A combination of an increased heart rate and blood viscosity puts greater strain on the heart, resulting in our heart working harder at a given intensity, potentially resulting in early fatigue. Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress. Cardiovascular Drift. The cookie is used to store the user consent for the cookies in the category "Performance".
