Living or occuring only in the presence of oxygen, as in certain micro-organisms
Aerobic refers to exercise that requires the presence of oxygen to produce energy. Aerobic exercise includes activities like running, swimming, and cycling.
After exercise your pulse becomes faster. The reason you get exhausted while doing exercise is you can't get enough oxygen into your body.
Your breathing speeds up when you exercise in order to get oxygen to your muscles and heart.
They increase to meet the higher need of oxygen in the body
The lung volume that increases with exercise is vital capacity. When you exercise regularly, your body is more efficient at transporting and using oxygen, making vital capacity marginally bigger and exercise less difficult than someone who is out of shape.
Yes, breathing heavy is the body trying to recover more oxygen. It happens during exercise such as running as your body tries to recover the lost oxygen.
