Introduction. The aim of this study was to estimate maximal aerobic capacity (VO2 max), to determine its associated factors among workers of industrial sector of Iran and to develop a regression equation for subjects’ VO2 max. Methods. In this study, 500 healthy male workers employed in Shiraz industries participated voluntarily. The subjects’ VO2 max was assessed with the ergocycle test according to the Åstrand protocol. Required data was collected with a questionnaire covering demographic details (i.e., age, job tenure, marital status, education, nature of work, shift work, smoking and weekly exercises). Results. The subject’s mean VO2 max was 2.69 ± 0.263 l/min. The results showed that there was an association between VO2 max and age, BMI, hours of exercise and smoking, but there was no association between VO2 max and height, weight, nature of work and working schedule. On the basis of the results, regression equations were developed to estimate VO2 max. Conclusion. Final regression equation developed in this study may be used to estimate VO2 max reliably without the need to use other laboratory instruments for aerobic measurement.
