Data are presented as the mean ± SD. a₁ and a₃, slopes of the first and second parts of the curve of the double linear model, respectively; a₂, change in the slope between the first and the second parts of the curve of the double linear model; b, y-intercept of the first part of the curve of the double linear model; [HHb]_BP, breakpoint of the curve of the double linear model; $\stackrel{.}{V}O{}_{2peak}$, peak oxygen uptake. *Significant difference between groups (p ≤ 0.05).
