This study examined patterns of responses for physiological and perceptual variables during cycle ergometry at a constant rate of perceived exertion (RPE) within the moderate and heavy exercise intensity domains. Nineteen (mean age 21.3 ± 0.5 years; 43.4 ± 2.0 mL·kg⁻¹·min⁻¹ VO_2Peak) moderately trained cyclists performed an incremental test to exhaustion and two 60 min constant RPE rides at the RPE corresponding to the gas exchange threshold (RPE_GET) and 15% above the GET (RPE_GET+15%). Oxygen consumption (VO₂), respiratory exchange ratio (RER), heart rate (HR), minute ventilation (V_E), …
