概要 The aim of this study was to clarify the relationship between the intensity of isometric contraction exercises (ICEs) and the facilitating recovery of atrophied muscles. The results indicated that the exercise load which is greater than a definite intensity activated myogenic satellite cells and increased the number of myonuclei compared to the normal cage activity or the low intensity exercise, suggesting that the activation of myogenic satellite cell would contributed to the increase of myonuclei number, resulting the rapid recovery of myofiber size in this study. The high intensity exercise caused muscle injury, and inhibited recovery of myofiber size. Thus, we conclude that an appropriate intensity of exercise load which not cause injury should be chosen for facilitating recovery from atrophy.
