Abstract
BACKGROUND The incidence of lower extremity injuries in female soccer players is high, but the risk factors for injuries are unknown. PURPOSE To investigate risk factors for lower extremity injuries in elite female soccer players. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Players in the Norwegian elite female soccer league (N = 12 teams) participated in baseline screening tests before the 2009 competitive soccer season. The screening included tests assessing maximal lower extremity strength, dynamic balance, knee valgus angles in a drop-jump landing, knee joint laxity, generalized joint laxity, and foot pronation. Also included was a questionnaire to collect information on demographic data, elite-level experience, and injury history. Time-loss injuries and exposure in training and matches were recorded prospectively in the subsequent soccer season using weekly text messaging. Players reporting an injury were contacted to collect data regarding injury circumstances. Univariate and multivariate regression analyses were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for ±1 standard deviation of change. RESULTS In total, 173 players underwent complete screening tests and registration of injuries and exposure throughout the season. A total of 171 injuries in 107 players (62%) were recorded; ligament and muscle injuries were the most frequent. Multivariate analyses showed that a greater body mass index (BMI) (OR, 1.51; 95% CI, 1.21-1.90; P = .001) was the only factor significantly associated with new lower extremity injuries. A greater BMI was associated with new thigh injuries (OR, 1.51; 95% CI, 1.08-2.11; P = .01), a lower knee valgus angle in a drop-jump landing was associated with new ankle injuries (OR, 0.64; 95% CI, 0.41-1.00; P = .04), and a previous knee injury was associated with new lower leg and foot injuries (OR, 3.57; 95% CI, 1.27-9.99; P = .02), whereas none of the factors investigated influenced the risk of new knee injuries. CONCLUSION A greater BMI was associated with lower extremity injuries in elite female soccer players. CLINICAL RELEVANCE Increased knowledge on risk factors for lower extremity injuries enables more targeted prevention strategies with the aim of reducing injury rates in female soccer players.

Abstract
Background Chronic ankle instability (CAI) is a disabling condition often encountered after ankle injury. Three main components of CAI exist; perceived instability; mechanical instability (increased ankle ligament laxity); and recurrent sprain. Literature evaluating CAI has been heavily focused on adults, with little attention to CAI in children. Hence, the objective of this study was to systematically review the prevalence of CAI in children. Methods Studies were retrieved from major databases from earliest records to March 2013. References from identified articles were also examined. Studies involving participants with CAI, classified by authors as children, were considered for inclusion. Papers investigating traumatic instability or instability arising from fractures were excluded. Two independent examiners undertook all stages of screening, data extraction and methodological quality assessments. Screening discrepancies were resolved by reaching consensus. Results Following the removal of duplicates, 14,263 papers were screened for eligibility against inclusion and exclusion criteria. Nine full papers were included in the review. Symptoms of CAI evaluated included perceived and mechanical ankle instability along with recurrent ankle sprain. In children with a history of ankle sprain, perceived instability was reported in 23-71% whilst mechanical instability was found in 18-47% of children. A history of recurrent ankle sprain was found in 22% of children. Conclusion Due to the long-lasting impacts of CAI, future research into the measurement and incidence of ankle instability in children is recommended.

Abstract
BACKGROUND Female soccer has grown tremendously in the last decade. Studies have suggested that female soccer players are more susceptible to injuries than their male counterparts, and their vulnerability is due mainly to intrinsic factors such as their anatomical and physiological structure. OBJECTIVES To establish factors associated with soccer injuries among first-division Rwandan female soccer players. METHODS In a descriptive cross-sectional study, self-administered questionnaires were used to investigate factors associated with injuries among soccer players. RESULTS Almost half of the 300 participants (45%) indicated having been injured in the three seasons prior to the study. More than half (52.6%) were recurrent injuries. The ankle was the most common body part injured. Intrinsic factors associated with injuries were age, excessive ankle range of motion, pre-menstrual symptoms, and previous injury (p-value < 0.05). Extrinsic factors associated with injuries were use of oral contraceptive pills, (OCP), competition level, use of protective equipment, and player's position. CONCLUSIONS The large number of recurring injuries was notable, emphasizing the importance of prevention strategies and access to adequately trained medical personnel as research has shown a significant reduction in the prevalence of recurring injuries after the introduction of effective prevention programmes.

Abstract
OBJECTIVE To analyse the incidence, characteristics and circumstances of injuries during a female youth amateur football tournament in Kenya. DESIGN 14 injury recorders prospectively registered and classified all injuries during all matches. Four physiotherapists and two doctors supported the injury recorders. SETTING A 2-day Mathare Youth Sports Association (MYSA) inter-provincial football tournament for female players in Nairobi, Kenya. The tournament is organised by a non-governmental organisation (NGO). PARTICIPANTS 938 females divided into three age groups (under 13 years (U13), under 16 years (U16) and over 16 years (O16)). MAIN OUTCOME MEASUREMENTS Overall injury incidence. RESULTS 123 injuries occurred in 106 matches. The incidence of all injuries was 93.3 injuries/1000 h. Players in the U13 (relative risk (RR)=2.16, 95% CI 1.3 to 3.5; p=0.002) and U16 (RR=2.17, 95% CI 1.3 to 3.5; p=0.002) age groups had an increased risk of injury compared to the O16 group. Most injuries allowed the players to continue to play (n=98 of 121; 81%). For 15 (12%) of the injuries the player did not continue to play but was expected to fully participate in the following match, and eight of the injuries (6.1 injuries/1000 h) were expected to result in the player's absence from play for 1-7 days. The injuries most commonly affected the lower limb (n=100; 82%); contusions to the ankle (n=15; 12%) and foot/toe (n=15; 12%) were the most common specific injury types. Most acute injuries (89 of 113, 79%) were caused by player contact. CONCLUSIONS The incidence of injuries among female youth football players in a national tournament in Kenya was high, but time-loss injuries were rare. Playing football in a tournament organised by an NGO at the inter-provincial level was safe.

