Abstract

Background and Aims

Fast and usual-paced 400m 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 400m walks varies based upon age and physical function.

Methods

Participants (26 men, 38 women aged 70–92) completed a fast and usual-paced 400m 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 400m walks were 333.3 and 380.3 seconds, respectively (p<0.0001), and highly correlated (r =.88, P <.001). Higher functioning participants (SPPB >10) had greater differences between tests compared to lower functioning participants (SPPB ≤ 10) (52.9 vs. 26.2 seconds, p=0.005), as did younger participants (age <80) compared to those age 80 and older (56.8 vs. 32.8 seconds, p=0.003).

Discussion

Older and lower functioning participants had greater convergence on the fast and usual-paced 400m walks. Potentially some of these lower functioning and older adults may have already performing 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.
