Abstract
The energy cost of activity, depending on its intensity, varies between 6 and 50 kJ min-1 with average values for essential daily tasks and for hard work respectively of 12 and 28 kJ min-1. The levels of ventilation required to sustain these activities are, on average, 15 and 33 1 min-1 with an overall range of +/- 30%. Additional ventilation is needed for speech. The requirements for individual activities are reviewed.
摘要
活动的能量消耗取决于其强度，在6至50千焦/分钟之间变化，日常基本任务和繁重工作的平均值分别为12和28千焦/分钟。维持这些活动所需的通风水平平均分别为15和33升/分钟，总体范围为±30%。说话还需要额外的通风。文中对各项活动的要求进行了综述。
