Cardiovascular Endurance

Meaning

Cardiovascular endurance is the physiological capacity of the heart, lungs, and circulatory system to supply oxygen and essential nutrients to working skeletal muscles over a sustained period. This measure reflects the efficiency of the aerobic energy system and the resilience of the vascular network under prolonged metabolic demand. Optimizing cardiovascular endurance is a clinical priority, as it directly correlates with reduced all-cause mortality, improved endothelial function, and enhanced hormonal sensitivity. It is a critical biomarker of overall metabolic health and longevity potential.
