Współczesne badania wskazują na brak pozytywnego wpływu na zdrowie dużych obciążeń fizycznych w pracy zawodowej, zwłaszcza w połączeniu z deficytem aktywności fizycznej rekreacyjnej w czasie wolnym od pracy. Kobiety, ze względu na uwarunkowania fizjologiczne, nie są w stanie wykonywać wszystkich czynności w pracy na równi z mężczyznami. Dotyczy to zwłaszcza prac związanych z wysiłkiem fizycznym i transportem ciężarów oraz wymuszoną pozycją ciała. W przypadku kobiet starszych, oprócz fizjologicznych różnic podyktowanych płcią, dochodzą zmiany funkcjonalne zachodzące w organizmie ludzkim wraz z wiekiem, które również istotnie obniżają możliwość wykonywania pracy fizycznej. Lekceważenie przez pracodawców problemu ciężkiej pracy fizycznej prowadzi do niekorzystnych skutków, zarówno dla pracowników, jak i dla firmy. Nadmierne obciążenie i związane z nim zmęczenie pracownika jest przyczyną gorszej jakości i wydajności pracy oraz zwiększenia absencji chorobowej. Dlatego oczywista wydaje się konieczność dostosowywania stanowisk i warunków pracy do potrzeb pracownic fizycznych w starszym wieku.

Contemporary studies indicate the lack of a positive impact of high physical effort in professional work on health, especially in connection with the deficit of recreational physical activity during leisure time. Women, due to physiological conditions, are not able to perform all activities at work equally with men. This applies in particular to work related to physical effort, transport of weights and forced body position. In the case of older women, apart from the physiological differences dictated by gender, functional changes occurring in the ageing human body, which also significantly reduce the ability to perform physical work, are added. The problem of employers disregarding hard physical labour leads to adverse effects for both them and their companies. Excessive work toad and, associated with it, fatigue of employees result in inferior quality and work efficiency and the increase in sick leave due to ailments and illnesses. Therefore, it seems obvious to adapt the work station and working conditions to the needs of older women that perform physical work.

W badaniach podjęto próbę określenie wpływu rodzaju czynności fizycznej związanej pracą warsztatową na wielkość i strukturę statycznego obciążenia układu mięśniowo szkieletowego człowieka pracą. Na podstawie analizy poklatkowej dokonano analizy zmian posturalnych pracowników. Obciążenie układu mięśniowo szkieletowego pracownika określono metodą OWAS (Ovako Working Posture Analysis System). Stwierdzono, że we wszystkich przeanalizowanych przypadkach pracy fizycznej, pozycje ułożenia poszczególnych elementów ciała były wymuszone, ze względu na charakter wykonywanych czynności. Postawę pozycji ciała pracowników warsztatowych w czasie pracy w zdecydowanej większości można zakwalifikować do pierwszej i drugiej kategorii obciążenia. Stwierdzono, że nie ma konieczności nagłych zmian na stanowisku pracy, lecz należy wziąć pod uwagę ich konieczność w niedalekiej przyszłości. Oszacowane metodą OWAS obciążenie pracą statyczną klasyfikowane jest od średniego do dużego.

In the thesis it was attempted to determine the influence of type of physical job in a workshop on the size and structure of static musculoskeletal load of the employees. Their postural changes were analyzed on the basis of the stopmotion analysis. Musculoskeletal load of the workers was determined with OWAS (Ovako Working Posture Analysis System) method. It was found that the arrangement of individual body parts was forced in every physical job position under the analysis, as a result of the job nature. The workshop employees posture during their work can be classified mostly as first or second load category posture. It was found that there is no necessity of urgent changes concerning the job positions but it must be considered in the near future. The static work load as assessed with OWAS method is medium or high.

Effect of Background Music on Maximum Acceptable Weight of Manual Lifting Tasks

This study used the psychophysical approach to investigate the impact of tempo and volume of background music on the maximum acceptable weight of lift (MAWL), heart rate (HR) and rating of perceived exertion (RPE) of participants engaged in lifting. Ten male college students participated in this study. They lifted a box from the floor, walked 1–2 steps as required, placed the box on a table and walked back twice per minute. The results showed that the tempo of music had a significant effect on both MAWL and HR. Fast tempo background music resulted in higher MAWL and HR values than those resulting from slow tempo music. The effects of both the tempo and volume on the RPE were insignificant. The results of this study suggest fast tempo background music may be used in manual materials handling tasks to increase performance without increasing perceived exertion because of its ergogenic effect on human psychology and physiology.

Effects of Carbon Dioxide Inhalation on Psychomotor and Mental Performance During Exercise and Recovery

On separate days, 6 highly trained participants performed psychomotor tests while breathing for 60 min 3 carbon dioxide (CO2) mixtures (room air, 3% CO2, or 4% CO2) prior to, between, and following two 15- min treadmill exercise bouts (70% VO2max). Each individual was extensively practiced (at least 4 days) before testing began, and both gas conditions and order of tasks were counterbalanced. Results showed physiological reactions and work-related psychomotor effects, but no effects of gas concentration on addition, multiplication, grammatical reasoning, or dynamic postural balance. These findings help define behavioral toxicity levels and support a re-evaluation of existing standards for the maximum allowable concentrations (also emergency and continuous exposure guidance levels) of CO2. This research explored the selection of psychometric instruments of sufficient sensitivity and reliability to detect subtle changes in performance caused by exposure to low levels of environmental stress, in this case differential levels of CO2 in the inspired air.

The first objective of this paper is to compare the observation procedures proposed to characterize physical work. The second objective is to examine the following 3 methodological issues: reliability, observer training, and internal validity. Seventy-two papers were reviewed, 38 of which proposed a new or modified observation grid. The observation variables identified were broken down into 7 categories as follows: posture, exertion, load handled, work environment, use of feet, use of hands, and activities or tasks performed. The review revealed the variability of existing procedures. The examination of methodological issues showed that observation data can be reliable and can present an adequate internal validity. However, little information about the conditions necessary to achieve good reliability was available.

The handling of 2,306 boxes being loaded or unloaded from vans onto or from 4-wheeled trolleys by 31 handlers in a warehouse were characterized. Handling was videotaped and characterized through an analysis grid completed by three trained observers. The following execution parameters were observed: nature of the exertion applied by the upper limbs, plane and direction of the exertion, resulting displacement of the box, grip, use of the lower limbs and the back. Results show that execution parameters used by handlers vary considerably from those usually recommended or studied. For example, symmetric grips were rarely used (4%). The grip was modified during the handling of half the boxes. Significant knee flexion was rarely observed (3% of exertions). Each box was moved by applying an average of . 3.5 different exertions. Exertions were mostly applied in a plane parallel to the shoulders; they were rarely executed in a strict sagittal plane (11%). The implication of these observations are discussed.
