the physiologic changes induced by training. The effects of GH replacement in GH-deficient adults provide a useful model with which to study the effects of the more long-term effects of the GH\\/ IGF-I axis. There is convincing evidence that GH replacement increases exercise capacity. Measures of exercise performance including maximal oxygen uptake (VO2max) and ventilatory threshold (VeT) are impaired in GH deficiency and improved by GH replacement, probably through some combination of increased oxygen delivery to exercising muscle, increased fatty acid availability with glycogen sparing, increased muscle strength, improved body composition and improved thermoregulation. Administration of supraphysiologic doses of GH to athletes increases fatty acid availability and reduces oxidative protein loss particularly during exercise, and increases lean body mass. It is not known whether these effects translate to improved athletic performance, although recombinant human GH is known to be widely abused in sport. The model of acromegaly provides evidence that long-term GH excess does not result in improved performance but it is possible that a "window" exists in which the protein anabolic effects of supraphysiologic GH might be advantageous.

    Full Text Available Sport marketing involves marketing fundamentals applied in one industry, the sport business industry. The development of sport marketing fundamentals is therefore based on basic marketing principles. The practice and activities of sport marketing are also based on basic marketing activities, but are modified and adapted to the sport business industry. Therefore, sport marketing is based on its primary and parent discipline - marketing. Sport marketing is one of the most important functions of a sport business. This is because the sport marketing activities will define the business. The growth of the sport industry is phenomenal and shows no signs of slowing. Also, sport marketing is a process. A process is a continuous cycle. Therefore, marketing is a function that never ends. The sport marketing management model is an illustration of the elements and process of sport marketing. It should serve as a guide for managing the company’s marketing functions. The model illustrates the elements of marketing, the succession of elements and functions, the process of managing, and the interdependence of the elements This paper presents an overview of the model, sport marketing management, each element and the process.

    2016-01-01

    Over the past 15 years, there has been an increase in youth sports participation with a concomitant increase in early year-round training in a single sport. Many factors contribute to the desire of parents and coaches to encourage early single sport specialization, including the desire to give the young athlete an edge in competition, pursuit of scholarships, and potential professional status, and the ability to label a young athlete as elite at an early age. Despite these perceived advantages, some data suggest that early sport specialization does not lead to a competitive advantage over athletes who participate in multiple sports. Although the data are limited, there is some evidence that early sport specialization may put the young athlete at risk for overuse injuries. The focus of this review is to highlight the evidence regarding early sport specialization and risk for injury; discuss the risk factors for overuse injury in high-risk sports including ice hockey, swimming, gymnastics, and baseball; and discuss future potential research that would help define the risk of injury for young athletes who participate in early sport specialization. © 2015 The Author(s).

    One of the key components in sports injury prevention is the identification of imbalances in leg muscle strength. However, different leg muscle characteristics may occur in large playing area (field) sports and small playing area (court) sports, which should be considered in regular injury prevention assessment. This study examined the isokinetic hamstrings-to-quadriceps (H:Q) ratio and bilateral leg strength balance in 40 male college (age: 23.4 ± 2.5 yrs) team sport players (field sport = 23, soccer players; court sport = 17, volleyball and basketball players). Five repetitions of maximal knee concentric flexion and concentric extension were performed on an isokinetic dynamometer at two speeds (slow: 60°·s(-1) and fast: 300°·s(-1)) with 3 minutes rest between tests. Both legs were measured in counterbalanced order with the dominant leg being determined as the leg used to kick a ball. The highest concentric peak torque values (Nm) of the hamstrings and quadriceps of each leg were analyzed after body mass normalization (Nm·kg(-1)). Court sport players showed significantly weaker dominant leg hamstrings muscles at both contraction speeds (P Sport-specific leg muscle strength was evident in college players from field and court sports. These results suggest the need for different muscle strength training and rehabilitation protocols for college players according to the musculature requirements in their respective sports.

    Using Australian Football League (AFL) matches as a case study, we investigated the frequency, length and content of marketing strategies for sports betting during two specific settings: 1) at stadiums during four live matches; and 2) during eight televised broadcasts of matches. Census of sports betting marketing during Round 12 of the 2011 AFL premiership season. Per match, there was an average of 58.5 episodes (median 49.5, s.d 27.8) and 341.1 minutes (median 324.1 minutes and s.d 44.5) of sports betting marketing at stadiums, and 50.5 episodes (median 53.5, s.d 45.2) and 4.8 minutes (median 5.0 minutes, s.d 4.0) during televised broadcasts. A diverse range of marketing techniques were used to: a) embed sports betting within the game; b) align sports betting with fans' overall experience of the game; and c) encourage individuals to bet live during the game. There were very few visible or audible messages (such as responsible gambling or Gambler's Help messages) to counter-frame the overwhelmingly positive messages that individuals received about sports betting during the match. This study raises important questions about the impacts of saturation, integrated and impulse gambling marketing strategies in sporting matches. Future research should explore: 1) how wagering industry marketing strategies may affect the attitudes and behaviours of community sub-groups (e.g. young male sports fans, and children); and 2) which public health and policy strategies, including regulation and harm minimisation messaging, will be effective in responding to wagering industry marketing strategies during sporting matches. © 2012 The Authors.

    Weight gain has been identified as being responsible for increased morbidity and mortality rates of schizophrenia patients. For the management of weight gain, exercise is one of the most acknowledged interventions. At the same time, exercise and sports have been recognized for their positive impact on psychiatric symptoms of schizophrenia. However, the neurobiological basis for this remains poorly understood. We aimed to examine the effect of sports participation on weight gain, psychiatric symptoms and brain activation during sports observation in schizophrenia patients. Thirteen schizophrenia patients who participated in a 3-month program, including sports participation and 10 control schizophrenia patients were studied. In both groups, body mass index (BMI), Positive and Negative Syndrome Scale (PANSS), and brain activation during observation of sports-related actions measured by functional magnetic resonance imaging were accessed before and after a 3-month interval. BMI and general psychopathology scale of PANSS were significantly reduced in the program group but not in the control group after a 3-month interval. Compared with baseline, activation of the body-selective extrastriate body area (EBA) in the posterior temporal-occipital cortex during observation of sports-related actions was increased in the program group. In this group, increase in EBA activation was associated with improvement in the general psychopathology scale of PANSS. Sports participation had a positive effect not only on weight gain but also on psychiatric symptoms in schizophrenia. EBA might mediate these beneficial effects of sports participation. Our findings merit further investigation of neurobiological mechanisms underlying the therapeutic effect of sports for schizophrenia.

    We study the synchronizability of duplex networks formed by two randomly generated network layers with different patterns of interlayer node connections. According to the master stability function, we use the smallest nonzero eigenvalue and the eigenratio between the largest and the second smallest eigenvalues of supra-Laplacian matrices to characterize synchronizability on various duplexes. We find that the interlayer linking weight and linking fraction have a profound impact on synchronizability of duplex networks. The increasingly large inter-layer coupling weight is found to cause either decreasing or constant synchronizability for different classes of network dynamics. In addition, negative node degree correlation across interlayer links outperforms positive degree correlation when most interlayer links are present. The reverse is true when a few interlayer links are present. The numerical results and understanding based on these representative duplex networks are illustrative and instructive for building insights into maximizing synchronizability of more realistic multiplex networks.

    from the depths of human evolution. Conclusions: We understand current sport as a cultural phenomenon in two dimensions. The first dimension is sport from 19th to 21st century, as an integral part of universal human culture, as a general cultural artefact. In connection with the civilization, there are all compatible features of today existing civilizations showed in sport. The second dimension of viewing the sport shifts to the forefront its aesthetic aspects, its imagery and ability to experience as domains of fine arts and sports aesthetics. The problem of current relationship between civilizations and sport also includes the sports aspect of migration. Migrating athletes bring to the new homeland (and often to another civilization excellent sport values and they are largely pragmatically assimilated into the culture of a new home and are seeking a new form of identity. In a historically short period of time when this phenomenon appeared in the sports scene, it cannot be exactly confirmed that the identity of migrating athletes who left their own civilization or original national culture, is actually changing. The problem of sports migration has to be seen in terms of coexistence of civilizations along the lines of tolerance and multiculturalism today. However, on the basis of previo

    Amputation of a limb may have a negative impact on the psychological and physical well-being, mobility and social life of individuals with limb amputations. Participation in sports and/or regular physical activity has a positive effect on the above mentioned areas in able-bodied individuals. Data concerning participation in sports or regular physical activity together with its benefits and risks for individuals with limb amputations are scarce. No systematic review exists that addresses a wide range of outcomes such as biomechanics, cardiopulmonary function, psychology, sport participation and sport injuries. Therefore, the aim of this article is to systematically review the literature about individuals with limb amputations and sport participation. MEDLINE (PubMed), EMBASE, CINAHL® and SportDiscus® were searched without time or language restrictions using free text words and MeSH terms. The last search date was 31 March 2010. Books, internet sites and references of included papers were checked for papers relevant to the topic under review. Papers were included if the research topic concerned sports and a minimum of ten individuals with limb amputations were part of the study population. Papers were excluded if they included individuals with amputations of body parts other than upper or lower limbs or more distal than the wrist or ankle, or if they consisted of case reports, narrative reviews, books, notes or letters to the editor. Title, abstract and full-text assessments were performed by two independent observers following a list of preset criteria. Of the 3689 papers originally identified, 47 were included in the review.

