Aging muscles need to blow the carburetor

According to the head of the study, the correct operation of the "carburetor" – the enzyme AMP-protein kinase – is an important factor in slowing down muscle aging. AMPK can be "turned on" with the help of charging and a number of medications that are used to combat type 2 diabetes.
