Abstract
OBJECTIVE To describe the epidemiology of body checking injuries in the National Collegiate Athletic Association (NCAA) Men's Ice Hockey. DESIGN Secondary data analysis of historical cohort data. SETTING A convenience sample of injuries in NCAA Men's Ice Hockey during the 2009/10 to 2019/20 academic years. PATIENTS OR PARTICIPANTS NCAA student-athletes. INDEPENDENT VARIABLES Event type, season, time loss, body part, diagnosis, player position, and mechanism. MAIN OUTCOME MEASURES This study examined injuries that occurred during practice or competition, regardless of time loss, reported to the NCAA Injury Surveillance Program. Injury counts, rates, and proportions were used. The injury rate and proportion ratios with 95% confidence intervals were also constructed. Three independent logistic regression models were constructed to examine differential odds of time loss (≥1 day; TL) injury and the 2 most common injuries, between body checking injuries and all other injuries. RESULTS Overall, 1290 body checking injuries (rate = 1.59/1000 athlete-exposures) were reported during the study period. Most were attributed to the upper extremity (42%) or head/neck (27%). The competition injury rate generally decreased after 2012/13. After adjusting for covariates, odds of (1) a TL injury was lower and (2) an acromioclavicular sprain was higher among body checking injuries as compared with injuries attributed to all other activities. Odds of concussion was not associated with body checking injuries. CONCLUSIONS Body checking injuries were frequently attributed to the head/neck and upper extremities, and the rate of these injuries during competition appeared to be decreasing. Still, improvements in helmet and shoulder pad technology may further improve health and safety.

Abstract
BACKGROUND Ice hockey players are at high risk for hip and groin injury. Several risk factors have been identified or proposed, including lower hip rotation range of motion (ROM), lower hip adductor strength, lower ratio of hip adductor to abductor strength, and lower pelvic tilt angle. It is not known how these risk factors change acutely with ice hockey participation. HYPOTHESIS Acute exposure to ice hockey will result in a reduction in ROM, strength, and pelvic tilt angle in competitive male players. STUDY DESIGN Controlled cohort study. LEVEL OF EVIDENCE Level 3. METHODS Risk factors for hip and groin injury, including isometric hip adductor strength at 0° of flexion, the ratio of hip adductor to abductor strength, total hip rotation passive ROM in supine, and the resting pelvic tilt angle, were assessed immediately before, immediately after, and 24 hours after an ice hockey exposure in 42 competitive male ice hockey players. Rating of perceived exertion (RPE) was collected to identify the intensity of the exposure. RESULTS There was a significant decrease in total hip rotation ROM (-7.32°, P < 0.01 (-3.91, -10.70)) and hip adductor strength (-4.41 kg, P < 0.01 (-2.81, -6.00) immediately after the exposure, and a significant decrease in total hip rotation ROM (-18.54°, P < 0.01 (-14.35, -22.73)), hip adductor strength (-6.56 kg, P < 0.01 (-4.58, -8.61)), and the ratio of hip adductor to abductor strength (-0.12, P < 0.01 (-0.21, -0.45)) 24 hours after. There was no significant change in pelvic tilt found in this study immediately after or 24 hours after. There was a moderate relationship between changes in hip adductor strength and changes in the ratio of hip adductor to abductor strength (r = 0.433, P < 0.01). RPE was not significantly correlated to any of the changes observed. CONCLUSION Risk factors for hip and groin injury in ice hockey players are modifiable after a single ice hockey exposure. CLINICAL RELEVANCE The identified fluctuation of injury risk factors for hip and groin injury in ice hockey players has implications for injury risk profiling, rehabilitation, and return-to-competition decision-making.

Abstract
BACKGROUND Injury characteristics of high school track and field throwing athletes in the United States are not well studied. Understanding epidemiology of injuries is important to identify treatment and prevention strategies. OBJECTIVE To describe injury rates and patterns in U.S. high school track and field throwing events from a longitudinal national sports injury surveillance system. DESIGN Descriptive epidemiology study. SETTING Data were provided by the National High School Sports Related Injury Surveillance System, High School RIO (Reporting Information Online). METHODS Athletic trainers reported injury and exposure data through the High School RIO website on a weekly basis. An athlete exposure (AE) was defined as one athlete participating in one school-sanctioned practice or competition. Throwing events of discus, shot put, and javelin were analyzed in this study. MAIN OUTCOME MEASURES Injury rate, rate ratios (RR), injury proportion ratios (IPR). PARTICIPANTS U.S. high school athletes. RESULTS A total of 267 track and field throwing injuries occurred during 5,486,279 AEs. Overall, the rate of injuries in competition was higher than in practice (RR 1.35, 95% confidence interval [CI] 1.01-1.80). In practice, the rate of injuries was higher for girls than boys (RR 1.53, 95% CI 1.12-2.08). The most frequently injured body part was the shoulder (21.7%), followed by the ankle (16.5%) and knee (12.0%). The most common types of injury were muscle strains (26.14%) and ligament sprains (25%). Recurrent injuries accounted for a higher proportion of chronic injuries compared to new injuries (IPR 1.85, 95% CI 1.16-2.97). CONCLUSION This study described injury characteristics of high school track and field throwing athletes from 2008 to 2019. Based on our results, injury prevention may be particularly important for female throwers with prior injury.

