Examination of the validity of the American College of Sports Medicine (ACSM) prediction equation to estimate submaximal VO2 during cycle ergometry in cyclists and aerobically-trained non-cyclists.
Abstract This study examines the validity of the ACSM prediction equation for estimating oxygen consumption during submaximal cycling in aerobically trained males. The alternate hypothesis of this study is that the estimated vs. actual VO2 during submaximal cycle ergometry would be similar from 50-200 W. A secondary focus analyzes and compares the accuracy of the equation between two distinct groups of subjects (trained male cyclists vs. aerobically-trained male non-cyclists).

From the Paper "The results of this study suggest that the ACSM cycle ergometry prediction equation is most accurate at moderate workloads (~100-150 W). Furthermore, training status has no effect on the predictive value of the equation. Further studies on the effects of training habitus should be fashioned to include a larger sample with greater distinction in training volume, i.e. cycle ~200 miles/week vs. sedentary. Based on the current sample size, subtle differences are very difficult to observe. However, this study provides a strong basis for the direction of future research in this area."
