AN EVALUATION OF PERFORMANCE OF A DOUBLE-LEG CIRCLE ON A POMMEL HORSE, AND A DESIRABLE PERFOMANCE PROPOSAL

For the evaluation of the performance of a double-leg circle on a pommel horse, we focused on the relation between the horizontal rotation of a body about the vertical axis in the center of a pommel horse and the hip rotation about the longitudinal axis of a body. Several gymnasts having different levels of skill were examined by using a motion capture system. The analysis shows that the horizontal rotation and the hip rotation are in good synchronization for the performance of a well-trained gymnast
