Comparison of Cardiovascular Responses Between Upright and Recumbent Cycle Ergometers in Healthy Young Volunteers Performing Low-Intensity Exercise: Assessment of Reliability of the Oxygen Uptake Calculated by Using the ACSM Metabolic Equation

Cardiovascular responses should be carefully monitored even during low-intensity exercise using a recumbent cycle ergometer. The V̇o2 estimated using the ACSM metabolic equation did not reflect the actual V̇o2 during low-intensity exercise at 70W or less.
