在校大学生动静态平衡能力的相关性及影响因素

Study on the Correlation between Dynamic and Static Balance Ability of the Undergraduates and the Influencing Factors

对60名受试者进行静态(闭眼单脚站立、踏木实验)、动态(前庭步、起立行走、原地踏步)平衡能力及身高、体重等身体形态指标进行测试,结合美国Medical Fitness Solutions动态平衡仪测试结果对各平衡能力测试指标进行主成分分析,对受试者的平衡能力指标与形态指标进行pearson分析,对男女组间的平衡能力进行T检验。研究结果显示:选取的6种平衡能力测试方法都能够较好地反映出人体的平衡能力,且部分平衡能力测试方法间可相互替换;身高、体重、体脂率及BMI与平衡能力均呈显著负相关,身高越高、体重越重、体脂率越高、BMI值越大其平衡能力越差;女性受试者维持平衡的能力显著好于男性受试者(P<0.05),而在移动平衡能力方面男女受试者间无显著性差异(P>0.05)。

Static balance ability （closing one＇s eyes and standing on one foot, tread experiment） and dynamic balance ability （vestibular step, standing up to walk, march on the spot） and body shape indexes of height and weight were measured for 60 subjects. Together with the test results of the dynamic balance instrument of Anlerican Medical Fitness Solutions, an analysis of the principal components of the balance ability indicators was made, Pearson analysis was also made for the subjects＇ balance ability indexes and morphological indexes. T test was arranged for the balance ability of the male and female groups. The result reveals that the 6 methods chosen for the measurement of balance ability can better reflect the balance ability of human body and some methods may be replaced each other. Height, weight, body fat rate and BMI are negatively correlated with bal- ance ability. The higher height, the heavier weight, the higher body fat rate and higher BMI value result in poorer balance ability. The balance ability of the female subjects is clearly better than that of the male subjects （P 〉 0.05）. And there is no significant difference between the moving balance ability of the male subjects and that of the female subjects （P〉 0.05）.
