In the present study, after a total of 51 observations of a 30-min cycle exercise performed by 17 men ranging in age from 60 to 65 years, the following formula was finally obtained for evaluating total O2 uptake (TVO2) during exercise: TVO2 (ml.kg-1) = SR125 X (49.5 X mean HR + 3760) X THB X 10(-4), where mean HR and THB are mean heart rate (beats.min-1) and total heart beats in exercise, respectively, and SR125 is the slope of the regression line of accumulative O2 uptake on accumulative heart beats during exercise at a mean HR of 125 beats.min-1. SR125 was significantly correlated not only to predicted VO2max but also score (X) in the step test for 2 min (25 steps.min-1 on 35-cm stool), yielding a formula, SR125 = -0.00131X + 0.3660. Consequently, both formulae indicate that total O2 uptake of any exercising elderly man can be estimated from total heart beats and mean HR during exercise, regardless of intensity of exercise when SR125 was determined by the step test. The discrepancy between total O2 uptake evaluated by the estimation method for elderly men and that determined by the Douglas bag method was 10.2 +/- 7.3%. |
