(n = 22)	%Δ [HHb]
	a1	a3	[HHb]BP [mL⋅kg–1⋅min–1]
MFO [mg⋅kg–1⋅min–1]	−0.41§		0.66*

Data are presented as Pearson correlation coefficients (r). a₁ and a₃, slopes of the first and second parts of the curve of the double linear model, respectively; [HHb]_BP, breakpoint of the curve of the double linear model; Δ[HHb], variation in deoxygenated hemo- and myoglobin concentration; MFO, maximal fat oxidation; Fat_max, intensity at which MFO occurs; $\stackrel{.}{V}O{}_{2peak}$, peak oxygen uptake. *Significant correlation (p ≤ 0.05). ^§p = 0.06.
