Validity of Submaximal Cycle Ergometry for Estimating Aerobic Capacity

摘要

The accepted method for determining maximal oxygen consumption is collection and analysis of expired gases which has been limited to the research laboratory. Although a variety of tests may be more practical, the relative safety, validity, and reliability has been a concern. To simplify the Wahlund/ Astrand-Rhyming protocols to enhance test precision as well as making it reasonable for the non-technically trained test administrator, a procedure has been developed that allows early selection of the most appropriate test work load. A computerized version makes it possible for non-trained personnel to safely administer this test for estimating aerobic capacity. This study critically evaluates the relationship between estimates of maximal oxygen consumption by a specific cycle ergometer protocol and (1) values obtained by the criterion method employing indirect calorimetry and exhaustive treadmill exercise, and (2) the very high and very low levels of aerobic capacity that are implicit for competitive endurance athletes and for documented sedentary adults, respectively.
