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.
Aged between 18-35 years
Healthy individuals with no known systemic, neurological, or musculoskeletal disorders
Nijmegen Questionnaire score >23 (indicative of dysfunctional breathing)
Voluntary participation with informed consent
Diagnosed with respiratory, cardiovascular, or metabolic disease
Currently receiving physiotherapy or pulmonary rehabilitation
Regular use of medication affecting breathing or exercise capacity
Pregnancy
The study population will consist of healthy adults aged 18-35 years with no known systemic, neurological, or musculoskeletal conditions. Participants will be screened using the Nijmegen Questionnaire to identify symptoms of dysfunctional breathing.
