The Comparative Study Of Soccer Athlete Lower Limb Coordination Under Two Conditions

Just take a look at a variety of sports, we will find a variety of sports in all the technicalperformance characteristics of the action taken on the basis of the process, on the basis of anytechnical action, the whole of the body changes, regardless of any sport, any sport technologyreflected through changes in body movement. Therefore, the coordination ability of the athlete tolearn, master and apply motion technology has a very important role. The quality of coordinationtactics used by athletes and restricts movement and coordination skills to play a variety of sportsskills has a very important role. At present, domestic and foreign research results alsoconsiderable coordination, but in understanding the concept of coordination Shangye there aresome differences in the evaluation of athletes coordinated research capacity is not the same,there is no clear criteria to evaluate the athlete’s coordination Therefore, we need to assess theathlete’s coordination ability, who did further analysis and research. In this study, the use ofsurface electromyography analysis method to investigate the footballer mainly in training beforeand after the change characteristics of lower limbs muscle coordination footballer quantitativedescription. Training before and after training, the subjects of experimental variables chosenNingbo University football team eight people were stepping exercise test were trained before andafter training, EMG analysis through detailed analysis of the common indicators completefootballer significant changes in lower limb muscle action. Training before and after training, thesubjects of experimental variables chosen Ningbo University football team eight people werestepping exercise test were trained before and after training, EMG analysis through detailedanalysis of the common indicators complete footballer significant changes in lower limb muscleaction. Software MEGAWIN mean power frequency (MPF), the median frequency (MF), theaverage magnitude of the contribution rate and activation sequence analysis in the frequencydomain and time domain values of the difference of the two test phases were statisticallyanalyzed using t-test. The results are:1) whether it is before or after training in the training,athletes completed actions than his right leg high score score, his left leg to complete actions toprove the coordination capacity of athletes to complete the action right lower limb coordinationthan good.2)64%-74%, biceps femoris, tibialis anterior,26%-36%of the contribution rate,gastrocnemius, rectus femoris, biceps femoris. Sports gastrocnemius, rectus femoris morecoordinating role, biceps femoris Upon completion of the course, tibialis anterior muscle plays asecondary role, either left or right leg leg muscles before training than the average magnitude ofthe two leg muscles after training side, the average amplitude.3). Gastrocnemius, rectus femorisMPF values were significantly different (P0.05), right leg gastrocnemius, rectus femoris, easierto achieve fatigue after training.
