Endurance Overtraining Endocrine Impact

Meaning

Endurance Overtraining Endocrine Impact refers to the detrimental hormonal alterations and systemic dysregulation that occur when the volume and intensity of endurance exercise chronically exceed the body’s capacity for recovery. This state, often clinically defined as Overtraining Syndrome, is characterized by a significant disruption of the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes. The resulting endocrine imbalance, including lowered resting testosterone and blunted cortisol response, severely compromises athletic performance, immune function, and overall vitality, signaling a state of profound physiological stress.
