BLACKSBURG, Va., Feb. 25 -- Virginia Polytechnic Institute and State University issued the following news release:

Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this mechanism works.

Scientists working at the Fralin Biomedical Research Institute at VTC focused on a triggering event that leads to the activation AMPK, a master energy sensor, formally known as adenosine monophosphate-activated protein kinase. It is a regulator of energy production in response to the tremendous energetic demands of exercise.

The study, published Feb. 25 in Science Advances, confirmed role of...
