目的
本文综述了体力活动评价方法的有效性以及体力活动能量消耗与肥胖关系的研究，并提出了进一步研究的建议。
设计
评估了双标记水评估身体活动的现场方法的验证研究，讨论了双标记水评估的活动能量消耗与肥胖之间关系的研究。
方法
三个领域的方法进行评估的身体活动，验证与双标记水作为一个标准的方法，包括：活动问卷，心率监测和运动传感器。
结果
三轴加速度计是评估身体活动的最佳现场方法，其次是Baecke活动问卷。大多数肥胖受试者是适度活跃的，并且肥胖受试者的活动水平的增加受到进行更高强度运动的能力的限制。
结论
加速度计是一种客观的工具，用于在足够长的时间内评估大量人群的身体活动，以代表正常的日常生活，并使受试者的不适最小。加速度计可用于区分个体之间的活动水平差异，并评估干预措施对个体身体活动的影响。
PURPOSE
Validations of methods for the assessment of physical activity and studies on the relation between energy expenditure of activity and obesity were reviewed, with suggestions for further research.
DESIGN
Validation studies of field methods for the assessment of physical activity against doubly labeled water were evaluated, studies on the relation between doubly labeled water assessed energy expenditure of activity and obesity are discussed.
METHODS
Three field methods for the assessment of physical activity, validated with doubly labeled water as a criterion method, were included: activity questionnaires, heart rate monitoring, and motion sensors.
RESULTS
The triaxial accelerometer came out as the best field method for the assessment of physical activity, followed by the Baecke activity questionnaire. The majority of obese subjects are moderately active, and an increase in the activity level of obese subjects is limited by the ability to perform exercise of higher intensity.
CONCLUSIONS
Accelerometers are an objective tool for the assessment of physical activity in large populations over periods long enough to be representative for normal daily life and with minimal discomfort to the subjects. The accelerometer can be used to distinguish differences in activity levels between individuals and to assess the effect of interventions on physical activity within individuals.