Abstract
BACKGROUND Football (soccer) is endorsed as a health-promoting physical activity worldwide. When football programs are introduced as part of general health promotion programs, equal access and limitation of pre-participation disparities with regard to injury risk are important. The aim of this study was to explore if disparity with regard to parents' educational level, player body mass index (BMI), and self-reported health are determinants of football injury in community-based football programs, separately or in interaction with age or gender. METHODOLOGY/PRINCIPAL FINDINGS Four community football clubs with 1230 youth players agreed to participate in the cross-sectional study during the 2006 season. The study constructs (parents' educational level, player BMI, and self-reported health) were operationalized into questionnaire items. The 1-year prevalence of football injury was defined as the primary outcome measure. Data were collected via a postal survey and analyzed using a series of hierarchical statistical computations investigating associations with the primary outcome measure and interactions between the study variables. The survey was returned by 827 (67.2%) youth players. The 1-year injury prevalence increased with age. For youths with parents with higher formal education, boys reported more injuries and girls reported fewer injuries than expected; for youths with lower educated parents there was a tendency towards the opposite pattern. Youths reporting injuries had higher standardized BMI compared with youths not reporting injuries. Children not reporting full health were slightly overrepresented among those reporting injuries and underrepresented for those reporting no injury. CONCLUSION Pre-participation disparities in terms of parents' educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. When introduced as a general health promotion, football associations should adjust community-based youth programs to accommodate children and adolescents with increased pre-participation injury risk.

Abstract
Studies regarding ankle and foot overuse injuries are quite diverse in research methodology, data reporting, and outcomes. The aims of this systematic review were to analyze the methodology of published studies regarding ankle and foot overuse injuries in different sports disciplines and to summarize epidemiological data of ankle and foot overuse injuries. Four electronic databases, PubMed (MEDLINE), EMBASE, CINAHL, and SPORTDiscus(®) were systematically searched up to June 2011. A total of 89 articles on 23 sports disciplines were included in this review. Soccer, running, and gymnastics were the most frequently studied sports. Achilles tendinopathy, plantar fasciitis, and stress fracture were the most frequently studied injuries. Study design and reporting methods were heterogeneous. Most studies suffered from a weak methodology and poor reporting. The most common weaknesses were lack of a clear case definition, describing assessment procedures and reporting sample characteristics. Due to methodological heterogeneity of studies, inter-sports and intra-sports comparisons and meta-analysis were not possible. Methodology of most studies on incidence and prevalence of ankle and foot overuse injuries is insufficient. Based on the results, we recommend authors to clearly define cases, describe assessment procedures and report sample characteristics adequately.

Abstract
INTRODUÇÃO: O futsal vem se destacando no cenário internacional como uma das modalidades em maior ascensão. Na literatura, são escassos os estudos que relatam as lesões no gênero feminino nesta modalidade. OBJETIVO: O objetivo deste estudo foi identificar a prevalência de lesões em atletas do futsal feminino brasileiro. MÉTODOS: A amostra correspondeu às atletas que participaram da Liga Nacional de Futsal 2011, totalizando 135 atletas. Investigou-se a prevalência de lesões apresentadas durante toda a temporada de 2010. RESULTADOS: Das 135 atletas, 73 (54,1%) apresentaram algum tipo de lesão, sendo identificados 104 traumas. As lesões nos membros inferiores corresponderam a 86,5% do total, com 28,9% (n = 30) no tornozelo, 24% (n = 25) na coxa e o joelho correspondeu a 23,1% (n = 24). Quanto à forma, 51,9% (n = 54) ocorreram sem contato e 46,1% (n = 48) por contato direto. Durante o treinamento técnico/tático ou treinamento físico ocorreram 59,6% das lesões (n = 62) e 40,4% (n = 42), durante os jogos. Das lesões, 58,6% ocorreram pela primeira vez e 40,4% são recidivas. Não foi encontrada associação entre acompanhamento fisioterapêutico em treinos e competições, com o número e a gravidade das lesões. Também não há relação com o membro dominante e o hemicorpo do trauma. CONCLUSÕES: As atletas do futsal feminino brasileiro apresentam grande prevalência de lesões, principalmente no tornozelo, coxa e joelho, sendo que a maioria delas ocorre nos treinamentos. Lesões que acontecem sem contato com outro adversário prevaleceram em relação aos traumas com contato, fato que se opõe aos demais achados da literatura. O número de primeiras lesões foi maior em relação às recidivas e, quanto à gravidade, prevaleceram as lesões moderadas. Para minimizar o número de lesões, são necessárias estratégias específicas de prevenção, enfatizando os segmentos do tornozelo, joelho e coxa.

Abstract
OBJECTIVES To describe acute injury characteristics in children and youth soccer players and to identify the characteristics of patients who required hospital admission. METHODS The analysis of the study was based on the Canadian Hospitals Injury Reporting and Prevention Program. A total of 32,149 patients (aged 5-19 years) with soccer-related injuries presenting to 16 participating hospital emergency departments from 1994 to 2004 were included in the analysis. RESULTS Males had the highest proportion of injuries (62%). The leading injuries were sprains/strains (38%), followed by fractures/dislocations (31%) and superficial injuries (23%). A total of 896 cases (3%) required hospital admission. Based on logistic regression analysis, being a male, playing unorganized soccer, having multiple body injuries, playing soccer outside school premises, and playing during the summer/fall increased the likelihood of hospital admission. Moreover, having a head/face/neck injury (Odds ratio [OR], 1.3; 95% confidence interval [95% CI], 1.1-1.7) and trunk injury (OR, 1.7; 95% CI, 1.2-2.4) as compared with an upper extremity injury and having injuries from contact with structures/surfaces (OR, 3.1; 95% CI, 2.2-4.3) and with other players (OR, 2.5; 95% CI, 1.8-3.5) as compared with ball contact had the highest odds of hospital admission. CONCLUSIONS Soccer accounted for a significant proportion of injuries presented to Canadian Hospitals Injury Reporting and Prevention Program emergency departments during 1994-2004. Further studies investigating potential interventional programs and techniques among this population are highly warranted.

