Researches On The High-level Jump Athlete's Knee Injury In Partial Chinese Sport Universities

Many sports powers take the university as important base for developing sports. Sport University is the future of the overall development trends on the way of sport. The building of high-level sports team in sport universities is an important component of high-level sports team's buildings of all university, even in comparison with ordinary colleges has great advantages on the source, the teacher's strength, training horizontal location equipment and so on. So the sports college is playing lead goat role in the university high-level sports team building. The research of sports college high level athlete's injuries has the very big significance. The knee joint is playing the very vital role in the caper movement; once is injured, has the very tremendous pressure to the athlete physiology and psychology, destruct systematic of sport training characteristic, and affect the training effect. Therefore, to promote healthy development of jump the movement in China, it is necessary to conduct the research to the knee joint injuries, providing certain basis for the scientific training.This paper has mainly utilized synthetic study methods such as the literature material method, the investigation method, the questionnaire survey procedure, and the mathematical method and so on. And it makes investigation of the present situation, the injury characteristic and causes of 158 high-level jumping athlete knee joint injury in Beijing Sport University, Shanghai University of Sport, Wu han Institute of Physical Education, Xi'an Physical Education University, Shenyang Sport University, Tianjin University of Sport, Guangzhou Sport University and Chengdu Sport University. The results are as follows:1 The athletes whose knee joint has been injured account for 98.10%, the uninjured athlete 1.90%. The injured total number is 413, per capita is 2.6 times. It shows that Chinese high-level jumping athlete's knee joint injury is quite common.2 In extent, most are mild and moderate injuries. And in nature injuries are in turn the acute damage, the chronic damage, the acute damage transferring chronic damage.3 In the training lesson the knee joint injury mainly occurs in the special technical training and the quality practice. And the injury also is easy to get in the winter training time and the great physiological load of exercise training before the game.4 In injury type, patella strain injuries account for 25.37%, meniscus injury 20.90%, medial collateral ligament injury 19.40%, knee bursitis 17.16%, cruciate ligament injury 14.18%, lateral collateral ligament injury 2.99%.5 For high jump the medial collateral ligament injury, the patella strain injury and meniscus injury are the main injuries; for long jump the patella strain injury, the knee bursitis and meniscus injury are; for triple jump meniscus injury, patella strain injury and knee bursitis.6 Many reasons would create the jump athlete knee joint injury, like too much exercise, overweight of the partial burden, organism overtired, the unreasonable warming-up exercise, the dispersion attention, etc.7 The preventing measures mainly are strengthening the medical supervision, reasonable arranging of physiological exercise load, completing reasonably the warming-up exercise, and strengthening knee joint's power and flexibility exercises and so on.
