Abstract: Objective To investigate the current situation on physical activity of college students in Wuhan，and compare the difference of physical activity between male and female students and between science students and arts students，so as to provide support for the formulation of health promotion strategies，and for the improvement of college students′health level. Methods/b> 1 920 college students from five universities in Wuhan were investigated with IPAQ long，including 1 011 male students，909 female students，983 science students and 937 arts students. Results In terms of physical activity type，the male students were significantly lower than female students on housework，but on the leisure- time physical activity，male students were significantly higher than female students. In terms of physical activity intensity， the male students were significantly higher than female students on medium and high intensity and on total amount. In the level of daily physical activity，the proportion of low- intensity physical activity was about 16. 4% . The weekly sedentary time and sleeping time of college students in Wuhan accounted for 54. 0% of the total time of every day. The average duration of activities was less than 30 minutes every day. The male students were significantly higher than female students on physical activity time. There was no difference between science students and arts students in the above aspects. Conclusion Physical activities of college students in Wuhan are mainly moderate intensity，with less high- intensity activities and a higher proportion of low- intensity activities. Most of female students do not have the habit of daily physical activity. The relevant departments should pay more attention to the physical activity of college students in Wuhan，and emphasize to enhance their awareness of physical activity，gradually develop the habit of lifelong physical education for improvement of physical health.
