The paper presents an assessment of the practicability of four software applications selected from those available in the Polish market to estimate and analyze energy expenditure in the context of their usefulness in design and organization of workplace in enterprises operating in Poland. Research questions are formulated, physiological, regulatory and functional guidelines are discussed, based on which assessment criteria are developed. Presented are averaged results of the rating performed independently by three experts and five occupational safety and health officers employed at different manufacturing plants. The study showed that none of the applications satisfied a majority of the developed criteria at once. They are mainly useful for estimating energy expenditure for male workers but they do not provide a full representation of compliance with the current statutory regulations. Further, independent analysis based on the records of generated results is either incomplete or hindered by the imposed way of value entry which requires that additional calculations be first performed. Based on the results of a comparative analysis of the functionalities offered by the applications, guidelines for software applications yet to be developed for estimating and analysis of human energy expenditure at the workplace are proposed.

W artykule przedstawiono ocenę możliwości wykorzystania czterech wybranych, spośród dostępnych na polskim rynku, aplikacji komputerowych służących do szacowania i analizy wydatku energetycznego w kontekście ich przydatności do organizacji i projektowania stanowisk pracy w przedsiębiorstwach działających na terenie polskim. Sformułowane zostały pytania badawcze oraz przedstawiono wytyczne fizjologiczne, prawne oraz użytkowe, na podstawie których opracowano kryteria oceny. Zaprezentowano uśrednione wyniki oceny, którą przeprowadziło niezależnie trzech ekspertów oraz pięciu pracowników służby bezpieczeństwa i higieny pracy, zatrudnionych w różnych przedsiębiorstwach produkcyjnych. Przeprowadzone badania udowodniły, że żadna z aplikacji nie spełnia naraz większości z opracowanych kryteriów. Nadają się one głównie do obliczeń wydatku energetycznego pracownika płci męskiej, ale nie dają pełnego obrazu na temat spełnienia wytycznych fizjologicznych ani aktualnych wymagań prawnych. Ponadto samodzielna analiza na podstawie uzyskanych zapisów jest albo niepełna z powodu braku możliwości wprowadzania wszystkich wymaganych danych, albo utrudniona przez taki sposób podawania wartości, który wymaga dodatkowych obliczeń.

Celem badań było porównanie wydatku energetycznego trzech rodzajów treningów podej-mowanych przez sportowców trenujących amatorsko siatkówkę, badmintona lub karate. W badaniu wzięło udział 36 osób (23 mężczyzn i 13 kobiet), w wieku 39 ±8 lat. Do oceny wy-datku energetycznego sesji treningowych wykorzystano pulsometry Polar M400 z nadajnikami na klatkę piersiową H7. Wydatek energetyczny treningu badmintona (1261 kcal; 631 kcal/h) i karate (1239 kcal; 823 kcal/h) był istotnie wyższy niż wysiłek siatkarski (868 kcal; 579 kcal/h). Z uwagi na znaczną wielkość wydatku energetycznego związanego z pojedynczą sesją treningową sportowców amatorów, uzasadnione wydaje się dalsze monitorowanie zarówno wielkości wydatku energetycznego sportowców amatorów, jak też wartości energetycznej ca-łodziennych racji pokarmowych tych osób.

The aim of the study was to compare energy expenditure during three amateur athletes trainings, ie. volleyball, badminton and karate. The study was conducted among 36 adults (23 men and 13 women), aged 39 ±8. Polar M400 heart rate monitors with H7 chest strap were used to estimate energy expenditure during selected training sessions. Energy expenditure dur-ing badminton (1261 kcal; 631 kcal/h) and karate (1239 kcal; 823 kcal/h) trainings were sig-nificantly higher than energy expenditure during volleyball training (868 kcal; 579 kcal/h). Due to the large energy expenditure during single training session, it seems justified to assess both energy expenditure and energy intake among athletes.

