Myostatin acts as a negative regulator of muscle growth, and its inhibition is a therapeutic target for muscle disorders and metabolic diseases.
Myostatin is a hormone that naturally limits how much muscle you can build. While current treatments focus on inhibiting it pharmacologically, natural exercise may modulate these pathways, though the paper highlights pharmacological inhibition as the primary therapeutic avenue for muscle disorders.
ModerateSupportsMEDIUM confidence
Myostatin physiologically functions to limit muscle mass. Inhibition of myostatin functions by genetic manipulations as well as congenital anomalies has been known to induce significant muscle growth.

More from this paper
- Skeletal muscle functions as an endocrine organ by synthesizing and secreting myokines (e.g., IL-6, irisin, BDNF) in response to contraction, which exert beneficial effects on remote organs and systemic metabolism.Moderate
- Exercise-induced secretion of myokines like IL-6 and BDNF mediates anti-inflammatory responses and improves glucose metabolism and fat oxidation.Moderate
