Injury Incidence in Youth, High School, and NCAA Men's Lacrosse.

We compared injury incidence and mechanisms among youth, high school (HS), and National Collegiate Athletic Association (NCAA) boys' and men's lacrosse athletes for the 2014-2015 to 2016-2017 lacrosse seasons. Multiple injury surveillance systems were used to capture 21 youth boys', 22 HS boys', and 20 NCAA men's lacrosse team-seasons of data during the 2014-2015 to 2016-2017 seasons. Athletic trainers reported game and practice injuries and athlete exposures (AEs). Injuries included those occurring during a game and/or practice and requiring evaluation from an athletic trainer and/or physician. Injury counts, rates per 1000 AEs, and injury rate ratios (IRRs) with 95% confidence intervals (CIs) were calculated. The injury rate in youth was higher than those reported in HS (10.3 vs 5.3 per 1000 AEs; IRR = 2.0; 95% CI: 1.6-2.4) and the NCAA (10.3 vs 4.7 per 1000 AEs; IRR = 2.2; 95% CI: 1.9-2.5). When considering time loss injuries only (restricted participation of ≥24 hours), the injury rate in youth was lower than those reported in HS (2.0 vs 2.9 per 1000 AEs; IRR = 0.7; 95% CI: 0.5-0.95) and the NCAA (2.0 vs 3.3 per 1000 AEs; IRR = 0.6; 95% CI: 0.4-0.8). The concussion rate in youth was higher than those in HS (0.7 vs 0.3 per 1000 AEs; IRR = 2.4, 95% CI: 1.1-5.2) and the NCAA (0.7 vs 0.3 per 1000 AEs; IRR = 2.1, 95% CI: 1.2-3.7). Injuries at the youth, HS, and NCAA levels were most commonly associated with stick contact, inflammatory conditions (including bursitis, tendonitis, and other unspecified inflammation), and noncontact mechanisms, respectively. Although the time loss injury rate was lowest in youth boys' lacrosse, the concussion rate was the highest. Injury prevention approaches should be specific to the mechanisms associated with each level of play (eg, equipment skill development in youth).

Epidemiology of Hand and Wrist Injuries in NCAA Men's Football: 2009-2010 to 2013-2014.

Background:Participation in National Collegiate Athletic Association (NCAA) football is at an all-time high. This population of athletes experiences a substantial injury burden, with many injuries affecting the upper extremities.Purpose/Hypothesis:The purpose of this study was to describe the epidemiology of hand and wrist injuries in college football players from the academic years 2009–2010 to 2013–2014. We hypothesized that variables such as event type (practice vs game), mechanism of injury, and player position would have an effect on the injury incidence.Study Design:Descriptive epidemiological study.Methods:An epidemiological study utilizing the NCAA Injury Surveillance Program was performed to investigate rates and patterns of hand and wrist injuries in participating varsity football teams from 2009–2010 to 2013–2014.Results:A total of 725 hand and wrist injuries were captured in 899,225 athlete-exposures. The observed practice injury rate was 0.51 injuries per 1000 athlete-exposures, compared with a game injury rate of 3.60 (P < .01). Player-on-player contact was the most common injury mechanism reported, with blocking being the most common activity at the time of injury. Offensive linemen were most likely to experience an injury. Of all injuries sustained, 71.4% resulted in no time loss from competition, whereas 9.8% of injuries resulted in longer than 7 days of time loss. A fracture resulted in the greatest time loss from competition (mean ± SD, 8.3 ± 24.0 days; median, 0 days [range, 0-148 days] for injuries sustained in a practice setting) (mean ± SD, 7.7 ± 15.8 days; median, 0 days [range, 0-87 days] for injuries sustained in a game setting).Conclusion:Hand and wrist injuries were found to be significantly more common in games when compared with practices. This study provides valuable prognostic data regarding expected time loss on a per-injury pattern basis. Further investigation on specific injury subtypes and expected time loss as a result of these injures would provide trainers, players, and coaches with useful information on an expected postinjury recovery and rehabilitation timeline.