    Full Text Available Maxim is a principle that must be obeyed by all participants textually and interpersonally in order to have a smooth communication process. Conversation maxim is divided into four namely maxim of quality, maxim of quantity, maxim of relevance, and maxim of manner of speaking. Violation of the maxim may occur in a conversation in which the information the speaker has is not delivered well to his speaking partner. Violation of the maxim in a conversation will result in an awkward impression. The example of violation is the given information that is redundant, untrue, irrelevant, or convoluted. Advertisers often deliberately violate the maxim to create unique and controversial advertisements. This study aims to examine the violation of maxims in conversations of TV ads. The source of data in this research is food advertisements aired on TV media. Documentation and observation methods are applied to obtain qualitative data. The theory used in this study is a maxim theory proposed by Grice (1975. The results of the data analysis are presented with informal method. The results of this study show an interesting fact that the violation of maxim in a conversation found in the advertisement exactly makes the advertisements very attractive and have a high value.

  11. LOAD THAT MAXIMIZES POWER OUTPUT IN COUNTERMOVEMENT JUMP

    Full Text Available ABSTRACT Introduction: One of the main problems faced by strength and conditioning coaches is the issue of how to objectively quantify and monitor the actual training load undertaken by athletes in order to maximize performance. It is well known that performance of explosive sports activities is largely determined by mechanical power. Objective: This study analysed the height at which maximal power output is generated and the corresponding load with which is achieved in a group of male-trained track and field athletes in the test of countermovement jump (CMJ with extra loads (CMJEL. Methods: Fifty national level male athletes in sprinting and jumping performed a CMJ test with increasing loads up to a height of 16 cm. The relative load that maximized the mechanical power output (Pmax was determined using a force platform and lineal encoder synchronization and estimating the power by peak power, average power and flight time in CMJ. Results: The load at which the power output no longer existed was at a height of 19.9 ± 2.35, referring to a 99.1 ± 1% of the maximum power output. The load that maximizes power output in all cases has been the load with which an athlete jump a height of approximately 20 cm. Conclusion: These results highlight the importance of considering the height achieved in CMJ with extra load instead of power because maximum power is always attained with the same height. We advise for the preferential use of the height achieved in CMJEL test, since it seems to be a valid indicative of an individual's actual neuromuscular potential providing a valid information for coaches and trainers when assessing the performance status of our athletes and to quantify and monitor training loads, measuring only the height of the jump in the exercise of CMJEL.

    The relationship between recovery and fatigue and its impact on performance has attracted the interest of sport science for many years. An adequate balance between stress (training and competition load, other life demands) and recovery is essential for athletes to achieve continuous high-level performance. Research has focused on the examination of physiological and psychological recovery strategies to compensate external and internal training and competition loads. A systematic monitoring of recovery and the subsequent implementation of recovery routines aims at maximizing performance and preventing negative developments such as underrecovery, nonfunctional overreaching, the overtraining syndrome, injuries, or illnesses. Due to the inter- and intraindividual variability of responses to training, competition, and recovery strategies, a diverse set of expertise is required to address the multifaceted phenomena of recovery, performance, and their interactions to transfer knowledge from sport science to sport practice. For this purpose, a symposium on Recovery and Performance was organized at the Technical University Munich Science and Study Center Raitenhaslach (Germany) in September 2016. Various international experts from many disciplines and research areas gathered to discuss and share their knowledge of recovery for performance enhancement in a variety of settings. The results of this meeting are outlined in this consensus statement that provides central definitions, theoretical frameworks, and practical implications as a synopsis of the current knowledge of recovery and performance. While our understanding of the complex relationship between recovery and performance has significantly increased through research, some important issues for future investigations are also elaborated.

How does sportinfluence social and cultural evolutions? What are the cultural tendencies which can be distinguished in the sports practice?These are a few questions which could lead to establishing raports between sports, culture and society. Sport is more andmore amrked by the charactersitics of postmoderinsm. New social values are being vehiclated by current generations whichinfluence sportive behaviours. The popularity of sports has a big influence in the process of globalisation of politics,economics and culture. In our days we observe the fact that some contradictions are being manifested: globalisation andindividualisation, „sportivisation” and „desportivisation”, a culture of health and a culture of amusement and finally,spontaneity and fragmentation compared to the security and autentification of the individual.

  15. Cannabis in Sport

    2013-01-01

    Since 2004, when the World Anti-Doping Agency assumed the responsi-bility for establishing and maintaining the list of prohibited substances and methods in sport (i.e. the Prohibited List), cannabinoids have been prohibited in all sports during competition. The basis for this prohibition can be found in the World Anti-Doping Code, which defines the three criteria used to consider banning a substance. In this context, we discuss the potential of can-nabis to enhance sports performance, the risk it poses to the athlete’s health and its violation of the spirit of sport. Although these compounds are prohibited in-competition only, we explain why the pharmacokinetics of their main psychoactive compound, Δ9-tetrahydrocannabinol, may complicate the results management of adverse analytical findings. Passive inhalation does not appear to be a plausible explanation for a positive test. Although the prohibition of cannabinoids in sports is one of the most controversial issues in anti-doping, in this review we stress the reasons behind this prohibition, with strong emphasis on the evolving knowledge of cannabinoid pharmacology.

    Current sports injury reporting systems lack a common conceptual basis. We propose a conceptual foundation as a basis for the recording of health problems associated with participation in sports, based on the notion of impairment used by the World Health Organization. We provide definitions of sports impairment concepts to represent the perspectives of health services, the participants in sports and physical exercise themselves, and sports institutions. For each perspective, the duration of the causative event is used as the norm for separating concepts into those denoting impairment conditions sustained instantly and those developing gradually over time. Regarding sports impairment sustained in isolated events, 'sports injury' denotes the loss of bodily function or structure that is the object of observations in clinical examinations; 'sports trauma' is defined as an immediate sensation of pain, discomfort or loss of functioning that is the object of athlete self-evaluations; and 'sports incapacity' is the sidelining of an athlete because of a health evaluation made by a legitimate sports authority that is the object of time loss observations. Correspondingly, sports impairment caused by excessive bouts of physical exercise is denoted as 'sports disease' (overuse syndrome) when observed by health service professionals during clinical examinations, 'sports illness' when observed by the athlete in self-evaluations, and 'sports sickness' when recorded as time loss from sports participation by a sports body representative. We propose a concerted development effort in this area that takes advantage of concurrent ontology management resources and involves the international sporting community in building terminology systems that have broad relevance.

    Platelet rich plasma (PRP) is a powerful new biologic tool in sports medicine. PRP is a fraction of autologous whole blood containing and increased number of platelets and a wide variety of cytokines such as platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and transforming growth factor beta-1 (TGF-B1), fibroblast growth factor (FGF), Insulin-like growth factor-1 (IGF-1) among many others. Worldwide interest in this biologic technology has recently risen sharply. Basic science and preclinical data support the use of PRP for a variety of sports related injuries and disorders. The published, peer reviewed, human data on PRP is limited. Although the scientific evaluation of clinical efficacy is in the early stages, elite and recreational athletes already use PRP in the treatment of sports related injuries. Many questions remain to be answered regarding the use of PRP including optimal formulation, including of leukocytes, dosage and rehabilitation protocols. In this review, a classification for platelet rich plasma is proposed and the in-vitro, preclinical and human investigations of PRP applications in sports medicine will be reviewed as well as a discussion of rehabilitation after a PRP procedure. The regulation of PRP by the World Anti-Doping Agency will also be discussed. PRP is a promising technology in sports medicine; however, it will require more vigorous study in order to better understand how to apply it most effectively.

