To examine the biomechanical profiles of the backward handspring, selected kinematic variables and angular momentum were caliculated in fourteen junior female gymnasts. The horizontal velocity of the gymnasts' center of mass decreased in the first stage of the foot support phase and in the first stage and the second half of the hand support phase. Angular momentum about the transverse axis through the gymnasts' center of mass increased in the second half of the hand support phase. Angular momentum, however, decreased in the first stage of both the foot support phase and the hand support phase. It was supposed that the decrease of horizontal velocity and angular momentum in the first stage of both the foot support phase and the hand support phase were caused by large angle of block in a direction opposite to the intended motion at touchdown.