Abstract
CONTEXT Contusion and soft tissue injuries are common in sports. Photobiomodultion, light and laser therapy, is an effective aid to increase healing rates and improve function after various injury mechanisms. However, it is unclear how well photobiomodulation improves function after a contusion soft tissue injury. This study aimed to determine the effects of a pulsed red and blue photobiomodulation light patch on muscle function following a human thigh contusion injury. DESIGN Single-blinded randomized control trial design. METHODS We enrolled 46 healthy participants. Participants completed 5 visits on consecutive days. On the first visit, participants completed a baseline isokinetic quadriceps strength testing protocol at 60°/s and 180°/s. On the second visit, participants were struck in the rectus femoris of the anterior thigh with a tennis ball from a serving machine. Immediately following, participants were treated for 30 minutes with an active or placebo photobiomodulation patch (CareWear light patch system, CareWear Corp). Following the treatment, participants completed the same isokinetic quadriceps strength testing protocol. Participants completed the treatment and isokinetic quadriceps strength test during the following daily visits. We normalized the data by calculating the percent change from baseline. We used a mixed model analysis of covariance, with sex as a covariate, to determine the difference between treatment groups throughout the acute recovery process. RESULTS We found the active photobiomodulation treatment significantly increased over the placebo group, quadriceps peak torque during the 180°/s test (P = .030), and average power during both the 60°/s (P = .041) and 180°/s (P ≤ .001) assessments. The mean peak torque and average power of 180°/s, at day 4, exceeded the baseline levels by 8.9% and 16.8%, respectively. CONCLUSIONS The red and blue photobiomodulation light patch improved muscle strength and power during the acute healing phase of a human thigh contusion injury model.

Estimating the Relationship Between the Symptom-Free Waiting Period and Injury Rates After Return-to-Play from Concussion: A Simulation Analysis Using CARE Consortium Data. Sports Med 2023; 53:2513-2528. [PMID: 37610654 DOI: 10.1007/s40279-023-01901-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/25/2023] [Indexed: 08/24/2023]
Abstract
BACKGROUND A key component of return-to-play (RTP) from sport-related concussion is the symptom-free waiting period (SFWP), i.e., the period during which athletes must remain symptom-free before permitting RTP. Yet, the exact relationship between SFWP and post-RTP injury rates is unclear. OBJECTIVE We design computational simulations to estimate the relationship between the SFWP and rates of repeat concussion and non-concussion time-loss injury up to 30 days post-RTP for male and female collegiate athletes across 13 sports. METHODS We leverage N = 735 female and N = 1,094 male post-injury trajectories from the National Collegiate Athletic Association-Department of Defense Concussion Assessment, Research, and Education Consortium. RESULTS With a 6-day SFWP, the mean [95% CI] rate of repeat concussion per 1,000 simulations was greatest in ice hockey for females (20.31, [20.16, 20.46]) and American football for males (24.16, [24.05, 24.28]). Non-concussion time-loss injury rates were greatest in field hockey for females (153.66, [152.59, 154.74]) and wrestling for males (247.34, [246.20, 248.48]). Increasing to a 13-day SFWP, ice hockey for females (18.88, [18.79, 18.98]) and American football for males (23.16, [23.09, 24.22]) exhibit the greatest decrease in repeat concussion rates across all sports within their respective sexes. Field hockey for females (143.24, [142.53, 143.94]) and wrestling for males (237.73, [236.67, 237.90]) exhibit the greatest decrease in non-concussion time-loss injury rates. Males receive marginally smaller reductions in injury rates for increased SFWP compared to females (OR = 1.003, p ≤ 0.002). CONCLUSION Longer SFWPs lead to greater reductions in post-RTP injury rates for athletes in higher risk sports. Moreover, SFWPs should be tailored to sport-specific post-RTP injury risks.

Abstract
ABSTRACT Femoroacetabular impingement (FAI) in ice hockey is a concern for many athletes. The biomechanics of skating and the injury mechanism, prevalence, identification, and treatment protocols currently available for FAI in ice hockey athletes are important for all coaches and practitioners to understand. This article discusses the underlying anatomical issues and biomechanical considerations surrounding FAI. Furthermore, this article describes the interventions that can be used when encountering FAI and well-established protocols to aid in the return to play. Finally, prevention strategies that can aid in injury prevention are discussed.

