[Purpose] Behavioral restrictions during the corona virus disease 2019 (COVID-19) pandemic may have affected the physical activity levels of college students. We aimed to characterize the body composition and physical activity of college students during these behavioral restrictions. [Participants and Methods] The body composition (height, weight, body mass index, body fat mass, body fat percentage, total body muscle mass, free-fat muscle index [FFMI], and fat mass index [FMI]), physical activity, amount the of walking, amount of daily activity, and the number of steps were measured in 52 university students. [Results] For both male and females, the number of steps taken was lower than the average steps reported by the Ministry of Health, Labour and Welfare. In males, FFMI had a strong positive correlation with physical activity, amount of walking, and the number of steps taken. In females, FFMI had a strong positive correlation with physical activity and the amount of walking, as well as a moderate positive correlation with the amount of daily activity. [Conclusion] Since physical activity and walking of university students during COVID-19 affect FFMI, it is necessary to develop an exercise program that considers behavioral patterns.
