Injury epidemiology in the men’s and women’s Spanish rollerhockey league: a descriptive study / Epidemiología lesional en la liga española de hockey patines masculina yfemenina: un estudio descriptivo

The purpose of the present study is to describe the injury patterns among male and female athletes of the Spanish Rink hockey league. A cross-sectional study was performed, concerning the time-loss injuries (the athlete is prevented to participate in a training session / game because of the injury registered by the medical staff of every team. 137 athletes were included (98 male, age 26.7 ± 5.9 years; 39 female, age 23.3 ± 4.6 years). Ninety-four time-loss injuries were recorded, being the most frequent the muscle injury (38 episodes, 40.4%), especially the ones affecting the adductor longus muscle (23 episodes, 60,5% of the muscle injuries). The majority of the registered injuries were classified as mild (1-7 days of time-loss) but the and the median return-to-play was 19.4 ± 29.6 days. Eight episodes of reinjury were described (8.5% of total injuries) and 2 injuries required surgical treatment (2.1% of total injuries). Concerning female athletes, we can highlight a increased number of ligament injuries in the lower limbs compared with male athletes and the absence of tendinopathies causing time-loss. The knee injuries were the injuries with a higher return-to-play in goalkeepers. The present study is the first to describe the injury patterns among rink hockey elite athletes and must set a starting point to study and prevent injuries in this sport.(AU)

El propósito del presente estudio es describir los patrones lesionales durante una temporada de los deportistas de la máxima competición masculina y femenina de Hockey Patines en España. Se realizó un estudio descriptivo de las lesiones con baja deportiva (el/la deportista no puede participar como mínimo en un entrenamiento o partido debido a la lesión) recogidas por los equipos biomédicos de cada equipo. Se estudiaron 137 deportistas (98 hombres, con una media de edad de 26,7 ± 5,9 años y 39 mujeres con una media de edad de 23,3 ± 4,6 años) Se recogieron un total de 94 lesiones con baja deportiva, siendo las más frecuentes las lesiones musculares (38 episodios, 40,4% de las lesiones totales), en especial del músculo aductor largo (23 episodios, 60,5% de las lesiones musculares). La mayoría de lesiones registradas fueron leves (1-7 días de baja deportiva) aunque el tiempo medio de baja fue de 19,4 ± 29,6 días. Se recogieron 8 episodios de relesión (8,5% de las lesiones totales) y 2 lesiones que precisaron tratamiento quirúrgico (2,1% de las lesiones totales). Al estudiar a las deportistas femeninas destaca que presentaron un mayor número de lesiones ligamentosas de extremidades inferiores en comparaciones con los varones y no se describió ningún episodio de tendinopatía.Al estudiar las lesiones específicas de los porteros/as se evidenció que las lesiones que causaban más baja deportiva eran las lesiones de rodilla. El presente estudio es el primero en describir las lesiones en jugadores/as de primer nivel de hockey patines y debe marcar un punto de partida para el estudio y prevención de las lesiones en este deporte.(AU)

Epidemiology of Overuse Injuries in US Secondary School Athletics From 2014-2015 to 2018-2019 Using the National Athletic Treatment, Injury and Outcomes Network Surveillance Program.

CONTEXT: With 8 million annual US high school student-athletes, the epidemiology of sport-related injuries has garnered significant interest. The most recent studies examining overuse injury rates in high school sports were based on data from 2012 to 2013 and, therefore, may not reflect current overuse injury rates in high school sports. OBJECTIVE: To (1) determine overuse time-loss (TL) and non-time-loss (NTL) injury rates among high school student-athletes using National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) data collected from 2014-2015 to 2018-2019 and (2) compare overuse injury rates based on student-athlete sex defined by whether it was a boys' sport or a girls' sport, the sport itself, and the injury location. DESIGN: Descriptive epidemiology study. SETTING: Online injury surveillance from 211 high schools (345 individual years of high school data). PATIENTS OR OTHER PARTICIPANTS: Athletes who participated in secondary school-sponsored boys' or girls' sports. MAIN OUTCOME MEASURE(S): Boys' and girls' overuse injury data from the NATION-SP during the 2014-2015 to 2018-2019 school years were analyzed. Overuse injuries were identified using a combination of the reported injury mechanism and diagnosis. Time-loss injuries resulted in restriction from participation beyond the day of injury; NTL injuries did not result in restriction from participation beyond the day of injury or involved no lost time due to the injury. Injury counts, rates, and rate ratios (IRRs) were reported with 95% CIs. RESULTS: The total overuse injury rate was 5.3/10 000 athlete-exposures (AEs; 95% CI = 5.1, 5.7), the NTL overuse injury rate was 3.4/10 000 AEs (95% CI = 3.1, 3.6), and the TL overuse injury rate was 2.0/10 000 AEs (95% CI = 1.8, 2.2). The overuse injury rate was greater in girls' sports compared with boys' sports (IRR = 1.9; 95% CI = 1.7, 2.1). The highest rates of overuse injury were observed in girls' cross-country (19.2/10 000 AEs; 95% CI = 15.0, 24.2), girls' track and field (16.0/10 000 AEs; 95% CI = 13.5, 18.8), and girls' field hockey (15.1/10 000 AEs; 95% CI = 10.2, 21.6). Overuse injury rates were higher for the lower extremity than the upper extremity (IRR = 5.7; 95% CI = 4.9, 6.7) and for the lower extremity than the trunk and spine (IRR = 8.9; 95% CI = 7.3, 10.8). CONCLUSIONS: Awareness of the overuse injury risk, as well as prevention and intervention recommendations, is necessary and should be specifically targeted at cross-country, field hockey, and track and field athletes.

