Estimation of Maximal Aerobic Capacity (VO2-max) and Study of its Associated Factors among Industrial Male Workers in Snandaj city/Kurdistan Province2013

Estimating the maximal aerobic capacity in humans can be used to establish the proportionality between the worker and work physiology. This study was conducted to determine VO2-max and its associated factors among male workers of industrial sector of Sanandaj city. To conduct this study, 200 healthy and non-smoking male workers were randomly selected. Maximal aerobic capacity (VO2-max) was measured by Tuxworth & Shahnavaz method. T test and one way ANOVA test were used to examine the relationship between qualitative variables and VO2max mean and quantitative variables and VO2-max mean, respectively. The stepwise multiple linear regression analysis was used to build the best model. According to results, workers’ maximal aerobic capacity mean was estimated to be 2.92±0/34 Lit/M. The results showed that there was association between VO2-max and weight and marital status while no association was found between VO2-max and height, BMI, age, education level, shift working, job satisfaction, exercise per week and fatigue. Weight and marital status are the factors affecting the maximal aerobic capacity.
