China's Elite Female Sprinter Sprinter Full Speed Variation

Some years ago, it was accepted that the 100m Sprint meant simply an all-out effort from start to finish. Today this approach appears to be a definite reason for stagnancy in sprint performances and more attention has been paid to the correct distribution of effort over the 100m distances. With the development of science of sports, the performance of 100m sprint has more and more approached the utmost limits of capabilities in 100m sprint. Only realizing holistically the laws of variety of velocity in 100m sprint, can we continually improve the performance. In order to comprehend the actualities of the characteristics of variety of velocity of china elite women sprinters, we analyze contradistinctively the characteristics of the variety of speed using the data from the women who attended the women's 100m final in the 9th national sports meeting and from world elite women sprinters. We divide the course of 100m into many segments, and make an relative in-depth study in such problems as the exhibition of velocity capability in different segments, what percentage of the velocity in different segments (compared with the maximal velocity), the peak value of maximal velocity, the distance of the segment of maintenance of velocity and the percentage of decrease of velocity in this segment. By doing these, we want to present some useful data for the purpose of improving the performance of china elite women sprinters. We have gotten some useful advices. In the process of training and contest, we should carry out the notion of macrocosm in 100m sprint. Only by doing this, can we have a good chance of achieving excellent performance. According to the analysis, we have some conclusions:1. According to the characters of athlete, proper variety of speed in 100m Sprint is the external expression of the correct distribution of effort over the 100m distances, and is one of the pivotal factors to achieve excellent performance. There is a gap between World elite women sprinters and Chinese elite women sprinters in such matters as carrying out the notion of macrocosm in 100m Sprint and the correct distribution of effort over the 100m distances.2. We regard it is good for further study to identify 4 components: phase of initialacceleration, phase of secondary acceleration, point of maximal velocity, phase of maintenance of maximal velocity. There is much evidence in support of the partition.3. It has negative influences on postponing the fatigue of the system of nerve center, properly employ of energy resources, extending the distance of acceleration, the obtainment of maximal velocity, the maintaining of maximal velocity and the performance to bring into play extremely stride frequency. And this is one of the pivotal factors to retard Chinese elite women sprinter to achieve excellent performance.4. A high level of maximal velocity is not a guarantee but a precondition of an excellent performance. The performance in 100m sprint involves not only numerical value but more directly the quality of acceleration in the process of obtain maximal velocity, and the distance of passing with the sub-maximal velocity.
