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).

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.
Change in Running Economy (ml/kg/min)
Running economy was assessed via an incremental treadmill test by measuring steady-state oxygen consumption (VO₂) at submaximal running speeds (e.g., 8, 10, 12 km/h). Improvement in running economy is defined by a decrease in VO₂ at the same speed, indicating greater efficiency.
Time frame: Baseline and 2-3 months post-surgery
Change in Oxygen Consumption (VO₂ max and submax VO₂)
Peak and submaximal oxygen consumption were evaluated using gas exchange analysis during a graded treadmill test. Reduced submaximal VO₂ values are indicative of improved aerobic performance.
Time frame: Baseline and 2-3 months post-surgery
Change in Ventilation
Ventilatory volume was measured during each stage of the treadmill test. Increases in ventilation at submaximal intensities suggest improved airway function and respiratory efficiency.
Time frame: Baseline and 2-3 months post-surgery
