The task of hygiene, apart from sanitation of the conditions of the external medium, is to work out measures of active influence on the organism helping to increase work capacity and speed up rehabilitation processes after work. In this connection, we have conducted observations over the effect of artificially ionised air of a negative charge sign on the physical work capacity of healthy people...

Background: To establish a balance between work (physical exercise) and human, the aerobic capacity (VO2max) could be used as a measure. Assessing heart rate in association to physiological symptoms is the most commonly used tools for the assessment of fatigue during physical exercise. This study aimed to investigate the association between the aerobic capacity and the heart rate of workers fro...

INTRODUCTION This study has been performed to determine the influence of rotating shift work on physical working capacity of Tunisian nurses and to design recommendations to managers so that they implement effective preventive measures. METHODS It is a cross-sectional design using a standardized questionnaire and many physical capacity tests on a representative sample of 1181 nurses and nursi...

OBJECTIVE This study is an interventional evaluation of a post-offer employment testing. The study is designed to determine if shoulder injury rates are lowered when employees are placed at jobs they demonstrate the physical ability to perform. METHODS A physical capacity evaluation based testing protocol was utilized to determine if each new employee had the physical work capacity to perform...

BACKGROUND Decreases in functional ability due to aging can impair work capacity and productivity among older workers. OBJECTIVE This study compares the sociodemographics, health conditions, and physical functioning abilities of young and old workers as well as correlates of physical functioning capacity with the work ability index (WAI). METHOD This exploratory, cross-sectional study exami...

physical modeling for study of deep foundations can be performed in simple chambers (1g), calibration chambers (cc), and centrifuge apparatus (ng). these common apparatus face certain limitations and difficulties. recently, frustum confining vessels (fcv) have been evolved for physical modeling of deep foundations and penetrometers. shaped as the frustum of a cone, this device applies steady pr...
