Information about children's daily physical activity in Eastern-Europe is essential because of the increasing prevalence in overweight and obesity. Sixty-three children (age=11.16 ± 1.10 years; 33 boys and 30 girls) from two public elementary schools had their physical activity objectively measured using uni-axial accelerometer every 5 seconds for five consecutive days (3 weekdays, 2 weekend days). After data cleaning, 10 children were excluded from database. There were no significant differences in boys' and girls' BMI (17.6 ± 2.2 vs. 17.1 ± 2.4) and BF% (18.0 ± 5.2 vs. 19.4 ± 5.0). Children engaged in more sedentary, light, moderate, and vigorous physical activity and had higher counts per minute during weekdays compared to weekend days. There were no sex differences in moderate to vigorous physical activity (87.6 ± 22.4 vs. 93.5 ± 20.6 min and 53.6 ± 21.3 vs. 59.4 ± 22.0 min) during weekday and weekend days. Data indicated that 96% of the girls and 92% of the boys met the international physical activity guideline for children of 60 minutes of MVPA, on weekdays.
由于超重和肥胖的患病率不断上升，东欧儿童日常身体活动的信息至关重要。来自两所公立小学的63名儿童（年龄=11.16±1.10岁；33名男孩和30名女孩）使用单轴加速度计连续五天（3个工作日、2个周末日）每5秒客观测量一次身体活动。数据清理后，10名儿童被排除在数据库之外。男孩和女孩的BMI（17.6±2.2 vs.17.1±2.4）和体脂百分比（18.0±5.2 vs.19.4±5.0）没有显著差异。与周末相比，儿童在工作日进行更多的久坐、轻度、中度和剧烈身体活动，且每分钟计数更高。在工作日和周末，中度至剧烈身体活动没有性别差异（分别为87.6±22.4 vs.93.5±20.6分钟和53.6±21.3 vs.59.4±22.0分钟）。数据表明，在工作日，96%的女孩和92%的男孩达到了儿童60分钟中等至剧烈身体活动的国际身体活动指南标准。