Abstract
Football (soccer), the most popular sport worldwide, is associated with a high injury risk, and the knee joint is often affected. Several studies have found female players to be more susceptible to knee injury, anterior cruciate ligament (ACL) injury in particular, compared to their male counterparts. There is, however, some controversy regarding the magnitude of this risk increase and a few studies have found no differences. The influence of age and activity type on gender-related differences in injury risk is only scarcely investigated. In this paper, the literature reporting gender-specific ACL injury risk in football is reviewed. A literature search yielded 33 relevant articles that were included for review. These show that female players have a 2-3 times higher ACL injury risk compared to their male counterparts. Females also tend to sustain their ACL injury at a younger age than males, and a limiting factor in the existing literature is that age is not adjusted for in comparisons of ACL injury risk between genders. Furthermore, the risk increase in females is primarily evident during match play, but type of exposure is also rarely adjusted for. Finally, the studies included in this review share important methodological limitations that are discussed as a starting point for future research in the field.

Abstract
BACKGROUND Few descriptive epidemiologic studies of injury in soccer are of community-level players. Although many sports injury surveillance systems have been described in the scientific literature, only 1 has been implemented in community-level soccer and that was restricted to adolescent players in a single club. PURPOSE The objective of this study was to develop a method for undertaking routine surveillance of injury in community-level soccer. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A cohort of 880 community-level players aged 13 years and over was followed over 1 winter competitive season. Each week, each player was contacted by telephone and an interview conducted to collect data on participation in matches and training sessions, injuries, and adherence to injury prevention measures. RESULTS Seventy-five percent (n = 510) of the cohort was male and the median age was 16 years. Data were collected on 11 268 player-matches totaling 13 483 player-match hours and 11 540 player-training sessions totaling 16 031 player-training hours. A total of 677 match injury events were reported, giving overall incidence rates of 50.2 injury events per 1000 player-match hours and 6.0 injury events per 100 player-matches. The incidence rate for match injury events was significantly higher for females than for males (63.9 vs 46.9). A total of 145 training injury events were reported, giving overall incidence rates of 9.0 injury events per 1000 player-training hours and 1.3 injury events per 100 player-training sessions. The most common injuries were sprains and strains of the lower limb, and tackling was the most common cause of injury. CONCLUSION This study has shown that routine injury surveillance, using a cohort design with exposure measurement, can be successfully implemented in community-level soccer.

Abstract
Lower extremity musculoskeletal pain is a common complaint in the adolescent athlete. During rapid growth, several common biomechanical changes occur that may predispose to overuse injury. Unlike fractures, most of these office-based sports medicine complaints are initially evaluated by the primary care provider. This review discusses several of the most common complaints and briefly discusses some clinically significant conditions that masquerade as common injuries. The article discusses only the injuries unique to the growing athlete. The article's goal is to help develop a framework for the pediatric clinician to evaluate common complaints and formulate a plan that includes simple stretches and physical therapy recommendations.

Abstract
OBJECTIVE To obtain precise information on injury patterns in the women's premier soccer league in Germany. DESIGN One-year, prospective, epidemiologic cohort study. SETTING Institutional level German Football Association. PARTICIPANTS All 254 players from all 12 women's premier league teams were included. INTERVENTIONS Base information by standardized personal interviews. Evaluation of all injury-associated medical data transmitted by standardized documentation forms. ASSESSMENT OF RISK FACTORS Injuries incidence rates (average, 95% confidence intervals) based on the exposure in matches and at practice. MAIN OUTCOME MEASURES All time loss diagnoses, number and context of injuries related to their anatomical localization, severity, and rehabilitation period were recorded. RESULTS All 254 players finished the study [average age, 22.8 years (16-35 years)]. Two hundred forty-six injuries amounted to an injury rate of 3.3 per 1000 hours (games, 18.5 per 1000 hours; practice, 1.4 per 1000 hours). Injury distribution: knee, 31.0%; ankle, 22.1%; thigh, 12.9%; and head, 7.1%. The seasonal peak was at the beginning of the competitive season. Injury rates doubled after the 60th minute. Twenty-nine percent of the injuries were severe, and 37% were moderate. CONCLUSIONS Female players suffer a high amount of head injuries and severe knee and ankle injuries. The most common single injury is a sprained ankle. Torn ligaments in the ankle and knee are the most common injuries that require a long recovery period. Most of the severe injuries (>30 days) are due to noncontact intrinsic mechanisms. Almost one-quarter of all injuries consist of exertion syndromes not yet correlated with certain seasonal periods.

Abstract
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.

Abstract
Hip dislocations during sporting activities represent only 2%-5% of all hip dislocations. Most hip dislocations in sports can be categorised as "less complicated traumatic hip dislocations" by the Stewart-Milford classification due to the fact that minimal force is involved. The incidence of avascular necrosis of the femoral head greatly increases if the time to reduction is more than six hours. We report the case of a 38-year-old football player who suffered hip dislocation while kicking the ball with the medial aspect of the right foot in an external rotated manner of the right hip. Closed reduction was performed within 2 hours; postoperative follow-up was uneventful. Six months later the patient is out of any complaints; there is no sign of AVN of the femoral head.

Abstract
Injury rates in youth soccer, known as football outside the United States, are higher than in many other contact/collision sports and have greater relative numbers in younger, preadolescent players. With regard to musculoskeletal injuries, young females tend to suffer more knee injuries, and young males suffer more ankle injuries. Concussions are fairly prevalent in soccer as a result of contact/collision rather than purposeful attempts at heading the ball. Appropriate rule enforcement and emphasis on safe play can reduce the risk of soccer-related injuries. This report serves as a basis for encouraging safe participation in soccer for children and adolescents.

Abstract
All 12 female football clubs (228 players) and 11 of 14 male clubs (239 players) in the Swedish premier league were followed prospectively during the 2005 season. Individual exposure (playing time), injuries (time loss), and injury severity (days lost due to injury) were recorded by the team medical staffs. Injury incidence was higher for male players during both training (4.7 vs 3.8 injuries/1000 h, P=0.018) and match play (28.1 vs 16.1, P<0.001). However, no difference was found in the incidence of severe injury (absence >4 weeks) (0.7/1000 h in both groups). The thigh, especially the hamstrings, was the overall most commonly injured region in both sexes, while the hip/groin was more commonly injured in male players and the knee in female players. Knee ligament injuries accounted for 31% and 37% of the total time lost from football for male and female players, respectively. In conclusion, male elite players had a higher injury incidence than their female counterparts although no difference was observed in the incidence of moderate to severe injury. We recommend that preventive measures should be focused on hamstring and knee ligament injury in order to reduce the overall injury burden.

