Takeoff The Effects Of Long Jump Special Practice Means And Technology Fusion Structure

Research purposes: in Asia, the developent of track and field career for a longtime,is one of the word’s front trank of hurdles, but skip class project still have somedifference with world level Best result of long jump of8.4m in our country, and theworld’s best result was8.95m, we can see there is a certain gap, I don’t have to thinkabout the reason, thus narrowing the gap between.Take-off technology is the core of long jump to technique, but the jumpingability it is very importment to the stand or fall of one of the key factors. Because itnot only is the athletes physical potential ability can be sustained and stabledevelopment, can play in the game level and sports life can be further extended and aseries of important issues. So better jump takeoff ability to ensure good results, but wejust still exist deficiencies in this respect, this is also our most athletes, especially theathletes in the game of run-up speed is relatively fast jump leaps Angle is low, seedand stretching Angle is relatively small, and so long. Based on the shannxi provivealtnletic administrative center jump movement of four athletes as the research object,to jump the analyses of kinematics and dynamics parameters in the structure, toachieve better effect of takeoff provide effective help.Research methods: literature material, expert interview method, questionnaire surveymethod, test method, mathematical statistics methodResearch results:1Special training for long jump athletes jumping exercises training methods,including: short run multiple step exercises, the short run multiple hop, jump a hurdlepractice to practice.2Takeoff pedal body kinematics analysis phase of the swinging leg swing speeddirectly affect the jump the moment of takeoff leg stretching movements from theground effect, and increase the body center of gravity in the process of take-offvertical velocity, the rise of body center of gravity height, his speed and long jumpresults have significant correlation. And swinging Angle of swinging leg to empty thebody center of gravity of high added value has a direct impact. It’s influence on thespeed of the takeoff speed and vertical leaps and achievement of important factor.3Through the dynamics analysis of continuous jump a hurdle because the level isrelatively slow, so in practice of Fz curve and Fx curve and the long jump take-offtechnology have obvious difference, but the continuous practice hurdle athletes forlower limb strength rising rapidly effect is obvious.
