Exercise Chronobiology

Meaning

Exercise Chronobiology is the scientific study of how the timing of physical activity within the 24-hour circadian cycle influences the physiological, metabolic, and hormonal adaptations to exercise. This discipline recognizes that the body’s response to training, including muscle protein synthesis and glucose uptake, is highly dependent on the time of day due to rhythmic fluctuations in gene expression and hormone release. Optimizing exercise timing based on an individual’s unique chronotype can significantly enhance training efficacy, recovery, and overall metabolic health outcomes. It is a key principle in personalized wellness and performance optimization protocols.
