Abstract:
Objective To explore the correlation between single-leg standing posture control and ankle plantar flexor muscle stability,so as to provide a new theoretical basis for improving the ability of human posture control.Methods A total of 20 healthy male college students were randomly selected as the experimental subjects.The iBalance tester and training system was used to test the trajectory data of the center of pressure(COP)of the foot standing on one leg.The CON-TREX MJ multi-joint isokinetic test and training system was used to test the moment amplitude data during the contraction of ankle plantar flexor muscles.Univariate repeated measures variance analysis was used to analyze the standard deviation data of ankle plantar flexor moment amplitude between groups.The Pearson correlation coefficient was used to study the correlation.Results The greater the intensity of the muscle stabilization task performed by the ankle plantar flexor muscle,the greater the standard deviation of the moment amplitude.The C90 area was positively correlated with the coefficient of variation(CV)of the 10％maximum voluntary contraction(MVC)moment of ankleplantar flexor muscle(r=0.761,P＜0.05)during single-leg standing without interference.The C90 area was positively correlated with the CV(r=0.632,P＜0.05)of the 30％MVC moment of ankle plantar flexor muscle during single-leg standing.When the proprioception was interfered during single-leg standing,the C90 area was positively correlated with the CV(r=0.583,P＜0.05)of the 20％MVC moment amplitude of ankleplantar flexor muscle.Conclusions With the increasing difficulty of muscle strength stabilization performed by the ankle plantar flexor muscles,muscle stability decreases.There is a positive correlation between ankle plantar flexor strength stability and single-leg standing posture control.Compared with the case without interference,under visual and proprioceptive interference,an additional information input is reduced or disturbed,and it is more difficult to maintain body balance,and the ankle plantar flexor muscle needs a higher muscle stability in the force mode to participate in the posture control of the human body during single-leg standing.
