Is the Exercise Hormone Irisin a Myth?

Irisin informationIrisin is an exercise hormone that converts white fat to brown fat, reducing the risk of obesity and type-2 diabetes. This hormone provides significant details on how physical activity affects the body at biological levels. The Dana-Faber Cancer Institute and the Harvard Medical School together discovered this hormone.

Researchers studied how muscle cells and body fat biochemically correspond with each other. However, the details about how they communicate with each other had been vague until the researchers analyzed the production of PGC1-alpha, generated by the muscle in profusion before and after workout sessions.

Mice fed to produce abundant quantities of PGC1a in their muscles were as diabetes and obesity resistant as people who exercise frequently. The bump in the conveyance of protein Fndc5 caused the rise in PGC1a. The protein PGC1a disintegrated into pieces, releasing a hormone named Irisin. This hormone penetrates the bloodstream. With biochemical signals, this hormone converts the visceral fat to brown fat. White fats cells store fat and brown fat cells burn calories.

Irisin apparently has a profound effect on our metabolism. Participants in an experiment found that they had elevated levels of hormone in their cells after exercising as compared to before. This hormone is present in the cell membrane in dormant form. Exercise disintegrates the protein and transports the exercise hormone message to other cells of the body. Some white cells converted to brown cells and the pancreas generated more insulin.

This exercise hormone improves metabolic rate and has anti-obesity effects. It helps maintain BMI, avoid weight gain and averts chronic diseases, such as type-2 diabetes. It stimulates the growth of neurons during endurance exercises. The elevated levels of the hormone raised the appearance of brain derived neurotrophic factor, which is involved in learning and memory.

Researchers claim that they have just begun to find out about the benefits of this exercise hormone. They are persisting with finding the hormone’s benefits for type-2 diabetes, insulin sensitivity, weight gain, as well as in neuro-generative diseases, such as Alzheimer’s. The discovery of this hormone is not a chance for people to skip exercise and eat unhealthy. Research shows this exercise hormone is stimulated with repeated sessions of exercise and not during short periods of physical activity.

With so much scientific research, there are chances that Irisin is a myth. It has had some complications and controversies surrounding it since the study first began. Some researchers have provided convincing evidence and contradictory statistics that have raised concerns about the presence of this hormone in the human body.