    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.

  9. The Impact of the Global Economic Crisis on Sport

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available The current economic crisis is the worst one in decades; it is surely the worst one the world has experienced since the Great Depression in the 1930s. Although it has affected countries with different positions in the global village in different ways and to different degrees, it has had worldwide consequences in most sub-systems of societies, including sport. These are hot issues in management and in everyday practice; still, relatively little attention has been paid to them within the social sciences. The objective of this paper is to close this gap by studying how the recent global economic crisis has affected sport. Two spheres of sport have been selected for analysis: mega sport events and grassroots sports. These two fields were chosen because of their social importance and because there is little scientific evidence about how they face and answer the challenges coming from the economic crisis. The topic is discussed from the theoretical perspective of the nexus of economy, politics, society, and culture. The methodological considerations refer to the lack of reliable sources for economic data related to sport. The results indicate that mega sport events have suffered less from the recession: there might be new actors, but the show goes on. The true loser is grassroots sport. Household impoverishment might lead to a decreased willingness of the individual practitioners to pay for sports goods and services and to a decreased contribution of volunteers working in sport. The funding models vary across countries, but generally both public and private funding has been reduced. In conclusion, it is underlined that no fields of sport have been left untouched by the current global economic crisis, but grassroots sports have suffered the most from it.

    2007-07-01

    Today, doping is no longer limited to the classical drugs with well known effects and side effects. Older generation anabolic steroids are used mainly in fitness and recreational sports. In contrast, due to doping tests, substances used in competitive sports include peptide hormones, medications not yet approved, and even specially developed drugs, such as designer steroids. Of the peptide hormones, particularly growth hormones (human growth hormone), erythropoietin and generics, insulin, and presumably insulin-like growth factor 1 are used. Substance groups potentially relevant for doping are selective androgen receptor modulators and gene therapy drugs. For most of these, there is no knowledge about side effects in healthy individuals, and no adequate doping tests. Therefore, anti-doping measures cannot rely solely on the continual improvement of doping analyses, but should include increased measures for doping prevention. Not only sports organizations, but also governmental agencies should be involved in developing and implementing these measures.

    Most high-grade renal injuries (American Association for Surgery of Trauma (AAST) grades III-V) result from motor vehicle collisions associated with numerous concomitant injuries. Sports-related blunt renal injury tends to have a different mechanism, a solitary blow to the flank. We hypothesized that high-grade renal injury is often isolated in sports-related renal trauma. We identified patients with AAST grades III-V blunt renal injuries from four level 1 trauma centres across the United States between 1/2005 and 1/2014. Patients were divided into "Sport" or "Non-sport" related groups. Outcomes included rates of hypotension (systolic blood pressure 110bpm), concomitant abdominal injury, and procedural/surgical intervention between sports and non-sports related injury. 320 patients met study criteria. 18% (59) were sports-related injuries with the most common mechanisms being skiing, snowboarding and contact sports (25%, 25%, and 24%, respectively). Median age was 24 years for sports and 30 years for non-sports related renal injuries (p=0.049). Males were more commonly involved in sports related injuries (85% vs. 72%, p=0.011). Median injury severity score was lower for sports related injuries (10 vs. 27, pinjury scale scores. Sports related trauma was more likely to be isolated without other significant injury (69% vs. 39% (psports and non-sports renal injuries (p=0.30). Sports injuries had lower transfusion (7% vs. 47%, psports vs. 18% non-sports, p=0.95). High-grade sports-related blunt renal trauma is more likely to occur in isolation without other abdominal or thoracic injuries and clinicians must have a high suspicion of renal injury with significant blows to the flank during sports activities.

    Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

    Beedie, Christopher J

    2007-01-01

    The paper examines the placebo effect in sports performance. The possibility that the placebo effect is a more common phenomenon than the quantity of published research would suggest is briefly addressed. It is suggested that the placebo control design often used in sports performance research masks any placebo effects and thus presents a false picture of the mechanisms underlying performance-enhancing interventions in the real world. An electronic survey was sent to 48 competitive, international and professional athletes. Questions related to the placebo effect in competitive sport. Thirty responses were received. Data indicate that the majority (97%) of respondents believe that the placebo effect can exert an influence on sports performance, and that a significant number (73%) have experienced what they defined as a placebo effect. Inductive content analysis reveals that these experiences fall into several categories such as explicit placebo effects, inadvertent false beliefs, ritual and reverse placebo effects. Furthermore, 10 respondents (33%) offer explanations as to the nature of the placebo effect. Again, inductive content analysis reveals that these explanations fall into several categories including deliberate changes in competitive strategy, belief/expectancy, faith in a third party, and marketing. Overall, responses support previous experimental research and anecdotal reports that have found a relationship between belief and sports performance. It is suggested that further research be structured to not simply control for the placebo effect, but to elucidate it. Key pointsA survey of 30 athletes revealed that 73% have experienced a placebo effect in sport.Athletes suggest several potential explanations for these effects.Findings support the idea that placebo effects might be common in sport.Researchers and practitioners should be aware of the possible impact of these effects on research findings and competitive performance.

  3. The impact of sport related stressors on immunity and illness risk in team-sport athletes.

    2018-06-19

    Elite team-sport athletes are frequently exposed to stressors that have the potential to depress immunity and increase infection risk. Therefore, the purpose of this review is to describe how team-sport stressors impact upon immune responses, along with exploring whether alterations in these markers have the potential to predict upper respiratory tract illness symptoms. Narrative review. Salivary secretory immunoglobulin A (SIgA) and T-cell markers have been shown to predict infection risk in individual endurance athletes. Papers discussing the impact of team-sport stressors on SIgA and T-cells were discussed in the review, studies discussing other aspects of immunity were excluded. Journal articles were sourced from PubMed, Web of science and Scopus. Key search terms included team-sport athletes, stressors, immunity, T-cells, cytokines, SIgA and upper respiratory illness. Most team-sport stressors appear to increase risk for illness. An association between reduced SIgA and increased illness incidence has been demonstrated. Intensive training and competition periods have been shown to reduce SIgA, however, it is less clear how additional stressors including extreme environmental conditions, travel, psychological stress, sleep disturbance and poor nutrition affect immune responses. Monitoring SIgA may provide an assessment of a team-sport athletes risk status for developing upper respiratory tract symptoms, however there is currently not enough evidence to suggest SIgA alone can predict illness. Team-sport stressors challenge immunity and it is possible that the combination of stressors could have a compounding effect on immunodepression and infection risk. Given that illness can disrupt training and performance, further research is required to better elucidate how stressors individually and collectively influence immunity and illness.

    The role of curricular activities for the formation of education, health and behavioural outcomes has been widely studied. Yet, the role of extra-curricular activities has received little attention. This study analyzes the effect of participation in sports clubs—one of the most popular extra-curricular activities among children. We use alternative datasets and flexible semi-parametric estimation methods with a specific way to use the panel dimension of the data to address selection into sports. We find positive and robust effects on children’s school performance and peer relations. Crowding out of passive leisure activities can partially explain the effects. PMID:27144474

    Nuclear medicine can synergistically contribute to the sports medicine field, in the management of sports-related stress injures. Bone scintigraphy is commonly requested for evaluation of athletes with pain. Three-Phase 99m Tc MDP Bone Scan has emerged as the imaging reference standard for diagnosing such injuries. The inherently high-contrast resolution of the bone scan allows early detection of bone trauma and becomes positive within six to seventy-two hours after the onset of symptoms. The bone scan is able to demonstrate stress injuries days to weeks before the radiograph

    2017-12-01

    Promotions for online sports betting during televised sports broadcasts are regularly viewed by millions of Australians, raising concerns about their impacts on vulnerable groups including at-risk and problem gamblers. This study examined whether responses to these promotions varied with problem gambling severity amongst 455 Australian Internet sports bettors participating in an online survey. Results indicated that young male Internet sports bettors are especially vulnerable to gambling problems, particularly if they hold positive attitudes to gambling sponsors who embed promotions into sports broadcasts and to the promotional techniques they use and this heightens the risk that alluring messages contribute to excessive gambling. As problem gambling severity increased, so too did recognition that these promotions have impacted negatively on their sports betting behaviour. Because a plethora of sports betting brands and promotions are now heavily integrated into sports coverage, social marketing efforts are needed to offset their persuasive appeal and counter the positive attitudes towards them that appear linked to excessive gambling amongst Internet sports bettors.

