OBJECTIVE ASSESSMENT OF THE BREATHE-RIGHT DEVICE DURING EXERCISE IN ADULT MALES

In order to improve nasal breathing during competition, many athletes recently have been wearing a spring-loaded, external nasal dilator ref erred to as the Breathe-Right device (BRD). Although there are many su bjective claims that this device improves breathing during exercise, t here are currently no controlled studies documenting its efficacy. To determine objectively whether the device improves the nasal airway, 20 subjects (10 Caucasian and 10 African-American) were studied during r est and after 15 minutes of exercise using anterior rhinomanometry and acoustic rhinometry to measure changes in airway resistance and minim al cross-sectional area respectively. We found that the BRD exerts its main effect in the region of the nasal valve improving the airway an overall 21% in our group of subjects. This anatomic improvement in nas al airway resulted in an overall 27% reduction in nasal resistance in the Caucasian group. However, in the African-American group, a wider r ange of resistance changes was observed with application of the BRD wi th significant improvement in nasal resistance in some subjects but pa radoxical worsening in others. In the African-American group as a whol e, no significant change in nasal resistance occured with application of the BRD. These measured differences are likely due to variations in nasal anatomy that exist not only between races but also between indi viduals within a given race. In addition, this study confirms the well known decongestant effects of exercise providing anatomic data with a coustic rhinometry not previously documented in the literature. Overal l improvement in nasal airway seen with application of the BRD occured independent of these exercise-related decongestant effects.
