Influence of High Intensity Pedaling-Training by Bicycle Ergometer on Muscle Function

The purpose of this study was to investigate effects of six weeks of high intensity pedaling-training on muscle function. Thirteen healthy adults participated in this study. Isokinetic muscle strength of the knee extensor and flexor, thigh circumference, body fat, anaerobic power, muscle thickness, fat thickness and the maximum oxygen intake were evaluated in this study before and after training. As a result, isokinetic knee extension torque at 60 deg/sec and 180 deg/sec and isokinetic knee flexion torque at 60 deg/sec increased significantly after six weeks of training. Thigh circumference showed significant increases, but thigh muscle thickness was not changed significantly. Anaerobic power was found to be significantly increased during the 6-week training period. However, there were no changes in body fat, fat thickness and maximum oxygen intake. It was suggested that high intensity pedaling-training was effective as muscle training.
