    Opis:
    Lactic acidosis is a form of metabolic acidosis with a high anion gap, reduced rate of arterial blood pH under 7.35 mmol/l, and lactic acid concentration over 7 mmol/l. In the literature we can find some descriptions of the cases of lactic acidosis in patients with severe systemic diseases (cancer, acquired immunodeficiency syndrome, sepsis, diabetes with cardiovascular disease and after organ transplantations). We present the case of lactic acidosis in a patient with no chronic disease - a firefighter in whom lactic acidosis has developed during standard exercises in the smoke chamber.

    Objective: The aim of this study was to verify the influence of a specific exercise program on the strength and resistance levels of lumbar flexors and extensors in warehouse workers. Materials and Methods: The population used in this randomized controlled trial included 557 warehouse male workers from a food distribution company in Oporto/Portugal. Upon the application of the selection criteria, 98 workers deemed eligible were randomized in two groups: 57 were assigned to the intervention group and 41 to the control group. The intervention included 9 easily-executed exercises to promote stretching and strengthening of the lumbar region, to be executed daily, at the beginning of the working time, at the company facilities and lasting 8’. Trunk muscles’ voluntary strength and resistance were measured using an isometric electronic dynamometer (Globus Ergometer, Globus, Codigné, Italy) at baseline and eleven months after implementing the exercise program. The data was analyzed using SPSS®, version 17.0. Results: After implementation of the exercise program, in the intervention group, all variables increased, significant differences were observed as for the muscle strength and resistance values (p = 0.014 and p = 0.006, respectively), as well as in the ratio extensors/flexors (p = 0.037). In the control group, all variables decreased, with a statistically significant decrease of the trunk flexors strength level (p = 0.009). Conclusion: The results of this study suggest that a specific exercise intervention program can increase trunk extensors strength and resistance.

    ObjectivesThe physical activity level (PAL) has significantly decreased as a result of the social distancing and lockdown related to the COVID‑19 pandemic, but there is a lack of knowledge on the correlates of PAL during the pandemic. The aim of this research was to examine the influence of pre-pandemic sports participation and substance use and misuse (SUM) on PAL during the COVID‑19 pandemic.Material and MethodsThe study included 661 high-school students from Bosnia and Herzegovina (aged 15–18 years, 292 females). The investigation included 2 testing waves: before the COVID‑19 pandemic (baseline, January 2020) and during the COVID‑19 lockdown (follow-up, April 2020). The variables included PAL as measured by the Physical Activity Questionnaire for Adolescents, sports factors, and SUM.ResultsSports factors at baseline were positively correlated with PALs at both baseline and follow-up. Smoking tobacco negatively affected PALs at both baseline and follow-up. Alcohol consumption was positively correlated with PAL at baseline but had no effect on PAL at follow-up.ConclusionsThis study confirmed the importance of sports participation in maintaining PAL during challenging situations, such as the COVID‑19 lockdown. The substance-specific influence of SUM on PAL before and during the lockdown points to evident social and cultural aspects of SUM behaviors in adolescents. Further studies evidencing the cumulative effects of PAL decline during the lockdown are warranted.

    Opis:
    ObjectivesAmbient air pollution is related to adverse respiratory effects. Because of a popular habit of recreational physical activity, the effects of exposure to increased levels of air pollution attract increasing attention. It remains unclear whether the allergy status has an impact on acute responses to air pollution exposure during brief exercise in young adults. The aim of the study was to determine if acute respiratory responses to ambient air pollution during physical exercise differ between young subjects with and without a history of upper respiratory allergy.Material and MethodsOverall, 41 young males with (N = 15, 36.6%) and without allergy (N = 26, 63.4%) performed short moderate-intensive cycle-ergometer sessions in winter air pollution exposure conditions. Associations were analyzed between environmental conditions and acute physiological changes in spirometry, fractioned exhaled nitric oxide (FeNO) levels, blood pressure and pulse oximetry.ResultsNo associations between air pollution concentrations and changes in forced vital capacity, forced expiratory volume in 1 s and the Tiffeneau index were found. In the subjects without allergy, the increased air pollution concentrations recorded during exercise were associated with a post-exercise increase/a smaller decrease in FeNO (SO2: Spearman’s ρ = 0.44, NOx: ρ = 0.51, and particulate matter [PM] levels – PM10: ρ = 0.51, PM2.5: ρ = 0.52). This effect was not observed in the subjects with allergy.ConclusionsUpper-respiratory allergy may be a modifying factor in human response to air pollution during exercise. Exposure to air pollution during brief moderate-intensive exercise did not have any acute negative impact on respiratory and cardiovascular function in young males. However, in the case of FeNO, subclinical post-exercise changes related to air pollution were observed in volunteers without allergy.

