标准范围

代谢率是化学能转化为机械能和热能的一种形式，衡量肌肉负荷的能量消耗，并给出活动的数值指标。代谢率是舒适度或暴露在热环境中产生的压力的重要决定因素。特别是在炎热的气候下，与肌肉工作相关的高水平代谢热会加剧热应激，因为大量热量需要消耗，主要是通过汗液蒸发。ISO 8996:2004规定了在气候工作环境的人类工效学背景下测定代谢率的不同方法。它还可以用于其他应用——例如，工作实践评估、特定工作或体育活动的能量成本、活动的总成本等。

The metabolic rate, as a conversion of chemical into mechanical and thermal energy, measures the energetic cost of muscular load and gives a numerical index of activity. Metabolic rate is an important determinant of the comfort or the strain resulting from exposure to a thermal environment. In particular, in hot climates, the high levels of metabolic heat production associated with muscular work aggravate heat stress, as large amounts of heat need to be dissipated, mostly by sweat evaporation.ISO 8996:2004 specifies different methods for the determination of metabolic rate in the context of ergonomics of the climatic working environment. It can also be used for other applications -- for example, the assessment of working practices, the energetic cost of specific jobs or sport activities, the total cost of an activity, etc.
