Seng Analvsis Of Major Force Muscles On Rotary Stage Of Male Discus Thrower

Research purpose: This paper aims to explore the full monitoring and electromyographicanalysis of the major muscle groups of the surface EMG of the rotating stage in the process ofdiscus throwers throwing to the adoption of mathematical statistics, logical reasoning and surfaceEMG analysis of the data can be effectively determine the differences of the muscles of athletesand action to help coaches understand the athletes should be noted that the technical training andfocus. To build the men’s discus thrower rotating stage surface EMG model, to provide atheoretical basis for future research. And find out the advantages and disadvantages of thetechnology and understanding to grasp the characteristics of the contemporary world young men’sdiscus and technological development, China’s men’s discus throwers to get some reference topromote their sports techniques to optimize and further enhance China’s men’s discus movement.Methods: produced in Finland MuscleTesierME6000portable8guide EMG EMG datacollection of nine elite athletes in the scene complete discus throwing, the use of Megawin EMGanalysis software to analyze the data collected finishing.Research content: surface electromyography of the rotating stage of the discus thrower map;muscle EMG activity start time, end time, duration; average rms amplitude of the muscle EMGactivity; muscle myoelectric activity of integral value; contribution rate of the measured muscle inthe action stage.Results:1. The left foot support rotation and flight phase, the EMG analysis showed that thewrist flexors, trapezius muscle, before the tibialis first involved in muscle force, musclemyoelectric activity in the beginning sequence has: wrist flexorsâ†'The tibialisâ†'trapeziusâ†'thebicepsâ†'quadricepsâ†'erector spinaeâ†'deltoidâ†'biceps femoris; Deltoid, biceps the end of thefirst discharge, the end of the muscle myoelectric activity in order to have: Deltoidâ†'bicepsâ†'wrist flexorsâ†'trapezius=erector spinae muscleâ†'quadriceps biceps femoris=former tibialmuscle; Wrist flexors, trapezius, the longest of the tibialis muscle discharge, the length of thesequence of muscle myoelectric activity duration as follows: Wrist flexorsâ†'the tibialisâ†'thetrapeziusâ†'quadricepsâ†'erector spinaeâ†'biceps femorisâ†'bicepsâ†'deltoid. Rotation of theleft foot support and contribution rate of the flight phase muscles: deltoid, trapezius, erector spinae,followed by the biceps femoris, wrist flexors, the former tibial muscle, the smallest biceps,stockquadriceps.2. The rotation phase of the transition part of the EMG analysis showed that the wrist flexors,biceps femoris, trapezius, the former tibial muscle, erector spinae, quadriceps was first involved inmuscle force and muscle EMG activity began the sequence has to: Wrist flexorsâ†'biceps femorisâ†'the trapeziusâ†'erector spinaeâ†'the tibialisâ†'quadricepsâ†'deltoidâ†'biceps. Deltoid, quadricepslast end of the discharge, the end of the muscle myoelectric activity in order to have: The deltoidâ†'the Quadricepsâ†'erector spinaeâ†'tibialisâ†'the bicepsâ†'the trapeziusâ†'wrist flexors=biceps femoris; The length of the wrist flexors, biceps femoris, trapezius muscle, the tibialismuscle discharge duration of the longest muscle myoelectric activity in continuous time of order:biceps=the wrist flexorsâ†'trapeziusâ†'tibialisâ†'erector spinaeâ†'biceps=quadricepsâ†'deltoid. The contribution rate of the rotating phase of the transition part of the muscles: trapezius,wrist flexors, followed by the biceps femoris, erector spinae, the smallest is the quadriceps, biceps,the former tibial muscle and the deltoid. 3. The entire the discus rotation stage, the former tibial muscle, wrist flexors, trapezius muscle interms of maximum force the longest in the future training should focus on a few muscles of thecomprehensive strength training;quadriceps, the former tibial muscle, erector spinae, trapeziusmuscle contraction speed requirements are high, fast strength training of the few muscles intraining should be strengthened.
