SEMG Analysis On Technical Movements Of Men Teenager Discus Thrower Of Beijing

Discus track and field sports movement is the rotation of the highly technical sport, it contains many technical aspects, technical movements on the athletes often do not improve, resulting in poor performance. In addition to the athlete's own physical, level of training, technical improvements are also very important. Discus the project due to the movement characteristics for the measurement and analysis of a certain degree of difficulty, in order to find out the reasons for its action imperfect, we have to muscle force by the order of the size and duration of force and other aspects of research and analysis to enable the athletes to improve performance play a role.Objectie:There is a certain degree of difficulty to measure and analyse due to the movement characteristics of discus. We conducted research and analysis by muscle exertion sequence, effort size and duration for finding the causes of action which is not perfect, so as to improve performance of athletes.In the discus exercise training process, which muscular exertion when the discus thrower do the movements? The size and the sequence? Which training methods used more effectively targeted development of these major muscle force? These issues are pressing concerns of the majority of coaches, and both need to understand and grasp.Methods:the study on 10 Beijing youth male athletes are secondary discus throw discus action on the six decomposition action muscle test data and the data, statistical analysis and experiment results.Results:Using remote sensing muscle testing discus action process radiometer is very feasible, and it can be clearly tells us something in the textbook, experience and video equipment which can see on the inner technology. From the test, gastrocnemius and the quadriceps muscle force in the process, but when the very big biceps and triceps lasts for a long time for the high demand for power endurance.
