Study reveals how exercise improves metabolic health

Intensive exercise boosts communication between skeletal muscles and fat tissue, fine-tuning metabolism and improving performance, research in mice and humans suggests. The finding may lead to new treatments for metabolic diseases associated with aging and obesity.

Researchers in Brazil have discovered that aerobic exercise triggers the release of signaling molecules into the bloodstream that free up more energy for use by the muscles.
Previous research has found that aging and obesity impair the production of these signaling molecules, known as microRNAs. This increases the likelihood of metabolic diseases, such as diabetes and dyslipidemia.
