purpose: military personnel are expected to maintain the highest possible level of physical fitness to do their duties. several factors including body composition and body mass index affect the level of their physical preparedness. the current study was designed to investigate the effect of body composition and body mass index in the level of physical preparedness of iranian military pe...
Introduction: Firefighting is amongst jobs that require high physical strength and high aerobic capacity. These are required because of the nature and the physical demands of the job. The maximum aerobic capacities of firefighters were investigated using the step test. Methods: This cross-sectional descriptive-analytical study was conducted on 73 firefighters. At first, demographic informati...
In order to investigate the effect of vermicompost on physical and chemical properties of soil, an experiment was carried out in split plot based on complete randomized block design in three replications in Sari Agricultural Sciences and Natural Resources University. The physical and chemical properties of soil included bulk density, particle density, total porosity, water holding capacity, fie...

Caves are an extreme environment for humans because of the high humidity, mud, darkness, and slippery conditions. Explorations can last many hours or even days, and require extensive climbing and ropework. Very little is known about the physical capacity of cavers and their energy expenditure (EE) during caving. The physical capacity of 17 (7 females) expert cavers (age 43.9 ± 7.3 years) was as...
Background and Aim: Fitting the human to the job is one of the most important goals of ergonomics so that a person can work in a work environment commensurate with his energy. Diet and nutrition are among the most important factors affecting the physical and cognitive function of individuals. Therefore, estimating the amount of energy intake by people and improving nutrition services will be ef...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
Introduction: Measurement of Maximum aerobic capacity (VO2-max) is important in physiologically fitting the workers to the job. The objective of this study was to investigate the effect of anthropometric and demographic factors on physical work capacity. Methods: Methods: In this study 60 students of Ahwaz University of Medical Sciences were selected voluntarily. A checklist consisted of two s...
