Acute Exercise Response

Meaning

The immediate, transient set of physiological and neuroendocrine adjustments that occur in the human organism during and immediately following a single bout of physical exertion. This acute response represents the body’s rapid homeostatic effort to meet the sudden, increased metabolic and energy demands of the active musculoskeletal system. Key components involve rapid alterations in cardiorespiratory dynamics, shifts in substrate utilization, and a coordinated hormonal cascade. These short-term, reversible changes are fundamentally distinct from the long-term structural adaptations induced by chronic exercise training.
