For decades, muscles were primarily viewed as structures responsible for movement, posture, and physical strength. In traditional biology, they were often compared to mechanical motors that simply converted energy into motion. However, modern scientific discoveries have completely transformed this understanding. Researchers now recognize that skeletal muscles function as a highly active endocrine organ capable of influencing nearly every major system in the human body. When muscles contract during physical activity, they release hundreds of signaling molecules known as myokines. These molecules travel through the bloodstream and communicate with organs such as the brain, liver, adipose tissue, bones, heart, and immune…
