The history of sport psychology began back in the late 19th century, with Norman Triplett. Triplett was a psychology professor at Indiana University during this time, and he conducted research on cyclists. The results of his research showed that the cyclists in his experiments typically performed better when they were riding with others in a group, compared to when they were riding alone. In 1920, the first sport psychology laboratory was founded by Carl Diem in Germany. Coleman Griffith, who worked with athletes from the Chicago Cubs, soon followed suit and founded the first sport psychology laboratory in the United States. It wasn't until 1987, though, that the American Psychological Association created the sport psychology division, Division 47.
Weight gain has been associated with excessive consumption of fats, (added) sugars, refined carbohydrates in general, and alcohol consumption.[citation needed] Depression, stress or boredom may also contribute to weight increase,[citation needed] and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night's sleep lost more than twice as much fat as sleep-deprived dieters.[5][6]
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
