German Professor of Medicine and Physiology Otto Meyerhof (1884-1951) discovered the fixed relationship between muscular oxygen uptake and lactic acid metabolism. He showed that the consumption of a molecule of oxygen prevents the formation of two lactate molecules. Meyerhof's findings supported the assumption that lactate enzymes also function aerobically, but that the lactate formed is re-synthesized in carbohydrates at the expense of the energy delivered by the respiration. Because of Nazism, Meyerhof fled to Paris in 1938 and two years later he emigrated to the United States where he was appointed Professor at the University of Pennsylvania in Philadelphia.
Navy officer and gymnast teacher Georges Hebert (1875-1957) played a prominent role in France in the rise of physical education. After studying the principles of his predecessors, he started his own 'natural method', entirely based on natural movements such as walking, running, balancing, jumping, crawling, climbing and manipulative skills such as lifting, throwing and self-defense. Hebert was responsible for the physical training of the sailors of the French navy and in 1913 opened the largest and most modern indoor/outdoor training center in Reims. In 1912 he published a first book L'Education Physique ou l'Entrainement Complet par la Methode Naturelle (Physical Education or total training by the natural method), followed by many other works on the same subject.