Abstract
BACKGROUND The injury rate in soccer is high, and studies have shown that the injury rate among players aged 16 years or older approaches that of adult players. However, little is known about the injury risk among the youngest players, that is, players between 6 and 12 years. PURPOSE To examine the risk of injuries in children 6 to 16 years old playing organized soccer. STUDY DESIGN Descriptive epidemiological study. METHODS Injuries were recorded prospectively throughout 1 season among 121 soccer teams (1879 players, aged 6-16 years) from 2 communities in the southeastern part of Norway. RESULTS A total of 159 players sustained 200 injuries, corresponding to an overall injury incidence of 2.2 per 1000 playing hours (95% confidence interval, 1.8-2.6) among boys and 2.0 injuries per 1000 hours (95% confidence interval, 1.4-2.5) among girls. The overall injury incidence was significantly higher (relative risk, 1.7; 95% confidence interval, 1.3-2.2) among older players (13-16 years; 2.6 injuries per 1000 hours, 95% confidence interval, 2.2-3.0) than among younger players (6-12 years; 1.6 injuries per 1000 hours, 95% confidence interval, 1.2-1.9). The injuries recorded in the youngest group were few and mainly mild. CONCLUSION The injury risk among young players (6-12 years) playing organized 5- or 7-a-side soccer is low, lower than that of adolescents and much lower than at the elite level. Soccer is a safe sport for children.

Abstract
Identifying and understanding injury risk factors are necessary to target the injury-prone athlete and develop injury prevention measurements. The influence of psychological factors on injuries in football is poorly documented. The purpose of this 8-month prospective cohort study therefore was to examine whether psychological player characteristics assessed by a self-administered questionnaire represent risk factors for injury. At baseline, female football players (14-16 years) were asked to complete a detailed questionnaire covering player history, previous injuries, perception of success and motivational climate, life stress, anxiety and coping strategies. During the 2005 season, a total of 1430 players were followed up to record injuries. A history of a previous injury [odds ratio (OR)=1.9 (1.4; 2.5), P<0.001] increased the risk of a new injury to the same region. There were significant differences in disfavor for previously injured compared with non-injured players for ego orientation (P=0.007), perception of a performance climate (P=0.003) and experienced stressful life events (P<0.001). However, only high life stress (P=0.001) and perception of a mastery climate (P=0.03) were significant risk factors for new injuries. In conclusion, a perceived mastery climate and a high level of life stress were significant predictors for new injuries in a cohort of young female football players.

Abstract
BACKGROUND Sports injuries in young athletes are a public health issue which deserves special attention. Effective prevention can be achieved with training programmes originating from the field of physical therapy and medicine. SOURCES OF DATA A systematic literature search on injury prevention in youth sport was performed in the MEDLINE database. AREAS OF AGREEMENT For prevention programmes to reduce sports injuries, critical factors must be considered, such as training content, duration and frequency, as well as athlete compliance. AREAS OF CONTROVERSY Home-based programmes could be inferior to supervised training, but are efficient if compliance is high. So far prevention programmes have focused on team sports and their efficiency in individual sports remains to be proven. GROWING POINTS Active prevention programmes focusing specifically on the upper extremity are scarce. Initiatives enhancing the awareness of trainers, athletes and therapists about risk factors and systematic prevention measures should be encouraged.

Abstract
OBJECTIVE To examine the effect of a comprehensive warm-up programme designed to reduce the risk of injuries in female youth football. DESIGN Cluster randomised controlled trial with clubs as the unit of randomisation. SETTING 125 football clubs from the south, east, and middle of Norway (65 clusters in the intervention group; 60 in the control group) followed for one league season (eight months). PARTICIPANTS 1892 female players aged 13-17 (1055 players in the intervention group; 837 players in the control group). INTERVENTION A comprehensive warm-up programme to improve strength, awareness, and neuromuscular control during static and dynamic movements. MAIN OUTCOME MEASURE Injuries to the lower extremity (foot, ankle, lower leg, knee, thigh, groin, and hip). RESULTS During one season, 264 players had relevant injuries: 121 players in the intervention group and 143 in the control group (rate ratio 0.71, 95% confidence interval 0.49 to 1.03). In the intervention group there was a significantly lower risk of injuries overall (0.68, 0.48 to 0.98), overuse injuries (0.47, 0.26 to 0.85), and severe injuries (0.55, 0.36 to 0.83). CONCLUSION Though the primary outcome of reduction in lower extremity injury did not reach significance, the risk of severe injuries, overuse injuries, and injuries overall was reduced. This indicates that a structured warm-up programme can prevent injuries in young female football players. TRIAL REGISTRATION ISRCTN10306290.

Abstract
BACKGROUND Identifying and understanding injury risk factors are necessary to develop and target measures to prevent injuries. Because youth teams rarely have health care professionals working directly with the team, identifying players at increased risk through elaborate clinical tests is not feasible. Questionnaires may be a possible alternative as screening instruments. PURPOSE To examine whether injury history and lower limb function assessed by a self-administered questionnaire represent risk factors for injury. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS At baseline, female soccer players (aged 14-16 years) were asked to complete a detailed questionnaire covering sports participation; history of previous injuries to the ankle, knee, hamstring, or groin; as well as present function of these 4 specific regions. A total of 1430 (71% of the entire cohort) were followed up to record injuries during the subsequent 8 months. RESULTS A history of a previous injury to the ankle (rate ratio, 1.2 [1.1-1.3]; P < .001), knee (rate ratio, 1.4 [1.2-1.6]; P <.001), or groin (rate ratio, 1.6 [1.2-2.1]; P = .004) increased the risk of new injuries to the same region. Reporting a reduced function (defined as <80% of the maximum score) for the ankle (rate ratio, 1.7 [1.1-2.7]; P =.021) or knee (rate ratio, 3.2 [1.8-5.7]; P <.001) was also a significant risk factor. However, the sensitivity of previous injuries and lower limb function in predicting new injuries was low. CONCLUSION A history of previous injury and reduced function at baseline were significant risk factors for new injuries to the same region during the following season.

