This study investigated the relationships between pelvic behavior and impulse of ground reaction force as well as leg backward swing velocity during the acceleration phase and full speed phase of sprint running. Eleven male sprinters performed 30-m and 60-m sprints from a crouching start at maximal effort. Threedimensional motion analysis was performed to investigate the relationships between pelvic behavior and impulse of ground reaction force as well as leg backward swing velocity during the acceleration phase and full speed phase of sprinting running. The angular displacement of the pelvic free leg side lateral flexion in the frontal plane showed a significant positive correlation with the propulsion and vertical impulse during the acceleration phase. Also, the lumbosacral free leg side lateral flexion angular impulse showed a significant positive correlation with the propulsion and vertical impulse during the acceleration phase. Additionally, the lumbosacral free leg side torsion angular impulse showed a significant positive correlation with the peak value of the free leg backward swing velocity during the full speed phase. Therefore, the results obtained during the acceleration phase suggest that the pelvic free leg side lateral flexion was able to increase the propulsion and vertical impulse, whereas during the full speed phase, the pelvic free leg side rotation contributed to increasing the free leg backward swing velocity.
