| Research Abstract |
It has been well recognized that trainability for strength training varies depending on individual difference. In this study, we originally developed strength training model for rats and found that genetic strain difference exist for strength training. Sprague Dawley rat shows significant muscle hypertrophy with strength training but Wistar rats did not. We also found that mixture of different muscle contraction modes (isometric contractions and isometric contractions) and low frequency electrical stimulation are effective for muscle hypertrophy in Wistar strain with low response for strength training. Since electrical stimulation has been used in rehabilitation, low frequency electrical stimulation will be useful not only for low responder but for injured athletes.
