Effects Of Long-term Taichi And Walking Training On The Gait Of The Aged People

Objective: With increasing age, People’s organizations and systems have suffereddifferent degrees of decline, particularly the decline in balance, gait abnormalities,leading to a gradual increase in the risk of falls in older People. Caused by falls in olderPeople the social costs are growing year by year, gradually falls in older People becomean issue of common concern to the whole society.Tai chi and vigorous walking exercisecan delay the stability of the recession, to maintain the balance of the old, so that whenthey face to uphills and obstacles, they can walk cross easily. In this study, Viconinfrared motion capture system, Kistler force platform and Zebris treadmill gaitanalysis system were used to test level surface walking gait, ramps gait and crossobstacles gait, which got from long term tai chi and walking exercise old women. Inorder to find out changes of the gaits in the elderly under the conditions of differentwalking, while providing guidance and assistance to the elderly fitness and furtherstudy.Methods: Select the12long-term tai chi exercise older women for tai chi group,12long engaged in walking exercise older women for walking group.All subjects had nowalking function of lower limb disorders, physical healthy, written informed consentprior to testing.First, the static balance test, then the level of road gait, ramps gait,andobstacle crossing gait tests. Use Win-pod Balance tester to measure static balance,Zebris treadmill gait analysis test system to measure the ramp gait, Vicon motioncapture system combines Kistler force plates to measure obstacles cross gait.Independent-samples T test was used to compare two groups of static balance and gaitdifferent levels of walking. Two-factor analysis of variance for exploring the exercisefactors and slopes affecting the gait of the old, exercise factors and the height ofobstacles affecting the gait of the elderly. Results:①static balance：bipedal standing with eyes open state, Xdev. of tai chigroup was significantly lower than walking group (P<0.01)；Under bipedal standingwith eyes closed state，Y speed of walking group was significantly lower than tai chigroup (P<0.05); Standing on one foot with eyes closed state, Avg.v,Y speed and Y devof walking group were significantly lower than tai chi group (P<0.05)；Other indicatorsin the difference between the two groups was no statistically significant(P>0.05).②level ground walking gait: Ant/post position of tai chi group was greaterthan walking group.(P<0.05); Lateral variability of tai chi group was greater thanwalking group (P<0.05). Other indicators of the two groups were not statisticallysignificant (P>0.05).③ramp gait: exercise factors on ant/post position and the momentof left foot’s maximum force,there were significant differences (P<0.05)；Slope factorson the left support phase, single right support phase, there were very significantdifferences (P<0.01);Slope factors for double support phase, ant/post variability, lateralsymmetry,there were significant differences(P<0.05);④obstacles across gait: Exercisefactors on the process of the cross, the ankle joint T1and T2, there were significantdifferences (P<0.01);Exercise factors influence on Fz1、Tz1、LR1、LR2、LR3ofsupporting leg, there were significant differences (P<0.05); Height of obstaclesinfluence on the supporting leg Tz2was significant difference (P<0.05);Exercisefactors influence on swing leg Fz2, Tz3, Fz-min, LR1, LR3,there were significantdifference (P<0.05); Height of obstacles influence on the swing leg Fz-min、LR2weresignificant differences (P<0.05);Conclusions and suggestion:①There are differences in the long-term tai chi andwalking exercise on elderly static balance. Tai Chi group have better left and rightdirection static balance while walking group have better back and forth direction staticbalance.②When walking at normal speed and on level ground,tai chi group showedbetter left and right direction dynamic balance while walking group showed better backand forth direction dynamic balance.③As the slope angle increases, the elderlydiminished capacity to stand on one leg, in order to maintain better physical stability,support older people to take an extended period of time shorter swing to get betterstability. Between different groups, walking group showed better stability anteroposterior direction homeostasis;④Increases with height obstructions, the elderlytake a leap speed slows, reducing cross-paced, so the step size is reduced, theapplication of more time to mobilize the nerves controlling muscle contraction tomaintain body balance and prevent falls occur. Cross different heights obstacle process,tai chi group supporting leg kicking ability is better than walking group off the groundfaster, there is no obvious mopping phenomenon. Kicking and buffering capacity andstability tai chi group were better than in the swing leg walking group.⑤recommendeddiversify as much as possible in the choice of the elderly fitness programs, try todiversify in place when selecting workout.
