Boggs, G. W., Ward, J. R., & Stavrianeas, S. (2003). Effects of an external nasal dilator on aerobic performance among college-age women. Medicine and Science in Sports and Exercise, 35(5), Supplement abstract 2069.

This study examined the effect of an external nasal dilator on both sedentary and aerobically trained females using lactate threshold as a measure of aerobic performance. Sedentary (N = 9) and aerobically-trained (N = 8) female college students performed two incremental cycle ergometer tests. A nasal dilator strip was worn on one of the tests.

No significant differences were found in lactate threshold for the with- and without-nasal dilator conditions.

Implication. Nasal dilators have no effect on aerobic performance as represented by lactate threshold.
