Abstract

The purpose of this study was to examine the effects of aerobic exercise and low-frequency electrical stimulation on exercise capacity and muscle strength for healthy subjects. Subjects were divided into two groups; the group of only aerobic exercise (exercise group) :the combined training group of aerobic exercise and low-frequency electrical stimulation (combination group, n=6). Motor tasks were performed aerobic exercise in both group at the first two weeks. Four weeks thereafter the exercise group performed only aerobic exercise, the combination group performed aerobic exercise and low-frequency electrical stimulation. Then, two weeks thereafter, exercise group discontinued the exercise, the combination group were conducted only low-frequency electrical stimulation. The result, in the exercise group, ATV^^・O_2 showed a tendency to increase after 6 weeks. In the combination group, ATV^^・O_2 increased after 6 weeks and 8 weeks. PeakV^^・O_2 increased at 6 weeks. The right isometric knee extension strength increased after 8 weeks. In the combination group, ATV^^・O_2 tended high after 6 weeks than the exercise group and increased at 8 weeks than the exercise group. PeakV^^・O_2 of the combination group increased at 6 weeks and 8 weeks. As the results, in order to improve exercise capacity, it was suggested that the combination of aerobic exercise and low-frequency electrical stimulation had more possibility for the gain of exercise capacity.
