The broad, integrated process by which the body maintains physiological stability and equilibrium across its major physical components, including the musculoskeletal, cardiovascular, and respiratory systems. This regulation involves dynamic adjustments to internal and external stressors, ensuring functional capacity and resilience. It is a core tenet of adaptive human physiology.
Origin
This term is a conceptual extension of the principle of homeostasis, applying it specifically to the structural and functional output of the body’s physical machinery. It draws from exercise science, rehabilitation, and clinical physiology, emphasizing the body’s capacity for self-correction and adaptation. The underlying science is rooted in neuro-muscular control and biomechanical efficiency.
Mechanism
Regulation is achieved through continuous feedback loops involving proprioceptors, the central nervous system, and effector organs like skeletal muscle and the heart. For example, maintaining optimal posture requires constant, sub-conscious muscular adjustments governed by the nervous system. Effective physical regulation reduces allostatic load, which is the cumulative wear and tear on the body’s systems, thereby preserving hormonal reserve and promoting longevity.