Abstract
The epidemiology of sports injuries in children and youth is an important area of research that has been largely overlooked in the medical and sport science literature. This article presents an overview of the analytic aspects of pediatric sports injury epidemiology, focusing on injury risk factors and preventive measures. The review indicates that few modifiable injury risk factors have been statistically evaluated, and not many studies have been designed to determine the effect of injury prevention measures in pediatric sports. However, initial results are promising. Specific directions for further analytic research are presented.

Abstract
Female soccer has become increasingly popular during the last two decades. According to the International Football Association (FIFA) there are approximately 40 million registered female soccer players in the world. Three studies in elite soccer have shown an injury incidence during games ranging from 12.6 to 23.3 injuries per 1,000 h. A very high incidence of ACL-injuries ranging from 0.31 to 2.2 per 1,000 game hours has also been shown. We followed the Norwegian female elite series during the 2001 season to estimate the incidence and characteristics of injuries. A total of 181 female soccer players on ten teams were followed during the 2001 elite season in Norway. We recorded baseline data, match and training exposure and injury data as type of injury, location and severity of injury. The mean age of the players was 23 years (range 17-34). A total of 189 injuries were recorded and 19 (10%) of these were overuse injuries; 89 (47%) occurred during games and 100 (53%) during training sessions. The incidence of acute injuries was 23.6 per 1,000 game hours and 3.1 per 1,000 training hours. The majority of the injuries occurred in the lower extremities (81%), but there were also a significant number of head injuries (6.3%). The most common injury type was ankle sprain (17.2%). Half of the injuries were minor, with training or game absence of less than 7 days. Midfielders sustained the most injuries (32.6%) with an incidence of 42.4 per 1,000 game hours. We recorded two ACL-injuries and two PCL-injuries during the season. They all occurred during games, and the incidence was therefore calculated to 0.6 per 1,000 game hours for both injury types. The incidences of injuries reported for female soccer varies considerably, with the highest numbers reported from Germany and the present study. These studies have also the highest incidence of minor injuries registered. The location of the injuries is quite similar compared to other reports, but the number of ankle sprains seems to be higher in our study, whereas the number of knee and thigh injuries is lower. There has been much attention to ACL injuries in team handball and hamstring injuries in soccer in Norway, and this could have influenced the team's pre-season training, resulting in a reduction in the incidence of these injury types. The high number of ankle injuries has to be addressed to see whether this is a result of inadequate rehabilitation routines leading to re-injuries, or other factors. The high number of ACL-injuries in these reports is alarming and needs special attention in the future.

Abstract
BACKGROUND Epidemiologic data on injuries in young female soccer players at elite levels are scarce. PURPOSE The aim of the present study is to investigate the incidence of soccer-related injuries in young elite female French players. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Injuries sustained by players between 15 and 19 years of age, during 8 seasons, were diagnosed and documented by a sports physician according to type, location, severity, the date the injury occurred, and playing position. RESULTS Altogether 619 injuries were documented for 110 players (92.4%). Of these injuries, 64.6% (4.6/1000 training hours; 95% confidence interval [CI], 4.2-5.0) and 35.4% (22.4/1000 match hours; 95% CI, 19.4-25.4) were sustained during training and matches, respectively. The risk of injury was greater in the youngest (under age 15) group compared with the oldest (under 19) group (relative risk 1.7; 95% CI, 1.3-2.3). Traumatic injuries amounted to 536 (86.4%) and 83 (13.4%) were overuse injuries. There were 51.9% minor injuries, 35.7% moderate injuries, and 12.4% major injuries. Most injuries were located at the lower extremities (83.4%), with the majority affecting the ankle (n = 157). The most commonly diagnosed injury was ankle sprain (16.8%). Twelve anterior cruciate ligament ruptures were sustained, with the majority occurring during matches (n = 10; 1.0/1000 match hours; 95% CI, 0.4-1.6). Reinjuries accounted for 4.4% of total injuries, and September was the predominant month for injury (14.2%). CONCLUSIONS The results, when compared with those of other investigations on female soccer players, revealed high rates of both traumatic injury and match injury, whereas recurrence of injury was low. Injuries, notably sprains, to the ankle were common, suggesting a need for the implementation of specific injury prevention strategies for this joint.

Abstract
Injuries caused by sports and other forms of physical activity in young children constitute a significant public health burden. It is important to quantify this risk to ensure that the benefits of sport participation are not outweighed by the potential harms. This review summarises the literature reporting exposure-based injury rates for various forms of physical activity in children aged 15 years and younger. Forty eight studies were found, of which 27 reported injury rates per hourly based exposure measured and 21 reported injury rates according to some other measure. Fourteen different sports and activities were covered, mostly team ball sports, with soccer being the most widely studied. Injury definition and the method of ascertaining and measuring injuries differed between studies, which created a large variation in reported injury rates that did not necessarily represent actual differences in injury risk between activities. The highest hourly based injury rates were reported for ice hockey, and the lowest were for soccer, although the range of injury rates for both of these activities was wide. Very few studies have investigated sports-related injuries in children younger than 8 years or in unorganised sports situations.

Abstract
Although all injuries in sports are a concern for participants, head injuries are particularly troublesome because of the potential for long-term cognitive deficits. To prevent any specific injury, it is important to understand the basic frequency and incidence of injury and then the mechanism of injury. Once these are established, prevention programmes can be tested to see if the rate of injury changes. A primary problem with head injuries is recognising that the injury has occurred. Many athletes are not aware of the seriousness of concussive injury, thus this type of injury is probably under-reported. Once the diagnosis of a concussion is made, the next difficult decision is when to return a player to the game. These two management issues dominate the continuing development of understanding of concussive head injury. This paper explores the known gender differences between head injuries and highlights the areas that need to be considered in future research.

