Recent health guidelines suggest that children should accumulate 60 minutes of physical activity (PA) of moderate to vigorous intensity every day. The purpose of this study was to assess PA on weekdays, in addition to physical fitness, in elementary school children during short-term extracurricular activities (EA). Children from an elementary school (n=160) who carried out EA were assigned to the EA group, and children from the neighboring elementary school (n=210) comprised the non-EA group. A physical fitness test was applied to evaluate physical fitness in pupils. Moreover, 48 children (EA, n=24; non-EA, n=24) wore a pedometer with a uniaxial accelerometer to determine the amount of PA and time spent in moderate- to vigorous-intensity PA. The PA of EA was evaluated with the exception of the short program (10 min). Jogging distance of the EA was 1357 ± 333 m, average speed was 170 ± 42 m/min. The estimated energy consumption of jogging was 55 ± 19 kcal. Multiple items of the physical fitness test scored significantly higher in the EA group than in non-EA subjects. Total step counts were 15485 ± 1915 steps/day for the EA group and 12363 ± 2464 steps/day for the non-EA group on weekdays (p<0.001). Time spent in moderate- to vigorous-intensity PA on weekdays was 61.6 ± 10.0 min/day for EA children and 46.5 ± 12.9 min/day for non-EA children (p<0.001). In addition, the extent of PA in the EA group was higher than the amount recommended for children in general. This study suggested that short-term EA are related to both the fitness and PA levels of elementary school children.
