Compare On Characteristics Of Muscle Exertion In The Main Techniques And Special Strength Training Methods Of Tennis

Objective:Through using surface electromyography test on serve and forehand shots and special strength training methods of serve and forehand shots. This study attempts to conclude the muscle electrical signal characteristics of serve and forehand shots as well as the muscle electrical signal characteristics of special strength training methods.Through the relevant analysis, assess the reasonableness of specific strength training, providing the basis theory for the teaching and the training.Method:Make the electronic test on the movement and special strength training method of the serve and forehand shots with the Simultaneous ME-6000 apparatus and Videotaping. Record the electromyography signal and action progress. Do the signal analysis with the matching software of the Electromyography. Data statistics processing uses the T-test and Pearson correlation analysis.Result:(1) During swing ball stage, right refers to the extensor,right anterior deltoid,left external oblique muscle,left gluteus maximus and left rectus femoris are finger muscles. (2)Single-hand side of the cast and solid ball and tee ball swing phase of the right refers to the extensor, the right anterior deltoid integral value and the mobilization rate of significant correlation. Upper and lower extremity strength training and coordination of batting tee swing phase, the front deltoidleft external oblique muscle and the left rectus femoris integral value and the mobilization rate was significantly related. Diagonal ball sit-ups with the ball swing around stage rectus abdominis and external oblique left integral value and the mobilization rate was significantly related. Lower extremity resistance exercise ball with the ball swing phase of the left rectus femoris integral value and the mobilization rate was significantly related. (3)During swing ball stage, right refers to the extensor,right biceps,right anterior deltoid,left external oblique muscle and left gluteus maximus are finger muscles. (4) Sideways before the vote hit the ball with the forehand swing phase of the right brachioradialis muscle, right biceps, right triceps, right anterior deltoid and left integral value and the mobilization of external oblique muscle was significantly related to the situation.Medicine ball forehand swing batting practice and the right stage of the biceps, anterior deltoid and the right integral value and the mobilization of the right pectoralis major significant correlation rate. The left lower extremity resistance exercises and left rectus femoris and gluteus maximus batting swing phase integral value of these muscles and mobilize significant correlation rate.Conclusions:(1)During swing ball stage, refers to the extensor,anterior deltoid,external oblique muscle and gluteus maximus are finger muscles, external oblique muscle is passed up the leg strength necessary to hub. rectus femoris is the driving force of rapid shots. (2)Medicine ball exercises, single-hand side of the cast, the upper and lower extremity strength training coordination, serving lower extremity resistance training, diagonal ball sit-ups found on the lower limb muscle force characteristics, they are better ways of special strength training for serve. (3)During swing ball stage,refers to the extensor,brachioradialis muscle,biceps and anterior deltoid are finger muscles.gluteus maximus and external oblique muscle to exert a more reasonable way,the delivery of leg strength and increase the power of acting on the ball. (4)Sideways before the vote, medicine ball exercises and lower extremity resistance exercises consistent forehand to force model, they are good for forehand special strength training.
