Previous research in animals shows that caloric restriction reduces resting heart rate and blood pressure, improving cardiovascular health. Aerobic exercise training also reduces resting heart rate and blood pressure, while increasing heart rate variability, a measure of variation in time between heart beats. Higher heart rate variability indicates adaptation to stress (i.e, exercise training) by the parasympathetic nervous system. Over time, exercise enhances the parasympathetic nerves that innervate the heart, slowing heart rate, and improving health. In this clip, Dr. Mark Mattson explains the importance of stressing the cardiovascular system with behaviors such as exercise and fasting to maximize health.
