    Australian Rules Football is played by numerous young Australians throughout winter each year. There have been a number of studies on professional and semi-professional footballers, establishing the nature and frequency of injuries within this football code. Medical cover of an amateur football club over the 1993 season allowed detailed recording of injuries over this period. The data collected revealed a markedly different injury profile to that seen previously. The injury rate in this study was 96 per 1000 player hours. The most common injury was concussion (15%), with hand fractures next most frequent (13.5%). The lower limb was the most common site of injury, with head and neck second and upper limb third. Injuries with an overuse component were seen less commonly in the amateur group while traumatic injuries were more frequent. The time allocated by amateur footballers to their sport is less than professional players, quite aside from the difference in skill level attained. Overuse injuries may be correspondingly much less frequent on a time basis alone. The increased incidence of traumatic injuries is postulated to be a manifestation of both less well developed skills and possibly less available and effective preventative measures such as ankle strapping and tape supplies. Considering the large number of young people playing amateur football and the significant time and cost of what are often relatively minor injuries, more work is required to establish what injuries are most common, and importantly, what measures can be taken to decrease their incidence.

    The progress of injury prevention research in Australian football to date has been slow despite its recognition as a public health goal. In particular, field-based studies to identify injury risk factors and evaluate the effectiveness of injury prevention strategies need to be undertaken to ensure safety gains in this sport. For these types of studies to be successful and complied with, considerable support is required from clubs, coaches and players. To date, the actual level of support for injury prevention research at the community-level of football has not been established. A survey of 82 club administrators and coaches from the Victorian Amateur Football Association was undertaken to determine the level of support for injury prevention research, along with incentives for, and barriers towards, participation in such research. The highest priorities for injury prevention research were given as the prevention of knee, hamstring and concussion injuries and investigation into the content of training programs. The most common incentives reported as being necessary for participation in injury prevention research were financial assistance (59.5%), more club staff (57.0%) and further education (36.7%). The most commonly reported barriers to research were the expertise (50.0%) and number of (48.8%) of club medical staff members. Overall community-level football club administrators and coaches rank the importance of injury prevention research highly. The findings of this study are positive for injury prevention researchers and suggest that clubs are keen to participate in such research.

    Anterior cruciate ligament (ACL) injuries are the most costly injuries in football at both professional and amateur levels (Orchard J, Seward H, McGivern J, Hood S. Intrinsic and extrinsic risk factors for anterior cruciate ligament injury in Australian footballers. Am J Sports Med 2001;29:196-200.). In this study video analysis of 34 ACL injuries in Australian football was performed to investigate the causes of these injuries. Factors that may have contributed to the cause of the injury were analysed, rated and reported. The factors analysed were: type of manoeuvre, direction the knee 'gave way', running speed, knee angle, cutting angle and if the player was accelerating or decelerating. The majority of the injuries analysed occurred in non-contact situations (56%). Of these 37% occurred during sidestepping manoeuvres, 32% in landing, 16% land and step, 10% stopping/slowing and 5% crossover cut manoeuvres. Ninety-two percent of the non-contact injuries occurred at extended knee angles of 30 degrees or less, which is also commonly known to place stress on the ACL and reduce the protective role of hamstrings. Over half (54%) of non-contact injuries occurred whilst decelerating. It would be expected that greater speed and angle cut too would increase the frequency of ACL injury. The results could not confirm this with most injuries occurring at running speeds of slow jogging to running and equal number of injuries occurred at cutting to angles of the ranges 15-45 degrees and 45-75 degrees. These results give greater understanding into potential causes or contributors of ACL injury and information to assist in the development of knee injury prevention programs. PMID:16807104

  4. Spinal-cord injuries in Australian footballers, 1960-1985.

    1987-08-01

    A review of 107 footballers who suffered a spinal-cord injury between 1960 and 1985 has been undertaken. Since 1977, the number of such injuries in Rugby Union, Rugby League and Australian Rules has increased, from an average of about two injuries a year before 1977 to over eight injuries a year since then. Rugby Union is clearly the most dangerous game, particularly for schoolboys; all of the injuries in schoolboy games for this code have occurred since 1977. This study has shown that collision at scrum engagement, and not at scrum collapse, is the way in which the majority of scrum injuries are sustained. These injuries are largely preventable, and suggestions for rule changes are made. Half the injured players recovered to Frankel grades D or E. The financial entitlements of those injured were grossly inadequate; this warrants action. A national register for spinal-cord injuries from football should be established to monitor the effects of desirable rule changes in Rugby Union and Rugby League. PMID:3600465

    Along with the enjoyment and the other positive benefits of sport participation, there is also the risk of injury that is elevated in contact sport. This review provides a summary of injury incidence in Australian rules football (ARF), identifies injury risk factors, assesses the efficacy of interventions to reduce injury risk and makes recommendations for future research. The most common injuries were found to be muscle strains, particularly hamstrings; joint ligament sprains, especially ankle; haematomas and concussion. The most severe joint injury was anterior cruciate ligament rupture. Mouthguards are commonly worn and have been shown to reduce orofacial injury. There is evidence that thigh pads can reduce the incidence of thigh haematomas. There is a reluctance to wear padded headgear and an attempt to assess its effectiveness was unsuccessful due to low compliance. The most readily identified risk factor was a history of that injury. There were conflicting findings as to the influence strength imbalances or deficit has on hamstring injury risk in ARF. Static hamstring flexibility was not related to risk but low hip flexor/quadriceps flexibility increased hamstring injury risk. High lower-limb and high hamstring stiffness were associated with an elevated risk of hamstring injury. Since stiffness can be modulated through strength or flexibility training, this provides an area for future intervention studies. Low postural balance ability was related to a greater risk of ankle injury in ARF, players with poor balance should be targeted for balance training. There are preliminary data signifying a link between deficiencies in hip range of motion and hip adductor strength with groin pain or injury. This provides support for future investigation into the effectiveness of an intervention for high-risk players on groin injury rate. Low cross-sectional area of core-region muscle has been associated with more severe injuries and a motor control exercise intervention

    Full Text Available Abstract Hamstring injuries are the most prevalent injury in Australian Rules football. There is a lack of evidence based literature on the treatment, prevention and management of hamstring injuries, although it is agreed that the etiology is complicated and multi-factorial. We present two cases of hamstring injury that had full resolution after spinal manipulation and correction of lumbar-pelvic biomechanics. There was no recurrence through preventative treatment over a twelve and sixteen week period. The use of spinal manipulation for treatment or prevention of hamstring injury has not been documented in sports medicine literature and should be further investigated in prospective randomized controlled trials.

    Hamstring injuries are the most common injury sustained by Australian Football players. Eccentric training has been proposed as a potential preventative strategy. This pilot randomised controlled trial (RCT) evaluated the effectiveness of a pre-season eccentric training program for preventing hamstring injuries at the community level of Australian Football. Seven amateur clubs (n=220 players) were recruited. Players were randomised within clubs to the intervention (eccentric exercise) or control (stretching) groups and randomisation was stratified according to previous history of hamstring injury. Five exercise sessions were completed over a 12-week period, three during the pre-season and two during the first 6 weeks of the season. Compliance was recorded and players were monitored for the season to collect injury and participation data. There was no difference between the control (n=106) or intervention (n=114) groups with respect to baseline characteristics. Only 46.8% of all players completed at least two program sessions. Compliance was poorest for the intervention group. Intention-to-treat analysis suggested that players in the intervention group were not at reduced risk of hamstring injury (RR 1.2, 95% CI: 0.5, 2.8). When only control and intervention group players who participated in at least the first two sessions were analysed, 4.0% of intervention and 13.2% of control group players sustained a hamstring injury (RR 0.3, 95% CI: 0.1, 1.4; p=0.098). The findings suggest that a simple program of eccentric exercise could reduce the incidence of hamstring injuries in Australian Football but widespread implementation of this program is not likely because of poor compliance.

    The incidence of injuries in footballers is described. Nearly half of footballer's injuries involve the knee, with vertical tearing of the meniscus being common; surgical intervention may be required. Approximately one third of injuries involve the ankle, and will often require immobilisation. Other injuries include muscle damage, spondylosis of L4 or L5, concussion, and dislocations. The importance of prompt and correct treatment of injuries is emphasised.

    All rugby and soccer players presenting to the Accident & Emergency department during the football season 1992-1993 (a total of 871) were prospectively studied to compare the injuries sustained in the two sports. The nature and site of injury, treatment required, age, fitness, experience and position of the player, situation giving rise to injury, and medical attention at the grounds were all analysed. The results show that rugby and soccer players had the same number of injuries, and while there were some differences in the nature of the injuries, there was no difference in overall severity. Rugby flankers and soccer goalkeepers are particularly at risk. Competitive matches produce more injuries than training sessions. Experience or fitness did not appear to be a factor and 45% of rugby injuries and 15% of soccer injuries were from school matches. Law changes (e.g. the rugby scrum and the use of gum-shields) have reduced some injuries, but other areas (e.g. jumping for the ball in soccer, rucks and mauls in rugby) also warrant consideration. There was one death, but no spinal cord injuries. Medical attention at the grounds was limited. Rugby injuries, therefore, do not appear to be more numerous or severe than soccer injuries. Law changes have been of benefit but they need to be enforced and perhaps more should be considered. Medical attention at sports grounds could be improved and Registers of injuries kept by the sporting bodies would be of benefit. PMID:8050871

  11. MONITORING OF LOWER LIMB COMFORT AND INJURY IN ELITE FOOTBALL

    Full Text Available The aim of the study was to examine the relation between lower limb comfort scores and injury and to measure the responsiveness of a lower limb comfort index (LLCI to changes over time, in a cohort of professional footballers. Lower limb comfort was recorded for each individual using a comfort index which assessed the comfort status of five anatomical segments and footwear. Specifically we tested the extent to which comfort zones as measured by the LLCI were related to injury measured as time loss events. The hypothesis for the study was that poor lower limb comfort is related to time loss events (training or match day. A total of 3524 player weeks of data was collected from 182 professional athletes encompassing three codes of football (Australian Rules, Rugby league, Rugby Union. The study was conducted during football competition periods for the respective football leagues and included a period of pre- season training. The results of regression indicated that poor lower limb comfort was highly correlated to injury (R2 =0.77 and accounted for 43.5 time loss events/ 1000hrs football exposure. While poor comfort was predictive of injury 47% of all time loss events it was not statistically relevant (R2 =0.18. The results indicate lower limb comfort can be used to assess the well-being of the lower limb; poor comfort is associated with injury, and the LLCI has good face validity and high criterion-related validity for the relationship between comfort and injury

  12. Imaging of American football injuries in children

    International Nuclear Information System (INIS)

    It is estimated that 3.2 million children ages 6 to 14 years participated in organized youth football in the United States in 2007. Approximately 240,000 children play football in the nation's largest youth football organization, with tackle divisions starting at age 5 years. The number of children playing unsupervised football is much higher, and the overall number of children participating in American football is increasing. Sports are the leading cause of injury-related emergency room visits for teenagers, and football is a leading precipitating athletic activity for these visits. Football is also the most hazardous organized sports in the United States. Though most pediatric football-related injuries are minor, such as abrasions, sprains, and strains of the extremities, football accounts for more major and catastrophic injuries than any other sport. Given football's popularity with children in the United States, combined with the high rate of injury associated with participation in this activity, radiologists should be familiar with the imaging features and injury patterns seen in this patient population.

    Full Text Available Abstract Background Hamstring injuries are the most common injury in Australian Rules football. It was the aims to investigate whether a sports chiropractic manual therapy intervention protocol provided in addition to the current best practice management could prevent the occurrence of and weeks missed due to hamstring and other lower-limb injuries at the semi-elite level of Australian football. Methods Sixty male subjects were assessed for eligibility with 59 meeting entry requirements and randomly allocated to an intervention (n = 29 or control group (n = 30, being matched for age and hamstring injury history. Twenty-eight intervention and 29 control group participants completed the trial. Both groups received the current best practice medical and sports science management, which acted as the control. Additionally, the intervention group received a sports chiropractic intervention. Treatment for the intervention group was individually determined and could involve manipulation/mobilization and/or soft tissue therapies to the spine and extremity. Minimum scheduling was: 1 treatment per week for 6 weeks, 1 treatment per fortnight for 3 months, 1 treatment per month for the remainder of the season (3 months. The main outcome measure was an injury surveillance with a missed match injury definition. Results After 24 matches there was no statistical significant difference between the groups for the incidence of hamstring injury (OR:0.116, 95% CI:0.013-1.019, p = 0.051 and primary non-contact knee injury (OR:0.116, 95% CI:0.013-1.019, p = 0.051. The difference for primary lower-limb muscle strains was significant (OR:0.097, 95%CI:0.011-0.839, p = 0.025.

J Strength Cond Res 30(8): 2129-2137, 2016-This study examined the relationship between movement demands, match events, and match performance in professional Australian football. Data were collected from 19 players using global positioning system units during 2 Australian Football League seasons. A range of movement demands and instantaneous power measures were collected. The players were divided into high-caliber (HC, ≥17/20) and low-caliber (LC, ≤8/20) groups based on the rating score by their coaches. A Mann-Whitney U-test, independent samples t-test, and effect sizes were used to determine whether any differences existed between the 2 groups. The HC group had a significantly higher match duration (7.2%), higher total distance (9.6%), and covered more distance and spent more time high-speed running per minute (12.7 and 11.9%). Although not significant, the effect sizes revealed that the HC group tended to have a higher mean metabolic power output (2.6%) and spent more time at the high power zone (7.9%). For the match event data, the HC group had significantly more involvements with the football. The results demonstrated the higher physical demands placed on the HC group. The findings suggest that analyzing instantaneous power measures can provide valuable information about the physical demands placed on team sport athletes to coaches and conditioning staff.

Eighty-six players from two elite under-age Australian football sides were screened weekly for hip adductor muscle strength, using a hand-held dynamometer and for the onset of groin pain. The maximum variation in the average hip adductor muscle strength values of the sample was a 2.6% decrease from baseline in week 7 of the study. Twelve players (14% of the sample studied) reported groin pain for two consecutive weeks and were considered to have an onset of groin injury. The mean hip adductor muscle strength of these players was decreased significantly from baseline by an average of 11.75+/-2.50% at the week of pain onset (F=264.76 (1,11), padductor muscle strength is decreased both preceding and during the onset of groin injury in elite under-age Australian footballers.

    Sports are spontaneous generators of stories. Through skill and chance, the script of each game is dynamically written in real time by players acting out possible trajectories allowed by a sport's rules. By properly characterizing a given sport's ecology of `game stories', we are able to capture the sport's capacity for unfolding interesting narratives, in part by contrasting them with random walks. Here, we explore the game story space afforded by a data set of 1,310 Australian Football League (AFL) score lines. We find that AFL games exhibit a continuous spectrum of stories and show how coarse-graining reveals identifiable motifs ranging from last minute comeback wins to one-sided blowouts. Through an extensive comparison with a random walk null model, we show that AFL games are superdiffusive and deliver a much broader array of motifs, and we provide consequent insights into the narrative appeal of real games.

    Sports are spontaneous generators of stories. Through skill and chance, the script of each game is dynamically written in real time by players acting out possible trajectories allowed by a sport's rules. By properly characterizing a given sport's ecology of "game stories," we are able to capture the sport's capacity for unfolding interesting narratives, in part by contrasting them with random walks. Here we explore the game story space afforded by a data set of 1310 Australian Football League (AFL) score lines. We find that AFL games exhibit a continuous spectrum of stories rather than distinct clusters. We show how coarse graining reveals identifiable motifs ranging from last-minute comeback wins to one-sided blowouts. Through an extensive comparison with biased random walks, we show that real AFL games deliver a broader array of motifs than null models, and we provide consequent insights into the narrative appeal of real games.

  16. EVALUATING AUSTRALIAN FOOTBALL LEAGUE PLAYER CONTRIBUTIONS USING INTERACTIVE NETWORK SIMULATION

    Directory of Open Access Journals (Sweden)

    Jonathan Sargent

    2013-03-01

    Full Text Available This paper focuses on the contribution of Australian Football League (AFL players to their team's on-field network by simulating player interactions within a chosen team list and estimating the net effect on final score margin. A Visual Basic computer program was written, firstly, to isolate the effective interactions between players from a particular team in all 2011 season matches and, secondly, to generate a symmetric interaction matrix for each match. Negative binomial distributions were fitted to each player pairing in the Geelong Football Club for the 2011 season, enabling an interactive match simulation model given the 22 chosen players. Dynamic player ratings were calculated from the simulated network using eigenvector centrality, a method that recognises and rewards interactions with more prominent players in the team network. The centrality ratings were recorded after every network simulation and then applied in final score margin predictions so that each player's match contribution-and, hence, an optimal team-could be estimated. The paper ultimately demonstrates that the presence of highly rated players, such as Geelong's Jimmy Bartel, provides the most utility within a simulated team network. It is anticipated that these findings will facilitate optimal AFL team selection and player substitutions, which are key areas of interest to coaches. Network simulations are also attractive for use within betting markets, specifically to provide information on the likelihood of a chosen AFL team list "covering the line".

Conversely, in soccer (football in Europe, teams in northern (cooler areas have higher rates of injury than those in southern (warmer areas, with an exception being knee anterior cruciate ligament (ACL injuries, which are more common in the southern (warmer parts of Europe. This study examined relative injury incidence in the AFL comparing 9,477 injuries over 229,827 player-weeks from 1999–2012. There was a slightly higher injury incidence for teams from warmer parts of Australia (relative risk [RR] 1.05, 95% confidence interval [CI] 1.01–1.10 with quadriceps strains (RR 1.32, 95% CI 1.10–1.58, knee cartilage injuries (RR 1.42, 95% CI 1.16–1.74, and ankle sprains (RR 1.17, 95% CI 1.00–1.37 all being more likely in warmer region teams. Achilles injuries followed a reverse pattern, tending to be more common in cooler region teams (RR 0.70, 95% CI 0.47–1.03. In conclusion, common findings from the AFL and European soccer are that ankle sprains and ACL injuries are generally more likely in teams playing in warmer climate zones, whereas Achilles tendinopathy may be more likely in teams playing in cooler zones.

    The risk of injury in football is high, but few studies have compared men's and women's football injuries. The purpose of this prospective study was to analyse the exposure and injury characteristics of European Championships in football and to compare data for men, women and male youth players. The national teams of all 32 countries (672 players) that qualified to the men's European Championship 2004, the women's European Championship 2005 and the men's Under-19 European Championship 2005 were studied. Individual training and match exposure was documented during the tournaments as well as time loss injuries. The overall injury incidence was 14 times higher during match play than during training (34.6 vs. 2.4 injuries per 1000 h, P women's championship had a significantly higher match injury incidence compared to teams going to the semi-finals (65.4 vs. 5.0 injuries per 1000 h, P = 0.02). Non-contact mechanisms were ascribed for 41% of the match injuries. One-fifth of all injuries were severe with absence from play longer than 4 weeks. In conclusion, injury incidences during the European Championships studied were very similar and it seems thus that the risk of injury in international football is at least not higher in women than in men. The teams eliminated in the women's championship had a significantly higher match injury incidence than the teams going to the final stage. Finally, the high frequency of non-contact injury is worrying from a prevention perspective and should be addressed in future studies. PMID:17375283

    International Nuclear Information System (INIS)

    Full text: The aim of this study was to examine relationships between MR parameters of hamstring injury and the amount of time lost from competition in Australian Rules footballers. Thirty seven footballers with suspected hamstring injury underwent T1 and inversion recovery T2 turbo spin-echo sequences in axial and sagittal planes. Presence and dimension of abnormal focal intramuscular and / or extramuscular T2 hyperintensity was independently recorded by two radiologists and the percentage abnormal cross sectional muscle area and abnormal muscle volume were measured from T2-weighted images depicting extent of muscle injury. MR detected hamstring muscle and linear extramuscle T2 hyperintensity in 30 (81%) and 25 (68%) of 37 athletes respectively, the long head of biceps being the dominant site of injury in 21 cases.There was a relationship between days lost from competition and percentage abnormal muscle area (r = 0.63, p 0.001) and volume of muscle affected (r = 0.46, p 0.01) with only a trend for linear extramuscular T2 hyperintensity (r = 0.33, p = 0.12) being demonstrated. Hamstring injury most frequently involved the long head of biceps femoris and recovery time was related to MR measurements such as the percentage of abnormal muscle area and volume of muscle injury.

    1994-07-01

    The incidence of injuries to the spinal cord sustained at rugby in South Africa, New Zealand and Australia is reviewed. Ninety-seven injuries seen at Stoke Mandeville Hospital at the National Spinal Injuries Centre (NSIC) between 1956 and 1993 are analysed in detail. There were 93 accidents at rugby union, two at American football and two at rugby league. The injuries were of the cervical spine apart from four hysterics and one thoracic injury. The thoracic injury occurred after the game when the player fell downstairs. The injuries were analysed according to the mechanism of injury, the neurological condition, the causation, the standard of the player and the position in the field. The injuries caused were the result of force being applied to the skull which was transmitted to the cervical spine resulting in injury to the cervical cord. As a result of this research, representations were made to the appropriate authorities and changes in the laws were made. As a result of these law changes there has been a dramatic reduction in the overall number of injuries and the elimination of the injury from the loose scrum. This paper discusses the historical sequence of how these preventative measures came about to reduce the incidence of injuries and the legal implications whereby the authors took part in two law suits. The legal consequences are analysed in detail. PMID:7970845

  14. Knee and ankle injuries from playing football

    International Nuclear Information System (INIS)

    Soccer is the most common sport activity worldwide. Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured. For sufficient radiological diagnosis knowledge of the biomechanics of the soccer game and some details about the history of the injury may be of help. To prevent soccer injuries or keep the degree of injury low, special programs had been developed. (orig.)

    Background: Prior research has described the anthropometric and physical performance characteristics of professional, collegiate, and high school American football players. Yet, little research has described these factors in American youth football and their potential relationship with injury. Purpose: To characterize anthropometric and physical performance measures, describe the epidemiology of injury, and examine the association of physical performance measures with injury among children participating within age-based divisions of a large metropolitan American youth football league. Study Design: Case-control study; Level of evidence, 3. Methods: Demographic, anthropometric, and physical performance characteristics and injuries of 819 male children were collected over a 2-year period (2011-2012). Injury data were collected by the league athletic trainer (AT) and coaches. Descriptive analysis of demographic, anthropometric, and physical performance measures (40-yard sprint, pro-agility, push-ups, and vertical jump) were conducted. Incidence rates were computed for all reported injuries; rates were calculated as the number of injuries per 1000 athlete-exposures (AEs). Multinomial logistic regression was used to identify whether the categories of no injury, no-time-loss (NTL) injury, and time-loss (TL) injury were associated with physical performance measures. Results: Of the 819 original participants, 760 (92.8%) completed preseason anthropometric measures (mean ± SD: age, 11.8 ± 1.2 years; height, 157.4 ± 10.7 cm; weight, 48.7 ± 13.3 kg; experience, 2.0 ± 1.8 years); 640 (78.1%) players completed physical performance measures. The mean (±SD) 40-yard sprint and pro-agility measures of the players were 6.5 ± 0.6 and 5.7 ± 0.5 seconds, respectively; the number of push-ups and maximal vertical jump height were 16.5 ± 9.3 repetitions and 42.3 ± 8.4 cm, respectively.

    2010-01-01

    Rugby union football has long been one of the most popular sports in the world. Its popularity and number of participants continue to increase in the United States. Until 1995, rugby union primarily was an amateur sport. Worldwide there are now flourishing professional leagues in many countries, and after a long absence, rugby union will be returning to the Olympic games in 2016. In the United States, rugby participation continues to increase, particularly at the collegiate and high school levels. With the increase in rugby professional athletes and the reported increase in aggressive play, there have been changes to the injury patterns in the sport. There is still significant need for further epidemiologic data as there is evidence that injury prevention programs and rule changes have been successful in decreasing the number of catastrophic injuries in rugby union.

    2010-05-01

    The Yo-Yo Intermittent Recovery (IR) Test is currently used to assess endurance performance in team sport athletes. However, to date, no data has been presented on its application to an elite junior Australian football (AF) playing group. Therefore, the aim of this study was to evaluate the Yo-Yo Intermittent Recovery Test Level 1 (IR1) ability to discriminate between junior AF players at two different playing standards and a group of non-athletic healthy males. Sixty age matched participants (16.6+/-0.5 years) spread over three groups (20 per group): elite junior footballers; sub-elite junior footballers; and non-athletic healthy males participated in this study. Participants undertook a single Yo-Yo test performance on an indoor basketball court for each group. A one-way ANOVA with Scheffe's post hoc analysis revealed the elite junior footballers covered a significantly greater total distance (p<0.001) and completed a significantly greater number of high-intensity efforts (p<0.001) in comparison to their sub-elite counterparts, whilst both AF groups performed significantly better (p<0.001) than the non-athletic healthy males. This study demonstrates the ability of the Yo-Yo IR1 to discriminate endurance performance between elite and sub-elite AF players, whilst further distinguishing AF players from a non-athletic healthy control group.

    Full Text Available Australian Football (AF is Australia's major football code. Despite research in other football codes, to date, no data has been published on the physiological responses of AF players during match play. Fifteen athletes (17.28 ± 0.76 yrs participated in four pre-season matches, sanctioned by Australian Football League (AFL Victoria, investigating Heart Rate (HR, Blood Lactate (BLa, Core Temperature (Tcore, and Hydration status. Match HR was measured continuously using HR monitors. BLa was measured via finger prick lancet at the end of each quarter of play. Tcore was measured by use of ingestible temperature sensor and measured wirelessly at the end of each quarter of play. Hydration status was measured using refractometry, measuring urine specific gravity, and body weight pre and post-match. Environmental conditions were measured continuously during matches. Results of HR responses showed a high exertion of players in the 85-95% maximum HR range. Elevated mean BLa levels, compared to rest, were observed in all players over the duration of the matches (p = 0.007. Mean Tcore rose 0.68 °C between start and end of matches. Mean USG increased between 0.008 g/ml (p = 0.001 with mean body weight decreasing 1.88 kg (p = 0.001. This study illustrates physiological responses in junior AF players playing in the heat as well as providing physiological data for consideration by AF coaching staff when developing specific training programs. Continued research should consider physiological measurements under varying environments, and at all playing levels of AF, to ascertain full physiological responses during AF matches.

