  abstract  = {Objectives Handball is associated with a high risk of overuse shoulder injury. This study investigated if an injury prevention programme effectively reduces overuse injury to the throwing shoulder of handball athletes. Methods 61 men's and women's handball teams (u-19 and senior athletes) were cluster-randomised into an intervention and a control group in the 2019-2020 season. Players of the intervention group regularly carried out an injury prevention programme. Both groups documented overuse shoulder injuries via an online questionnaire every second week. The primary endpoint was the prevalence of overuse injury to the throwing shoulder. Secondary endpoints were the influence of compliance on the primary endpoint and intensity of overuse shoulder symptoms measured by a shortened, handball-specific Western Ontario Shoulder Index (WOSI). Results 31 teams (295 players) in the intervention group and 30 teams (284 players) in the control group were included for analyses. The overall questionnaire response rate was 61\%. The average prevalence of overuse shoulder injury did not significantly differ between the intervention group (n=109, 38.4\% (95\% CI 32.9\% to 44.2\%)) and the control group (n=106, 35.9\% (95\% CI 30.7\% to 41.6\%), p=0.542). Compliance with the intervention programme did not significantly affect overuse shoulder injury (p=0.893). Using generalised estimating equations for WOSI, the estimated mean for the intervention group was 44.6 points (95\% CI 42.0 to 47.1) and 47.6 points for the control group (95\% CI 44.9 to 50.3, p=0.111). Conclusions A multicomponent exercise programme using rubber bands and stretching did not significantly reduce the prevalence or symptoms of overuse throwing shoulder injury in handball athletes of both sexes. Randomised controlled study; level of evidence I.},

  abstract  = {Introduction/Background Surfing, wind surfing and kite surfing enjoy a growing popularity with a large number of athletes worldwide. The aim of this study was to identify and compare the injury profiles and compare the injury profiles of these three extreme water sports. Materials and Methods These data for this retrospective cohort study were collected through an online standardised questionnaire during the 2017-18 season. The questionnaire included questions about anthropometry, skill level, injury diagnosis, injury mechanism, environmental conditions and training regimes. Results The 626 athletes included reported 2584 injuries. On average, each athlete sustained 4.12 injuries during the season. The most frequent injury location was in the lower extremity, in particular the foot, with 49 (16.4\%) injuries in surfing, 344 (18.3\%) in wind surfing and 79 (19.7\%) in kite surfing. Surfing demonstrated a particularly high rate of head injuries (n = 37; 12.4\%). Other frequent injury types were skin lesions (up to 42.1\%) and contusions (up to 40.5\%). The most common injury across all surfing sports was skin lesions of the foot (wind surfing: 11.7\%; kite surfing: 13.2\%; surfing: 12.7\%). In surfing, skin lesions of the head were frequently observed (n = 24; 8.0\%). In surfing, a 'too large wave' (n = 18; 24.7\%) was main cause of the injury, while in wind surfing (n = 189; 34.5\%) and kite surfing (n = 65; 36.7\%) 'own incompetence' led to the most injuries. Conclusion This unique study compares injury epidemiology and mechanism in the three most popular surfing sports: wind surfing, kite surfing and surfing. Overall, injuries were sustained mainly in the lower extremity, while surfing also demonstrated a high rate of head injuries.},

  abstract  = {Introduction Epidemiological injury surveillance in professional sports is often based on online media analysis in order to collect necessary data. However, the validation of this study protocol is lacking. Therefore, this study aimed to identify the validity of injury surveillance in men's professional team sports based on media reports. Methods In a retrospective cohort study, the validity of media-data-relating injuries was investigated in participating teams of the highest two German divisions in men's professional basketball (BB) and handball (HB) in the season 2018/2019. Injury protocols completed by the team physicians were compared to those of sports media injury reports. Results The study population was composed of 133 athletes (54 BB and 79 HB). Of 343 injuries reported by the team physicians, 151 (44\%) could be identified by means of sports media reports. Severe injuries (n = 75, 72\%) were reported more likely in sports media compared to less severe injuries (n = 76, 32\%, p < 0.00001). Odds ratio (OR) was 5.33 (95\% CI 3.22-8.82). No differences regarding injury reporting could be seen between the two team sports. Conclusion For severe injuries, media analysis may be a sufficient method for data collection in popular men's professional ball sports. An underestimation of true injury prevalence lies within the range of previous reported investigations concerning the validation of injury surveillance methods. Non-severe injuries could not be verified via media analysis in professional handball and basketball.},
