目的测量工人和学生两组人群的最大肌力,为制定适合我国人群的手工搬举标准提供依据。方法按照《人体测量学指导手册》测定938名受试者的基本人体尺寸,通过拉力测试系统测定受试者的背提力、左右手提力、手臂提力和肩提力。结果测得男性背提力、左右手提力、手臂提力、肩提力的最大值男性分别为1 077.0、576.9、609.0、318.3、465.1N,女性分别为602.0、306.6、340.9、181.8、252.3N。背提力最大,手臂提力最小。男性受试者人体尺寸和最大肌力呈现一定的相关性(P<0.05)。结论中国人背提力、单手提力、手臂提力和肩提力均低于欧美人群。女性各种肌力均比男性小,总体上是男性肌力的55%左右。在女性当中左手肌力小于右手肌力更加明显。
Objective To measure the maximum strength of two groups of workers and students and to provide the basis for setting the standard of manual removal suitable for the Chinese population. Methods The basic body size of 938 subjects was determined according to the “Guide to Anthropometry” and the back force, left hand and right hand power, arm strength and shoulder power of the subjects were measured by the tension test system. Results The maximum values of men’s back force, left hand lift, arm lift and shoulder lift were 1 077.0, 576.9, 609.0, 318.3, 465.1N respectively, and women were 602.0, 306.6, 340.9, 181.8, 252.3N . Back lift the largest arm lift the smallest. There was a correlation between body size and maximum muscle strength in male subjects (P <0.05). Conclusions Chinese people have lower back lift, single lift, arm lift and shoulder lift than those in Europe and the United States. Women of all kinds of muscle strength than men, overall, about 55% of male muscle strength. In women, left-handed muscle strength is more obvious than the right-handed muscle.
