稳性与非稳性太极拳练习对女大学生本体感觉和平衡能力的影响

Influence of stable and unstable Taiji exercise on college girls’ proprioception and balance ability

目的探讨稳性与非稳性太极拳练习对大学女生本体感觉和平衡能力的影响,为学生合理、高效健身提供依据。方法招募某大学非体育院系健康且自愿参加实验的60名女大学生随机均分为非稳组、稳定组与对照组。非稳组作非稳性太极拳练习,稳定组作稳性太极拳练习,对照组不作运动干预,实验共进行15周。实验前后分别测试3组受试者膝关节本体感觉及平衡能力。结果非稳组运动觉指标由(0.53±0.11)变为(0.35±0.10),稳定组由(0.51±0.17)变为(0.43±0.09),实验后非稳组运动觉低于稳定组(P<0.05)。非稳组总平衡得分由(1581±284)变为(922±231),稳定组由(1537±266)变为(1320±319),实验后非稳组总平衡得分低于稳定组(P<0.05);非稳组左右向平衡率由(0.42±0.10)变为(0.29±0.09),稳定组由(0.42±0.12)变为(0.35±0.07),实验后非稳组左右向平衡率低于稳定组(P<0.05)。结论稳性与非稳性太极拳锻炼均能改善大学女生下肢本体感觉和动态平衡能力,且非稳性太极拳优于稳性太极拳。

Objective To explore the influence of stable Taijiquan exercise and unstable Taijiquan exercise on college girls'proprioception and balance ability.Methods 60 college girls were randomly assigned to unstable group,stable group and control group.The unstable group received unstable Taiji practice,the stable group received stability Taiji practice,and the control group received no intervention.The experiment was carried out for 15 weeks.Before and after the experiment,the knee joint proprioception and the balance ability of the three groups were tested.Results The kinaesthesia index of unstable group decreased from(0.53±0.11)to(0.35±0.10)(P<0.01).The kinaesthesia index of stable group decreased from(0.51±0.17)to(0.43±0.09)(P<0.05).After the experiment,the kinaesthesia of unstable group was significantly lower than that of stable group(P<0.05).Balance ability:The total balance score of unstable group decreased from(1581±284)to(922±231)(P<0.01).The total balance score of stable group decreased from(1537±266)to(1320±319)(P<0.05).After the experiment,the total balance score was significantly lower than that of stable group(P<0.01).The left-right rate in the unstable group changed from(0.42±0.10)to(0.29±0.09)(P<0.01).The left-right rate in the stable group changed from(0.42±0.12)to(0.35±0.07)(P<0.05).After the experiment,the leftright rate in the unstable group was significantly lower than that in the stable group(P<0.05).Conclusion Both stable and unstable Taiji exercise can improve the lower body proprioception and dynamic balance ability of college girls.And unstable Taiji is better than the stable.
