The Effect Of The Improved Version Of Tap Dance On Improving The Ankle-foot Function And Balance Ability Of The Elderly

Purposes:This research will be based on the existing research deficiencies,starting from the mechanics of tap dance,according to the function of the elderly,adaptive improvement in difficulty and rhythm,focusing on the use of tap dance to enhance the muscle strength of the ankle,improve Ankle joint mobility,improve the stability and flexibility of the ankle joint,in order to improve the ankle function of the subject,enhance the body’s balance ability,comprehensively enhance the ability to engage in functional activities,reduce the risk of falls.Method:In this study,50 elderly people who did not participate in any balanced targeted training or ankle-specific training were selected.The subjects were numbered into a computer and randomly divided into 2 groups of 25 people each.Pre-experimental collection:1)basic information(eg gender,age,height,weight,etc.);2)information on healthy lifestyles;3)ankle function test;4)balance ability test;5)functional fitness test.The intervention group performed the tap dance training program three times a week,60 minutes each time,for a total of 12 weeks;22 elderly people in the control group conducted fitness education training,once a month(three times in total),each time for 2 hours,the theme They are"active aging","sports exercise and chronic diseases" and "how to prevent sports injuries".All subjects were tested before and after the experiment,and the experimental data were analyzed to draw conclusions.Results:After 12 weeks of modified tap dance intervention training,the ankle joint strength and the ankle joint flexion angle of the intervention group and the control group were significantly improved,and the increase of the plantar flexion angle of the intervention group was greater than that of the control group.Ankle joint strength in the intervention group:F(2,20)=4.20,p<.05,partial η2=.30,control group ankle joint strength:F(2,20)=1 0.7,p<.05,partial η2=.52;Intervention group:left ankle plantar flexion F(2,20)=41.15,p<.05,partial η2=.80,right planter flexion F(2,20)=41.6,p<.05,partial η2=.81;control Group:left ankle planter flexion F(2,20)=8.56,p<.05,partial η2=.46,right ankle planter flexion F(2,20)=5.20,p<.05,partial η2=.34.In the static balance test,the trajectory of the center of gravity of the intervention group in the standing position of the two feet was reduced with time,F(2,20)=3.56,p<.05,partial η2=.26,and the reduction was higher than There was no significant intra-group change in the control group and the control group,indicating that the ability of the intervention group to maintain the center of gravity was continuously improved.In the functional fitness test,both the intervention group and the control group showed significant improvement in lower limb muscle strength,blink balance,sensitivity,and aerobic endurance.In the intervention group,the lower extremity muscle strength:F(2,20)=3.87,p<.05,partial η2=.28,control group lower extremity muscle strength:F=(2,20)=5.32,p<.05,partialη2=.35 The intervention group had a single-leg balance:F(2,20)=5.37,p<.05,partialη2=.35,control group blinking one-leg balance:F(2,20)=7.18,p<.05,Partialη2=.42;sensitivity of the intervention group:F(1.63,34.2)=21.8,p<.05,partial η2=.51,control group sensitivity:F(1.46,30.6)=8.00,p<.05,partialη2=.28 The intervention group stepped:F(2,20)=4.02,p<.05,partial η2=.29,control group step:F(2,20)=4.63,p<.05,partialη2=.32Conclusion:12-week tap dance intervention training can increase the ankle joint flexion activity,enhance lower limb muscle strength,prolong the time of standing on one leg,improve dynamic sensitivity and aerobic endurance.
