Chronobiology and Fitness

Meaning

Chronobiology and Fitness is the clinical application of circadian and ultradian rhythm principles to the timing of physical activity, recovery, and nutritional intake to maximize physiological adaptation and performance. This integrated approach acknowledges that the body’s hormonal and metabolic responses to exercise fluctuate significantly across the 24-hour cycle. Aligning training schedules with endogenous biological clocks can optimize muscle protein synthesis, energy substrate utilization, and recovery processes. The goal is to leverage the body’s natural rhythms for superior fitness outcomes and long-term hormonal balance.
