Effortless Aching: Indiana University's Ballet Dancers
Ballet is an art form that requires its performers to appear effortless in their work. But a 1975 study conducted by Dr. James Nicholas reported that ballet was more demanding, physically and mentally, than football or hockey. According to a three-year study of the dancers of the Boston Ballet Company, 60 to 65 percent of injuries dancers sustain each year are caused by "overuse." Ruth Solomon, formerly a professor of modern dance at IU, conducted the study with Dr. Lyle Micheli.
