Skeletal muscle is not just passive tissue; it functions as a critical endocrine organ. Myokines—proteins released during muscle

what it claims

Skeletal muscle acts as an active endocrine organ that releases myokines during contraction, which improve glucose regulation, reduce inflammation, and support brain functions.

holds up

This assertion aligns very precisely with the current scientific consensus in physiology.

noli's read

This assertion aligns very precisely with the current scientific consensus in physiology. Research, notably meta-analyses published in journals such as 'Nature Reviews Molecular Cell Biology', confirms that muscle is a major secretory organ communicating with other organs via myokines like interleukin-6 (IL-6). It is established that these molecules play a key role in glucose metabolism and insulin sensitivity, which is validated by numerous clinical studies (RCT). Regarding BDNF (Brain-Derived Neurotrophic Factor), observational and experimental research effectively supports that it is stimulated by muscular activity and contributes to neuronal plasticity. The creator does not fall into exaggeration here, as these mechanisms are pillars of modern research on longevity and metabolism. No part of this claim appears unfounded in light of current knowledge.

What the graded evidence says

Evidence
D

Linked to, not proven to cause.

Effect
myokine signaling from muscle contraction (mechanistic) — mechanistic evidence for paracrine/endocrine roles in fuel oxidation, inflammation, insulin sensitivity and cognition; no established clinical dose-response
Measured on
mechanistic and preclinical/human physiology studies

What’s uncertain

Myokine biology is emerging and largely mechanistic. There's no solid human evidence that a brief fixed amount of muscle contraction produces the anti-inflammatory or longevity outcomes sometimes claimed online.
