摘要
目的探讨中国青年男性的最大可接受提举重量，验证美国职业安全卫生研究所（NIOSH）提出的提举重量限值能否在中围应用。方法11名年轻男性大学生参加试验。通过心理物理学方法，获得不同提举频率下的最大可接受提举重量、心率和用力自我感受，提举高度为从地面到工作台（760mm）。结果与NIOSH建议值和美围利宝集团研究结果进行比较。结果年轻男性的一次最大可接受提举重量为34．1kg，而1、4、8次／min的最大可接受提举重量则分别为17.4、14．7、12．2kg。结果明显低于NIOSH的推荐限值。结论应用NIOSH提举公式时应作调整，如降低提举重量常数和提举频率系数等。
Objective To determine the maximum acceptable weight of lift （MAWL） in a Chinese young male population, and examine whether the revised weight limit recommended by the US. National Institute for Occupational Safety and Health can be used for Chinese workers. Methods Eleven young male college students participated in the experiment. The psyehophysieal approach was used to determine the MAWL with the different frequencies of lift, the heart rate and the self-evaluation. The weight was lifted from the floor to the worktable （760 mm）. The results were compared with the recommended weight limit （RWL） and the MAWL by Snook. Results The MAWL of young male was 34.1 kg while the MAWL with frequency of 1,4 and 8/min was 17.4, 14.7 and 12.2 kg respectively. The overall MAWL were lower than RWL of NIOSH and the results of Snook. Conclusion The NIOSH 1991 equation such as load constant and frequency multiple should be revised when the NIOSH limits is used in Chinese population.
