After a few historical notes, the present article is devoted to a remarkable study published by Margaria, Edwards and Dill (1933) that, building on Hill and Meyerhof’s theory of muscular contraction, modified it substantially, thus opening the way to the present view of muscle energetics. This can be considered a revolution in exercise physiology, as Hill himself realised.