Abstract
Inline skater hockey is a sport originating from ice hockey, which is practised in Germany by about 6000 athletes. There are some differences to ice hockey, which lead to a special risk profile of the athletes.All 315 active players of the First German Inline Skater Hockey League in the years 2018 and 2019 were contacted to participate in an online survey. The subjects of the study completed an anonymised 83-item multiple-choice questionnaire about injuries, training frequency, training content, and sports equipment. 178 athletes responded and 116 questionnaires could be analysed (100 men, 8 women, 8 without information/16 goalies, 55 forwards, 44 defenders).The overall injury incidence was 36.98 per 1000 hours. Minor injuries (wounds, bruises, and blunt muscle injuries) most frequently comprised leg injuries (9.4/1000 hours) and arm injuries (7.2/1000 hours). Relevant injuries (fractures, dislocations, and ligamentous injuries) were most common to the foot (2.4/1000 hours) (n=147) and to the head (1.9/1000 hours) (n=140) and knee (1.7/1000 hours) (n=126). Of 76 fractures, 48 (63.2%) resulted from direct or indirect body contact. Goalkeepers suffered more knee injuries compared with field players, while field players sustained more shoulder injuries. Head injuries (fractures, dental injuries, traumatic brain injuries) were significantly more frequent in players without face protection (3.0/1000h vs. 1.8/1000h). Players who did not perform additional fitness training had significantly more relevant injuries. In this group, knee injuries occurred more frequently as well (4.2/1000h vs. 1.3/1000h). The duration of stretching exercises showed a negative correlation with overall injury incidence (0 minutes: 53.5/1000 hours, 1-4 minutes: 55.8/1000 hours, 5-9 minutes: 23.5/1000 hours, ≥10 minutes: 21.5/1000 hours, p<0.05).In particular, mild injuries occurred with a highly significant reduction in frequency if the subjects performed stretching exercises. Inline skater hockey in the First German League is characterised by a high risk of injury, which can be compared with professional ice hockey. Serious injuries are mainly caused by physical contact. Relevant injuries are most common to the head and lower extremity. The implementation of fitness training had a positive influence on the frequency of injuries. In the context of further professionalisation of this sport, these findings can contribute to the prevention of injuries in inline skater hockey.

Abstract
Background The sport of ice hockey has reached worldwide popularity, and it continues to grow. With this growth, however, there has also been an increase in the number of injuries related to the high-speed physical nature of the sport. Upper extremity related traumas and maladies are amongst the most commonly experienced injuries in this population of athletes. The objective of this narrative review is to appraise the current literary landscape as to the epidemiology, treatment, and return to play experienced with the most common upper extremity orthopedic injuries related to ice hockey play. Methods PubMed, Google Scholar, and OVID were searched individually using the filtered terms "shoulder", "injury", and "ice hockey". Articles that were published after 2000 were analyzed. Notably, the concepts of athlete sex, compete level, and post injury productivity were explored in detail. Results It is evident in the literature that upper extremity injury rates increased as level of play increased, were more common in males, and occurred more often during in-game situations. Acromioclavicular joint separations, shoulder instability, and clavicle fractures were amongst the most commonly cited ice hockey upper extremity injury presentations; acromioclavicular joint injuries were considered the most common upper extremity injury in ice hockey players. Return to play depends on injury type and severity. Overall, performance decreased upon initial return from injury. Conclusion Ultimately, further research needs to be conducted on shoulder related ice hockey injuries, their prevention, and the accurate management of specific presentations in order to ensure efficient and safe return to play.

Abstract
PURPOSE OF REVIEW The objectives of this review are to explore the recent literature evaluating sports-related shoulder injuries among female athletes. RECENT FINDINGS Recent literature has highlighted sex-related differences in injury trends and patterns among athletes. Increased participation of women in both recreational and professional sports has resulted in increased exposure to injury. While men experience greater rates of shoulder injury overall, women tend to experience more overuse-related injuries. Evidence also suggests women are more susceptible to shoulder laxity and rotator cuff tears. In comparison to their male counterparts, women note poorer function, increased pain, and decreased activity level following shoulder injuries. Women may also be more likely to experience worse outcomes following surgical intervention. Sex-related differences in injury patterns and outcomes results from a combination of molecular and environmental influences, including hormone pathways, shoulder morphology, and differing rates of participation in, and athletic regulations among, certain sports. Sex-related differences occur in how athletes sustain, experience, and recover from sports-related injuries. A comprehensive understanding of sex-related injuries enhances clinical decision making, treatment, and recovery. Further research is needed to clarify sex as an independent variable when evaluating sports-related shoulder injuries.

