| Outline of Final Research Achievements |
In this study, we investigated the effects of stretching intensity and stretching capacity (stretching intensity x time) on muscle stiffness reduction. Specifically, we focused on the relative intensity of stretching between individuals, the intensity of stretching within individuals, and the capacity of stretching under uniform conditions. The results revealed that stretching intensity was an important factor in the reduction of muscle stiffness. However, it was also found that stretching intensity may differ depending on the muscles being stretched, and it is necessary to clarify the importance of stretching intensity for different muscles and subjects in the future.
