Question

why does our heart beat faster after running 100m race

Answer 1

our heart need to pump more blood to supply more oxygen to the body as it needs more energy so the heart beats fast to make more blood

Answer 2

Explanation:

• When we exercise or run then our heartbeat got faster because our body muscle needs more energy to work harder. So when we are running then our heart tries to supply more blood or oxygen to the leg muscle.
• So the cardiac output became high and the heartbeat became very fast to supply proper oxygen and the blood to the muscle.
• When you are racing 100m then you can find your heartbeat became very fast but after sometime when you take rest your heartbeat again will back to normal condition.
