Prospective Study of Concentric and Eccentric Leg Muscle Torques, Flexibility, Physical Conditioning, and Variation of Injury Rates During One Season of Amateur Ice Hockey

Abstract

Twenty-three male ice hockey players in a third division amateur ice hockey team were prospectively studied during the 1987-1988 season. O₂ uptake, muscle flexibility, and isokinetic concentric and eccentric leg muscle strength were measured before and after the season. All injuries were recorded by one and the same physician attending all the games: 68 injuries occurred altogether but only six of these led to absence from training or matches. O₂ uptake and muscle flexibility were unchanged during the season, but a significant drop of both concentric and eccentric quadriceps and hamstring torques occurred in spite of the fact that the team played two games and trained twice per week during the entire season. No correlation between the fall in muscle strength and the injury rate was found. Although many injuries occur in ice hockey, the majority are minor ones that do not lead to absence from playing.