    This study examined if a video decision-making task could discriminate talent-identified junior Australian football players from their non-talent-identified counterparts. Participants were recruited from the 2013 under 18 (U18) West Australian Football League competition and classified into two groups: talent-identified (State U18 Academy representatives; n = 25; 17.8 ± 0.5 years) and non-talent-identified (non-State U18 Academy selection; n = 25; 17.3 ± 0.6 years). Participants completed a video decision-making task consisting of 26 clips sourced from the Australian Football League game-day footage, recording responses on a sheet provided. A score of "1" was given for correct and "0" for incorrect responses, with the participants total score used as the criterion value. One-way analysis of variance tested the main effect of "status" on the task criterion, whilst a bootstrapped receiver operating characteristic (ROC) curve assessed the discriminant ability of the task. An area under the curve (AUC) of 1 (100%) represented perfect discrimination. Between-group differences were evident (P < 0.05) and the ROC curve was maximised with a score of 15.5/26 (60%) (AUC = 89.0%), correctly classifying 92% and 76% of the talent-identified and non-talent-identified participants, respectively. Future research should investigate the mechanisms leading to the superior decision-making observed in the talent-identified group. PMID:26019058

    Decision-making is a key component of an umpire's in-game performance, with each decision potentially having a direct impact on the result of the game. Additionally, umpires have to be physically fit to ensure they keep up with the gameplay. While research has identified the decision-making demands and running demands of umpires separately, few have explored the relationship between them. The aim of this investigation was to examine the relationship between physical exertion and decision-making performance of Australian football umpires at the sub-elite and junior levels. A total of 18 Australian football umpires (sub-elite, n = 10; junior n = 8) performed 10 × 300 m runs, with each repetition immediately followed by a video-based decision-making test, then 1 min of recovery. A Mann-Whitney U assessment indicated a significant difference between the sub-elite and junior level umpires for decision-making accuracy (U = 13.00, z = -2.43, P = 0.016, r = -0.5). However, there was no significant difference in response time (U = 28.00, z = -1.07, P = 0.315, r = -0.25). The sub-elite umpires completed the running efforts in significantly less time than the junior umpires (P running times for either skill level (P > 0.05). This suggests decision-making performance may not be affected by physical exertion. Therefore, it may be suggested coaches of football umpires allocate more time to the decision-making development of their umpires instead of focusing largely on the physical fitness side, as is currently the trend.

    Full Text Available American football is one of the leading causes of athletic-related injuries. Injury rates in female elite players are mostly unknown. We hypothesized that the injury rates of female was comparable to those in men’s football during practice, as well as games. From 2009 to 2011, injury data were collected from the German female national team during training camps, World Championship 2010 and International friendly matches. The injury was categorized by location on the body and recorded as fracture/dislocation, strain, concussion, contusion or other injury. Injury rates were determined based on the exposure of an athlete to a game or practice event. The injury rate was calculated as the ratio of injuries per 1000 athlete exposures (AE. The rate of injury was significantly higher during games (58.8/1000 AE than practices [16.3/1000 AE, (P<0.01]. Furthermore, the injury rate in the tryouts was significantly higher (24.05/1000 AE compared to other training sessions with the national team (11.24/1000 AE. Our findings show that the injury rates in female elite American football players can be compared to those described for male players. Higher injury rates during matches than in training should also be underlined.

    Full Text Available Football is currently the most popular sport in the world. The competitive nature of the sport makes it prone to injuries with the estimated frequency being 10 to 35 per 1000 playing hours (Dvorak and Junge, 2000. The aim of this study was to identify the injury patterns and rehabilitation periods with specific injuries in a premiership football club. Player injuries were retrospectively analysed from a local database (Microsoft Access 2000 at the Blackburn Rovers Football Club, UK from December 1998 to March 2004. The club physiotherapist and physician recorded details of all injuries sustained during both training and matches during that period. Clear distinctions were made between acute and overuse injuries and rehabilitation times for each injury were noted (Arnason et al., 2004. Data was analysed using SPSS (Chicago, Illinois, USA. Differences between the groups were assessed using the independent samples t-test. P values of < 0.05 were considered statistically significant. There were 483 injuries in 91 players. Of these 133 injuries occurred as a result of overuse and 350 as a result of direct trauma. 440 injuries were treated conservatively while 43 were treated operatively. Table 1 shows the range and number of injuries, which occurred during this period along with the average rehabilitation time for each injury. Injuries grouped as "Other" in table 1 accounted for less than 1% of all injuries and could not always be directly attributed to football even though this appeared to be the precipitating factor in all cases. There was no statistical difference between rehabilitation times for acute injuries (18 days, standard deviation 30 as compared to overuse injuries (20 days, standard deviation 39 (p = 0.640. The mean rehabilitation time however for injuries treated conservatively (15 days , standard deviation 24 as compared to injuries treated surgically (61 days, standard deviation 67 was found to be statistically significant (p = 0

    Full Text Available Abstract Background Our understanding of the effects of football code participation on low back pain (LBP is limited. It is unclear whether LBP is more prevalent in athletic populations or differs between levels of competition. Thus it was the aim of this study to document and compare the prevalence, intensity, quality and frequency of LBP between elite and semi-elite male Australian football code participants and a non-athletic group. Methods A cross-sectional survey of elite and semi-elite male Australian football code participants and a non-athletic group was performed. Participants completed a self-reported questionnaire incorporating the Quadruple Visual Analogue Scale (QVAS and McGill Pain Questionnaire (short form (MPQ-SF, along with additional questions adapted from an Australian epidemiological study. Respondents were 271 elite players (mean age 23.3, range 17–39, 360 semi-elite players (mean age 23.8, range 16–46 and 148 non-athletic controls (mean age 23.9, range 18–39. Results Groups were matched for age (p = 0.42 and experienced the same age of first onset LBP (p = 0.40. A significant linear increase in LBP from the non-athletic group, to the semi-elite and elite groups for the QVAS and the MPQ-SF was evident (p Conclusion Foolers in Australia have significantly more severe and frequent LBP than a non-athletic group and this escalates with level of competition.

    Full Text Available Background: Playing football, both at the amateur and professional level, associates an increased risk of injury. A documented report on injury location, type and incidence, in correlation with sports intensity, professionalism level and age, would be of support for implementing preventing measures and appropriate training programs, to reduce the incidence of football related injury. Objectives: This study aimed to assess the incidence, type and location of injuries during one season, in an amateur football club and design strategies and preventive measures. Patients and Methods: A population of 308 players were studied, aged between 5 and 29 years old (20 subjects over-19, 38 under-19, 38 under-16, 57 under-14, 57 under-12, 44 under-10 and 54 under-8 years old, respectively distributed over 20 teams. In total, 339 cases of injury occurred. Results: The population injured the most was the under-19 group and the most prevalent type of injuries was muscular (40.7% and ligament (16.5%. The most common location was the lower limbs (78.6% and, specifically, the thigh (39.8%. Physical load periods (September and February were highlighted as the months of highest incidence and the average number of visits per injury was 1.34. A statistically significant relationship between hours of training and injuries was noted. Conclusions: In the literature, there are similar publications, who studied these variables, separately. This work provides us with a certain amount of descriptive results, which may serve as a model for future research projects, performing interventions by coaches and medical services of football clubs, to reduce the injuries incidence, especially in the months of greatest physical load and, therefore, improve the performance. Football is a safe sport to practice, at any age, because injuries, regularly, are not serious and it is highly recommended, given the amount of health benefits obtained.

[Subjects] The subjects for this study were 10 football athletes (males) with a knee injury. [Methods] Measurements were performed by using Cybex dynamometer under uniform motion before and after the application of kinesio tape to the quadriceps and hamstring muscle. Maximal concentric knee extension and flexion at three angular velocities (60°/s, 120°/s, and 180°/s) were measured. [Results] A significant difference was found in peak torque and total work of the flexion at 120°/s and 180°/s, as well as in the average power of extension at 180°/s. [Conclusion] Though it is not the main therapy for muscle function in football athletes with injury, kinesio taping was an effective adjunct therapy.

    2011-11-01

    Football codes (rugby union, soccer, American football) train and play matches on natural and artificial turfs. A review of injuries on different turfs was needed to inform practitioners and sporting bodies on turf-related injury mechanisms and risk factors. Therefore, the aim of this review was to compare the incidence, nature and mechanisms of injuries sustained on newer generation artificial turfs and natural turfs. Electronic databases were searched using the keywords 'artificial turf', 'natural turf', 'grass' and 'inj*'. Delimitation of 120 articles sourced to those addressing injuries in football codes and those using third and fourth generation artificial turfs or natural turfs resulted in 11 experimental papers. These 11 papers provided 20 cohorts that could be assessed using magnitude-based inferences for injury incidence rate ratio calculations pertaining to differences between surfaces. Analysis showed that 16 of the 20 cohorts showed trivial effects for overall incidence rate ratios between surfaces. There was increased risk of ankle injury playing on artificial turf in eight cohorts, with incidence rate ratios from 0.7 to 5.2. Evidence concerning risk of knee injuries on the two surfaces was inconsistent, with incidence rate ratios from 0.4 to 2.8. Two cohorts showed beneficial inferences over the 90% likelihood value for effects of artificial surface on muscle injuries for soccer players; however, there were also two harmful, four unclear and five trivial inferences across the three football codes. Inferences relating to injury severity were inconsistent, with the exception that artificial turf was very likely to have harmful effects for minor injuries in rugby union training and severe injuries in young female soccer players. No clear differences between surfaces were evident in relation to training versus match injuries. Potential mechanisms for differing injury patterns on artificial turf compared with natural turf include increased peak torque and

Participants were recruited from an elite under 18 (U18) AF competition and classified into two groups; talent identified (State U18 Academy representatives; n = 42; 17.6 ± 0.4 y) and non-talent identified (non-State U18 Academy representatives; n = 42; 17.4 ± 0.5 y). Both groups completed a multi-dimensional assessment, which consisted of physical (standing height, dynamic vertical jump height and 20 m multistage fitness test), technical (kicking and handballing tests) and perceptual-cognitive (video decision-making task) performance outcome tests. A multivariate analysis of variance tested the main effect of status on the test criterions, whilst a receiver operating characteristic curve assessed the discrimination provided from the full assessment.

Five field positions were selected with observations recording the number and relative per cent of "working" efforts (jogging, running, and sprinting, "resting" efforts (walking and the total distances associated with "working" or "resting" efforts. Intra-observer reliability, using test- retest method, showed correlations were r = 0.98 or greater. The Wing position covered 11,877 m, the greatest total distance during an entire game, whilst the HBF and Centre positions both recorded 11,545 m and 11,537 m respectively and the Ruck position covered 9,203 m. The HBF recorded the greatest frequency of 'working' and 'resting' efforts (180 and 182 respectively, whilst the Wing (166 and 158, Centre (162 and 149 and Ruck (161 and 166 showed similarities in their results. The Wing position recorded the longest average distance per 'working' effort (58 m whilst the Centre position recorded the longest average distance per 'resting' effort (17 m. Results also show the completion of less total efforts and smaller total distances, in Under 18 players, recorded compared to professional senior AF data. The results from this study suggest that further in-depth research is required into movement patterns and game activity demands in this AF playing group

    Full Text Available This study investigated the positional movement patterns in elite junior Australian Football (AF. Thirty players (17.1 ± 0.9 years participating in this study were tracked over seven home games of the regular 2006 Victorian junior (Under 18 league season. Using lapsed-time video analysis, each position for an entire match was videotaped on three separate occasions over the course of the season. Data analysed included the number of individual efforts, duration and frequency of efforts; distance and percentage time for the classifications of standing, walking jogging, running and sprinting. Results showed that the midfield position travelled the greatest distance (4173 ± 238 m per quarter; p < 0.05; ES = .94 whilst the full forward/full back travelled the least (2605 ± 348 m per quarter, p < 0.05, ES = 1.21. For all positions, walking or jogging accounted for the greatest number of efforts (45-55%, conversely running and sprinting accounted for 5-13% of match efforts. The majority of efforts across all classifications were between 0-3.99 s. The data from this study provides further evidence that AF is an intermittent sport characterised by high intensity movements separated by low intensity movements at a ratio of one high intensity effort every 12-40 s. However, careful interpretation of the data is required when training junior AF players for specific positions, given the specific group studied.

    The goals of this study were to determine if the biomarkers of head injury, NSE and S100B, increased in serum following an American football game. Serum creatine kinase (CK) and cortisol levels were also measured to determine muscle damage and stress caused by the football game. NSE, S100B, CK, and cortisol were measured in the serum of 17 football players before and after a collegiate junior varsity football game. No head injuries were reported by the players, athletic training staff, or coaches yet both NSE (Pre-game: 7.0 μg•L-1 ± 2.2 versus Post-game: 13.1 μg•L-1 ± 7.0, P <0.001) and S100B (Pre-game: 0.013 μg•L-1 ± 0.012 versus Post-game: 0.069 μg•L-1 ± 0.036, P <0.001) increased significantly. Neither CK (Pre-game: 90.5 U•L-1 ± 41.9 versus Post-game: 120.2 U•L-1 ± 62.7, P = 0.116) nor cortisol (Pre-game: 369.2 nmoles•L-1 ± 159.8 versus Post-game: 353.0 nmoles•L-1 ± 170.5, P = 0.349) increased significantly following the football game. There was little correlation found between S100B and body mass (R2 = 0.029) or CK (R2 = 0.352) levels. Although serum NSE and S100B increase as a result of playing in an American football game, the values are similar to or lower than levels found following competition in other contact and non-contact sports. Furthermore, the lack of correlation between S100B and body mass or CK indicates that S100B increases independent of body mass or muscle injury. PMID:27387898

The injury was categorized by location on the body and recorded as fracture/dislocation, strain, concussion, contusion or other injury. Injury rates were determined based on the exposure of an athlete to a game or practice event. The injury rate was calculated as the ratio of injuries per 1000 athlete exposures (AE). The rate of injury was significantly higher during games (58.8/1000 AE) than practices [16.3/1000 AE, (Pfootball players can be compared to those described for male players. Higher injury rates during matches than in training should also be underlined. PMID:23066496

    The Life Event Scale for Adolescents (LES A) was used to gather data regarding the events that had occurred during the previous year from 114 high school football players. Injuries during the season were classified according to the National Athletic Injury/Illness Reporting System (NAIRS). The findings indicated that players who experienced more family instability, particularly those who experienced parental illnesses, separations, divorces and deaths, were more likely to sustain a significant injury. It is postulated that a player's mental or emotional state may increase his risk of injury. PMID:7451953

    Full Text Available Abstract Background Mental ill health, especially depression, is recognised as an important health concern, potentially with greater impact in rural communities. This paper reports on a project, Coach the Coach, in which Australian rural football clubs were the setting and football coaches the leaders in providing greater mental health awareness and capacity to support early help seeking behaviour among young males experiencing mental health difficulties, especially depression. Coaches and other football club leaders were provided with Mental Health First Aid (MHFA training. Method Pre-post measures of the ability of those club leaders undertaking mental health training to recognise depression and schizophrenia and of their knowledge of evidence supported treatment options, and confidence in responding to mental health difficulties were obtained using a questionnaire. This was supplemented by focus group interviews. Pre-post questionnaire data from players in participating football clubs was used to investigate attitudes to depression, treatment options and ability to recognise depression from a clinical scenario. Key project stakeholders were also interviewed. Results Club leaders (n = 36 who were trained in MHFA and club players (n = 275 who were not trained, participated in this evaluation. More than 50% of club leaders who undertook the training showed increased capacity to recognise mental illness and 66% reported increased confidence to respond to mental health difficulties in others. They reported that this training built upon their existing skills, fulfilled their perceived social responsibilities and empowered them. Indirect benefit to club players from this approach seemed limited as minimal changes in attitudes were reported by players. Key stakeholders regarded the project as valuable. Conclusions Rural football clubs appear to be appropriate social structures to promote rural mental health awareness. Club leaders, including many

    The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of -1 corresponded to a -4.9 ± 3.1 and -8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of -1 corresponded to a 0.43 ± 0.38 m·min(-1) and -0.02 ± 0.01 au·min(-1) change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of -1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session.

    Full Text Available Talent identification (TID is a pertinent component of the sports sciences, affording practitioners the opportunity to target developmental interventions to a select few; optimising financial investments. However, TID is multi-componential, requiring the recognition of immediate and prospective performance. The measurement of athletic movement skill may afford practitioners insight into the latter component given its augmented relationship with functional sport specific qualities. It is currently unknown whether athletic movement skill is a discriminant quality in junior Australian football (AF. This study aimed to discriminate talent identified junior AF players from their non-talent identified counterparts using a fundamental gross athletic movement assessment. From a total of 50 under 18 (U18 AF players; two groups were classified a priori based on selection level; talent identified (n = 25; state academy representatives and non-talent identified (n = 25; state-based competition representatives. Players performed a fundamental gross athletic movement assessment based on the Athletic Ability Assessment (AAA, consisting of an overhead squat, double lunge (left and right legs, single leg Romanian deadlift (left and right legs, and a push up (six movement criterions. Movements were scored across three assessment points using a three-point scale (resulting in a possible score of nine for each movement. A multivariate analysis of variance revealed significant between group effects on four of the six movement criterions (d = 0.56 – 0.87; p = 0.01 – 0.02. Binary logistic regression models and a receiver operating characteristic curve inspection revealed that the overhead squat score provided the greatest group discrimination (β(SE = -0.89(0.44; p < 0.05, with a score of 4.5 classifying 64% and 88% of the talent identified and non-talent identified groups, respectively. Results support the integration of this assessment into contemporary talent

    Wilkerson, GB, Gupta, A, Allen, JR, Keith, CM, and Colston, MA. Utilization of practice session average inertial load to quantify college football injury risk. J Strength Cond Res 30(9): 2369-2374, 2016-Relatively few studies have investigated the potential injury prevention value of data derived from recently developed wearable technology for measurement of body mass accelerations during the performance of sport-related activities. The available evidence has been derived from studies focused on avoidance of overtraining syndrome, which is believed to induce a chronically fatigued state that can be identified through monitoring of inertial load accumulation. Reduced variability in movement patterns is also believed to be an important injury risk factor, but no evidence currently exists to guide interpretation of data derived from inertial measurement units (IMUs) in this regard. We retrospectively analyzed archived data for a cohort of 45 National Collegiate Athletic Association Division 1-football bowl subdivision football players who wore IMUs on the upper back during practice sessions to quantify any associations between average inertial load measured during practice sessions and occurrence of musculoskeletal sprains and strains. Both the coefficient of variation for average inertial load and frequent exposure to game conditions were found to be strongly associated with injury occurrence. Having either or both of the 2 risk factors provided strong discrimination between injured and noninjured players (χ = 9.048; p = 0.004; odds ratio = 8.04; 90% CI: 2.39, 27.03). Our findings may facilitate identification of individual football players who are likely to derive the greatest benefit from training activities designed to reduce injury risk through improved adaptability to rapidly changing environmental demands.

    Football players are more to violent impacts and injuries more than any athlete in any other sport. Concussion or mild traumatic brain injuries were one of the lesser known sports injuries until the last decade. With the advent of modern technologies in medical and engineering disciplines, people are now more aware of concussion detection and prevention. These concussions are often overlooked by football players themselves. The cumulative effect of these mild traumatic brain injuries can cause long-term residual brain dysfunctions. The principle of concussion is based the movement of the brain in the neurocranium and viscerocranium. The brain is encapsulated by the cerebrospinal fluid which acts as a protective layer for the brain. This fluid can protect the brain against minor movements, however, any rapid movements of the brain may mitigate the protective capability of the cerebrospinal fluid. In this paper, we propose a wireless health monitoring helmet that addresses the concerns of the current monitoring methods - it is non-invasive for a football player as helmet is not an additional gear, it is efficient in performance as it is equipped with EEG nanosensors and 3D accelerometer, it does not restrict the movement of the user as it wirelessly communicates to the remote monitoring station, requirement of individual monitoring stations are not required for each player as the ZigBee protocol can couple multiple transmitters with one receiver. A helmet was developed and validated according to the above mentioned parameters.

    Acceleration is a significant feature of game-deciding situations in the various codes of football. However little is known about the acceleration characteristics of football players, the effects of acceleration training, or the effectiveness of different training modalities. This study examined the effects of resisted sprint (RS) training (weighted sled towing) on acceleration performance (0-15 m), leg power (countermovement jump [CMJ], 5-bound test [5BT], and 50-cm drop jump [50DJ]), gait (foot contact time, stride length, stride frequency, step length, and flight time), and joint (shoulder, elbow, hip, and knee) kinematics in men (N = 30) currently playing soccer, rugby union, or Australian football. Gait and kinematic measurements were derived from the first and second strides of an acceleration effort. Participants were randomly assigned to 1 of 3 treatment conditions: (a) 8-week sprint training of two 1-h sessions x wk(-1) plus RS training (RS group, n = 10), (b) 8-week nonresisted sprint training program of two 1-h sessions x wk(-1) (NRS group, n = 10), or (c) control (n = 10). The results indicated that an 8-week RS training program (a) significantly improves acceleration and leg power (CMJ and 5BT) performance but is no more effective than an 8-week NRS training program, (b) significantly improves reactive strength (50DJ), and (c) has minimal impact on gait and upper- and lower-body kinematics during acceleration performance compared to an 8-week NRS training program. These findings suggest that RS training will not adversely affect acceleration kinematics and gait. Although apparently no more effective than NRS training, this training modality provides an overload stimulus to acceleration mechanics and recruitment of the hip and knee extensors, resulting in greater application of horizontal power.

    Athletes participating in sport are exposed to a relatively high injury risk. Previous research has suggested that it could be possible to reduce sports injuries through psychological skills training. The purpose of this study was to examine the extent to which a cognitive behavioural biofeedback intervention could reduce the number of sports injuries in a sample of players in Swedish elite football high schools. Participants from four elite football high schools (16-19 years old) were divided into one experiment (n = 13) and one control group (n = 14). Participants were asked to complete three questionnaires to assess anxiety level (Sport Anxiety Scale), history of stressors (Life Event Scale for Collegiate Athletes) and coping skills (Athletic Coping Skills Inventory - 28) in a baseline measure. Mann-Whitney U-tests showed no significant differences in pre-intervention scores based on the questionnaires. The experimental group participated in a nine-week intervention period consisting of seven sessions, including: somatic relaxation, thought stopping, emotions/problem focused coping, goal setting, biofeedback training as well as keeping a critical incident diary. A Mann-Whitney U test showed no significant difference between the control and experimental group U (n1 = 13, n2 = 14) = 51.00, p = 0.054. However, considering the small sample, the statistical power (0.05 for present study), to detect effects was low. The results of the study are discussed from a psychological perspective and proposals for future research are given. Key pointsCognitive-behavioral training together with biofeedback training seems to be an effective strategy to decrease the occurrence of injuries.More intervention studies should be conducted applying existing biofeedback methodology, especially in the injury preventive area.Future research should develop a bio-psychological injury model aimed at predicting injury occurrence which describes the physiological stress responses and how they

    This study aimed to realize a prospective follow-up of the injuries occurring in female and male football players involved in the highest league in the Grand-Duchy of Luxembourg. Data concerning anthropometric characteristics and football activities were gathered in 125 female and 243 male football players via questionnaires at the beginning of the study. Then, a follow-up of moderate to severe injuries (> 15 days of interruption in football practice) was performed throughout the season 2013-2014. Sixteen injuries (injury incidence = 0.7 injuries/1000 h of exposure) were observed in 13 female football players (10.4%). These injuries concerned mainly the knee (n = 7; 43.7%), with capsules and ligaments being the most often concerned tissues (n = 7; 43.7%). In male football players, 41 severe injuries (injury incidence = 0.6 injuries/1000 h of exposure) were observed in 36 players (14.8%). These injuries concerned mainly the thighs (n = 12; 29.3%) and the muscles and tendons were the most often concerned tissues (n = 18; 43.9%). Injuries in football are predominantly located at the lower limbs, particularly the knees in female football players. The predominant muscle and tendon lesions of the thighs occurring in males could reveal that physical preparation is insufficient or inadequate for a number of players. Regarding these results, it is necessary to implement an injury prevention strategy. The "FIFA 11+" programme could be used as the basic method, but should be personalized according to sex. The injury collection methodology could be optimized with the use of an electronic database, such as the Training and Injury Prevention Platform for Sports (TIPPS). Beside the systematic recording of injury data (as well as the training load) by the players or the medical staff, this system allows to share of important information between stakeholders, follow-up the players, provide risk factor warnings and increase the awareness of the injury problem.

    Anterior cruciate ligament (ACL) injury causes long lay-off time and is often complicated with subsequent new knee injury and osteoarthritis. Female gender is associated with an increased ACL injury risk, but few studies have adjusted for gender-related differences in age although female players are often younger when sustaining their ACL injury. The objective of this three-cohort study was to describe ACL injury characteristics in teams from the Swedish men's and women's first leagues and from several European men's professional first leagues. Over a varying number of seasons from 2001 to 2009, 57 clubs (2,329 players) were followed prospectively and during this period 78 ACL injuries occurred (five partial). Mean age at ACL injury was lower in women compared to men (20.6 ± 2.2 vs. 25.2 ± 4.5 years, P = 0.0002). Using a Cox regression, the female-to-male hazard ratio (HR) was 2.6 (95% CI 1.4-4.6) in all three cohorts studied and 2.6 (95% CI 1.3-5.3) in the Swedish cohorts; adjusted for age, the HR was reduced to 2.4 (95% CI 1.3-4.2) and 2.1 (95% CI 1.0-4.2), respectively. Match play was associated with a higher ACL injury risk with a match-to-training ratio of 20.8 (95% CI 12.4-34.8) and 45 ACL injuries (58%) occurred due to non-contact mechanisms. Hamstrings grafts were used more often in Sweden than in Europe (67 vs. 34%, P = 0.028), and there were no differences in time to return to play after ACL reconstruction between the cohorts or different grafts. In conclusion, this study showed that the ACL injury incidence in female elite footballers was more than doubled compared to their male counterparts, but also that they were significantly younger at ACL injury than males. These findings suggest that future preventive research primarily should address the young female football player. PMID:20532869

    Full Text Available The aim of this study was to investigate the injury incidence and injury characteristics of a Spanish sub-elite professional football team during four consecutive seasons. A team was followed prospectively from the season 2003-2004 to 2006-2007 and individual player exposure and time loss injuries were recorded during all club training sessions and matches. A total of 313 time-loss injuries were recorded. The mean injury incidence was 10.9 injuries/1000 hours (5.2 injuries/1000 training hours and 44.1 injuries/1000 match hours. The injury incidence during competitive matches was higher (p 28 days absence was 0.4 injuries/1000 hours. The thigh was the most commonly (35% injured region and caused 29% of all competitive match absence. Muscle injuries in the four main groups of the lower limbs (hamstrings, adductors, quadriceps and calf muscles caused 43% of competitive match unavailability. The results of this study show that the risk to sustain a major injury in the course of the season was low for sub- elite footballers in comparison to elite players. Thigh strains were the first cause of absence in competition due to injury.

