In addition, the ST was determined by the ventilation curve (VE-by-intensity) and it was confirmed by means of the CO2 ventilatory equivalent (VE/VCO2) (Carey et al., 2005; Wasserman et al., 1973). The curves were visually analyzed by three independent, blinded, experienced exercise physiologists. The points corresponding to the ST for each method were considered valid when two of the three analysts identified the same value. In the present study the determination of the ST by the ventilatory data is considered the gold-standard method
