n saturation.; STP Subjective thermal perception.; Ti/TTOT Duty cycle.; VE Minute ventilation.; VCO2 Carbon dioxide output.; VO2 Oxygen uptake.; VT Tidal volume.; VT Ventilatory threshold. HighlightsFacemasks affect the breathing pattern by changing the frequency and amplitude of pulmonary ventilation.The augmented ventilatory work increases VO2, VCO2, and RPE and promotes nonconcerning drops in SpO2 and CO2 retention.Increased inspiratory and expiratory pressure can account for the reduction in pulmonary ph