  7. International Sport Movement in the Context of the Global Problems of Mankind

    2015-04-01

    Full Text Available As a result of globalization process the world becomes more and more integrated, the role of “hard” power becomes lower, while the role of “soft” power, vice versa, increases. Sport as one of the most important spheres of human activities, faces both positive and negative effects of globalization. Sport has an important function in the concept of “soft” security, and this importance is evidenced by serious attention, paid by the United Nations and other international organizations. The UN established the International Day of port, and it organizes regular meetings and conferences devoted to sport. Plenty of the UN Organizations officially use sport to achieve their aims. Sports diplomacy is believed to have reconciling, uniting role; sport must contribute to resolution of the most part of contemporary global problems. Abilities of the Information age allow using positive effect caused by sport events with maximal benefits. There is understanding in the UN, that sport alone cannot solve all global problems, but it can relieve their consequences. Therefore sport is used to struggle over such problems, as poverty; peace and security problems; disarmament necessity; human rights and democracy problems; demography, ecology and energy problems, difficulties with medical care and provision. On the other hand, sport suffers from globalization; it loses its initial function of competition due to politicization and commercialization. Even new issues of confrontation appear because of sports. Only global governance over sport, establishment of general rules and clear goals and their joint accomplishment can allow the international sports movement become a real force in fight against global problems.

    Full Text Available Being a significant area of human activity, sport has multiple functions. One of the more important functions of sport, especially top sport, is the inventive heuristic function. Creative work, being a process of creating new values, represents a significant possibility for advancement of sport. This paper aims at pointing at the various dimensions of human creative work, at the creative work which can be seen in sport (in a narrow sense and at the scientific and practical areas which borderline sport. The method of theoretical analysis of different approaches to the phenomenon of creative work , both in general and in sport, was applied in this paper. This area can be systematized according to various criterion : the level of creative work, different fields where it appears, the subjects of creative work - creators etc. Case analysis shows that the field of creative work in sport is widening and deepening constantly. There are different levels of creativity not only in the system of training and competition, but in a wider social context of sport as well. As a process of human spirit and mind the creative work belongs not just to athletes and coaches, but also to all the people and social groups who's creative power manifests itself in sport. The classification of creative work in sport according to various criterion allows for heuristic function of sport to be explained comprehensively and to create an image how do the sparks of human spirit improve the micro cosmos of sport. A thorough classification of creative work in sport allows for a detailed analysis of all the elements of creative work and each of it’s area in sport. In this way the progress in sport , as a consequence of innovations in both competitions and athletes’ training and of everything that goes with those activities, can be guided into the needed direction more easily as well as studied and applied.

  12. Maximizing ROI (return on information)

    Energy Technology Data Exchange (ETDEWEB)

    McDonald, B.

    2000-05-01

    The role and importance of managing information are discussed, underscoring the importance by quoting from the report of the International Data Corporation, according to which Fortune 500 companies lost $ 12 billion in 1999 due to inefficiencies resulting from intellectual re-work, substandard performance , and inability to find knowledge resources. The report predicts that this figure will rise to $ 31.5 billion by 2003. Key impediments to implementing knowledge management systems are identified as : the cost and human resources requirement of deployment; inflexibility of historical systems to adapt to change; and the difficulty of achieving corporate acceptance of inflexible software products that require changes in 'normal' ways of doing business. The author recommends the use of model, document and rule-independent systems with a document centered interface (DCI), employing rapid application development (RAD) and object technologies and visual model development, which eliminate these problems, making it possible for companies to maximize their return on information (ROI), and achieve substantial savings in implementation costs.

    Most of the digital data transmitted are carried by optical fibres, forming the great part of the national and international communication infrastructure. The information-carrying capacity of these networks has increased vastly over the past decades through the introduction of wavelength division multiplexing, advanced modulation formats, digital signal processing and improved optical fibre and amplifier technology. These developments sparked the communication revolution and the growth of the Internet, and have created an illusion of infinite capacity being available. But as the volume of data continues to increase, is there a limit to the capacity of an optical fibre communication channel? The optical fibre channel is nonlinear, and the intensity-dependent Kerr nonlinearity limit has been suggested as a fundamental limit to optical fibre capacity. Current research is focused on whether this is the case, and on linear and nonlinear techniques, both optical and electronic, to understand, unlock and maximize the capacity of optical communications in the nonlinear regime. This paper describes some of them and discusses future prospects for success in the quest for capacity. © 2016 The Authors.

    A worldwide consensus for timing and criteria for return to sport after anterior cruciate ligament (ACL) reconstruction is lacking. The aim of the study was to survey among the Italian Society of Knee, Arthroscopy, Sport, Cartilage and Orthopaedic Technologies (SIGASCOT) members in order to evaluate their approaches to the return to sport after ACL reconstruction regarding timing and criteria. A web survey among the SIGASCOT members was performed, including 14 questions regarding technical and graft preferences, timing for return to training and competitive activity for contact and non-contact sports and criteria to allow return to sport. Totally, 123 members completed the questionnaire. Return to training sports was allowed within 6 month by 87 % for non-contact sports and by 53 % for contact sports. Return to competitive activity was allowed within 6 months by 48 % for non-contact sports and by 13 % for contact sports. Full ROM (77 %), Lachman test (65 %) and Pivot-Shift test (65 %) were the most used criteria to allow return to sport. The 90 % used at least one clinical score. The SIGASCOT members showed various approaches in the return to sport after ACL reconstruction, with differences between return to training or competitive activity, and between contact and non-contact sports. Six months was generally considered adequate by most of the members for the most demanding activities. The most used criteria to allow return to sport were manual testing. A clear definition of sport activities and more objective criteria for the return to sport are needed. Level V, expert opinion.

  18. Sport specific fitness testing of elite badminton players.

    There is a scarcity of descriptive data on the performance capacity of elite badminton players, whose fitness requirements are quite specific. The purpose of this paper is to investigate the physiological response of elite badminton players in a sport-specific fitness test. Twelve Hong Kong national badminton team players performed a field test on a badminton court. Six light bulbs were connected to a programming device causing individual bulbs to light up in a given sequence. The players were instructed to react to the flashes by running towards them, and striking shuttles mounted in the vicinity of the bulbs. Exercise intensity was controlled by altering the interval between successive lightings. A low correlation (r = 0.65) was found between the results of the field test and the rank-order list of subjects, based on an objective on-field physiological assessment and subjective ranking. This may be explained by the requirements of other factors besides physical fitness which contribute to success in elite level badminton competition. These factors may include, for example, technical skill, mental power, and aesthetic judgements on the court. Maximum mean (s.d.) heart rate data (187(8) beats.min-1) and blood lactate values (10.4(2.9) mmol.l-1) in this study showed that players were under maximal load during the field test. From the testing data, it seems reasonable to speculate that the intensity of level 3 (20 light pulses.min-1; 3.0 s.pulse-1) and level 4 (22 light pulses.min-1; 2.7 s.pulse-1) simulates the requirement of actual games energy expenditure of the Hong Kong badminton players exercising at close to their anaerobic threshold. The results also show that an estimate of fitness can be derived from measurements involving exercise closely resembling that which is specific for the sports activity in question. Improved training advice and guidance may result from such studies. PMID:8800846

    Despite recent efforts to blend sport and human rights, activism for children's rights in sport has historically been marginalised. The positive 'social legacy' of sport events frequently masks more problematic issues, including child exploitation. We argue that harms to children in hosting communities of major sporting events (MSEs) should be a focus for both research and intervention since the plight of such children is currently a political blind spot.