Abstract
BACKGROUND The prevalence of unreported concussions is high, and undiagnosed concussions can lead to worse postconcussion outcomes. It is not clear how those with a history of undiagnosed concussion perform on subsequent standard concussion baseline assessments. PURPOSE To determine if previous concussion diagnosis status was associated with outcomes on the standard baseline concussion assessment battery. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Concussion Assessment, Research, and Education (CARE) Consortium participants (N = 29,934) self-reported concussion history with diagnosis status and completed standard baseline concussion assessments, including assessments for symptoms, mental status, balance, and neurocognition. Multiple linear regression models were used to estimate mean differences and 95% CIs among concussion history groups (no concussion history [n = 23,037; 77.0%], all previous concussions diagnosed [n = 5315; 17.8%], ≥1 previous concussions undiagnosed [n = 1582; 5.3%]) at baseline for all outcomes except symptom severity and Brief Symptom Inventory-18 (BSI-18) score, in which negative binomial models were used to calculate incidence rate ratios (IRRs). All models were adjusted for sex, race, ethnicity, sport contact level, and concussion count. Mean differences with 95% CIs excluding 0.00 and at least a small effect size (≥0.20), and those IRRs with 95% CIs excluding 1.00 and at least a small association (IRR, ≥1.10) were considered significant. RESULTS The ≥1 previous concussions undiagnosed group reported significantly greater symptom severity scores (IRR, ≥1.38) and BSI-18 (IRR, ≥1.31) scores relative to the no concussion history and all previous concussions diagnosed groups. The ≥1 previous concussions undiagnosed group performed significantly worse on 6 neurocognitive assessments while performing better on only 2 compared with the no concussion history and all previous concussions diagnosed groups. There were no between-group differences on mental status or balance assessments. CONCLUSION An undiagnosed concussion history was associated with worse clinical indicators at future baseline assessments. Individuals reporting ≥1 previous undiagnosed concussions exhibited worse baseline clinical indicators. This may suggest that concussion-related harm may be exacerbated when injuries are not diagnosed.

Abstract
Background Youth around the globe place their shoulders at risk for injury when participating in sports. Shoulder injuries may vary in severity, produce the potential for time-loss from sport, and result in functional disability. We sought to explore sport-related shoulder injuries in youth by identifying injury rates, risk factors, injury mechanisms, and injury prevention strategies. Methods All relevant full-text articles were identified by searching MEDLINE, EMBASE, CINAHL, Sport Discus, and the Cochrane Controlled Trials Registry. No date restrictions were used. All full-text studies reporting original research describing sport-related shoulder injury among female and/or male youth from 5 to 18 years old were included. Results Of 3,889 studies screened, 97 described shoulder injury in youth sports. Shoulder injuries were identified in 24 unique sports. The median seasonal prevalence of shoulder injury was 10.9% (range 1.2-28.2%). The most common injury mechanisms identified were contacted with another player, contact with the playing environment, and falling to the ground. Risk factors for shoulder injury identified were side-to-side strength imbalances, weak external rotator muscles, and scapular dyskinesia. One study evaluated a successful training strategy to prevent shoulder injuries, but two other interventions demonstrated no effect. Conclusions Sport-related shoulder injuries are prevalent among youth athletes. Injury risk factors identified included modifiable intrinsic factors such as strength, range of motion, and training load. The most common injury mechanism was direct contact with either another person or an object in the playing environment. Innovative shoulder-specific strategies are needed to reduce shoulder injuries in this population. Trial Registration: PROSPERO ID: CRD42020189142.

Abstract
OBJECTIVE Young players experience pressure to focus on ice hockey at the exclusion of other sports in order to improve chances of success. Early specialization in other sports has been associated with increased injury without the benefit of improved success. The objective of the current study was to investigate whether earlier specialization results in increased injury without higher rates of career success. This study also aimed to compare rates of injury in athletes at various levels of competition. METHODS An original survey was issued to men's ice hockey players at the juniorA, collegiate, and professional levels. The survey consisted of 34 questions on various demographic, specialization, and injury variables. All participants were >18 years of age. RESULTS The survey was completed by 101 athletes. The mean age at specialization was 13 (±4) overall and 14 (±3), 13 (±4), and 11(±4) for professional, collegiate, and junior players, respectively. There was no difference in age at specialization between each group and professional players did not specialize earlier than the remainder of the cohort as a whole (p > 0.05). There was no significant correlation between age at specialization and total injuries (p > 0.05). There was no difference in concussions causing missed play time between groups (p > 0.05) but professional players had more overall concussions and underwent more surgeries due to hockey-related injuries (p = 0.01). CONCLUSIONS Specializing exclusively in ice hockey earlier in life was not associated with playing professionally. Both collegiate and professional players do not tend to specialize prior to age 12. Age at specialization was not associated with overall number of injuries. Professional players with longer careers appear to sustain more concussions and undergo more surgery.

