This study examined the effect of an external nasal dilator strip (ENDS) on three field tests of maximal performance and monitored the rating of perceived breathing effort (RPBE). Thirty male Chinese students (age 15.2 +/- 1.6 yrs) performed three maximal field tests: (a) short-term anaerobic power (SAnP: 40-m sprint); (b) long-term anaerobic power (LAnP: shuttle sprint); and (c) peak aerobic performance (AeP: multistage 20-m shuttle run) under three conditions: ENDS, placebo, and control. Students were randomly placed into 6 groups using a fully counterbalanced single-blind design. No significant differences were seen between conditions in the anaerobic performances measured by SAnP and LAnP. However, the ENDS produced a significant improvement in peak aerobic performance (p = 0.037) compared to the control condition of 3.2% (95% CI= 6.2-0.2; Cohen effect size = 0.2), and also compared to the placebo condition (p = 0.018) of 2.9% (95% CI = 5.1-0.2; Cohen effect size =0.2). The ENDS condition also significantly reduced RPBE during the AeP and LAnP tests by an average of 5.5% and 3.8%, respectively. Wearing an external nasal dilator can significantly reduce breathing effort and improve peak aerobic performance during field tests involving maximal running.

“…A significant difference in VO 2 max when using the END was noted in five studies only, whereby one evaluated male triathletes [17], three studied adolescents of both sexes who regularly practice exercise [5,6,18], and one study was on adult men and women (the study did not describe the training level of the volunteers) [4]. The use of a placebo END was reported in ten studies [5,6,13,18,19,[23][24][25][26][27] and in the others it was compared with the absence of the END [4,10,17,21,22,29,31]. Eight studies evaluated men and women [4,5,13,22,24,26,27,31] and the others only assessed men.…”

Background Numerous studies have shown that the external nasal dilator (END) increases the cross sectional area of the nasal valve, thereby reducing nasal resistance, transnasal inspiratory pressure, stabilizing the lateral nasal vestibule, and preventing its collapse during final inhalation. Objectives Our objective was to carry out a systematic review of the literature and meta-analysis on the effects of the END during physical exercise. Methods After selecting articles in the PubMed, Cochrane Library and EMBASE databases, 624 studies were identified. However, after applying the inclusion and exclusion criteria, 19 articles were considered eligible for review. Results Those studies included in the meta-analysis, the maximal oxygen uptake (VO 2 max.) outcome was assessed in 168 participants in which no statistically significant difference was found, MD (95% CI) = 0.86 [− 0.43, 2.15], p = 0.19, and I 2 = 0%. The heart rate (HR) outcome was assessed in 138 participants in which no statistically significant difference was found, MD (95% CI) = 0.02 [− 3.19, 3.22], p = 0.99, and I 2 = 0%. The rating of perceived exertion (RPE) outcome was assessed in 92 participants in which no statistically significant difference was found, MD (95% CI) = − 0.12 [− 0.52, 0.28], p = 0.56, and I 2 = 27%. Conclusions The external nasal dilator strip showed no improvement in VO 2 max., HR and RPE outcomes in healthy individuals during exercise.
