Different Load Continuous Vertical Jump On The In Situ Bio-mechanical Characteristics Of The Study

Athletes of vertical jumping ability is always the focus to athletes and coaches, good vertical jumping ability is the deciding factor in some sports . In the training process of vertical jumping and continuous vertical jumping are often taken as one of the most important technologies in sports. The Personal ability of vertical jumping is influenced besides genetic factors, the day after tomorrow training outside is also very important. Current research interests include the division of the phase terms of vertical jump, vertical jump theory of progress, vertical jump during the motion of each joint and the changes in momentum and power, vertical jump and sprint the other associated conditions such as sports, vertical jump process of lower limb EMG, blood lactate and other physiological change and so on. With the theory of continuous improvement vertical jump, vertical jump vertical jump training methods and means of continuous and more science. In order to obtain higher jumping ability of the body, often in the sports training using a variety of external loads of training. The load weight is a common way, for the weight of the current controversy in the academic community there is a large, and some scholars believe that the body in the training process 30% of their body weight load of the best training, and some scholars believe that the timing of the load weight of 60% body maximum output power, and some scholars believe that the body under its own weight only when the work to achieve maximum efficiency. With the improvement of the vertical jumping theory, The training methods of vertical jumping and continuous vertical jumping are becoming more scientific. In order to make the body get higher capacity, a variety of adscititious load of form be used in sports training. The current the research about the vertical jumping and loading on the vertical jumping has made many achievements for scientific exercise training and provides many important theoretical support. But continuous vertical jumping research is very little, furthermore,the research about loading on continuous vertical jumping is almost blank。We all know actual training or competition process, the pattern of continuous vertical jumping or single vertical jumping and continuous vertical jumping is more usual. So the study of influence about loading on continuous vertical jumping is more realistic significance. This article through the experimental method of 16 participants were loaded different loading (0kg, 20kg, 30kg,40kg) during continuous vertical jumping process. through the biomechanical characteristics of experimental data analysis and exploration aimed at the evaluation the ability of individual vertical jumping to provide training methods , theoretical and experimental basis. The conclude :First, in a continuous vertical jumping process, between different loads on the impact of gender there was no significant difference , there was the same trend of its parameters of different loads for men and women; Second, in the continuous vertical jumping process, loads changing in a certain range the minimum Angle value of knee joint little impact, there was no significant differences(p > 0.05). Also is certain load under continuous vertical jumping process ankle knee has good stability; Third, at different load under continuous vertical jumping process, in certain scope as load increases, knee, ankle angular velocity decrease gradually, there was significant differences(p < 0.05); Fourth, in different load under continuous vertical jumping process, vertical skipping cycle relatively stable, there was no significant difference(p > 0.05), Within the scope of certain and with the increase of load, supporting longer, post-flight shorter time, there was significant differences(p < 0.05); Fifth, in different load consecutive jumping process, lower limbs vertical rigidity coefficient K relatively stable, there was no significant differences(p > 0.05), Lower limbs type variables relatively stable, there was no significant differences(p > 0.05);Sixth, in different load consecutive jumping process, vertical force measurement machine by most strongly F relatively stable, there was no significant difference(p > 0.05), In certain scope as load increases, achieve the most greatly value the time needed for longer, there was significant differences(p < 0.05), Lower limbs explosive decrease, there are significant differences(p < 0.05).
