100m Technical Analysis Of Bolt

Explore the world's best 100m athletes'running time and space technology features and technologies division of support phase, can explore the technology that suitable for the development of contemporary sports technology style, provide advise for our country's sprint training and teaching.Also can provide guiding ideology and theoretical basis to improve the sprint theory and further study, to improve the technical level of sprint exercise, to catch the early realization of "dreams" purposes. In this study, the research object is the 2008 Olympic Games and 2009 World Championships men's, women's 100 meters final athletes. useing information technology-based method, download Video games by eMule VeryCD 0.48a Build 090304 Chinese software. use the fast feedback system dartfish software to obtain running time and space technology parameters in various support stage. Useing the Hero V9 software, obtained the number of steps,average cadence,average step length of all athletes by statistics method. each parameter and the athletes' heigt will conduct a comprehensive comparative analysis. The results show that:1. Combination of personal characteristics of the movement more individualized technical specifications are the technical features of today's sprint.2. Bolt's running technical support phase characteristics are conducive to the increase in running speed and with the running distance increase, the technology remains stable.3. Buffer and leg driving's division point is supported in the body center of gravity over the vertical position,and center of gravity, foot support points connected with the ground position angle of about 76.5 degrees; knee angle phase produced the smallest stage in the vertical support when it was about 0.01s.4. Bolt's successful move to reveal the inadequacies of today's selection of science, the future of the 100 meters Players are likely to develop in the direction to the tall athletes.5. Fraser high step frequency, low pace of technical features and Stewart high pace, low step frequency of the technical features will become the first Army women's 100m showdown highlights.
