项目摘要

Physical activities were measured using- an accelerometer type calorie counter along with the nutritional intakes, times spent on major activities of daily living, body build, and physical abilities in 1,150 individuals in the 1st-7th and 1 1th grades to set goals of daily physical activity levels necessary at various stages of the development. Data were collected in the years 2000-2001. Although the data are still being analysed closely, some interesting results have already been obtained. They are, for example : (1) The daily number of steps of walking on a weekday was 12,000-14,000 in male pupils and 11,000-12,000 m female pupils in a typical urban elementary school, but it was 18,000-20,000 in male pupils and 17,000-18,000 in female pupils in an elementary school with a wide school district, in which they walked a long distance to school. (2) The daily number of steps of walking was determined by whether the subjects had a gym class on the day of the survey and whether they practiced sports as extracurricular activities as well as by the distance of the school from home. (3) The daily number of steps of walking was markedly small on holidays. (4) Few pupils who walked a large number of steps daily were obese. (5) The daily number of steps of walking was not appreciably related to physical activities (results of sports tests) in elementary school pupils. (6) Concerning the diet, fat and oil accounted for a high percentage, and carbohydrates accounted for a low percentage, of the energy intake, and this tendency was more notable in obese pupils. (7) However, the energy intake was generally balanced with the activity level. (8) The daily number of steps of walking was closely correlated with the activity index (total daily energy consumption/basal metabolism) (r=0.8-0.9) in each grade. From these findings, it is considered to be possible to set goals of activity levels necessary for children at various ages as the number of steps.

使用加速度计型卡路里计数器沿着测量1 - 7年级和11年级的1，150名个体的身体活动以及营养摄入、日常生活的主要活动所花费的时间、身体构建和身体能力，以设定在不同发育阶段所需的每日身体活动水平的目标。数据是在2000-2001年收集的。虽然仍在对数据进行仔细分析，但已经取得了一些令人感兴趣的结果。例如：（1）在典型的城市小学中，男生在工作日的步行步数为12，000 ~ 14，000步，女生为11，000 ~ 12，000步，而在学区较广的小学中，男生为18，000 ~ 20，000步，女生为17，000 ~ 18，000步。他们走很长一段路去上学。(2)每天步行的步数取决于受试者在调查当天是否有体育课，他们是否将体育作为课外活动以及学校离家的距离。(3)假日里，每天步行的步数明显减少。(4)很少有每天走很多步的学生肥胖。(5)小学生每天步行的步数与体育活动（体育测试结果）无关。(6)在膳食方面，脂肪和油在能量摄入中所占比例较高，碳水化合物所占比例较低，这一趋势在肥胖学生中更为显著。(7)然而，能量摄入与活动水平基本平衡。(8)各年级每日步行步数与活动指数（每日总能量消耗/基础代谢）呈显著正相关（r=0.8-0.9）。根据这些发现，可以将不同年龄的儿童所需的活动水平的目标设定为步数。