    This case highlights the need for cautious management and serial regular examination of trauma patients. A 22-year-old Caucasian male presented to the emergency department 4 h following an injury sustained during football training. He complained of the immediate onset of severe left upper quadrant and left flank pain. He subsequently developed frank haematuria. On initial review, he was haemodynamically stable. CT of the abdomen and pelvis showed a grade 4 renal trauma. Over the following 36 h, he remained haemodynamically stable. On serial abdominal examinations however, he developed a rigid abdomen and was noted to have a haemoglobin drop. Interval CT scan showed a progression of his injury and the presence of a haemoperitoneum. An emergency laparotomy was performed resulting in a left nephrectomy. He made an uneventful recovery.

    Full Text Available The aim of this study was to investigate the match and training injury incidence, injury patterns and severity, and their monthly variation in a Hong Kong male professional football league. The study design was a prospective cohort study. Seven teams in the Hong Kong Football Association first division league and 152 players from 10 professional teams participated in this study. On a weekly basis throughout the 9-month season, time-loss injuries and individual exposure were collected from injury recorders team visits. Operational injury definitions and procedures followed the recommendations of a football consensus. The overall injury incidence was 7.4 injuries/1000 player hours and 296 injuries were recorded. The relative risk of match injury was 17 times greater than the risk of training injury [relative ratio (RR, 17.3; 95% confidence injury (CI, 11.6–25.7; p < 0.001]. Ankle sprain was the most common injury type (16.2% of all injuries and 52% of these injuries were recurrent. Thigh strain was the second most common injury type with 82% of the injuries involving the hamstring muscle and 80% of hamstring strains were noncontact injuries. During the competitive season, the relative risk of injury was highest in October (RR, 6.8; 95% CI, 6.7–6.9; p < 0.001 and February (RR, 4.7; 95% CI, 4.3–5.2; p < 0.001. This highlighted that Hong Kong professional football has a high match injury incidence. The relative risk of injury was highest at the beginning of the competitive season. A prospective multicentre epidemiological study is warranted to examine regional differences in injury risks. Coaches, players, health professionals, and researchers should join their efforts to investigate the effect on injury incidence and injury pattern associated with the duration and content of the preseason period, and the number of friendly matches held during preseason.

    Stress-injury models of health suggest that athletes experience more physical injuries during times of high stress. The purpose of this study was to evaluate the effect of increased physical and academic stress on injury restrictions for athletes (n = 101) on a division I college football team. Weeks of the season were categorized into 3 levels: high physical stress (HPS) (i.e., preseason), high academic stress (HAS) (i.e., weeks with regularly scheduled examinations such as midterms, finals, and week before Thanksgiving break), and low academic stress (LAS) (i.e., regular season without regularly scheduled academic examinations). During each week, we recorded whether a player had an injury restriction, thereby creating a longitudinal binary outcome. The data were analyzed using a hierarchical logistic regression model to properly account for the dependency induced by the repeated observations over time within each subject. Significance for regression models was accepted at p ≤ 0.05. We found that the odds of an injury restriction during training camp (HPS) were the greatest compared with weeks of HAS (odds ratio [OR] = 2.05, p = 0.0003) and LAS (OR = 3.65, p < 0.001). However, the odds of an injury restriction during weeks of HAS were nearly twice as high as during weeks of LAS (OR = 1.78, p = 0.0088). Moreover, the difference in injury rates reported in all athletes during weeks of HPS and weeks of HAS disappeared when considering only athletes that regularly played in games (OR = 1.13, p = 0.75) suggesting that HAS may affect athletes that play to an even greater extent than HPS. Coaches should be aware of both types of stressors and consider carefully the types of training methods imposed during times of HAS when injuries are most likely.

    Full Text Available Abstract Background Knee injuries in football are common regardless of age, gender or playing level, but adolescent females seem to have the highest risk. The consequences after severe knee injury, for example anterior cruciate ligament (ACL injury, are well-known, but less is known about knee injury prevention. We have designed a cluster randomized controlled trial (RCT to evaluate the effect of a warm-up program aimed at preventing acute knee injury in adolescent female football. Methods In this cluster randomized trial 516 teams (309 clusters in eight regional football districts in Sweden with female players aged 13–17 years were randomized into an intervention group (260 teams or a control group (256 teams. The teams in the intervention group were instructed to do a structured warm-up program at two training sessions per week throughout the 2009 competitive season (April to October and those in the control group were informed to train and play as usual. Sixty-eight sports physical therapists are assigned to the clubs to assist both groups in data collection and to examine the players' acute knee injuries during the study period. Three different forms are used in the trial: (1 baseline player data form collected at the start of the trial, (2 computer-based registration form collected every month, on which one of the coaches/team leaders documents individual player exposure, and (3 injury report form on which the study therapists report acute knee injuries resulting in time loss from training or match play. The primary outcome is the incidence of ACL injury and the secondary outcomes are the incidence of any acute knee injury (except contusion and incidence of severe knee injury (defined as injury resulting in absence of more than 4 weeks. Outcome measures are assessed after the end of the 2009 season. Discussion Prevention of knee injury is beneficial for players, clubs, insurance companies, and society.

    The role of referees has become a central issue in the investigation of home advantage. The main aim of this study was a thorough examination of the referee bias concerning injury time in football, which is currently seen as an important example for the assertion that referees contribute to home advantage. First, we use archival data from the German Bundesliga (seasons 2000/2001-2010/2011) to confirm the existence of an asymmetry in the allocation of injury time. We show this asymmetry to be a bias by ruling out hitherto remaining alternative explanations (effect = 18 s, P team leads in the game compared to a draw (effect = 21 s, P = 0.004, R2(adj) = 0.06). Third, the quantitative benefit of home or away teams in goals and points due to these biases is assessed. Overall, referee decisions on injury time indeed reveal biases, but they do not contribute to the home advantage, that is, there is no significant effect on goals scored by the teams. The qualitative findings (a new bias on injury time) as well as the quantitative findings (no overall effect) shed new light on the role of referees for home advantage.

    Background: Anterior cruciate ligament (ACL) injuries can have negative consequences on the careers of National Football League (NFL) players, however no study has ever analyzed the financial impact of these injuries in this population. Purpose: To quantify the impact of ACL injuries on salary and career length in NFL athletes. Study Design: Cohort study; Level of evidence, 3. Methods: Any player in the NFL suffering an ACL injury from 2010 to 2013 was identified using a comprehensive online search. A database of NFL player salaries was used to conduct a matched cohort analysis comparing ACL-injured players with the rest of the NFL. The main outcomes were the percentage of players remaining in the NFL and mean salary at 1, 2, 3, and 4 years after injury. Cohorts were subdivided based on initial salary: group A, $2,000,000. Mean cumulative earnings were calculated by multiplying the percentage of players remaining in the league by their mean salaries and compounding this each season. Results: NFL athletes suffered 219 ACL injuries from 2010 to 2013. The 7504 other player seasons in the NFL during this time were used as controls. Significantly fewer ACL-injured players than controls remained in the NFL at each time point (P < .05). In group A, significantly less ACL-injured players remained in the NFL at 1 to 3 seasons after injury (P < .05), and in group B, significantly less ACL-injured players remained in the NFL at 1 and 2 seasons after injury (P < .05). There was no significant decrease in group C. Players in groups A and B remaining in the NFL also had a lower mean salary than controls (P < .05 in season 1). The mean cumulative earnings over 4 years for ACL-injured players was $2,070,521 less per player than uninjured controls. Conclusion: On average, ACL-injured players earned $2,070,521 less than salary-matched controls over the 4 years after injury. Players initially earning less than $2 million per year have lower mean salaries and are less likely to remain

    In 2009, FIFA promoted and disseminated the FIFA 11+ injury prevention programme worldwide. Developed and studied by the FIFA Medical Assessment and Research Centre (F-MARC), the programme was based on a randomised controlled study and one countrywide campaign in amateur football that significantly reduced injuries and healthcare costs. Since the FIFA 11+ launch, key publications have confirmed the preventive effects of the programme and have evaluated its performance effects in female as well as male amateur football players. Furthermore, implementation strategies of this prevention programme have also been studied. The goal of this narrative review was to summarise the available scientific evidence about the FIFA 11+ programme. While FIFA continues to disseminate and implement FIFA 11+ among its Member Associations, adaptations of the injury prevention programme for children and referees have been developed and are currently being evaluated.

    Objectives: The purpose of this study is to determine if a pre-existing lumbar diagnosis such as spondylosis, a herniated lumbar disc, or spondylolysis affects a football player’s draft status or his performance and longevity in the NFL. Methods: The written medical evaluations and imaging reports of prospective professional American football athletes from 2003-2011 from one NFL franchise during the NFL combine (annual college football player evaluation prior to the NFL draft) were compiled and evaluated. All players were evaluated for a pre-existing lumbar diagnosis which were compiled from previous injury/medical records including radiographic imaging reports. Those players with a lumbar spine diagnosis and with appropriate radiograph, MRI and CT imaging were included in this study. These athletes were then matched by age, position, year, and round drafted to control draftees without a lumbar spine diagnosis. Career statistics were compiled including length of play and number of games started. Additionally, a previously established “Performance Score” was calculated for all players excluding offensive linemen. The continuous variables of each cohort were compared using a two-sided (tailed) Student’s t-test for normally distributed data. A chi-squared analysis was performed to analyze the categorical data. Statistical significance was accepted with a p < 0.05. Results: Out of a total of 2,965 athletes evaluated from the NFL combine, 414 players were identified with a pre-existing lumbar spine diagnosis. Athletes who attended the NFL combine without a lumbar spine diagnosis were significantly more likely to be drafted than those with one (74% vs. 61% respectively, p < 0.01). There was no difference between the investigational and control group with regard to round drafted, age, year drafted, or position. Overall, athletes with a lumbar spine injury compared to the control group had no difference in the number of years played (4.0 vs. 4.3 years, respectively

    OBJECTIVES: Children presenting with sport related injuries (SRIs) as a result of soccer, rugby and gaelic football are frequently seen in an emergency medicine (EM) setting in Ireland. A comparison of the demographics of injuries in these three sports has however not previously been performed. The purpose of this study was to provide up-to-date data on the nature of these SRIs. METHOD: Data was collected retrospectively on all children (<17 years of age), injured in these three sports, presenting to an emergency medicine department over 6 months, and was entered into a database for analysis. RESULTS: Retrospective analysis was performed on 23,000 charts, and 409 SRIs were identified over a 6-month period. None of the children reported using any form of protective gear, and 27% reported a previous presentation to the emergency department with a SRI. Most injuries were as a result of soccer (56%), with 24% occurring in gaelic football, and 20% occurring in rugby. The predominant mechanism of injury was different in each sport, in soccer-falls (38%), in gaelic football-collisions with objects (balls) (37%), and in rugby-collision with persons (55%). Although the predominant type of injury in soccer and gaelic football was a fracture, accounting for 50% and 42% of injuries, respectively, in rugby however, skin\\/soft tissue injuries presented more commonly, accounting for 44% of injuries. When the general site of injury was investigated, the upper limb accounted for the majority of SRIs in each sport. In the management of SRIs, oral analgesics were prescribed in 50%, however, it was observed that no use was made of topical, intramuscular or rectal analgesic routes of administration. In addition it was observed that RICE\\/general injury advice was given in only 27%, physiotherapy was requested in 2%, and no injury prevention advice was given to any child. Overall, 8% required admission. CONCLUSIONS: The data provided from this study may raise awareness of the nature

    Full Text Available Abstract Background Data on the incidence, nature, severity and cause of match football injuries sustained on dirt field are scarce. The objectives of this study was to compare the incidence, nature, severity and cause of match injuries sustained on dirt field and artificial turf field by amateur male football players. Methods A prospective two-cohort design was employed. Participants were 252 male football players (mean age 27 years, range 18-43 in 14 teams who participated in a local championship carried on a dirt field and 216 male football players (mean age 28 years, range 17-40 in 12 teams who participated in a local championship carried on a artificial turf field in the same zone of the city. Injury definitions and recording procedures were compliant with the international consensus statement for epidemiological studies of injuries in football. Results The overall incidence of match injuries for men was 36.9 injuries/1000 player hours on dirt field and 19.5 on artificial turf (incidence rate ratio 1.88; 95% CI 1.19-3.05. Most common injured part on dirt field was ankle (26.7% and on artificial turf was knee (24.3%. The most common injury type in the dirt field was skin injuries (abrasion and laceration and in the artificial turf was sprain and ligament injury followed by haematoma/contusion/bruise. Most injuries were acute (artificial turf 89%, dirt field 91% and resulted from player-to-player contact (artificial turf 59.2%, dirt field 51.4%. Most injuries were slight and minimal in dirt field cohort but in artificial turf cohort the most injuries were mild. Conclusions There were differences in the incidence and type of football match injuries sustained on dirt field and artificial turf.

    We use computational simulations to compare the impact response of different football and U.S. Army helmet pad materials. We conduct experiments to characterize the material response of different helmet pads. We simulate experimental helmet impact tests performed by the U.S. Army to validate our methods. We then simulate a cylindrical impactor striking different pads. The acceleration history of the impactor is used to calculate the Head Injury Criterion for each pad. We conduct sensitivity studies exploring the effects of pad composition, geometry, and material stiffness. We find that: (1) The football pad materials do not outperform the currently used military pad material in militarily-relevant impact scenarios; (2) Optimal material properties for a pad depend on impact energy; and (3) Thicker pads perform better at all velocities. Our analysis suggests that by using larger helmet shells with correspondingly thicker pads, impact-induced traumatic brain injury may be significantly reduced. Keywords: helmet,...

  15. Tackling in Youth Football.

    2015-11-01

    American football remains one of the most popular sports for young athletes. The injuries sustained during football, especially those to the head and neck, have been a topic of intense interest recently in both the public media and medical literature. The recognition of these injuries and the potential for long-term sequelae have led some physicians to call for a reduction in the number of contact practices, a postponement of tackling until a certain age, and even a ban on high school football. This statement reviews the literature regarding injuries in football, particularly those of the head and neck, the relationship between tackling and football-related injuries, and the potential effects of limiting or delaying tackling on injury risk.

    Achilles tendon is the tendon connecting the heel with the calf muscles. Tendo-achilles injury (TAI) in players is common in games. The frequency of TAI is unknown and aetiology is controversial: The present descriptive cross-sectional study was done to determine the prevalence of TAI and associated factors contributing to it in football, cricket and badminton. From January to June 2012, male players (n = 131), age -17-35 years, were selected by purposive sampling technique from renowned sporting clubs at Dhaka, Bangladesh. TAI was diagnosed through structured questionnaire and interviewing the respondents. The analysis by Statistical Package for Social Sciences (SPSS) programme revealed that 11.5% players suffered from TAI, i.e. prevalence was 115 per 1000 respondents. Most injuries (70/131; 53.4%) occurred in the playground and (59/131; 45.3%) happened in practice field. Injuries among the players of third division were higher, i.e. about 36% (p = 0.000). TAI was significantly dependent on occupation (p = 0.046), BMI (p = 0.008), divisional status (p = 0.023), game type (p = 0.043), ground condition (p = 0.05) and injury severity (p = 0.000). The injured players referred for treatment to the physiotherapist was highest (9/15, i.e. 60%) followed by the physicians (5/15, i.e. 33%) (p = 0.000). The associations of TAI with various factors were discussed suggesting effective measures be taken and treatment, particularly physiotherapy, be given to injured players. However, there is a need of team work with sports medicine specialist also to enable the injured players to continue their professional games.

    Full Text Available The FIFA 11+ is a simple, and easy to implement, sports injury prevention program comprising a warm up of 10 conditioning exercises. The aim of this systematic review was to evaluate the impact of the FIFA 11+ on injury incidence, compliance and cost effectiveness when implemented among football players. MEDLINE, EMBASE and Scopus databases were searched using the search terms “FIFA 11+”, “football”, “soccer”, “injury prevention”, and “The 11”. The titles and abstracts were screened by two independent reviewers and the data were filtered by one reviewer using a standardized extraction form and thereafter checked by another one. The risk of bias and the methodological quality of the studies were evaluated through the PEDro score and Critical Appraisal Skills Programme (CASP. A total of 911 studies were identified, of which 12 met the inclusion criteria of the review. The FIFA 11+ has demonstrated how a simple exercise program completed as part of warm-up can decrease the incidence of injuries in amateur football players. In general, considerable reductions in the number of injured players, ranging between 30% and 70%, have been observed among the teams that implemented the FIFA 11+. In addition, players with high compliance to the FIFA 11+ program had an estimated risk reduction of all injuries by 35% and show significant improvements in components of neuromuscular and motor performance when participating in structured warm-up sessions at least 1.5 times/week. Most studies had high methodological quality and a low risk of bias. Given the large number of people who play football at amateur level and the detrimental impact of sports injuries on a personal and societal level, the FIFA 11+ can be considered as a fundamental tool to minimize the risks of participation in a sport with substantial health benefits.

    The study objective was to describe the types, localizations and severity of injuries among first division Bundesliga football players, and to study the effect of playing position on match and training injury incidence and severity, based on information from the public media. Exposure and injuries data from 1 448 players over 6 consecutive seasons were collected from a media-based register. In total, 3 358 injuries were documented. The incidence rate for match and training injuries was 11.5 per 1 000 match-hours (95% confidence interval [CI]: 10.9-12.2), and 61.4 per 100 player-seasons (95% CI: 58.8-64.1), respectively. Strains (30.3%) and sprains (16.7%) were the major injury types, with the latter causing significantly longer lay-off times than the former. Significant differences between the playing positions were found regarding injury incidence and injury burden (lay-off time per incidence-rate), with wing-defenders sustaining significantly lower incidence-rates of groin injuries compared to forwards (rate ratio: 0.43, 95% CI: 0.17-0.96). Wing-midfielders had the highest incidence-rate and injury burden from match injuries, whereas central-defenders sustained the highest incidence-rate and injury burden from training injuries. There were also significant differences in match availability due to an injury across the playing positions, with midfielders sustaining the highest unavailability rates from a match and training injury. Injury-risk and patterns seem to vary substantially between different playing positions. Identifying positional differences in injury-risk may be of major importance to medical practitioners when considering preventive measures.

    Rugby union football continues to gain in popularity in the United States. Both men's and women's clubs have been established at several colleges and universities. There has been substantial growth in the number of high school rugby football clubs in recent years. With the increase in numbers of young participants in this sport, it is important that great efforts be mounted to attempt to control the injury rates and severity of injuries in rugby football. Players and coaches must be knowledgeable of the rules of the game, and referees must strictly enforce these rules. Physicians and dentists should be involved in educating parents, coaches, players, and school officials about the inherent risks of injury and the means for injury prevention. Medical personnel must also be instrumental in educating players about alcohol abuse/addiction. Rugby players should be encouraged to use the limited protective gear that is allowed: wraps, tape, joint sleeves, scrum caps, and facial grease to prevent lacerations. Mouthguards are strongly recommended at any level of play and should be mandated. The use of helmets, face masks, and shoulder pads has been suggested by some authors. Such rule changes could actually increase injury rates and severity, because this equipment could be used as weapons as they are in American football. It is recommended that rugby clubs purchase or build equipment to practice scrummage skills. Coaches should be experienced and attend clinics or complete video courses on medical emergencies and safe techniques of the game. Injury frequency and severity can be decreased by adequate preseason training and conditioning, proper tackling and falling techniques, strengthening of neck muscles, and allowing only experienced, fit athletes to play in the front row. Medical surveillance must be improved at matches and, ideally, at practice sessions. At present, it is common for no emergency medical personnel or physicians to be present at matches in the United

    American football has become one of the most popular sports in the United States. Despite the millions of players at all levels of competition who gain the physical, social, and psychological rewards that football provides, many interested stakeholders continue to ask, "Is football safe?" Although there are only approximately 1,700 players on National Football League (NFL) rosters, the injuries they sustain have garnered the most attention-and criticism-from the national media. Increased public awareness of the injury potential football possesses has led to an open debate and a major shift in public sentiment over the past 5 years. Although no sport is perfectly safe, the question is whether it can be made relatively safe and if the long-term consequences are worth the risk. This article reviews the methods by which one sports league-the NFL-has used advances in medical technology and injury surveillance to improve the health and safety of its players. PMID:27258045

    Youth football is a popular sport in the United States and has been for some time. There are currently more than 3 million participants in youth football leagues according to USA Football. While the number of participants and overall injuries may be higher in other sports, football has a higher rate of injuries. Most youth sporting events do not have medical personnel on the sidelines in event of an injury or emergency. Therefore it is necessary for youth sports coaches to undergo basic medical training in order to effectively act in these situations. In addition, an argument could be made that appropriate medical personnel should be on the sideline for collision sports at all levels, from youth to professional. This article will discuss issues pertinent to sideline coverage of youth football, including coaching education, sideline personnel, emergency action plans, age and size divisions, tackle versus flag football, and injury prevention.

    Long-term neurological damage as a result of head trauma while playing sports is a major concern for football athletes today. Repetitive concussions have been linked to many neurological disorders. Recently, it has been reported that repetitive subconcussive events can be a significant source of accrued damage. Since football athletes can experience hundreds of subconcussive hits during a single season, it is of utmost importance to understand their effect on brain health in the short and long term. In this study, resting-state functional magnetic resonance imaging (rs-fMRI) was used to study changes in the default mode network (DMN) after repetitive subconcussive mild traumatic brain injury. Twenty-two high school American football athletes, clinically asymptomatic, were scanned using the rs-fMRI for a single season. Baseline scans were acquired before the start of the season, and follow-up scans were obtained during and after the season to track the potential changes in the DMN as a result of experienced trauma. Ten noncollision-sport athletes were scanned over two sessions as controls. Overall, football athletes had significantly different functional connectivity measures than controls for most of the year. The presence of this deviation of football athletes from their healthy peers even before the start of the season suggests a neurological change that has accumulated over the years of playing the sport. Football athletes also demonstrate short-term changes relative to their own baseline at the start of the season. Football athletes exhibited hyperconnectivity in the DMN compared to controls for most of the sessions, which indicates that, despite the absence of symptoms typically associated with concussion, the repetitive trauma accrued produced long-term brain changes compared to their healthy peers.

    Full Text Available The different player positions in rugby union may place varying demands on a reconstructed anterior cruciate ligament (ACL in regards to 'cutting manoeuvres', this in turn may effect performance. In order to investigate sporting performance post reconstruction, a questionnaire was sent to amateur rugby clubs affiliated to the Oxfordshire Rugby Football Union (R.F.U. From the returned questionnaires player positions were placed into categories based on similar 'cutting manoeuvre' demands. Seventy five percent of Individuals playing in the category 1 (low 'cutting manoeuvre' demands at slow running speeds could play a full game with a damaged ACL and post-reconstruction the majority returned to play at a higher level. Fifty percent of ACL injuries occurred on category 2 (high 'cutting manoeuvre' demands at medium running speeds suggesting they may be more prone to ACL injury than other positions. The majority of individuals playing in category 3 (high 'cutting manoeuvre' demands at fast speeds played at a lower level of rugby post reconstruction. Positional demands may influence ACL injury and post reconstruction sporting performance. However, more research is needed

Evidence Acquisition In response to this, research into prevention and management of hamstring injury has increased, but epidemiological data shows no decline in injury and re-injury rates, suggesting that rehabilitation programs and return to play (RTP criteria have to be improved. There continues to be a lack of consensus regarding how to assess performance, recovery and readiness to RTP, following hamstring strain injury. Results The aim of this paper was to propose rehabilitation protocol for hamstring muscle injuries based on current basic science and research knowledge regarding injury demographics and management options. Conclusions Criteria-based (subjective and objective progression through the rehabilitation program will be outlined along with exercises for each phase, from initial injury to RTP.

    The issue of concussion in football is of substantial interest to players, coaches, fans, and physicians. In this article, we review specific cultural hindrances to diagnosis and treatment of concussion in football. We review current trends in management and identify areas for improvement. We also discuss the obligations that physicians, particularly neurosurgeons and neurologists, have toward brain-injured football players and the larger societal role they may play in helping to minimize football-associated brain injury.

    Background: Hamstring strain injuries (HSI) are one of the most common injuries in a wide variety of running-sports, resulting in a considerable loss of competition and training time. One of the most problematic consequences regarding HSI is the recurrence rate and its non-decrease over the past decades, despite increasing evidence. Recent studies also found several maladaptations post-HSI probably due to neuromuscular inhibition and it has been proposed that these adaptations post-injury may...

    Soccer is the most common sport activity worldwide. Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured. For sufficient radiological diagnosis knowledge of the biomechanics of the soccer game and some details about the history of the injury may be of help. To prevent soccer injuries or keep the degree of injury low, special programs had been developed. (orig.) [German] Fussball ist die weltweit am meisten verbreitete Sportart. Der Zuwachs an Fussballspieler(innen) in den letzten beiden Jahrzehnten wird jedoch hauptsaechlich auf das verstaerkte Interesse an weiblichen Spielern zurueckgefuehrt. Das Fussballspiel gilt grundsaetzlich, insbesondere wenn man geringfuegige Verletzungen, die keine therapeutischen Massnahmen notwendig machen, sondern lediglich eine kurzfristige Trainings- oder Spielpause bedingen, als eine relativ sichere Sportart. Auf Grund der Vielzahl an SpielerInnen kommt es allerdings doch zu einer betraechtlichen Anzahl durchaus sehr schwerer Verletzungen. Diese Tatsache stellt ein Problem fuer Spieler und Team dar und mag moeglicherweise auch fuer das soziooekonomische System problematisch werden. Von Verletzungen sind v. a. auf Grund der Natur des Spieles die unteren Extremitaeten betroffen. Zur Durchfuehrung einer suffizienten radiologischen Diagnostik sind Kenntnisse der moeglichen Verletzungsmechanismen und eine Anamneseerhebung von nicht zu unterschaetzendem Wert.

    Full Text Available Abstract Background Despite negative neuroimaging findings many athletes display neurophysiological alterations and post-concussion symptoms that may be attributable to neurometabolic alterations. Methods The present study investigated the effects of sports concussion on brain metabolism using 1H-MR Spectroscopy by comparing a group of 10 non-concussed athletes with a group of 10 concussed athletes of the same age (mean: 22.5 years and education (mean: 16 years within both the acute and chronic post-injury phases. All athletes were scanned 1-6 days post-concussion and again 6-months later in a 3T Siemens MRI. Results Concussed athletes demonstrated neurometabolic impairment in prefrontal and motor (M1 cortices in the acute phase where NAA:Cr levels remained depressed relative to controls. There was some recovery observed in the chronic phase where Glu:Cr levels returned to those of control athletes; however, there was a pathological increase of m-I:Cr levels in M1 that was only present in the chronic phase. Conclusions These results confirm cortical neurometabolic changes in the acute post-concussion phase as well as recovery and continued metabolic abnormalities in the chronic phase. The results indicate that complex pathophysiological processes differ depending on the post-injury phase and the neurometabolite in question.