Abstract
Concussions are common among flat-track roller derby players, a unique and under-studied sport, but little has been done to assess how common they are or what players can do to manage injury risk. The purpose of this study is to provide an epidemiological investigation of concussion incidence and experience in a large international sampling of roller derby players. Six hundred sixty-five roller derby players from 25 countries responded to a comprehensive online survey about injury and sport participation. Participants also responded to a battery of psychometric assessment tools targeting risk-factors for poor injury recovery (negative bias, social support, mental toughness) and players' thoughts and feelings in response to injury. Per 1,000 athletes, 790.98 concussions were reported. Current players reported an average of 2.2 concussions, while former players reported 3.1 concussions. However, groups were matched when these figures were corrected for differences in years of play (approximately one concussion every 2 years). Other frequent injuries included fractures in extremities and upper limbs, torn knee ligaments, and sprained ankles. We found no evidence that players' position, full-contact scrimmages, or flooring impacted number of concussions. However, neurological history and uncorrected vision were more influential predictors of an individual's number of concussions during roller derby than years of participation or age, though all four contributed significantly. These findings should assist athletes in making informed decisions about participation in roller derby, though more work is needed to understand the nature of risk.

Abstract
Background: Track and field (T&F) athletes compete in a variety of events that require different skills and training characteristics. Descriptive epidemiology studies often fail to describe event-specific injury patterns. Purpose: To describe the epidemiology of injuries in National Collegiate Athletic Association (NCAA) T&F by sex, setting (practice vs competition), and time of season (indoor vs outdoor) and to compare injury patterns by events within the sport. Study Design: Descriptive epidemiology study. Methods: Data were obtained from the NCAA Injury Surveillance Program for all indoor and outdoor T&F injuries during the academic years 2009-2010 to 2013-2014. Injury rates, injury rate ratios, and injury proportion ratios (IPRs) were reported and compared by sex, injury setting, season, and event. Analysis included time-loss as well as no-time loss injuries. Results: Over the 5 seasons, the overall injury rate was 3.99 injuries per 1000 athletic-exposures (95% CI, 3.79-4.20). After controlling for injury diagnoses, women’s T&F athletes experienced an 18% higher risk of injury (95% CI, 7% to 31%) and missed 41% more time after an injury (95% CI, 4% to 93%) when compared with men. Among all athletes, the injury risk during competition was 71% higher (95% CI, 50% to 95%) compared with practice and required 59% more time loss (95% CI, 7% to 135%). Distance running accounted for a significantly higher proportion of overuse injuries (IPR, 1.70; 95% CI, 1.40-2.05; P < .05) and required 168% more time loss (95% CI, 78% to 304%) than other events. The hip and thigh were the body regions most commonly injured; injury type, however, varied by T&F event. Sprinting accounted for the greatest proportion of hip and thigh injuries, distance running had the greatest proportion of lower leg injuries, and throwing reported the greatest proportion of spine and upper extremity injuries. Conclusion: Injury risk in NCAA T&F varied by sex, season, and setting. Higher injury rates were found in women versus men, indoor versus outdoor seasons, and competitions versus practices. The hip and thigh were the body regions most commonly injured; however, injury types varied by event. These findings may provide insight to programs aiming to reduce the risk of injury and associated time loss in collegiate T&F.

Abstract
BACKGROUND Although lower back injuries (LBIs) are common among National Collegiate Athletic Association (NCAA) female volleyball athletes, their incidence and etiology has not been well-defined. PURPOSE To describe the epidemiology of LBIs in collegiate female volleyball athletes over a 5-year period from the academic years 2009 to 2010 and 2013 to 2014. STUDY DESIGN Descriptive epidemiology study. METHODS The incidence and characteristics of spine injuries were identified utilizing the NCAA Injury Surveillance Program database. Rates of injury were calculated as the number of injuries by the total number of athlete-exposures (AEs). AEs were defined as any student participation in any single NCAA-sanctioned practice or competition. The injury rate was computed as the number of injuries per the total number of AEs and reported as a ration of injuries per 10,000 exposures. The ratio was then reported as overall number as well as stratified for event, time of season, and athletic NCAA division. Incidence rate ratios were then calculated to compare rates between event type. Results with 95% CIs that did not include 1.0 were considered statistically significant. RESULTS An estimated 3384 LBIs occurred in NCAA female volleyball players during this 5-year time frame. These LBIs occurred at a rate of 4.89 injuries per 10,000 AEs. LBIs were 2.76 times more likely in preseason when compared with regular season. More injuries occurred in practice (85%) when compared with competition (15%). The outside hitter and middle blocker were the most commonly position to sustain an LBI. Almost 70% of injuries were new injuries, and another 29% were recurrent injuries. The most common mechanism of injury was equally split between contact (50.4%) and overuse (45.5%) injuries, whereas the remaining mechanisms of injury were secondary for unknown reasons (4.14%). Most players returned to play within 24 hours (72.3%) followed by 1 to 6 days (16.4%), and finally 7 to 12 days (11.3%). No patient required surgical intervention. CONCLUSION The rate of LBIs was high (4.89/10,000 AEs) and injuries commonly recurred (29.2%). Most injuries were new, with most athletes returning to play with 24 hours.

