OBJECTIVES: The Irish Hockey League (IHL) introduced an eight-week winter break for the first time in the 2018/2019 season. We evaluated the effects of this eight-week break by comparing injury outcome metrics in the 2018/2019 (winter break) season and the 2017/2018 (no winter break) season.
DESIGN: Prospective cohort study.
METHODS: Each season was split into three distinct periods: period one consisted of the first nine weeks of each season; period two, weeks ten to 18; and period three, the final weeks. For the 2018/2019 season, the winter break was implemented in period two (weeks 10 to18). Relative risk with 95 % CI and injury incidence (1000h) were compared across the two seasons.
RESULTS: Overall, 173 and 150 injuries we incurred during the 2017/2018 (no winter break) and 2018/2019 (winter break season) seasons respectively. Compared to 2017/2018 season, total injury incidence rate, injury severity, and injury burden were all significantly higher in period three during the 2018/2019 season (i.e., following the winter break). Furthermore, injured athletes had a 2.5-times higher relative risk of sustaining an injury after the winter break. Relative risks of 15.3 and 21.4 were observed for lower back injuries and fractures after the winter break, when compared with no break.
CONCLUSIONS: Although fewer injuries were incurred during the 2018/2019 season, significantly more injuries were sustained in the period after the implementation of the winter break when compared to the corresponding period during the 2017/2018 season.
