RESEARCH ON DIFFERENT SIZES OF PLATFORM'S EFFECTS ON THE ATHLETES' LEAVING PLATFORM SPEED IN THE FREESTYLE SKIING AERIAL

Abstract

The freestyle skiing aerial skill is an advantage project to win medals at the winter Olympic Games for China. This research applies the mathematical model method, combining theory with experiment, with the help of the athletes' leaving platform speed calculation software, to research and Analysis different sizes of platforms' effects on the athletes' leaving platform speed. The research result indicates that: the increasing of the platform height will decrease the leaving platform speed, and the decreasing range is related to the changing range. In order to ensure the specific actions' required leaving platform speed, it can be solved through adjusting the sliding distance and the speed of changing postures.
