A Comparative Study Of The Effects Of Different Exercise Modes On The Balance Ability Of The Elderly

The purpose of this study: The purpose is to test the static balance ability and dynamic balance ability of the elderly in different sports,compare the difference of the influence of Taijiquan and walking on the dynamic and static balance ability of the elderly,and compare the effect of these two sports on improving the balance ability of the elderly.Through the research and analysis of the results of practice,we can choose a reasonable exercise mode for the elderly to improve the elderly.The balance ability provides reference and theoretical basis.Research methods: This paper uses the methods of literature,questionnaire,measurement and mathematical statistics to study.The static balance ability of the elderly was measured by SENNSO MEDICA plantar pressure distribution tester,and the dynamic balance ability of the elderly was measured by Y balance test.The balance ability of the elderly is related to height,weight,age and sports factors.Sports factors are controllable,while other factors are uncontrollable.In this paper,height and weight are used as covariates to analyze the age-related differences of balance ability of the elderly in different exercise modes,and Post Hot method of covariance analysis is used to analyze the differences of indicators among groups.Significant water level was defined as: P < 0.05 was significant difference,P < 0.01 was very significant difference.all experimental data were processed by SPSS22.0 statistical software package and expressed as mean(+SD).The results were as follows:(1)The static balance ability of the elderly at different age stages: the index of the length of the center of gravity sway trajectory,C and D in group II,a and b in group III,had significant difference(P < 0.05).Elliptical area index,in group II,group I,group a and D,group III,a,b,D,had significant difference(P < 0.05).The trajectory length index of X direction had significant difference in group II when a,b,C,group I when D,group III when b and C(P < 0.05).In Y direction,there were significant differences in group a,b,C,C and D in group II,C and D in group I,and a,b,C and D in group III(P < 0.05).(2)Contrast of static balance ability between different exercise modes for the elderly: group I and group II,except for the long track of center of gravity of middle-aged and old people in a,b and C;elliptical area of middle-aged and old people in b,b and D in a,C and D in a;the long track of middle-aged and old people in b,C and D in X direction in a,C and D in b,except in Y direction in b.The trajectory length was significantly different(P < 0.05).Compared with group I and group III,the trajectory of center of gravity sway in four postures in group a and group b was longer;the elliptical area of middle-aged and old people in group b was longer in group a,C and D;the trajectory of middle-aged and old people in direction b,C and D was longer in group a,C and D;the trajectory of middle-aged and old people in direction b,C was longer in direction Y direction in group b,b and C(P <0.05).Compared with group II and group III,there were significant differences between group a and group b except that the center of gravity sway trajectory was longer in group a,elliptical area in four postures in group a and group b,X-direction trajectory in group a and D,and Y-direction trajectory in group a,b and C(P < 0.05).(3)The comparison of dynamic balance ability of the elderly at different age stages: There were significant differences in the three directions of extension distance and comprehensive value of dynamic balance index of left and right lower limbs in group II(P < 0.05).In group I,there were significant differences in the anterolateral and posterolateral extension distances and comprehensive values,and the posterolateral and posterolateral extension distances and comprehensive values of the right lower limbs(P < 0.05).In group III,there were significant differences in the forward and backward lateral extension distances and comprehensive values of the left lower extremity,and the backward lateral and medial extension distances and comprehensive values of the right lower extremity(P < 0.05).(4)Comparison of the dynamic balance ability of the elderly by different exercise modes: Compared with group I,group II and group III,the sum of the extension distances of the left and right lower limbs in all directions in group I and group III;the extension distances and comprehensive values of the left lower limbs in group II and group III,and the extension distances and comprehensive values of the front and inside of the right lower limbs in group II and group III;there were significant differences(P<0.05).Compared with group I and group II,there were significant differences in the extension distances and comprehensive values of the anterolateral and posterolateral left lower extremities,and the posterolateral and medial extension distances of the right lower extremities(P < 0.05).Conclusion:(1)With the increase of age,the static balance ability of the elderly decreases significantly and the stability becomes worse.Taijiquan and vigorous walking can effectively improve the static balance ability of the elderly,slow down the decline of static balance ability,and the improvement effect of Taijiquan is better than vigorous walking.(2)With the increase of age,the dynamic balance ability of the elderly decreases significantly.Taijiquan and vigorous walking can effectively delay the decline of the dynamic balance ability of the elderly,and the improvement effect of Taijiquan on the dynamic balance ability is better than that of vigorous walking.(3)the static balance indexes of the taijiquan group when standing with one foot open eye on the right foot were significantly better than those of the vigorous walking group,and taijiquan had an obvious effect on enhancing the balance ability of the right foot standing with one foot open eye.
