摘　　要：采用心理物理学法,通过获取最大可接受质量(MAWL)、心率与用力感受自我评分等参数,研究了健康青年人不同提举参数组合下的手工提举能力.结果表明:提举高度、提举频率与水平距离3个提举参数及其交互作用均能显著影响青年人的提举质量,提举质量随3个参数的增加而降低;提举在相同任务中,男女的生理反应与身体各部位的用力程度存在差异.The manual lifting capacity was evaluated by the psychophysical approach under different integrations of lifting parameter,and the youth＇s maximum acceptable weight of lift（MAWL）,heart rate and rating of perceived exertion were obtained. The results indicated that three lifting parameters and their interaction effects, which included lifting heights, frequencies and horizontal distance, had significant influence on the youth＇s manual lifting wight. The lifting weight decreased with the increase of three lifting parameters. In identical lifting task,the male and female＇s physiologic reaction and the exertion level of various parts of the body have differences in manual lifting.
