It has been suggested that children are less likely than adults to demonstrate a plateau in oxygen uptake (V02) at maximal exercise. However, there has been no direct comparison. Therefore, the purpose of this study was to compare boys and men in achievement of plateau as well as the secondary criteria for maximal effort: heart rate (HR), respiratory exchange ratio (RER), and blood lactate (BLa). Seventeen boys (10.7 ±v 0.6 yrs) and 21 men (22.5 ± 2.0 yrs) completed a practice exercise test and a graded exercise test in order to determine VO2max and achievement of the criteria. The men also completed a second graded exercise test at a faster speed to determine if speed may affect plateau achievement. Comparisons indicated that, except for the BLa criterion, men and boys have similar rates of achievement. In addition, speed does not seem to play a role in criteria achievement. However, due to a small sample size, these results should be viewed with caution. / School of Physical Education
