Question

Why does the rate of heartbeat increase after running? ​

Answer 1

Answer:

When you are exercising, your muscles need extra oxygen some three times as much as resting muscles. This need means that your heart starts pumping faster, which makes for a quicker pulse. Meanwhile, your lungs are also taking in more air, hence the harder breathing.

Answer 2

Answer:

Our heartbeat increases when we do something straneous because our body is requiring a large amount of oxygen, so definitely our body has to work faster and supply the blood in our whole body to meet the needs of the oxygen quickly when compared to the ordniary times.
