“…Heart rate and its derivatives (e.g. heart rate variability) are markers for cardiovascular disease, and have been studied previously in shift-workers [14,15,32]. Increased heart rate can be interpreted as an indicator for increased sympathetic stress to the heart, especially when heart rate is increased in the mornings and in resting positions.…”

Objective:The aim of this study was to identify atherosclerotic risk using pulse wave velocity (PWV) in steel workers employed in different shift-work rotations, and to elucidate its relationship to social jetlag and shift schedule details. Participants:Male workers in a steel factory (n = 77, 32 fast clockwise (CW), 30 slow counterclockwise (CC), 15 day workers (DW); mean age 42 ± SD 7.6 yrs) with at least 5 years experience in their current work schedule participated.Methods: All workers completed questionnaires on demographics, health, stimulants, sleep, social and work life, social jetlag (difference between mid-sleep time on workdays and days off used as a marker of circadian disruption) and chronotype (midsleep time on free days corrected for sleep deficit on workdays). In 63 workers we measured PWV, blood pressure (BP), heart rate (HR) between 08:00 and 12:30 h in controlled posture conditions (no caffeine/smoking/exercise).Results: There was no significant difference in PWV (covariates: age, BP) between the different shift-rotations (CW, CC and DW). In all workers combined HR and social jetlag were significantly positively correlated. Although demographic variables did not differ between shift-workers and day workers, the shift-workers (CW, CC) reported significantly more stomach upsets, digestion problems, weight fluctuations, 2 and social jetlag. The CW and CC workers did not differ in ratings of how shift-work affected sleep, social and work life. Conclusions:Although PWV was not different between the two shift-rotations, this pilot study shows first evidence that HR is related to social jetlag, and warrants more studies in different shift schedules.

“…In general, heart rate increases during work, which is evidenced, for example, in a study of 500 men in the petrochemical industry, where a significant connection between work strain and a high resting heart rate ≥ 90 beats/min was found [56]. An increase in heart rate during work was also proven by a study in which it was proven that the average heart rate of workers in a paper mill was higher during work than when the worker was at rest [57]. If the operator smoked, the heart rate could also be affected, but as [58] mentions in his study, smoking probably plays a secondary role.…”

The aim of this work was to determine the dependence of the heart rate of operators of forwarding machines on the activities performed during the working day within the framework of timber forwarding and to compare individual activities in terms of the level of physical workload. For this purpose, the work shift of operators carrying out timber forwarding was divided into individual activities: driving, maintenance, forwarding, and break. During these work activities, the heart rate of each operator was taken for subsequent evaluation. A portable device, a Garmin smartwatch, was used to measure their heart rate. The results show that the highest pulse rates of the operators occurred during the maintenance of the entrusted machine, while the highest pulse fluctuations were recorded during forwarding. During this activity, the highest heart rate of the entire measurement process was recorded (132.0000 bpm), but also the lowest (42.0000 bpm). Furthermore, it was proven that both the operator and the activity he performs affect the pulse rate. The activities themselves did not differ from each other in only one of the six cases of comparison, specifically, between driving and forwarding.

“…Indirect calorimetry was employed as an EC assessment method in a total of 44 studies as follows: 14 studies in agriculture22,23,24,25,26,27,28,29,30,31,32,33,34,35 ) , 5 studies in construction36,37,38,39,40 ) , 14 studies in manufacturing23, 41, 42,43,44,45,46,47,48,49,50,51 ) (some papers include more than one study), and 13 studies in transportation22, 52,53,54,55,56,57,58,59,60,61,62,63 ) . The heart rate monitoring method was used to assess workers’ EC in 10 studies as follows: one study in the tourism industry64 ) , seven studies in the manufacturing industry65,66,67,68,69,70,71 ) , and two studies in the transportation industry72, 73 ) . Time motion analysis was used as an EC assessment method in three studies as follows: one study in the tourism industry74 ) and two studies in the agriculture industry5, 27 ) .…”

“…Despite our best intentions, it is important to note that the EC estimates provided in this paper should be considered through the prism of certain limitations. For instance, while some studies (e.g., Bielski69 ) , Brun30 ) , and Abdelhamid40 ) ) provide a comprehensive description of several tasks included in each job, other papers (e.g., Inoue65 ) , Davies29 ) , and Moharana64 ) ) provide only a single-phrase description or a job title. While we addressed the fact that the number of workers assessed in each study were different, by weighing the EC estimates provided for each NACE code, it is important to note that most of the studies assessed few or no women workers.…”

Metabolic energy cost of workers in agriculture, construction, manufacturing, tourism, and transportation industries

The assessment of energy cost (EC) at the workplace remains a key topic in occupational health due to the ever-increasing prevalence of work-related issues. This review provides a detailed list of EC estimations in jobs/tasks included in tourism, agriculture, construction, manufacturing, and transportation industries. A total of 61 studies evaluated the EC of 1667 workers while performing a large number of tasks related to each one of the aforementioned five industries. Agriculture includes the most energy-demanding jobs (males: 6.0 ± 2.5 kcal/min; females: 2.9 ± 1.0 kcal/min). Jobs in the construction industry were the 2nd most demanding (males: 4.9 ± 1.6 kcal/min; no data for females). The industry with the 3rd highest EC estimate was manufacturing (males: 3.8 ± 1.1 kcal/min; females: 3.0 ± 1.3 kcal/min). Transportation presented relatively moderate EC estimates (males: 3.1 ± 1.0 kcal/min; no data for females). Tourism jobs demonstrated the lowest EC values (2.5 ± 0.9 kcal/min for males and females). It is hoped that this information will aid the development of future instruments and guidelines aiming to protect workers' health, safety, and productivity. Future research should provide updated EC estimates within a wide spectrum of occupational settings taking into account the sex, age, and physiological characteristics of the workers as well as the individual characteristics of each workplace.
