The Research On Relation Between The Sports Injury And The Amateur Tennis Player’s Forehand Technology Of Gansu Province

Tennis is a graceful and fashionable sport. It combines body-building,entertainment, relaxation, and appreciation together and is becoming more and morepopular. Tennis is also a sport that needs a lot of intensive actions such as running,sudden stop, turns and vigorous striking etc. which makes all parts of the body underconsiderable pressure. When an amateurish net-man is in court, due to variouslimitations, he is prone to make parapraxis, which is one of the major causes of injuryin sports. If the paraphrases continue for long, the athlete will get injured instead oftrained. So how to improve sports skills to avoid sports injury become a publicfocus. forehand stroke skill is one of the most frequently used skills in tennis, featuredby stretched motions and strong power, which is technically very demanding toathletes. Any mistake or parapraxis can lead to injury. By employing the bio-kineticmechanical approach, this thesis discusses the relation between the regular parapraxisof forehand stroke and sports injuries from the perspective of sports-skill to seek thereal causes.The study is based on amateur’s forehand stroke in Gansu province. Systematicanalysis of the problems in forehand strokeis conducted with three-dimensionalslow-motion technique, and then juxtaposes the results with the injuries of theamateur to seek the causes.1) The injuries of amateurish tennis players in Gansu province are mainly ontheir shoulders, elbows, wrists, kneels, waists and backs. And among them theshoulder, elbow, waist and back are injured liable places, ranking top three onesamong all the injury places of the amateurs.2) Joint damage is mainly due to over-stretching of the arm when striking. Thesuggestions are as follows: firstly, the sequence of extending legs and exertingstrength should be rearranged; secondly, the skill problem of too much decelerationon the right arm at the end of racket driving stage should be amended so that at thisstage, the arm can quickly drive the racket in motion, and assures the striking effectand the correctness of the skill. Thus the optimal stretching angle of the arm at thewaving-and-striking moment can be obtained, and the joint damage on shoulder can be avoided.3) The major cause of elbow injury is that when striking, the athlete hasover-stretched his elbow joints, of which the main reason lies in the actiontiming mechanism of the shoulders, elbows, and wrists. The amateurs shouldmaster the right action timing mechanism to enhance their exercise andpractices and to reduce injuries.4) The injuries of back and waist are mainly caused by over-twist of thebody when driving the racket. First, the twist range of coxa should be widenedtechnically, and the working span of the coxal axis should be lengthened. Whendriving the racket forward, the athlete should exerted strength from coax toshoulder, forming correct lapping action from large body setups to small ones,and reducing the possibilities of only twisting shoulders; secondly, muchattention should be paid to enhancing body-building exercise, especially to thestrengthening of the waist and belly muscles. When muscles become morepowerful, they can stand more pressure and protect the joints. Thus injuries canbe reduced.Due to lacking correct understanding of the technical principle of sports,amateurish tennis players often easily get injured when they are forehand stroke.
