In the works of Yu.V. Moikin, the system of fatigue, overwork, overstrain creation under local and other types of muscle loads is presented. Fatigue genesis theory advanced and developed by Yu.V. Moikin, is based on the results of physiological reactions at various levels of neuromuscular apparatus study (working muscle, spinal cord segmental apparatus, subcortical nuclei, cerebral cortex). Functional state physiological specificities were investigated, informative dynamometric indicators, dynamometric indicators, as well as fatigue level assessment electromyographic criteria were determined. Yu.V. Moikin and his disciples showed the magnitude of muscle tension important significance, as maximum arbitrary force (MAF) percentage of given muscle or muscle group. Numerous professions of physical labor workers physiological assessment allowed to establish that the number of movements is determinant for dynamic work and retained effort total time - for static work. In accordance with Yu.V. Moikin basic theoretical provisions there was scientifically substantiated and developed recreational activities complex for employees of various types of economic activity.

Introduction: It is important to assess health impact of the entire set of heterogeneous risk factors and identify the key ones in order to develop personalized measures for prevention of non-occupational diseases in workers. Objective: To establish the major risk factors for circulatory and musculoskeletal disorders in employees of a metallurgical enterprise. Materials and methods: We used anonymized data from a special assessment of working conditions and production control of the forging departments of the forging-rod and forging-press shops of a metallurgical enterprise producing titanium alloys for the years 2016–2020. To determine the presence of personal biological and behavioral risk factors for diseases of the circulatory and musculoskeletal systems, we examined anonymized data of the periodic medical check-up conducted in 2020 of 146 male blacksmiths working with hammers and presses. The mean age of the workers was 35.9 ± 8.8 years (range: 21 to 57 years) and their mean length of current employment was 18.9 ± 9.7 years (range: 2 to 41 years). The method of simple and multiple logistic regression was used to build models for predicting the likelihood of a disease; odds ratios were calculated with a 95 % confidence interval. The quality of the models was assessed using the maximum likelihood estimation. Results: We determined the factors allowing prediction of the disease likelihood. The prevalence of circulatory diseases correlated with age, length of employment, and the body mass index, whole-body and hand-arm vibration, noise exposure, high ambient temperature, thermal radiation, and heavy physical work. The prevalence of musculoskeletal diseases, in its turn, had a somewhat weaker statistically significant association with the same risk factors. Models predicting the likelihood of circulatory and musculoskeletal diseases have been built. The best predictive model for circulatory diseases included the combined effect of the body mass index and heavy physical work while that for musculoskeletal disorders – of the body mass index and hand-arm vibration. Conclusion: Multiple logistic regression used to analyze statistical relationships between work-related risk factors and disease prevalence in employees in specific occupations allowed identification of the leading factors contributing the most to the disease development and can be recommended for solving practical problems in occupational medicine.

Introduction. Identification of functional disorders and prenosological conditions of the circulatory system under the conditions of adverse effects of the occupational environment is a necessary link in the development of measures to prevent health disorders in workers. Materials and methods. The study of functional indicators of hemodynamics, endurance and efficiency, functional reserves of the circulatory system, and ECG dispersion mapping using “Cardiovisor-06s” in eighty five male tractor drivers in agricultural production (agricultural machine operators) was carried out. The average age of the surveyed cases was 42.36±1.2 years, the average work experience in the occupation is 19.61±1.26 years. Results. Agricultural machine operators, whose working conditions are characterized by the influence of working environment factors with a prohypertensive effect, have been established to reveal changes in the indicators of the functional state of the circulatory system and a decrease in the adaptive capabilities of the body, indicating the manifestation of borderline states between the norm and pathology. Between the duration of work experience in the occupation and the level of functioning of the circulatory system, a statistically significant correlation was established (r = 0.53) According to ECG dispersion mapping, individual values of the “Myocardium” microalternation index in 14.3% of the examined cases corresponded to a borderline state close to the initial stage of probable pathology . The most pronounced changes, indicating a violation of cardiometabolic processes, were noted in workers over 40 years. The average values of the “Rhithm” index (RI), which characterizes the integral component of heart rate variability, which is a marker of the adaptive capabilities of the body, were in the range of 21–35% for all examined persons (with a normal value of 0–20%), which corresponded to an increased tension of regulatory systems or a borderline state. Increased individual levels of RI were more often recorded in people over 50 years. Limitations on the study are determined by the area of studying the subject of research in one professional cohort of workers. Conclusion. Early detection of prenosological changes in systemic hemodynamics and adaptation of the circulatory system can be one of the tools to identify the risk group of workers who need to develop and implement measures to prevent diseases of the circulatory system.
