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 of AMPK, a master energy sensor known as adenosine monophosphate-activated protein kinase. It is a regulator of energy production in response to the tremendous energetic demands of exercise.
