Abstract
The purpose of this investigation was to study the variation in ground reaction forces during take-off and to calculate the angular impulse produced about the center of mass by these forces during execution of a front aerial somersault. Additionally, several kinematic variables were discussed in relation to performance. Nine high level female gymnasts volunteered as subjects. Ground reaction force (GRF) patterns were monitored by a Kistler force platform and the selected kinematic variables were calculated from high speed film synchronized with the force records. Total body center of mass position was determined and subsequently used in the calculation of angular impulse during rear, double, and front leg support. While results showed similar angular impulse patterns across our subject population, a variety of kinetic and kinematic variables were presented in order to more completely discuss the components of angular impulse development during the take-off phase of a front aerial somersault. For example, while the mean angular impulse was 61.7 Nms (+/- 13.1), a surprising finding was the contribution made to this impulse by the rear leg, 70.9% (+/- 7.2).
