背景和目的快节奏和通常节奏的400米步行测试通常分别用于评估身体健康或功能，尽管不知道这些测试的表现如何收敛。本研究的目的是确定是否表现在快节奏和普通节奏的400米走不同的年龄和身体function.Methods参与者（26名男性，38名女性年龄70-92）完成了一个快节奏和普通节奏的400米走。使用短期体能成套测试评估功能（评分范围0-12）。结果400 m竞走完成时间快节奏为333.3s，普通节奏为380.3s（P < 0.0001），两者呈高度相关（r = 0.88，P < 0.001）。较高功能参与者（SPPB > 10）与功能较低的参与者相比，（SPPB a千分之一货币符号10）（52.9对26.2 s，P = 0.005），年轻参与者也是如此（年龄< 80岁）与80岁及以上的人相比（56.8s对32.8s，P = 0.003）。其中一些功能较低的成年人和老年人可能已经在正常步速步行过程中发挥了最大能力，而年轻和功能较高的参与者在被要求时能够走得更快。结论步行测试的选择应考虑人群的年龄和功能能力，以及是否对功能或健康感兴趣。
Background and aims Fast- and usual-paced 400-m walking tests are often used to assess physical fitness or function, respectively, though it is not known how performance converges on these tests. This study aims to determine whether performance on the fast- and usual-paced 400-m walks varies based upon age and physical function.Methods Participants (26 men, 38 women aged 70-92) completed a fast- and usual-paced 400-m walk. The Short Physical Performance Battery was used to assess function (score range 0-12). Body mass index and health history were also assessed.Results Finish times for the fast- and usual-paced 400-m walks were 333.3 and 380.3 s, respectively (P < 0.0001), and highly correlated (r = 0.88, P < 0.001). Higher functioning participants (SPPB > 10) had greater differences between tests compared to lower functioning participants (SPPB a parts per thousand currency sign 10) (52.9 vs. 26.2 s, P = 0.005), as did younger participants (age < 80) compared to those age 80 and older (56.8 vs. 32.8 s, P = 0.003).Discussion Older and lower functioning participants had greater convergence on the fast- and usual-paced 400-m walks. Potentially some of these lower functioning and older adults may have already performed at their maximal capacity during the usual-paced walk, while the younger and higher functioning participants were able to walk substantially faster when asked.Conclusions Choice of walking test should consider the age and functional capacity of the population as well as whether function or fitness is of interest.
