Abstract
Hese respective levels of %V̇O2max for the general population. The current study evaluated this relationship between %HRmax and %V̇O2max in apparently healthy, young adults. Eighty-one men and 81 women between the ages of 18 and 34 engaged in an incremental exercise test to exhaustion. Linear regressions of %HRmax and %V̇O2max were performed on each subject. From these regressions, target values of %HRmax were computed for each individual. Mean percentages of HRmax were 63%, 76%, 89%, and 92% at 40%, 60%, 80%, and 85% of V̇O2max, respectively. At all of these values of %V̇O2max, the values obtained for %HRmax were significantly greater (P < 0.001) than those used by the ACSM. Fitness affected these results, particularly among men. High fit men averaged 2% higher in %HRmax than low fit men at any given value of %V̇O2max. ©1994The American College of Sports Medicine...