Changes in injury incidences and causes in Swiss amateur soccer between the years 2004 and 2015.

Injury prevention in amateur soccer has been promoted in recent years, but only a few studies have addressed long-term changes in injury incidence in amateur soccer. However, better knowledge of changes with respect to injury incidences and causes could make an important contribution to improving prevention strategies. The aim of this study was to investigate the long-term development of injury incidence in Swiss amateur soccer with respect to level of play, injury causes and injury characteristics. A representative sample of about 1000 Swiss amateur soccer coaches was interviewed by telephone in 2004, 2008 and 2015. They were asked to recall their last game and to report details on all injuries. For every injury, the coaches were asked to remember injury characteristics and causes. The same procedure was repeated for all games that took place during the previous 4 weeks. Additionally, all training injuries in the previous 4 weeks were recorded in detail. The incidence of game injuries decreased between the years 2004 and 2008 from 15.1 (95% confidence interval [CI] 14.2&ndash;16.0) to 13.3 (95% CI 12.4&ndash;14.2) injuries per 1000 hours, and increased between the years 2008 and 2015 to 16.5 (95% CI 15.5&ndash;17.4) injuries per 1000 hours. Between 2004 and 2015, the rate of contact injuries during games increased by 19.1%. The incidence of foul play injuries in games increased by 25.5% between 2008 and 2015. The rise in total training injury incidence between the years 2004 (2.4, 95% CI 2.2&ndash;2.7) and 2015 (2.9, 95% CI 2.6&ndash;3.1) was caused by a 22.2% higher rate of noncontact injuries. During the same period, game and training injury incidences increased across all amateur soccer leagues without exception, but these changes did not reach statistical significance. In 2015, the incidence of injuries leading to medical attention was higher than in 2004 (game 20.0%, training 37.5%). There is evidence that injury incidence in Swiss amateur soccer has increased in past years. &nbsp.

Epidemiology of boxing injuries in the Olympic Games: Prospective injury surveillance at three consecutive events

The First Decade of Web-Based Sports Injury Surveillance: Descriptive Epidemiology of Injuries in US High School Boys' Soccer (2005-2006 Through 2013-2014) and National Collegiate Athletic Association Men's Soccer (2004-2005 Through 2013-2014).

The advent of Web-based sports injury surveillance via programs such as the High School Reporting Information Online system and the National Collegiate Athletic Association Injury Surveillance Program has aided the acquisition of boys' and men's soccer injury data. To describe the epidemiology of injuries sustained in high school boys' soccer in the 2005-2006 through 2013-2014 academic years and collegiate men's soccer in the 2004-2005 through 2013-2014 academic years using Web-based sports injury surveillance. Descriptive epidemiology study. Online injury surveillance from soccer teams of high school boys (annual average = 100) and collegiate men (annual average = 41). Boys' or men's soccer players who participated in practices and competitions during the 2005-2006 through 2013-2014 academic years in high school and the 2004-2005 through 2013-2014 academic years in college, respectively. Athletic trainers collected time-loss (≥24 hours) injury and exposure data. Injury rates per 1000 athlete-exposures (AEs), injury rate ratios (IRRs) with 95% confidence intervals (CIs), and injury proportions by body site and diagnosis were calculated. High School Reporting Information Online documented 2912 time-loss injuries during 1 592 238 AEs; the National Collegiate Athletic Association Injury Surveillance Program documented 4765 time-loss injuries during 686 918 AEs. The injury rate was higher in college than in high school (6.94 versus 1.83/1000 AEs; IRR = 3.79; 95% CI = 3.62, 3.97). Injury rates increased with smaller school size for high schools and were higher in Division I than in Divisions II and III. The injury rate was higher during competitions than during practices in both high school (IRR = 3.55; 95% CI = 3.30, 3.83) and college (IRR = 3.45; 95% CI = 3.26, 3.65). Most injuries were to the lower extremity. However, concussion was a common injury, particularly in collegiate goalkeepers and at all positions for high school players. Concussions accounted for more than one-fifth of injuries in high school games. Injury-prevention interventions should be tailored to reflect variations in the incidence and type of injury by level of competition, event type, and position.

