By using the movement analysis system, the authors carried out a 3D kinematic analysis on the Ilyushin movement completed by such 2 excellent competitive aerobic athletes in the world as YU Yang-yang and Suwabe respectively by using the ipsilateral and contralateral arm swinging techniques, and revealed the following findings: as compared to the ipsilateral arm swinging technique, as for the athlete who used the contralateral arm swinging technique in the turning phase, the body swinging plane was closer to the target sagittal plane (P<0.001), the peak value of the included angle formed by the swinging leg and the supporting leg in-creased significantly (P<0.01), the included angle formed by the upper torso and the supporting leg decreased sig-nificantly (P<0.001); as for the inclination angle of the body mass center and sole pressure center, the rang of back and forth swinging decreased significantly (P<0.001), the rang and correction of left and right swinging decreased sig-nificantly (P<0.01, P<0.001). The said findings indicate that using the contralateral swinging technique is conducive to the athletes moving the body and limbs to the target position and maintaining better balance.