Abstract
BACKGROUND Despite the growing popularity of women's football and the increasing number of female players, there has been little research on injuries sustained by female football players. PURPOSE Analysis of the incidence, characteristics and circumstances of injury in elite female football players in top-level international tournaments. STUDY DESIGN Prospective survey. METHODS Injuries incurred in seven international football tournaments were analysed using an established injury report system. Doctors of all participating teams reported all injuries after each match on a standardised injury reporting form. The mean response rate was 95%. RESULTS 387 injuries were reported from 174 matches, equivalent to an incidence of 67.4 injuries/1000 player hours (95% CI 60.7 to 74.1) or 2.2 injuries/match (95% CI 2.0 to 2.4). Most injuries (84%; 317/378) were caused by contact with another player. The injuries most commonly involved the lower extremity (n = 248; 65%), followed by injuries of the head and neck (n = 67, 18%), trunk (n = 33, 9%) and upper extremity (n = 32, 8%). Contusions (n = 166; 45%) were the most frequent type of injury, followed by sprains or ligament rupture (n = 96; 26%) and strains or muscle fibre ruptures (n = 31; 8%). The most common diagnosis was an ankle sprain. There were 7 ligament ruptures and 15 sprains of the knee. On average 1 injury/match (95% CI 0.8 to 1.2) was expected to result in absence from a match or training. CONCLUSION The injury rate in women's top-level tournaments was within the range reported previously for match injuries in elite male and female players. However, the diagnoses and mechanisms of injury among the female players differed substantially from those previously reported in male football players.

Abstract
BACKGROUND Analyses of tackle parameters in injury situations have provided valuable information regarding men's football. However, there are no similar data for women's football. OBJECTIVE To categorise the tackle mechanisms leading to injury in elite women's football. STUDY DESIGN Retrospective video analysis of injury situations. METHODS Events associated with all reported injuries during six women's top-level tournaments were analysed on video recordings for tackle parameters. RESULTS More than half of all injuries were due to tackles from the side (52%, 103/200), whereas tackles from behind were much less commonly involved in injury situations (11%, 21/200). One-footed (65%, 130/200) and upper body (21%, 42/200) tackle actions were most common. Sliding-in tackles leading to injury were the least likely to be sanctioned by match referees. Tackling players (45%, 90/200) were almost as likely to be injured as the tackled player (55%). CONCLUSION The present study found differences between injury mechanisms in women's football and previously published data on men's football. Further research, especially using video analysis, is needed for a better understanding of risk situations in football.

Abstract
BACKGROUND Artificial turf is becoming increasingly popular, although the risk of injury on newer generations of turf is unknown. AIM To investigate the risk of injury on artificial turf compared with natural grass among young female football players. STUDY DESIGN Prospective cohort study. METHODS 2020 players from 109 teams (mean (SD) 15.4 (0.8) years) participated in the study during the 2005 football season. Time-loss injuries and exposure data on different types of turf were recorded over an eight-month period. RESULTS 421 (21%) players sustained 526 injuries, leading to an injury incidence of 3.7/1000 playing hours (95% CI 3.4 to 4.0). The incidence of acute injuries on artificial turf and grass did not differ significantly with respect to match injuries (rate ratio (RR) 1.0, 95% CI 0.8 to 1.3; p = 0.72) or training injuries (RR 1.0, 95% CI 0.6 to 1.5, p = 0.93). In matches, the incidence of serious injuries was significantly higher on artificial turf (RR 2.0, 95% CI 1.3 to 3.2; p = 0.03). Ankle sprain was the most common type of injury (34% of all acute injuries), and there was a trend towards more ankle sprains on artificial turf than on grass (RR 1.5, 95% CI 1.0 to 2.2; p = 0.06). CONCLUSION In the present study among young female football players, the overall risk of acute injuries was similar between artificial turf and natural grass.

Abstract
This article systematically reviews epidemiological studies on sports injury from 1977 to 2005 in which ankle injury was included. A total of 227 studies reporting injury pattern in 70 sports from 38 countries were included. A total of 201,600 patients were included, with 32,509 ankle injuries. Ankle injury information was available from 14,098 patients, with 11 847 ankle sprains. Results show that the ankle was the most common injured body site in 24 of 70 included sports, especially in aeroball, wall climbing, indoor volleyball, mountaineering, netball and field events in track and field. Ankle sprain was the major ankle injury in 33 of 43 sports, especially in Australian football, field hockey, handball, orienteering, scooter and squash. In sports injuries throughout the countries studied, the ankle was the second most common injured body site after the knee, and ankle sprain was the most common type of ankle injury. The incidence of ankle injury and ankle sprain was high in court games and team sports, such as rugby, soccer, volleyball, handball and basketball. This systematic review provides a summary of the epidemiology of ankle injury in sports.

Abstract
Injury occurrence in all 12 female elite senior football teams in premiere league was registered during 1 year. Of 269 players, 129 (48%) sustained 237 injuries. The total injury incidence was 4.6/1000 h of football. The injury incidence during practice was 2.7 and during the game time was 13.9/1000 h. The highest injury incidence during practice was to the knee (0.8/1000 h) and thigh (0.5/1000 h), and during game time was to the knee (4.4/1000 h) and head (2.2/1000 h). In total, the location for the highest injury incidence was the knee with 1.5 injuries/1000 h of football. The majority of injuries (82%) were localized to the lower extremities. Sixty-six injuries (28%) were re-occurring injuries (re-injuries). The incidence of traumatic injuries was 3.3/1000 h of football and for overuse injuries 1.3/1000 h. Overuse injuries occurred mainly during the preseason and at the beginning of the spring season. Thirty-nine percent of the injuries were slight or minor causing absence from practice or game time of less than 1 week, 39% were moderate (absence 7-28 days) and 22% were major (absence more than 28 days). The major injuries occurred often owing to trauma and were mainly to the knee.

Abstract
The purpose of this study was to examine the prevalence of injury and the extent of preventive actions in elite Swedish volleyball players. Injuries to players in the elite male and female Swedish division, during the 2002-2003 season, were registered by using a questionnaire. Of the 158 volleyball players (70% response rate), a total of 82 players (52%) reported 121 injuries, during a total exposure time of 24 632 h, representing an overall incidence of 0.77 injuries per player. The majority of the injuries were located in the ankle (23%), followed by the knee (18%) and the back (15%). Most injuries (62%) were classified as being of minor severity. Most injuries occurred during training (47%), and 41% of the injuries had a gradual onset. Fifty-four percent of the injuries that could be related to a specific court situation occurred during blocking, and 30% during spiking. Most players (96%) participated in injury prevention training of some kind, generally performed without supervision (58%). Although most players took part in some kind of preventive action, one out of two players incurred an injury during the season, which indicates that the risk of suffering an injury in elite volleyball is relatively high.

