Study On The Influence Of Different Degrees Of Unstable Training On Balance Ability Of Students In Optional Sports Dance Course

Research purpose:This paper studies the influence of different degrees of unstable training on students’ balance ability in sports dance option course.The research aims are:(1)To systematically introduce the unstable training into the teaching of sports dance optional courses in ordinary colleges and universities.(2)Experimental intervention was used to verify the different effects of different degrees of unstable training on students’ balance ability.Research methods:This paper based on the options of sports dance course development,unstable training characteristics,subjects basic physical condition,relevant literature reference and expert indicators screening determine the experimental training method and test index,combined with the research needs,subjects’ body height,weight,age before the independent sample T test for Yancheng preschool teachers college 40 male college students,the experiment object into experiment group A(flat group),experiment group B(balance mat),experiment group C(balance plate),the subject for 12 weeks of unstable training.The experiment was divided into two tests,and the obtained experimental indicators were analyzed by repeated measures,and the comparison between groups and within groups was used to analyze the subject exercise indicators.Results:After repeated measurement analysis of variance of the balance ability indexes of group A(flat ground group),B(balanced cushion group)and C(balanced disc group),Three different training methods before and after training against Barcelona(right)[(2,33)=8.717,P=0.001<0.05],Barcelona(left)[(2,33)=21.373,P=0.000<0.05],equilibrium rotation[(2,33)=9.332,P=0.001<0.05],standing with eyes closed[(2,33)=3.737,P=0.034<0.05],straight-line walking with closed eyes[(2,33)=6.739,Differeffect for p=0.004<0.05],And the significant difference between experiment group A and experiment group C,Significant difference between group B and group C between baset(left)and equilibrium rotation indicators;In the special achievements of sports dance after training,Between group C and A(p=0.001<0.05),Group B(p=0.027<0.05),There was no difference between experiment group B and experiment group A(p=0.250>0.05).Research conclusion:Conclusion:(1)the unstable training lasting 12 weeks can improve the static balance ability of students in sports dance option course,among which the training effect of balance plate is better than that of balance pad and flat training,indicating that the worse the stable condition,the more conducive to the improvement of static balance ability.(2)The unstable training for 12 weeks can improve the dynamic balance ability of students in sports dance options,and the training effect of the balance plate is optimal.(3)The unstable training lasting 12 weeks can improve the special performance of students,and there are different intervention methods,showing a trend that the worse the stable conditions,the better the special performance.