    Opis:
    Objectives: The purpose of this study was to determine the level, pattern and correlates (socio-demographic, lifestyle and work-related) of physical activity among middle-aged employees in Croatia. Material and Methods: In this cross-sectional study the data were collected using a household interview on a random sample of 766 middle-aged employees (52% female) living in Croatia. The International Physical Activity Questionnaire (IPAQ-long) was used to assess physical activity. An additional questionnaire was used to collect data on socio-demographic, lifestyle and work-related correlates. Results: The median (95% CI) total physical activity for the whole sample was 78.7 (69.1-88.3) MET-hours/week. Most physical activity was accumulated in the domain of work (26.4 (20.3-32.5) MET-hours/week) or in domestic activities (19.2(17.8-20.7) MET-hours/week), whilst a significantly lower physical activity was found in the transport (3.3 (2.9-3.7) MET-hours/week) and leisure-time domains (6.5 (5.7-7.3) MET-hours/week). The multiple regression analysis showed an inverse relationship between educational level and the size of settlements with the domestic-related and total physical activity (β range: -0.11 to -0.22; p < 0.01). Among lifestyle correlates, only alcohol consumption was positively related to the total physical activity (β = 0.12; p < 0.01), while the perceived level of stress outside work was the only one, which was inversely associated with the work-related (β = -0.09; p < 0.01) and leisure-time physical activity (β = -0.10; p < 0.01). Conclusions: Middle-aged employees in Croatia accumulate most of their daily physical activity in the work and domestic domains. Analysis of the relationship between physical activity and potential socio-demographic, lifestyle, and work-related correlates indicated that physical activity promotional activities should be primarily focused on males, employees living in smaller settlements and those with higher educational levels. The correlates of physical activity among middle-aged employees seem to be domain-specific. Therefore, future studies in this area should consider assessing physical activity in each domain separately.

    Objectives The purpose of the current study was to explore the effects of a mobile health (mHealth) intervention based on the Persuasive System Design (PSD) model on health-related outcomes among office workers. Material and Methods The authors conducted a trial that consisted of a 4-week baseline and an 8-week intervention period by reference to 23 office workers in a private research company. The mHealth application was developed to improve these workers’ daily step count, decrease their sedentary time, and increase their sleep duration in accordance with the PSD model. The app features included at least 1 principal factor from each of the 4 main categories of the PSD model (primary task support, dialogue support, system credibility support, and social support). The objective health-related variables were measured using a smartwatch (Fitbit Luxe) that was synchronized with the application using the Fitbit Web Application Programming Interface. Subjects used the app, which included self-monitoring, personalized messages, education, and a competition system for users, during the intervention period. Results Sedentary time exhibited a significant decrease (a median reduction of 14 min/day, p < 0.05) during the intervention period. No significant differences in daily step count and sleep duration were observed between the baseline and intervention periods. Conclusions This study suggests that the mHealth intervention based on the PSD model was useful for reducing sedentary time among office workers. Given that many previous studies on this topic have not been based on any theories, future studies should investigate the impact of structured selection behavior change theories on health-related outcomes among office workers.

    Opis:
    Objectives To prospectively investigate if the risk of chronic neck/shoulder pain is associated with work stress and job control, and to assess if physical exercise modifies these associations. Material and Methods The study population comprised 29 496 vocationally active women and men in the Norwegian Nord-Trøndelag Health Study (HUNT Study) without chronic pain at baseline in 1984–1986. Chronic neck/shoulder pain was assessed during a follow-up in 1995–1997. A generalized linear model (Poisson regression) was used to calculate adjusted relative risks (RRs). Results Work stress was dosedependently associated with the risk of neck/shoulder pain (p trend < 0.001 in both sexes). The women and men who perceived their work as stressful “almost all the time” had multi-adjusted RRs = 1.27 (95% confidence interval (CI): 1.1–1.47) and 1.71 (95% CI: 1.46–2), respectively, referencing those with no stressful work. Work stress interacted with sex (p < 0.001). Poor job control was not associated with the risk of neck/shoulder pain among the women (RR = 1.04, 95% CI: 0.92–1.19) nor the men (RR = 1.09, 95% CI: 0.95–1.26). Combined analyses showed an inverse dose-dependent association between hours of physical exercise/week and the risk of neck/shoulder pain in the men with no stressful work (p trend = 0.05) and among the men who perceived their work as “rarely stressful” (p trend < 0.02). This effect was not statistically significant among the women or among men with more frequent exposure to work stress. Conclusions Work stress is an independent predictor of chronic neck/shoulder pain and the effect is stronger in men than in women. Physical exercise does not substantially reduce the risk among the persons with frequent exposure to work stress.