  5. PLACEBO EFFECTS IN COMPETITIVE SPORT: QUALITATIVE DATA

    Directory of Open Access Journals (Sweden)

    Christopher J. Beedie

    2007-03-01

    Full Text Available The paper examines the placebo effect in sports performance. The possibility that the placebo effect is a more common phenomenon than the quantity of published research would suggest is briefly addressed. It is suggested that the placebo control design often used in sports performance research masks any placebo effects and thus presents a false picture of the mechanisms underlying performance-enhancing interventions in the real world. An electronic survey was sent to 48 competitive, international and professional athletes. Questions related to the placebo effect in competitive sport. Thirty responses were received. Data indicate that the majority (97% of respondents believe that the placebo effect can exert an influence on sports performance, and that a significant number (73% have experienced what they defined as a placebo effect. Inductive content analysis reveals that these experiences fall into several categories such as explicit placebo effects, inadvertent false beliefs, ritual and reverse placebo effects. Furthermore, 10 respondents (33% offer explanations as to the nature of the placebo effect. Again, inductive content analysis reveals that these explanations fall into several categories including deliberate changes in competitive strategy, belief/expectancy, faith in a third party, and marketing. Overall, responses support previous experimental research and anecdotal reports that have found a relationship between belief and sports performance. It is suggested that further research be structured to not simply control for the placebo effect, but to elucidate it

    Full text: Sports injuries are common in individual who participate in sports and exercise related activities. In majority of sports related injuries such as stress fracture, periosteitits, acute stress reaction of bone, the radiological investigations are usually normal in early stages. These injuries can lead to serious complications if not detected early and managed properly. This study was jointly carried out in premier medical institutes. All patients were referred from premier sports institute of the country and also by orthopedic surgeons. All patients were subjected for relevant radiological investigations and 3 phase bone scan. Total number of cases included in this study was 70 (N=70) among which bone scan was positive for stress fracture in 45 patients and shin splint was detected in 15 patients and avulsion injury seen in 3 patients. However, only one patient showed features of avulsion injury in X ray and in 1 patient X-ray was inconclusive. Conclusion:-The study shows that 3 phase bone scan is the most sensitive and relatively an inexpensive study. Bone scan has the ability for early detection of sports injuries and provide physiological information and evaluate multiple sites in single examination.SPECT study will help in the diagnostic specificity.

    Sports activities are considered favourable for general health; nevertheless, a possible influence of sports practice on the development of early osteoarthritis (OA) is a cause for concern. A higher incidence of OA in knees and ankles of former high-impact sports players than in those of the normal population has been shown and it is still debatable whether the cause is either to be recognized generically in the higher number of injuries or in a joint overload. The possibility to address knee OA in its early phases may be strictly connected to the modification of specific extrinsic or intrinsic factors, related to the patient in order to save the joint from further disease progression; these include sport practice, equipment and load. Non-surgical therapies such as continuative muscles reinforce and training play a strong role in the care of athletes with early OA, particularly if professional. There is an overall agreement on the need of an early restoring of a proper meniscal, ligament and cartilage integrity in order to protect the knee and resume sports safely, whereas alignment is a point still strongly debatable especially for professional athletes. Remaining questions still to be answered are the risks of different sports in relation to one another, although an actual protective effect of low-impact sports, such as walking, swimming or cycling, has been recognized on the appearance or worsening of OA, the effect of continuing or ceasing to practice a sport on the natural history of early OA, and even following appropriate treatment is still unknown.

    2017-11-01

    Full Text Available ABSTRACT In the last 20 years, there was a growing interest in the study of the theoretical and applied issues surrounding psychophysiological processes underlying performance. The psychophysiological monitoring, which enables the study of these processes, consists of the assessment of the activation and functioning level of the organism using a multidimensional approach. In sport, it can be used to attain a better understanding of the processes underlying athletic performance and to improve it. The most frequently used ecological techniques include electromyography (EMG, electrocardiography (ECG, electroencephalography (EEG, and the assessment of electrodermal activity and breathing rhythm. The purpose of this paper is to offer an overview of the use of these techniques in applied interventions in sport and physical exercise and to give athletes, coaches and sport psychology experts new insights for performance improvement.

    Cannabis is on the list of prohibited substances in the practice of sport, although its performance enhancing effect has not yet been proved. Its popularity among the younger generations as a social drug puts cannabis at the top of the list of compounds detected by the anti-doping laboratories accredited by the World Anti-Doping Agency worldwide. The management of the results of urine analysis is quite difficult for the medical and disciplinary committees not only because of the social use of the substance, but also because of the interpretation of the analytical data from urine samples. This paper gives an overview of what is presently known about cannabis in relation with the practice of sport. Review of literature on the cannabis and exercise, its effect in the body, and the problems with interpretation of results when it is detected in urine. The paper outlines the major effects of cannabis in the context of its social use and its use for sport activities. The difficulties in the interpretation of urine sample analysis results because of the protracted excretion time of the main metabolite, long after the intake, are described. There is an urgent need for sport authorities to take measures necessary to avoid players misusing cannabis.

The results confirm that students believe that we live in a society which his generally thought only to its own benefit; they think that volunteering can not solve the problems in society; that people do not have enough experience with volunteering and people do not have time to volunteering; volunteering is for young people; in their family and among friends, there are no volunteers; everyone could be volunteer only if that wishes; do not believe that volunteering is a waste of time and it helps in future career. The prevalent number of students, regardless of the Faculty which they belong, rarely volunteered in areas outside of sport. Results also shows that students from sport faculties have less experience in volunteering in sport than students from other faculties, but this difference is not dramatic.

Opfattelsen, der går ud på, at sporten udgør frugtbar jord for dyrkelse af et moralsk sindelag, fordi sporten indeholder en moralsk dimension i kraft af sin egen-natur, understøttes ikke af den...... forholdet mellem sport og moral kom således til at bekræfte og delvist forklare empirien på området.

    2010-01-01

    A regular sport activity involves physical and psychological benefits helping to improve the quality of life at any age. This aspect is even more important in the developing age, when the sport takes on a role of training and education. In this context, instances directed to allow adolescent and young adults with heart disease to practice sports seem justified, and they're becoming more pressing since when the diagnostic and therapeutic advances, especially in cardiac surgery and in interventional hemodynamics, allow an increasing number of patients, previously allocated to physical inactivity, to lead an active lifestyle. However, we have to keep in mind that congenital heart disease population is varied, not only by the nature of the malformation, but also because in the same cardiopathy you can find subjects in "natural history" or after surgery and, between them, subjects treated with several techniques and different outcomes. This justifies the need for a close collaboration between sports doctors, cardiologists and heart surgeons, particularly in the management of the most difficult and delicate problems.

    Full Text Available Fatih Abut, Mehmet Fatih AkayDepartment of Computer Engineering, Çukurova University, Adana, TurkeyAbstract: Maximal oxygen uptake (VO2max indicates how many milliliters of oxygen the body can consume in a state of intense exercise per minute. VO2max plays an important role in both sport and medical sciences for different purposes, such as indicating the endurance capacity of athletes or serving as a metric in estimating the disease risk of a person. In general, the direct measurement of VO2max provides the most accurate assessment of aerobic power. However, despite a high level of accuracy, practical limitations associated with the direct measurement of VO2max, such as the requirement of expensive and sophisticated laboratory equipment or trained staff, have led to the development of various regression models for predicting VO2max. Consequently, a lot of studies have been conducted in the last years to predict VO2max of various target audiences, ranging from soccer athletes, nonexpert swimmers, cross-country skiers to healthy-fit adults, teenagers, and children. Numerous prediction models have been developed using different sets of predictor variables and a variety of machine learning and statistical methods, including support vector machine, multilayer perceptron, general regression neural network, and multiple linear regression. The purpose of this study is to give a detailed overview about the data-driven modeling studies for the prediction of VO2max conducted in recent years and to compare the performance of various VO2max prediction models reported in related literature in terms of two well-known metrics, namely, multiple correlation coefficient (R and standard error of estimate. The survey results reveal that with respect to regression methods used to develop prediction models, support vector machine, in general, shows better performance than other methods, whereas multiple linear regression exhibits the worst performance

  7. A New Augmentation Based Algorithm for Extracting Maximal Chordal Subgraphs.

    2015-02-01

    A graph is chordal if every cycle of length greater than three contains an edge between non-adjacent vertices. Chordal graphs are of interest both theoretically, since they admit polynomial time solutions to a range of NP-hard graph problems, and practically, since they arise in many applications including sparse linear algebra, computer vision, and computational biology. A maximal chordal subgraph is a chordal subgraph that is not a proper subgraph of any other chordal subgraph. Existing algorithms for computing maximal chordal subgraphs depend on dynamically ordering the vertices, which is an inherently sequential process and therefore limits the algorithms' parallelizability. In this paper we explore techniques to develop a scalable parallel algorithm for extracting a maximal chordal subgraph. We demonstrate that an earlier attempt at developing a parallel algorithm may induce a non-optimal vertex ordering and is therefore not guaranteed to terminate with a maximal chordal subgraph. We then give a new algorithm that first computes and then repeatedly augments a spanning chordal subgraph. After proving that the algorithm terminates with a maximal chordal subgraph, we then demonstrate that this algorithm is more amenable to parallelization and that the parallel version also terminates with a maximal chordal subgraph. That said, the complexity of the new algorithm is higher than that of the previous parallel algorithm, although the earlier algorithm computes a chordal subgraph which is not guaranteed to be maximal. We experimented with our augmentation-based algorithm on both synthetic and real-world graphs. We provide scalability results and also explore the effect of different choices for the initial spanning chordal subgraph on both the running time and on the number of edges in the maximal chordal subgraph.

