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.

Best Answer: During exercise, the cells burn oxygen faster to produce more energy for the body, which creates more carbon dioxide as a waste product. This increased carbon dioxide level is detected by the brain, which signals for a higher respiration rate to provide more oxygen for the cells.During exercise, the body's need for oxygen increases dramatically and ventilation rate is increased.The depth of breathing also increases during exercise during exercise due to the anatomical dead space of the respiratory system.The anatomical dead space is the air in the nose, mouth, larynx, tracheas, bronchi and bronchioles.his increased carbon dioxide level is detected by the brain, which signals for a higher respiration rate to provide more oxygen for the cells.
