Objectives: To determine the incidence and characteristics of hockey ('field hockey') injuries over the course of one outdoor and indoor season. Comparisons of female versus male players, outdoor versus indoor season and match versus practice were performed.
Methods: Female and male teams of the first, second, third, regional and youth divisions were recruited among a local hockey association in Northern Germany, and followed over an indoor and an outdoor season. Exposure times and location, type, severity and cause of injuries during practice and matches were documented by the coaches or medical staff and collected weekly. Prevalence and incidence rates were calculated.
Results: Of the 232 players (mean±SD age 20.7±4.7 years, 68.1% male, 31.9% first division), 84 players (36.2%) suffered 108 new injuries during the season. The overall incidence rate was 3.7 injuries per 1000 player hours (95% CI 3.0 to 4.4). The injury incidence was lower in practice (2.7 per 1000 player practice hours, 95% CI 2.0 to 3.3) than in matches (9.7 per 1000 player match hours, 95% CI 6.8 to 12.7), and was similar for female and male players as well as during the outdoor and the indoor season. Most injuries affected the lower limb (thigh, knee and ankle) and occurred without contact (58.3%). Severe injuries (n=34; 31.5%) were predominantly located at the knee and hand/finger.
Conclusion: Hockey players have a high prevalence and incidence of injuries, especially at the lower limb.
