The aim of this study was to determine what proportion of occupationally active Poles have working capacity that enables them to tolerate hard and very hard physical work. For this purpose physical capacity of 1188 occupationally active subjects (524 women and 664 men), aged 18-64 years was examined. Their maximal oxygen consumption (VO2max) was determined indirectly on the basis of their heart rate during an incremental exercise test on a bicycle ergometer. It was found that hard occupational physical work was an excessive load for almost 40% of men and women. This paper discusses how this load should be decreased with planned, appropriately long rest breaks. The percentage of persons for whom their hard physical work becomes an excessive load increases with age to such a degree that a new assessment of individual capability for such work is recommended for persons over 40 years old.
本研究旨在确定有多少在职波兰人具有能够承受艰苦和极艰苦体力劳动的工作能力。为此，对 1188 名在职受试者（524 名女性和 664 名男性）的身体能力进行了检查。他们的最大耗氧量（VO2max）是根据他们在自行车测力计上进行递增运动试验时的心率间接确定的。结果发现，几乎 40%的男性和女性从事艰苦的职业体力劳动是一种过重的负担。本文讨论了如何通过计划的、适当长的休息时间来减少这种负荷。从事艰苦体力劳动的人所占的比例随着年龄的增长而增加，以至于建议 40 岁以上的人对其从事此类工作的个人能力进行新的评估。
