Functional Reserve Maintenance

Meaning

Functional Reserve Maintenance is the deliberate, proactive strategy of preserving and enhancing the maximal capacity of key physiological systems—such as the endocrine, cardiovascular, and immune systems—to withstand and recover from significant stress or injury. This concept moves beyond simply treating disease to focus on maximizing the “buffer” capacity of the body, which is a critical determinant of healthspan and resilience. Successful maintenance ensures that the body retains a substantial operational margin above baseline demands, allowing for robust adaptation to future challenges and promoting longevity.
