The effects of air pollutants on nasal functions of outdoor runners

Nowadays road running is becoming more and more popular in our country. Road running is mostly done under improper conditions. The aim of this study was to investigate the effects of running on nasal response combined with the effects of air pollutants. Twenty road runners were enrolled in the study. All subjects were male and between 20 and 41 years of age. They ran for 60 min on the right side of an avenue in the center of the city. It is in a residential area but has heavy traffic. One week later they were invited to run for 60 min through a running course away from traffic that is located outside the city center. Nasal resistances were measured by active anterior rhinomanometry. Nasal transport time was also measured by saccharin transport method. There was a reduction in nasal resistance, which was statistically significant in city center runners but was not statistically significant in those running outside of the city center after the exercise. Although nasal transport times were statistically shorter in both groups, there were no differences between two groups. Nowadays, everyone is advised to do sports. Due to increase in the number of breaths, the depth of breathing, and the reduction in nasal resistance in outdoor runners during exercise, harmful air pollution particles can easily reach the lower respiratory tract. Exercise is important for our health, but it should be noted that the environment in which we run is as important as doing sports for our health, especially in outdoor runners.
