Question

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

Answer 1

while running anaerobic respiration takes place along with aerobic respiration that is why athlete can't breath properly. This is the reason behind an athletes breathing faster than normal after finishing the race

Answer 2

Answer:

Runners need to "breathe faster and deeper" than usual after finishing the race in order to meet the increased demand for oxygen and to expel the excess carbon dioxide released.

Explanation:

• Strenuous physical activities like running, cycling, jogging etc requires more energy by the body.
• Hence, more 'oxygen is necessary' for synthesizing this extra energy and at the same time more carbon dioxide is released due to increased energy production which also needs to be expelled out.
• Hence the brain sends signals to "increase the rate of respiration" to expel the excess carbon dioxide from the blood through the lungs.