Participants rated comfort for designated anatomical segments of the lower limb utilizing a seven point Likert scale. The aims of the study were (i to assess the reliability of the LLCI in a competitive football environment (Australian Rules and Rugby League, and (ii to assess whether LLCI measurements were responsive to changes in lower limb comfort over time.Methods and Results: The reliability of the LLCI was observed in two professional football environments: Training Week (mean difference 0.1 point, intra-class correlation coefficient, ICC 0.99 for n = 41 participants; and Match Day (mean difference 0.2 points, ICC 0.97 for n = 22 players. Measurements of lower limb comfort were responsive to changes in comfort over time. Within-player differences were not significant for periods 0–8 hrs (P > 0.05 but, generally, significant for time periods 0–24 hrs (P < 0.05, and significant between 24–96 hrs (P < 0.01. The results indicate that the LLCI was reliable when tested for repeated measures and indicated how the index measures lower limb comfort changes over time.Conclusion: This study shows that the use of a lower limb comfort index, when used in a competitive football environment, is both reliable and responsive to change during both a training week and under match day conditions.Keywords: lower limb comfort, musculoskeletal, football, injury

    Full Text Available Background: There is scant information on the types of musculoskeletal injuries, their causes and injury patterns that are sustained by Australian garrison soldiers (a permanent military post or place where troops are stationed. Rigorous physical training, manually emplacing weapon systems and daily military duties carried out by soldiers of the 16th Air Defence Regiment reflect the types of injuries observed in this study. It defines the injury patterns for trained soldiers and addresses those aspects of injury and mechanism of injury, forming the basis for further research targetted at injury prevention. Purpose: To identify the predominant musculoskeletal injuries sustained by soldiers of the 16th Air Defence Regiment and to explore the relationship between the type of injury and subunit as well as the relationship between type of injury and cause. This is important so that remedial measures can be engaged in an attempt to reduce the incidence of musculoskeletal injury to Australian soldiers, to maintain the regimental fighting strength and deployable status and to reduce the financial burden of rehabilitation and compensation borne by the Australian Defence Force and the Federal Government. Materials and Methods: All patients were trained serving soldiers of the 16th Air Defence Regiment and were referred by the Medical Officer for physiotherapy treatment. On conclusion of a course of treatment, a physiotherapy patient discharge summary (PM 528 was written and it is from these summaries that the demographic data for this study was extracted, which included the type of musculoskeletal injury (diagnosis, cause of that injury and the subunit that the soldier belonged to in the 16th Air Defence Regiment during the years 2008 to 2010. Tests of significance based on the chi-square test statistic were carried out at the 0.05 significance level using Minitab 16 statistical software.

    The present study evaluated the effects of a newly developed injury prevention programme for children's football ("FIFA 11+ Kids") on motor performance in 7-12-year-old children. We stratified 12 football teams (under-9/-11/-13 age categories) into intervention (INT, N = 56 players) and control groups (CON, N = 67). INT conducted the 15-min warm-up programme "FIFA 11+ Kids" twice a week for 10 weeks. CON followed a standard warm-up (sham treatment). Pre- and post-tests were conducted using: single leg stance; Y-balance test; drop and countermovement jump; standing long jump; 20-m sprint; agility run; slalom dribble; and wall volley test. We used magnitude-based inferences and linear mixed-effects models to analyse performance test results. We observed likely beneficial effects favouring INT in Y-balance (right leg; +3.2%; standardised mean difference (SMD) = 0.34; P = 0.58) and agility run (+3.6%; SMD = 0.45; P = 0.008). Possibly beneficial effects were found in Y-balance, drop jump reactive strength index, drop jump height, countermovement jump, standing long jump, slalom dribble and wall volley test. At least possibly beneficial improvements in favour of "FIFA 11+ Kids" were observed in nearly all parameters. Most effects were small, but slight improvements in motor performance may potentially contribute to a reduction of injury risk. PMID:26508531

    This case report illustrates and discusses the non-operative management of a complete anterior cruciate ligament (ACL) injury in an English Premier League football player, his return to play within 8 weeks and problem-free follow-up at 18 months post injury. When non-operative verses surgical ACL reconstruction is considered there are many fundamental gaps in our knowledge and currently, at elite level, there are no cases in cutting sports within the literature to guide these decisions. When the norm is for all professional footballers to be recommended surgery, it will be very challenging when circumstances and patient autonomy dictate a conservative approach, where prognosis, end points and risk are unclear and assumed to be high. This case challenges current dogma and provides a starting point for much needed debate about best practice, treatment options, research direction and not just at the elite level of sport.

    A lack of available injury data on community sports participants has hampered the development of informed preventive strategies for the broad-base of sports participation. In community sports settings, sports trainers or first-aiders are well-placed to carry out injury surveillance, but few studies have evaluated their ability to do so. The aim of this study was to investigate the reporting rate and completeness of sports trainers' injury records and agreement between sports trainers' and players' reports of injury in community Australian football. Throughout the football season, one sports trainer from each of four clubs recorded players' injuries. To validate these data, we collected self-reported injury data from players via short message service (SMS). In total, 210 discrete injuries were recorded for 139 players, 21% by sports trainers only, 59% by players via SMS only, and 21% by both. Completeness of injury records ranged from 95% to 100%. Agreement between sports trainers and players ranged from K = 0.32 (95% confidence interval: 0.27, 0.37) for date of return to football to K = 1.00 for activity when injured. Injury data collected by sports trainers may be of adequate quality for providing an understanding of the profile of injuries. However, data are likely to underestimate injury rates and should be interpreted with caution.

    Injuries to the hamstring muscles are common in athletes. Track and field, Australian football, American football and soccer are examples of sports where hamstring injuries are the most common. The purpose of this study was to investigate whether there is a correlation between a hamstring injury prognosis and its characteristics of imaging parameters. The literature search was performed in the databases PubMed and CINAHL, and eleven articles were included. Seven out of the 11 articles showed a correlation between the size of the hamstring injury and length of time required before returning to sports. Different authors have reported contrasting results about length of time required before returning to sports due to location of injury within specific muscle. Majority of the articles found hamstring strain correlated to an extended amount of time required before returning to sports. PMID:27419106

    <正>Hamstring strains are one of most common sports injuries.The purpose of this literature review is to summarize studies on hamstring strain injury rate,mechanism,and risk factors in the last several decades with a focus on the prevention and rehabilitation of this injury.Hamstring injury commonly occurs in sporting events in which high speed sprinting and kicking are frequently performed,such as Australian football. English rugby,American football,and soccer.Basic science studies have demonstrated that a muscle strain injury occurs due to excessive strain in eccentric contraction instead of force,and that elongation speed and duration of activation before eccentric contraction affect the severity of the injury.Hamstring strain injury is likely to occur during the late swing phase and late stance phase of sprint running.Shortened optimum muscle length,lack of muscle flexibility,strength imbalance,insufficient warm-up,fatigue,lower back injury,poor lumbar posture,and increased muscle neural tension have been identified as modifiable risk factors while muscle compositions,age,race,and previous injuries are non-modifiable risk factors.The theoretical basis of some of these risk factors,however,is lacking,and the results of clinical studies on these risk factors are inconsistent.Future studies are needed to establish the cause-and-effect relationships between those proposed risk factors and the injury.

    This article compares the epidemiological profile of injury-related hospitalized morbidity of international tourists in New South Wales (NSW) with the hospitalized injury profile of NSW residents. Injury-related hospitalizations were identified from the NSW Admitted Patients Data Collection during 1 July 2000 to 30 June 2009. Injuries were identified using a principal diagnosis code of injury (ie, ICD-10-AM range S00-T98) and the presence of an external cause code (ie, ICD-10-AM range V00-Y98). Overseas tourists were more likely to be hospitalized for an injury following air and water transport, near-drowning, and pedestrian-related injuries. Sport or leisure-related activities were the most common activity conducted at the time of the incident. International tourists are at a higher risk of experiencing injuries particularly following recreational pursuits, while as a pedestrian, in vehicle crashes for older age groups, as a result of interpersonal violence for young males, and following a poisoning or cut/pierce injury for young females. Prevention measures should be undertaken to limit the incidence of injury among international tourists, particularly during active recreational activities and while using the roadways.

    Laudner, Kevin G

    2012-03-01

    Injuries stemming from shoulder instability are very common among athletes participating in contact sports, such as football. Previous research has shown that increased laxity negatively affects the function of the sensorimotor system potentially leading to a pathological cycle of shoulder dysfunction. Currently, there are no data detailing such effects among football players. Therefore, the purpose of this study was to examine the differences in upper extremity sensorimotor control among football players compared with that of a control group. Forty-five collegiate football players and 70 male control subjects with no previous experience in contact sports participated. All the subjects had no recent history of upper extremity injury. Each subject performed three 30-second upper extremity balance trials on each arm. The balance trials were conducted in a single-arm push-up position with the test arm in the center of a force platform and the subjects' feet on a labile device. The trials were averaged, and the differences in radial area deviation between groups were analyzed using separate 1-way analyses of variance (p football players showed significantly more radial area deviation of the dominant (0.41 ± 1.23 cm2, p = 0.02) and nondominant arms (0.47 ± 1.63 cm2, p = 0.03) when compared with the control group. These results suggest that football players may have decreased sensorimotor control of the upper extremity compared with individuals with no contact sport experience. The decreased upper extremity sensorimotor control among the football players may be because of the frequent impacts accumulated during football participation. Football players may benefit from exercises that target the sensorimotor system. These findings may also be beneficial in the evaluation and treatment of various upper extremity injuries among football players.

  16. Hip adductors' strength, flexibility, and injury risk.

    Hrysomallis, Con

    2009-08-01

    The hip adductor muscle group plays an important role in both movement and stability at the hip joint in many athletic pursuits. Injury to this muscle group has been reported in a number of sports, among them, ice hockey, soccer, Australian football, and swimming. The identification of muscle characteristics that predispose a muscle to injury is an important step in developing conditioning programs to reduce injury risk. Muscle strength and range of motion are 2 parameters that may influence injury risk. The aim of this review was to examine the relationship between hip adductors' strength, flexibility, and injury risk. Strength testing has involved isokinetic or hand-held dynamometry. Flexibility has usually been assessed by goniometry during maximal hip abduction. An association has been reported between adductor strength deficits and injury for ice hockey players. Low adductor flexibility has also been identified as a risk factor for injury in soccer players. An intervention program that strengthened the hip adductors had some success in reducing injury risk for ice hockey players. There is some low- to moderate-level evidence from cohort studies to suggest that flexibility and strength are related to injury risk in particular sports and that an intervention program may be effective in reducing injury risk. Higher level evidence from randomized controlled trials is required to firmly establish the link between hip adductor flexibility, strength, and injury. PMID:19620912

Inspired by Edgar Schein’s framework of culture, the Brazilian...... and Italian national team football cultures were examined. The basis of the analysis was both document and video analysis. The documents were mostly research studies and popular books on the national football cultures, while the video analysis included all matches including Italy and Brazil from the World Cup...... in 2010 and 2014. The cultural analysis showed some coherence between the national football cultures and the national teams, which suggested a national dialect with the language of the game. Each national dialect seemed to be based on different basic assumptions and to some extent specific symbolic...

    Full Text Available OBJECTIVE: Develop an epidemiological study of injuries occurred among male professional football players during the Copa America 2011, held in Argentina. METHODS: We conducted a retrospective study of injuries sustained during the 43rd edition of the Copa America football in Argentina, in 2011. The lesions were evaluated by the medical department of the selections and reported to the CONMEBOL. The data were compiled and reported in accordance with rules established by the FIFA Medical Assessment and Research Centre (F-MARC in 2005. RESULTS: There was a higher prevalence of lesions in the lower limbs. Thighs and knees were the most affected segments. The most frequent diagnoses were muscle injuries. The injuries were mostly minor degrees of severity and there was little difference in the prevalence of lesions according to the stages of the match, with slight predominance in the final 15 minutes. The incidence of lesions per 1,000 game hours was similar to the average found in the literature. CONCLUSIONS: The results obtained allowed us to outline a profile of the prevalence, distribution per body segment, minute in which occurred and severity of injuries in professional football players of participating teams in the Copa America 2011 in Argentina. The extreme rigor of referees may be partly attributed to the highly competitive nature of international tournaments. However, this results cannot be considered definitive because of the need to be compared to other epidemiological studies with same design using similar concepts and criteria.

    Background: Although a recognized and discussed injury, chondral rib fractures in professional American football have not been previously reported in the literature. There currently exists no consensus on how to identify and treat these injuries or the expected return to play for the athlete. Purpose: To present 2 cases of chondral rib injuries in the National Football League (NFL) and discuss the current practice patterns for management of these injuries among the NFL team physicians. Study Design: Case series; Level of evidence, 4. Methods: Two cases of NFL players with chondral rib injuries are presented. A survey regarding work-up and treatment of these injuries was completed by team physicians at the 2014 NFL Combine. Our experience in identifying and treating these injuries is presented in conjunction with a survey of NFL team physicians’ experiences. Results: Two cases of rib chondral injuries were diagnosed by computed tomography (CT) and treated with rest and protective splinting. Return to play was 2 to 4 weeks. NFL Combine survey results show that NFL team physicians see a mean of 4 costal cartilage injuries per 5-year period, or approximately 1 case per year per team. Seventy percent of team physicians use CT scanning and 43% use magnetic resonance imaging for diagnosis of these injuries. An anesthetic block is used acutely in 57% and only electively in subsequent games by 39%. Conclusion: A high index of suspicion is necessary to diagnose chondral rib injuries in American football. CT scan is most commonly used to confirm diagnosis. Return to play can take up to 2 to 4 weeks with a protective device, although anesthetic blocks can be used to potentially expedite return. Clinical Relevance: Chondral rib injuries are common among NFL football players, while there is no literature to support proper diagnosis and treatment of these injuries or expected duration of recovery. These injuries are likely common in other contact sports and levels of

  1. The Anthropology of Football

    Full Text Available Anthropological interest in football has been on the rise since the beginning of the century, which can be attested to by the rising number of studies, papers, collective publications and scientific conferences on the topic. Seeing as anthropology is no longer the study of the culturally bizarre and exotic, it is clear that the first anthropological studies of football as a cultural phenomenon are linked to those environments in which football figures as an important cultural trait, which is the reason why this sub discipline thrived in Europe or in places where football was treated as an esoteric phenomenon and where there as a longer tradition of anthropological study of native cultures. From the first analogies between the game of football and its rules with rituals of so called primitive cultures, the anthropological study of football developed into a relatively encompassing approach which includes interest in all the actors who establish the game as a public, cultural good – players, experts, supporters, journalists, organizers etc. – as well as its various cultural manifestations, in the form of a tool for the construction of identity and cultural symbol, a leisure activity with ties to economy, to a specific apotheosis of the concepts of globalization and commodification of culture. Anthropological studies of football are present in Serbia as well, and their subject matter corresponds to the role and position held by football, as a cultural artefact, in Serbian society and other countries in the region.

    There has been increasing concern, particularly in the US, about potential long-term neurological deterioration syndromes seen in the US football players. Recurrent concussions are a potential area of concern. The authors of this paper have used data bases from three levels of amateur US football to identify the rate and risk of concussion injury in both football games and practice at the youth, high school, and college levels. This information is very important initial data around concussion rates at these levels.

Its major strengths are that it has wide usage, has codes specific to sports medicine and that it is free to use. Literature searches and stakeholder consultations were made to assess the uptake of OSICS and to develop new versions. OSICS was commonly used in the sports of football (soccer, Australian football, rugby union, cricket and tennis. It is referenced in international papers in three sports and used in four commercially available computerised injury management systems. Suggested injury categories for the major sports are presented. New versions OSICS 9 (three digit codes and OSICS 10.1 (four digit codes are presented. OSICS is a potentially helpful component of a comprehensive sports injury surveillance system, but many other components are required. Choices made in developing these components should ideally be agreed upon by groups of researchers in consensus statements.Keywords: sports injury classification, epidemiology, surveillance, coding

    Full Text Available Abstract Background There is a paucity of epidemiological data on neck injury in amateur rugby union populations. The objective of this study was to determine the incidence, severity, aetiology and type of neck injury in Australian men's amateur rugby union. Methods Data was collected from a cohort of 262 participants from two Australian amateur men's rugby union clubs via a prospective cohort study design. A modified version of the Rugby Union Injury Report Form for Games and Training was used by the clubs physiotherapist or chiropractor in data collection. Results The participants sustained 90 (eight recurrent neck injuries. Exposure time was calculated at 31143.8 hours of play (12863.8 hours of match time and 18280 hours of training. Incidence of neck injury was 2.9 injuries/1000 player-hours (95%CI: 2.3, 3.6. As a consequence 69.3% neck injuries were minor, 17% mild, 6.8% moderate and 6.8% severe. Neck compression was the most frequent aetiology and was weakly associated with severity. Cervical facet injury was the most frequent neck injury type. Conclusions This is the first prospective cohort study in an amateur men's rugby union population since the inception of professionalism that presents injury rate, severity, aetiology and injury type data for neck injury. Current epidemiological data should be sought when evaluating the risks associated with rugby union football.

    Full Text Available Abstract Background Football is officially the most popular sport in the world. In the UK, 10% of the adult population play football at least once a year. Despite this, there are few papers in the literature on tibial diaphyseal fractures in this sporting group. In addition, conflicting views on the nature of this injury exist. The purpose of this paper is to compare our experience of tibial shaft football fractures with the little available literature and identify any similarities and differences. Methods and Results A retrospective study of all tibial football fractures that presented to a teaching hospital was undertaken over a 5 year period from 1997 to 2001. There were 244 tibial fractures treated. 24 (9.8% of these were football related. All patients were male with a mean age of 23 years (range 15 to 29 and shin guards were worn in 95.8% of cases. 11/24 (45.8% were treated conservatively, 11/24 (45.8% by Grosse Kemp intramedullary nail and 2/24 (8.3% with plating. A difference in union times was noted, conservative 19 weeks compared to operative group 23.9 weeks (p Conclusion Our series compared similarly with the few reports available in the literature. However, a striking finding noted by the authors was a drop in the incidence of tibial shaft football fractures. It is likely that this is a reflection of recent compulsory FIFA regulations on shinguards as well as improvements in the design over the past decade since its introduction.

    We investigate the dynamics of football matches. Our goal is to characterize statistically the temporal sequence of ball movements in this collective sport game, searching for traits of complex behavior. Data were collected over a variety of matches in South American, European and World championships throughout 2005 and 2006. We show that the statistics of ball touches presents power-law tails and can be described by $q$-gamma distributions. To explain such behavior we propose a model that provides information on the characteristics of football dynamics. Furthermore, we discuss the statistics of duration of out-of-play intervals, not directly related to the previous scenario.

    Full Text Available Abstract Background This paper describes a case of C7 radiculopathy in a professional rugby league player after repeated cervical spine trauma. The report outlines the management of the patient following an acute cervical hyperflexion injury with chiropractic manipulation and soft tissue therapies. It also presents a change in approach to include distractive techniques on presentation of a neurological deficit following re-injury. The clinical outcomes, while good, were very dependent upon the athlete restricting himself from further trauma during games, which is a challenge for a professional athlete. Case presentation A 30-year old male front row Australian rugby league player presented complaining of neck pain after a hyperflexion and compressive injury during a game. Repeated trauma over a four month period resulted in radicular pain. Radiographs revealed decreased disc height at the C5-C6 and C6-C7 levels and mild calcification within the anterior longitudinal ligament at the C6-C7 level. MRI revealed a right postero-lateral disc protrusion at the C6-C7 level causing a C7 nerve root compression. Conclusion Recommendations from the available literature at the present time suggest that conservative management of cervical discogenic pain and disc protrusion, including chiropractic manipulation and ancillary therapies, can be successful in the absence of progressive neurological deficit. The current case highlights the initial successful management of a football athlete, and the later unsuccessful management. This case highlights the issues involvement in the management of a collision sport athlete with a serious neck injury.

    Hampshire, Adam; MacDonald, Alex; Owen, Adrian M.

    2013-10-01

    Recent research has raised concerns about the long-term neurological consequences of repetitive concussive and sub-concussive injuries in professional players of American Football. Despite this interest, the neural and psychological status of retired players remains unknown. Here, we evaluated the performances and brain activation patterns of retired National Football League players (NFL alumni) relative to controls using an fMRI-optimised neuropsychological test of executive function. Behaviourally, the NFL alumni showed only modest performance deficits on the executive task. By contrast, they showed pronounced hyperactivation and hypoconnectivity of the dorsolateral frontal and frontopolar cortices. Critically, abnormal frontal-lobe function was correlated with the number of times that NFL alumni reported having been removed from play after head injury and was evident in individual players. These results support the hypothesis that NFL alumni have a heightened probability of developing executive dysfunction and suggest that fMRI provides the most sensitive biomarker of the underlying neural abnormality.

    Like other traditional Chinese sports, the ancient Chinese football, which used to be called “cuju”, has some differences from several sports in western countries concerning cultural and hamanist purport as well as metal aspiration, although it was similar with modern football to some extent, such as a leather-made ball with a bladder, rectangle sports ground, referee, goal and certain competitiveness. The author tries to talk about such difference in cultural and humanist purport as well as mental aspiration by making a comparison between “cuju” and modern football.

    2016-02-01

    Concussion in football athletes is certainly more prevalent and has potentially serious outcomes. With current concerns and increasing return-to-play issues, additional assessment focus is needed. Division 1 college football athletes, from 18 to 20.9 years (n = 177; age, 19.7 ± 1.2 years; height, 182.3 ± 4.5 cm; weight, 97.3 ± 10.6 kg), before fall practice, over a period of 3 years, underwent baseline postural stability testing (sensory organization test [SOT], NeuroCom). Individuals, who were diagnosed with a concussion (headache, dizziness, fatigue, confusion, or loss of consciousness) during practice or actual competition (n = 15; age, 18.9 ± 0.9 years; height, 181.8 ± 2.5 cm; weight, 86.6 ± 3.6 kg), underwent serial evaluation after injury and 24 hours after concussion. As soon as the player was considered asymptomatic, the test was completed on the first and 14th day. A control group of noninjured male athletes (n = 15; age, 19.1 ± 0.4 years; height, 178.2 ± 3.2 cm; weight, 78.6 ± 2.1 kg) were tested for the same time frame. This particular study was only one part of the total evaluation conducted for the concussed athlete's return to play. Results indicated that the concussion group had a statistically significant (p = 0.037) change from their baseline SOT score and the control group (p = 0.025). This change remained significant until day 14 of posttesting. These data indicate that the SOT, when available, may be a positive additional assessment of concussed college-aged football players. Professionals, when dealing with concussion in competitive sports, do need to continue to work together, but awareness of SOT assessments may also contribute to the return-to-play decisions.

    The high school sports of wrestling, gymnastics, ice hockey, baseball, track, and cheerleading should receive closer attention to prevent injury. Safer equipment and sport-specific conditioning should be provided and injuries strictly monitored. Greater attention must also be paid to swimming and diving techniques, and continued observation is needed for heat stroke and heat intolerance in sports such as football, wrestling, basketball, track and field, and cross-country. An increased awareness of commotio cordis in sports other than baseball should include ice hockey, football, track field events, and lacrosse. American football because of the sheer numbers and associated catastrophic injury potential must continue to be monitored at the highest medical levels! PMID:12119866

    2011-02-01

    Full Text Available Abstract Background Collecting population data on sensitive issues such as non-suicidal self-injury (NSSI is problematic. Case note audits or hospital/clinic based presentations only record severe cases and do not distinguish between suicidal and non-suicidal intent. Community surveys have largely been limited to school and university students, resulting in little much needed population-based data on NSSI. Collecting these data via a large scale population survey presents challenges to survey methodologists. This paper addresses the methodological issues associated with collecting this type of data via CATI. Methods An Australia-wide population survey was funded by the Australian Government to determine prevalence estimates of NSSI and associations, predictors, relationships to suicide attempts and suicide ideation, and outcomes. Computer assisted telephone interviewing (CATI on a random sample of the Australian population aged 10+ years of age from randomly selected households, was undertaken. Results Overall, from 31,216 eligible households, 12,006 interviews were undertaken (response rate 38.5%. The 4-week prevalence of NSSI was 1.1% (95% ci 0.9-1.3% and lifetime prevalence was 8.1% (95% ci 7.6-8.6. Methodological concerns and challenges in regard to collection of these data included extensive interviewer training and post interview counselling. Ethical considerations, especially with children as young as 10 years of age being asked sensitive questions, were addressed prior to data collection. The solution required a large amount of information to be sent to each selected household prior to the telephone interview which contributed to a lower than expected response rate. Non-coverage error caused by the population of interest being highly mobile, homeless or institutionalised was also a suspected issue in this low prevalence condition. In many circumstances the numbers missing from the sampling frame are small enough to not cause worry

    1991-12-01

    The present study conducted dietary surveys of four groups of Australian male athletes: triathletes, marathon runners, Australian Rules football players, and Olympic weightlifters. Their training diets were assessed via a 7-day food record from which mean daily intakes of energy, macronutrients, and key micronutrients were estimated. The data were compared between groups as well as to recommendations in the literature for athlete nutrition. Results showed major differences between groups. The contribution of carbohydrate to total energy intake was greater for triathletes and marathon runners than for the other two groups. There was no difference between all four groups in the total amount of fat consumed, yet its contribution to total energy intake was significantly lower for triathletes and marathon runners. The football players and weightlifters consumed a similar fat:energy ratio as the typical Australian diet. Furthermore, the micronutrient density of the football players' diets was significantly lower than that of the other groups. PMID:1844570

  7. External foam layers to football helmets reduce head impact severity.

    Science.gov (United States)

    Nakatsuka, Austin S; Yamamoto, Loren G

    2014-08-01

    Current American football helmet design has a rigid exterior with a padded interior. Softening the hard external layer of the helmet may reduce the impact potential of the helmet, providing extra head protection and reducing its use as an offensive device. The objective of this study is to measure the impact reduction potential provided by external foam. We obtained a football helmet with built-in accelerometer-based sensors, placed it on a boxing mannequin and struck it with a weighted swinging pendulum helmet to mimic the forces sustained during a helmet-to-helmet strike. We then applied layers of 1.3 cm thick polyolefin foam to the exterior surface of the helmets and repeated the process. All impact severity measures were significantly reduced with the application of the external foam. These results support the hypothesis that adding a soft exterior layer reduces the force of impact which may be applicable to the football field. Redesigning football helmets could reduce the injury potential of the sport.

