The 2010 Winter Olympic Freestyle Skiing The Aerial Man Landing Stability Of Technical Analysis

Using the method of image measuring, to participate in the 2010 Vancouver Winter Olympics competitions of World Elite male athletes (GRISHIN Alexei gold medal Liu Zhongqing bronze medal winner) for the study, gets kinematic parameter of grounding techniques in freestyle skiing aerials, obtains the kinematics parameters on the basis of, such as Liu Zhongqing, GRISHIN Alexei data collation and correlation analysis, An athlete in theory clearly correct ground movement in the concept of freestyle skiing aerials, and trained as a theoretical reference for athletes. From inspection documents, freestyle skiing aerial ground-motion analysis and articles are rare, so for the rise and fall of freestyle skiing aerials for kinematics analysis has become an essential issue. Results from recent years, Gold Medal of the 2006 Winter Olympics in Turin, Han Xiaopeng, Li Nina Silver Medal of the Winter Olympics in Turin, Liu Zhongqing (I) bronze medal, and in freestyle skiing aerials events in China in recent years the rapid development of great red gold strength. This study primarily from players fell to the ground instantaneous, knee, hip and shoulder joints, such as an analysis of the angle and angular velocity, and noted that players landing instantaneous changes of body weight speed, pointed out that the 2010 Vancouver Winter Olympics gold medal winner in the contrast way GRISHIN Alexei differs with other athletes, training to athletes and coaches Guide to provide theoretical basis.In the end of this paper we come to the following conclusions:1. GRISHIN Alexei landed in complete action, hip joint technical LiuZhongQing send force obvious, the timing of the third weeks later completed, with a larger inertia left.2. GRISHIN from joint Angle analysis, Alexei LiuZhongQing can better than control the body in balance.3. Athletes should finish in 0.02-0.2 seconds initiative sends force, to ensure the process at the end of the third week of reasonable control air body posture and landed successfully sliding out.4. To obtain reasonable vertical speed and altitude, acquiring more fully emptied the completion of 3 weeks and ready to be landing, LiuZhong space in help slippery process keio horizontal speed increase.
