Abstract

The purpose of this study was to determine the effects of the 12 weeks resistance exercise on torque-angle relationship of the knee flexor and extensor in healthy adults. 121 subjects were participated in this study(men: 67, women: 54). The participants performed 12 weeks resistance exercise and we were measured pre and post maximal voluntary isometric contractions at five knee joint angle(90, 70, 50, 30, 10). As for statistical verification, repeated measures ANOVA was conducted, and in case that there were significant differences in torque according to the changes in knee angle, contrast test for the rest of the knee angles based on peak angle was performed. Themaximal =torque was greater in the post-exercise than pre-exercise in all the knee angles(flexor, extensor & male, female) Torque-angle relationship of the knee flexor and extensor curve was inclined to make rather upward shift in the post-exercise than in the pre-exercise. However, there were no statistically significant difference between pre and post-exercise.