  8. Maximizing Lumen Gain With Directional Atherectomy.

    2016-08-01

    To describe the use of a low-pressure balloon inflation (LPBI) technique to delineate intraluminal plaque and guide directional atherectomy in order to maximize lumen gain and achieve procedure success. The technique is illustrated in a 77-year-old man with claudication who underwent superficial femoral artery revascularization using a HawkOne directional atherectomy catheter. A standard angioplasty balloon was inflated to 1 to 2 atm during live fluoroscopy to create a 3-dimensional "lumenogram" of the target lesion. Directional atherectomy was performed only where plaque impinged on the balloon at a specific fluoroscopic orientation. The results of the LPBI technique were corroborated with multimodality diagnostic imaging, including digital subtraction angiography, intravascular ultrasound, and intra-arterial pressure measurements. With the LPBI technique, directional atherectomy can routinely achieve <10% residual stenosis, as illustrated in this case, thereby broadly supporting a no-stent approach to lower extremity endovascular revascularization. © The Author(s) 2016.

    This paper describes the strategies employed to increase the profitability of an existing ambulatory pharmacy operated by the hospital. Methods to generate new revenue including implementation of a home parenteral therapy program, a home enteral therapy program, a durable medical equipment service, and home care disposable sales are described. Programs to maximize existing revenue sources such as increasing the capture rate on discharge prescriptions, increasing "walk-in" prescription traffic and increasing HMO prescription volumes are discussed. A method utilized to reduce drug expenditures is also presented. By minimizing expenses and increasing the revenues for the ambulatory pharmacy operation, net profit increased from +26,000 to over +140,000 in one year.

    2007-08-01

    A majority of sports science research is undertaken in universities and dedicated research centres, such as institutes of sport. Reviews of literature analysing and categorising research have been carried out, but categories identified have been limited to research design and data gathering techniques. Hence there is a need to include categories such as discipline, subjects and targeted sport. A study was conducted using document analysis method to gather data that described and categorised performance-based sports science research projects in Australian universities and institutes of sport. An instrument was designed that could be used by researchers to analyse and profile research in the area of sports science. The instrument contained six categories: targeted sport, primary study area, participant type, research setting, methodology and data gathering techniques. Research documents analysed consisted of 725 original unpublished research reports/theses. Results showed that over two-thirds of research projects were targeted to specific sports and, of this group, nearly half involved four sports: cycling, rowing, athletics and swimming. Overall, physiology was the most researched scientific discipline. The most frequently used research method was experimental design, and the most frequently used data gathering technique was physiological (performance) measures. Two-thirds of research was conducted in laboratory settings, and nearly half of the research was conducted with elite or sub-elite athletes as participants/subjects. The findings of this study provide an overall synopsis of performance-based sports science research conducted in Australia over the last 20 years, and should be of considerable importance in the ongoing development of sports science research policy in Australia.

  14. Does mental exertion alter maximal muscle activation?

    Full Text Available Mental exertion is known to impair endurance performance, but its effects on neuromuscular function remain unclear. The purpose of this study was to test the hypothesis that mental exertion reduces torque and muscle activation during intermittent maximal voluntary contractions of the knee extensors. Ten subjects performed in a randomized order three separate mental exertion conditions lasting 27 minutes each: i high mental exertion (incongruent Stroop task, ii moderate mental exertion (congruent Stroop task, iii low mental exertion (watching a movie. In each condition, mental exertion was combined with ten intermittent maximal voluntary contractions of the knee extensor muscles (one maximal voluntary contraction every 3 minutes. Neuromuscular function was assessed using electrical nerve stimulation. Maximal voluntary torque, maximal muscle activation and other neuromuscular parameters were similar across mental exertion conditions and did not change over time. These findings suggest that mental exertion does not affect neuromuscular function during intermittent maximal voluntary contractions of the knee extensors.

    Area Under the ROC Curve (AUC) is often used to measure the performance of an estimator in binary classification problems. An AUC-maximizing classifier can have significant advantages in cases where ranking correctness is valued or if the outcome is rare. In a Super Learner ensemble, maximization of the AUC can be achieved by the use of an AUC-maximining metalearning algorithm. We discuss an implementation of an AUC-maximization technique that is formulated as a nonlinear optimization problem. We also evaluate the effectiveness of a large number of different nonlinear optimization algorithms to maximize the cross-validated AUC of the ensemble fit. The results provide evidence that AUC-maximizing metalearners can, and often do, out-perform non-AUC-maximizing metalearning methods, with respect to ensemble AUC. The results also demonstrate that as the level of imbalance in the training data increases, the Super Learner ensemble outperforms the top base algorithm by a larger degree.

The inclusive fitness concept allows biologists to treat organisms as akin to rational agents seeking to maximize a utility function. Here we develop this idea and place it on a firm footing by employing a standard decision-theoretic methodology. We show how the principle of inclusive fitness maximization and a related principle of qu...

  18. Direct catastrophic injury in sports.

    Boden, Barry P

    2005-11-01

    Catastrophic sports injuries are rare but tragic events. Direct (traumatic) catastrophic injury results from participating in the skills of a sport, such as a collision in football. Football is associated with the greatest number of direct catastrophic injuries for all major team sports in the United States. Pole vaulting, gymnastics, ice hockey, and football have the highest incidence of direct catastrophic injuries for sports in which males participate. In most sports, the rate of catastrophic injury is higher at the collegiate than at the high school level. Cheerleading is associated with the highest number of direct catastrophic injuries for all sports in which females participate. Indirect (nontraumatic) injury is caused by systemic failure as a result of exertion while participating in a sport. Cardiovascular conditions, heat illness, exertional hyponatremia, and dehydration can cause indirect catastrophic injury. Understanding the common mechanisms of injury and prevention strategies for direct catastrophic injuries is critical in caring for athletes.

    Recurrent instability following primary arthroscopic stabilization of the shoulder is a common complication. Young, athletic patients are at the greatest risk of recurring instability. To date, the literature contains insufficient description regarding whether return to sports is possible after revision arthroscopic Bankart repair. Patients presenting with recurrent instability after primary arthroscopic stabilization should expect limitations in terms of their ability to partake in sporting activities after revision surgery. Case series; Level of evidence, 4. Twenty athletes who underwent arthroscopic revision stabilization of the shoulder after failed primary arthroscopic Bankart repair were included in the study after completing inclusion and exclusion criteria surveys. Athletic Shoulder Outcome Scoring System (ASOSS), Shoulder Sport Activity Score (SSAS), and the Subjective Patient Outcome for Return to Sports (SPORTS) scores were determined to assess the participants' ability to partake in sporting activities. Furthermore, sport type and sport level were classified and recorded. To assess function and stability, Rowe, American Shoulder and Elbow Surgeons, Constant-Murley, and Walch-Duplay scores were measured and recorded. Follow-up consultations were carried out after a mean of 28.7 months. The mean age at follow-up examination was 27.75 years. At the time of follow-up, 70% of the patients were able to return to their original sporting activities at the same level. However, 90% of patients described a limitation in their shoulder when participating in their sports. At 28.7 months after surgery, the mean ASOSS score was 76.8; the SSAS score decreased from 7.85 before first-time dislocation to 5.35 at follow-up ( P SPORTS score was 5.2 out of 10 at the follow-up consultation. Function- and instability-specific scores showed good to excellent results. The mean external rotational deficit for high external rotation was 9.25°, and for low external rotation it was

    Overuse injuries in youth athletes are becoming increasingly common which may be a result of the prevalence of year-round specialized sport participation. Previous research has identified sport volume recommendations related to months per year, hours per week, and simultaneous participation in multiple sports leagues. Coaches are a primary influence on a youth athlete's decision to specialize in a single sport. Therefore, identifying coaches' baseline beliefs and perceptions is important for developing strategies to educate coaches about safe sport participation. A total of 253 youth sport coaches (207 males) completed an anonymous online questionnaire regarding knowledge of sport volume recommendations and attitudes and beliefs regarding sport specialization. Eligible participants were required to serve as a head or assistant coach of a youth sport team in the past 12 months whose members were between the ages of 12 and 18. Most coaches were unaware of recommendations regarding the maximum number of months per year (79.4%), hours per week in one sport (79.3%), or number of simultaneous leagues for an athlete to participate in to reduce injury (77.6%). Fewer than half (43.2%) of all coaches were "very" or "extremely" concerned about the risk of injury in youth sports. A majority (60.1%) believed that sport specialization was either "quite a bit" or "a great deal" of a problem. Two-thirds (67.2%) responded that year-round participation in a single sport was either "very" or "extremely" likely to increase an athlete's risk of injury. Although the responses to this survey were predominantly from coaches from one state, our results suggest that coaches are unaware of sport volume recommendations but are concerned about specialization. Future efforts are needed to communicate these recommendations to coaches in order to reduce the risk of overuse injury in youth sports.

