The present study compared the effect of fabric type of working clothes on heat strain responses in different levels of physical workload and under different kinds of weather conditions. Four kinds of working clothing fabric that are greatly popular in Iranian industry were assessed on 18 healthy male at 2 environments: hot and humid (dry temperature [DBt]: 35°C and relative humidity [RH]: 70%) and hot and dry (DBt: 40°C and RH: 40%). The physiological responses such as heart rate and core body temperature were reported. It was found that there were no significant differences between different types of clothing fabric on cardiac and physiological parameters. It can be recommended that 100% cotton clothing ensemble during low-workload activities and 30.2% cotton-69.8% polyester clothing ensemble during moderate-workload activities is used for Iranian workers to maintain the cardiac and physiological strains as low as possible.
本研究比较了不同工作负荷水平和不同天气条件下工作服面料类型对热应激反应的影响。在炎热潮湿(干球温度[DBt]:35°C,相对湿度[RH]:70%)和炎热干燥(DBt:40°C,RH:40%)两种环境下,对18名健康男性评估了伊朗工业中广泛使用的四种工作服面料。记录了心率和核心体温等生理反应。结果发现,不同类型的服装面料在心脏和生理参数方面没有显著差异。建议伊朗工人在低负荷活动期间穿着100%纯棉服装,在中等负荷活动期间穿着含30.2%棉和69.8%聚酯的服装,以尽可能降低心脏和生理应激。
