不同姿勢下對股四頭肌做離心收縮運動訓練對離心收縮之影響

Abstract

The purpose of this study was to evaluate the effect of quadriceps isokinetic eccentric trainingprogram at the strength of both concentric and eccentric strengths, as well as for the different eccentric training positions. Fifty-two normal subjects (26 male and 26 female), aged 21-32 year, were randomly assigned to a control group and two treatment groups. The first treatment group (n=18) trained in the sitting position and the second treatment group (n=18) trained in the supine position. They received quadriceps isokinetic eccentric training 3 times/week for 8 weeks. The control group (n=16) did not train but was tested at the same time as the treatment groups. Average force (in Newtons) of 3 concentric and of 3 eccentric quadriceps contractions on the KINCOM dynamometer at 60, 120 and 180°/sec was evaluated at the initial visit (pre-test) and two days after the last training session (post-test). Results showed that the treatment groups increased significantly (P＜0.05) in eccentric and concentric force at all test speeds with interaction effect between position and mode. However, eccentric isokinetic training of the quadriceps at 120°/sec is not mode specific for 60°/sec, 120°/sec and 180°/sec; and aiso not speed-specific for 120°/sec, 180°/sec. Different training positions of quadriceps at eccentric contractions make no difference in strength gains. There was no complaint of post-exercise soreness in this study through adequate warm up and cool down program in every session of training or evaluation.
