Exercise

A:

As soon as a person begins to exercise, the heart begins beating more rapidly in an effort to pump oxygen-containing blood to the muscles. In order to contract, which they must during exercise, muscles require more oxygen than they do when at rest. A person's heart rate continues to increase with more exertion until it reaches its maximum capacity.
