Outline of Final Research Achievements

The purpose of this study was to develop a training method to prevent hamstrings muscle strain injury during sports activities. We have measured the changes on morphology and function of each muscle when continuous hamstrings training intervention was performed, and investigated the relevance to the incidence of muscle strain injury. As a main results, a significant increase of hip extension torque and hypertrophy of the biceps femoris long head and semimembranosus muscle has found after the intervention only in hip extension training group. However, the effectiveness of hip extention training as hamstrings strain injury prevention has not been clarified since no strain injury has occurred in all subjects.
