During the past fifty years physical education has emphasized such objectives as strength, health, recreation and education. Emphasis in physical education has been influenced by educational, economic and political conditions. As a result of these influences, the physical education programs have gone through various stages of development and change. During certain periods we have had calisthenics, dance, sports, games, and various combinations of these activities. During the past few years, leaders in the field have endeavored to effect a program of study in physical education to be used as a guide for teachers in that profession.