    Previous studies report that cavum septum pellucidum (CSP) is frequent among athletes with a history of repeated traumatic brain injury (TBI), such as boxers. Few studies of CSP in athletes, however, have assessed detailed features of the septum pellucidum in a case-control fashion. This is important because prevalence of CSP in the general population varies widely (2% to 85%) between studies. Further, rates of CSP among American pro-football players have not been described previously. We sought to characterize MRI features of the septum pellucidum in a series of retired pro-football players with a history of repeated concussive/subconcussive head traumas compared with controls. We retrospectively assessed retired American pro-football players presenting to our memory clinic with cognitive/behavioral symptoms in whom structural MRI was available with slice thickness ≤2 mm (n=17). Each player was matched to a memory clinic control patient with no history of TBI. Scans were interpreted by raters blinded to clinical information and TBI/football history, who measured CSP grade (0-absent, 1-equivocal, 2-mild, 3-moderate, 4-severe) and length according to a standard protocol. Sixteen of 17 (94%) players had a CSP graded ≥2 compared with 3 of 17 (18%) controls. CSP was significantly higher grade (pfootball players compared with patients without a history of TBI.

  11. SUITABILITY OF FIFA'S "THE 11" TRAINING PROGRAMME FOR YOUNG FOOTBALL PLAYERS - IMPACT ON PHYSICAL PERFORMANCE

    Directory of Open Access Journals (Sweden)

    Dejan Kuzmic

    2008-09-01

    Full Text Available There is a paucity of evidence regarding the use of injury prevention programmes for preadolescents participating in sport. "The 11" injury prevention programme was developed by FIFA's medical research centre (F-MARC to help reduce the risk of injury in football players aged 14 years and over. The aim of this study was to determine the suitability and effectiveness of "The 11" for younger football players. Twenty-four [12 experimental (EXP, 12 control (CON] young football players (age 10.4 ± 1.4 yr participated. The EXP group followed "The 11" training programme 5 days per week, for 6 weeks, completing all but one of the 10 exercises. Prior to, and after the intervention, both EXP and CON groups performed a battery of football-specific physical tests. Changes in performance scores within each group were compared using independent t-tests (p ? 0.05. Feedback was also gathered on the young players' perceptions of "The 11". No injuries occurred during the study in either group. Compliance to the intervention was 72%. Measures of leg power (3 step jump and counter-movement jump increased significantly (3.4 and 6.0% respectively, p < 0.05. Speed over 20 m improved by 2% (p < 0.05. Most players considered "The 11" beneficial but not enjoyable in the prescribed format. Given the observed improvements in the physical abilities and the perceived benefits of "The 11", it would appear that a modified version of the programme is appropriate and should be included in the training of young football players, for both physical development and potential injury prevention purposes, as well as to promote fair play. To further engage young football players in such a programme, some modification to "The 11" should be considered

  12. Women's football: Player characteristics and demands of the game

    2014-12-01

    Full Text Available The number of scientific investigations on women's football specific to the topics of player characteristics and demands of the game has considerably increased in recent years due to the increased popularity of the women's game worldwide, although they are not yet as numerous as in the case of men's football. To date, only two scientific publications have attempted to review the main findings of studies published in this area. However, one of them was published about 20 years ago, when women's football was still in its infancy and there were only a few studies to report on. The other review was more recent. Nonetheless, its main focus was on the game and training demands of senior elite female players. Thus, information on female footballers of lower competitive levels and younger age groups was not included. Consequently, an updated review is needed in this area. The present article therefore aims to provide an overview of a series of studies that have been published so far on the specific characteristics of female football players and the demands of match-play. Mean values reported in the literature for age (12–27 years, body height (155–174 cm, body mass (48–72 kg, percent body fat (13%–29%, maximal oxygen uptake (45.1–55.5 mL/kg/min, Yo-Yo Intermittent Recovery Test Level 1 (780–1379 m, maximum heart rate (189–202 bpm, 30 m sprint times (4.34–4.96 s, and counter-movement jump or vertical jump (28–50 cm vary mostly according to the players' competitive level and positional role. There are also some special considerations that coaches and other practitioners should be aware of when working with female athletes such as the menstrual cycle, potential pregnancy and lactation, common injury risks (particularly knee and head injuries and health concerns (e.g., female athlete triad, iron deficiency, and anemia that may affect players' football performance, health or return to play.

    Full Text Available The development of professional sport leagues, including football, also referred to as ‘soccer’ in some environments and in the media, is an occurring phenomenon in different nations, where interest and consumption of sport appear to be growing. Football’s establishment in the form of a professional league may however pose a dilemma to professional club marketers in the form of misunderstandings or confusion among consumers, particularly where there are more professional sports that have been traditionally known as “football”. This study investigates both the level of association with and consumption of professional football among residents in a large Australian city. An online questionnaire gathered both quantitative and qualitative data from 695 respondents. The findings illustrate the potential for ‘brand confusion’ when new leagues and teams enter the domestic and international sport marketplace. For instance, almost 30% of respondents associated football with at least one more sport, with no one sport positioning its form of football as exclusive and different from the others. The overall findings underline the need for sport marketers to increase their educational efforts to differentiate their product, their brand, and ultimately their form of football among professional sport consumers.

    Of all sports, football accounts for the highest incidence of concussion in the US due to the large number of athletes participating and the nature of the sport. While there is general agreement that concussion incidence can be reduced through rule changes and teaching proper tackling technique, there remains debate as to whether helmet design may also reduce the incidence of concussion. A retrospective analysis was performed of head impact data collected from 1833 collegiate football players who were instrumented with helmet-mounted accelerometer arrays for games and practices. Data were collected between 2005 and 2010 from 8 collegiate football teams: Virginia Tech, University of North Carolina, University of Oklahoma, Dartmouth College, Brown University, University of Minnesota, Indiana University, and University of Illinois. Concussion rates were compared between players wearing Riddell VSR4 and Riddell Revolution helmets while controlling for the head impact exposure of each player. A total of 1,281,444 head impacts were recorded, from which 64 concussions were diagnosed. The relative risk of sustaining a concussion in a Revolution helmet compared with a VSR4 helmet was 46.1% (95% CI 28.1%-75.8%). When controlling for each player's exposure to head impact, a significant difference was found between concussion rates for players in VSR4 and Revolution helmets (χ(2) = 4.68, p = 0.0305). This study illustrates that differences in the ability to reduce concussion risk exist between helmet models in football. Although helmet design may never prevent all concussions from occurring in football, evidence illustrates that it can reduce the incidence of this injury.

  16. English professional football players concussion knowledge and attitude

    2016-01-01

    Background: Concussions are a common pathology in football and multiple misconceptions exist amongst the players and managers. To address these misconceptions, and potentially reduce concussion associated sequela, effective educational interventions need to be developed. However, the current knowledge and attitude status must be ascertained to appropriately develop these interventions. The purpose of this study was to assess the concussion knowledge and attitude of English professional footballers. Methods: Twenty-six participants from one English Football League Championship club completed the study. A mixed methods approach included the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) and a semi-structured interview. The RoCKAS contains separate knowledge (0–25) and attitude (15–75) scores and was followed by a semi-structured interview consisting of concussion knowledge, attitude, and behavior related questions. Results: The mean score on the RoCKAS knowledge was 16.4 ± 2.9 (range 11–22) and the attitude score was 59.6 ± 8.5 (range 41–71). The interview responses identified inconsistencies between the RoCKAS and the intended behaviors, endorsing multiple concussion misconceptions, and revealed barriers to concussion reporting. Conclusion: The results of this study suggest that Championship Level English footballers have moderate concussion knowledge, safe attitudes, and good concussion symptom recognition when assessed with pen and paper questionnaires. However, within the semi-structured interview many respondents reported unsafe concussion behaviors despite accurately identifying the potential risks. Further, multiple barriers to concussion reporting were identified which included perceived severity of the injury, game situations, and the substitution rule. These findings can help form the foundation of educational interventions to potentially improve concussion reporting behaviors amongst professional footballers.

    Here it is, mid-August, and I don't have my syllabus (or all my plans) together for the fall semester that will begin in a couple of weeks. I leave for the ACS meeting in a day and a half. There are so many things to do. Entropy reigns! (Well, only figuratively. See the papers on pages 1382-1397.) Will I get it all together before that big first day of classes? At this time of year I always have great plans, but also I wonder whether I am Charlie Brownthe eternal optimist, ready to try to kick that football one more time. I know I could score a field goal if only the football weren't pulled away at the last millisecond. But it seems invariably to be pulled away. Or maybe I just don't connect with it properly. Why do I keep kicking that football? What is it about a new school year that gets me psyched up and excited? Teaching (that is, devising and implementing environments and experiences that help people learn) is a challenge, largely because we don't really know that much about how to do it effectively. It's so easy for that football to slither away, never having gotten off the ground. That's one of the things that make teaching interesting and exciting. There are so many ideas to try, and it's fun to see whether they will work. Both successes and failures suggest additional new approaches. Teaching science, like science itself, seems always to produce more questions than answers. For those of us who enjoy experiments, it is an ideal profession. Another reason to get fired up is that a new school year offers opportunities to work with such wonderful people. Whether courses are successful depends on teachers, students, and interactions among them. Every fall there are new groups of students, providing teachers with new opportunities, challenges, experiences, and even friendships. Every fall we teachers have new ideas about both content and pedagogy that spur us to greater efforts and thereby help to develop our students' intellects and abilities. Even more

Taking tablets the size of which sunk the Belgrano. Finding time for physiotherapy, eating the right meals, playing on my Playstation. Depression has got through on previous occasions, but not for long, and it has never resulted in anything more than a 'wake up and smell the coffee' call from myself. Having CF is no ball game (otherwise it would be called football or something!), but I have had a lot of fun and will continue to do so for however long.

  20. Sporting Chance: Indigenous Participation in Australian Sport History

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available For many non-Indigenous Australians the only time they have any engagement with Indigenous peoples, history or issues is through watching sport on television or being at a football match at the MCG. This general myopia and indifference by settler Australians with Indigenous Australians manifests itself in many ways but perhaps most obscenely in the simple fact that Indigenous Australians die nearly 20 years younger than the rest of Australias citizens. Many non-Indigenous Australians do not know this. Sport in many ways has offered Indigenous Australians a platform from which to begin the slow, hard process for social justice and equity to be actualised. This paper will discuss the participation of Indigenous Australians in sport and show how sport has enabled Indigenous Australians to create a space so that they can speak out against the injustices they have experienced and to further improve on relations going into the future. The central contention is that through sport all Australians can begin a process of engaging with Indigenous history as a means to improve race relations between the two groups.

  1. Implementing evidence-based recommended practices for the management of patients with mild traumatic brain injuries in Australian emergency care departments: study protocol for a cluster randomised controlled trial

    Science.gov (United States)

    2014-01-01

    Background Mild head injuries commonly present to emergency departments. The challenges facing clinicians in emergency departments include identifying which patients have traumatic brain injury, and which patients can safely be sent home. Traumatic brain injuries may exist with subtle symptoms or signs, but can still lead to adverse outcomes. Despite the existence of several high quality clinical practice guidelines, internationally and in Australia, research shows inconsistent implementation of these recommendations. The aim of this trial is to test the effectiveness of a targeted, theory- and evidence-informed implementation intervention to increase the uptake of three key clinical recommendations regarding the emergency department management of adult patients (18 years of age or older) who present following mild head injuries (concussion), compared with passive dissemination of these recommendations. The primary objective is to establish whether the intervention is effective in increasing the percentage of patients for which appropriate post-traumatic amnesia screening is performed. Methods/design The design of this study is a cluster randomised trial. We aim to include 34 Australian 24-hour emergency departments, which will be randomised to an intervention or control group. Control group departments will receive a copy of the most recent Australian evidence-based clinical practice guideline on the acute management of patients with mild head injuries. The intervention group will receive an implementation intervention based on an analysis of influencing factors, which include local stakeholder meetings, identification of nursing and medical opinion leaders in each site, a train-the-trainer day and standardised education and interactive workshops delivered by the opinion leaders during a 3 month period of time. Clinical practice outcomes will be collected retrospectively from medical records by independent chart auditors over the 2 month period following

    @@ Footballer' s ankle is anterior bony spur or anterior impingement symptom of the ankle with anterior ankle pain, limited and painful dorsiflexion. The cause is commonly seen in athletes and dancers, and is probably due to repetitive minor trauma. The condition was firstly described by Morris;1 McMurray2 reported good results from excision of the spurs, naming it footballer's ankle. Opening resection of osteophytes of the anterior tibial and superior talar is an effective treatment for anterior impingement of the ankle.

    Full Text Available Las lesiones en la musculatura isquiosural son frecuentes en el fútbol profesional y han sido relacionadas con el desequilibrio entre la fuerza de los flexores y extensores de rodilla. El objetivo de nuestro estudio fue comprobar si la ratio de fuerza máxima excéntrica de flexores/concéntrica de extensores (ratio Flexexc30/Extcon240 y el ángulo de rodilla donde la musculatura isquiosural alcanza su máximo momento de fuerza, son variables útiles para establecer perfiles de riesgo de lesión isquiosural en futbolistas profesionales. Veinte jugadores de un equipo de la Segunda División de la Liga de Fútbol Profesional realizaron bilateralmente un test isocinético de flexión excéntrica de rodilla a 30º/s y extensión concéntrica de rodilla a 240º/s durante la pretemporada. Tras calcular la ratio Flexexc30/Extcon240 y el ángulo de máximo momento de fuerza, se registraron las lesiones sufridas por los jugadores a lo largo de la temporada. Los resultados mostraron que dos de los cinco jugadores lesionados presentaron ratios Flexexc30/Extcon240 menores de 0.89, valor que ha sido utilizado previamente para determinar el desequilibrio entre la musculatura flexora y extensora de rodilla y el riesgo de lesión (Croisier, Ganteaume, Binet, Genty, y Ferret, 2008. Además, otros dos de los jugadores lesionados obtuvieron ratios entre 0.93 y 1.00. Por otro lado, no se encontraron diferencias en el ángulo de máximo momento de fuerza entre jugadores lesionados y no lesionados.

A common belief, widely spread among those who participate in gambling activities, is that knowledge and expertise on football lead to better prediction skills for match outcomes. If unfounded, however, this belief should be considered as a form of “illusion of control.” The aim of this study was to examine whether football experts are better than nonexperts at predicting football match scores. Methods Two hundred and fifty-eight persons took part in the study: 21.3% as football experts, 54.3% as laypersons (non-initiated to football, and 24.4% as football amateurs. They predicted the scores of the first 10 matches of the 2008 UEFA European Football Championship. Logistic regressions were carried out to assess the link between the accuracy of the forecasted scores and the expertise of the participants (expert, amateur, layperson, controlling for age and gender. Results The variables assessed did not predict the accuracy of scoring prognosis (R2 ranged from 1% to 6%. Conclusions Expertise, age, and gender did not appear to have an impact on the accuracy of the football match prognoses. Therefore, the belief that football expertise improves betting skills is no more than a cognitive distortion called the “illusion of control.” Gamblers may benefit from psychological interventions that target the illusion of control related to their believed links between betting skills and football expertise. Public health policies may need to consider the phenomenon in order to prevent problem gambling related to football betting.

    Full Text Available The National Football League (NFL has recently received significant negative media attention surrounding the safety of its players, revolving largely around the long term health risks of playing the sport. Recent premature deaths and instances of suicide associated with chronic traumatic encephalopathy and other football related injuries have brought the sport under increased scrutiny. By comparing mortality rates of the general population to mortality rates of players using publically available data from the 1970 and 1994 NFL seasons, we test whether participation in football is significantly harmful to the longevity of the players. We conclude that, in total, players in the NFL have lower mortality rates than the general population. However, there is evidence that line players have higher mortality rates than other players and that those who played more games have higher mortality rates than those who played fewer games.

    The Star Excursion Balance Test (SEBT) is a reliable inexpensive tool used to assess dynamic postural control deficits and efficacy in the prediction of musculoskeletal injuries, but with little previous consideration for performance differences across age and skill levels. The purpose of this study was to examine differences in SEBT scores between high school and collegiate football players. Three-hundred eighteen high school football players and 180 National Collegiate Athletic Association Division I collegiate football players volunteered to participate. Star Excursion Balance Test scores were obtained bilaterally for anterior (ANT), posterolateral (PL), and posteromedial (PM) directions, and for an overall composite (COMP) score. The mean of 3 trials from each leg was normalized to stance leg length and presented as a percentage score. Bilaterally averaged scores were compared between high school and collegiate football players using separate independent t-tests. A multiple linear backward regression determined the amount of variance in SEBT scores explained by age, mass, and height. Compared with collegiate athletes, high school athletes had lower PL (72.8 ± 11.4% vs. 77.1 ± 10.2%; p football players.

    By using a 'cultural' definition of 'postmodernism' (derived from Jameson and Martin) in which postmodernism is regarded as the transgression of modern boundaries, this article traces the emergence of postmodern aspects to violent male fandom at football games since the 1960s. It is argued that at games, male fans have created imaginary masculine and national boundaries by which they have affirmed their identities but that in fighting they have sought to breach these boundaries in postmodern fashion.

    A one-year study was undertaken investigating adolescent sports injury experiences at a major sports clinic in the state of Delaware. A total of 619 athletes sustained 870 injuries, for an overall injury rate of 1.4 injuries per athlete. The largest number of injuries was recorded in football (40.2 percent), followed by boys' soccer, wrestling, baseball and girls' basketball. Severity of injury was measured by the number of days lost per injury. Cheerleading had the highest average days lost per injury (28.8), followed by girls' basketball, wrestling, boys' cross-country and girls' tennis. Inflammation, fractures and dislocations comprised 50.6 percent of all the injuries, while 50.5 percent of the injuries were located in the knee, thigh, and shoulder. Twenty-seven of the 870 injuries required surgery. PMID:1874345

    Syndesmosis sprains in the National Football League (NFL) can be a persistent source of disability, especially compared with lateral ankle injuries. This study evaluated syndesmosis and lateral ankle sprains in NFL players to allow for better identification and management of these injuries. Syndesmosis and lateral ankle sprains from a single NFL team database were reviewed over a 15-year period, and 32 NFL team physicians completed a questionnaire detailing their management approach. A comparative analysis was performed analyzing several variables, including diagnosis, treatment methods, and time lost from sports participation. Thirty-six syndesmosis and 53 lateral ankle sprains occurred in the cohort of NFL players. The injury mechanism typically resulted from direct impact in the syndesmosis and torsion in the lateral ankle sprain group (P=.034). All players were managed nonoperatively. The mean time lost from participation was 15.4 days in the syndesmosis and 6.5 days in the lateral ankle sprain groups (P⩽.001). National Football League team physicians varied treatment for syndesmosis sprains depending on the category of diastasis but recommended nonoperative management for lateral ankle sprains. Syndesmosis sprains in the NFL can be a source of significant disability compared with lateral ankle sprains. Successful return to play with nonoperative management is frequently achieved for syndesmosis and lateral ankle sprains depending on injury severity. With modern treatment algorithms for syndesmosis sprains, more aggressive nonoperative treatment is advocated. Although the current study shows that syndesmosis injuries require longer rehabilitation periods when compared with lateral ankle sprains, the time lost from participation may not be as prolonged as previously reported.

    The revelation that women first played Australian Rules football during the period of the Great War is an important element in overall understandings of how both masculine and feminine ideals were challenged and redefined by sporting practices in a time of general social flux. This paper reveals that the genesis of the women's code was in Western Australia, where contests occurred as early as 1915. Three years later, with the war nearing its conclusion, the template of women's involvement in charity matches with strong military and patriotic overtones was adopted in the state of Victoria, the code's heartland. Investigations such as this one, indicative of the complex relationships between sport and gender during the First World War, offer scope for deeper comprehension of a much-studied military conflict, and point the way forward for those that bemoan the static agenda of research into women's football.

    2014-08-01

    This article explores a new Danish football-based activity for health called Football Fitness (FF). Data are from quantitative and qualitative methods, and the theoretical framework for the analysis of the organizational form of FF is the theory of path dependency (Mahoney) and first- and second-order change (Watzlawick et al.). Theories of Pestoff concerning differences between state, market, and the civil society and theories of voluntary associations in a Danish context (Kaspersen & Ottesen; Ibsen & Seippel) are applied. This article indicates how FF is a result of the changing landscape of sport and argues that it can be beneficial to target sports organizations and include the expertise of non-profit sports clubs if the goal is to raise the physical activity level of the local community and make these long lasting. But the organizations need to consider how this is to be done. FF, established by the Danish Football Association (FA) and managed by the voluntary clubs, is one example in a Danish context. Data indicate that FF is beneficial to the clubs involved in a number of ways. Among other things, it attracts new user groups and improves the club environment, including social activities and parental environment.

  7. Biomechanics of subdural hemorrhage in American football: review of the literature in response to rise in incidence.

    2014-02-01

    The number of catastrophic head injuries recorded during the 2011 football season was the highest since data collection began in 1984--the vast majority of these cases were secondary to subdural hemorrhage (SDH). The incidence of catastrophic head injury continues to rise: the average yearly incidence from 2008 to 2012 was 238% that of the average yearly incidence from 1998 to 2002. Greater than 95% of the football players who suffered catastrophic head injury during this period were age 18 or younger. Currently, the helmet industry utilizes a standard based on data obtained at Wayne State University approximately 50 years ago that seeks to limit severity index--a surrogate marker of translational acceleration. In this manuscript, we utilize a focused review of the literature to better characterize the biomechanical factors associated with SDH following collisions in American football and discuss these data in the context of current helmet standard. Review of the literature indicates the rotational acceleration (RA) threshold above which the risk of SDH becomes appreciable is approximately 5,000 rad/s(2). This value is not infrequently surmounted in typical high school football games. In contrast, translational accelerations (TAs) experienced during even elite-level impacts in football are not of sufficient magnitude to result in SDH. This information raises important questions about the current helmet standard--in which the sole objective is limitation of TA. Further studies will be necessary to better define whether helmet constructs and quality assurance standards designed to limit RA will also help to decrease the risk of catastrophic head injury in American football.

    Groin injuries cause major problems in sports and particularly in football. Exercise is effective in treating adductor-related groin pain, but no trials have been published regarding the specific prevention of groin pain or prevention specifically targeting overuse injuries in sport using exercise programs. We performed a cluster-randomized trial including 55 football clubs representing 1211 players. The clubs were randomized to an exercise program aimed at preventing groin injuries (n=27) or to a control group training as usual (n=28). The intervention program consisted of six exercises including strengthening (concentric and eccentric), coordination, and core stability exercises for the muscles related to the pelvis. Physiotherapists assigned to each club registered all groin injuries. Twenty-two clubs in each group completed the study, represented by 977 players. There was no significant effect of the intervention (HR=0.69, 95% CI 0.40-1.19). The risk of a groin injury was reduced by 31%, but this reduction was not significant. A univariate analysis showed that having had a previous groin injury almost doubles the risk of developing a new groin injury and playing at a higher level almost triples the risk of developing a groin injury.

    The aim of the investigation was to study young football players' health. The study was conducted on 161 football players (mean age 12.3) of six children football teams of Almaty club "KAIRAT" during the competition period. It was found that 55,5% of the football players are practically healthy; 18,6% of football players have iron deficiency anemia. 32,6% of football players have caries; 5% of football players have problems of cardiopulmonary system. Investigation reveal, that in a junior sportsman was body weigh surging with downtrend during contest, testify to portability of aerobic load and in childhood unconformable of metabolism' level. This tendency was retain also in the oldest sportsman, this testify to most emulative aerobic load in comparison with junior sportsman.

    Full Text Available Since the 1990s, professional football has undergone unprecedented economic uplift worldwide. From an economic point of view, this sport has evolved into an industry that beyond the football clubs participating in the championships that are organized by the various leagues also involves rather untransparent, complementary economic operations where companies increasingly perform their specific activities on the level of medium-sized enterprises – when they are measured against traditional industrial actors –, by following their unquestionable economic interests. Football is now a scene of structural changes worldwide that are embodied in the alteration of the legal forms of enterprises backing professional football, as well as the spreading application of modern controlling, planning, risk and financial management tools. From an economic perspective, with these recently emerging elements football clubs have started to build up a modern and complex, specialized sector where the most important requirement until the end of the championship season is the maintenance of licensing conditions. In our study we wish to rely primarily on the peculiarities of German professional football, since it shows most of all the presumable mainstream of the development of football. The outsourcing of significant branches of a football undertaking into the form of an incorporated firm should be deemed as a considerable step forward in comparison with the deficient regulations of the operations of associations, regarding the economic professionality of football clubs, partially from the side of commercial law and partially from the side of shareholding law. Through the introduction of organizational and legal structures that are necessary for the football clubs to be considered professional, there are further positive effects generated for football companies. In the event of the use of the form of the incorporated football firm, it is about the transformation and

    Professional football in Europe is characterized by persistent deficits and growing debts among the majority of the top league clubs. Despite these problems, the clubs have an abnormally high survival rate. This paper focuses on this apparent paradox and poses the question: Why do only very few...... European professional football clubs go out of business even though they operate chronically on the edge of financial collapse? The paper argues that the paradox can be explained by the fact that professional football clubs operate within soft budget constraints in a way which is similar to the role...

    The medial collateral ligament is one of the most commonly injured ligaments of the knee. Most injuries result from a valgus force on the knee. The increased participation in football, ice hockey, and skiing has all contributed to the increased frequency of MCL injuries. Prophylactic knee bracing in contact sports may prevent injury; however, performance may suffer. The majority of patients who sustain an MCL injury will achieve their pre-injury activity level with non-operative treatment alo...

  4. On the flight of an American Football

    Horn, Curtis

    2007-01-01

    In this paper we examine the detailed theory of the American football in flight, with spin and air resistance included. We find the theory has much in common with the theory of a gyroscope and also rocket trajectory with a misaligned thruster. Unfortunately most of the air resistance data, for rocketry and ballistics, is for speeds of Mach 1 or higher, where the air resistance increases dramatically. We shall approximate a realistic air resistance, at the slower speeds of football flight, with a drag force proportional to cross sectional area and either $v$ or $v^2$, depending on speed, where $v$ is velocity of the football. We begin with a discussion of the motion, giving as much detail as possible without the use of complex analytic calculations. We point out the previous errors made with moments of inertia and make the necessary corrections for more accurate results. We show that the shape of an American football closely resembles a parabola of revolution.