    Opis:
    Objectives Following heat illness, a return to activity may require passing a heat tolerance test (HTT). However, there are several logistical limitations to the widespread use of the HTT. Thus, it would be advantageous to develop a test that could be conducted in a thermoneutral (~22°C) environment to predict heat tolerance status. The purpose of the current study was to determine the sensitivity and specificity of using the criteria of a heart rate (HR) ≥130 bpm following 30 min of thermoneutral exercise in detecting heat-intolerant and heat-tolerant individuals. Material and Methods Sixty-five subjects visited the lab on 3 separate days. The first visit consisted of completing a maximal oxygen uptake (VO2 max) test to assess cardiovascular fitness. For lab visits 2 and 3, subjects randomly completed a 2-hour walking treadmill test in either a hot (40°C, 40% relative humidity [RH]) or thermoneutral (22°C, 40% RH) environment. Results Forty-eight subjects were classified as heat-intolerant and seventeen subjects as heat-tolerant. Using the criterion of a HR ≥130 bpm at 30 min of exercise in the thermoneutral environment, specificity (54%) and sensitivity (100%) of passing the HTT was calculated. Secondary analysis using multiple regression revealed 3 significant variables for predicting ending HR during the HTT. They were: 1) absolute VO2 max (l/min), 2) age, and 3) HR at 30 min of exercise during thermoneutral exercise. Conclusions Exercise in a thermoneutral environment had a positive predictive value of 100%, thus, if a subject has a HR ≥130 bpm at 30 min of exercise in a thermoneutral environment, they are very likely to fail a subsequent 2-hour HTT in the heat and be classified as heat-intolerant. Therefore, prior screening has the potential to save time and money, along with providing safety to a heat-intolerant subject.

    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

    Introduction This study evaluated the effect of a 12-month physical exercise intervention accompanied by a 12-month followup evaluating stress symptoms (SS), mental resources (MR) and cardiorespiratory fitness (CRF) in healthy, working adults. We hypothesized that the stress symptoms would decrease and mental resources would increase during the intervention and that these results are associated with changes in CRF. Material and methods The study group included healthy adults (N = 371). Three hundred thirty eight participants (212 women, 126 men) were allocated in the exercise group and 33 in the control group (17 women and 16 men). For the analysis, the exercise group was divided into subgroups according to the baseline SS and MR. Stress symptoms and MR were measured using the Occupational Stress Questionnaire. Results During the 12-month exercise intervention, SS decreased by 16% (p < 0.0001), MR increased by 8% (p < 0.0001) and CRF increased by 7% (p < 0.0001) in the exercise group, while no changes occurred in the control group (ANCOVA, p < 0.01). In the exercise group, the results (SS, MR, and CRF) remained improved during the follow-up. There was a positive correlation between the change in SS and the change in CRF (r = 0.19, p < 0.01). In the subgroup having the highest SS at baseline, SS during the intervention decreased most (26%) (ANCOVA, p < 0.0001). Conclusions One year physical exercise intervention improved mental well-being among working adults and this was associated with an improvement in cardiorespiratory fitness. The positive changes remained after the 12-month follow-up.

    Objectives This study aimed to investigate the prevalence of work-related musculoskeletal disorders (WMSD) in nurses, and to explore the association of work style and physical exercise with WMSD in this professional group. Material and Methods In this study, a cross-sectional survey design was applied. A questionnaire survey was conducted on 692 nurses in 5 municipal hospitals, in the period August–October 2015. The survey included personal information, lifestyle, physical exercise and symptoms of WMSD. Chi² test and logistic regression were used to identify the risk factors of WMSD. Results The prevalence of WMSD was 84% in all parts of the body in the previous year, with the highest prevalence in the neck (68.2%), followed by waist (67.6%) and shoulder (54.6%). Both univariate and multivariate analyses showed that physical exercise, night shifts and staying up late were associated with WMSD in nurses. The lack of exercise, night shifts and a tendency to stay up significantly increased the risk of WMSD (p < 0.05). Conclusions The prevalence of musculoskeletal disorders among the municipal hospital nursing staff is high. An elevated risk of WMSD is observed in nurses who do not do exercises, work shifts and stay up late. Int J Occup Med Environ Health. 2019;32(1):15–24

    Objectives To cross-validate the existing peak rate of oxygen consumption (VO₂peak) prediction equations in Dutch law enforcement officers and to determine whether these prediction equations can be used to predict VO₂ₚₑₐₖ for groups and in a single individual. A further objective was to report normative absolute and relative VO₂ₚₑₐₖ values of a sample of law enforcement officers in the Netherlands. Material and Methods The peak rate of oxygen consumption (ml×kg⁻¹×min⁻¹) was measured using a maximal incremental bicycle test in 1530 subjects, including 1068 male and 461 female police officers. Validity of the prediction equations for groups was assessed by comparing predicted VO₂ₚₑₐₖ with measured VO₂ₚₑₐₖ using paired t-tests. For individual differences limits of agreement (LoA) were calculated. Equations were considered valid for individuals when the difference between measured and predicted VO₂ₚₑₐₖ did not exceed ±1 metabolic equivalent (MET) in 95% of individuals. Results None of the equations met the validity criterion of 95% of individuals having ±1 MET difference or less than the measured value. Limits of agreement (LoAs) were large in all predictions. At the individual level, none of the equations were valid predictors of VO₂ₚₑₐₖ (ml×kg⁻¹×min⁻¹). Normative values for Dutch law enforcement officers were presented. Conclusions Substantial differences between measured and predicted VO₂ₚₑₐₖ (ml×kg⁻¹×min⁻¹) were found. Most tested equations were invalid predictors of VO₂ₚₑₐₖ at group level and all were invalid at individual levels.
