Galileo Galilei’s quote ‘ measure what is measurable, and make measurable what is not so ’ has particular relevance to health behaviours, such as physical activity (PA), sitting and sleep, whose measurement during free living is notoriously difficult. To date, much of what we know about how these behaviours affect our health is based on self-report by questionnaires which have limited validity, are prone to bias and inquire about selective aspects of these behaviours. Although self-reported evidence has made great contributions to shaping public health and exercise medicine policy and guidelines until now,1 the ongoing advancements of accelerometry-based measurement and evidence synthesis methods are set to change the landscape. The aim of this editorial is to outline new directions in PA and sleep-related epidemiology that open new horizons for guideline development and improvement; and to describe a new research collaboration platform: the Prospective Physical Activity, Sitting, and Sleep consortium (ProPASS) (figure 1). Figure 1 Measurement technology used in epidemiology has made measurable what was not so until recently. Several population-based studies use accelerometers that are worn by participants for 24 hours a day for a whole week, offering unprecedented insights into the health attributes of PA, sitting and sleep. One of the most exciting aspects of accelerometers is that they show great promise for capturing nearly complete accounts of movement behaviour, including posture and activity type detection.2 However, advanced measurement methods and optimal evidence synthesis are not synonymous.

下一代体育活动、睡眠和运动医学指南的新兴合作研究平台：前瞻性体育活动、坐姿和睡眠联盟 (ProPASS)

伽利略·伽利莱 (Galileo Galilei) 的名言“衡量什么是可衡量的，让不可衡量的东西可衡量”与健康行为特别相关，例如身体活动 (PA)、坐姿和睡眠，在自由生活期间，这些行为的衡量是非常困难的。迄今为止，我们对这些行为如何影响我们健康的了解大部分是基于问卷的自我报告，这些问卷的有效性有限，容易产生偏见并询问这些行为的选择性方面。尽管迄今为止，自我报告的证据对制定公共卫生和运动医学政策和指南做出了巨大贡献1，但基于加速度计的测量和证据合成方法的不断进步将改变这一局面。本社论的目的是概述 PA 和睡眠相关流行病学的新方向，为指南的制定和改进开辟新的视野；并描述一个新的研究合作平台：前瞻性身体活动、坐姿和睡眠联盟 (ProPASS)（图 1）。图 1 流行病学中使用的测量技术使直到最近才可以测量的东西变得可测量。几项基于人群的研究使用加速度计，参与者每天 24 小时佩戴一整周，为 PA、坐姿和睡眠的健康属性提供了前所未有的见解。加速度计最令人兴奋的方面之一是它们在捕捉几乎完整的运动行为记录方面显示出巨大的潜力，包括姿势和活动类型检测。 2 然而，先进的测量方法和最佳证据合成并不是同义词。个人 …
