摘要

This study investigated the hypothesis that an individual's maximal oxygen consumption can be realistically predicted by the maximal time achieved in the Balke or Bruce treadmill protocols. Also, the range of maximal oxygen consumptions that can be expected for healthy individuals of any given age and activity habit was evaluated. The maximal oxygen consumptions achieved by one group of men exercised using the Balke protocol and another group using the Bruce protocol were linearly regressed by a least-squares fit technique on maximal treadmill time and on age with activity status classified. Statistical analysis demonstrated an inadequate relationship for predicting maximal oxygen consumption from maximal treadmill time using both protocols. Also, maximal oxygen consumption poorly correlated with age even though activity status was considered. These findings make the nomogram for predicting an individual's functional aerobic impairment a clinical technique of questionable value. Before the prediction of functional aerobic impairment from exercise duration, age, and activity status becomes an accepted clinical tool, other investigators should validate it. (Author)