Objectives The aim of the study is to evaluate the intensity of the effort and energy expenditure in the course of performing selected classical massage techniques and to assess the workload of a massage therapist during a work shift. Material and Methods Thirteen massage therapists (age: 21.9±1.9 years old, body mass index: 24.5±2.8 kg×m⁻², maximal oxygen consumption × body mass⁻¹ ($\text{VO}_\text{2max}$×BM⁻¹): 42.3±7 ml×kg⁻¹×min⁻¹) were involved in the study. The stress test consisted in performing selected classical massage techniques in the following order: stroking, kneading, shaking, beating, rubbing and direct vibration, during which the cardio-respiratory responses and the subjective rating of perceived exertion (RPE) were assessed. Intensity of exercise during each massage technique was expressed as % $\text{VO}_\text{2max}$, % maximal heart rate ($\text{HR}_\text{max}$) and % heart rate reserve (HRR). During each massage technique, net energy expenditure (EE) and energy cost of work using metabolic equivalent of task (MET) were determined. Results The intensity of exercise was 47.2±6.2% as expressed in terms of % $\text{VO}_\text{2max}$, and 74.7±3.2% as expressed in terms of % $\text{HR}_\text{max}$, while it was 47.8±1.7% on average when expressed in terms of % HRR during the whole procedure. While performing the classical massage, the average EE and MET were 5.6±0.9 kcal×min⁻¹ and 5.6±0.2, respectively. The average RPE calculated for the entire procedure was 12.1±1.4. During the performance of a classical massage technique for a single treatment during the study, the average total EE was 176.5±29.6 kcal, resulting in an energy expenditure of 336.2±56.4 kcal×h⁻¹. In the case of the classical massage technique, rubbing was the highest intensity exercise for the masseur who performed the massage ($\text{%VO}_\text{2max}$ = 57.4±13.1%, $\text{HR}_\text{max}$ = 79.6±7.7%, HRR = 58.5±13.1%, MET = 6.7±1.1, EE = 7.1±1.4 kcal×min⁻¹, RPE = 13.4±1.3). Conclusions In the objective assessment, physical exercise while performing a single classical massage is characterized by hard work. The technique of classical massage during which the masseur performs the highest exercise intensity is rubbing. According to the classification of work intensity based on energy expenditure, the masseur’s work is considered heavy during the whole work shift. Int J Occup Med Environ Health 2018;31(5):677–684

ObjectivesThis study examined the physiological strain experienced by workers employed in motor-manual timber harvesting performed in winter and summer, and the applicability of heart rate indices for estimating energy expenditure.Material and MethodsThe heart rates (HR) of 2 teams consisting of 2 persons working simultaneously during felling and forwarding, in both winter and summer, were measured. Heart rate at work (HRwork), resting heart rate (HRrest), relative heart rate (%HRR), ratio of working heart rate to resting heart rate, and 50% level were used to estimate the physiological workload in particular jobs. The HRindex (HRwork/HRrest) equation was used to estimate the energy expenditure (EE). ResultsFor all jobs, significantly higher physiological workload and energy expenditure were recorded during winter.ConclusionsThe season significantly affects the physiological workload during logging operations. If there is no possibility of harvesting wood in summer, in order to limit the workload of workers during winter activity, attention should be paid to the proper organization of work and selection of workers.

ObjectivesPhysical activity (PA) is important for the prevention and management of numerous diseases and may have a positive effect on ability to work. The study aimed to assess the level of occupational and leisure time PA of soldiers during the COVID-19 pandemic and to explore whether there was a relationship between PA and perceived work ability.Material and MethodsThe study involved 305 men and 68 women who were territorial army soldiers aged 18–55 (M±SD 32.9±9.01). The Seven-Day Physical Activity Recall (SDPAR) and the Work Ability Index (WAI) were used.ResultsThe level of self-reported PA for the studied soldiers was relatively high; 80% of them met the recommendations of the WHO and were characterized by having a good (60%) or excellent (20%) WAI status. The level of occupational PA of male soldiers was higher than the level of leisure time PA, and they indicated higher levels of occupational PA and leisure time PA during the workweek than the weekend.ConclusionsCurrent work ability in comparison to the best in life and work ability related to the physical requirements of the work were positively correlated with leisure time PA. Work ability related to physical requirements was also positively correlated with occupational and total PA, and work ability related to mental requirements was positively correlated with total PA. The study supports the relationship between PA and several aspects of work ability.

Objectives Individual protection against contamination is the kind of protection provided to persons in an environment contaminated with radioactive substances, and war toxic or biological agents, including the use of gas masks, and insulating or filtration skin protection agents. The aim of this work was to perform a comparative assessment of energy expenditure of chemical troop soldiers wearing L-2 insulating personal protective clothes (PPC) and FOO-1 filter-sorptive PPC during training in the training ground conditions. Surveys on the subjective assessment of comfort related to using the L-2 and FOO-1 PPC were carried out as well. Material and Methods A total of 29 men doing the same training tasks, wearing the L-2 PPC and FOO-1 filter-sorptive protective clothing with an MP-5 filter gas mask, underwent the examination. Measurements of energy expenditure values were done based on the frequency of heart contractions, recorded by the Polar Sport Tester 810 heart rate monitor. Results It was found that an average energy expenditure of soldiers, resulting from performing training tasks, was lower among the subjects wearing the FOO- 1 filter-sorptive PPC, compared to the energy load of the ones using the L-2 PPC. Conclusions According to Christensen’s classification of work severity, the average energy expenditure makes it possible to qualify works performed by soldiers using both types of PPC to moderate work. In the opinion of the examined soldiers serving in the chemical troops, the FOO-1 filter-sorptive PPC increases the sense of security while on a threatened ground. The FOO-1 filter-sorptive PPC is assessed by chemical troop soldiers as better because it hinders tasks fulfillment to a lesser extent. Int J Occup Med Environ Health. 2019;32(5):645–52
