An Experimental Study On The Influence Of Unstable Training On The Balance Ability Of Primary School Students

Balance ability of human body is an important guarantee for daily actionsand mastering sports skills.Primary school is a sensitive period for developing balance ability.Therefore,it is particularly important to choose effective and reasonable balance exercise methods.Objective:To explore the effects of unstable and stable training methods on the development of primary school students'balance ability.Methods:This study mainly adopts the experimental method,and divides 37 eligible primary school students into experimental group(10 males and 9 females)and control group(9 males and 9 females).We conduct teaching experiments for 12 classes for 4 weeks with 60 minutes each.Among them,the experimental group uses unstable training as intervention,while the control group uses stable training as intervention.At the beginning and end of the experiment,the dynamic and static balance ability of the experimental subjects were tested.Research results:By comparing the changes of various indexes of subjects' body balance ability before and after the experiment,the following results are obtained:(1)After 12 classes of training,the test results of the experimental group subjects after walking on the balance beam were significantly different from those before(P<0.05),while the test results of the control group subjects before and after walking were not significantly different(P>0.05).(2)After 12 classes of training,the test results of the subjects in the experimental group showed extremely significant difference from the pre-test results(P<0.01),while the pre-test and post-test results of the subjects in the control group showed significant difference.(3)After 12 classes of training,the test results of the subjects in the experimental group after closing their eyes on both feet were significantly different from the previous test results(P<0.05),while the subjects in the control group showed wireless differences in the total shake track length,peripheral area and track length per unit area(p>0.05).There was a significant difference between the x-axis average center displacement and the y-axis average center displacement(P<0.05).(4)After 12 classes of training,the test results of subjects in the experimental group showed significant differences(P<0.05)in the total shaking track length,peripheral area,track length per unit area,and y-axis average center displacement between the test results of subjects in the experimental group and those in the former(P<0.01),while the test results of subjects in the control group showed no significant differences(P>0.05).(5)After 12 classes of training,the test results of subjects in the experimental group showed significant differences(P<0.05)in the total shaking track length,peripheral area,track length per unit area,and y-axis average center displacement between the test results of subjects in the experimental group and those in the former(P<0.01),while the test results of subjects in the control group showed no significant differences(P>0.05).Research conclusion:(1)Unstable training has a positive effect on improving pupils' dynamic balance ability and static balance ability,and the static balance ability is more obvious.(2)Unstable training and stable training can both improve the static balance ability in the open state of two feet,and there is no obvious difference between the two.(3)Compared with stable training,unstable training can better improve pupils' static balance ability under the conditions of eyes closed by both feet,eyes opened by one foot and eyes closed by one foot.
