Data are presented as the mean ± standard deviation.

GXT, maximal graded exercise test; ${\dot{\text{V}}\text{O}}_{\text{2}}$, oxygen uptake; ${\dot{\text{V}}\text{O}}_{\text{2}}\max$, maximal oxygen uptake; HR, heart rate; HRmax, maximal heart rate; VT₁, first ventilatory threshold; VT₂, second ventilatory threshold; bpm, beats per minute; N/A, not applicable.
