Research On Technical Characteristics And Special Training Of Back Style High Jump

In this paper, by using the principle of the knowledge of sports biomechanics and further study of fosbury style high jump movement leaped over the process of the bar in the human body. Focusing on the analysis of human body when a rod movement direction, Angle and air body movements. Select high jump athletes in today’s China’s most powerful deng, wang yu, Peter huang, wangchen four people in the high jump bar in the whole process of parameter and technical characteristics of body movement, sorting out data associated with a rod movement parameters as a reference standard. And department of shaanxi normal university sports institute movement Zhong Yaquan, xiao-zhao li, Hu Junfeng, zhang xu, the four jumper test and measurement, obtain parallel statistics and analysis of mechanical parameters, to delve into the human body in the high jump movement when a rod body movement to provide effective basis. Focus on collecting and analyzing the athletes in the process of a rod body each link rod instantaneous time, the height value in fosbury style high jump, his horn, and highest point of the center of gravity and rail horizontal distance. Analysis results show that the removal of the athletes difference (height, weight, quality and other factors) outside the single analysis from the perspective of a rod technology, our four athletes in a bar when the body’s Angle, the utilization rate of H2 and H3 index comparatively large difference which showed that the two groups of players on a pole technology gap, to extract the four national team athletes do pole technology advantages as a reference standard. This paper emphatically analyzes the technical features of two groups of athletes and contrast differences to find out in line with the technique of sports biomechanics, and the design is similar to a technical lever and conform to the training methods of sports biomechanics.The results of the study:1:li xiao-zhao H1 value most; Zhong Yaquan minimum. Zhong Yaquan H2 maximum; li Xiao-zhao and Hu Junfeng minimum; Zhong Yaquan H3 minimum; Other athletes. Zhong Yaquan and zhang xu, the height of the highest utilization rate; Hu Junfeng minimum.2:Hu Junfeng billowed from Angle of the clock and the right to a minimum, the other two players buckled up Angle were similar, xiao-zhao li, Hu Junfeng body centre of gravity and the level of the rail distance the king Zhong Yaquan minimum, li xiao-zhao and zhang xu, in a moment the body center of gravity highs cleared the bar to appear behind the bar, the rest of the athletes gravity highs in the front of the bar.3:zhang xu in the empty bar back arch action is not sufficient, Hu Junfeng lever in empty head didn’t get it right back.4:four high jumpers did not make fuii use of arm swing to improve the efficiency of the rod.Conclusion and suggestion:1:in the process of fosbury flop a lever, head full back action to drive the body the body achieve maximum force around the body shape of frontal axis rotation, xiao-zhao li, Hu Junfeng should strengthen the physical feeling of practice in the air.2:a lever arm swinging can make human body to form two axis, the effect of four athletes in a bar in this paper, the experimental group without swing arm is used to improve the efficiency of a rod.3:on the lever back bow form of compensatory body movement increases the space of a pole, in this paper, four research object all needs to strengthen the training of the back arch action compensatory body movement effect into full play.4:design core strength training means, strengthen the core strength training group four athletes...
