Research On The Effect Of Basic Long Jump Ability By Using The End Of Mulitiple Joint Conbined Of Pedal And Stretch Strengh Training

Nowadays, Strength training receives extensive attention. It is recognized that to improve the nerve-muscle system function, enhance muscle contraction strength, is one of the most direct and important way to improve athletic performance. Therefore, Almost all the competitive sports, Whether it is relying on physical force as the class project or Technology and flexible non-physical class of items. And those what are characterized with skills and tactics of the group class projects. They all have paid high attention to the strength training and research. Strength training can stimulate the muscles and nervous system to increase its strength effectively. Different Strength training exercises will causes different muscle exercise effect. We found the following problems in many sports by means of daily training and leg kicking action on the anatomical study and preliminary tests on the handling of incomplete data:1,with the speed of kicking leg's lower and the extension of angle joints's increase, The muscle strength of human hip, knee, ankle decreased significantly.2. After Athletes in the knee angle greater than 120°, The level of muscle strength is in a low situaiton. Even if the angular velocity of knee extension has started to diminish, but the muscle strength still did not increase. The same problem exists in the hip and ankle of stretching process.3, under limited conditions, What exclude kicking late caused by the inertia factors. The level of muscle strength is still low. Combining these problems found. This study of the current use of lower extremity strength training methods of back kicking analysis:1, The commonly used forms of barbell exercises and the front kicking action in sitting position have the problem of low special similarity structure to the aciton,which is not good to overcome the impact of dynamic load inertia. With the knee angle increased to a certain extent, the load to limbs decreases; 2, although the jump and back step closer to the action itself, but its very difficult to continue to increase workload intensity and control implementation.Based on the above issues, this study propose the strength training methods of the end kicking, by combining the basic jumping long jump to the end of experiments to verify the kicking strength training (?)wer limb forces. The results showed that:After the experiment, two groups of standing long jump, standing triple jump, standing vertical jump test indicators have improved in both the maximum power increase, statistically significant differences before and after. Through the experimental group after training, standing long jump increase 7% compared with before training; the control group standing long jump increase 4%. Standing triple jump the experimental group increased by 8%; the control group increased 3%. Standing Vertical Jump experimental group increased by 27%; the control group increased 17%.The performance by the three groups after training were improved that compared with before training, but as to each magnitude, the experimental group is better than the control group.The results show that:driving strength in the daily training process is lack of adequate exercise. The end of the kicking strength training have significant impact on the basic jump capabilities.
