What improves venous return to the heart during strenuous exercise?
Wiki User
∙ 11y ago
Venous return (VR) is the flow of blood back to the heart. Under steady-state conditions, venous return must equal cardiac output (CO) when averaged over time because the cardiovascular system is essentially a closed loop. Otherwise, blood would accumulate in either the systemic or pulmonary circulations.

The higher your degree of fitness, the faster your heart rate will return to normal. .

What can you infer from the fact that your heart beats faster when you exercise?
You can infer that your (healthy) heart is beating faster to compensate for the extra effort your body is making during physical exercise. Once the exercise is over, the time the heart takes to become relaxed and to return to a normal resting beat is a good indication of the state of the health of your heart.

Why does the body need to decrease heart rate after exercise?
When we exercise CO2 is built up in body at a faster rate than at rest. During exercise our body needs more energy. Our body produces energy through cellular respiration. During cellular respiration we convert sugar and oxygen into CO2 and water. Thus the more we exercise the more cellular respiration and thus more CO2 and thus we breath harder and pump blood faster to meet demands we place on body. After exercise we no longer have as much CO2 built up therefore our bodies can return to slower breathing and heart rate.
