Notes:
P (probability, t-test) < 0.05, females vs males;
P (probability, t-test) < 0.05, “rest vs end” 6MWT;
P (probability, t-test) < 0.05, “measured vs theoretical” 6MWD; data are means for heart rate and 6MWD and medians (1st–3rd quartiles) for others.
Abbreviations: 6MWD, 6-minute walk distance; VAS, visual analog scale; bpm, beats per minute; oxy-sat, oxyhemoglobin saturation.
