本研究的目的是量化工业甘蔗的体力劳动者的生理工作量，并评估接受休息，阴凉和水合作用干预，以减少热应激暴露风险的影响。在一项观察性研究中，使用在整个工作班次中连续记录的心率（HR）（Polar®）评估了烧伤甘蔗收割机（BCC）、种子收割机（SC）和滴灌修复工人（DIRW）的生理工作负荷。计算工人的最大HR百分比（%HRmax），在不同HR区花费的时间和估计的核心温度（ECTemp）。对BCC和SC在两次收获中增加休息的效果进行了评价。共有162名工人参加了本研究[52名BCC（均为男性），71名SC（13名女性）和39名DIRW（16名女性）]。BCC和SC之间的轮班平均%HRmax相似（BCC：58%，SC：59%），但DIRW较低（51%）。BCC和SC在艰苦/非常艰苦的强度下工作的轮班比例相似（BCC：13%，SC：15%），而DIRW主要在轻度（46%）或轻度-中度（39%）强度下工作。SC最大ECTemp达到38.2°C，BCC 38.1°C;而DIRW仅达到37.7°C。在轮班工作中，女性的%HRmax高于男性（SC 64% vs 58%; DIRW 55% vs 49%）。在BCC中，额外的休息时间与整个工作班次中较低的平均%HRmax相关。在这种情况下，BCC和SC都承担非常生理要求的工作。女性的工作量高于男性同事。每小时有规律的休息时间，有水和阴凉处，似乎可以减少生理工作量/压力。
The aim of this study was to quantify the physiological workload of manual laborers in industrial sugarcane and assess the effect of receiving a rest, shade, and hydration intervention to reduce heat stress exposure risk. In an observational study, physiological workload was evaluated for burned cane cutters (BCC), seed cutters (SC) and drip irrigation repair workers (DIRW) using heart rate (HR) recorded continuously (Polar®) across a work shift. Workers’ percentage of maximal HR (%HRmax), time spent in different HR zones, and estimated core temperature (ECTemp) were calculated. The effect of increasing rest across two harvests was evaluated for BCC and SC. A total of 162 workers participated in this study [52 BCC (all male), 71 SC (13 female) and 39 DIRW (16 female)]. Average %HRmax across a work shift was similar between BCC and SC (BCC: 58%, SC: 59%), but lower in DIRW (51%). BCC and SC spent similar proportions of work shifts at hard/very hard intensities (BCC: 13%, SC: 15%), versus DIRW who worked mostly at light (46%) or light-moderate (39%) intensities. SC maximum ECTemp reached 38.2°C, BCC 38.1°C; while DIRW only reached 37.7°C. Females performed at a higher %HRmax than males across work shifts (SC 64% versus 58%; DIRW 55% versus 49%). An additional rest period was associated with a lower average %HRmax across a work shift in BCC. In this setting, BCC and SC both undertake very physiologically demanding work. Females maintained a higher workload than male co-workers. Regulated rest periods each hour, with water and shade access, appears to reduce physiological workload/strain.
