Biomechanics Mechanism of Landing Buffer for Freestyle Skiing Aerials Athletes

The force of Landing for Freestyle Skiing Aerials Athletes is very large, which is dangerous for the athletes. The aim of this paper was to prevent the damage on the athletes and improve their Landing stability. The instruments of this paper were shown below. Switzerland KISTLER force platform and 2 American TROUBLESHOOTER high-speed cameras worked synchronously. 6 Freestyle Skiing Aerials fell onto the ground from the height of 50cm with the posture of normal and whole sole. The landing buffer time, standard force values, gradient force value, center of pressure, body slant angle and the changes of lower limb joint angles were analyzed. The maximal impact force of landing under the height of 50cm was 1. 44 times larger than normal landing, which was probablt to get the athletes injured. The central pressure of front and back direction was smaller. The body slant angle was larger and the turning torque smaller, and therefore the body stable.
