Comparison of constant load exercise intensity for verification of maximal oxygen uptake following a graded exercise test in older adults.

Maximal oxygen uptake (VO max) declines with advancing age and is a predictor of morbidity and mortality risk. The purpose here was to assess the utility of constant load tests performed either above or below peak work rate obtained from a graded exercise test for verification of VO max in older adults. Twenty-two healthy older adults (9M, 13F, 67 ± 6 years, BMI: 26.
