The aim of this study was to investigate the effect of physical activity on cardiovascular function in polluted air. In this study ten healthy male university students within the age range of 21.12±1.80 were randomly selected. They have taken physical activity tests including (Bruce treadmill test,EKG, blood pressure, heart rate, and percent of oxygen saturation in fresh air (PSI=70) and polluted air (PSI=135). For data analysis, we applied dependent t-test. The findings of this study showed that physical activity in unhealthy polluted air did not affect ST segment. Unhealthy polluted air had significant effect on arterial oxygen saturation in both resting (sig=0.004) and training (sig=0.049) positions. Air pollution did not affect heart rate, systolic and diastolic blood pressure in resting position; however, in training position, its effect was significant on heart rate (sig=0.009) and systolic (sig=0.001) and diastolic blood pressure (sig=0.005). It seems that physical activity in polluted air significantly affects cardiovascular function in young healthy men.
