Sports psychology began at the end of the nineteenth century in Europe. Sports and the body were now a more important part of people’s lives. During the 1880s, more sports were a part of the lifestyle of the people. But, the word psychology was not used in connection with the word sport before the late 1890s. In 1899 and 1900, the phrase, psychology of sport, appeared in the titles of two journal articles. The first one was by Balduin Groller. It was published in two parts in 1899, in the journal Die Wage under the title “Zur Psychologie des Sportes” (translated About the Psychology of Sport). This article said that there were parts of psychology that had not been researched at that time, that could be connected to sports and physical activities. Then in May 1900, an essay by the founder of the modern Olympic movement, Pierre de Coubertin, was published. It was titled “Le Psychologie du Sport” (translated The Psychology of Sport).
