Question

Why do athletes breathe faster and deeper than usual after the race

Answer 1

Athletes breathe faster and deeper after a race because their muscles use ATPs for energy requirement during race, and ATP needs oxygen to work, so after race they breathe heavily and deeply to replenish their oxygen levels in their body.

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.
