The problem of the study was to determine if a 3-point estimation procedure for the YMCA cycle ergometer submaximal test (YMOD) provided a more valid predictor of maximal oxygen consumption (VO2 max) than the recommended 2-point estimation YMCA procedure for male and female college students ages 18 to 25 years. Apparently healthy subjects (n = 21 females; n = 25 males) completed the ACSM maximal cycle ergometer test, the YMCA test, and the YMOD test. The reliability estimates of modified YMCA max scores, R = .39, was higher than the reliability estimate from the YMCA, R = -.80. ANOVA results indicated that the means of the VO2 max estimates from the YMOD made by regression equation (YMOD-R) and visually (YMOD-V) were not significantly different, and the Pearson correlation between these variables was r = .99. ANOV As indicated that there was no significant effect of testing order, E.(2, 80) = 0.05, n. > .05, and that the mean VO2 max estimates from the YMCA, the YMOD, and the ACSM tests were not significantly different, E.(2, 80) = 2.97, n. > .05. However, the correlations between the ACSM test and the submaximal tests were very low and not statistically significant (n. > .05). Therefore, the predictions of VO2 max from the YMCA, YMOD-R, and YMOD-V estimates of VO2 max were found to be unsatisfactory.
