background: in order to fit the job physiologically to the worker, understanding of acceptable work load is very important. this study was conducted to estimate energy expenditure during the work and associated factors among male workers of a steel industry. methods: in this cross-sectional study, 100 male workers employed in foolad payeh fars with dynamic job participated voluntarily. data col...
OBJECTIVE For many people, most of the working day is spent sitting in front of a computer screen. Approaches for obesity treatment and prevention are being sought to increase workplace physical activity because low levels of physical activity are associated with obesity. Our hypothesis was that a vertical workstation that allows an obese individual to work while walking would be associated wit...
considerable consequence of households’ consumption expenditure changes is on energy using in agricultural sector and in other economical sectors. the main objective of this paper was to study of consequences increasing rural and urban households expenditures on changing of energy using in agricultural sector and on producing of environmental pollutants in khorasan razavi province. for this pur...
N EW understanding of the natural history of heart disease and better methods of treatment are reducing the aura of fear traditionally surrounding the cardiac patient. At the same time, modern technology is steadily lowering the physical demands of factory work, so that it is now evident that a majority of urban patients with heart disease can work safely.1 The physician, who is increasingly ca...
conclusions decreasing barriers to physical activity among the elderly causes physical activities to increase; therefore, energy expenditure is increased. decreasing social and environmental problems for the elderly is effective in increasing physical activity and energy expenditure. results the average age among the study population was 67.6 ± 6.8 years median, and the interquartile range (iqr...
[Purpose] The purpose of this study was to investigate the effects of energy expenditure rate on work productivity performance at different levels of production standard time. [Subjects and Methods] Twenty industrial workers performed repetitive tasks at three different levels of production standard time, normal, hard, and very hard. Work productivity and energy expenditure rate were recorded d...
In order to find out the work load of matrons under shift work in a special nursing home for the elderly (SNH), six healthy female matrons volunteered to participate in the present study. For each subject, care working time, heart rate, walking steps, estimated energy expenditure and working time in different postures were determined during day shift work (540 min) and night shift work (960 min...
Eating at a time when the internal circadian clock promotes sleep is a novel risk factor for weight gain and obesity, yet little is known about mechanisms by which circadian misalignment leads to metabolic dysregulation in humans. We studied 14 adults in a 6-d inpatient simulated shiftwork protocol and quantified changes in energy expenditure, macronutrient utilization, appetitive hormones, sle...
Abstract: Parenteral Nutrition Formulae in Iranian Generic Project were studied in 31 patients hospitalized in ten major general hospitals in Tehran and Shiraz. Estimated theoretical energy (Calculated Energy Value or CEE) using Harris- Benedict equations and applying the Cerra stress factor was compared with the amount of energy estimated via indirect calorimetric technique (Measured Energy ...
