ABSTRACT
Bronco constriction is induced by exercise. There are several studies on pulmonary function in athletes during exercise, but there is not a specific study on basketball athletes. The objective of this study was to evaluate the pulmonary function changes during basketball in professional players. This study was a before and after study on spirometric parameters during basketball play. Respiratory function was assessed in participants before and 6 to 9 minutes after exercise with a spirolab 2. The study was conducted in three groups, National team of basketball as professional athletes, university team of basketball as semi-professional athletes and medical students as non-athletes group. Thirty five professional athletes, 12 semi-professional athletes and 34 non-athletes participated in this study. Overall, forced vital capacity [FVC] was significantly decreased after exercise [p=0.000], but this change was significant in professional athletes [p=0.05]. Although forced expiratory volume in 1 second [FEV1] didn't have significant changes after exercise, there was a significant reduction in this parameter among professional athletes. There were not any significant changes in other spirometric parameters. The reduction in FVC and FEV1 were not more than 6%. We concluded that changes in pulmonary function parameters in professional basketball players were more than semi-professional and non-athletes people
