Maximum oxygen uptake in healthy nonathletic males
article
Maximum oxygen uptake ( {Mathematical expression} max), maximum heart rate (MHR), blood lactic acid (LA) and pH were measured during bicycle ergometer exercise in 52 men, 22 to 60 years old, engaged in clerical and light manual work (prison personnel and prisoners in the Netherlands). {Mathematical expression} max decreases with, age, but less than expected from previous studies in which the data on young subjects were probably biased in favor of well-trained individuals. The data provide provisional standard values for {Mathematical expression} max in healthy untrained males, derived from a population in which physical activity was similar irrespective of age. MHR and LA decrease significantly with age after elimination of {Mathematical expression} as a variable. In 20 subjects, {Mathematical expression} max was measured with the steady-state method and with a single increasing load test; the differences were small for practical purposes. The increasing load method is useful to estimate aerobic capacity in a single test, even in subjects unaccustomed to exercise tests. © 1966 Springer-Verlag.
