Dynamic trunk strength of Canadian football players, soccer players, and middle to long distance runners

Abstract

Muscle strength data for sports which have varying demands on the trunk musculature are needed. The purpose of this study was to measure the trunk strength of three different sports groups of male varsity athletes and a recreationally active but nontrained group. Forty-six athletes (soccer: N= 16, Canadian football: N=15, and middle and long distance runners: N= 15) and 15 recreationally active subjects were studied. Three consecutive concentric and eccentric contractions through a range of 60°at an angular velocity of 30°per second (0.5236 rad/sec) were performed to measure the strength of the trunk flexors and extensors. Results showed peak concentric and eccentric flexor torque for footba..
