Exercise intensity where hyperventilation begins relative to CO2 output, a sub-maximal threshold marker.
The respiratory compensation point is identified from gas-exchange data as the intensity at which ventilation rises disproportionately to carbon dioxide production, commonly used as a second ('upper') ventilatory threshold. It is often used to demarcate a severe-intensity training/racing domain and, as in this study, as a predictor of endurance performance.
