Abstract: The distinguished British physiologist Archibald Hill won the Nobel Prize in Physiology or Medicine in 1922 for his discovery relating to the production of heat in the muscle. His discovery of recovery heat brought a new understanding of the physiological process of muscle activity, which produced important influences on the biochemical study of muscles and laid a solid foundation for the building of new model of muscle at that time. In this paper, this historical event is reviewed and commented, in honor of Hill’s outstanding scientific work and his immortal contribution.

Key words: Archibald Hill, Nobel Prize in Physiology or Medicine, aerobic recovery heat, muscle, lactic acid