Costs resulting from nonprofessional soccer injuries in Switzerland: A detailed analysis

BackgroundSoccer injuries constitute an important public health problem and cause a high economic burden. Nevertheless, comprehensive data regarding injury costs in nonprofessional soccer are missing. The aim of this study was to determine which groups of nonprofessional soccer athletes, injury types, and injury situations caused high injury costs. MethodsA cross-sectional, retrospective telephone survey was carried out with a random sample of persons who had sustained a soccer injury between July 2013 and June 2014 and who had reported this accident to the Swiss National Accident Insurance Fund (Suva). One year after the corresponding accident, every injury was linked to its costs and to the answers obtained in the interview about injury setting, injury characteristics, and injury causes. Finally, the costs of 702 injuries were analyzed. ResultsThe average cost of an injury in nonprofessional soccer amounted to €4030 (bias-corrected and accelerated 95% confidence interval (BCa 95%CI): 3427–4719). Persons aged 30 years and older experienced 35% of soccer injuries but accounted for 49% of all costs. A total of 58% of all costs were the result of injuries that occurred during amateur games. In particular, game injuries sustained by players in separate leagues for players aged 30+/40+ years led to high average costs of €8190 (BCa 95%CI: 5036–11,645). Knee injuries accounted for 25% of all injuries and were responsible for 53% of all costs. Although contact and foul play did not lead to above-average costs, twisting or turning situations were highly cost relevant, leading to an average sum of €7710 (BCa 95%CI: 5376–10,466) per injury. ConclusionNonprofessional soccer players aged 30 years and older and particularly players in 30+/40+ leagues had above-average injury costs. Furthermore, the prevention of knee injuries, noncontact and nonfoul play injuries, and injuries caused by twisting and turning should be of highest priority in decreasing health care costs.

Effects of the Gaelic Athletic Association 15 on Lower Extremity Injury Incidence and Neuromuscular Functional Outcomes in Collegiate Gaelic Games

Schlingermann, BE, Lodge, CA, Gissane, C, and Rankin, PM. Effects of the Gaelic Athletic Association 15 on lower extremity injury incidence and neuromuscular functional outcomes in collegiate Gaelic games. J Strength Cond Res 32(7): 1993-2001, 2018-The purpose of this observational analytical cohort study was to assess the effectiveness of an injury prevention program (IPP)-Gaelic Athletic Association 15 (GAA15)-on the incidence of injury in collegiate Gaelic games. One hundred and thirty-one Gaelic games players (mean age 20.5 years ± SD 3.0) were used for analysis in this study. Participants completed preseason and postseason testing which involved performance of the Y-Balance Test. The GAA15 was used for the intervention group; coaches were instructed to implement the program before every training session and match throughout the collegiate Gaelic Athletic Association (GAA) season. The control group adopted their normal warm-up procedures for the season. The players' injuries were documented on a weekly basis by allied health care professionals working with the teams using an online database system. Results showed significant improvements in composite Y-Balance scores in favor of the intervention group (adjusted mean difference Right: 1.8 % normalized mean reach distance (%NMRD) [p = 0.007]/Left: 2.3 %NMRD [p = 0.001]). Injury rates in the intervention group (2.62 injuries per 1,000 hours) were reduced by 66% (p = 0.001) in comparison with an age-matched control group (7.62 per 1,000 hour). Training injuries, hamstring injuries, noncontact injuries, and severe injuries were also reduced as a result of the implementation of the GAA15 (injury rate ratio: 0.20, 0.59, 0.39, and 0.45, respectively). Implementation of an IPP such as the GAA15 can reduce the risk of injury in Gaelic games and influence players' neuromuscular performance assessed through the Y-Balance Test.

