Sustained Physical Endurance

Meaning

Sustained Physical Endurance is the physiological capacity to maintain a moderate to high level of physical exertion over prolonged periods, directly reflecting the efficiency of the body’s aerobic and anaerobic energy systems. This capacity is heavily influenced by optimal mitochondrial function, efficient oxygen utilization, and the steady regulation of blood glucose and lipid fuels, all of which are modulated by key metabolic hormones. High endurance is a hallmark of robust metabolic health and cardiovascular fitness.
