  1. Values are presented as the mean and standard deviation, F = Effect size according to Cohen’s two-way repeated-measures ANOVA, η2p = partial eta square, VE = ventilation; RR = respiratory rate, VT = tidal volume, VO2 = oxygen uptake; VCO2 = carbon dioxide output; RPE = rating of perceived exertion. Printed boldly (p <.05) different from the Smith machine (SM) vs. the leg press (LP).
