Means and standard deviations of absolute (VO₂Abs) and relative (VO₂rel) oxygen uptake, heart rate (HR), and respiratory exchange ratio (RER) in the three sessions.

	VO2	HR	RPE
VO2Abs (l/min)	2.33 ± 0.27	1.98 ± 0.20 *	2.10 ± 0.29
VO2rel (ml/kg/min)	30.09 ± 3.18	25.49 ± 1.84 *	27.12 ± 3.14 *
HR (beat/min)	137.77 ± 7.32	130.85 ± 6.56	134.71 ± 8.34
RER	1.17 ± 0.32	1.24 ± 0.18	1.22 ± 0.26

* p < 0.05 compared to the control session; VO₂—session in which effort intensity was controlled through VO₂; HR—session in which intensity control was carried out through HR; RPE—session in which intensity control was carried out through OMNI-Cycle.
