The Electromyography Analysis Of The Horizontal Bar Rectangular Overhang On Swing Flexion And Extension

Horizontal bar rectangular overhang on swing flexion and extension is one of the ordinary university sports professional gymnastics foundation course content, for beginners in the common course, it is a difficult, technical strong action, after investigation, the students grasp the action in the success rate is not high, when the time is longer than the other. Found after consulting lots of literature, through the study methods of electric horizontal rectangular overhang on swing flexion and extension of literature is less, needs further research. Combining methods of all, this study tries to test students in horizontal rectangular overhang on swing flexion and extension muscle activity in the process of integral electrical values, coordination and contribution, master the skill movements of the electrical characteristics, and with students often prone to error action of integral electrical values were analyzed, such as to find out the differences between the two, and better guide the student to study movement skills, improve the quality of the horizontal orthogonal overhang on swing flexion and extension and the success rate, in order to improve the success rate of students in the classroom this action and innovation strength training methods, promote the effectiveness of the horizontal bar of the teaching and training.Sports field test method, this article use of Finland ME6000 electrical system, can select 20 high quality to complete the action of students at the completion of action on the horizontal bar rectangular trailer swing flexion and extension muscle emg test when the main power, and understand its characteristics and law of muscle electrical data for mathematical statistics and comparative analysis research, summary law and gives Suggestions for high quality complete difficulty movement. Hope that the paper for scientific research action on the horizontal bar rectangular trailer swing flexion and extension, let students learn the right pressure, specific strength training and practical reference guide students, improve the teaching of science.Study the following conclusions:1. the athletes in the first stage in situ to catch-up phase jump to pole, athletes biceps, triceps, deltoid and pectoralis major muscle is the main power, and the latissimus dorsi, rectus abdominis, and rectus muscle force less, a supplementary role. And typical points appeared in the process of jump leg movement of athletes, the contribution rate of the rectus biggest, followed by triceps, biceps and pectoralis major, deltoid participation work less.2.the second phase athletes right upright by the bar under the vertical position to lift a leg pole and then quickly turn the hip process, the main force of muscle group of deltoid muscle, pectoralis major, abdominal rectus muscle and triceps, rectus muscle and the contribution rate of the latissimus dorsi is balanced. And bow legs, feet higher than both side bar athletes rectus, deltoid, pectoralis major, triceps contribution rate is higher, and the right side of the rectus 4% higher than the left.3. the third stage after the athletes physical pendulum to hip by bar upper rapidly into support in the process, the main force of muscle group of athletes deltoid and biceps, arm and shoulder muscles, and under the strength also relatively balanced; And bended leg typical mistakes in the process of sports athletes action mainly hard muscle group also for arm and shoulder muscles, but there is a big difference between the left and right sides of the muscle4. the fourth stage of the body to support, no obvious reverse arch action of athletes right triceps contribution rate is as high as 32%, the left is only 10%.Suggestions:1. strengthen the functional training Functional training is not in order to increase the volume of a muscle, but stressed that the kinematic chain coordination sequence of movement technology. For action on the horizontal bar rectangular trailer swing flexion and extension, in the first two stages, the whole body is rectangular suspension swinging, upper limb muscles and the shoulder joint is nearly stationary, do the centripetal motion, especially pay attention to every stage of the main work of muscles of coordination, athletes of upper limbs and the trunk on the top of the main force, but also pay attention to the coordination of auxiliary muscles, and prevent the formation of typical wrong action.2. pay attention to strengthen the core practice In addition to the upper limb muscle and upper torso, in the second stage, the contribution rate of the rectus is bigger also, so pay attention to the development of upper body strength at the same time, the core strength training should be strengthened, especially the spine- hip- stability degree of the structure of the pelvis.3.strengthen the auxiliary muscle strength In the whole testing process, although some muscle occupy ratio is bigger, because of the limited test muscle, so can’t fully recognized a certain muscle is an absolute main force. Therefore, in addition to the contribution rate of the larger muscle, distal muscle groups should be strengthened, especially the small muscles of muscle strength, strive to make it in the process of the whole movement remains a higher contribution rate, improve the coordination and balance of the body.
