I quickly skinned the article but in a nutshell it seems like the soleus (the main calf muscle) uses more fat and blood glucose than other muscles which primarily use glycogen. Thus using your calves in this specific way can help burn fat. This kind of makes sense as . It agrees with the theory that humans used persistence hunting to run down game and evolved to be excellent long distance runners. IIRC humans usually have about 2000 to 3000 calories of glycogen in their muscles so being able to rely on fat stores becomes critical for longer distances. https://en.m.wikipedia.org/wiki/Persistence_hunting https://en.m.wikipedia.org/wiki/Persistence_hunting