  5. Sport injuries of the cervical spine

    International Nuclear Information System (INIS)

    The article reports on injuries of the cervical spine occurring during sports activities. An attempt is made to reconstruct the movements which led to the cervical spine injuries in question. In two cases of accidents occuring during bathing, one football accident and a toboggan accident, the injuries concerned point to hyperextension of the cervical spine as cause of the injury. In another football accident and a riding accident, the changes observed allow us to conclude that the movement leading to the injury must have been a hyperflexion. One accident occurring while jumping on the trampolin resulted in an injury of the upper cervical spine pointing to the action of a compressive force on the cervical spine in addition to the force resulting in hyperflexion.

    Full Text Available Football has surpassed the status of being a social phenomenon at a national and international scale for a long time, as it is the new “religion of the 21st century” which brings together game practitioners under its scope regardless of religion, skin colour, geographical area, culture, philosophy, gender, age which has been proven by the number of members in more than 200 FIFA member national federations. As stated in the FIFA status, “each FIFA member shall organize football games by the Laws of the Game promulgated by the International Board which has complete and exclusive jurisdiction to modify them. Football game rules bring together a set of laws under which a game, game relations and player relations must take place, actually being the single criterion to assess players” behaviour as permissible or impermissible. Football game management is provided by referees. A referee guarantees that a competition shall take place according to the Laws of the Game. However, arbitration work in football is not a profession in every sense of the word, but a social function that a person with a specific training performs regularly at various football competitions for children, youth and pros. As in any purposeful and social value activity, football arbitration too requires the set-up of a scientifically based system of recruitment, selection, training, promotion. This system requires a certain way of combining and providing theoretical training, physical training, and psychological/mental training of referees. A referee plays an important role in modern football. Therefore, a referee must be trained, selected and protected from various influences (clubs, league, political field.

  10. The toll of the gridiron: damage-associated molecular patterns and hypertension in American football.

    Science.gov (United States)

    McCarthy, Cameron G; Webb, R Clinton

    2016-01-01

    American football has unequivocally been linked to elevations in blood pressure and hypertension, especially in linemen. However, the mechanisms of this increase cannot be attributed solely to increased body weight and associated cardiometabolic risk factors (e.g.,dyslipidemia or hyperglycemia). Therefore, understanding the etiology of football-associated hypertension is essential for improving the quality of life in this mostly young population, as well as for lowering the potential for chronic disease in the future. We propose that inflammatogenic damage-associated molecular patterns (DAMPs) released into the circulation from football-induced musculoskeletal trauma activate pattern-recognition receptors of the innate immune system-specifically, high mobility group box 1 protein (HMGB1) and mitochondrial (mt)DNA which activate Toll-like receptor (TLR)4 and -9, respectively. Previously, we observed that circulating levels of these 2 DAMPs are increased in hypertension, and activation of TLR4 and -9 causes endothelial dysfunction and hypertension. Therefore, our novel hypothesis is that musculoskeletal injury from repeated hits in football players, particularly in linemen, leads to elevated circulating HMGB1 and mtDNA to activate TLRs on endothelial cells leading to impaired endothelium-dependent vasodilation, increased vascular tone, and hypertension.

    Full Text Available The main objective of this study was to perform a biomechanical analysis of three different sprint start patterns to determine the safest position in term of neck injury and Sport-Related Concussion (SRC. The second objective was to collect data on the learning process effect between football players and non-players. Three different sprint initial positions adopted by football players were studied (i.e., 4-, 3- and 2-point positions. Twenty five young healthy males, including 12 football players, participated to this study. A stereophotogrammetric system (i.e., Vicon was used to record motion patterns and body segments positions. Various measurements related to head and trunk orientation, and player field-of-view were obtained (e.g., head height, trunk bending, time to reach upright position, head speed (vertical direction and body speed (horizontal direction. Learning process was found to have no influence on studied parameters. Head redress is also delayed when adopting a 4-point position leading to a reduce field-of-view during the start and increasing therefore the probability of collision. Concerning the three different positions, the 4-point position seems to be the more dangerous because leading to higher kinetic energy than the 2- and 3-point start positions. This study proposes a first biomechanical approach to understand risk/benefit balance for athletes for those three different start positions. Results suggested that the 4-point position is the most risky for football players.

    2015-01-01

    It is currently unclear how football participation affects knee-joint muscle balance, which is widely considered a risk factor for hamstrings injury. This study compared the angle-specific functional hamstring-to-quadriceps (H:Q) ratio (hamstrings eccentric torque as a ratio of quadriceps concentric torque at the same knee-joint angle) of football players with recreationally active controls. Ten male footballers and 14 controls performed maximal voluntary isometric and isovelocity concentric and eccentric contractions (60, 240 and 400° s(-1)) of the knee extensors and flexors. Gaussian fitting to the raw torque values was used to interpolate torque values for knee-joint angles of 100-160° (60° s(-1)), 105-160° (240° s(-1)) and 115-145° (400° s(-1)). The angle-specific functional H:Q ratio was calculated from the knee flexors eccentric and knee extensors concentric torque at the same velocity and angle. No differences were found for the angle-specific functional H:Q ratio between groups, at any velocity. Quadriceps and hamstrings strength relative to body mass of footballers and controls was similar for all velocities, except concentric knee flexor strength at 400° s(-1) (footballers +40%; P < 0.01). In previously uninjured football players, there was no intrinsic muscle imbalance and therefore the high rate of hamstring injuries seen in this sport may be due to other risk factors and/or simply regular exposure to a high-risk activity.

    In football, injuries from opponent contact occur commonly in the lower extremities. FIFA the world's governing body for football requires players to wear shin guards. The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. Three commercial polypropylene shin guards (Adidas Predator™, Adidas UCL™, and Nike Mercurial™) and two custom-made carbon fiber shin guards were examined. The experimental setup had the following parts: 1) A pendulum attached a load cell at the tip (CAS Corp., Korea) and a fixed prosthetic foot equipped with a cleat to simulate an attacker's foot. 2) An artificial tibia prepared by condensed foam and reinforced by carbon fibers protected with soft clothing. 3) A multifunctional sensor system (Tekscan Corp., F-Socket System, Turkey) to record the impact on the tibia. In the low impact force trials, only 2.79-9.63 % of the load was transmitted to the sensors. When comparing for mean force, peak force and impulse, both carbon fiber shin guards performed better than the commercial ones (Adidas Predator™, Adidas UCL™, and Nike Mercurial™) (p = 0.000). Based on these same parameters, the Nike Mercurial™ provided better protection than the Adidas Predator™ and the Adidas UCL™ (p = 0.000). In the high impact force trials, only 5.16-10.90 % of the load was transmitted to the sensors. For peak force and impulse, the carbon fiber shin guards provided better protection than all the others. Carbon fiber shin guards possess protective qualities superior to those of commercial polypropylene shin guards. Key PointsShin guards decrease the risk of serious injuries.Carbon shin guards provide sufficient protection against high impact forces.Commercially available Polypropylene based shin guards do not provide sufficient protection against high impact forces.

    2014-09-01

    The head impact exposure experienced by football players at the college and high school levels has been well documented; however, there are limited data regarding youth football despite its dramatically larger population. The objective of this study was to investigate head impact exposure in middle school football. Impacts were monitored using a commercially available accelerometer array installed inside the helmets of 17 players aged 12-14 years. A total of 4678 impacts were measured, with an average (±standard deviation) of 275 ± 190 impacts per player. The average of impact distributions for each player had a median impact of 22 ± 2 g and 954 ± 122 rad/s², and a 95th percentile impact of 54 ± 9 g and 2525 ± 450 rad/s². Similar to the head impact exposure experienced by high school and collegiate players, these data show that middle school football players experience a greater number of head impacts during games than practices. There were no significant differences between median and 95th percentile head acceleration magnitudes experienced during games and practices; however, a larger number of impacts greater than 80 g occurred during games than during practices. Impacts to the front and back of the helmet were most common. Overall, these data are similar to high school and college data that have been collected using similar methods. These data have applications toward youth football helmet design, the development of strategies designed to limit head impact exposure, and child-specific brain injury criteria.

  9. Conservative treatment of anterior inferior and superior avulsion fractures of spina iliaca in adolescent amateur footballer

    Full Text Available The anterior inferior iliac spine (AIIS and the anterior superior iliac spine (ASIS avulsion fracture is a rare injury of pelvis. It usually occurs during the sport activities especially in football while hitting the ball. It is commonly misdiagnosed so that a detailed history and physical examination have a great importance. We present two cases of AIIS and ASIS avulsion fracture. Both of the patients applied to outpatient clinics with hip pain and difficulty in walking. History revealed the complaints started after hitting the ball during the football match and hip movements were limited. The patients were fifteen and sixteen years and after physical examination and radiological evaluation, avulsion fracture of the AIIS and the ASIS were diagnosed. Patients were treated conservatively with non-steroidal anti-inflammatory drugs and limited weight bearing with crutches for a month. The patients were free of pain and had full range of hip movements after one month period. At the end of the second month patients returned to active sports. AIIS and ASIS avulsion fractures are more common in adolescent football players but clinicians sometimes fail to diagnose this rare injury. We emphasize the importance of the detailed history and clinical examination and direct radiography could be enough for the diagnosis.

    2016-10-01

    The football helmet is used to help mitigate the occurrence of impact-related traumatic (TBI) and minor traumatic brain injuries (mTBI) in the game of American football. While the current helmet design methodology may be adequate for reducing linear acceleration of the head and minimizing TBI, it however has had less effect in minimizing mTBI. The objectives of this study are (a) to develop and validate a coupled finite element (FE) model of a football helmet and the human body, and (b) to assess responses of different regions of the brain to two different impact conditions - frontal oblique and crown impact conditions. The FE helmet model was validated using experimental results of drop tests. Subsequently, the integrated helmet-human body FE model was used to assess the responses of different regions of the brain to impact loads. Strain-rate, strain, and stress measures in the corpus callosum, midbrain, and brain stem were assessed. Results show that maximum strain-rates of 27 and 19 s(-1) are observed in the brain-stem and mid-brain, respectively. This could potentially lead to axonal injuries and neuronal cell death during crown impact conditions. The developed experimental-numerical framework can be used in the study of other helmet-related impact conditions. PMID:26867124

    Over the past decade, athletic-related chronic traumatic encephalopathy (CTE) has garnered a great deal of attention in the popular press and, more recently, in the scientific press. With increasing frequency, sports medicine practitioners and providers are faced with questions from the parents of high school football players about CTE and the risk posed to children who participate in this or other contact or collision sports. The purpose of this review was to summarize the research on CTE in an attempt to provide some evidence-based answers to frequently asked questions in clinics from parents.

    Full Text Available The FIFA 11+ is a structured warm-up programme specially designed to prevent injuries among football players from age 14 years and above. However, studies to prove its efficacy are generally few and it is yet to be tested in male youth footballers and among African players. The purpose of the study was to examine the efficacy of the FIFA 11+ programme in reducing the risk of injuries among male youth football players of the Lagos Junior League. A cluster randomised controlled trial was conducted. All the 20 teams (414 players aged 14 -19 years in the Premier League division were block-randomised into either an intervention (INT or a control (CON group. The INT group performed the FIFA 11+ exercises as warm-up during training sessions and the CON group performed usual warm-up. Participating teams were prospectively followed through an entire league season of 6 months in which they were visited every week to assess injured players for time-loss injuries in both groups. The primary outcomes were any injury to the players, injuries by type of exposure and injuries specific to the lower extremities. The secondary outcomes were injuries reported by body location, aetiology, mechanism and severity. In total, 130 injuries were recorded affecting 104 (25% of the 416 players. Team and player compliance with the INT was 60% and 74% respectively. Based on the primary outcome measures of the study, the FIFA 11+ programme significantly reduced the overall rate of injury in the INT group by 41% [RR = 0.59 (95% CI: 0.40 – 0.86; p = 0.006] and all lower extremity injuries by 48% [RR = 0.52 (95% CI: 0.34 – 0.82; p = 0.004]. However, the rate of injury reduction based on secondary outcomes mostly did not reach the level of statistical significance. The FIFA 11+ programme is effective in reducing the rates of injuries in male youth football players.

  15. Home advantage in Greek football.

    2014-01-01

    Home advantage as it relates to team performance at football was examined in Superleague Greece using nine seasons of game-by-game performance data, a total of 2160 matches. After adjusting for team ability and annual fluctuations in home advantage, there were significant differences between teams. Previous findings regarding the role of territorial protection were strengthened by the fact that home advantage was above average for the team from Xanthi (P =0.015), while lower for teams from the capital city Athens (P =0.008). There were differences between home and away teams in the incidence of most of the 13 within-game match variables, but associated effect sizes were only moderate. In contrast, outcome ratios derived from these variables, and measuring shot success, had negligible effect sizes. This supported a previous finding that home and away teams differed in the incidence of on-the-ball behaviours, but not in their outcomes. By far the most important predictor of home advantage, as measured by goal difference, was the difference between home and away teams in terms of kicked shots from inside the penalty area. Other types of shots had little effect on the final score. The absence of a running track between spectators and the playing field was also a significant predictor of goal difference, worth an average of 0.102 goals per game to the home team. Travel distance did not affect home advantage.

    Full Text Available In football, injuries from opponent contact occur commonly in the lower extremities. FIFA the world’s governing body for football requires players to wear shin guards. The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. Three commercial polypropylene shin guards (Adidas Predator™, Adidas UCL™, and Nike Mercurial™ and two custom-made carbon fiber shin guards were examined. The experimental setup had the following parts: 1 A pendulum attached a load cell at the tip (CAS Corp., Korea and a fixed prosthetic foot equipped with a cleat to simulate an attacker’s foot. 2 An artificial tibia prepared by condensed foam and reinforced by carbon fibers protected with soft clothing. 3 A multifunctional sensor system (Tekscan Corp., F-Socket System, Turkey to record the impact on the tibia. In the low impact force trials, only 2.79-9.63 % of the load was transmitted to the sensors. When comparing for mean force, peak force and impulse, both carbon fiber shin guards performed better than the commercial ones (Adidas Predator™, Adidas UCL™, and Nike Mercurial™ (p = 0.000. Based on these same parameters, the Nike Mercurial™ provided better protection than the Adidas Predator™ and the Adidas UCL™ (p = 0.000. In the high impact force trials, only 5.16-10.90 % of the load was transmitted to the sensors. For peak force and impulse, the carbon fiber shin guards provided better protection than all the others. Carbon fiber shin guards possess protective qualities superior to those of commercial polypropylene shin guards.

  8. Futebol mulato: racial constructs in Brazilian football

    Directory of Open Access Journals (Sweden)

    Tiago Fernandes Maranhao

    2011-05-01

    Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

    Most existing software packages for sports video analysis require manual annotation of important events in the video. Despite being the most popular sport in the United States, most American football game analysis is still done manually. Line of scrimmage and offensive team formation recognition are two statistics that must be tagged by American Football coaches when watching and evaluating past play video clips, a process which takesmanyman hours per week. These two statistics are the building blocks for more high-level analysis such as play strategy inference and automatic statistic generation. In this chapter, we propose a novel framework where given an American football play clip, we automatically identify the video frame in which the offensive team lines in formation (formation frame), the line of scrimmage for that play, and the type of player formation the offensive team takes on. The proposed framework achieves 95% accuracy in detecting the formation frame, 98% accuracy in detecting the line of scrimmage, and up to 67%accuracy in classifying the offensive team’s formation. To validate our framework, we compiled a large dataset comprising more than 800 play-clips of standard and high definition resolution from real-world football games. This dataset will be made publicly available for future comparison.

    Sports-related concussion is the most common athletic head injury with football having the highest rate among high school athletes. Traditionally, research on the biomechanics of football-related head impact has been focused at the collegiate level. Less research has been performed at the high school level, despite the incidence of concussion among high school football players. The objective of this study is to twofold: to quantify the head impact exposure in high school football, and to develop a cumulative impact analysis method. Head impact exposure was measured by instrumenting the helmets of 40 high school football players with helmet mounted accelerometer arrays to measure linear and rotational acceleration. A total of 16,502 head impacts were collected over the course of the season. Biomechanical data were analyzed by team and by player. The median impact for each player ranged from 15.2 to 27.0 g with an average value of 21.7 (±2.4) g. The 95th percentile impact for each player ranged from 38.8 to 72.9 g with an average value of 56.4 (±10.5) g. Next, an impact exposure metric utilizing concussion injury risk curves was created to quantify cumulative exposure for each participating player over the course of the season. Impacts were weighted according to the associated risk due to linear acceleration and rotational acceleration alone, as well as the combined probability (CP) of injury associated with both. These risks were summed over the course of a season to generate risk weighted cumulative exposure. The impact frequency was found to be greater during games compared to practices with an average number of impacts per session of 15.5 and 9.4, respectively. However, the median cumulative risk weighted exposure based on combined probability was found to be greater for practices vs. games. These data will provide a metric that may be used to better understand the cumulative effects of repetitive head impacts, injury mechanisms, and head impact exposure of

    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.

    Full Text Available Football is probably the world’s most popular game, with a huge number of fans. There are numerous ways in which football fans express dedication to their club and the feelings they have for their team, for example, wearing certain colours, waving banners and flags, and singing. Football anthems are nothing new for football fans, and many clubs have a long-established tradition of them. In this paper, I will address and compare the language in some popular British and Slovene football anthems, and attempt to explain its contribution to the creation of fan identity, to the fans’ sense of belonging, unity, and motivation. The linguistic analysis identities the linguistic resources used in football anthems to express attitudes, form bonds and create identities.

    Full Text Available In American football, pass interference calls can be difficult to make, especially when the timing of contact between players is ambiguous. American football history contains many examples of controversial pass interference decisions, often with fans, players, and officials interpreting the same event differently. The current study sought to evaluate the influence of experience with concepts important for officiating decisions in American football on the probability (i.e., response criteria of pass interference calls. We further investigated the extent to which such experience modulates perceptual biases that might influence the interpretation of such events. We hypothesized that observers with less experience with the American football concepts important for pass interference would make progressively more pass interference calls than more experienced observers, even when given an explicit description of the necessary criteria for a pass interference call. In a go/no-go experiment using photographs from American football games, three groups of participants with different levels of experience with American football (Football Naïve, Football Player, & Football Official made pass interference calls for pictures depicting left-moving and right-moving events. More experience was associated with progressively and significantly fewer pass interference calls (F (2, 48 = 10.4, p < .001, with Football Naïve participants making the most pass interference calls, and Football Officials the least. In addition, our data replicated a prior finding of spatial biases for interpreting left-moving images more harshly than identical right-moving images, but only in Football Players. These data suggest that experience with the concepts important for making a decision may influence the rate of decision-making, and may also play a role in susceptibility to spatial biases.

I argue that political capital of the football fans derives from the specific social and political environment that characterised the process of disintegration of the former Yugoslavia. The aim of this article is to emphasize the connection between growing nationalisation of politics and specific events that took place on football stadiums during the late 1980s and the early 1990s in the SFRY. Through the analysis of the particular events from that period, this article aims to analyse the causes that led to transformation of the subculture of the football fans to political agents par excellence.

  6. Acromioclavicular joint injuries: anatomy, diagnosis, and treatment.

    Willimon, S Clifton; Gaskill, Trevor R; Millett, Peter J

    2011-02-01

    Acromioclavicular (AC) joint injuries are common in athletic populations and account for 40% to 50% of shoulder injuries in many contact sports, including lacrosse, hockey, rugby and football. The AC joint is stabilized by static and dynamic restraints, including the coracoclavicular (CC) ligaments. Knowledge of these supporting structures is important when identifying injury and directing treatment. Management of AC injuries should be guided by severity of injury, duration of injury and symptoms, and individual patient factors. These help determine how best to guide management, and whether patients should be treated surgically or nonsurgically. Treatment options for AC injuries continue to expand, and include arthroscopic-assisted anatomic reconstruction of the CC ligaments. The purpose of this article is to review the anatomy, diagnostic methods, and treatment options for AC joint injuries. In addition, the authors' preferred reconstruction technique and outcomes are presented.

    2015-01-01

    Despite growing health and safety concerns, American football remains a vastly popular sport in the United States. Unfortunately, even with increased efforts in promoting education and hydration, the incidence of death from exertional heat stroke continues to rise. General risk factors such as hydration status, obesity, fitness level, and football-specific risk factors such as timing of training camp and equipment all contribute to the development of heat illness. At the professional level, changes have been made to effectively reduce mortality from heat stroke with no deaths since August 2001. However, there have been at least 33 total deaths at the high school and collegiate levels since this time. More efforts need to be focused at these levels to mandate exertional heat illness prevention guidelines in order to reverse this trend of mortality in our younger athletes.

    Joseph F. Clark, PHD, ATC

    2015-04-01

    Full Text Available Background: Vision training has become a component of sports enhancement training; however, quantifiable and validated improvement in visual performance has not been clearly demonstrated. In addition, there is minimal literature related to the effects of vision training on sports performance and injury risk reduction. The purpose of the current investigation was to determine the effects of vision training on peripheral vision and concussion incidence. Methods: Vision training was initiated among the University of Cincinnati football team at the beginning of the 2010 season and continued for four years (2010 to 2013. The sports vision enhancement was conducted during the two weeks of preseason camp. Typical vision training consisted of Dynavision D2 light board training, Nike strobe glasses, and tracking drills. Nike Strobe glasses and tracking drills were done with pairs of pitch-and-catch drills using footballs and tennis balls, with instructions to vary arc, speed, and trajectory. For skilled players, “high ball” drills were the focus, whereas for linemen, bounce passes and low pitch drills were stressed. Reaction time data was recorded for each athlete during every Dynavision D2 training session. We monitored the incidence of concussion during the four consecutive seasons of vision training, as well as the previous four consecutive seasons, and compared incidence of concussions (2006 to 2009 referent seasons v. 2010 to 2013 vision training seasons. Results: During the 2006-2013 pre- and regular football seasons, there were 41 sustained concussion events reported. The overall concussion incidence rate for the entire cohort was 5.1 cases per 100 player seasons. When the data were evaluated relative to vision trained versus referent untrained player seasons, a statistically significant lower rate of concussion was noted in player season in the vision training cohort (1.4 concussions per 100 player seasons compared to players who did not

    Chronic groin pain is a common problem in association football players. Normative values for the strength of hip muscles, measured in an accurate and accessible manner, are needed to gauge strength and inform return to play decisions in this group. The purpose of this study was to define normative values of hip muscle strength using handheld dynamometry. A series of reliable clinical tests that are commonly used when making return to sport decisions in athletes with chronic adductor related groin pain have been selected. One hundred and twenty adult male association football players, free from injury, were recruited. Isometric strength of the hip flexors and adductor muscles was measured using a handheld dynamometer. Mean age was 24.9 years (SD 5.9). Eighty participants (67%) had experienced groin pain in the past. Mean strength for dominant leg hip flexion was 47.3 kg (95% confidence interval 45.6-49.0), non-dominant leg hip flexion was 42.5 kg (41.1-43.9), adduction at 0 degrees hip flexion was 35.6 kg (34.1-37.1), adduction at 45 degrees was 32.0 kg (30.9-33.1), and adduction at 90 degrees was 25.5 kg (24.4-26.5). This study establishes reference ranges and predictive equations for maximal isometric contraction strength of the hip muscles in non-injured adult male association football players. This information will assist assessment and management of an athlete's return to play following injury. PMID:19574097

    While published work and media attention about football-related concussion in the USA have increased exponentially in the past few years, these injuries have in fact been written about for over a century. In this work, we undertook a selective review of the PubMed database of the published reports on concussion in football prior to 1960, with attention to the definitions used, physician attitudes, epidemiology, return to play criteria and recommendations and concerns related to long-term outcomes. Search inclusion criteria were English language, publication between the years 1900 and 1959 and studies written by healthcare professionals treating football-related injuries. Twenty-six studies met the inclusion criteria for this review, and the findings are grouped by topic area and detailed chronologically. Early sports medicine physicians struggled with many of the same issues faced today by clinicians such as honest reporting of symptoms by athletes, lack of uniform diagnosis and treatment and ambiguity over maximum 'safe' number of lifetime concussions.

    to negatively correlate with maximal knee kinematics. Conclusion: A normative database of hip and knee kinematics utilized by football athletes was developed. Position-specific analyses revealed that linemen use smaller joint motions when executing dynamic tasks but do not demonstrate passive range of motion deficits compared with other positions. Clinical Relevance: Knowledge of requisite game-like hip and knee ranges of motion is critical for developing goals for nonoperative or surgical recovery of hip and knee range of motion in the symptomatic athlete. These data help to identify playing positions that require remedial hip-related strength and conditioning protocols. Negative correlations between hip and knee kinematics indicated that constrained hip motion, as seen in linemen, could promote injurious motions at the knee. PMID:26535334

  11. Localized bioimpedance to assess muscle injury

    International Nuclear Information System (INIS)

    Injuries to lower limb muscles are common among football players. Localized bioimpedance analysis (BIA) utilizes electrical measurements to assess soft tissue hydration and cell membrane integrity non-invasively. This study reports the effects of the severity of muscle injury and recovery on BIA variables. We made serial tetra-polar, phase-sensitive 50 kHz localized BIA measurements of quadriceps, hamstring and calf muscles of three male football players before and after injury and during recovery until return-to-play, to determine changes in BIA variables (resistance (R), reactance (Xc) and phase angle (PA)) in different degrees of muscle injury. Compared to non-injury values, R, Xc and PA decreased with increasing muscle injury severity: grade III (23.1%, 45.1% and 27.6%), grade II (20.6%, 31.6% and 13.3%) and grade I (11.9%, 23.5% and 12.1%). These findings indicate that decreases in R reflect localized fluid accumulation, and reductions in Xc and PA highlight disruption of cellular membrane integrity and injury. Localized BIA measurements of muscle groups enable the practical detection of soft tissue injury and its severity. (paper)

    2011-01-01

    Full Text Available This article focuses on the experiences of a group of women footballers growing up in England. It specifically looks at their similarities and differences in relation to how they entered the world of football and whether gender relations continue to impact on both their access to and opportunities in sport. The discussion draws on information from nine semi structured interviews with women of varying ages and mixed abilities who have grown up and played football in England. The interview data highlights the prevalence of early male influence within the game and what effect the school education system has on young girls. What emerges from the interviews is that male figures tend to be the most influential in encouraging girls to play football. Developments seem to be being made at primary school level as girls’ access to football is improving. However, whatever strides are gained becomes lost as soon as the girls commence secondary school, due to the absence of football from the curriculum. As the girls reach adulthood the traditional feminine values are more highly sort after, so ‘tomboyish’ behaviours are considered unsuitable and unnatural. There are entrenched cultural attitudes towards the women’s game, which are proving hard to break down. These along with the physical barriers make women’s involvement in sport very difficult, even more so with football.

