The purpose of this study was to investigate motivational attitudes toward participating in physical activity among international students attending colleges in the United States. Five-hundred twenty-one students participated in this study. The results indicated that the factors of organic development ("keeping good health and physical condition, getting regular exercise, developing and maintaining sound and proper physical functioning") and lifetime uses ("Developing skills for lifetime and learning activities which could be continued out side of school") were valued as the most important motivations to participate in physical activity among participants. Administrators of international students and campus recreation programs should understand the findings of this study to provide better opportunities to international college students for a better quality of life.
