Exercise-induced myokines (exerkines) such as SDF1, irisin, and SPARC counteract muscle wasting in diseases like cancer cachexia, COPD, and aging by modulating protein synthesis and degradation pathways.

If you are dealing with muscle loss due to illness or age, regular physical activity is a key treatment. It triggers your muscles to release protective proteins (myokines) that help stop muscle breakdown. You do not need to be an athlete; even moderate aerobic or resistance exercise can help restore these protective factors.

ModerateSupportsMEDIUM confidence
Restoring myokines by physical activity may be added to the list of mechanisms by which exercise exerts preventative or curative effects against a large number of diseases, including the deleterious muscle wasting they may cause.

Why this rating

The paper is a mini-review summarizing various studies, including animal models and some human data, but notes that 'more studies are needed' for many specific myokines.
