Energy Constraint as a Novel Mechanism Linking Exercise and Health

Herman Pontzer. Physiology (Bethesda). .

Abstract

Humans and other species adapt dynamically to changes in daily physical activity, maintaining total energy expenditure within a narrow range. Chronic exercise thus suppresses other physiological activity, including immunity, reproduction, and stress response. This exercise-induced downregulation improves health at moderate levels of physical activity but can be detrimental at extreme workloads.
