Abstract
Sprint running and several types of jumping are associated with the stretch-shortening cycle (SSC). The purpose of this study was to investigate the relationship between anaerobic power during the SSC and sprint running performance. Method: After warming up, 66male university students performed a series of six successive vertical jumps (rebound jump) on a conductance mat, using their arms to help. The subjects then performed sprint running over 60m using a starting block on an all weather track. Anaerobic power during the SSC (rebound jump power) was significantly correlated with sprint running power (the ability to increase sprint running velocity) and peak sprint running velocity (r=0.672, 0.708, p<0.001). The present findings suggest that sprint performance is affected by anaerobic power during the SSC. Therefore, to improve sprint performance, strength training to increase anaerobic power output by the SSC should be taken into consideration.