Epidemiology of Injuries in Women's Lacrosse: Implications for Sport-, Level-, and Sex-Specific Injury Prevention Strategies

By the end of 2013, the United States had an estimated 278 000 female lacrosse players, with half of those participating at the youth level. The effects of the sport's rapid growth on injury rates have yet to be determined. The purpose of this clinical review is to synthesize the available published data on injuries that have occurred in the sport of women's lacrosse. Of particular interest was the risk of injury based on the level of play and position. A comprehensive literature search was performed in PubMed, High Wire Press, SPORTDiscus, Google Scholar, and Ovid using the keywords "Lacrosse Injuries," "Epidemiology Lacrosse Injuries," "Lacrosse Injury," "Lacrosse," and "Injury." The electronic search included material published during or after 1950. In addition, all bibliographies of electronically found sources were cross-referenced to identify any additional publications that were not produced in the electronic searches. All articles with data on women's injury rates were categorized by overall injury rates, rates by session (competition vs practice), nature of injury, location, type, severity, and player position. Injury rates increase with age: from youth leagues to high school and finally to the collegiate level. Rates of injury varied from 0.03 to 3.9 injuries/100 athletes. Women's game injury rates are consistently higher than practice injury rates (ranging from 0.2 to 7.1 vs 0.01 to 3.3). Injuries occur most frequently from stick-to-player or player-to-ball contact, rather than player-to-player contact. Women sustain a higher percentage of head and facial injuries relative to male lacrosse players. The most common types of injuries for women are concussions, sprains, contusions, and lacerations. More than half of all injuries are in the mild category resulting in players missing practice and games for 1 to 7 days. Offensive players had the most injuries, followed by defensive players and then midfielders, with goalies having the fewest number of injuries. In women's lacrosse, the rules and equipment used are substantially different than for the men's game. Face and hand injuries are more prevalent for women when compared with men, and ankle injuries are most prevalent in female youth. Medical professionals who treat lacrosse players can benefit from an improved understanding of the types and rates of the injuries they are likely to encounter. Improved awareness of lacrosse-specific injuries can assist these professionals to be more prepared to treat these athletes, which may lead to improved care and outcomes.

It's a Hard-Knock Life: Game Load, Fatigue, and Injury Risk in the National Basketball Association.

National Basketball Association (NBA) athletes experience a high rate of injuries. Injury prevention requires identifying observable and controllable risk factors. To examine the relationship among game load, fatigue, and injuries in NBA athletes. Cross-sectional study. Game statistics and injury reports over 3 NBA seasons (2012-2015). Data represented 627 players (height = 200.7 ± 8.9 cm, mass = 100.6 ± 12.1 kg, NBA experience = 4.8 ± 4.2 years, pre-NBA experience = 3.2 ± 1.9 years), 73 209 games, and 1663 injury events. An injury event was defined as a player missing or leaving a game due to injury. Logistic multilevel regression was used to predict injuries from time-lagged fatigue and game load with between-subjects differences explained by demographic variables. The odds of injury increased by 2.87% ( P < .001) for each 96 minutes played and decreased by 15.96% ( P < .001) for each day of rest. Increases in game load increased injury odds by 8.23% ( P < .001) for every additional 3 rebounds and 9.87% ( P < .001) for every additional 3 field-goal attempts. When fatigue and game load were held constant, injury odds increased by 3.03% ( P = .04) for each year of NBA experience and 10.59% ( P = .02) for a 6-cm decrease in height. I observed variability in the intercepts ( P < .001) and the slopes for minutes, rest, field-goal attempts, and rebounds (all P < .001). Injuries were associated with greater fatigue and game load, more years of NBA experience, and being shorter than average. Both baseline injury risk and the magnitude of the load-injury and fatigue-injury associations varied across individuals. Researchers should explore the nature of these relationships.

Injuries in Japanese Junior Soccer Players During Games and Practices.

