비강 통기도 개선이 유산소 운동능력에 미치는 영향

Background and Objective: In previous studies, there were few reports about little relationship between the degree of nasal patency and physical power. However, previous studies failed to consider the parameter of excise and physical performance. This study was therefore designed to evaluate the relationship between nasal patency and parameters of excise (heart rate, respiratory rate, oxygen saturation) and also, athletic performance. Methods and Methods: 21 healthy men fee from nasal pathologic conditions on the physical examination and medical history, were selected for this study. To analyze the relationship between nasal patency and aerobic exercise capacity, time taken to run 1500 meters was measured as athletic performance. Eleven persons (group 1) were applied with nasal decongestant by nasal aerosol and ten persons (group 2) were applied with nasal aerosol with normal saline as the control. Before and after exercise, nasal patency, heart rate, respiratory rate and oxygen saturation was measured in both groups. The relationship between nasal patency and parameter of exercise was evaluated by Visual Analogue Scale (VAS). Results: Before athletic exercise, nasal patency significantly improved with nasal spray in group 1. But after exercise, we couldn’t find any statistically significant difference between group 1 and group 2, and also couldn't find any relationship between increase in the feeling of exercise capacity and athletic performance. Conclusions: The improvement of nasal patency by applying a topical nasal decongestant had no significant effect on aerobic exercise capacity. This suggests that improvement of nasal patency by exercise masked the effect of the topical nasal decongestant on nasal patency. (J Clinical Otolaryngol 2009;20:34–39)
