Badminton Players Back Footwork And Special Strength Of Lower Limbstraining Movement Characteristics Of Muscle Electromyography Analysis

Objective:with the development of badminton internationalization,the continuous improvement of the scientific sports training and competition rules,this paper studies back footwork and special lower limb strength training in badminton movement characteristic of leg muscle strength as the object,use the DELSYS company produces the TrignotmWirelessSystem electrical instruments and experimental test,combined with the sports biomechanics and anatomy knowledge and badminton back footwork and special strength training behavioral essentials,comprehensive explanation back legs hard the inherent law of footwork,aims to promote the stability and smoothness of the backward step,to find out the reasonable and effective special training has very important significance.Methods:firstly,four kinds of backstroke and four special strength training methods were used to test the muscles of the legs in the muscles of the legs and to obtain the data of electromyography.Secondly,record the experiment and record the interview.Finally,by using the electromyographic analysis system,the analysis of the analysis and the order of the muscle iEMG were obtained by using the three stages of starting,moving,and moving in the back step.Conclusion:1.From the time of the action completion,the four basic backward steps are required to be the longest in the start-up stage,the mobile hitting stage and the reversing stage.2.Step back with special lower limb strength training movement muscle activation sequence comparison and analysis,in the start stage,left the back 2 steps back and full squat lunge to jump around,turn left the back legs,step back-jump and jump crouch muscle activation in the same order;In the mobile phase,right rear pedal turn + way and full squat lunge to jump around,left the back of 2 steps back and in situ jump 180 ° muscle activation in the same order;In reverse phase,right rear pedal turn + way and full squat lunge to jump around,left the back of 2 steps back and in situ jump 180 ° muscle activation in the same order.3.Step back starting phase limb strength characteristics and special strength training of iEMG contrast analysis,the special lower limb strength training,lower limb in step back starting phase action is hard muscle respectively:full squat lunge jump around-the left rectus,left calf,half squat jump-the biceps femoris muscle in his left,full squat lunge jump-right around rectus,in-situ spin 180°,the biceps femoris muscle in his right,the whole squatting going around-right calf;4.Back mobile shot phase limb strength characteristics and the analysis of the special strength training iEMG,special lower limb strength training movement phase in step backward mobile shot phase lower limb muscle forcibly respectively:full squat lunge jump around-left rectus,left and right of the gastrocnemius muscle gastrocnemius,half squat jump-the biceps femoris muscle in his left,half squat jump-right rectus,back spin 180 °,the biceps femoris muscle in his right;5.Step back reverse phase limb strength characteristics and special strength training of iEMG contrast analysis,the special lower limb strength training movement muscle force of lower limb in step backward reverse phase respectively:full squat lunge jump around-left rectus,left calf,right calf;Half squat jump-left femur,right rectus muscle;In situ spin 180 °,the biceps femoris muscle in his right.6.The four commonly used steps of the test,the right posterior field,and the muscle of the main muscle of the left leg,the biceps muscle of the left leg;In the right posterior field,the muscles of the main force in the rotation + parallel step are the left leg gastrocnemius and the right thigh biceps.The muscle of the main force in the back and forth movement of the left posterior field is the left leg gastrocnemius and the biceps femoris.The muscle of the main force in the 2 steps of the left posterior field is the left leg gastrocnemius and the left leg rectus femoris.7.In the four commonly used special lower limb strength training exercises,the muscle of the main force of the lunges is the left leg gastrocnus and the biceps femoris;In situ jump of 180 ° the muscles of the main power of gastrocnemius,biceps femoris muscle in his right leg left leg;The muscle of half squat jump main force is left leg gastrocnemius muscle,right leg biceps muscle;The main force of the lunges is the right thigh muscle and the left leg gastrocnemius muscle.
