EVALUATION OF THE PYSICAL ACTIVITY LEVEL IN JAPANESE ELDERLY PEOPLE (DOUBLLY-LABELED WATERAND VARIOUS SIMPLIFIED METHODS)

在这个为期2年的项目中，我们旨在评估日本老年人的身体活动水平。采用双标签水（DLW）法测量了不同健康水平和健康状态的老年早期至晚期老年人的总能量消耗，并对各种简化方法的精度和存在的问题进行了评价。测量或调查的项目有：1。基本健康信息(1)访谈（健康状况、病史、体育活动状况、生活环境等）；(2)测量血压；(3)形体测量和身体成分测量(身高、体重、BMI、腰围、体脂量（卡尺法）、肌肉量（PhysionXP、Physion）。2. (1)每日总能量消耗（DLW法）；(2)基础代谢（晨起、过期气法）。3. (1)加速度运动仪（松下和ICC，三轴，多轴，铃木，单轴）；(2)活动时间调查（调查人员对老年人修正的Koebnick公式）。4. 饮食(受试者在DLW研究期间摄入的所有食物和饮料均被记录并拍照，并使用Wellness 21（TopBusiness）计算营养价值。2006年，对36名健康老年人（男14名，女18名，年龄64-87岁）进行了研究，测定了日本健康老年人的能量消耗（总能量消耗、基础代谢、PAL）及其日常活动对总活动水平的影响。2007年，对16名健康水平较低的老年人（8名男性和8名女性，年龄在68-98岁之间）进行了类似的测量和调查。这两年的研究提供了有关日本老年人能量消耗的数据，这些老年人在年龄和健康水平上存在很大差异。特别是老年人的活动水平与非运动活动时间（NEAT）密切相关。少

In this2-year project, we aimed to evaluate the physical activity level in the Japanese elderly. We measured the total energy expenditure in elderly people ranging from early to late old age varying in the fitness level and state of health by the doubly-labeled water (DLW) method and evaluated the precision of, and problems with, various simplified methods.The items measured or investigated were : 1. Basic health information (1) Interviewing (state of health, history of diseases, state of physical activities, living environment, etc.) ; (2) Measurement of the blood pressure ; (3) Morphometry and body composition measurements (height, body weight, BMI, waist girth, body fat mass (calipers method), muscle mass (PhysionXP, Physion). 2. Metabolic parameters (1) Tbtal daily energy expenditure (DLW method); (2) Basal metabolism (on waking up in the morning, expired gas method). 3. Physical activity level measured by simplified methods (1) Acceleration activity meters (Matsushita and ICC, tri … More axial ; Suzuken, monoaxial) ; (2) Activity time survey (Koebnick's formula modified by the investigators for elderly people). 4. Diet (All food and beverages consumed during the DLW study period were recorded and photographed by the subjects, and nutritional values were calculated using Wellness 21(TopBusiness).In 2006,36 healthy elderly people (14 males and 18 females aged 64-87 years) were studied, and the energy expenditure (total energy expenditure, basal metabolism, PAL) of healthy Japanese elderly people and their daily activities affecting the total activity level were determined. In 2007, similar measurements and investigations were performed in 16 elderly people at a low fitness level (8 males and 8 females aged 68-98 years). Research over these 2 years provided data concerning the energy expenditure of Japanese elderly peoplevaryingwidely in ageand fitness level. Particularly, the activity level in elderly people was closely correlated with the non-exercise activity time(NEAT). Less
