身体活动是一种行为，其特征是任何身体运动，导致能量消耗增加超过休息水平（Caspersen，1989）。这种行为与降低过早死亡（Haskell，1994）和几种疾病的风险有关，如心脏病、某些类型的癌症、非胰岛素依赖型糖尿病、高血压和骨质疏松症（Haskell，1994）。然而，目前还不清楚需要多少体力活动才能降低这些疾病的风险。有一些风险因素与健康风险增加有关，特别是冠心病。高血压、高血压、吸烟和肥胖都在研究文献和大众媒体中受到广泛关注，因为它们会增加冠心病的风险。所有这些“风险因素”都相对容易量化，无论是在家里还是通过常规的医疗检查程序。此外，这些措施每天都表现出相当高的稳定性。然而，身体活动行为的评估更难描述，因为它是基于个人的习惯和做法，每天变化很大。通常自我报告的措施是用来评估身体活动，通常是受回忆错误和不准确的看法一个人的活动行为。随着目前公共卫生对暴露的重视（即，积累30分钟的中等强度体力活动），我们必须使用更客观的方法来量化这一点。
Physical activity is a behavior that is characterized by any bodily movement that results in an increase in energy expenditure above resting levels (Caspersen, 1989). This behavior has been linked to a reduced risk of premature mortality (Haskell, 1994) and several diseases such as heart disease, certain types of cancer, noninsulin dependent diabetes mellitus, hypertension, and osteoporosis (Haskell, 1994). However, it is not clear how much physical activity is required to reduce risk for these diseases.There are a number of risk factors that have been linked to increased health risk, particularly for coronary heart disease. Hyperlipidemia, hypertension, smoking, and obesity have all received widespread attention in the research literature as well as in the popular press as increasing one's risk for coronary heart disease. All of these'risk factors' are relatively easy to quantify either at home or through routine medical examination procedures. In addition, these measures exhibit a fairly high degree of stability day-to-day. However, assessment of physical activity behavior is much more difficult to characterize as it is based on individual habits and practices that vary considerably day-to-day. Often self-report measures are used to assess physical activity and are commonly subject to recall errors and inaccurate perception of one's activity behavior. With the current public health emphasis on the exposure (ie, accumulating 30 minutes of moderate intensity physical activity), it becomes imperative that we use more objective methods for quantifying this be-
