What is the Origin of Training Timing?

This concept is derived from chronobiology, exercise physiology, and endocrinology, recognizing that the efficacy and physiological impact of exercise are not independent of the time of day. It emphasizes the importance of aligning external stressors with the body's internal hormonal readiness and metabolic capacity.

What is the Mechanism of Training Timing?

For example, scheduling high-intensity training to coincide with the peak in endogenous testosterone and the natural morning rise of cortisol can maximize the anabolic drive and readiness for stress. Conversely, intense evening training can disrupt the necessary pre-sleep drop in cortisol and core body temperature, thereby compromising the Deep Sleep Window and the subsequent nocturnal Growth Hormone release.

Training Timing

Meaning

Training Timing refers to the strategic scheduling of physical exercise and recovery relative to the body’s internal biological rhythms, particularly the circadian rhythm and the hormonal fluctuations of the Hypothalamic-Pituitary-Adrenal (HPA) axis. Optimizing this timing is critical for maximizing anabolic signaling, performance adaptation, and minimizing cortisol-induced catabolism. It is a key factor in maximizing the hormonal response to exercise.
