This article reports on a pilot study of the loads exerted vertically by children when jumping. The subjects of the study were 17 children, aged from two to twelve years. Measurements were made using video recordings and a force-plate. The influence of the stiffness of the base and of jumping with and without shoes was investigated. Knee flexion, push-off force (thrust) and the ratio between push-off force and body weight (relative thrust) were analyzed. Measurements of the knee flexion showed a certain consistency for each child. The angle of knee flexion during push-off follows a bimodal distribution with maxima at 60° and 90°. The results for relative thrust suggest a close relationship between push-off force and body weight. |
