Background and Objectives: One of the most important aspects of ergonomics is physiologic balance between human characteristics and their jobs. This study aimed to investigate the physiological characteristics of janitor, safety guard and facility workers of a work organization and determine their physiological fit.
Methods: A total of 70 staff were evaluated using Queen's college step test, N20 body composition analyzer, SECA scale, RS800CX Polar pacemaker. Descriptive statistics and analytical tests including ANOVA and Pearson correlation were used. The data was analyzed using SPSS 20.
Results: Body Mass Index (BMI) and fat percentage (Fat%) of employees were beyond the optimal range, but Waist to Hip Ratio (WHR) were in the range. Also, the average Maximum Volume of Oxygen consumption (VO2max) were 42/1±62/33 mL/kg/min and the average of working capacity (maximum Physical Work Capacity: PWCmax) were 16/63±4/46 kcal/min.
Conclusion: The results indicated that the level of some physical characteristics is inappropriate, physical fitness is poor and individual capabilities and job requirements are not in balance. Using standardized recruitment tests, providing the possibility of sports activities (by organizations) and finding integrated indicators that simultaneously take into account the physical, mental, social and environmental capabilities of individuals to determine work capacity (by researchers), can be facilitating steps to establish an ergonomic balance in the workplace.
