Effects of surgical correction of nasal obstruction on running economy.
Article in European journal of applied physiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aimed to investigate the effects of surgical correction of nasal obstruction on aerobic performance parameters in athletes with nasal obstruction. Specifically, we examined changes in running economy (RE), oxygen uptake (VO₂), and ventilatory responses following nasal surgery. Although previous studies have explored the effects of nasal airflow on exercise, this is the first to directly assess the impact of surgical intervention on physiological determinants of athletic performance.
methodsEleven male athletes diagnosed with nasal obstruction (experimental group, EG) and 11 matched athletes without nasal issues (control group, CG) participated. Nasal patency was evaluated using acoustic rhinometry, while subjective symptoms were assessed using the Nasal Obstruction Symptom Evaluation (NOSE) scale and Epworth Sleepiness Scale (ESS). All participants performed an incremental treadmill test to assess running economy, gas exchange, and ventilatory parameters both before and 2-3 months after surgery.
resultsPost-surgery, the EG showed significant improvements in nasal patency and sleep quality, with NOSE scores decreasing from 61.36 ± 15.83 to 8.64 ± 10.27 and ESS scores from 5.09 ± 2.12 to 3.09 ± 1.76. Additionally, oxygen consumption decreased, and ventilation volume increased during the submaximal treadmill stages in the EG. A statistically significant Group × Time interaction was found for RE (p = .005), indicating greater improvements in oxygen cost in the surgical group.
conclusionSurgical correction of nasal obstruction significantly improves running economy and ventilatory efficiency by reducing upper airway resistance and respiratory muscle workload. These adaptations may enhance aerobic performance in athletes with nasal obstruction.
