Effect of 3% CO2 inhalation on respiratory exchange ratio and cardiac output during constant work-rate exercise.

CONCLUSIONS: 3% CO2 inhalation induced the decrease in RER during CWE at light and heavy intensities, which was due to the decrease in VCO2. The promoted ventilation with 3% CO2 did not lead to the increase in VO2. Moreover, 3% CO2 inhalation did not affect Q during CWE at light and heavy intensities.
