装卸工人负荷量与心率关系现场试验

Studies on The Relationship between Load Level and Pulse Rate of Loader

本文报道12名装卸工人负重心率关系的现场试验结果,应用方差及回归分析方法对比七个因素和二项指标进行了统计分析。通过多因素分析,找出了主要影响因素。试验结果表明,今后制定全国标准时除应考虑性别、负重量外,还应考虑负重方式、道路坡度以及生理参数(体表面积等)等因素。

The relationship between load level and pulse rate of 12 loaderswere studied.Analysis of the variance and stepwise regression analysiswere applied to the data of seven factors and three indices.Throughmultiple factor analysis the main influential factors were found.Experimental result indicated that load style,road slope and so onshould be considered besides sex and load level during the setting ofload standard.
