Anabolic Signaling Window

Meaning

The clinical period post-exercise characterized by heightened sensitivity of muscle tissue to anabolic stimuli, primarily driven by insulin and growth factor signaling cascades. This window represents an optimal time to supply nutrients to maximize muscle protein synthesis (MPS) and attenuate catabolism. From an endocrinology perspective, it reflects a transient shift in substrate utilization and hormonal responsiveness necessary for tissue repair and hypertrophy.
