Abstract

Objective: To analyze the effects of vertical height and lifting frequency on the physiological response in workers during lifting of loads.

Methods: Factorial experimental design with blocks, considering vertical height and lifting frequency as independent variables; the dependent variable was defined as the heart rate. The experiment was conducted in 20 workers between the ages of 18 and 40 years with at least six months of experience in warehouse and packaging tasks at a dairy products company. We calculated the FRIMAT coefficient to determine the physiological load of the task.

Results: We found a significant effect on the heart rate response due to the interaction of the rate and the vertical height of the lift. Based on the FRIMAT coefficient, we obtained a rating of "minimal workload" for 85% of the treatments; for one treatment there was a rating of "somewhat difficult."

Conclusions: Height and frequency of lift do not act separately and have an effect on the physiological load of the worker during manual lifting, reflected by changes in the heart rate.

【心率与人工举重高度和频率的关系分析】。

目的:分析升降高度和升降频率对工人升降时生理反应的影响。方法:以垂直高度和升降频率为自变量，采用块析因试验设计;因变量定义为心率。这项实验是在20名年龄在18岁到40岁之间的工人中进行的，他们在一家乳制品公司至少有6个月的仓库和包装工作经验。我们通过计算FRIMAT系数来确定任务的生理负荷。结果:我们发现由于速率和升降机垂直高度的相互作用，对心率反应有显著影响。根据FRIMAT系数，我们对85%的治疗获得了“最小工作量”的评级;其中一种治疗被评为“有些困难”。结论:升降高度和升降频率并不是单独作用的，它们对工人在手工升降过程中的生理负荷有影响，反映在心率的变化上。