Abstract
OBJECTIVE To provide a critical review of the available literature on the descriptive epidemiology of pediatric sport-related injuries. DATA SOURCES MEDLINE (1966 to 2006) and SPORTDiscus (1975 to 2006) were searched to identify potentially relevant articles. A combination of medical subject headings and text words was used (epidemiology, children, adolescents, athletic injuries, sports, injury, and injuries). Additional references from the bibliographies of retrieved articles were also reviewed. STUDY SELECTION Published research reports on the incidence and distribution of injury in children's and youth sports. Specific emphasis was placed on reviewing original studies, which report incidence rates (rate of injuries per unit athlete time). Forty-nine studies were selected for this review. DATA EXTRACTION Data summarized include incidence of injury relative to who is affected by injury (sport, participation level, gender, and player position), where injury occurs (anatomical and environmental location), when injury occurs (injury onset and chronometry), and injury outcome (injury type, time loss, clinical outcome, and economic cost). DATA SYNTHESIS There is little epidemiological data on injuries for some pediatric sports. Many of the studies retrieved were characterized by methodological short-comings and study differences that limit interpretation and comparison of findings across studies. Notwithstanding, the studies reviewed are encouraging and injury patterns that should be studied further with more rigorous study designs to confirm original findings and to probe causes of injury and the effectiveness of preventive measures. CONCLUSIONS Incidence and severity of injury are high in some child and youth sports. This review will assist in targeting the relevant groups and in designing future research on the epidemiology of pediatric sports injuries. Well-designed descriptive and analytical studies are needed to identify the public health impact of pediatric sport injury.

Abstract
BACKGROUND There are limited data on the epidemiology of indoor soccer injuries. PURPOSE Injury rates and risk factors for injury in adolescent indoor and outdoor soccer in the same cohort of players will be identified and compared. STUDY DESIGN Cohort study (prevalence); Level of evidence, 2. METHODS The study population was a random sample of 21 adolescent (ages 13-17 years) outdoor soccer teams (N = 317). The subcohort included players continuing to play in the indoor soccer season (n = 142). The injury definition included any injury occurring in soccer that resulted in medical attention, the inability to complete a session, and/or missing a subsequent session. RESULTS The overall injury rate found in indoor soccer over 20 weeks was 4.45 injuries per 1000 player hours (95% confidence interval, 3.1-6.19). The overall injury rate found in the 13-week outdoor soccer season among a similar cohort was 5.59 injuries per 1000 player hours (95% confidence interval, 4.42-6.97). The relative risk of injury suggests that there was no significant difference between injury rates by age group or gender in indoor soccer compared with outdoor soccer. The risk of injury in the most elite division of play was greater in outdoor compared with indoor soccer (relative risk, 3.22; 95% confidence interval, 1.8-6.12). The most commonly injured body part in both indoor and outdoor soccer was the ankle, followed by the groin in indoor and the knee in outdoor soccer. CONCLUSION There were no significant differences in overall injury rates found by gender or age group for indoor compared with outdoor soccer. Future research should focus on injury prevention strategies to reduce lower extremity injury in indoor and outdoor adolescent soccer.

Abstract
INTRODUÇÃO: Vários autores têm investigado a incidência de lesões no futebol. Entretanto, poucos trabalhos têm analisado as lesões no Futebol de Salão. O objetivo deste estudo foi analisar a incidência, circunstâncias e características das lesões registradas no Futebol de Salão durante o XV Campeonato Brasileiro de Futebol de Salão Sub 20. MÉTODOS: Fisioterapeutas ou médicos de todas as seleções participantes do XV Campeonato Brasileiro de Futebol de Salão Sub 20 responderam a um questionário para investigar a ocorrência de lesões durante as partidas. A taxa de resposta foi de 100%. RESULTADOS: Um total de 32 lesões foi registrado durante as 23 partidas, com incidência de 1,39 lesão por partida ou 208,6 lesões por 1.000 horas/jogo. Aproximadamente 1 a 3 lesões por partida resultaram em afastamento de jogadores em partidas ou treinamentos. As lesões de contato eram predominantes em 65,62% (21 das 32 lesões) e a maioria dessas lesões não resultou no afastamento dos jogadores. CONCLUSÕES: O presente estudo observou que a incidência das lesões durante o XV Campeonato Brasileiro de Futebol de Salão Sub 20 foi semelhante à registrada em torneios de Futebol de Salão, mas superior aos achados em torneios de futebol, caracterizando a especificidade do esporte. Entretanto, circunstâncias e características são similares entre eles devido à semelhança de demanda do esporte.

Abstract
Data obtained from epidemiological studies of sports injuries are an essential requirement for developing injury prevention, treatment and rehabilitation strategies. Although many authors have discussed the strengths and weaknesses of research methods employed in epidemiology, the potential effects that variations in research design and methods of analysis can have on study conclusions have not been clearly illustrated. This article addresses a number of methodological issues and illustrates their potential effects using examples based on injury data obtained from a single, large epidemiological study in professional rugby union. The examples demonstrate that conflicting conclusions can be reached depending on how the data are collected and analysed. The pivotal roles played by injury definition (loss-of-time, missed matches, diagnostic assessment and surgery), recurrent injury definition (clinical judgement and same injury/same location/same season), method of reporting injuries (number, proportions and incidence) and method of calculating incidence (injuries per 1000 player-hours, per 1000 athlete-exposures and per 1000 matches) are highlighted and illustrated. Other examples show that if training and match injuries are combined, the incidence of injury is more likely to reflect the incidence of training injuries but the distributions of injuries are more likely to reflect the distributions of match injuries. An example is presented that demonstrates that the identification of injuries causing the greatest concern within a sport depends on whether the assessment is based on injury incidence, severity or risk. Finally, examples are presented to show that the relationships identified between sports injuries and risk factors may be dependent on whether case-control or cohort study designs are used. Although there are no simple solutions available to resolve the issues raised, the discussion demonstrates the importance, at least within a sport, of reaching consensus agreements on acceptable study designs and methods of data analysis in sports epidemiology.

