  1. Data are expressed as mean ± standard deviation; *Statistically significant difference in relation to non-involved limb (p < 0.05). V ˙ O 2 : oxygen uptake, V ˙ C O 2 : carbon dioxide production, V ˙ E : minute ventilation, f: breathing frequency, VT: tidal volume, V ˙ E O 2 : ventilatory equivalent for O2, V ˙ EC O 2 : ventilatory equivalent for CO2, PETO2: end-tidal pressure of O2, PETCO2: end-tidal pressure of CO2 and HR: heart rate.
