The now commonplace wearing of external nasal splints by sportsmen and athletes has never been scientifically evaluated. The present study looks into the effect of isotonic exercise on nasal resistance, and examines whether this effect is altered by the wearing of an external nasal splint.
Twenty subjects not suffering from rhinitis were tested. Nasal resistance measurements were recorded using an anterior rhinomanometer before and after isotonic exercise with and without an external nasal splint. Pulse and blood pressure were measured before and after exercise.
Significant changes were observed in pulse (p < 0.001) and both systolic (p < 0.002) and diastolic (p < 0.001) blood pressure in response to exercise. Significant differences were seen in nasal resistance when the splint was applied (p < 0.001) and after exercise (p < 0.003). No significant difference was observed after exercise when the splint was worn (p = 0.167).
External nasal splints decrease nasal resistance at rest but are of little value during isotonic exercise.
运动员佩戴外部鼻夹这一如今常见的做法从未经过科学评估。本研究探讨等张运动对鼻阻力的影响,并检验佩戴外部鼻夹是否会改变这种影响。
对20名未患鼻炎的受试者进行测试。在有和没有外部鼻夹的情况下,使用前鼻测压计记录等张运动前后的鼻阻力测量值。在运动前后测量脉搏和血压。
运动后脉搏(p < 0.001)、收缩压(p < 0.002)和舒张压(p < 0.001)均出现显著变化。佩戴鼻夹时(p < 0.001)和运动后(p < 0.003)鼻阻力存在显著差异。运动时佩戴鼻夹后未观察到显著差异(p = 0.167)。
外部鼻夹在静息状态下可降低鼻阻力,但在等张运动期间作用不大。
