Introduction: Many studies have been done that support the issue related jobs such as firefighting and rescue because of its nature has a lot of stressors that directly address the mental physical condition, performance and affect your quality of life for people. Exposure to hot and humid environmental conditions and heat through sweating and evaporation of sweat, the workload will increase the cardiovascular syste. Consuming oxygen during firefighting duties, about 60 to 80 percent of the maximum aerobic. Despite the myriad dangers of fire in the job, cause 45 percent of deaths during the Caribbean firefighters, sudden heart attack and most important job due to end early cardiovascular disease activity has been reported fire. Therefore, present to intended purpose firefighters survey covered with protective clothing in hot and humid environment on the hypoxic and aerobic capacity firefighters port city of Bushehr were men.
Methodology: For the study, 30 patients aged 10±30 years and firefighters an average weight of 84 kg and 10 men were randomly assigned to three groups, Group (control), Group (uniforms) and Group (operational clothing) Split respectively. Environmental conditions in the laboratory room to monitor temperature and humidity at 25 degrees and 50% humidity for the first group and the second group and the third using a vaporizer to provide heat conditions at 35 ° C and 70% humidity took its effect on Activity dependent variable (SPO2) examined the heart rate and aerobic capacity. In this study, the WFI by 85% on a treadmill exercise protocol was used based on the 85% THR based on age, heart rate and blood oxygen level during the workout control with pulse oximeter and aerobic capacity 3 groups vo2max was measured according to the formula.
Results: Based on the findings in this study the greatest reduction in blood oxygen and aerobic capacity sharpest decline among the three groups. The Group of dress was operating in hot and humid environment.
Discussion: According to the findings of the study on the basis of reduced blood gene structure of aerobic activity has been shown that the type of coverage and on the conditions of the environment and the amount of aerobic capacity of firefighters affect blood spot results shows firefighters at the time of the operations of the different conditions of the environment as if we are facing due to the amount of decrease in the X gene their blood.
