目的:探讨24周太极拳锻炼对中老年人静态平衡机能的影响。方法:24周简化太极拳和42式太极拳锻炼(每周锻炼4次,每次60分钟)前后,55～65岁中老年人70名分别在双足睁眼、闭眼,单足睁眼、闭眼状态下,采用WIN-POD平衡功能检测系统测试重心动摇总轨迹长(TL)、外周面积(Area)、前后方向和左右方向的动摇指数,其中,双足状态下测试时间为30s,单足状态下测试时间为10 s。结果:24周太极拳锻炼后,(1)双足测试状态下,男性受试者睁眼TL、Area、X轴动摇速度(X speed)、X轴平均摆幅(X dev.)、Y轴平均摆幅(Y dev.)较实验前显著降低(P<0.05);闭眼TL、Area、重心平均动摇速度(Avg.v)显著低于实验前(P<0.05)。女性睁眼Y轴动摇速度(Y speed)显著低于实验前(P<0.05);(2)单足测试条件下,男性受试者睁眼TL、Avg.v、X speed显著低于实验前(P<0.05,P<0.01)。女性受试者睁眼Area、X dev.、Y dev.显著降低(P<0.05,P<0.01);闭眼单位面积轨迹长(L/A)显著高于实验前(P<0.05)、Y dev.显著低于实验前(P<0.05)。结论:24周太极拳锻炼对中老年人静态平衡机能有积极影响。
Objective: To investigate the effect of 24 weeks Taijiquan exercise on the static balance function of middle-aged and elderly people. Methods: Before and after 24 weeks’ simplified Taijiquan and 42 Taijiquan exercise (4 times a week for 60 minutes each), 70 middle-aged and elderly people aged 55-65 were respectively open eyes, eyes closed and single feet open , Under the condition of eyes closed, using WIN-POD balance function test system to test the center of gravity of the total track length (TL), the outer area (Area), anteroposterior direction and left and right directions of the rocking index, wherein the bipedal state test time is 30s, The test time is 10 s in one-foot condition. Results: After 24 weeks of Taijiquan exercise, (1) under the condition of bipedal examination, the male subjects had eyes open TL, Area, X speed, X axis average swing (X dev.), Y axis The mean swing (Y dev.) Was significantly lower than that before experiment (P <0.05). The TL, Area and average center of gravity (AV) of eyes were significantly lower than those before experiment (P <0.05). Y-axis was significantly lower in female eyes than in pre-experiment (P <0.05); (2) TL, Avg.v and X-speed in open eyes of male subjects were significantly lower than those before experiment (P <0.05, P <0.01). (P <0.05, P <0.01). The L / A of closed eyes area was significantly higher than that before the experiment (P <0.05), and Y dev was significantly lower than that before experiment (P <0.05). Conclusion: Taiji exercise for 24 weeks has a positive effect on the static balance function of middle-aged and elderly people.
