Cutoff points of simple, rapid, and low-cost functional tests to reflect functional exercise capacity as assessed by...

The 6-Minute Walk Test (6MWT) is recommended for assessing the functional exercise capacity of the elderly. It was hypothesized that faster functional tests could identify low exercise capacity in this population.

To investigate which simple functional test are associated with the performance in the 6MWT of fully functional adults above 60 years of age and to determine the cutoff points that discriminate the worst functional capacity.

The Sit-to-stand test, usual and maximum gait speed, usual and maximum Timed-up-and-go test and the 6MWT were performed.

A total of 113 elderly people aged 67(64-73) years were analyzed. The ROC curve identified the cutoff point of each functional test, which discriminated the worst exercise capacity. The area under the curve were satisfatory (0.549

Cutoff points of simple functional tests can be used to identify elderly people with low exercise capacity.
