Why does an athlete breathe faster and deeper than usual after finishing the race?

उत्तर
- Our bodies require energy for all tasks, which is obtained from the oxidation of food during respiration.
- Intense physical activities, such as running, require more energy to accomplish. As a result, additional oxygen is required to meet the increased energy demand.
- Therefore, an athlete breathes quicker and deeper than usual after finishing the race in order to supply extra oxygen and hence, extra energy to the body.
