Influences Of The Approach Level Speed Utilization Ratio On Take-off Speed Of The Male Broad Jumpers

Through substantial reading foreign literature Track and Field Series category, the collection of outstanding about Chinese and foreign athletes men's long jump run-up and take-off the relevant data, and both from the perspective of kinematics Comparative Analysis. the research discovered: The Chinese and foreign top athlete run the maximum speed to have the significance difference evenly, our country contestants for the atonement absolute speed low insufficiency, through raises the approach speed use factor the way to raise the approach speed. But stressed constantly the approach speed use factor the enhancement caused the approach speed to surpass the controllable scope, brought the disadvantageous influence to the taking off speed change. We may discover that our country athlete approach's maximum speed appears in approach's earlier period, then the time speed presents the obvious drop, indicated takes off the preparation period stage is not full, will like this create takes off the vertical velocity and taking off angle reduction. At the same time take-off stage of the technical parameters with foreign outstanding differences in a larger group, performance at the plate angle and off angle decreases and large fan-shaped area, which means that China's elite athletes run-up speed is too high utilization rate of take-off process has a negative impact, so that not a reasonable take-off speed.Carries on the analysis when to the Chinese and foreign top athlete's approach speed use factor, their physical quality existence certain difference, therefore to some technology's deficiency also cannot reflect completely,therefore through to the country first-level, the second-level long jump athlete carries on raises the approach speed use factor the experiment, and after testing the experimental group and control group's data carries on the contrastive analysis, may discover that after the approach speed use factor raises, if has broken the athlete to the speed controllable scope time, athlete's approach rhythm and took off the technology to have the change, mainly displayed in takes off the first ten meters speeds, final two step technical, the taking off speed and in the angle change. Through carries on the analysis to the domestic and foreign outstanding long jump athlete and the same physical quality's long jump athlete, will thus discover the approach speed use factor the unreasonable enhancement to have what kind of influence to the taking off speed.This article thought: The long jump athlete result's enhancement must maintain the high approach speed use factor, but the high approach speed use factor has not favored the result of the enhancement, should maintain at athlete oneself to the speed controllable scope, when raises athlete's approach speed use factor, regarding this must overcome brought the negative influence through the corresponding training, solely depends strengthens the athlete to take off ability is fast insufficient, but should also strengthen the athlete to the speed control. We must raise the athlete approach controllable speed the scope. This must further from strengthen the absolute speed the training is a premise, through enhances the approach technology and takes off ability to raise the approach speed the use factor, and can use the approach level speed reasonably the loss, thus enables the athlete the effective use approach speed, obtains the excellent result finally.