    Full Text Available This article examines the exclusion of British Asians from English professional football. At present, there are eight British Asians with professional contracts out of over 4,000 players. This statistic is increasingly noteworthy when we consider that, first, football is extremely popular across British Asian groups and, second, Britain is home to over 4 million British Asians (the UK’s largest minority ethnic group. Following a brief introduction as well as a discussion of racisms, the work will provide an overview of the barriers that have excluded British Asian football communities from the professional ranks. In particular, I shall discuss some of the key obstacles including overt racism, ‘all-Asian’ football structures and cultural differences. However, the focus of this paper is to explore the impact and persist-ing nature of institutional racism within football. With the aid of oral testimonies, this work shall present British Asian experiences of covert racism in the game. I shall therefore demonstrate that coaches/scouts (as gatekeepers have a tendency to stereotype and racialize British Asian footballers, thus exacerbating the British Asian football exclusion. Finally, the article will offer policy recommendations for reform. These recommendations, which have come out of primary and secondary research, aspire to challenge institutional racism and combat inequalities within the game.

    2006-01-01

    Full Text Available The year 1979 was a cornerstone for the football in Greece, since it practically meant the transformation of the sport’s organization from amateurism to professionalism, establishing new rules and conditions to the management of football clubs. The increased popularity of this sport and the evolutions that took place in Europe and worldwide, forced the Greek government to establish a legislative framework for the successful management of football clubs. These interventions lead to changes in many aspects of football management such as organizational and financial. The new legal environment of football management, required the organization of this sport into a more stable and professional base, following the financial standards of other corporations operating within the Greek state. By these means the government wanted to create a fair economic framework under which the football clubs would operate with common organizational, financial and tax administration rules. The aim of this paper is to present the characteristics of the new «capital form» establishment of the football clubs (Societe Anonyme, the main financial frame under which the new establishment has to operate and the tax obligations that originate from the aforementioned legal form.

    Full Text Available The aim of this paper is to analyze the financial performance of the football clubs participating within the first division of the Greek football league for a period of 14 years (1993-2006 and to propose specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs. We perform financial analysis of key accounting ratios extracted from the football club’s annual financial statements in order to explain the particular causes of the recent financial crisis which characterizes the Greek professional football league. The analysis of the clubs’ annual financial statements revealed that the Greek football clubs are highly leveraged, have intense liquidity and profitability problems and face an increased danger of financial distress, despite the increased amounts that football clubs invested during 2005. The above mentioned crisis can be attributed to aggregate financial mismanagement and political inefficiencies during the last fifteen years. The paper proposes specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs and the overall competitiveness of the Greek football league.

    Approximately 320,000 anterior cruciate ligament (ACL) injuries in the United States each year are non-contact injuries, with many occurring during a single-leg jump landing. To reduce ACL injury risk, one option is to improve muscle strength and/or the activation of muscles crossing the knee under elevated external loading. This study's purpose was to characterize the relative force production of the muscles supporting the knee during the weight-acceptance (WA) phase of single-leg jump landing and investigate the gastrocnemii forces compared to the hamstrings forces. Amateur male Western Australian Rules Football players completed a single-leg jump landing protocol and six participants were randomly chosen for further modeling and simulation. A three-dimensional, 14-segment, 37 degree-of-freedom, 92 muscle-tendon actuated model was created for each participant in OpenSim. Computed muscle control was used to generate 12 muscle-driven simulations, 2 trials per participant, of the WA phase of single-leg jump landing. A one-way ANOVA and Tukey post-hoc analysis showed both the quadriceps and gastrocnemii muscle force estimates were significantly greater than the hamstrings (p<0.001). Elevated gastrocnemii forces corresponded with increased joint compression and lower ACL forces. The elevated quadriceps and gastrocnemii forces during landing may represent a generalized muscle strategy to increase knee joint stiffness, protecting the knee and ACL from external knee loading and injury risk. These results contribute to our understanding of how muscle's function during single-leg jump landing and should serve as the foundation for novel muscle-targeted training intervention programs aimed to reduce ACL injuries in sport.

    This is the second of 2 articles on a 3-year investigation of medial collateral ligament sprains of the knee to assess the effectiveness of prophylactic knee braces in NCAA Division I college football players. Position, string, type of session, and daily brace wear were recorded. The injury rates for braced and unbraced knees were used to create an incidence density ratio. The data were stratified and simultaneously controlled for position, string, and session and evaluated for their statistical significance. The 987 Big Ten players generated 155,772 knee exposures over the study period (50% braced). Noticeable differences existed in the rates of injury for the braced and unbraced knees in almost every position during practices, depending on player or nonplayer status. When the influential factors of position, string, and session are considered, there is a consistent but not statistically significant tendency for the players wearing preventive knee braces to experience a lower injury rate than for their unbraced counterparts. For starters and substitutes in the line positions, as well as the linebackers and tight ends, there was a consistent trend toward a lower injury rate in both practices and games. The braced players in the skill positions (backs/kickers), at least during games, exhibited a higher injury rate.

  1. Nutrition and Gaelic football: review, recommendations, and future considerations.

    2015-02-01

    Gaelic football is the second most popular team sport in Ireland in terms of participation. However, very little research exists on the nutritional considerations for elite male Gaelic footballers. Gaelic football is an intermittent type field game played by two teams of fifteen players. Although amateurs, elite players may train and compete 4-5 times per week and may play for several teams. Research suggests that elite footballers are similar anthropometrically and in fitness to professional soccer players. Work-rate analysis shows that footballers experience longer durations of high-intensity (HI) activity (5-7s) and shorter rest durations than soccer players. Recent data suggests that half-forward/backs perform a greater amount of HI work during games than players in other positions. Fatigue is apparent between the first and second halves and the first and fourth quarters. The limited amount of nutritional studies conducted implies that footballers may be deficient in energy intake and may be at the lower end of recommended carbohydrate intakes to support training. A wide variety of sweat rates have been measured during training, demonstrating the importance of individual hydration strategies. Ergogenic aids such as creatine and caffeine may prove beneficial to performance, although data are extrapolated from other sports. Due to the lack of research in Gaelic football, further population specific studies are required. Future areas of research on the impact of nutrition on Gaelic football performance are examined. In particular, the creation of a test protocol mimicking the activity patterns and intensity of a Gaelic football game is warranted.

    Acute injuries in sport are still a problem where limited knowledge of incidence and severity in different sports at national level exists. In Sweden, 80% of the sports federations have their mandatory injury insurance for all athletes in the same insurance company and injury data are systematically kept in a national database. The aim of the study was to identify high-risk sports with respect to incidence of acute and severe injuries in 35 sports reported to the database. The number and incidences of injuries as well as injuries leading to permanent medical impairment (PMI) were calculated during 2008-2011. Each year approximately 12,000 injuries and 1,162,660 licensed athletes were eligible for analysis. Eighty-five percent of the injuries were reported in football, ice hockey, floorball, and handball. The highest injury incidence as well as PMI was in motorcycle, handball, skating, and ice hockey. Females had higher risk of a PMI compared with males in automobile sport, handball, floorball, and football. High-risk sports with numerous injuries and high incidence of PMI injuries were motorcycle, handball, ice hockey, football, floorball, and automobile sports. Thus, these sports ought to be the target of preventive actions at national level. PMID:25850826

    Full Text Available The purpose of this study to determine the relationship between Mobbing and Level of Job Satisfaction among football trainers in football clubs. In this research the data was gathered randomly from Turkish football trainers who had participated in Turkish trainer development seminar 2010-2011 which was organized jointly by Football Federation of Turkey and Turkey Football Coaches Association. Negative Acts Questionnaire (NAQ which was developed by Einarsen, Raknes, Matthiesen and Hellesoy and adopted by Cemaloglu into Turkish version and Minnesota Satisfaction Questionnaire (MSQ were applied to all participants. 524 of them answered the questionnaire and 515 out of 524 were evaluated. The answers from the questionnaire were analyzed by Reliability analysis and Correlation analysis. Sub dimensions of NAQ are positively correlated with moderate level. The highest positive correlation was found between organizational communication and duty. On the other hand the lowest correlation was found between organizational communication and social relationships. It is easily seen that from the analysis, level of Job satisfaction of football trainers who was exposed to mobbing is lower than who was not exposed. As a result of this survey there is a relationship between level of job satisfaction and mobbing especially in younger football trainers.

    The sensitivity of the human visual system decreases dramatically with increasing distance from the fixation location in a video frame. Accurate prediction of a viewer's gaze location has the potential to improve bit allocation, rate control, error resilience, and quality evaluation in video compression. Commercially, delivery of football video content is of great interest because of the very high number of consumers. In this paper, we propose a gaze location prediction system for high definition broadcast football video. The proposed system uses knowledge about the context, extracted through analysis of a gaze tracking study that we performed, to build a suitable prior map. We further classify the complex context into different categories through shot classification thus allowing our model to prelearn the task pertinence of each object category and build the prior map automatically. We thus avoid the limitation of assigning the viewers a specific task, allowing our gaze prediction system to work under free-viewing conditions. Bayesian integration of bottom-up features and top-down priors is finally applied to predict the gaze locations. Results show that the prediction performance of the proposed model is better than that of other top-down models that we adapted to this context. PMID:23996558

  9. Consequences of repeated blood-brain barrier disruption in football players.

    Directory of Open Access Journals (Sweden)

    Nicola Marchi

    Full Text Available The acknowledgement of risks for traumatic brain injury in American football players has prompted studies for sideline concussion diagnosis and testing for neurological deficits. While concussions are recognized etiological factors for a spectrum of neurological sequelae, the consequences of sub-concussive events are unclear. We tested the hypothesis that blood-brain barrier disruption (BBBD and the accompanying surge of the astrocytic protein S100B in blood may cause an immune response associated with production of auto-antibodies. We also wished to determine whether these events result in disrupted white matter on diffusion tensor imaging (DT scans. Players from three college football teams were enrolled (total of 67 volunteers. None of the players experienced a concussion. Blood samples were collected before and after games (n = 57; the number of head hits in all players was monitored by movie review and post-game interviews. S100B serum levels and auto-antibodies against S100B were measured and correlated by direct and reverse immunoassays (n = 15 players; 5 games. A subset of players underwent DTI scans pre- and post-season and after a 6-month interval (n = 10. Cognitive and functional assessments were also performed. After a game, transient BBB damage measured by serum S100B was detected only in players experiencing the greatest number of sub-concussive head hits. Elevated levels of auto-antibodies against S100B were elevated only after repeated sub-concussive events characterized by BBBD. Serum levels of S100B auto-antibodies also predicted persistence of MRI-DTI abnormalities which in turn correlated with cognitive changes. Even in the absence of concussion, football players may experience repeated BBBD and serum surges of the potential auto-antigen S100B. The correlation of serum S100B, auto-antibodies and DTI changes support a link between repeated BBBD and future risk for cognitive changes.

    Wide variations in the definitions and methodologies used for studies of injuries in rugby union have created inconsistencies in reported data and made interstudy comparisons of results difficult. The International Rugby Board established a Rugby Injury Consensus Group (RICG) to reach an agreement on the appropriate definitions and methodologies to standardise the recording of injuries and reporting of studies in rugby union. The RICG reviewed the consensus definitions and methodologies previously published for football (soccer) at a meeting in Dublin in order to assess their suitability for and application to rugby union. Following this meeting, iterative draft statements were prepared and circulated to members of the RICG for comment; a follow-up meeting was arranged in Dublin, at which time all definitions and procedures were finalised. At this stage, all authors confirmed their agreement with the consensus statement. The agreed document was presented to and approved by the International Rugby Board Council. Agreement was reached on definitions for injury, recurrent injury, non-fatal catastrophic injury, and training and match exposures, together with criteria for classifying injuries in terms of severity, location, type, diagnosis and causation. The definitions and methodology presented in this consensus statement for rugby union are similar to those proposed for football. Adoption of the proposals presented in this consensus statement should ensure that more consistent and comparable results will be obtained from studies of injuries within rugby union.

    2016-01-01

    Background: Increased ambient temperature has been implicated in increased physical aggression, which has important practical consequences. The present study investigates this established relationship between aggressive behavior and ambient temperature in the highly aggressive context of professional football in the National Football League (NFL). Methods: Using a publicly available dataset, authors conducted multiple hierarchical regression analyses on game-level data (2326 games). Results: The analysis revealed that temperature positively predicted aggressive penalties in football, and that this relationship was significant for teams playing at home but not for visiting teams. Conclusion: These results indicate that even in the aggressive context of football, warmer weather contributes to increased violence. Further, the presence of the heat-aggression relationship for the home team suggests that the characteristics of interacting groups may influence whether heat would have an adverse effect on the outcome of those interactions.

    In a recent paper in TPT, DiLisi and Rarick used the National Football League "Deflategate" controversy to introduce to physics students the physics of a bouncing ball. In this paper, we measure and analyze the environmental effects of time, ambient temperature, and moisture on the internal pressure of an NFL football. We focus on the rate of pressure recovery that occurs when a cold football (either wet or dry) is returned to the warm locker room environment where the pressure was initially measured. Both studies stem from the so-called NFL "Deflategate" controversy in which footballs that initially met a minimum internal pressure requirement were rechecked at halftime of the AFC Championship game, and in some cases were reported to have fallen below the minimum pressure requirement. The question is whether the pressure changes were due to environmental exposure or rather to some air being released from the balls, or both.

    Full Text Available Football may be a physical and sport activities able to improve motor and cognitive growth in children. Therefore the aim of this study was to assess whether a Football Training Program taken over 6 months would improve motor and cognitive performances in children. Motor skills concerned coordinative skills, running and explosive legs strength. Cognitive abilities involved visual discrimination times and visual selective attention times.Forty-six children with chronological age of ~9.10 years, were divided into two groups: Group 1 (n=24 attended a Football Exercise Program and Group 2 (n=22 was composed of sedentary children.Their abilities were measured by a battery of tests including motor and cognitive tasks. Football Exercise Program resulted in improved running, coordination and explosive leg strength performances as well as shorter visual discrimination times in children regularly attending football courses compared with their sedentary peers. On the whole these results support the thesis that the improvement of motor and cognitive abilities is related not only to general physical activity but also to specific ability related to the ball. Football Exercise Programs is assumed to be a natural and enjoyable tool to enhance cognitive resources as well as promoting and encouraging the participation in sport activities from early development.

In 1998, a new factor came to influence this scenario: it was sanctioned the Law no. 9.615, know as “Lei Pelé”, which extinguished the pass of football players. Before that, football clubs have as their major income source the transfer of players. After this regulatory change, clubs were obligated to develop alternative sources of income. The current article intends to analyze this new scenario and to propose options to the clubs not only related to the players transfer market. To do that, it will be shown a comparative study between the Brazilian football and the European Football, identifying the strategies and the results. In this context, public support and the relation between clubs and their clients appeared as the major items.

    Luke W Hogarth

    Full Text Available This study determined the physical fitness, match-activity profiles and physiological responses of representative tag football players and examined the relationship between physical fitness and the match-activity profile. Microtechnology devices and heart rate (HR chest straps were used to determine the match-activity profiles of sixteen tag football players for five matches during the 2014 Australian National Championships. The relationships between lower body muscular power, straight line running speed and Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2 and the match-activity profile were examined using Pearson's correlation coefficients. Outside players had greater lower body muscular power (ES = 0.98 and straight line running speed (ES = 1.03-1.18 than inside players, and also covered greater very high-speed running (VHSR distance/min (ES = 0.67 and reached higher peak running speeds (ES = 0.95 during matches. Inside and outside players performed a similar number of repeated high-intensity effort (RHIE bouts and reported similar mean and maximum efforts per RHIE bout. However, there were differences between playing positions for mean and maximal RHIE effort durations (ES = 0.69-1.15 and mean RHIE bout recovery (ES = 0.56. Inside and outside players also reported small to moderate differences (ES = 0.43-0.80 for times spent in each HR zone. There were a number of moderate to very large correlations between physical fitness measures and match-activity profile variables. This study found lower body muscular power, straight line running speed and Yo-Yo IR2 to be related to the match-activities of representative tag football players, although differences between inside and outside players suggest that athlete testing and training practices should be modified for different playing positions.

  19. A network theory analysis of football strategies

    CERN Document Server

    Peña, Javier López

    2012-01-01

    We showcase in this paper the use of some tools from network theory to describe the strategy of football teams. Using passing data made available by FIFA during the 2010 World Cup, we construct for each team a weighted and directed network in which nodes correspond to players and arrows to passes. The resulting network or graph provides a direct visual inspection of a team's strategy, from which we can identify play pattern, determine hot-spots on the play and localize potential weaknesses. Using different centrality measures, we can also determine the relative importance of each player in the game, the `popularity' of a player, and the effect of removing players from the game.

    Greenhough, J.; Birch, P. C.; Chapman, S. C.; Rowlands, G.

    2002-12-01

    We analyse the distributions of the number of goals scored by home teams, away teams, and the total scored in the match, in domestic football games from 169 countries between 1999 and 2001. The probability density functions (PDFs) of goals scored are too heavy-tailed to be fitted over their entire ranges by Poisson or negative binomial distributions which would be expected for uncorrelated processes. Log-normal distributions cannot include zero scores and here we find that the PDFs are consistent with those arising from extremal statistics. In addition, we show that it is sufficient to model English top division and FA Cup matches in the seasons of 1970/71-2000/01 on Poisson or negative binomial distributions, as reported in analyses of earlier seasons, and that these are not consistent with extremal statistics.

    2014-01-01

    Resistance training (RT) is an integral part of National Collegiate Athletic Association (NCAA) Division I Football performance programs. In the sport of football, there are several components that a strength and conditioning coach must be aware of. These include body mass, size, strength, power, speed, conditioning, and injury prevention, among others. The purpose of this study was to investigate if the RT component of a performance program could be prioritized for specific results using a nonlinear training model, grouping athletes by eligibility year. The NCAA Division I football student athletes were placed into 3 separate groups based on the playing year. All subjects participated in a 10-week, 4 days·week-1 off-season summer resistance training program. The training of group 1 (n = 20, age: 18.95 ± 0.76 years, height: 186.63 ± 7.21 cm, body mass: 97.66 ± 18.17 kg, playing year: 1.05 ± 0.22 years) prioritized hypertrophy-based RT to gain body mass. The training of group 2 (n = 20, age: 20.05 ± 1.05 years, height: 189.42 ± 5.49 cm, body mass: 106.99 ± 13.53 kg, and playing year: 2.35 ± 0.75 years) prioritized strength-based RT to gain strength. The training of group 3 (n = 20, age: 21.05 ± 1.10 years, height: 186.56 ± 6.73 cm, body mass: 109.8 ± 19.96 kg, playing year: 4.4 ± 0.50 years) prioritized power-based RT to gain power. Performance tests were evaluated during the first weeks of March (Spring) and August (Fall). The test measures included body mass (kilograms), 1-repetition maximum (1RM) bench press (kilograms), 1RM back squat (kilograms), 1RM power clean (kilograms), and countermovement vertical jump (CMVJ) height (centimeters). The primary findings of this investigation were as follows: group 1 saw significant increases in bench press maximum, back squat maximum, and power clean maximum (p ≤ 0.05). Group 2 saw significant increases in bench press maximum, back squat maximum, and power clean maximum (p ≤ 0.05). Group 3 saw a significant

    On 11 May 1985 the main stand of Bradford City Football Club caught fire. Within four minutes the stand was alight from end to end. Fifty three people were burnt to death and about 250 injured; 83 required admission to hospital, and 55 of these were treated by primary excision of their burns and skin grafting. In such disasters the help of staff from other hospitals and areas is essential. Patients should be assessed to see whether they have burns that will ultimately be fatal; if they have they should not be sent to regional burns units, where they would take up beds that could be used for patients with treatable burns. All districts should ensure that their plans for accidents in which burns injuries predominate are adequate. Images FIG 1 FIG 2 FIG 3 FIG 4 PMID:3929974

  7. Mechanisms of team-sport-related brain injuries in children 5 to 19 years old: opportunities for prevention.

    Directory of Open Access Journals (Sweden)

    Michael D Cusimano

    Full Text Available BACKGROUND: There is a gap in knowledge about the mechanisms of sports-related brain injuries. The objective of this study was to determine the mechanisms of brain injuries among children and youth participating in team sports. METHODS: We conducted a retrospective case series of brain injuries suffered by children participating in team sports. The Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP database was searched for brain injury cases among 5-19 year-olds playing ice hockey, soccer, American football (football, basketball, baseball, or rugby between 1990 and 2009. Mechanisms of injury were classified as "struck by player," "struck by object," "struck by sport implement," "struck surface," and "other." A descriptive analysis was performed. RESULTS: There were 12,799 brain injuries related to six team sports (16.2% of all brain injuries registered in CHIRPP. Males represented 81% of injuries and the mean age was 13.2 years. Ice hockey accounted for the greatest number of brain injuries (44.3%, followed by soccer (19.0% and football (12.9%. In ice hockey, rugby, and basketball, striking another player was the most common injury mechanism. Football, basketball, and soccer also demonstrated high proportions of injuries due to contact with an object (e.g., post among younger players. In baseball, a common mechanism in the 5-9 year-old group was being hit with a bat as a result of standing too close to the batter (26.1% males, 28.3% females. INTERPRETATION: Many sports-related brain injury mechanisms are preventable. The results suggest that further efforts aimed at universal rule changes, safer playing environments, and the education of coaches, players, and parents should be targeted in maximizing prevention of sport-related brain injury using a multifaceted approach.

    Full Text Available Music as a fact which surrounds human being in all fields of life has been used as a tool for healing, communication, entertainment and also used in production wi th focusing function, in warfare with encouraging function and in sports with motivating function. (Colombe, 2006:34; Aydoğan, 2001:23. Shortly it can be claimed that music that is always in previous of movement is in relation with sports which is compose d by moving. The cheerings in sports culture are initially considered as very easy and si mple. However it can be claimed that they provide a deep and complex structure on behalf of the social events of their era. Cheerings as a part of intangible sports legacy provide the contiunity of tradition and incentive of creativity as an oral traditional form. The emotions are coming around and the memories are remembered through stimulating by music. Football always keep the attention alive therefore it gets a place in the society as a tool which entertains masses and unifies them through the same goal. The industralised structure of football is accepted as a tool of social engineering with the help of media which provides the power to create and change the agendum. In this meaning it is mentioned that football indicates the life styles, be liefs and values. In our study we will search the cheerings of spectators on the content of their relations with social conditions since 20th century in which modern football has been initially played in organised forms. In this context it is purposed to contribute into sociological analysis of modern football throughout the social meanings of football matches in different eras and socio - economic conditions and the relations between societies and football. There will be performed a theoretical research based on literature search.

    The public has recently raised concerns regarding potential human health and environmental risks associated with tire crumb constituents in the artificial turf of football fields. The aim of the present study was to develop an environmental analysis drawing a comparison between artificial turf football fields and urban areas relative to concentrations of particles (PM10 and PM2.5) and related polycyclic aromatic hydrocarbons (PAHs), aromatic hydrocarbons (BTXs), and mutagenicity of organic extracts from PM10 and PM2.5. No significant differences were found between PM10 concentrations at an urban site and on a turf football field, both during warm and in cold seasons, either with or without on-field activity. PM2.5 concentrations were significantly greater at the urban site in the cold season as was the ratio of PM2.5 to PM10. BTXs were significantly greater at urban sites than on turf football fields on both on warm and cold days. The ratio of toluene to benzene (T/B ratio) was always comparable with that of normal urban conditions. The concentration of PAHs on the monitored football fields was comparable with urban levels during the two different sampling periods, and the contribution of PAHs released from the granular material was negligible. PM10 organic extract mutagenicity for artificial turf football fields was greater, whereas PM2.5 organic extract mutagenicity was lower, compared with the urban site studied. However, both organic extract mutagenicity values were comparable with the organic extract mutagenicity reported in the literature for urban sites. On the basis of environmental monitoring, artificial turf football fields present no more exposure risks than the rest of the city.

    Training load (TL) is monitored with the aim of making evidence-based decisions on appropriate loading schemes to reduce injuries and enhance team performance. However, little is known in detail about the variables of load and methods of analysis used in high-level football. Therefore, the aim of this study was to provide information on the practices and practitioners' perceptions of monitoring in professional clubs. Eighty-two high-level football clubs from Europe, the United States, and Australia were invited to answer questions relating to how TL is quantified, how players' responses are monitored, and their perceptions of the effectiveness of monitoring. Forty-one responses were received. All teams used GPS and heart-rate monitors during all training sessions, and 28 used rating of perceived exertion. The top-5-ranking TL variables were acceleration (various thresholds), total distance, distance covered above 5.5 m/s, estimated metabolic power, and heart-rate exertion. Players' responses to training are monitored using questionnaires (68% of clubs) and submaximal exercise protocols (41%). Differences in expected vs actual effectiveness of monitoring were 23% and 20% for injury prevention and performance enhancement, respectively (P human resources scored highest, followed by coach buy-in. The discrepancy between expected and actual effectiveness appears to be due to suboptimal integration with coaches, insufficient human resources, and concerns over the reliability of assessment tools. Future approaches should critically evaluate the usefulness of current monitoring tools and explore methods of reducing the identified barriers to effectiveness. PMID:26456711

    2015-10-01

    Higher ACL injury rates have been recorded in cleats with higher torsional resistance in American football, which warrants better understanding of shoe/stud-dependent joint kinetics. The purpose of this study was to determine differences in knee and ankle kinetics during single-leg land cuts and 180° cuts on synthetic infilled turf while wearing 3 types of shoes. Fourteen recreational football players performed single-leg land cuts and 180° cuts in nonstudded running shoes (RS) and in football shoes with natural (NTS) and synthetic turf studs (STS). Knee and ankle kinetic variables were analyzed with a 3 × 2 (shoe × movement) repeated-measures ANOVA (P < .05). A significant shoe-by-movement interaction was found in loading response peak knee adduction moments, with NTS producing smaller moments compared with both STS and RS only in 180° cuts. Reduced peak negative plantar flexor powers were also found in NTS compared with STS. The single-leg land cut produced greater loading response and push-off peak knee extensor moments, as well as peak negative and positive extensor and plantar flexor powers, but smaller loading peak knee adduction moments and push-off peak ankle eversion moments than 180° cuts. Overall, the STS and 180° cuts resulted in greater frontal plane knee loading and should be monitored for possible increased ACL injury risks.

