Abstract: Limited research has compared the physical qualities of adolescent rugby union (RU) players across differing playing standards. This study therefore compared the physical qualities of academy and school Under-18 RU players. One-hundred and eighty-four (professional regional academy, n = 55 school, n = 129) male RU players underwent a physical testing battery to quantify height, body mass, strength (bench press and pull-up), speed (10, 20 and 40 m), 10 m momentum (calculated 10 m velocity * body mass) and a proxy measure of aerobic fitness (Yo-Yo Intermittent Recovery Test Level 1 IRTL1). The practical significance of differences between playing levels were assessed using magnitude-based inferences. Academy players were taller (very likely small), heavier (likely moderate) and stronger (bench press possibly large pull-up plus body mass likely small) than school players. Academy players were faster than school players over 20 and 40 m (possibly and likely small), although differences in 10 m speed were not apparent (possibly trivial). Academy players displayed greater 10 m momentum (likely moderate) and greater IRTL1 performance (likely small) than school players. These findings suggest that body size, strength, running momentum, 40 m speed and aerobic fitness contribute to a higher playing standard in adolescent rugby union.

Abstract: Due to the complex systems nature of injuries, the responsibility for injury risk management cannot lie solely within a single domain of professional practice. Interdisciplinary collaboration between technical/tactical coaches, strength and conditioning coaches, team doctors, physical therapists and sport scientists is likely to have a meaningful impact on injury risk. This study describes the application and efficacy of a multidisciplinary approach to reducing team injury risk in professional rugby union. Observational longitudinal cohort study. Epidemiological injury data was collected from a professional rugby union team for 5 consecutive seasons. Following each season, these data informed multidisciplinary intervention strategies to reduce injury risk. The effectiveness of these strategies was iteratively assessed to inform future interventions. Specific ex les of intervention strategies are provided. Overall team injury burden displayed a likely beneficial decrease (-8% injury rate ratio (IRR) 0.9, 95%CI 0.9-1.0) from 2012 to 2016. This was achieved through a most likely beneficial improvement in non-contact injury burden (-39% IRR 0.6, 95%CI 0.6-0.7). Contact injury burden was increased, but to a lesser extent (+18% IRR 1.2, 95%CI 1.1-1.3, most likely harmful) during the same period. The range of skills required to effectively manage complex injury phenomena in professional collision sport crosses disciplinary boundaries. The evidence presented here points to the effectiveness of a multidisciplinary approach to reducing injury risk. This model will likely be applicable across a range of team and in idual sports.

Abstract: Student-athletes are subject to significant demands due to their concurrent sporting and academic commitments, which may affect their sleep. This study aimed to compare the self-reported sleep quality, quantity, and intrain idual variability (IIV) of students and student-athletes through an online survey. Student-athletes will have a poorer sleep quality and quantity and experience more IIV. Case-control study. Level 4. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while sleep quantity and IIV were assessed using the Consensus Sleep Diary. Initially, the PSQI and additional questions regarding sport participation habits were completed by 138 participants (65 students, 73 student-athletes). From within this s le, 44 participants were recruited to complete the sleep diary for a period of 14 days. The mean PSQI score was 6.89 ± 3.03, with 65% of the s le identified as poor sleepers, but no difference was observed between students and student-athletes. Analysis of sleep patterns showed only possibly to likely small differences in sleep schedule, sleep onset latency, and subjective sleep quality between groups. IIV analysis showed likely moderate to possibly small differences between groups, suggesting more variable sleep patterns among student-athletes. This study highlights that sleep issues are prevalent within the university student population and that student-athletes may be at greater risk due to more variable sleep patterns. University coaches should consider these results to optimize sleep habits of their student-athletes.