Abstract
STUDY DESIGN This review article examines the biomechanics that underly hockey-related cervical spine injuries, the preventative measures to curtail them, optimal management strategies for the injured player and return to play criteria. OBJECTIVE Hockey is a sport with one of the highest rates of cervical spine injury, but by understanding the underlying pathophysiology and context in which these injuries can occur, it is possible to reduce their incidence and successfully manage the injured player. METHODS Multiple online databases including PubMed, Google Scholar, Columbia Libraries Catalog, Cochrane Library and Ovid MEDLINE were queried for original articles concerning spinal injuries in ice hockey. All relevant papers were screened and subsequently organized for discussion in our subtopics. RESULTS Cervical fractures in ice hockey most often occur due to an increased axial load, with a check from behind the most common precipitating event. CONCLUSIONS Despite the recognized risk for cervical spine trauma in ice hockey, further research is still needed to optimize protocols for both mitigating injury risk and managing injured players.

Abstract
CONTEXT The National Collegiate Athletic Association (NCAA) has sponsored women's ice hockey championships since 2001, and sponsorship has grown over time. BACKGROUND Routine examinations of injuries sustained by athletes are important for identifying and understanding patterns that can be used to inform sport safety practices. METHODS Exposure and injury data collected in the NCAA Injury Surveillance Program from 2014-2015 through 2018-2019 were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics, and injury rate ratios were used to examine differential injury rates. RESULTS The overall injury rate was 5.89 per 1000 athlete-exposures; preseason injury incidence rose sharply during 2016-2017 through 2018-2019. Head/face injuries (15.2%), knee injuries (13.2%), and shoulder injuries (12.9%) were the most commonly injured body parts, and injuries were most often classified as contusions (18.9%), strains (18.7%), and sprains (15.5%). Concussion (11.9%) was the most commonly reported specific injury, and concussion rates notably increased during 2017-2018 through 2018-2019. SUMMARY Study findings were generally consistent with the existing epidemiological evidence. Injury incidence in preseason and the etiology of strains warrant further attention in this population.

Abstract
CONTEXT The National Collegiate Athletic Association has supported men's ice hockey, a distinct sport that mandates high-velocity gamesmanship, since 1974. BACKGROUND Injury surveillance systems are designed to identify evolving injury trends and their temporal qualities. Continual monitoring of collegiate men's ice hockey athletes remains essential. METHODS Exposure and injury data collected in the National Collegiate Athletic Association Injury Surveillance Program from 2014-2015 through 2018-2019 were analyzed. Injury counts, rates, and proportions were used to describe injury characteristics, and injury rate ratios (IRR) were used to examine differential injury rates. RESULTS The overall injury rate was 7.65 per 1000 athlete-exposures. Injuries from competition occurred at a rate nearly 7 times that from practice injuries (IRR = 6.54, 95% CI = 6.08, 7.04). The most common specific injury diagnoses were concussions (9.6%), acromioclavicular sprains (7.3%), and medial collateral ligament tears (3.7%). SUMMARY Injury rates by event type and season segment were higher than previously reported. Contusions accounted for nearly a quarter of all injuries, and acromioclavicular sprain rates increased notably across the study period.

Abstract
Appropriate performance tests are critical for documenting training, fatigue and injury-related changes. Functional performance testing can provide quantitative information on specialized sport movements. The single-leg, medial countermovement jump is an objective measure of frontal plane force, velocity and power, and is particularly applicable for ice hockey players given that ice skating involves applying lateral forces. This study assessed the short-term reliability (10 days) of the single-leg, medial countermovement jump performed by ten competitive male youth ice hockey players. Each participant performed three right and three left maximal single-leg, medial countermovement jumps from force plates. Measured variables included lateral and vertical takeoff velocity, lateral and vertical maximal force, maximal force above bodyweight, lateral and vertical peak concentric power, average concentric power, and average concentric power during the last 100 ms of push-off. Relative reliability was quantified by intraclass correlations. Absolute reliability and the smallest real difference were also calculated. The single-leg, medial countermovement jump had moderate-to-excellent test-retest reliability (ICC: 0.50-0.98) for all twelve variables of interest. These results suggest that the single-leg, medial countermovement jump is a reliable test for assessing frontal plane force, velocity and power in ice hockey players, and is a valid functional performance test for this population given the similarity to ice skating.