    2016-06-01

    Pediatric ankle injuries are common, especially in athletes; however, the incidence of syndesmosis injuries in children has been scarcely reported. Injuries to the ankle syndesmosis, termed "high ankle sprains," can affect high-level and recreational athletes and have been related to delayed return to play, persistent pain, and adult injuries have been associated with long-term disability. Syndesmotic injuries do occur in children, especially those who participate in sports that involve cutting and pivoting (football, soccer) or sports with rigid immobilization of the ankle (skiing, hockey). Unstable pediatric syndesmosis injuries requiring surgical fixation are often associated with concomitant fibular fracture in skeletally mature children. Physician vigilance and careful clinical examination coupled with appropriate radiographs can determine the extent of the injury in the majority of circumstances. PMID:27100034

    In rugby union football the tackle is the most frequently executed skill and one most associated with injury, including shoulder injury to the tackler. Despite the importance of the tackle, little is known about the magnitude of shoulder forces in the tackle and influencing factors. The objectives of the study were to measure the shoulder force in the tackle, as well as the effects of shoulder padding, skill level, side of body, player size, and experimental setting on shoulder force. Experiments were conducted in laboratory and field settings using a repeated measures design. Thirty-five participants were recruited to the laboratory and 98 to the field setting. All were male aged over 18 years with rugby experience. The maximum force applied to the shoulder in an active shoulder tackle was measured with a custom built forceplate incorporated into a 45 kg tackle bag. The overall average maximum shoulder force was 1660 N in the laboratory and 1997 N in the field. This difference was significant. The shoulder force for tackling without shoulder pads was 1684 N compared to 1635 N with shoulder pads. There was no difference between the shoulder forces on the dominant and non-dominant sides. Shoulder force reduced with tackle repetition. No relationship was observed between player skill level and size. A substantial force can be applied to the shoulder and to an opponent in the tackle. This force is within the shoulder's injury tolerance range and is unaffected by shoulder pads.

    Full Text Available The purpose of this study was the description of sports injuries sustained by campers at summer camps, aged 7-15 years. A sample of 8 camps from the Greek camp population participated in this sport injury surveillance study. Doctors and camp directors completed reports detailing the number of sports injuries events sustained and provided specific information about each event. During the period of the study, 337 sport injury reports were completed. A total of 237 (70.3% boys and 100 (29.7% girls reported having a sport injury. Age of campers sustaining a sport injury was 10-12 years old (60.8%. The frequency of sports injuries was highest during the first camp season. The leading causes of sports injuries in children’s were: falls, crushed by object, collision with other person and slips. Cut/scratch injuries were the most common diagnoses (38.9%. Football, basketball and volleyball were the most frequent sport activities for injuries. Reports based surveillance systems can be successfully used to conducts sport injury surveillance among children attending summer camps. Data collected via such systems can be used to calculate sports injury rates, to describe patterns of sport injury and to identify risk factors for camper – related sport injuries. The results provide necessary information to develop prevention interventions to decrease the number of youth whose camp experiences are negatively affected by sport injury.

  7. A Topic Model Approach to Representing and Classifying Football Plays

    KAUST Repository

    Varadarajan, Jagannadan

    2013-09-09

    We address the problem of modeling and classifying American Football offense teams’ plays in video, a challenging example of group activity analysis. Automatic play classification will allow coaches to infer patterns and tendencies of opponents more ef- ficiently, resulting in better strategy planning in a game. We define a football play as a unique combination of player trajectories. To this end, we develop a framework that uses player trajectories as inputs to MedLDA, a supervised topic model. The joint maximiza- tion of both likelihood and inter-class margins of MedLDA in learning the topics allows us to learn semantically meaningful play type templates, as well as, classify different play types with 70% average accuracy. Furthermore, this method is extended to analyze individual player roles in classifying each play type. We validate our method on a large dataset comprising 271 play clips from real-world football games, which will be made publicly available for future comparisons.

  8. Arthrography in sport injuries of the knee joint

    International Nuclear Information System (INIS)

    The arthrography is one of the most important diagnostic methods of sport injuries of the knee joint. The examination must give an exact information to the surgeon; a good technique and standard X-rays are an absolute postulate. The submitted examinations are based on 6687 arthrographies during a period of 5 years. The arthrography should not be carried out before the acute symptomatology has ceased, usually after an interval of 2-3 weeks. Most frequently are the meniscus injuries by rotary traumas of the knee-joint. Football as the most popular sport is responsible for more than 50% of the injuries, followed by skiing, handball and jogging. (orig.)

    Science.gov (United States)

    Quintner, J L

    1995-07-01

    The vehement scientific debate which took place in Australia in the 1980s over the epidemic of the chronic cervicobrachial pain syndrome known as repetition strain injury (RSI) was remarkable for the accompanying social commentary offered by many of the medical participants. This commentary was to have a profound effect on relationships between individual doctors and their patients with RSI. It reflected and reinforced the prevailing stereotypes within Australian society, not only of working women, but also of recipients of workers' compensation payments. On the other hand, some of the medical responses to the epidemic were severely criticized by social scientists who analysed the epidemic. In the process of such criticism, a number of stereotypes of doctors were also reinforced. PMID:7626774

    2011-04-01

    Full Text Available The first broadcast of a World Cup footballon television, to Brazil was in 1970, via Embratel. Before that, the people followed the games of the Brazilian team on the radio. Gradually, the owners of television networks realized that football could generate good financial results, with the exposing of advertisements during the broadcasts, similar to what was already done on the radio. Thus, the television, focused on the growth of audience and number of advertisers, covered football with a language of entertainment. The narration of the matches, in which the figure of the narrator is more like that of an entertainer, and improvement of the transmission technologies that improve the image quality every day, take away from football the characteristic of being just a sport to occupy the place of an entertainment. In this context, the sport becomes an article of purchase and sale. The purpose of this study is to demonstrate how this entertainment language was made up on Brazilian television, based on the broadcast sports, especially football, and like the television, which represented a technological leapin the country over the radio, assumed of the sport, country’s most popular as a commodity, interfering with the dynamics of Brazilian society. Finally, an attempt to understand how the researches that allow a technological development change behaviors and vice versa, that is, how the demands of society lead to a race to develop new technologies.

    2005-08-01

    The purpose of this study was to present a profile of body size and composition of National Football League (NFL) players prior to the start of the regular season. Fifty-three members of the Indianapolis Colts professional football team were measured for height, body mass, and percentage body fat using the BOD POD air-displacement plethysmography system during summer camp of the 2003 football season. These data were categorized by position for comparison with previous studies of NFL football players. The relationships observed were as follows (= represents nonsignificant; > represents p Linebackers > Running Backs = Wide Receivers = Defensive Backs. Body Mass: Offensive Line = Defensive Line > Tight Ends = Linebackers > Running Backs = Quarterbacks/ Kickers/Punters > Wide Receivers = Defensive Backs. Percentage Body Fat: Offensive Line > Defensive Line > Quarterbacks/ Kickers/Punters = Linebackers = Tight Ends > Running Backs = Wide Receivers = Defensive Backs. Comparisons to teams in the 1970s indicate that body mass has increased only for offensive and defensive linemen; however, height and body fat among player positions have not dramatically changed. Furthermore, the body mass index is not an accurate measure or representation of body fat or obesity in NFL players. These data provide a basic template for size profiles and differences among various positions and allow comparisons with other studies for changes in the NFL over the past 3 decades.

  15. Automatic recognition of offensive team formation in american football plays

    KAUST Repository

    Atmosukarto, Indriyati

    2013-06-01

    Compared to security surveillance and military applications, where automated action analysis is prevalent, the sports domain is extremely under-served. Most existing software packages for sports video analysis require manual annotation of important events in the video. American football is the most popular sport in the United States, however most game analysis is still done manually. Line of scrimmage and offensive team formation recognition are two statistics that must be tagged by American Football coaches when watching and evaluating past play video clips, a process which takes many man hours per week. These two statistics are also the building blocks for more high-level analysis such as play strategy inference and automatic statistic generation. In this paper, we propose a novel framework where given an American football play clip, we automatically identify the video frame in which the offensive team lines in formation (formation frame), the line of scrimmage for that play, and the type of player formation the offensive team takes on. The proposed framework achieves 95% accuracy in detecting the formation frame, 98% accuracy in detecting the line of scrimmage, and up to 67% accuracy in classifying the offensive team\\'s formation. To validate our framework, we compiled a large dataset comprising more than 800 play-clips of standard and high definition resolution from real-world football games. This dataset will be made publicly available for future comparison. © 2013 IEEE.

  16. A Field Study of Low-Top vs. Mid-Top vs. High-Top American Football Cleats

    Calvin W. Daack

    2014-11-01

    Full Text Available Few studies have examined the role of shoe height in the context of American football cleats. Eighteen adult males (28.4 ± 1.9 years, 182.3 ± 0.6 cm, 75.7 ± 1.6 kg performed four football drills (60-yd dash, 54-yd cutting drill, 5-10-5 drill [pro agility drill], and ladder jumping drill in low-top, mid-top, and high-top American football cleats. Drill-specific performance outcomes were measured after each drill, and the subjects’ ankle range-of-motion (dorsiflexion, plantarflexion, eversion, inversion and perception of the footwear (comfort, heaviness, stability were assessed before and after each drill sequence. Performance outcomes were not influenced by shoe height. The high-top cleat limited dorsiflexion and inversion, but not plantarflexion or eversion, compared to low-top and mid-top cleats. Athletes rated the high-top cleats as less comfortable and heavier than either the low-top or mid-top cleats, but perceived the mid-top and high-top cleats to be equally stable to each other, and both more stable than the low-top cleats. Range-of-motion and performance scores did not change as a result of acute exercise. These findings suggest that high-top cleats may limit ankle motions associated with injury without deleteriously influencing performance, though athletes may not perceive the high-top cleats as favorably as low- or mid-top cleats.

    2014-10-01

    The aim of this study was to determine whether the cumulative effects of head impacts from a season of high school football produce magnetic resonance imaging (MRI) measureable changes in the brain in the absence of clinically diagnosed concussion. Players from a local high school football team were instrumented with the Head Impact Telemetry System (HITS™) during all practices and games. All players received pre- and postseason MRI, including diffusion tensor imaging (DTI). Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) was also conducted. Total impacts and risk-weighted cumulative exposure (RWE), including linear (RWELinear), rotational (RWERotational), and combined components (RWECP), were computed from the sensor data. Fractional, linear, planar, and spherical anisotropies (FA, CL, CP, and CS, respectively), as well as mean diffusivity (MD), were used to determine total number of abnormal white matter voxels defined as 2 standard deviations above or below the group mean. Delta (post-preseason) ImPACT scores for each individual were computed and compared to the DTI measures using Spearman's rank correlation coefficient. None of the players analyzed experienced clinical concussion (N=24). Regression analysis revealed a statistically significant linear relationship between RWECP and FA. Secondary analyses demonstrated additional statistically significant linear associations between RWE (RWECP and RWELinear) and all DTI measures. There was also a strong correlation between DTI measures and change in Verbal Memory subscore of the ImPACT. We demonstrate that a single season of football can produce brain MRI changes in the absence of clinical concussion. Similar brain MRI changes have been previously associated with mild traumatic brain injury.

    Full Text Available Objective: The purpose of this study is to investigate the effect of football on sole peak pressure, average maximal pressure and pressure–time integral soles of professional female football players and healthy individuals. Methods: 22 female football players (18,80 ± 2,2 age and 28 female volunteers (27,5 ±6,6 age (as the control grouphaving no foot complaints were included in the study. In the research EMED-SF (Novel GmbH, Munich, Germany plantar pressure analysis system was used. It was examined whether there was any statistically significant difference between the experiment and control group means using non-parametric Mann Whitney U test, the size of the linear relation between physical structure and variables of sole was examined by calculating Pearson’s (r coefficient. In the measurements 95% reliability range and P < 0.01 – 0.05 were accepted as significance level. Results: At the end of the measurements, it was found that there were significant differences between the female football players and control group in right foot 2 left feet 1st, 2nd,3rd,4th metatarsal heads sole 11 contact areas peak pressure and in the 3rd, 4th and 5th toes, at average maximal pressure in right and left foot in 2nd metatarsalheads and time pressure integral in right foot 2nd and 3rd metatarsalheads and left foot heel medial, heel lateral, 2nd,3rd and 4thmetatarsalheads. Conclusion: In our findings, it was found that the pressure in football players’ sole front interior regions was higher than both the control group and the other regions in their own feet. It was determined that the particularly the crampons used by the football players were insufficient to protect the sole and failed to prevent permanent sole pressure parameters. As a result, Football players’ excessive pressing against their soles in forcing movements in long term exercises and matches are indicated to cause change in the sportsmen’s sole pressure regions and values.

    Full Text Available Background: There is no comprehensive study of the costs of horse-related workplace injuries to Australian Thoroughbred racing jockeys. Objectives: To analyse the characteristics of insurance payments and horse-related workplace injuries to Australian jockeys during Thoroughbred racing or training. Methods: Insurance payments to Australian jockeys and apprentice jockeys as a result of claims for injury were reviewed. The cause and nature of injuries, and the breakdown of payments associated with claims were described. Results: The incidence of claims was 2.1/1000 race rides, with an average cost of AUD 9 million/year. Race-day incidents were associated with 39% of claims, but 52% of the total cost. The mean cost of race-day incidents (AUD 33,756 was higher than non-race day incidents (AUD 20,338. Weekly benefits and medical expenses made up the majority of costs of claims. Fractures were the most common injury (29.5%, but head injuries resulting from a fall from a horse had the highest mean cost/claim (AUD 127,127. Conclusions: Costs of workplace injuries to the Australian Thoroughbred racing industry have been greatly underestimated because the focus has historically been on incidents that occur on race-days. These findings add to the evidence base for developing strategies to reduce injuries and their associated costs.

    Full Text Available This is a pioneering effort to understand and compare the dynamics of the competitive balance in Turkish First Division basketball and football leagues. Sports leagues need a certain degree of competitive balance in order to survive. If the score of the matches could be predicted before the match times, the overall leagues will become more predictable and won’t be able to maximize the revenue that could be generated from the spectators. Since revenue associated with football leagues is typically greater than with basketball’s in Turkey, one might expect to find greater levels of competitive balance in football than basketball. In this study, the determinants of competitive balance have been argued. The long term impact of competitive balance in sports industry has been investigated. In the analysis part of this study, determining and comparing the path of competitive balance level over a 16 year period of the Turkish First Division Basketball and Football League has been aimed. To this aim, match outcomes for the leagues and C5 Competitive Balance Index and Normalized Herfindahl - Hirschman Index have been used. The findings show that in Footballl Leagues although the competitive balance was converged from time to time, in general a path far from the competitive balance level was followed. In contrast there is an optimal competitive balance level was ccurred in Basketball leagues. We discuss the implications of the empirical results from a sports management perspective and suggest that the major football clubs and the regulatory bodies should develop and support policies towards coexistence and cooperative competition among the other clubs.

    Malone, S, Solan, B, Collins, KD, and Doran, DA. Positional match running performance in elite Gaelic football. J Strength Cond Res 30(8): 2292-2298, 2016-There is currently limited information available on match running performance in Gaelic football. The objective of the current study was to report on the match running profile of elite male Gaelic football and assess positional running performance. In this observational study, 50 elite male Gaelic football players wore 4-Hz global positioning systems units (VX Sports) across 30 competitive games with a total of 215 full game data sets collected. Activity was classed according to total distance, high-speed distance (≥17 km·h), sprint distance (≥22 km·h), mean velocity (km·h), peak velocity (km·h), and number of accelerations. The average match distance was 8,160 ± 1,482 m, reflective of a relative distance of 116 ± 21 m·min, with 1,731 ± 659 m covered at high speed, which is reflective of a relative high-speed distance of 25 ± 9 m·min. The observed sprint distance was 445 ± 169 m distributed across 44 sprint actions. The peak velocity was 30.3 ± 1.8 km·h with a mean velocity of 6.5 ± 1.2 km·h. Players completed 184 ± 40 accelerations, which represent 2.6 ± 0.5 accelerations per minute. There were significant differences between positional groups for both total running distance, high-speed running distance, and sprint distance, with midfielders covering more total and high-speed running distance, compared with other positions (p distance between the first and second half (p middle 3 positions experiencing the highest decrement in performance. The current study is the first to communicate a detailed description of match running performance during competitive elite Gaelic football match play. PMID:26694505

    This supplement contains 16 original articles describing how football conducted as small sided games affects fitness and health of untrained individuals across the lifespan. The intermittent nature of football and high exercise intensity result in a broad range of effects. The heart changes its structure and improves its function. Blood pressure is markedly reduced with the mean arterial blood pressure being lowered by ~10 mmHg for hypertensive men and women training 2-3 times/week for 12-26 weeks. Triglycerides and cholesterol are lowered and body fat declines, especially in middle-aged men and women with type 2 diabetes. Furthermore, muscle mass and bone mineral density increases in a number of participant groups, including 65-75-year-old men. The functional capacity is elevated with increases in VO₂ max of 10-15%, and 50-100% improvements in the capacity to perform intermittent work within 16 weeks. These effects apply irrespective of whether the participants are young, overweight, elderly or suffering from a disease. The studies clearly show that the participants enjoy playing football and form special relationships with their team mates. Thus, football is a healthy activity, providing a unique opportunity to increase recruitment and adherence to physical activity in a hitherto underserved population, and to treat and rehabilitate patients with hypertension, type 2 diabetes and prostate cancer.

    Youth football players may incur hundreds of repetitive head impacts (RHI) in one season. Our recent research suggests that exposure to RHI during a critical neurodevelopmental period prior to age 12 may lead to greater later-life mood, behavioral, and cognitive impairments. Here, we examine the relationship between age of first exposure (AFE) to RHI through tackle football and later-life corpus callosum (CC) microstructure using magnetic resonance diffusion tensor imaging (DTI). Forty retired National Football League (NFL) players, ages 40-65, were matched by age and divided into two groups based on their AFE to tackle football: before age 12 or at age 12 or older. Participants underwent DTI on a 3 Tesla Siemens (TIM-Verio) magnet. The whole CC and five subregions were defined and seeded using deterministic tractography. Dependent measures were fractional anisotropy (FA), trace, axial diffusivity, and radial diffusivity. Results showed that former NFL players in the AFE <12 group had significantly lower FA in anterior three CC regions and higher radial diffusivity in the most anterior CC region than those in the AFE ≥12 group. This is the first study to find a relationship between AFE to RHI and later-life CC microstructure. These results suggest that incurring RHI during critical periods of CC development may disrupt neurodevelopmental processes, including myelination, resulting in altered CC microstructure.

    Multiple playing surfaces and footwear used in American football warrant a better understanding of relationship between different combinations of turf and footwear. The purpose of this study was to examine effects of shoe and stud types on ground reaction force (GRF) and ankle and knee kinematics of a 180° cut and a single-leg 90° land-cut on synthetic turf. Fourteen recreational football players performed five trials of the 180° cut and 90° land-cut in three shoe conditions: non-studded running shoe, and football shoe with natural and synthetic turf studs. Variables were analyzed with a 3 × 2 (shoe × movement) repeated measures analysis of variance (p studs produced smaller peak medial GRFs compared to synthetic turf studs and non-studded shoe (p = 0.012). For land-cut, peak eversion velocity was reduced in running shoes compared to natural (p = 0.016) and synthetic (p = 0.002) turf studs. The 90° land-cut movement resulted in greater peak vertical GRF and loading rate compared to the 180° cut. Overall, increased GRFs in the 90° land-cut movement may increase the chance of injury.

    For performance and injury prevention in sport, core strength and endurance are focused prerequisites. Therefore we evaluated characteristics of trunk muscle activation and performance during strength-endurance related trunk field tests. Strength-endurance ability, as total time to failure, and activation of trunk muscles was measured in 39 football players of the highest German female football league (Bundesliga) (N = 18, age: 20.7 y [SD 4.4]) and the highest national male under-19 league (N = 21, age: 17.9 y [0.7]) in prone plank, side plank, and dorsal position. Maximal isometric force was assessed during trunk extension and flexion, rotation, and lateral flexion to normalize EMG and to compare with the results of strength-endurance tests. For all positions of endurance strength tests, a continuous increase in normalized EMG activation was observed (P females (P = .02). We conclude, that in the applied strength-endurance testing, the activation of trunk muscles was high, especially in females. As high trunk muscle activation can infer fatigue, limb strength can limit performance in prone and side plank position, particularly during high trunk muscle activation. PMID:26671894

    Objectives: Fifty percent of all athletes at the National Football League (NFL) Combine report having had a shoulder injury at some point during their playing career. Rotator cuff tears are rare injuries in young athletes, but an increasing incidence has been noted amongst competitive football players. It is unknown how pre-existing rotator cuff tears affect career longevity and performance of NFL athletes. In Combine athletes with pre-existing rotator cuff tears, knowledge of outcomes may help athletes and physicians manage expectations of draft potential, career length and performance. Methods: The written medical evaluations of prospective professional American football athletes from 2003-2011 during the NFL Combine were compiled and evaluated. All players were evaluated for the diagnosis of a pre-existing rotator cuff tear and stratified based on whether or not they underwent surgical intervention. Athletes with rotator cuff tears, who were selected in the NFL draft, were matched by age, position, year, and round drafted to control draftees without significant documented shoulder pathology. Career statistics, including a previously established “Performance Score,” were compiled. The continuous variables of each cohort were compared using a Student's t-test. A Chi Squared test was performed to analyze the categorical data. Statistical significance was accepted with a p-value < 0.05. Results: Between the years of 2003 and 2011, 2,965 consecutive athletes were evaluated. Forty-nine athletes were identified with a pre-existing rotator cuff tear; twenty-two of these athletes underwent surgical intervention for their tear and 27 were treated non-operatively. Those who attended the NFL Combine with a history of a rotator cuff tear were significantly less likely to be drafted than those without a previous injury (55.1% vs. 77.5% respectively, p = 0.002) (Table 1A). The 27 drafted athletes with pre-existing rotator cuff tears played significantly fewer years (4.3 vs

    Hypopituitarism is common after moderate and severe traumatic brain injury (TBI). Herein, we address the association between mild TBI (mTBI) and pituitary and metabolic function in retired football players. Retirees 30-65 years of age, with one or more years of National Football League (NFL) play and poor quality of life (QoL) based on Short Form 36 (SF-36) Mental Component Score (MCS) were prospectively enrolled. Pituitary hormonal and metabolic syndrome (MetS) testing was performed. Using a glucagon stimulation test, growth hormone deficiency (GHD) was defined with a standard cut point of 3 ng/mL and with a more stringent body mass index (BMI)-adjusted cut point. Subjects with and without hormonal deficiency (HD) were compared in terms of QoL, International Index of Erectile Function (IIEF) scores, metabolic parameters, and football career data. Of 74 subjects, 6 were excluded because of significant non-football-related TBIs. Of the remaining 68 subjects (mean age, 47.3±10.2 years; median NFL years, 5; median NFL concussions, 3; mean BMI, 33.8±6.0), 28 (41.2%) were GHD using a peak GH cutoff of <3 ng/mL. However, with a BMI-adjusted definition of GHD, 13 of 68 (19.1%) were GHD. Using this BMI-adjusted definition, overall HD was found in 16 (23.5%) subjects: 10 (14.7%) with isolated GHD; 3 (4.4%) with isolated hypogonadism; and 3 (4.4%) with both GHD and hypogonadism. Subjects with HD had lower mean scores on the IIEF survey (p=0.016) and trended toward lower scores on the SF-36 MCS (p=0.113). MetS was present in 50% of subjects, including 5 of 6 (83%) with hypogonadism, and 29 of 62 (46.8%) without hypogonadism (p=0.087). Age, BMI, median years in NFL, games played, number of concussions, and acknowledged use of performance-enhancing steroids were similar between HD and non-HD groups. In summary, in this cohort of retired NFL players with poor QoL, 23.5% had HD, including 19% with GHD (using a BMI-adjusted definition), 9% with hypogonadism, and 50% had Met

Minnesota Satisfaction Questionnaire 20 "- Short Form” developed by Weiss et al (1967 and adapted to Turkish by Baycan (1985 was used. SPSS was used for the analysis of the data. Super League football players general job satisfaction levels were significantly higher than 2nd and 3rd division football players. The burnout levels of Super League football players were significantly lower than the others. The occupation burnout and job satisfaction levels of football players have a negative relationship mutually ; while job satisfaction level increased, burnout levels of players reduced. Most remarkable part is that Midfielders have lower external satisfaction than goalkeepers.

    Over the past decade, there has been significant debate regarding the effect of cumulative subconcussive head impacts on short and long-term neurological impairment. This debate remains unresolved, because valid epidemiological estimates of athletes' total contact exposure are lacking. We present a measure to estimate the total hours of contact exposure in football over the majority of an athlete's lifespan. Through a structured oral interview, former football players provided information related to primary position played and participation in games and practice contacts during the pre-season, regular season, and post-season of each year of their high school, college, and professional football careers. Spring football for college was also included. We calculated contact exposure estimates for 64 former football players (n = 32 college football only, n = 32 professional and college football). The head impact exposure estimate (HIEE) discriminated between individuals who stopped after college football, and individuals who played professional football (p < 0.001). The HIEE measure was independent of concussion history (p = 0.82). Estimating total hours of contact exposure may allow for the detection of differences between individuals with variation in subconcussive impacts, regardless of concussion history. This measure is valuable for the surveillance of subconcussive impacts and their associated potential negative effects.

    The present study investigated the performance effects and physiological adaptations over 16 weeks of recreational football training and continuous running for healthy untrained premenopausal women in comparison with an inactive control group [Football group (FG): n=21; running group (RG): n=18; CO: n=14]. Two weekly 1-h training sessions were performed in FG and RG. After 4 and 16 weeks of training VO(2max) was elevated (Pwomen's football leads to significant increases in VO(2max), performance and muscular adaptations throughout a 16-week training period. Thus, football can be used as an activity to elevate the physical capacity of untrained women. PMID:19954496

    Full Text Available In order to prevent anterior cruciate ligament injuries it is necessary to define risk factors and to analyze the most frequent causes of injuries - that being the aim of this study. The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen, 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%, injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%, then in handball players (22%, basketball players (13%, volleyball players (8%, martial arts fighters (4%. However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players. Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%, at landing after the jump or when changing direction of movement (75% without a contact with other competitors, on dry surfaces (79%, among not so well prepared sportsmen.

    With the increased national concern about concussions in football, recent research has focused on evaluating the impact performance of modern football helmets. Specifically, this technical note offers a biomechanical analysis of classic leather helmets compared with modern helmets. Furthermore, modern helmets were examined to illustrate the performance differences between the better- and worse-performing ones. A total of 1224 drop tests were performed from a range of drop heights and impact locations on 11 different helmet types (10 modern and 1 leather helmet model). The resulting head acceleration was used to assess the risk of concussion for each drop test. The results of this analysis demonstrate that modern helmets are significantly and substantially superior to leather helmets in all impact scenarios, and that notable differences exist among modern helmets.