Epidemiology of Lower Leg Soft Tissue Injuries in High School Athletes.

BACKGROUND: Annually there are an estimated 4.5 million sports- and recreation-related injuries among children and young adults in the United States. The most common sports-related injuries are to the lower extremities, with two-thirds occurring among children and young adults (age range 5-24 years). The objective is to describe the epidemiology of lower leg injuries across 27 high school (HS) sports over a 3-year period. METHODS: The Datalys Center for Sports Injury Research and Prevention provided lower leg injury data for 27 sports in 147 high schools for 2011-2012 through 2013-2014 academic years from National Athletic Treatment, Injury and Outcomes Network (NATION) HS Surveillance Program. RESULTS: The overall rate of lower leg injuries over this 3-year period was 1.70 per 10 000 acute events (AEs) (95% CI, 1.59-1.82). In men, the highest number of lower leg injuries was in football (n=181), but indoor track had the highest rate of injury at 2.80 per 10 000 AEs (95% CI, 2.14-3.58). In women, the highest number of lower leg injuries and the highest rate of injury were in cross-country (n=76) at 3.85 per 10 000 AEs (95% CI, 3.03-4.81). The practice injury rate was 0.91 times the competition injury rate (95% CI, 0.78-1.07). CONCLUSION: An improved understanding of the most common sports in which lower leg injuries are seen may help direct appropriate resource utilization. Our data would suggest efforts toward prevention of these overuse injuries, especially in football, track, and cross-country may have the greatest impact on the health of student athletes. LEVEL OF EVIDENCE: Level IV, case series.

Characteristics of Injuries Occurring During Cross-Country: A Report from the Athletic Training Practice-Based Research Network.

CONTEXT: Cross-country is a popular sport activity, particularly in adolescent populations. Although epidemiologic investigations have provided insight into patient and injury characteristics associated with running injuries, little is known about how these injuries are managed at the point of care. OBJECTIVE: To describe injury and treatment characteristics of injuries sustained during cross-country. DESIGN: Cross-sectional study. SETTING: High school athletic training clinics within the Athletic Training Practice-Based Research Network. PATIENTS OR OTHER PARTICIPANTS: Patient cases were included if the patient was diagnosed with an injury that occurred during interscholastic cross-country participation. All patients received usual care by an athletic trainer. MAIN OUTCOME MEASURE(S): We used summary statistics to describe injury (sex, age, participation level, time of injury, mechanism of injury, body part, injury type, diagnosis) and treatment (type, amount, duration, number of services) characteristics. RESULTS: Most cross-country injuries occurred to the lower extremity and were musculotendinous or ligamentous in nature. The most common injury types were sprain/strain (43.8%), tendinopathy (18.5%), and general pain (9.5%). Injured body parts and diagnoses were typically similar between sexes. The most frequently used treatment was therapeutic exercises or activities (28.7%), and patients received an average of 7.4 ± 17.4 total athletic training services during 5.5 ± 15.1 episodes of care over 27.8 ± 87.5 days. CONCLUSIONS: Adolescent cross-country student-athletes frequently sustained non-time-loss injuries that required up to 1 month of treatment and management. These findings will generate awareness surrounding the role of athletic trainers in providing care for cross-country athletes.

The impact of all-rounders and team injury status on match and series success in international cricket.

The association between injury status of the team and all-rounders on match outcome were investigated in international cricketers. Time and non-time loss injuries were recorded over a 32-month period in 47 senior international cricketers. Team injury status was expressed on a 1-4 scale from "fully available" to "unavailable". Generalised linear model (GLM) was employed to examine whether team injury status and the injury status of all-rounders (AR) and single skill (SS) players was associated with the outcome of the match or series. A significant association between team injury status and match and series outcome was found. Team mean injury status was 12.0% lower (P < 0.001; ES = 1.06) during successful series wins and 7.8% lower (P < 0.001; ES = 0.66) during successful match outcomes. Skill group injury status was also significantly associated with match (P = 0.001) and series (P = 0.001) outcomes with AR exhibiting greater injury status than SS cricketers (P < 0.001, ES = 0.44). All injuries, irrespective of time lost, influence the outcome of international cricket series' and matches with injuries to AR having a higher impact on the results. The findings will impact on the injury prevention strategies in elite cricket.

