Zusammenfassung
Drop jump, as one of the most popular plyometric exercise that involves stretch shortening cycle, has been proved very effective to improve vertical jump performance due to greater lower extremity power output. However, beyond optimal height, further increasing dropping height could not increase or even decrease power output. Our previous study has showed the approach run preceding the drop jump increased the power output further and decreased downward duration time and downward movement. The muscular activities associated with these changes were not clear. Therefore, the purpose of this study was to investigate the effects of approach run on the muscle activity of low extremity muscles.
