Introduction: The fire fighting is one of the demanding and hazardous of all occupations so that it is recorded 96% deaths occurred in firefighters who were over 40 years old. Reported high activity of the sympathetic system and heart rates in excess of 95% HR during simulated or live firefighting tasks. The purpose of this study was determining the effect of ageing and overweight on biological motion indexes and cardiovascular risk factors in three group's age firefighters of Mashhad.
Methods: In this study, 195 firefighters from 26 fire stations selected by simple stratified sampling and placed in three groups aged I: 25-34, II: 35-44 and III: 45-54 years. Measuring dimension physical, aerobic power, anaerobic, explosive power, muscular endurance, agility and grip strength as an indicator of biological movement indexes (BMI) and TG; TC; LDL-c; HDL-c; atherogenic index of blood samples was measured as predictive of cardiovascular risk factors. In order to compare variables in three age groups, one-way variance analysis and Bonferroni correction test were used.
Results: Three groups showed a significant difference in biological movement indexes and cardiovascular risk factors (P<0.05). On the other hand, the biological movement indexes and cardiovascular risk factors in age groups 25-34 years have had better conditions than the other two groups.
Conclusion: Finding of this study showed that firefighters of Mashhad with increase of their age are overweight and obese and also their physical health may reduce.
