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.

  • How does exercise affect the lungs?

    Q: How does exercise affect the lungs?

    A: Although exercise has no effect on lung capacity, exercise benefits the body's cardio-respiratory efficiency, according to Scientific American. During exercise, the heart pumps harder and faster, working with the lungs to deliver oxygenated blood to the muscles. Breathing rate and depth increase as the lungs work to provide more oxygen to the blood pumping through. Exercisers' bodies grow better at loading, transporting and using oxygen.
