Cardiovascular physiologists suggest that cardiac drift is connected to an increase in core temperature and body water losses. The bodies oxygen requirements are mainly dependent upon exercise intensity and duration. Before we take a dive into the deep end, lets get started byfirstdefining the key terms related to cardiac drift. Consequently, the increased heart rate reflects an increased relative metabolic intensity during prolonged exercise in the heat when cardiovascular drift occurs, which has implications for exercise prescription.
