(A) VO₂ and (B) respiratory exchange ratio (RER) during 90 min of cycling at ∼65% VO_2peak in the hydrated (HYD) and dehydrated (DEH) trials. Values are mean ± SD (n = 9). RER was significantly lower than rest at 40, 60, and 80 min in the HYD trial and at 80 min in the DEH trial (P < 0.05). *Significantly greater than HYD trial (P < 0.05). Arrows (↓) indicate ∼1% and ∼2% BM loss.
