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:
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:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Athletes Undergoing Septoplasty (EG) | Experimental | This arm included male athletes diagnosed with nasal obstruction who underwent surgical correction via septoplasty. Participants were evaluated before and approximately 2-3 months after surgery. Assessments included acoustic rhinometry to measure nasal cavity cross-sectional areas and volumes, the Epworth Sleepiness Scale (ESS), and the Nasal Obstruction Symptom Evaluation (NOSE) scale. Aerobic performance parameters such as running economy, oxygen consumption, and ventilation volume were measured using an incremental treadmill test and respiratory gas analysis. |
|
| Control Group | No Intervention | Male athletes without nasal obstruction, matched by age and training level with the experimental group. They did not receive any intervention but underwent the same aerobic performance testing protocol at the same time points for comparison. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Surgical correction of nasal obstruction | Procedure | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Running Economy (ml/kg/min) | Running economy was assessed via an incremental treadmill test by measuring steady-state oxygen consumption (VOâ‚‚) at submaximal running speeds (e.g., 8, 10, 12 km/h). Improvement in running economy is defined by a decrease in VOâ‚‚ at the same speed, indicating greater efficiency. | Baseline and 2-3 months post-surgery |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Oxygen Consumption (VOâ‚‚ max and submax VOâ‚‚) | Peak and submaximal oxygen consumption were evaluated using gas exchange analysis during a graded treadmill test. Reduced submaximal VOâ‚‚ values are indicative of improved aerobic performance. | Baseline and 2-3 months post-surgery |
| Change in Ventilation |

Participants were assigned to one of two parallel groups: an experimental group consisting of athletes with nasal obstruction undergoing septoplasty, and a control group of matched athletes without nasal obstruction who did not receive any intervention. Both groups underwent the same aerobic performance evaluations at baseline and at follow-up (2-3 months).

This study was conducted without masking. Participants and investigators were aware of group assignments due to the nature of the intervention (surgical septoplasty). Outcome assessments (aerobic performance tests and symptom questionnaires) were conducted using objective measures and standardized procedures to minimize bias.

Ventilatory volume was measured during each stage of the treadmill test. Increases in ventilation at submaximal intensities suggest improved airway function and respiratory efficiency. |
