Respiratory gas measures assessed during fixed submaximal (~ 70%VO_2max) exercise (RUN 1). A Oxygen Consumption (VO₂); B Carbon Dioxide Production (V̇CO₂); C Respiratory Exchange Ratio (RER); D Respiratory Rate (RR); E Tidal Volume (V_T) and F Minute Ventilation (V_E). Breath-by-breath registrations of respiratory gases were collected at three intervals (24–32 (24_EX), 37–45 (37_EX) and 50–58 (50_EX) minutes) during RUN 1. These measures were averaged across each 8-min collection period prior to analysis. Values are mean ± SEM for placebo (white squares) and CBD (green circles) (n = 9)
