项目摘要

Energy expenditure was analyzed by the doubly-labeled water method in 30 fifth graders living in an agricultural and fishing village (20 males and 10 females). The mean energy expenditure of these children was 2009.8±272.6 kcal/day. Also, the energy expenditure for physical activities (PAEE) was 558.4±206.1 kcal/day, and the physical activity level (PAL = total energy expenditure (TEE)/basal metabolic rate (BMR)) was 1.61±0.18. The intensity of physical activities was measured simultaneously using Lifecorder PLUS (LG: Suzuken), and the intensity of activities at LC0.5 was classified as very mild (inactive period), that at LC1-6 as low to moderate, and that at LC7-9 as high according to the report by Adachi et al. (2007). As a result, the PAL increased with decreases in inactive periods (very mild physical activities) and increases in activities at low-moderate (LC1-6) and high (LC7-9) intensity levels. The PAL was affected by high-intensity physical activities in children, unlike in adults, and further evaluation is necessary. In addition, a significant correlation (r=0.521) was observed between the number of walking steps per day and PAL. According to the regression equation obtained, the number of walling steps corresponding to PAL1.5 is 8,179, and that corresponding to PAL1.6 is 10,957; the PAL increased by 0.1 with an increase of 2,778 steps. There is a report that the number of walking steps in Japanese children was roughly 27,000 about 30 years ago (Hatano, 1979), which corresponds to PAL2.2 according to the regression equation obtained in this study. The results of this study dearly indicate bow inactive Japanese children have become. Concerning the relationships between the results of sports tests and PAEE, significant correlation were observed in all items except flexibility. This year, the physical activity level was measured in 25 children living in cities by the doubly-labeled. water method.

采用双标记水法对生活在农业渔村的 30 名五年级学生（男 20 名，女 10 名）进行了能量消耗分析，这些孩子的平均能量消耗为 2009.8±272.6 kcal/天。体力活动量（PAEE）为558.4±206.1大卡/天，体力活动水平（PAL=总能量消耗（TEE）/基础代谢率） (BMR))为1.61±0.18，同时使用Lifecorder PLUS(LG：Suzuken)测量体力活动强度，LC0.5的活动强度被分类为非常轻度(不活动期)，LC1-6的活动强度被分类为非常轻度(非活动期)。根据 Adachi 等人 (2007) 的报告，PAL 为低至中度，LC7-9 为高。与成人不同，儿童的 PAL 受到高强度体力活动的影响，并且中低强度 (LC1-6) 和高强度 (LC7-9) 的活动增加。另外，每天步行步数与PAL之间存在显着相关性（r=0.521），根据得到的回归方程，PAL1.5对应的爬墙步数为8,179，而PAL1.5对应的爬墙步数为8,179。 PAL1.6为10,957；PAL增加了0.1，增加了2,778步有报告称，大约30年前，日本儿童的步行步数约为27,000步（Hatano，1979），与PAL2.2相对应。根据本研究得出的回归方程，该研究的结果清楚地表明了日本儿童的弓不活动性与结果之间的关系。今年，采用双标水法对25名城市儿童的体力活动水平进行了测量。
