Aerobic Exercise

Meaning

Aerobic Exercise describes physical activity sustained at a moderate intensity where the primary energy substrate is derived from oxidative phosphorylation within the mitochondria. This type of exertion necessitates continuous oxygen uptake to meet the metabolic demands of the working musculature. It is differentiated from anaerobic activity by its reliance on oxygen delivery systems. Such activity is fundamental for improving cardiovascular efficiency and metabolic flexibility.
