Despite extensive use over 40 years, physical activity questionnaires still show limited reliability and validity. Measurements have value in indicating conditions where an increase in physical activity would be beneficial and in monitoring changes in population activity. However, attempts at detailed interpretation in terms of exercise dosage and the extent of resulting health benefits seem premature. Such usage may become possible through the development of standardised instruments that will record the low intensity activities typical of sedentary societies, and will ascribe consistent biological meaning to terms such as light, moderate, and heavy exercise.
尽管在过去40多年里被广泛使用,但身体活动问卷的可靠性和有效性仍然有限。这些测量在指出增加身体活动有益的情况以及监测人群活动变化方面具有价值。然而,就运动剂量和由此产生的健康益处程度进行详细解读的尝试似乎还为时过早。通过开发标准化工具,记录久坐社会典型的低强度活动,并为轻度、中度和重度运动等术语赋予一致的生物学意义,这种应用才有可能实现。
