This responsibility works tremendously on the emotions of the players. In the dressing room before a critical contest I have seen a “gridiron warrior,” ready in canvas suit, cleated shoes, and leather helmet, sitting grimly on a bench, his fists clenched, his jaws tight, and his face the color of clay. He performed wonderfully when the game began, and after it was over there was a large percentage of sugar in his urine! Probably no sport requires a more sustained and extreme display of neuro-muscular effort than American football. And from the foregoing description of the conditions that surround the contests it is easy to realize that they conspire to arouse in the players excitements which would bring forth very efficiently the bodily reserves for use in the fierce struggle which the game requires. What is true of football is true, though perhaps to a less degree, of the racing sports, as running and rowing. Again great multitudes attend the events, the contests are followed closely from beginning to end, and as the goal is approached the cheering and cries for victory gather in volume and intensity as if arranged for a thrilling climax. The whole setting is most highly favorable to the dramatic development of an acme of excitement as the moment for the last desperate effort to win is put forth. Frenzy and Endurance in Ceremonial and Other Dances Dancing, which formed a significant feature of primitive rituals, has always been accompanied by exciting conditions, and not unusually was an exhibition of remarkable endurance. In the transfer of the Ark to Zion there were processions and sacrifices, and King David “danced before the Lord with all his might.” Mooney[162] in his account of dances among the American Indians tells of a young man who in one of the ceremonials danced three days and nights without food, drink or sleep. In such a terrible ordeal the favoring presence of others, who through group action help to stimulate both the excitement and the activities, must be an important element in prolonging the efforts of the individual. In the history of religious manias[163] there are many instances of large numbers of people becoming frenzied and then showing extraordinary endurance while dancing. In 1374 a mania broke forth in Germany, the Netherlands and France, in which the victims claimed to dance in honor of Saint John. Men and women went about dancing hand in hand, in pairs, or in a circle, on the streets, in the churches, at their homes, or wherever they might be, hour after hour without rest. While dancing they sang, uttered cries, and saw visions. Whole companies of these crazy fanatics went dancing along the public roads and into the cities, until they had to be interfered with.
