Question

Why does an athlete breath faster and deeper both during running and after finishing the run?

Answer 1

because during running our body and muscles require a large amount of oxygen so we breathe faster. This process is volentary so we cannot control it by sudden. If we do so then we will die.

Answer 2

Answer:

An athlete needs to supply extra energy to his muscle cells which have worked hard during running. For this, he breathes faster and deeper so that more oxygen is supplied to the cells. This speeds up the breakdown of food and as a result, more energy is released.
