ABOUT THIS SESSION

Q&A

The session focuses on skeletal muscles as an endocrine organ and explains how muscles produce hormones that influence overall health.

Muscles are considered an endocrine organ because they release hormones called myokines during muscle contraction, which act on different organs in the body.

Myokines are hormones secreted by muscles when they contract. They help regulate metabolism, brain function, blood vessels, and inflammation.

Exercise causes muscle contraction, which increases the release of myokines, leading to better metabolic health and reduced inflammation.

Important myokines include Irisin, BDNF (Brain-Derived Neurotrophic Factor), VEGF, and Interleukin-6 (IL-6).

Muscle-derived IL-6 has anti-inflammatory effects, unlike IL-6 from immune cells, which can be harmful.

Myokines improve insulin sensitivity in the brain, support nerve growth, and enhance mental and cognitive health.

Myokines increase insulin sensitivity, promote fat burning, and help convert unhealthy fat into healthier fat, aiding diabetes and obesity control.

Exercise helps prevent sarcopenia (loss of muscle mass), maintains strength, and ensures continued hormone production from muscles.

The key message is: Use your muscles to save your muscles. Regular and varied physical activity is essential for overall hormonal and metabolic health.
