Man Shot Athletes’ Main Muscle Mass Surface EMG Analysis During Sliding Stage Of Shot-putting

Objective: In this study, surface EMG technology to test the hard muscles in ShotPutting Technique of Back Gliding to arrive at men Excellent Shot Athletes Who Shotbacksliding process demonstrated by the various muscle systems of biological power,in order to understand the athletes sliding electromyographic characteristics, from anew perspective of athletes technology right or wrong interpretation.Methods: Athletes Complete Back Sliding Shot Putting to8Excellent ShotAthletes Who produced in Finland portable EMG-site testing in this process,acquisition-related EMG data, use EMG analysis software the resulting The analysisof the data collation, to arrive at the main force of the athletes muscle surfaceelectromyography characteristics.Results: Slippery preparation phase. Slippery preparation phase the order of themuscle force has: the right anterior tibialis, right trapezius and right pectoralis major,right deltoid, right biceps, right radial muscle, right rectus muscle, left biceps muscle;2. Slippery preparation phase sequence of the end of the muscle activity has: the righttrapezius, left biceps muscleâ†'right deltoid, right anterior muscle, right radialmuscle, the right femoral straight of muscleâ†'right biceps and right pectoralismajor;3. Slippery preparation phase muscle activity duration sequence in: right radialmuscle, right biceps, right deltoid, right rectus muscle, right front tibia bone muscle,right pectoralis muscle, right trapezius, left femoral biceps. From this result, it can beseen right rectus muscle of relatively short duration;4after the group muscle bicepsmuscle is relatively large, the right radial muscle, right rectus muscle and the righttibia muscle full stretch in the state of motion relax ready for backsliding hair force,so synchronization of muscle discharge is relatively low;5in Slippery phasepreparation stage, the contribution rate of the order right biceps, right radial muscle,followed by the right anterior muscle right deltoid and right trapezius, left bicepsmuscle, the contribution rate is relatively small right femoral rectus, right rectusmuscle.The Shot Putters backsliding stage. Has for the in Slippery phase muscle activityin order: right biceps, right anterior tibialis muscle of the right radial, right deltoid,right rectus muscle, right trapezius and right pectoralis major left biceps muscle;2.the backsliding stage end of the muscle activity sequence: right trapezius has leftbiceps muscle, right deltoid, right anterior tibialis, right radial muscle, right femoralrectus, right brachial biceps, right pectoralis major;3. Slippery stages of muscleactivity duration of the order: the right radial muscle, right biceps, right deltoid and right rectus muscle, right anterior tibialis, right chest muscle, right trapezius, leftfemoral biceps;4at Slippery right deltoid, right pectoralis major, the higher thedegree of synchronization of the right trapezius muscle discharge, right rectus muscle,left femoral two muscle, right anterior tibialis muscle discharge synchronization isrelatively low;5in Slippery phase acceleration stage, right deltoid, right biceps,followed by the right radial muscle, right trapezius, left biceps muscle, right anteriortibial musculo-skeletal muscle, the contribution rate of the relative minimum of theright pectoralis muscle, right rectus muscle.Conclusion:(1)right deltoid, right biceps, right radial muscle in the process ofthe Slippery preparation stage, played a very important role, not only need to playthree muscle strength, but also to the development of three block muscleexplosiveness.(2) in the backsliding ready section, to strengthen the right deltoid, righttrapezius the rapid three muscles of the right anterior tibial muscle strength training, atthe same time to pay attention to the right deltoid, right trapezius, right anteriortibialis, right chest four muscle strength muscle endurance training.(3) the amplitude of the pendulum Slippery technically possible to appropriatelyraise the left leg, Slippery more fully and better improve the speed of sliding.
