Abstract

<p>It has been clarified that the combined use of blood flow restriction enhances the training load on skeletal muscle and provides additive hypertrophy and strength gain. Similarly, it has also been reported that the muscle hypertrophy could be enhanced in training in a hypoxic environment. In the present study, in order to compare the effects of exercise with blood flow restriction and exercise under hypoxia, and to examine the synergistic effect, resistance training in the right calf using an ultra-low intensity load was performed for 4 weeks using 4 conditions of control, blood flow restriction, hypoxia, and a combination of both, and the difference in their effects was examined by the response of growth hormone and changes in muscle strength and muscle mass. The growth hormone response before and after a single exercise before the training showed an increasing tendency but was not statistically significant, and after the training period, it tended to become even blunt, and there was no difference among the conditions. On the other hand, muscle strength increased significantly after training, and no difference among the conditions was observed. The results shows that there is no additional effect due to blood flow restriction or hypoxic environment, and combination of both in the training results.</p>
