A University of Bristol study found that aerobic exercise reshapes the stellate ganglia — the nerve clusters that help control heart rate — very differently on the left and right sides of the body, challenging the idea that exercise affects the nervous system symmetrically.
A person's normal resting heart rate is fairly consistent over time, but may vary from others' by up to 70 beats per minute, according to analysis of the largest dataset of daily resting heart rate ever collected. Giorgio Quer of... Continue Reading →