Abstract
BACKGROUND Concussion is a growing public health concern and generating concussion prevention programs depends on identifying high-risk sports and characteristics. Identifying the roles of sport, sex, and participation level (e.g., high school versus collegiate athletics) in concussion risk would facilitate more informed decision-making regarding sports participation and generate better targeted prevention strategies. OBJECTIVES The current study's objectives were to: (1) determine the magnitude and hierarchy of sports-related concussion (SRC) risk across an array of events and (2) evaluate the modifying roles of sex, participation level, and session type on SRC rates. METHODS A literature search was conducted on PubMed, searching concussion studies published between 2001 and December 2019. Inclusion criteria for studies required: (1) concussion occurred during sport, (2) that the SRC was clinically diagnosed, and (3) athlete exposures and concussions could be extracted or estimated. A study was excluded if it: (1) was not an original research article, (2) was not written in English language, (3) was an animal study, (4) did not have enough data to calculate SRC rates, (5) included professional or youth sample, and/or (6) contained data collected prior to 2001. The meta-analysis and meta-regression analyses were fit using a random effects model. RESULTS Search results returned 2695 unique research articles, with 83 studies included in analyses. Sport, sex, participation level, and session type all significantly influenced SRC rates. Overall, rugby had the highest concussion rate and was classified as the highest risk sport (28.25 concussions per 10,000 athlete exposures). Overall, females had a higher concussion rate than males. Only lacrosse demonstrated a higher concussion rate for males compared to females. Collegiate athletes had higher concussion rates than high school athletes. Games were associated with 2.01 more concussions per 10,000 AEs than practices. CONCLUSIONS This meta-analysis demonstrated rugby has the highest concussion risk, followed by American Football, ice hockey, and wrestling. Concussion risk was influenced by sport, sex, participation, and session. Identifying the factors and environments that influence concussion risk can facilitate risk reduction and prevention strategies.

Detailed description of Division I ice hockey concussions: Findings from the NCAA and Department of Defense CARE Consortium. JOURNAL OF SPORT AND HEALTH SCIENCE 2021; 10:162-171. [PMID: 33453430 PMCID: PMC7987562 DOI: 10.1016/j.jshs.2021.01.004] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 11/25/2020] [Accepted: 12/29/2020] [Indexed: 05/31/2023]
Abstract
OBJECTIVE Since concussion is the most common injury in ice hockey, the objective of the current study was to elucidate risk factors, specific mechanisms, and clinical presentations of concussion in men's and women's ice hockey. METHODS Ice hockey players from 5 institutions participating in the Concussion Assessment, Research, and Education Consortium were eligible for the current study. Participants who sustained a concussion outside of this sport were excluded. There were 332 (250 males, 82 females) athletes who participated in ice hockey, and 47 (36 males, 11 females) who sustained a concussion. RESULTS Previous concussion (odds ratio (OR) = 2.00; 95% confidence interval (95% CI): 1.02‒3.91) was associated with increased incident concussion odds, while wearing a mouthguard was protective against incident concussion (OR = 0.43; 95%CI: 0.22‒0.85). Overall, concussion mechanisms did not significantly differ between sexes. There were specific differences in how concussions presented clinically across male and female ice hockey players, however. Females (9.09%) were less likely than males (41.67%) to have a delayed symptom onset (p = 0.045). Additionally, females took significantly longer to reach asymptomatic (p = 0.015) and return-to-play clearance (p = 0.005). Within the first 2 weeks post-concussion, 86.11% of males reached asymptomatic, while only 45.50% of females reached the same phase of recovery. Most males (91.67%) were cleared for return to play within 3 weeks of their concussion, compared to less than half (45.50%) of females. CONCLUSION The current study proposes possible risk factors, mechanisms, and clinical profiles to be validated in future concussions studies with larger female sample sizes. Understanding specific risk factors, concussion mechanisms, and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies.

Abstract
Sport-related concussions are common in the United States. Concussion rates have increased over time, likely due to improved recognition and awareness. Concussion rates vary across level (high school vs college), sex, and sport. Concussion rates are the highest among men, particularly in football, wrestling, ice hockey, and lacrosse where collisions and contact are inherent to the sports, although girls'/women's soccer rates are high. In gender-comparable sports, women have higher concussion rates. Continued data collection will increase understanding of sport-related concussion and provide areas for targeted prevention in the future.