    Feeling time-pressed has become ubiquitous. Time management strategies have emerged to help individuals fit in more of their desired and necessary activities. We provide a review of these strategies. In doing so, we distinguish between two, often competing, motives people have in managing their time: activity maximization and outcome maximization. The emerging literature points to an important dilemma: a given strategy that maximizes the number of activities might be detrimental to outcome maximization. We discuss such factors that might hinder performance in work tasks and enjoyment in leisure tasks. Finally, we provide theoretically grounded recommendations that can help balance these two important goals in time management. Published by Elsevier Ltd.

    2010-01-01

    We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the task for which a quantum state is used as the resource. TMESs are the states that can be used to carry out the task maximally. This concept may be more useful than that of a general maximally entangled state in the case of a multipartite system. We illustrate this idea by giving an operational definition of maximally entangled states on the basis of communication tasks of teleportation and superdense coding. We also give examples and a procedure to obtain such TMESs for n-qubit systems.

Successful rowing requires high anaerobic capacity and, therefore, high VO2max.These results show higher values of VO2max in sportsmen in regard to non-sportsmen, which is the result of training only.

  5. Sanctions for doping in sport

    2014-01-01

    Full Text Available Top-level sport imposes new and more demanding physical and psychological pressures, and the desire for competing, winning and selfassertion leads athletes into temptation to use prohibited substances in order to achieve the best possible results. Regardless of the fact that the adverse consequences of prohibited substances are well-known, prestige and the need to dominate sports arenas have led to their use in sports. Doping is one of the biggest issues in sport today, and the fight against it is a strategic objective on both global and national levels. World Anti-Doping Agency, the International Olympic Committee, international sports federations, national anti-doping agencies, national sports federations, as well as governments and their repressive apparatuses are all involved in the fight against doping in sport. This paper points to a different etymology and phenomenology of doping, the beginnings of doping in sport, sports doping scandals as well as the most important international instruments regulating this issue. Also, there is a special reference in this paper to the criminal and misdemeanor sanctions for doping in sport. In Serbia doping in sport is prohibited by the Law on Prevention of Doping in Sports which came into force in 2005 and which prescribes the measures and activities aimed at prevention of doping in sport. In this context, the law provides for the following three criminal offenses: use of doping substances, facilitating the use of doping substances, and unauthorized production and putting on traffic of doping substances. In addition, aiming at curbing the abuse of doping this law also provides for two violations. More frequent and repetitive doping scandals indicate that doping despite long-standing sanctions is still present in sports, which suggests that sanctions alone have not given satisfactory results so far.

    The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32-37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. The number of sport disciplines participated in was inversely associated with WC, the linear decrease averaging 1.38 cm (95% CI 1.10-1.65) per each additional sport discipline. The result persisted after adjustment for the main covariates, such as volume of PA and diet quality. Among dizygotic twin pairs discordant for sports participation (0-2 vs. 5 or more disciplines), the mean within-pair difference in WC was 4.8 cm (95% CI 0.4-9.1) for men and 11.2 cm (95% CI 4.4-18.0) for women; among discordant monozygotic pairs, no differences were observed. In men, all three types of sports were individually associated with smaller WC, while in women, only mixed and power sports showed this association. Participation in several sport disciplines and sport types was associated with smaller WC among young adults in their mid-30s. Shared genetic background may explain some of the associations.

    Spectators of the Olympic Games can enjoy a wide variety of sports, including strength, team, timed, endurance, and artistic sports. In the Olympic program, there are two synchronized events: synchronized diving and synchronized swimming. The precision of the synchronization of the athlete's movements and skills is an added feature of entertainment. Synchronized athletes have additional training requirements to perfect the synchronization of their skills. The physical demands on the athlete from the repetition of training required for the perfection of synchronization result in injuries unique to these sports. Although both traumatic and overuse injuries occur, overuse injuries are more common. As these disciplines are artistic, judged sports, these athletes also are susceptible to eating disorders and the female athlete triad. This article reviews the training regimen of these athletes and outlines the injuries and health concerns that are common in the synchronized sports.

The questionnaire included a topical module of the International Social Survey Program regarding leisure time and sports. Results showed that male subjects were more likely to participate in recreational sports to improve their appearance and on account of their personal interest. In addition to these factors, female subjects also experienced greater motivation to participate when Taiwanese athletes performed well in international sporting competitions. This study confirmed that the factors influencing enjoyment of recreational sports participation differ among men and women. These results can be used to better inform public health professionals and other regulatory organizations formulating physical activity intervention strategies.

This study confirmed that the factors influencing enjoyment of recreational sports participation differ among men and women. These results can be used to better inform public health professionals and other regulatory organizations formulating physical activity intervention strategies. PMID:25599374

    Full Text Available This study examines the gender differences in the enjoyment of recreational sports participation among Taiwanese adults. Data were obtained using the 2007 Taiwan Social Change Survey. The questionnaire included a topical module of the International Social Survey Program regarding leisure time and sports. Results showed that male subjects were more likely to participate in recreational sports to improve their appearance and on account of their personal interest. In addition to these factors, female subjects also experienced greater motivation to participate when Taiwanese athletes performed well in international sporting competitions. This study confirmed that the factors influencing enjoyment of recreational sports participation differ among men and women.

    Bodies are always present in organizations, yet they frequently remain unacknowledged or invisible including in sport organizations and sport management research. We therefore argue for an embodied turn in sport management research. The purpose of this article is to present possible reasons why scholars have rarely paid attention to bodies in sport organizations; to offer arguments why they should do so; and to give suggestions for what scholarship on bodies and embodiment might look like using various theoretical frameworks. Using the topic of diversity as an example, we explore what insights into embodiment and bodily practices the theoretical frameworks of Foucault, Bourdieu, Merleau-Ponty and Butler have to offer researchers and how these insights may lead to better understandings of organizational processes in sport.

    To examine differences in lung function among sports that are of a similar nature and to determine which anthropometric/demographic characteristics correlate with lung volumes and flows. This was a cross-sectional study involving elite male athletes (N = 150; mean age, 21  4 years) engaging in one of four different sports, classified according to the type and intensity of exercise involved. All athletes underwent full anthropometric assessment and pulmonary function testing (spirometry). Across all age groups and sport types, the elite athletes showed spirometric values that were significantly higher than the reference values. We found that the values for FVC, FEV1, vital capacity, and maximal voluntary ventilation were higher in water polo players than in players of the other sports evaluated (p respiratory system. That knowledge is particularly important when athletes present with respiratory symptoms such as dyspnea, cough, and wheezing. Because sports medicine physicians use predicted (reference) values for spirometric parameters, the risk that the severity of restrictive disease or airway obstruction will be underestimated might be greater for athletes.

    Sport-related concussion is a growing health concern in Australia. Public concern is focused on the incidence and potential long term consequences of concussion. Children may be more prone to concussion and take longer to recover. The Australian Institute of Sport and the Australian Medical Association have collaborated to present the most contemporary evidence-based information in a format appropriate for all stakeholders. This position statement aims to ensure that participant safety and welfare is paramount when dealing with concussion in sport.First aid principles apply in the management of the athlete with suspected concussion, including protection of the cervical spine. Tools exist for use by members of the community, allowing identification of key symptoms and signs that raise the suspicion of concussion. Medical professionals should use the Sport Concussion Assessment Tool 3, in conjunction with clinical assessment for the diagnosis of concussion. Clinical assessment includes mechanism of injury, symptoms and signs, cognitive functioning, and neurological assessment including balance testing. In any situation where concussion is suspected, the athlete must be immediately removed from sport and not be allowed to return to activity until they have been assessed by a medical practitioner. "If in doubt, sit them out."A diagnosis of concussion requires immediate physical and cognitive rest, followed by a structured, graduated return to physical activity. Children require a longer period of recovery from concussion. Algorithms are provided for use by medical and non-medically trained stakeholders in the recognition and management of concussion.

