The effects of a seven-week isokinetic training program on eccentric strength development

Abstract

This study examined the effects of a 7 wk eccentric isokinetic training program (60 degrees/sec) on peak torque (PT), total work (TW)and peak torque/body weight (PT/BW) of the knee extensors. Thirty-one men and women from the University of Wisconsin- La Crosse physical education and physical therapy classes participated in the study. Ss were tested for strength on the KIN-COM at 60 degrees/sec and 180 degrees/ sec, pre and post a 7 wk training program. The experimental group (20 Ss)performed 3 sets of 10 repetitions of eccentric knee extensions at 60 degree/sec 3 times a wk for 7 wks. The control group consisted of 11 Ss. A t-test for independent samples of mean differences between the 2 groups was done ti determine if the training program would cause a significant increase in strength at both slow and fast velocities.
