Abstract

The purpose of this study was to investigate differences in the joint kinetics of the kip maneuver of the horizontal bar between ten skilled and three unskilled subjects. The kip maneuvers were videotaped with a VTR camera to obtain biomechanical data by a motion analysis technique. Kinematic characteristics of the skilled subjects were the straight body position and longer distance between the CG and the bar during the forward swing. The shoulder joint torque power of the skilled subjects under the bar was larger than that of the unskilled ones. The peak of the hip flexion power of the skilled subjects was later than that of the unskilled ones. The results suggested that the timing of motion is essential in the kip maneuver, and that the unskilled subjects should emphasize the hip flexion in later timing after the reversal point.
