Question

what is the effect of running on the breathing rate ?​

Answer 1

${\huge {\underline {\purple {\mathbb{ANSWER}}}}}$

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Answer 2

Explanation:

Your muscles require oxygen to work efficiently. Fast, shallow breathing results in diminished oxygen supply to the muscles. Therefore, focus on inhaling for longer periods of time to get as much oxygen to the muscles as possible
