Abstract

The purpose of this study was to identify changes in the kinematics and kinetics of sprinting through the development of sprint performance in a male sprinter over four years. In the experiment, a male sprinter performed a 60-m sprint during which ground reaction forces and running motion were measured using a long force platform system and a motion capture system, respectively. The participant improved his 200-m personal record by 1.17 s over the four years. The characteristics of changes in the kinematics and kinetics of sprinting varied across the years. A decrease in knee extension torque during the support phase and an increase in ankle plantarflexion torque during the support phase were consistent throughout the development of maximal sprinting speed. These characteristics could serve as directions for training to improve sprint performance.
