Join Marc Hamilton, Ph.D., Professor of Inactivity Physiology, Pennington Biomedical Research Center: Inactivity physiology is a novel way of thinking about the medical consequences of a "sedentary lifestyle." Physical inactivity is not the biological equivalent of too little exercise. In fact, emerging evidence suggests that too much inactivity (primarily sitting) has deleterious effects on health even in people who meet the current exercise guidelines. Dr. Hamilton's work addresses mechanisms underlying the health consequences of physical inactivity, as well as helps raise awareness of the potential insidious dangers of sitting too much.
