Correlation Analysis Of The Relationship Between The Ordinary College Students' Ankle Muscle Activity And Dynamic Balance Ability

Purpose of this studyThis study, through testing ordinary college students' ability of dynamic balance andsynchronizing semg collection, as well as training the strength of the ankle muscles, aims atexamining the activities of ankle muscles during balance adjustment, and the contribution ofthe adjustment of muscles strength to the ability of dynamic balance, with the purpose ofunderstanding the relationship and mechanism between the activities and the strength of anklemuscles and the ability of dynamic balance.MethodologyJunior undergraduates from school of physical health science, Wuhan Physical Institutewere chosen as the objects of this study. All the16test objects were male students from asame class. They were randomly and equally divided into two groups to receive two tests andone training, including the test of balance ability which consists of single foot stability limittest (los) and single foot stability test (asl) on biodex balance system. In the meanwhile, thetest of balance ability collects semg signals by using the ME6000T16semg testing system.The test group, after the first test, received a6-weeks training of isokinetic strength on biodexsystem-4isokinetic test machine,2times per week. The control group also received two timesof balance ability tests, but without any intervention during the6-weeks interval.Conclusion:(1)through isokinetic ankle flexion can improve the performance of balance abilitydramatically during the balance ability test.(2)The posterior and midpiece of gastrocnemius muscle, the anterior tibialis muscle,the soleus muscle, and the extensor ankle muscles combine different IEMG and MF whichhave different effects on the comprehensive control ability during the stability limit test, andsignificance on equation;(3) As the degreen growing of stability limit test, the probability of muscles combine ofIEMG and MF between the ability of balance is down, and the rate is less. In this4degreensingle foot stability test, there are stable combination in IEMG and MF.(4)Synchronous myoelectricity tester index IEMG has a positive correlation with the performance results in stability limit test and single foot stability test; while MF has anegative correlation with the performance score especially in the single foot stability test.
