The Research On Rate Of Utilization In One Foot Jump And Stride For Outstanding Male Triple Jump Athletes In China

In this paper, fixed-point high-speed photography, video analysis and statistics as the main research method, the eleventh to participate in the 2009 National Games men's triple jump event for the elite athletes in the top five subjects were studied. it analysis the technical parameters after parsing, using biomechanics principles and mathematics, and compares the player with the International Elite Triple technical parameters. Found that the use of lower level speed and Single-hop, step jump higher level of speed loss for athletes in China,and we know that speed is the key decision to triple jump and cavort in the triple jump three times the horizontal distance of each hop in a large extent, depends on the level of speed, but also is one of the important factors for the total score of the Triple Jump. Also found that single-hop and jump take-off speed and stride off angle, arms and swing leg swing speed, two-leg jump landing cushioning and foot support loads with an instant and the position relationship between body weight, factors such as the proportion of triple jump horizontal velocity jump is caused by the loss of three key technical factors.Conclusions:1. One of the main factors leading to athletes backward is that absolute speed for male triple jumpers in China is less than the international elite athletes, Approach speed is an important indicator measuring and testing Run-up efficiency approach.he was among the athletes to keep the jump take-off velocity and horizontal displacement of the body the power to create outstanding results as well as the premise.2. Men's Triple Jump of about one foot from the Special Technical jump and leg stride jump off the ground phase of the buffer and kicking stages of technical indicators compared with the world's top athletes come to the ground technology and kicking techniques are different, and in the landing angle too small, the buffer affects the speed of long time use.3. Triple Jumpers in China in terms of one foot from the special ability to jump and stride jump off leg and swing leg phase angle large, the support legs is weak, prompting knee angle is small, kicking is not full, the buffer for a long time the use of the horizontal velocity.In view of this, the analysis of research and purpose in the search of the inherent laws and key technology of Triple Jump Technique, diagnosis on technical and provide a theoretical basis for the scientific training and reference values.
