This it the reason why the pulse rate and breathing rate rapidly increases during exercise. Pulse rate increases when the blood rapidly gets pumped by the ventricles, causing the arteries to expand. As well as it is an indication that extra food and oxygen are being transferred throughout the body. Breathing rates increase due to the fact that during exercise, the demand for oxygen increases to help support the muscles and burn calories more efficiently. Also, when the intensity of exercise increases, more carbon dioxide is produced. So by having a faster breathing rate, it can help deliver more oxygen to the muscles and allow carbon dioxide to be expired more quickly
