WebEffect of exercise on heart rate and breathing rate Heart rate and breathing rate increase during exercise to deliver oxygen and remove carbon dioxide faster from respiring tissues. When you exercise, your skeletal muscle is contracting quickly and frequently. This requires energy from respiration. WebParasympathetic nerves can exert their effects more rapidly (<1s) than sympathetic nerves (>5 s). The magnitude of heart rate changes called oscillations, is increased at lower breathing rates (respiratory frequencies) and deeper breaths (higher tidal volumes). So slow deep breathing increases parasympathetic activity and increases HRV.
