| Research Abstract |
Strength training with low load in combination with vascular occlusion, named Kaatsu training, increases muscular size and strength similarly to conventional, heavy resistance training. The aim of the present study is to know the effects of ischemia and cyclic stretch on the proliferation of cultured myoblasts. The obtained results suggest that activated satellite cells are damaged by hypoxia and reperfusion, and that the proliferation rate increased as a result of recovery from the damage. Furthermore, the moderate training with 10% cyclic strain enhances cell proliferation during the recovery process.
