Physical activity guidelines for health recommend any type of unstructured physical activity for health promotion. Adults should perform at least 150-300 min per week of moderate intensity or 75-150 min per week of vigorous intensity activities, or an equivalent combination of the two intensities. However, the relationship between physical activity intensity and longevity remains a debated topic, with conflicting perspectives offered by epidemiologists, clinical exercise physiologists or anthropologists. This paper addresses the current known role of physical activity intensity (in particular vigorous versus moderate intensity) on mortality and the existing problems of measurement. Given the diversity of existing proposals to categorize physical activity intensity, we call for a common methodology. Device-based physical activity measurements (e.g., wrist accelerometers) have been proposed as a valid method to measure physical activity intensity. An appraisal of the results reported in the literature, however, highlights that wrist accelerometers have not yet demonstrated sufficient criterion validity when they are compared to indirect calorimetry. Novel biosensors and wrist accelerometers will help us understand how different metrics of physical activity relates to human health, however, all these technologies are not enough mature to provide personalized applications for healthcare or sports performance.
身体活动指南建议促进健康应进行任何类型的非结构化身体活动。成年人每周应至少进行 150-300 分钟中等强度或 75-150 分钟高强度活动，或这两种强度的等效组合。然而，身体活动强度与长寿之间的关系仍然是一个有争议的话题，流行病学专家、临床运动生理学家或人类学家提供了相互冲突的观点。本文探讨了当前已知的身体活动强度（特别是剧烈强度与中等强度）对死亡率的影响，以及现有的测量问题。鉴于现有的身体活动强度分类建议存在多样性，我们呼吁采用通用方法。基于设备的身体活动测量（例如，腕部加速度计）已被提议作为测量身体活动强度的有效方法。然而，对文献中报告的结果进行评估后发现，当与间接测热法进行比较时，腕部加速度计尚未显示出足够的标准效度。新型生物传感器和腕部加速度计将帮助我们了解身体活动的不同指标如何与人类健康相关，但所有这些技术还不够成熟，无法为医疗保健或运动表现提供个性化应用。
