What is the relationship between exercise and heartbeat?

The oxygen needed by the human body is inhaled by the lungs and brought into the blood, and then transported by the heart to various parts of the body through blood vessels. At the same time, waste products such as carbon dioxide are collected and excreted from the body. The increase in the amount of human exercise requires blood to transport more oxygen, and the increase in heart beating speed can increase the amount of blood transported.

Find a classmate who usually loves to exercise, and compare with him the practice required to return to normal heartbeat after 1 minute of mobilization. Make these data into a table and compare them to see if they can explain the problem.

It takes less time for students who love sports to return to normal heartbeats than those who don't. This shows that regular exercise can make our hearts stronger.
