Exercise as Molecular Medicine: Investigational Insights into the Pharmacodynamics of Physical Activity

Abstract

Exercise is universally acknowledged as a cornerstone of preventive health, yet its clinical value extends well beyond general wellness. Modern research is uncovering that the physiological adaptations to physical activity can mirror, and even exceed, the therapeutic effects of pharmacologic interventions. These effects include systemic anti-inflammatory actions, neuromodulatory activity, and metabolic regulation. Framed through the lens of personalized medicine and investigational pharmacology, exercise emerges as a modifiable, dose-dependent stimulus capable of altering disease trajectory across a range of conditions.

​

This review explores the molecular mechanisms and clinical implications of physical activity as a therapeutic modality. Emphasis is placed on how various exercise modalities exert system-wide biochemical effects, how individual variability influences these outcomes, and what implications this holds for precision medicine.
