Short-range Part Of The Two Men's Long Jump Athletes Downhill Run-jump Kinetic Effect Of Experimental Research

The author brought together the qualitative and quantitative research methods in this paper, including the literature review, specialist interview as well as utilizing the statistical manipulation on the experiment. A comparative analysis was carried out on the experimental parameters (the maximum wallop, takeoff time, the time index of extension, the force on the trough) of Slope 1o,2 o,3 o, and 4 o downgrade approach run and the all-length horizontal approach run . In accordance with the findings as follows, some suggestions were forwarded for practice purpose.Conclusion:I. Taking off by Slope 3 o downgrade approach run has effect on the ability of fast-take-off on the long jump. The takeoff time is approximating to that by the all-length horizontal approach run and should be regarded as one effective fast-take-off training method for the long jump.II. As for the ability training on the takeoff leg by the shorter approach run on the four slopes, the load on Slope 1 o,2 o,3 o and 4 o all approximate to takeoff load by the all-length horizontal approach run. The load is tuning up following the slope from 1 o up to 3 o, where Slope 3 o is the turning point, and the load on Slope 4 o is weaker than that on Slope 3 o. The finding will lay a foundation for our knowledge on the takeoff effect by approach run on different slopes.III. The experiment demonstrates that the optimal training is by Slope 3 o, which approximates to the takeoff ability and load requirements by the all-length horizontal approach run. Therefore Slope 3 o is a good variation for takeoff training as to enhance the practice consistency and intensity. Suggestions:I. The experiment is subject to the second-class male long-jump athletes. Subject to the small samples on the experiment, the generalization of the conclusion is limited and only for your reference.II. Although there is no experiment on the slopes above 5 o, we will infer the trends from the known statistics on the parameters that the training effect will not be better by higher slopes. Therefore, takeoff training by downgrade approach run on too high slopes will not be suggested.III. From the statistics, it is known that the parameters from some athletes are not in conformity with the whole samples, which indicates that downgrade training by different slopes have different effect on individuals. Therefore, individual difference should be considered in training.IV. For overload training, Slope 2 o and 3 o should be adopted as well as adding steps on the approach run so as to achieve a better training effect----the speed will approximate to or surpass the all-length horizontal approach run.
