The theory of sports training is an important part of competitive sports, is used to reveal the universal law of sports training, to guide the practice of special sports training, various training activities on the basis of scientific training, and efforts to improve the scientific level of the training. Strength quality is one of the important physical factor determining athletic performance, is an important part of the exercise training. This paper explores the use of surface EMG and kinematics measurement and analysis systems, and other means of cushioning on the Fosbury Flop take-off leg kicking the extensor muscles of the technical aspects of forced full Monitoring and function analysis, analysis of relevant indicators further clear in The take-off in the technical aspects of lower extremity muscle force characteristics provide a theoretical basis for looking for more scientific Fosbury high jump strength training methods. 6 a high jump athlete paper selected for the test object using the the JVC high speed recorders and BIOVISION EMG acquisition system synchronization test buffer Fosbury Flop athletes take-off leg kicking the technical aspects of kinematics and muscle surface EMG study clear the athletes in the take-off process of muscle activation order and acting characteristics. In this study, the following conclusions and recommendations: 1, the Fosbury Flop take off the entire process, the hip knee and ankle in three joint buffer magnitude of the order for the knee, hip, ankle, kicking magnitude in descending order: the magnitude of the ankle, knee, hip, hip angle change curve is relatively flat, ankle angle curve variations; the hip angular acceleration curve is relatively flat, rising ankle angular acceleration. 2, the sequence of muscle activation throughout the take-off process for: biceps femoris tibialis anterior muscle → → gastrocnemius → halibut a muscle → vastus medialis → vastus lateralis → rectus femoris; the end discharge order: tibialis anterior a muscle → the soleus → vastus lateralis muscle → shares medialis → the gastrocnemius → Unit the rectus → Unit biceps; duration from short to long order: tibialis anterior muscle → the soleus → vastus lateralis muscle → shares within The side muscle → the gastrocnemius → the rectus femoris → biceps femoris. 3 of muscles acting percentage of the buffer stage order: biceps femoris, vastus medialis, vastus lateralis muscle, soleus, gastrocnemius, rectus femoris, tibialis anterior muscle; 4, the stage acting kicking percentage size of order: the biceps femoris, vastus lateralis, vastus medialis, gastrocnemius, rectus femoris, soleus, tibialis anterior muscle. 5, kicking stage knee angular acceleration maximum moment, biceps femoris, vastus lateralis muscle, soleus peaks. EMG study, we found that in the entire process of the take-off, soleus, vastus lateralis active muscle contribution smaller contribution tibialis anterior muscle biceps femoris EMG activity continued throughout the the take-off process, the largest percentage of the work is done, so I recommend not only to strengthen the training of future take-off leg kicking active muscles (gastrocnemius, rectus femoris, vastus medialis, vastus lateralis) strength training, also Strength Training to strengthen the muscle groups in the shares, select a more special forces training methods, to improve the effect of strength training, and lay a good foundation for the excellent achievements.
