HM (Hormone in Muscle)
Hormone in Muscle
Short definition
Hormone delivered to the muscle, where it triggers protein synthesis and adaptation.
Full definition
HM is the hormone taken up by muscle tissue from the blood (HB). It acts on receptors to drive myofibril (MF) synthesis and other adaptations; higher HM means a stronger anabolic signal.
Examples
Insulin HM after a carbohydrate meal boosts glycogen synthesis.
