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.

Eligibility Criteria

• Age: 18 Years - 35 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

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.

You may qualify if:

• 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

You may not qualify if:

• Diagnosed with respiratory, cardiovascular, or metabolic disease
• Currently receiving physiotherapy or pulmonary rehabilitation
• Regular use of medication affecting breathing or exercise capacity
• Pregnancy
