Objective:Since the study of national pupils’s physical activity is few and study methods are rare.using acceleration sensor techonology, we can accurately and scientifically measure the the daily physical activity status and temporal distribution of elementary students.Along with the relationship of the amount of physical activity and physical shape, and analyse the CLASS-C(Children’s Leis-ure Activities Study Survey-Chinese edition) to identify the psychosocial and environmental correlates of objectively measured physical activity behavior.Results:(1) In this survey, the obese boys are13.5%,girls are4.9%;and the overweight boys are14.3%, girls are16.7%. In boarding school and day school,the obese are7.8%and6.4%,;the overweight are19.6%and14.1%.(2) The average time of boys’ sedentary is547.79min/d. girls’is522.61min/d (p<0.05). The time of moderate and vigorous physical activity is48.00min/d (boy) and40.05min/d (girl).(p<0.05),and it is below the guideline.(3) Both In weekdays and weekend,the MVPA time of boys (49.79min/d,46.18min/d) are outstandingly higher than girls (42.79min/d.37.29min/d),And the MVPA time of girls in weekend are lower than weekdays.(4) The difference between in boarding school and day school in the sedentary time and the MVPA time is remarkable. On weekdays,both the sedentary and MVPA time of boarding school (577.18min/d,55.18min/d) outstandingly higher than day school(533.53min/d.46.38min/d). On the weekend,the MVPA time of boarding school lower than day school (boarding school35.14min/d, day school42.394min/d),and outstandingly lower than in the weekday.(5) Those children who have reached60min/d in both weekday and weekend was7.02%.(6) The moderate and vigorous physical activity time of obese children in weekends are37.68min/d while those of normal children are42.31min/d,(p<0.05).(7) Children’s mvpa was associated with school type in weekdays and activity with family member in weekend.Conclusion:(1)The obesity of boys are outstanding higher than girls,and day school are higher than boarding school.(2)Those subjects have reached9h per day of sedentary, far hgiher than foreign peers.(3) The average MVPA time of boys are outstandingly higher than girls,.In weekends, the MVPA time of girls are lower than weekdays.(4) The difference between in boarding school and day school in the sedentary time and the MVPA time is remarkable.(5) Children’s mvpa was associated with school type in weekdays and activity with family member in weekend.
