Summary

This retrospective study aims to evaluate the effect of surgical correction of nasal obstruction on aerobic performance parameters in male athletes aged 20-32 years. The main questions it aims to answer are: * Does nasal obstruction surgery impact running economy and ventilation during exercise? * Does it affect oxygen consumption during submaximal running efforts? Researchers will retrospectively compare male athletes who underwent nasal obstruction surgery (experimental group) to matched athletes without nasal obstruction (control group) to assess changes in respiratory function and exercise performance. Participants were assessed by: * Acoustic rhinometry to measure nasal cavity dimensions. * The Nasal Obstruction Symptom Evaluation (NOSE) scale and Epworth Sleepiness Scale (ESS) to evaluate nasal obstruction symptoms and daytime sleepiness. * Incremental treadmill exercise tests to collect data on gas exchange, oxygen consumption, ventilation, and running economy before and after the surgical intervention (or across a similar time period for the control group).

Conditions

• Nasal Obstruction
• Septoplasty Surgeries
• Athletic Performance

Interventions

Type	Name	Description
PROCEDURE	Surgical correction of nasal obstruction	Surgical intervention to correct anatomical nasal obstruction, specifically septal deviation, performed under general anesthesia. The procedure involved the repositioning and reshaping of the deviated nasal septum to improve nasal airflow. The surgery was conducted by an otolaryngologist with experience in nasal airway procedures. No additional medications or postoperative interventions beyond standard care (e.g., saline irrigation, analgesics) were administered. Postoperative assessments occurred 2-3 months after surgery, including evaluations of nasal patency, sleep quality, and aerobic performance using treadmill-based gas exchange measurements.
