This study aims to examine children's physical activity with accelerometer by evaluating daily steps and activity time of walking and running classified by accelerometer's intensity, and to create basic data for standard values of appropriate children's daily activity.
The result showed that the means of daily step counts (steps day) are 10, 000-15, 000. The activity time of walking (recorded as 1-6) is 90-120 minutes/day, and above running (recorded as 7-9) is 15-27 minutes/day. MANOVA analysis of physical activity parameter show significant between boys and girls (walk counts: F=7.27, p<0.01, LC1-6: F=9.37, p<0.01), weekday and weekend (walk counts: F=146.39, p<0.0001, LC1-6: F=107.71, p<0.0001, LC7-9: F=158.23, p<0.0001).
But it did not show significant difference between ages. Overall, it is shown that activity volume and intensity are smaller for girls than for boys, and on holidays than weekdays. The interaction was not significant between every combination.
