The best way to prevent dehydration is by regularly taking on fluid throughout your training or competition. 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.
