The Effect Of Upper Limbs Explosive Force Training Of Tennis Enthusiasts On The Serve Speed

Background: Sports into people’s life, the tennis sport for the public’s favorite, but also cause everyone’s attention to tennis. In tennis, if the players want to get the opportunity to take the initiative to seize the opportunity to seize the opportunity to serve. At present, judge a tennis player’s technology is only from its service technology can decide, in short, the service is not only the important standard of tennis technology, or the best shortcut to score. Tennis technology in our country and the promotion of tennis relative to the rest of the world is still relatively backward, in tennis serve technique research in our country is still not deep enough, in training haven’t found skills, need to continue to other tennis sport development good country to study. In China learn tennis professionals is less and less, even understand also tend to have a smattering of, which makes Tennis Technical Education cycle fracture and educators. And in our country, the research on tennis serve technology based on biomechanics theory and analysis accounted for a large part, on tennis serve by EMG test of explosive force is compared with the less. Moreover, the research is not deep enough.Objective: to tennis enthusiasts were tested electrophysiologically, and then analyzes the data to find the data again to study, purpose is to study muscle explosive force to serve the role, for the tennis teaching to provide the theoretical basis and to serve the training to determine the correct training methods.Methods: The study subjects were Xi’an Institute of Physical Training class tennis 20 students were randomly divided into experimental group(10 people) and control group(10 people) groups. Serve test speed and upper arm EMG. The experimental group received special training muscle control group taking common training. When the length of training for two months, the experimental test interval of one month. Measure: the experimental group and the control group deltoid biceps in angular velocity 60 ° / s, 100 ° / s, 120 ° / s, when IEMG, RMS, AP. Experimental group and control group out of ball speed.Results:(1) the experimental group biceps muscle after two months of special training IEMG value, RMS value, AP values were higher. Especially after the second month of training in the experimental group biceps IEMG value, RMS value, AP values are significantly improved. Group biceps IEMG value, RMS value, AP value no significant improvement.(2) the experimental group deltoid muscle after two months of special training IEMG value, RMS value, AP values were higher. Especially after the second month of training in the experimental group biceps IEMG value, RMS value, AP values are significantly improved. Group deltoid IEMG value, RMS value, AP value no significant improvement.(3) ball speed out of the experimental group sustained rising trend in the three experiments, particularly in the first two months after the training, out of ball speed increase significantly. The control group without special training, although the lift out of ball speed, but to enhance the rate is lower than in the experimental group to enhance the rate of three tennis ball test. Conclusion:(1) the experimental group biceps muscle after two months of training with specific indicators have been enhanced, improved muscle explosive. Feasible and effective training programs.(2) the experimental group deltoid muscle after two months of training with specific indicators have been enhanced, improved muscle explosive. Feasible and effective training programs.(3) in the experimental group after two months of special training ball out of the speed has improved greatly, especially in the first two months after a substantial increase in speed training tee, with the experimental group biceps, deltoid through the second after months of training significantly improved explosive match. Description limb explosive speed and tennis ball out of the association. Tennis ball out of the upper limb speed with increasing explosive power has increased. When the tennis ball teaching and training, targeted exercises and training major muscle force, the use of light equipment for small auxiliary exercises, tennis serve to further strengthen the core muscles of the exercise area, can improve tennis serve stability and threatening.
