Investigating the Maximum Aerobic Capacity of Firefighters in Sabzevar using the Step Test

Background: Firefighting is one of the most dangerous occupations which needs high energy and aerobic capacity. This research was carried out to determine the maximum aerobic capacity and its related factors using the step test among firefighters of Sabzevar city.   Methods: This descriptive-analytical study was conducted on ۵۵ firefighters working in operating sections in five stations in Sabzevar city. Demographic data were collected by a questionnaire, aerobic capacity was measured by using the step test (Taxor and Shahnavaz method), and the results of the test and questionnaire were analyzed by Pearson test and t-test using SPSS software (version ۱۹).   Results: The average of maximum oxygen consumption in the participants was ۲.۹۳±۰.۲۵۳ liters/min. The maximum aerobic capacity in the participants was in the middle category based on the standard values of maximum aerobic capacity in the age groups of ۲۰-۲۹, ۳۰-۳۹, and ۴۰-۴۹. Also, maximum aerobic capacity was significantly associated with age group, height, weight, exercise, and BMI (p <۰.۰۱). However, there was no significant relation between maximum aerobic capacity and marital status, work experience, second job, education, and smoking (P>۰.۰۵).   Conclusion: The average maximum aerobic capacity was higher than other occupational groups but lower than the mean of other firefighters. Therefore, it is recommended to increase their aerobic capacity with a regular exercise program, physical fitness, and weight control; and pre-employment examinations should be performed more carefully to ensure their physical fitness is commensurate with the job.
