Maximum Functional Capacity

Meaning

Maximum Functional Capacity (MFC) is the quantifiable peak performance level an individual can achieve across multiple physiological domains, including cardiovascular endurance, muscular strength, metabolic efficiency, and cognitive processing speed. It represents the highest achievable output of the body’s integrated systems under optimal conditions, serving as a critical benchmark for health and vitality. In clinical practice, MFC is utilized to define the goal state for personalized hormonal and fitness protocols, moving the focus beyond merely ‘healthy’ to ‘optimized’ function.
