| Research Abstract |
Denervation induced muscle atrophy was significantly suppressed by passive stretch for 15 min once daily stretching to the muscle though an upregulation of Akt/mTOR pathway. Extension of stretching duration for 15 to 30 min did not improve the suppression of muscle atrophy. However, increasing the frequency of stretching from once to twice daily improved the suppression of the atrophy. As no difference in the increased level of Akt phosphorylation in response to each stretching among different experimental groups, the improved suppression of atrophy in 15 min twice a day stretching group might arise from the increased frequency of Akt activation in this group. These results advance the development of a comprehensive program to suppress muscle atrophy for elderly or patients who do not have the ability to do strength training.