Soccer is the most popular junior sport in the world. In junior sports, injury analysis and injury-prevention measures for players, especially those under 12 years of age, are urgently needed. To prospectively study the incidence, sites, types, and mechanisms of injuries in elementary school-aged junior soccer players during games and practices. Descriptive epidemiology study. Elementary school-aged junior soccer teams in Nagoya, Japan. Eighty-nine players in 5 community-based club teams of junior soccer (U-12, age range = 11-12 years; U-11, age range = 10-11 years; U-10, age ≤10 years). Data on all game and practice injuries for the 2013-2014 season were collected using an injury report form. Injury rates were calculated according to injury site, type, and mechanism. The overall injury rate was 2.59/1000 athlete-hours (AHs). The game injury rate (GIR; 6.43/1000 AHs) was higher than the practice injury rate (PIR; 1.49/1000 AHs; P < .05). The most common anatomical areas of injury during games and practices were the lower limbs (62.5% and 4.02/1000 AHs versus 38.5% and 0.57/1000 AHs, respectively). Contusions (27.6%, n = 8) were the most frequent type of overall injuries. Most game injuries resulted from body contact (43.8%, 2.81/1000 AHs), whereas most practice injuries resulted from other types of contact (53.8%, 0.83/1000 AHs). The GIRs were higher than the PIRs in Japanese junior soccer players. A lower overall PIR suggested that players in the U-12 age group practiced under appropriate conditions. However, the higher GIR in this age category needs to be decreased.

Examining Play Counts and Measurements of Injury Incidence in Youth Football.

Whereas researchers have provided estimates for the number of head impacts sustained within a youth football season, less is known about the number of plays across which such impact exposure occurs. To estimate the number of plays in which youth football players participated during the 2013 season and to estimate injury incidence through play-based injury rates. Descriptive epidemiology study. Youth football. Youth football players (N = 2098; age range, 5-15 years) from 105 teams in 12 recreational leagues across 6 states. We calculated the average number of athlete-plays per season and per game using independent-samples t tests to compare age groups (5-10 years old versus 11-15 years old) and squad sizes (<20 versus ≥20 players); game injury rates per 1000 athlete-exposures (AEs) and per 10 000 athlete-plays; and injury rate ratios (IRRs) with 95% confidence intervals (CIs) to compare age groups. On average, youth football players participated in 333.9 ± 178.5 plays per season and 43.9 ± 24.0 plays per game. Age groups (5- to 10-year-olds versus 11- to 15-year-olds) did not differ in the average number of plays per season (335.8 versus 332.3, respectively; t2086.4 = 0.45, P = .65) or per game (44.1 versus 43.7, respectively; t2092.3 = 0.38, P = .71). However, players from smaller teams participated in more plays per season (373.7 versus 308.0; t1611.4 = 8.15, P < .001) and per game (47.7 versus 41.4; t1523.5 = 5.67, P < .001). Older players had a greater game injury rate than younger players when injury rates were calculated per 1000 AEs (23.03 versus 17.86/1000 AEs; IRR = 1.29; 95% CI = 1.04, 1.60) or per 10 000 athlete-plays (5.30 versus 4.18/10 000 athlete-plays; IRR = 1.27; 95% CI = 1.02, 1.57). A larger squad size was associated with a lower average number of plays per season and per game. Increasing youth football squad sizes may help reduce head-impact exposure for individual players. The AE-based injury rates yielded effect estimates similar to those of play-based injury rates.

