Abstract Summary
In the aerobics, bouncing is a basic and essential movement for superior competition performance. Aerobic gymnastics in competition are required bouncing and jumping under rhythm restriction in music. It is so important to clear how athletes operate their limbs smoothly and effectively under limited time following music rhythm. The purpose of this work was to investigate kinematics and kinetics of knee and ankle joints affecting bounce in comparison of the mechanical characteristics between aerobic gymnasts and handball players as a control group.
