In this study, running motion was measured at 5 given velocity. The subjects of this study were high school middle-long distance players and non-players who participated with bare feet. To achieve this study, four video cameras and running timer were used. The object of this study was provided with a basic data for long distance runners’ record improvement. By using the statistics for specific variables and normalization of variable change curve, following conclusions were obtained. 1. It was appeared that players were more leaned forward as the velocity was increased than non-players at touch-down，mid-stance and lake off. 2. To some degree of velocity, the range of thigh rotation was increased and then was decreased. 3. It was thought that, players were smaller flexion averagely in shank of supporting phase than non-players at touch down and take off, while larger flexion at mid-stance. 4. Players were larger dorsiflexion in fool of supporting phase than non-players at touch down and mind-stance, while smaller dorsifiexion at take off.
