After 30 minutes of running, cardiac drift may cause your heart rate to increase so that you have to slow down to maintain that heart rate window of 160-170 bpm. 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. The redistribution of blood is essential to performance during exercise because of the limited volume of blood in the human body, approximately 5 litres.

Cardiac output is the product of stroke volume and heart rate. Generation of GCaMP6s-Expressing Zebrafish to Monitor Spatiotemporal Dynamics of Calcium Signaling Elicited by Heat Stress. The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity. Both physical and mental performance has been shown to deteriorate in states of dehydration.

The slideshow presentation below will support learning. At the start of light submaximal aerobic exercise lasting less than 10 minutes, cardiac output and stroke volume initially increase and both then plateau after only a couple of minutes and are maintained for the remainder of exercise. Cardiac drift can be defined as the upward drift of heart rate over time, coupled with a progressive decline in stroke volume and the continued maintenance of cardiac output. Reduced plasma volume, reduces venous return and stroke volume. The accompanying graph relates to the abundance of ocean life (productivity) in a polar region of the Northern Hemisphere.