Acute injuries in Finnish junior floorball league players

ObjectivesTo investigate the incidence and characteristics of acute time-loss injuries in Finnish junior floorball league players. DesignProspective cohort study with 3-year follow-up. MethodsOne hundred and eighty-six female and male players (mean age 16.6±1.4) took part in the follow-up study (2011–2014). The training hours and games were recorded on a team diary. Floorball related acute injuries were registered and verified by a research physician. The injury incidence was expressed as the number of injuries per 1000h of exposure. Incidence rate was calculated separately for games and practices, and for males and females. ResultsOne hundred and forty-four acute time-loss injuries occurred. Injury incidence was 26.87 (95% CI 20.10–33.63) in junior league games, and 1.25 (95% CI 0.99–1.52) in team practices. Female players had significantly higher game injury rate (IRR 1.88, 1.12–3.19) and joint/ligament injury rate (IRR 1.70, 1.07–2.73) compared to males. Eighty-one percent of the injuries affected the lower limbs. The ankle (37%), knee (18%), and thigh (14%) were the most commonly injured body sites. More than half of injuries involved joint or ligaments (54%). Twenty-six percent of the injuries were severe causing more than 28days absence from sports. Eight anterior cruciate ligament ruptures of the knee occurred among seven female players. ConclusionThe study revealed that risk of ankle and knee ligament injuries is high in adolescent floorball, specifically among female players.

SPORTS INJURIES AMONG AMATEUR ATHLETES AT A BRAZILIAN UNIVERSITY.

ABSTRACTObjective: To obtain information on the incidence and nature of sports injuries at a Brazilian university.Method: Data from 396 student amateur athletes (61% male) playing 15 different sports during the 2013 season were retrospectively evaluated. Subjects completed the National Collegiate Athletic Association Injury Surveillance System questionnaire at the conclusion of the 2013 sports season. Injuries that resulted in at least one day of time lost were included. Exposure was defined as one student amateur athlete participating in one practice or game and is expressed as an athlete-exposure (A-E).Results: Injury rates were significantly greater in games (13.13 injuries per 1000 A-Es, 95% CI = 10.3-15) than in practices (4.47 injuries per 1000 A-Es, 95% CI = 3.9-5.1). The mechanisms that accounted for the most injuries in games and practices were player contact (52.9%) and non-contact (54.5%), respectively. Ankle ligament sprains were the most common injury (18.2% of all reported injuries). A relatively high incidence of anterior cruciate ligament injury was also observed (0.16 injuries per 1000 A-Es).Conclusion: Brazilian student amateur athletes are at great risk of sustaining non-contact injuries such as ankle sprains and anterior cruciate ligament injuries. Level III of Evidence, Study of non consecutive patients; without consistently applied reference ''gold'' standard.

The Influence of Playing Experience and Position on Injury Risk in NCAA Division I College Football Players.

American football is widely played by college student-athletes throughout the United States; however, the associated injury risk is greater than in other team sports. Numerous factors likely contribute to this risk, yet research identifying these risk factors is limited. The present study sought to explore the relationship between playing experience and position on injury risk in NCAA Division I college football players. Seventy-six male college student-athletes in the football program of an American NCAA Division I university participated. Injuries were recorded over 2 consecutive seasons. Players were characterized based on college year (freshman, sophomore, junior, or senior) and playing position. The effect of playing experience and position on injury incidence rates was analyzed using a generalized linear mixed-effects model, with a Poisson distribution, log-linear link function, and offset for hours of training exposure or number of in-game plays (for training and game injuries, respectively). The overall rates of non-time-loss and time-loss game-related injuries were 2.1 (90% CI: 1.8-2.5) and 0.6 (90% CI: 0.4-0.8) per 1000 plays, respectively. The overall rates of non-time-loss and time-loss training-related injuries were 26.0 (90% CI: 22.6-29.9) and 7.1 (90% CI: 5.9-8.5) per 1000 h, respectively. During training, seniors and running backs displayed the greatest risk. During games, sophomores, juniors, and wide receivers were at greatest risk. Being aware of the elevated injury risk experienced by certain player groups may help coaches make considered decisions related to training design and player selection.

Injuries during the international floorball tournaments from 2012 to 2015

BackgroundFloorball is a running indoor team sport that has growing popularity worldwide. Some prospective studies have investigated injuries in national floorball leagues, but such studies at the international level are...
