A new study led by ISGlobal and published in Environment International has analysed the health effects of physical activity in the presence of traffic related air pollution (TRAP). The study concludes that exposure to high levels of air pollution before and during the physical activity could reduce the health benefits of the latter.
The study is part of the EXPOsOMICS European Project, and has been performed in Barcelona by following 30 healthy adults during four days in different air pollution settings. The results show that the volunteers displayed an increase in respiratory function that lasted for several hours after the physical activity, even in highly polluted environments. However, exposure to high levels of air pollution attenuated the respiratory gains associated to exercise. In particular, the participants experienced a decrease in both the lower and upper respiratory tract low, regardless of the level of physical activity they had practiced.
The study suggests that physical activity reduces the negative effects of some particulate matter (PM2,5, PM10 and PMcoarse) on the respiratory tract. In addition, previous exposure also influenced respiratory function among the participants.
