Using Electromyographic Analysis The Lower Limb Muscles Working Of Tennis Backhand Hands

With the contintious development of electrical technology mature, most of the electrical technical analysis has been applied to enter the sports project, this article with anatomy movement between the characteristics of technical analysis and advanced science and technology method, is introduced to analyze electromyographic hands to study tennis backhand technolony of lower limb muscle strength characteristics. In this paper, the Mega - 16 (Finland), radar (USA) myoelectricity tester and related equipment,to the hands of the three different stance backhand technique to trace and its significance for further tennis player then he hit a ball at the completion of the hands the action, of muscle power sequence, muscle force and the ratio of maximum contribution,in order to guide tennis player double inverse technique to provide scientific support and provide scientific basis for tennis teaching.The results show that:1, in the open, half open, and the closed three stance, he hit a ball the technical movement in tennis player hands muscle power shots process phaes sequence, there was no significant difference.2, in the open, half open and the closed three stance, tennis player hands muscle action shot he hit a ball the technology process of integral electrical values have significant differences shares muscle (left), glutes (right) the tibialis anterior muscle (left) the (left) and vertical muscle electromyography of integral electrical value is bigger, belongs to the active muscle of shots, more accord with dynamic chain theory in tennis.3, in the open,half open and the closed three stance,the tennis player’s hands he hit a ball the technical movement muscle contribution has significant differences, open stance shot phase vertical muscle (right) biggest contribution rate; Half open shots stage raphe artisan muscle (right) biggest contribution rate; And in the closed stance to hit the ball in larger contribution rate is broadly tensor fascia (left). Hands backhand phase glutes (right) and sartorius (left) contribution rate is low, and the vertical muscle (right), kno tensor fascia (right) the tibialis anterior muscle (left) and the proportion is larger, can reflect the muscles at the complete theyng over stage plays the biggest role. low, and the vertical muscle (right), kuo tensor fascia (right) the tibial is anterior muscle (left) and the proportion is larger, can reflect the muscles at the complete theyng over stage plays the biggest role.
