Why does heart rate and breathing rate increase during exercise. 1. When you exercise your muscles contract more frequently, which means they use more energy. 2.To replace this energy your body needs to do more aerobic respiration, so it needs to take in more oxygen and breathe out more CO2. 3.hy does heart rate and breathing rate increase during exercise. 1. When you exercise your muscles contract more frequently, which means they use more energy. 2.
While exercising, the level of carbon dioxide in the blood increases due to increased cellular respiration by the muscles, and so breathing rate increases. When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid.arbon dioxide is produced by the body from everyday activity. If you increase that activity, your body will produce more carbon dioxide. So you body will increase the breathing rate to blow it off. Source(s): RRT, AE-C, EMT.
