BASICS
Description
- The physiologic response to exercise represents a complex interaction of CNS, biochemical, and physiologic factors ultimately resulting in increased cardiac output (CO) proportional to the increase in metabolic demand.
- Exercise training has been demonstrated to be cardioprotective in healthy individuals (primary prevention), as well as conferring a significant morbidity and mortality benefit in individuals with known cardiovascular disease (secondary prevention).
Epidemiology
The vast majority of individuals are candidates for a moderate-intensity exercise regimen, but only 10–20% of individuals actually adhere to the recommendations advocated by the AHA.
Pathophysiology
- The circulatory response to exercise results in an increase in CO proportional to the metabolic demands of the tissue. These circulatory adaptations ensure that the metabolically active tissue ...
