Explain why an athlete has a high ventilation rate after exercise has finished?
Answers
Answer:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
Answer:
When your muscles, even the heart, are working harder, they are also burning more calories. Your muscles need more oxygen than they normally use to burn these extra calories. Your blood picks up oxygen as it travels through your lungs and delivers it to the muscles you're using. As your level of activity increases, your breathing rate increases to bring more air (oxygen) into your lungs so that your lungs can pump more oxygen into your blood and out to your muscles.
