中文摘要:
      目的 对小学生身体活动状况进行客观检测分析.方法 研究对象为北京市海淀区和东城区4所小学的1~5年级学生共379名,测量其身高、体重后,应用运动感应器进行身体活动的测量.结果 379名小学生中重度身体活动时间每日平均值为74.09 min,其满足身体活动推荐值的比例为68.9%.男生中重度身体活动时间(79.46 min)高于女生(66.07 min) (P<0.05),其满足推荐值的比例(78.0%)也高于女生组(55.3%)(P<0.05).不同年龄组间中重度身体活动时间差异无统计学意义(P>0 05).正常组、超重组和肥胖组学生轻度身体活动时间差异有统计学意义(P<0.05),中重度身体活动时间差异无统计学意义(P>0.05).结论 小学生中重度身体活动能够达到推荐值的比例较低,应加强小学生中重度身体活动的时间,保证运动效果,促进身体健康.
英文摘要:
      Objective Using the objective detection devices to explore the physical activity status in order to provide evidence reated to the physical activity intervention program on child obesity in elementary students.Methods Subjects were elementary students from grades 1-5 of 4 schools in Haidian and Dongcheng districts,Beijing.After measuring their height and weight,an motion sensor was applied to measure physical activities in these 379 pupils.Results Time on moderate to vigorous physical activities (MVPA) among pupils was 74.09 min and the ratio of meeting the recommended time of physical activity was 68.9%.The MVPA time in males (79.46 min) was more than that in females (66.07 min) (P<0.05),with the ratio of meeting the recommended physical activity time in males (78.0%) also larger than that in females (55.3%) (P<0.05).There was no significant difference between low age group and high age group (P>0.05),however,there showed significant difference in light physical activity time among the normal group,overweight group and the obese group (P<0.05).However,there was no significant difference found in MVPA time among the three groups (P> 0.05).Conclusion The ratio of meeting the recommend physical activity time was low.MVPA time should be increased to guarantee the athletic effects and to improve the health stutas in the pupils.
