Workers in physically demanding occupations require work breaks to recover from exertion. In a laboratory setting, we investigated the impact of ergometer cycling for 7 h in two conditions with an identical total break time but with two different activity–rest schedules. We hypothesised that more frequent but shorter breaks lead to less psychophysical strain and its effects than do less frequent but longer breaks, particularly for older workers. Twenty-nine participants representing three… Expand
Assessment of physical strain in younger and older subjects using heart rate and scalings of perceived exertion
It is suggested that workers can, independent of age, perform physical work all day as long as they work at subjectively equal, moderate intensities. Expand
The impact of work rest scheduling for prolonged standing activity
It was found that prolonged standing affect the muscle fatigue and discomfort especially lower extremities such as foot ankle, lower back and leg and different type of work rest scheduling and gender have significant result towards the muscle Fatigue development. Expand
Cycling at varying load: how are experiences of perceived exertion integrated in a single measurement?
A nearly linear relationship between steady presented intensities and session scalings of PE confirmed the validity of the Category partitioning (CP) procedure. Expand
The impact of work rest scheduling on prolonged standing activity in a Malaysian electronic company
In industrial workplace, standing working position is present in most of production processes. The application of work standing activity allows worker to work in higher degrees freedom and puts theExpand
Assessment of Age-Correlated Occupational Strain as a Prerequisite for Age-Appropriate Work Organization
Because of demographic changes in Germany, the average age of the workforce is progressively increasing. In an attempt to reduce pressure on the labor market, Germany recently changed the retirementExpand
Investigating Musculoskeletal Injury Risk: A Field Study on the Influence of Typical Assembly Activities on the Physiological Response of Industrial Workers
Repeated-measures ANOVA and subsequent conducted post-hoc analyses revealed a significant influence of work height on muscle activity of trapezius pars descendens, anterior deltoideus, erector spinae and rectus femoris, and results show that working above shoulder level has significant influence on workload in other body regions.

Psychophysiological factors of adaptation in elite Paralympic sprint runners with visual impairments – a case study
Introduction. The aim of the work was to determine the features of the influence of psychophysiological indices on the result in running for short distances of an elite sportswoman with visualExpand
Comparative Characteristics of Psychophysiological Indicators in the Representatives of Cyclic and Game Sports
IntroductionSport activity makes the most diverse demands on the speed of human thought processes. This is true for working in conditions of time deficit against the background of constantly changingExpand
Methods in Experimental Work Break Research: A Scoping Review
A standard theoretical model for work breaks is needed in order to further increase the comparability of studies in the field of experimental work break research in the future. Expand
Influence of Singing Dancing During a Rest BreakTowards Productivity and Product Quality
The Pencantingan of Batik process includes physic and mental task, art as well as creativity, in order to increase Productivity and Product Quality requires a touch of relaxation. Singing Dancing isExpand


Design of work/rest schedules for computer work based on psychophysiological recovery measures
Abstract Ambulatory assessment of cardiovascular, electrodermal and electromyographic activity was used to monitor different kinds of strain during eight hours of highly demanding computer work underExpand
Effects of activity-rest schedules on physiological strain and spinal load in hospital-based porters
The aim of the study was to assess the impact of an altered activity-rest schedule on physiological and spinal loading in hospital-based porters and to hypothesized that the experimental trial is more effective in promoting recovery from physiological strain and spinal shrinkage than the normal trial. Expand
Evaluation of work-rest schedules with respect to the effects of postural workload in standing work.
It was concluded that the 60-15 schedule should be avoided and an optimal work-rest schedule considering visco-elastic deformation of the spine would probably involve frequent short breaks, whereas longer breaks would seem more effective considering leg swelling. Expand
The Growth of Perceived Exertion During a Prolonged Bicycle Ergometer Test at a Constant Work Load
Several studies have dealt with the problem of how the perception of exertion (PE) grows when the work load increases during an ergometer test. Borg and Dahlstrom (1959, 1960), Borg (1962, 1972)Expand
The increase of perceived exertion, aches and pain in the legs, heart rate and blood lactate during exercise on a bicycle ergometer
The data support the idea that a combination of heart rate and blood lactate is a better predictor of perceived exertion and feelings of aches and pain in the legs, than is each of the single physiological variables taken alone. Expand
Perceived exertion related to heart rate and blood lactate during arm and leg exercise
For exercise of a steady state type with increasing loads the incremental curve for perceived exertion can be predicted from a simple combination of HR and BL, which gives support for the following generalization. Expand
A field study of supplementary rest breaks for data-entry operators
Increases in discomfort of the right forearm, wrist and hand over the course of the work week under the conventional schedule were eliminated under the supplementary schedule, and beneficial effects were obtained without reductions in data-entry performance. Expand
Evaluation of work-rest schedules during operation of a rotary power tiller
Abstract The operation of a power tiller involves walking behind the machine on a tilled or puddle land continuously for hours. Physical efforts required for the operation of the machine combinedExpand
The impact of rest breaks upon accident risk, fatigue and performance: A review
This review's primary objective is to identify research examining the impact of rest breaks uponaccident risk in industrial settings. In the absence of much directly relevant research, the focusExpand
What is the evidence for less shift work tolerance in older workers?
It was deduced that older compared with younger workers have more sleep problems with night shifts, while the opposite is true for morning shifts, and age-specific aspects should be considered in shift work planning. Expand
