Participatory Ergonomics: A Model for the Prevention of Occupational Musculoskeletal Disorders
2009
La ergonomía participativa es una estrategia de intervención sobre los riesgos por carga física en los lugares de trabajo escasamente conocida en España, aunque en otros países se cuenta con numerosas experiencias y evidencias en este campo. Son varias las razones que justifican su interés. En primer lugar, aborda una de las categorías de riesgos laborales que mayor impacto tiene sobre la salud de los trabajadores en la mayoría de países, tanto en términos de incidencia, como de prevalencia o incapacidad. En segundo lugar, el principio básico de la ergonomía participativa es la capacitación de los trabajadores para que participen tanto en la identificación de los riesgos y daños a la salud …
Work Related Musculoskeletal Disorders (WRMSD) in Construction Workers and Main Causes
2017
Construction industry still is characterized with physically demanding work duties despite the ongoing modernization of new technology. Construction work requires physical and psychosocial effort, working in compulsory and awkward postures. WRMSD are the most common health problems among employees in construction. The aim of this study was to determine WRMSD reasons caused by physical load and psychosocial risks at work for painters and tilers in the construction enterprise. Results of the study shows that causes of WRMSD in employed in construction, are not only physical risks at work, but also psychosocial risks, as well as individual attitude towards one’s own health.
Work posture load evaluation in medium size metal processing enterprise in Latvia
2019
Article The aim of this study was to evaluate the exposure of individual workers to ergonomic risk factors associated with upper, lower extremities and trunk WRMSDs and to assess entire body posture for risk of WRMSDs. The company that produces finished metal products (ironing boards) was chosen for the research. Rapid Entire Body Assessment (REBA) was used to assess the entire body posture for risk of WRMSDs. Rapid Upper Limb Assessment (RULA) method was used for ironing boards employees to evaluate exposure of the neck, trunk, arms and legs in relation to physical load. Our study proved that employees are subjected to WRMSDs due to the load on certain body parts during the work: shoulder …
Stress at Work and Physical Load in Professional Sport
2018
Various professional sports have reached a high level of development. Stress at athletes’ work partly characterizes quality of psycho-emotional work environment. Psychological effects caused by stress frequently change into physical effects. At the same time, it should be noted that athletes do not receive adequate attention from the occupational health and safety point of view. The aim of the research was to investigate influence of work stress and physical load on professional volleyball athletes during trainings in comparison with volleyball competitions. The results reveal that the volleyball players are generally exposed to physical load (94%) and 82% - to work stress and other psycho-…
Physical Load Among Construction Workers and Analysis with Objective Ergonomics Research Method
2016
There is growing number of work related musculoskeletal disorders among workers in construction industry. Employees in construction professions admit physical load and discomfort in various body parts after the work. Accordingly to Eurostat statistical data 60 % of total work related diseases are attributed to musculoskeletal disorders in Latvia. The aim of this study was to determine physical load of construction auxiliary workers and bricklayers using objective ergonomics research method HR monitoring and subjective ergonomic risk assessment methods. The research involved full time 8 auxiliary construction workers and 7 bricklayers. Analysis of the heart rate monitoring data proved that o…
Evaluation of occupational physical load during 6-month international crisis management operation
2018
Objectives Generally, operational military duties are associated with a variety of stressors, such as prolonged physical activity (PA). However, limited information is available on the occupational workload or changes in PA during international military operations. Thus, the aim of the study was to investigate the changes in body composition, stress biomarkers, PA, and heart rate (HR) responses of 79 male soldiers during a 6-month international crisis management operation. Material and Methods Measurements were conducted 3 times in South-Lebanon during the operation. Body composition was assessed by the bioelectrical impedance method. Blood samples were analyzed for serum testosterone, sex-…
Effect of Prolonged Military Field Training on Neuromuscular and Hormonal Responses and Shooting Performance in Warfighters
2018
Introduction: Previous studies have shown that military field training (MFT) has effects on warfighters’ hormonal responses, neuromuscular performance, and shooting accuracy. The aim of the present study was to investigate the changes in body composition, upper and lower body strength, serum hormone concentrations of testosterone (TES) and cortisol (COR), insulin-like growth factor-1 (IGF-1), and sex hormone binding globulin (SHBG) and shooting accuracy during prolonged MFT. Methods: Serum hormone concentrations, isometric strength of the upper and lower extremities, and shooting performance were measured four times during the study: before MFT (PRE), after 12 d (MID), at the end of MFT (PO…
Physical Load and Preventive Measures in Metal Manufacturing Industry
2020
In today’s advanced work environment, workers are still exposed to ergonomic risks in the work environment and employees are exposed physically hard work that includes moving loads and frequent repetitive movements at fast pace. For the ergonomic risk analysis and workload assessment, three work operations with the high physical activity were selected: the welder’s workplace, the ironing board sorting line and the ironing board’s packing station. Subjective and objective ergonomics research methods were used. Research results show that employees in selected work operations are exposed to a fast work speed and often, monotonous movements at the sorting line and lifting heavy loads at the iro…
