- Description: Objectives: Despite several consensus statements, different injury definitions are used in the literature. This study aimed to identify the impact of different injury definitions on the nature and incidence of complaints captured during a short-term running program for novice runners. Methods: 1696 participants completed weekly diaries on running exposure and musculoskeletal complaints during a 6-week running program. These data were used to compare six different injury definitions (presence of running-related pain, training-reduction, time-loss of.one day or one week). Injuries were registered under these different definitions. Consequently incidence and the nature of complaints were compared between definitions. Results: The different injury definitions resulted in incidences that varied between 7.5% and 58.0%, or 18.7 and 239.6 injuries per 1000 h of running. The median duration of injury complaints was 4-7 days for injuries registered under a 'day definition', while complaints registered under a 'week definition' lasted 20-22 days. For running-related pain injuries the median of the maximum amount of pain was 3.0. In training-reduction and time-loss injuries these median values were scored between 5.0 and 7.0. No significant differences in anatomical locations between injuries that were registered under a 'day definition' or a 'week definition' were found. Injuries registered under a time-loss definition were located relatively more often at the knee, while complaints at the pelvis/sacrum/buttock were captured more often under a running-related pain definition. Conclusions: Injury definitions largely impact injury incidence. Location of injury is also affected by choice of injury definition. This stressed the need for standardized injury registration methods. (C) 2015 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved. Groningen, Netherlands.

- Description: Objectives: To present the first comprehensive epidemiological profile of hospital-treated injuries sustained by female cricketers from 2002-2003 to 2013-2014 in Victoria, Australia. Design: Analysis of routinely collected hospital data (detailed case-series). Methods: A retrospective analysis of hospital-treatment data associated with cricket injuries sustained by women between 1 July 2002 and 30 June 2014, inclusive were extracted from databases held by the Victorian Injury Surveillance Unit in Australia. Results: Over the 12-year period, 668 cases were treated in Victoria. Of these, 547 were emergency department (ED)-presentations. There were 121 hospital-admissions, of which, the length of stay was <2 days for 78.5% cases. All cases were treated and released, and no fatalities were reported. The 10-14 year age group most frequently presented to ED (19.9%) and were most commonly admitted to hospital (16.5% of the total admissions). Fractures were the most common cause of hospital-admissions (47.1%) but only accounted for 17.2% of the ED-presentations. Dislocations, sprains and strains, were the most common (36.4%) cause of ED-presentations. The head was the most commonly injured anatomical location (27.8% of ED-presentations and 28.1% of hospital-admissions), followed by the wrist and hand (27.8% ED-presentations and 17.4% hospital-admissions). Conclusions: These findings provide the first overview of the nature of injuries requiring hospital attendance in female cricketers, and a foundation to inform the development of targeted injury prevention programs for female cricketers.

- Description: Objectives: 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. Design: Observational longitudinal cohort study. Methods: 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 examples of intervention strategies are provided. Results: 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. Conclusions: 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 individual sports.

- Description: Objectives: To assess the association between workload, subjective wellness, musculoskeletal screening measures and non-contact injury risk in elite Australian footballers. Design: Prospective cohort study. Methods: Across 4 seasons in 70 players from one club, cumulative weekly workloads (acute; 1 week, chronic; 2-, 3-, 4-week) and acute:chronic workload ratio’s (ACWR: 1-week load/average 4-weekly load) for session-Rating of Perceived Exertion (sRPE) and GPS-derived distance and sprint distance were calculated. Wellness, screening and non-contact injury data were also documented. Univariate and multivariate regression models determined injury incidence rate ratios (IRR) while accounting for interaction/moderating effects. Receiver operating characteristics determined model predictive accuracy (area under curve: AUC). Results: Very low cumulative chronic (2-, 3-, 4- week) workloads were associated with the greatest injury risk (univariate IRR = 1.71–2.16, 95% CI = 1.10–4.52) in the subsequent week. In multivariate analysis, the interaction between a low chronic load and a very high distance (adj-IRR = 2.60, 95% CI = 1.07–6.34) or low sRPE ACWR (adj-IRR = 2.52, 95% CI = 1.01–6.29) was associated with increased injury risk. Subjectively reporting “yes” (vs. “no”) for old lower limb pain and heavy non-football activity in the previous 7 days (multivariate adj-IRR = 2.01–2.25, 95% CI = 1.02–4.95) and playing experience (>9 years) (multivariate adj- IRR = 2.05, 95% CI = 1.03–4.06) was also associated with increased injury risk, but screening data were not. Predictive capacity of multivariate models was significantly better than univariate (AUCmultivariate = 0.70, 95% CI 0.64–0.75; AUCunivariate range = 0.51–0.60). Conclusions: Chronic load is an important moderating factor in the workload–injury relationship. Low chronic loads coupled with low or very high ACWR are associated with increased injury risk.
