There is a concern to use masks during physical activities when exercising and working. Wearing activity will pose risk physiological changes in the body human heat strain by principle of mask can block respiratory tract. This study aims determine how much quantitatively qualitatively using different types medical masks, cloths N95. were 10 respondents as sample this study. The results obtained...
Introduction: The traditional view that neonates are not capable of perceiving pain has been refuted and there is now no doubt those neonates feel pain. Although babies cannot express their pain as older children, but capable to show in response the pain a set of measures as observable behavioral responses. The aim of this study was to determine Effect of foot reflexology on physiologic index o...
Introduction: This study was designed with the main purpose of examining the compatibility of the two indicators of wet bulb globe temperature (WBGT) and predicted thermal strain (PHS) in assessing the environmental conditions and the heat load imposed on the subjects. Method: In this cross-sectional study, 163 bakers were included in the study. Thermal stress was determined using the WBGT and...
OBJECTIVE Explosive ordnance disposal (EOD) often requires technicians to wear multiple protective garments in challenging environmental conditions. The accumulative effect of increased metabolic cost coupled with decreased heat dissipation associated with these garments predisposes technicians to high levels of physiological strain. It has been proposed that a perceptual strain index (PeSI) us...
responses of twenty chickpea genotypes to drought stress were evaluated in the farm of college of agricultutre, razi university, kermanshah, iran in 2006-2007. the experiment was carried out in randomized complete block design with three replications under two water stress and non-stress conditions. the results showed significant differences among the genotypes for most of the traits. maximum y...
در این مطالعه پارامترهای قلبی - عروقی راه رفتن با سه نوع عصا (اگزیلاری، لبو، واکر) در ده بیمار با ضایعه نخاع کمری مقایسه گردید و سه شاخص (pct) physiological cost index، سرعت راه رفتن و (rpe) rate of perceived exertionاندازه گیری شد. همچنین تاثیر وضعیت تعادل، نوع ضایعه و میزان استفاده از عصا بر pcl، سرعت راه رفتن و rpe مورد بررسی قرار گرفت . بیماران با هر یک از سه نوع عصا بر روی مسیری به شکل هشت...
This study consists of assessments of the thermal environment and physiological strain in tasks associated with airport, construction, and metal jobs. The number of male and female participants was 108. Environmental heat stress was evaluated with the WBGT index. Physiological strain was evaluated by the relative cardiovascular load (%CVL) based on the measurements of heart rate. Also the incre...
The glycemic index (GI) is a physiological assessment of a food’s carbohydrate content through its effect on postprandial blood glucose concentrations. Evidence from trials and observational studies suggests that this physiological classification may have relevance to those chronic Western diseases associated with overconsumption and inactivity leading to central obesity and insulin resistance....
background : necessity of evaluating heat stress in the workplace, require validation of indices and selection optimal index. the present study aimed to assess the precision and validity of some heat stress indices and select the optimum index for using in heavy work activities in hot and dry climates. methods: it carried out on 184 workers from 40 brick kilns workshops in the city of qom, cent...
