Question

Why the heartbeat becomes faster if we start on the spot jogging??

Answer 1

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

when we jog our feet need blood to run. at that time anaerobic respiration takes place in our body. So blood purification is not well.  As a result our heart pumps faster.
