What is meant by breathing? What happens to the rate of breathing during vigorous exercise and why?

Breathing: Breathing refers to the process of taking outer oxygen-rich air inside and exhaling inner carbon dioxide rich air outside or we can say it is the process of exchange of gases.

The rate of breathing increases during vigorous exercise because during vigorous exercise our body consumes more amounts of energy and our body needs more amount of oxygen and need to remove CO₂. So, in order to fulfill this requirement of the body breathing rate increases during vigorous exercise.
