The purpose of this study was to analyze how active and passive torques influence limb motion and to investigate, from a biomechanical point of view, the motor control mechanisms of the "Jump-slap-kick" in Chinese Martial Arts. Five well-trained Chinese Martial Arts players performed the "Jump-Slap-Kick". The Intersegmental dynamics analyses revealed that: 1.The dominant torques at the beginning of the support phase are created by knee flexor and hip extensor; at the middle of the support phase by plantar flexor, knee extensor and hip extensor; at the end of the support phase by the plantar flexor. 2.During the flight phase, the active muscle torque functions mainly to counteract the motion-dependent torque created by the mechanical interactions between limb segments. As the flight foot reversals from swing-up to swing-down, this counteraction reaches its maximum and is followed by a counteraction between muscle torque and gravitational torque.
