 note = {This study investigated the biomechanical analysis of sprinting performance for preschool children. The subjects were 77 preschool children who aged 3 to 6. They were filmed in VTR picture during 25m sprinting, with a pole located every 5m. Using the VTR pictures, average speed; stride frequency; stride length between the start point and the marked distance point of each were calculated. The results obtained were as follows:
1 The sprinting velocity cause by height, and by stride length in preschool children. On the other hand, stride frequency is not related to height.
2 It was suggested that the sprinting velocity was greatly related to stride length and stride length ratio, and also weakly related to the stride frequency.
3 Times of 25m sprinting were decreased from 3 to 5 years for both boys and girls.
4 It was suggest that both boys and girls reached the highest for sprinting velocity in the 5-20m section, and the decrease in sprinting velocity decreased for the stride frequency after 10m and for the stride length after 15m, text, application/pdf},
