One of the reason that the aerobic dance is popular for korean women is that it is considered as a moderate aerobic exercise. However, high rate of aerobic dance related injuries have been reported among the participants. The purpose of this study was to estimate the impulsive load to the body while performing certain aerobic dance movement. Based on the preliminary questionairs on aerobic dance injury for 210 replyees, two aerobic dance movements including Run and High Kick were identified as high injury induced movements. The impulsive loads during aerobic dance estimated were joint angular acceleration and the vertical ground reaction force. The joint angular acceleration was determined using a 3-D cinematography technique, and the ground reaction force was measured with using an AMTI force platform system. It was founded that : the peak vertical ground reaction force 1738.7±171.2N, 1990.9±134.9N for Run, High Kick respectively. The peak vertical ground reaction force during High kick movement reached 3.7 body weight, which exceeded 3 body weight of force that can be experienced during jogging. These results indicates that although the aerobic dance movements look moderate means of exercise, certain movement ca produce highly impulsive look to the body and can aggravate injury when the movement is, kept repeated faster than the speed of healing process.
