Study On The Suitable Falling Height Of Depth Jumping

Introduction:Depth jumping is one of the most classical training method of the plyometrics training, Suitable height of depth jumping due to athletes’sports projects and the level of training. This study through analysis of the athletes’strength and body shape, draw a regression equation that can be applied to each individual model, using regression equations can calculate each individual jump deep whereabouts fit height. The forecast models can be scientific, safe, effective monitoring of the depth jumping training intensity.Methods:This research through test20name sports professional men students of forces quality (lower limb half squatting forces, and place longitudinal jump) and body form (height, and weight, and lower limb long, and with tendon long,) of indicators, using Switzerland produced Kislter928KA type three dimensional test Taiwan test elongated-shortened cycle of time, using correlation analysis, and a Yuan linear regression analysis, and multiple linear gradually regression analysis, statistics method on data for processing.Conclusion:(1) Determine the maximum height of the drop jump deep practice evaluation. Standing vertical jump, weight and the relative strength influence the movement intensity of the depth jumping. The maximum height of depth jumping is closely linked with standing vertical jump performance.(2) established a forecast model for the suitable for falling height of depth jumping. By the maximum height of the drop jump exercises and the deep power of quality indicators, indicators of regression analysis of body shape, obtains standing vertical jump and the long of Lower limb may use for to test the male university student to jump the deep practice biggest whereabouts. Physical education male students to practice the maximum drop height of the depth jump prediction model:Y=2.897X the standing vertical jump performance-2.105X the long of lower limb+155.452。This model is suitable for this research to jump the links of deep exercise, whether to suitable for other links to await the further research and discuss concretely or not. Because this research institute takes a sample one is professional man university students, so the applicable scope of result of study is mainly the totality of the same level, whether to use professional athlete, women university students of sports and other sports enthusiasts in other levels or not, also await the further research and discuss.Suggest:(1) When a male college student Depth Jumping Exercise, Must ensure that the ability of muscle strength, speed-strength and balance requirements. He must be to ensure skilled sports technique and later for the contact.(2)Because of strength and body shape and Jump to practice appropriate to the whereabouts of the height of a relationship between, rather than functional relationship should be considered when forecasting model to predict the characteristics of the athletes.
