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.

Heart rate is the number of beats per minute. So, cardiac output can be increased by increasing either the stroke volume or the heart rate, or both. --- During exercise, the initial increase in cardiac output is due to an increase in both heart rate and stroke volume.When the level of exercise reaches 40% to 60% of the individual's capacity, stroke volume reaches a maximum. Further increases in cardiac output are largely the result of increases in heart rate.o, cardiac output can be increased by increasing either the stroke volume or the heart rate, or both. --- During exercise, the initial increase in cardiac output is due to an increase in both heart rate and stroke volume.
