Brief summary

This observational study aims to investigate the relationship between dysfunctional breathing and physical fitness parameters in healthy adults aged 18-35. Participants will be evaluated using the Nijmegen Questionnaire to assess dysfunctional breathing symptoms, and their physical fitness will be measured using the ALPHA-FIT Test Battery. Respiratory muscle strength and pulmonary function will also be assessed. The findings may help healthcare professionals better understand dysfunctional breathing and develop targeted treatment programs.

Detailed description

Dysfunctional breathing (DB) is characterized by chronic alterations in the respiratory cycle, often leading to symptoms such as dyspnea, chest tightness, and hyperventilation. Despite its prevalence, DB is frequently underdiagnosed and mismanaged due to limited awareness among healthcare professionals. This cross-sectional study aims to evaluate the relationship between DB symptoms and physical fitness in healthy young adults. A total of 38 participants diagnosed with DB will be assessed at Istinye University using the Nijmegen Questionnaire, ALPHA-FIT Test Battery, spirometry, and measurements of maximum inspiratory (MIP) and expiratory (MEP) mouth pressures. Data on sociodemographic characteristics will also be collected. The results of this study are expected to support clinicians in the accurate identification of DB and provide insight for the development of personalized rehabilitation strategies that improve physical fitness and respiratory health.
