各种研究都需要估计每日能量消耗的数量和模式。为此，制定了为期3天的活动记录，并对其进行了描述。在包括周末在内的3天内，每15分钟的能源成本符合1至9级标准，对应于1.0至7.8兆赫或更高的范围。一项对61名受试者的可靠性研究表明，这是一种重复性很高的程序，3天内能量消耗的平均大卡的组内相关性为0.96。无论记录中是否包括睡眠时间，重复性都没有变化。150名儿童和150名成年人的样本也被抽出，以调查能量消耗、体力工作能力和身体肥胖之间的关系。结果支持单位体重平均能量消耗与单位体重体力工作能力显著相关的假设(r=0.31；P<；0.01)。每公斤体重的平均能量消耗与体脂呈负相关(-0.08。R.ltoreq。-0.13)。3天活动记录是一种适合于人口研究中估算能量消耗的程序。
A variety of studies has a need to estimate the amount and pattern of daily energy expenditure. To this end, a 3-day activity record was developed and is described. Every 15-min period over 3 days, including a weekend day, was qualified in terms of energy cost on a 1 to 9 scale corresponding to a range of 1.0 MET to 7.8 MET and higher. A reliability study of 61 subjects indicated a highly reproducible procedure as shown by an intraclass correlation of 0.96 for mean kcal of energy expenditure over 3 days. Repeatability was unchanged whether or not the hours of sleep were included in the record. Samples of 150 children and 150 adults were also drawn to investigate the relationship between energy expenditure, physical working capacity, and body fatness. Results support the hypothesis that mean energy expenditure per kg of body weight is significantly correlated with physical working capacity expressed per kg of body weight (r = 0.31; P < 0.01). Mean energy expenditure per kg of body weight is negatively related to body fat (-0.08 .ltoreq. r .ltoreq. -0.13). The 3-day activity record is a procedure suitable to estimate energy expenditure in population studies.
