Exercise-induced myokines, including IL-6, IL-15, and FSTL1, mediate muscle-bone, muscle-skin, and muscle-vascular crosstalk, promoting bone formation, skin health, and cardiovascular protection.

Regular exercise helps maintain strong bones and healthy skin by triggering your muscles to release factors like IGF-1 and IL-15. These signals support bone formation and skin structure, contributing to overall long-term health and vitality.

Muscle-derived IGF-1 can act on local osteoblasts that express the IGF-1Receptor and thereby promote bone formation... Tarnopolsky and colleagues demonstrated that endurance exercise improves age-associated skin changes... The study supports the idea that exercise retards skin aging via a mechanism that involves muscle-derived IL-15... FSTL1 has been shown to possess cardioprotective effects, promoting endothelial cell function and nitric-oxide synthase.

Why this rating

Supported by rodent models and some human observational data, but less direct human intervention evidence compared to metabolic effects.