Abstract
CONTEXT Sport specialization is a popular trend among youth athletes that has been associated with an increased risk for developing lower extremity overuse injuries. Early ice hockey specialization may contribute to the high rates of noncontact and overuse hip and groin injuries in collegiate ice hockey athletes. OBJECTIVE To examine the effects of high, moderate, and low levels of sport specialization on subjective hip and groin dysfunction in collegiate ice hockey athletes. DESIGN Retrospective cohort study. SETTING Data were collected during the midseason of the 2018-2019 hockey season at a local ice hockey arena. PATIENTS OR OTHER PARTICIPANTS National Collegiate Athletic Association Division III and club ice hockey players from Midwestern college programs (n = 187; 81 women, 106 men). MAIN OUTCOME MEASURE(S) Participants were stratified into high-, moderate-, and low-specialization groups based on ice hockey participation before grade 9 of high school. The 6 subscales of the Hip and Groin Outcome Score questionnaire were used to assess current subjective hip and groin dysfunction. RESULTS The high-specialization group had lower scores than the low-specialization group on the Symptoms (P = .001), Pain (P = .003), Activities of Daily Living (P = .001), Sport and Recreation (P = .014), and Quality of Life (P = .002) subscales. The moderate-specialization group had lower scores than the low-specialization group on the Symptoms (P = .015) and Activities of Daily Living (P = .006) subscales. CONCLUSIONS Collegiate ice hockey athletes who were highly specialized before high school reported greater current hip and groin pain, symptoms, and dysfunction during activities of daily living and sport and recreation and lower current hip- and groin-related quality of life compared with low-specialization ice hockey athletes. Early ice hockey specialization may be detrimental to hip and groin function in collegiate ice hockey athletes.

[PMID: 31765062 DOI: 10.1111/edt.12531] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 11/22/2019] [Accepted: 11/22/2019] [Indexed: 12/30/2022]
Abstract
BACKGROUND/AIM Orofacial injuries are a serious problem in field hockey. The aim of this study was to determine the prevalence of orofacial injuries in field hockey players in Catalonia, the frequency of mouthguard use, the types of mouthguards used and the degree of interference with oral function. MATERIAL AND METHODS In this cross-sectional study, 325 field hockey players (28% women) from all age categories completed a questionnaire about orofacial injuries occurring during their sporting lives, including dental injuries, oral lacerations and episodes of acute temporomandibular disorder (TMD) pain. The questionnaire also asked about the experience of using a mouthguard, the type of mouthguard used and any adverse effects of use. The degree of interference with oral function was compared by type of mouthguard (mouth-formed, custom-made and pre-fabricated mouthguards) using the Kruskal-Wallis test. RESULTS Half of the players (50.2%) reported at least one orofacial injury during their sporting lives. The mean number of oral lacerations, TMD pain episodes and dental injuries were 1.59, 0.24 and 0.18, respectively. In total, 310 players (95.7%) had tried a mouthguard, and of these 269 (86.8%) and 283 (91.3%) still used a mouthguard habitually during training and competition, respectively. Only 11 players (3.5%) had tried all three types of mouthguards, and 71 players (22.9%) had tried two types of mouthguard. By type, 217 players (70.0%) had tried mouth-formed (boil-and-bite) mouthguards, 156 (50.3%) had tried custom-made mouthguards and 30 (9.7%) had tried pre-fabricated mouthguards. Custom-made mouthguards were rated as more comfortable than the mouth-formed type (P < .05). CONCLUSIONS The prevalence of orofacial injuries among field hockey players is relatively high. Most players habitually use a mouthguard during training and competition, typically preferring custom-made or a mouth-formed types. Custom-made mouthguards were considered the most comfortable.

Abstract
Injuries in men's elite ice hockey have been studied over the past 40 years, however, there is a lack of consensus on definitions of both injury and athlete exposure. These inconsistencies compromise the reliability and comparability of the research. While many individual studies report injury rates in ice hockey, we are not aware of any literature reviews that have evaluated the definitions of injury and athlete exposure in men's elite ice hockey. The purpose of this integrative review was to investigate the literature on hockey musculoskeletal injury to determine injury rates and synthesize information about the definitions of injury and athlete exposure. Injury rates varied from 13.8/1000 game athlete exposures to 121/1000 athlete exposures as measured by player-game hours. The majority of variability between studies is explained by differences in the definitions of both injury and athlete exposure. We were unable to find a consensus injury definition in elite ice hockey. In addition, we were unable to observe a consistent athlete exposure metric. We recommend that a consistent injury definition be adopted to evaluate injury risk in elite ice hockey. We recommend that injuries should be defined by a strict list that includes facial lacerations, dental injuries, and fractures. We also recommend that athlete exposure should be quantified using player-game hours.
