摘　　要：目的:探讨不同阻力训练方式对下肢功能增龄性(55~74岁)变化的影响。方法:84名受试者按年龄分为55~64岁组(FS组)和65~74岁组(SS组);然后分别按照检测次序轮流分入功率训练(PT)和离心阻力训练(ERT)亚组,形成FS-PT、FS-ERT、SS-PT和SS-ERT共4个组别,分别接受8周PT和ERT(每周3次),使用计时“起立-行走”测试、6分钟步行测试和楼梯测试评价阻力训练前后下肢功能的变化。结果:FS阶段和SS阶段的TUGT表现在PT和ERT之后明显提高(P<0.05),而6mWT表现没有明显的变化(P>0.05);FS阶段和SS阶段的SAT表现和SDT表现在PT和ERT之后均明显提高(P<0.05),其中SS阶段的SAT表现和SDT表现在ERT之后的提高幅度更加显著(P<0.01)。结论:PT和ERT可通过提高短距离行走、从椅子上坐立以及上下楼梯等日常活动的能力而改善下肢功能的增龄性变化;ERT对上下楼梯能力的提高作用可随着年龄的增加而表现出更大的优势。Objective:To investigate effects of different resistance training methods on the changes of lower limb function with aging(55~74 years old).Methods:84 subjects were divided into 55~64 year old group(FS group)and 65~74 year old group(SS group).Then,subjects in FS group and SS group were divided into the PT and ERT subgroups according to the detection order and formed 4 groups:FS-PT,FS-ERT,SS-PT and SS-ERT.PT and ERT were implemented in 8 weeks(3 times a week).Timed“up and go”test(TUGT),six minute walk test(6mWT)and stair test(ST)were used to evaluate changes in lower limb function with resistance training.Results:TUGT performance in FS and SS stages was obviously improved after PT and ERT(P<0.05),while there was no significant changes in 6mWT performance(P>0.05).SAT and SDT performance in FS and SS stages were obviously improved after PT and ERT(P<0.05),and SAT performance and SDT performance in the SS stage were improved more significantly after ERT(P<0.01).Conclusion:PT and ERT can improve the age-related changes of lower limb function by improving the ability of short-distance walking,sitting from on a chair and standing a chair,and going up and down stairs.The effect of ERT to improve the ability of going up and down stairs could be increased with aging.
