System Remodeling Phases

Meaning

The distinct, sequential stages of physiological adaptation that an organism undergoes in response to a sustained, novel stimulus, such as an intensive training protocol or a major lifestyle change. These phases—typically categorized as alarm, resistance, and exhaustion/supercompensation—describe the body’s non-linear process of breaking down, adapting, and rebuilding its functional capacity to a higher set point. Clinically, understanding these phases is essential for precise protocol periodization and maximizing adaptive outcomes.
