Investigating the Physiological Fit of Janitor, Safety Guard and Facility Workers with Their Jobs

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

seventy staff were evaluated using Queen's collage step test, N20 body composition analyzer, SECA scale, RS800CX Polar pacemaker. Descriptive statistics and analytical tests including ANOVA and Pearson correlation were used. SPSS software version 20 used to analyze the data.

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.

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. It is recommended to use standard recruitment tests, providing the possibility of physical activities (organizations). Also, for establishing ergonomic balance should find a physical-psychological-social-environmental index to determine the exact work capacity of employees (researchers).