Abstract
BACKGROUND There are limited data on the epidemiology of adolescent soccer injury across all levels of play. HYPOTHESIS Through implementation and validation of an injury surveillance system in adolescent soccer, risk factors for injury will be identified. STUDY DESIGN Descriptive epidemiology study. METHODS The study population was a random sample of 21 adolescent soccer teams (ages 12-18). A certified athletic therapist completed preseason baseline measurements and did weekly assessments of any identified soccer injury. The injury definition included any injury occurring in soccer that resulted in 1 or more of the following: medical attention, the inability to complete a session, or missing a subsequent session. RESULTS Based on completeness of data in addition to validity of time loss, this method of surveillance has proven to be effective. The overall injury rate during the regular season was 5.59 injuries per 1,000 player hours (95% confidence interval, 4.42-6.97). Soccer injury resulted in time loss from soccer for 86.9% of the injured players. Ankle and knee injuries were the most common injuries reported. Direct contact was reported to be involved in 46.2% of all injuries. There was an increased risk of injury associated with games versus practices (relative risk = 2.89; 95% confidence interval, 1.69-5.21). The risk of injury in the under 14 age group was greatest in the most elite division. Having had a previous injury in the past 1 year increased the risk of injury (relative risk = 1.74; 95% confidence interval, 1.0-3.1). CONCLUSION There were significant differences in injury rates found by division, previous injury, and session type (practice vs game). Future research should include the use of such a surveillance system to examine prevention strategies for injury in adolescent soccer.

Abstract
BACKGROUND In contrast to the high number of studies about soccer injuries in men, epidemiologic data in high-level female soccer players are scarce. PURPOSE Analysis of injury incidence in elite female soccer players. STUDY DESIGN Descriptive epidemiology study. METHODS There were 165 female soccer players (age, 22.4 +/- 5.0 years) from 9 teams competing in the German national league, who were followed for one complete outdoor season. Their trainers documented the exposure to soccer on a weekly basis for each player, and the team physical therapists reported all injuries with regard to location, type, and circumstances of occurrence. An injury was defined as any physical complaint associated with soccer that limited sports participation for at least 1 day. RESULTS There were 241 injuries sustained by 115 players (70%) reported; 39 injuries (16%) were owing to overuse, and 202 injuries (84%) were traumatic. Overall, 42% of the traumatic injuries occurred during training (2.8/1000 hours of training; 95% confidence interval, 2.2-3.4) and 58% during matches (23.3/1000 match hours; 95% confidence interval, 19.1-27.5); 102 of the traumatic injuries were caused by a contact situation, whereas 95 occurred without any contact. Most injuries (80%) were located at the lower extremities, concerning mainly the thigh (n = 44), knee (n = 45), and ankle (n = 43). Ankle sprain (n = 37) was the most often diagnosed injury. There were 51% minor injuries, 36% moderate injuries, and 13% major injuries. Eleven anterior cruciate ligament ruptures were observed during the season. CONCLUSION The results revealed a high injury incidence rate in games as well as a comparably low incidence rate during training. An important finding of this investigation was the frequent occurrence of anterior cruciate ligament ruptures. Preventive measures should thus focus on the high prevalence of anterior cruciate ligament tears, mostly occurring in noncontact situations.

Abstract
OBJECTIVE The injury data from the first two seasons of the Women's United Soccer Association (WUSA) were analysed to determine the injury incidence, anatomic location of injuries, and relation of player position. METHODS Injury data on 202 players from eight teams during the first two seasons of the WUSA were prospectively collected and analysed. RESULTS A total of 173 injuries occurred in 110 players with an overall injury incidence rate of 1.93 injuries per 1000 player hours. The incidence of injury during practice and games was 1.17 and 12.63 per 1000 player hours, respectively. Of the injuries 82% were acute and 16% were chronic. Most of the injuries (60%) were located in the lower extremities. Strains (30.7%), sprains (19.1%), contusions (16.2%), and fractures (11.6%) were the most common diagnoses and the knee (31.8%) and head (10.9%) were the most common sites of injury. Anterior cruciate ligament (ACL) injuries accounted for 4.6% of all injuries and the incidence of ACL tears was 0.09 per 1000 player hours (practice 0.04, game 0.90). Midfielders suffered the most injuries (p<0.007). CONCLUSION We conclude that the injury incidence in the WUSA is lower than the 6.2 injuries per 1000 player hours found in the corresponding male professional league (Major League Soccer); however, knee injuries predominate even in these elite female athletes.

Abstract
Women's soccer participation is becoming a trend in sport. With increasing number of licensed female soccer players, there is also an increase in sport specific injuries. This fact has socioeconomic importance. The larger pelvic bone leading to an increased internal rotation of the femur, the narrower intercondylar notch as well as the unfavorable strength ratio of the hamstrings vs. the quadriceps muscle lead to an increased risk for injuries of the anterior cruciate ligament in female soccer.Several studies showed that intervention programs based on neuromuscular or proprioceptive training or intensive strengthening of the hamstrings can reduce the incidence of injuries. Moreover, the importance of sufficient rehabilitation after injuries has to be emphasized, as the reoccurrence of injury is high.

Abstract
Several investigators have studied the incidence and causes of soccer injuries in male professional players; however, epidemiological data on injuries in female soccer players are limited. From the data presented, it can be estimated that, on average, every elite male soccer player incurs approximately one performance-limiting injury each year. Nine studies on the prevention of soccer injuries were found in the literature. There is some evidence that multi-modal intervention programmes result in a general reduction in injuries. Ankle sprains can be prevented by external ankle supports and proprioceptive/coordination training, especially in athletes with previous ankle sprains. With regard to severe knee injuries, the results of prevention studies are partly inconclusive; however, training of neuromuscular and proprioceptive performance as well as improvement of jumping and landing technique seem to decrease the incidence of anterior cruciate ligament injuries in female athletes. Prevention programmes are likely to be more effective in groups with an increased risk of injury. More methodologically well-designed studies are required to evaluate the effects of specific preventive interventions.

Abstract
The number of people participating in sports continues to increase. The relationship between sports participation, joint injury, and subsequent osteoarthritis is complex. A history of joint injury and participation in high joint loading sports increases the risk of subsequent osteoarthritis changes in affected joints. The impact of osteoarthritis on sports careers depends on multiple factors including the joint involved, the location within that joint, and the physical demands of the chosen sport.
