Abstract
- High concentrations of PM2.5 will not only lead to a decline in lung function, but also increase the incidence and mortality of respiratory diseases, and even affect people who engage in outdoor physical exercise. Long-term exposure to high concentrations of PM2.5 will have an impact on athletes' health and sports performance. By taking sprinters from a track and field team of a university in Shanxi as the research object and analyzing the changes of atmospheric PM2.5 on athletes' lung function indicators before and after training under different loads, this study aims to explore the short-term health effects of atmospheric fine particles on athletes' lung function under different loads. The results of testing athletes' lung function show that the athletes do not have abnormal pulmonary ventilation and weakened small airway function under medium and low load training, while athletes might have weakened small airway function under heavy load training. Under different loads, PM2.5 has a certain short-term negative effect and lag in the impact of various indicators reflecting the large and small airway functions of athletes, especially under heavy load. The impact of functional indicators is more obvious. This article provides a basis for reasonable systematic training of athletes in the environment of high atmospheric pollution in North China.