    Food and beverage marketing has been identified as a major driver of obesity yet sports sponsorship remains common practice and represents millions of dollars in advertising expenditures. Research shows that food and beverage products associated with sports (e.g., M&M's with National Association for Stock Car Auto Racing logo) generate positive feelings, excitement, and a positive self-image among adults and children. Despite this, self-regulatory pledges made by food companies to limit exposure of unhealthy products to children have not improved the nutritional quality of foods marketed to children. We reviewed the literature about sports-related food marketing, including food and beverage companies' use of sports sponsorships, athlete endorsements, and sports video games. This review demonstrates that sports sponsorships with food and beverage companies often promote energy-dense, nutrient-poor products and while many of these promotions do not explicitly target youth, sports-related marketing affects food perceptions and preferences among youth. Furthermore, endorsement of unhealthy products by professional athletes sends mixed messages; although athletes may promote physical activity, they simultaneously encourage consumption of unhealthy products that can lead to negative health outcomes. We argue that more athletes and sports organizations should stop promoting unhealthy foods and beverages and work with health experts to encourage healthy eating habits among youth.

    Social media (e.g., Facebook and Twitter) use has increased considerably since its inception; however, research examining the relationship between social media use and sport has not progressed as rapidly. The purpose of the current study was to explore the prevalence rates of Facebook use among athletes around and during sport competitions and to investigate the relationships between sport anxiety and Facebook use. Two hundred and ninety-eight athletes of varying levels completed measures for sport anxiety and Facebook use, which included descriptive information about Facebook use prior to, during and following competitions. Results indicated that 31.9% of athletes had used Facebook during a competition and 68.1% had accessed Facebook within 2 h prior to competition. Time spent on Facebook prior to competition was significantly (and positively) correlated with the concentration disruption component of sport anxiety. Furthermore, regression analyses revealed that having push notifications enabled on an athletes' phone predicted 4.4% of the variability in sport anxiety. The percentage of athletes who accessed Facebook within 2 h of, or during, a competition is somewhat alarming considering the importance of psychological preparation in sport, which may compromise optimal psychological readiness and may lead to increased sport anxiety.

  16. Artificial intelligence in sports biomechanics: new dawn or false hope?

    This article reviews developments in the use of Artificial Intelligence (AI) in sports biomechanics over the last decade. It outlines possible uses of Expert Systems as diagnostic tools for evaluating faults in sports movements ('techniques') and presents some example knowledge rules for such an expert system. It then compares the analysis of sports techniques, in which Expert Systems have found little place to date, with gait analysis, in which they are routinely used. Consideration is then given to the use of Artificial Neural Networks (ANNs) in sports biomechanics, focusing on Kohonen self-organizing maps, which have been the most widely used in technique analysis, and multi-layer networks, which have been far more widely used in biomechanics in general. Examples of the use of ANNs in sports biomechanics are presented for javelin and discus throwing, shot putting and football kicking. I also present an example of the use of Evolutionary Computation in movement optimization in the soccer throw in, which predicted an optimal technique close to that in the coaching literature. After briefly overviewing the use of AI in both sports science and biomechanics in general, the article concludes with some speculations about future uses of AI in sports biomechanics. Key PointsExpert Systems remain almost unused in sports biomechanics, unlike in the similar discipline of gait analysis.Artificial Neural Networks, particularly Kohonen Maps, have been used, although their full value remains unclear.Other AI applications, including Evolutionary Computation, have received little attention.

    This review aims to provide information on the time athletes will take to resume sports activity following ankle fractures. We systematically searched Medline (PubMED), EMBASE, CINHAL, Cochrane, Sports Discus and Google scholar databases using the combined keywords 'ankle fractures', 'ankle injuries', 'athletes', 'sports', 'return to sport', 'recovery', 'operative fixation', 'pinning', 'return to activity' to identify articles published in English, Spanish, French, Portuguese and Italian. Seven retrospective studies fulfilled our inclusion criteria. Of the 793 patients, 469 (59%) were males and 324 (41%) were females, and of the 356 ankle fractures we obtained information on, 338 were acute and 18 stress fractures. The general principles were to undertake open reduction and internal fixation of acute fractures, and manage stress fractures conservatively unless a thin fracture line was visible on radiographs. The best timing to return to sports after an acute ankle fracture is still undefined, given the heterogeneity of the outcome measures and results. The time to return to sports after an acute stress injury ranged from 3 to 51 weeks. When facing athletes with ankle fractures, associated injuries have to be assessed and addressed to improve current treatment lines and satisfy future expectancies. The best timing to return to sports after an ankle fracture has not been established yet. The ideas of the return to activity parameter and surgeon databases including sports-related information could induce research to progress.

    Marketing Management of sport and tourism does not just mean marketing of touristic sport products. Marketing management of sport and tourism can be divided into marketing of sport activities, events or infrastructure for people outside the location and marketing of tourism through sport activities, events and sport infrastructure. A system approach is introduced to serve as a model for explaining interrelations between the different elements in the sport and tourism context. As such destinat...

    Paralympic sport provides sporting opportunities for athletes with a disability, with the Paralympic Games as the main event. Participation in sport is, however, associated with a significant risk for sustaining injuries and illnesses. Our knowledge of sports-related injuries and illnesses in Paralympic sport is very limited and there are no large-scale epidemiological cohort studies. The purpose here is to present a protocol for a prospective longitudinal study: The Sports-Related Injuries and Illnesses in Paralympic Sport Study (SRIIPSS). An argument-based method for investigation of design problems was used to structure the study protocol. The primary requirement of the protocol is to allow prospective studies over time and include exposure to both training and competition. To reflect the complexity of Paralympic sport with athletes' pre-existing impairments, use of assistive equipment, pain and other and medical issues, it is required that the data collection system is specifically adapted to Paralympic sport. To allow the collection of data, at the same time as there is limited access to coaches and medical personnel, it is advantageous that data can be collected online directly from the athletes. Based on this a self-report athlete monitoring system will be developed, where the athletes can enter data weekly via their mobile phones or lap-tops. Data will be collected from around 100 Swedish Paralympic athletes for approximately 1 year, which will allow us to i) prospectively estimate the annual incidence of sports-related injuries and illnesses and ii) explore risk factors and mechanisms for sustaining sports-related injuries and illnesses based on athlete exposure and training loads. For effective implementation of injury and illness prevention measures, comprehensive epidemiological knowledge is required. This study will be the first prospective longitudinal self-report study of sports-related injuries and illnesses in Paralympic sport over a longer period

    Full Text Available Prior value studies in sport settings have been focused on participation rather than spectatorship. This study is an initial step in examining the values associated with spectator sports. Interviews and focus groups were utilized in this qualitative study within four progressive phases for triangulation, transferability, and constant comparative assessment. A total of 54 individuals participated in the study. Because values were subjectively perceived at the highest level of abstraction reflecting desirable preference experiences, the interviews were designed to include seven categories of questions: Three categories dealt with observed behaviors and implied metaphors, and four categories including questions comparing spectator sports and sport participation, religion, other leisure activities, and substitutes. Grounded data techniques guided the coding procedure. Using the transcriptions and notes from 26 interviews and three focus groups, five coders were used to provide evidence of interrater reliability. Based on the results of the data analyses, a 10-value-type framework was developed in relation to spectator sports: (a Enjoyment (pleasure and satisfaction, (b Sociability (social interaction through sport spectating, (c Identity (enhancing self-esteem, (d Status (pursuing social recognition, (e Moral, (f Spirituality (inner peace, strength, meaning, and purpose in life, (g Epistemic, (h Aesthetics, (i Ritual (sports spectating becomes a series of formal and serious acts followed regularly and invariably as end-experience, and (j no or negative values. Different from Kahle’s (1983, Maslow’s (1970a, and Schwartz’ (1992 value theories, the framework was specifically associated with spectator sports and is expected to better predict spectator sport behavior than does a scale measuring motivations of sports fans.
