As a result, our heart rate must increase to compensate for the reduction in stroke volume, leading to aphenomenon known as cardiovascular drift. The decrease in blood plasma results in a decrease in venous return, the volume of blood returning to the heart, and therefore a decrease in stroke volume, the volume of blood ejected from the left ventricle per beat. These figures will increase further if exercising intensely, particularly during endurance-based exercise or when exercising in warm temperatures. This results in a decrease in blood plasma (the fluid part of blood) and a subsequent thickening of blood.