Effects of the FIFA 11+ on injury prevention in amateur futsal players.

OBJECTIVE: To examine the effectiveness of the FIFA 11+ in reducing injury in futsal players. METHODS: Ninety-one male futsal players from six amateur futsal clubs were recruited and assessed for eligibility, and 71 were randomized to the 11+ group (n = 37, age: 27.0 ± 5.1 years) and a control group (n = 34, age: 26.0 ± 5.1 years). The 11+ program was executed twice a week for 20 weeks, separated by a 10-week period where both groups executed their regular warm-up. Data on match, training exposure, and injuries were recorded during the regular season. RESULTS: The players sustained a total of 58 injuries during the futsal regular season, with 24 injuries in the 11+ group and 34 injuries in the control group; the overall incidence of injuries per 1000 player-hours was significantly higher in the control group (11.6 vs 6.5; mean difference (95% CI) -5.1 (-9.1 to -1.1), P = .014). The 11+ group had a significantly lower incidence of acute (11.2 vs 5.7; -5.5 (-9.4 to -1.6), P = .007) and lower limb (8.7 vs 4.4; -4.2 (-8.1 to -0.4), P = .032) injuries per 1000 player-hours. Players from the control group had a higher number of days injured (20.4 ± 17.3 vs 10.5 ± 9.1, P = .036). CONCLUSION: The FIFA 11+ is an injury prevention program suited for injury reduction in amateur futsal players, as it reduces the incidence of overall, acute, and lower limb injuries during the season.

The Epidemiology of Overuse Conditions in Youth Football and High School Football Players.

CONTEXT: High-intensity sport training at the youth level has led to increased concern for overuse conditions. Few researchers have examined overuse conditions in youth sports. OBJECTIVE: To examine the rates, risks, and distributions of overuse conditions between youth and high school football players. DESIGN: Descriptive epidemiologic study. SETTING: Youth and high school football teams. PATIENTS OR OTHER PARTICIPANTS: The Youth Football Safety Study (YFSS) investigated youth football athletes from age 5 to 14 years. The National Athletic Treatment, Injury and Outcomes Network (NATION) focused on high school football athletes 14 to 18 years old. The YFSS data consisted of 210 team-seasons, and the NATION data consisted of 138 team-seasons. MAIN OUTCOME MEASURE(S): Athletic trainers collected football injury and exposure data during the 2012 and 2013 seasons. Injury rates, risks, and distributions were calculated, with injury rate ratios, risk ratios, and injury proportion ratios with 95% confidence intervals (CIs) comparing youth and high school football players. RESULTS: The YFSS reported 1488 injuries, of which 53 (3.6%) were overuse conditions. The NATION reported 12 013 injuries, of which 339 (2.8%) were overuse conditions. The overuse condition rate did not differ between high school and youth football (3.93 versus 3.72/10 000 athlete-exposures; injury rate ratio = 1.06; 95% CI = 0.79, 1.41). However, the 1-season risk of overuse condition was higher in high school than in youth football players (2.66% versus 1.05%; risk ratio = 2.53; 95% CI = 1.84, 3.47). Compared with high school football players, youth football players had greater proportions of overuse conditions that were nontime loss (ie, <24 hours participation-restriction time; 83.0% versus 67.0%; injury proportion ratio = 1.24; 95% CI = 1.07, 1.43) and affecting the lower extremity (92.5% versus 62.5%; injury proportion ratio = 1.48; 95% CI = 1.32, 1.65). CONCLUSIONS: Overuse conditions may not present a primary concern in youth and high school football players. However, differences existed between the 2 levels of competition. Although additional research on the incidence of overuse conditions across all youth and high school sports is needed, these findings may highlight the need for programming that is specific to competition level.

Obesity as a Possible Risk Factor for Lost-time Injury in Registered Nurses: A Literature Review.

Time-loss injuries are still a major occurrence in Canada, injuring thousands of Canadian workers each year. With obesity rates on the rise across the country, as well as around the world, it is important that the possible effects of obesity in the workplace be fully understood, especially those effects linked to lost-time injuries. The aim of this paper was to evaluate predictors of workplace lost-time injuries and how they may be related to obesity or high body mass index by examining factors associated with lost-time injuries in the health care sector, a well-studied industry with the highest number of reported time loss injuries in Canada. A literature review focusing on lost-time injuries in Registered Nurses (RNs) was conducted using the keywords and terms: lost time injury, workers' compensation, occupational injury, workplace injury, injury, injuries, work, workplace, occupational, nurse, registered nurse, RN, health care, predictors, risk factors, risk, risks, cause, causes, obese, obesity, and body mass index. Data on predictors or factors associated with lost-time injuries in RNs were gathered and organized using Loisel's Work Disability Prevention Management Model and extrapolated upon using existing literature surrounding obesity in the Canadian workplace.
