Since the reform and opening up, the economy has developed rapidly, and the development of sports and health education has been closely related to the national economic development, the research on the scientific training of lung function has become the focus of the research of sports workers. Through comparative analysis of literature and calculating method of pulmonary function definition and lung function index, literature method, questionnaire method and experimental test method were used, the male subjects of a professional track and field training team and non-physical education college in Inner Mongolia area were selected as subjects, the pre -, mid - and post - tests were used to test the function of gas metabolism during the incremental exercise, so that the changes of lung function and energy metabolism were analyzed, and the relationship between the changes of some physiological and gas metabolism indexes during exercise was discussed. In this study, the trend of pulmonary function of athletes in the course of exercise was further clarified, which laid a good foundation for more scientific and rational training.
