Muscles Talking to Your Organs: Exercise Makes Your Body Chatty (With Myokines)

This review discusses how muscles release proteins called myokines during exercise, which act as messengers to other parts of the body like the brain, fat, and bones, affecting various processes like metabolism, cognition, and even tumor growth. While the exact function of many identified myokines remains unknown, the paper highlights their potential as biomarkers for exercise prescription and therapeutic targets. Much of the research is based on animal models, so more research is needed to confirm these effects in humans.

Possible Conflicts of Interest

None identified

Identified Weaknesses

Preclinical Studies

Many of the studies cited are performed in animal models like mice or rats. This makes it difficult to determine whether or how the findings apply to humans.

Limited Functional Understanding

Although hundreds of myokines have been identified, the paper acknowledges that the specific function of most of them is still unknown, limiting the clinical applications of this knowledge.

Lack of discussion of negative effects

The paper primarily focuses on the positive effects of myokines, but does not delve deeply into the potential negative impacts or downsides, providing an incomplete picture.

Rating Explanation

This review paper provides a comprehensive overview of the emerging field of myokines and their roles in inter-organ communication. It synthesizes a large body of research and presents a compelling narrative for the importance of exercise in overall health. Although many of the cited studies are preclinical, which limits direct translation to human applications, the paper serves as a valuable resource for researchers and clinicians. The lack of in-depth discussion about potential negative effects slightly lowers the rating.
