Breathing Exercises and Heart Rate Variability in Healthy Adults
Official title: THE EFFECTS OF DIFFERENT BREATHING EXERCISES ON RESPIRATORY PARAMETERS AND HEART RATE VARIABILITY
Run by Bandırma Onyedi Eylül University · NCT07739238 · Data updated 2026-11-12
This study tests whether diaphragmatic, square, and alternate-nostril breathing can affect respiratory patterns and heart rate variability in healthy adults ages 18–30.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–30 who are not regularly physically active and do not have known respiratory, cardiovascular, renal, neurological, or musculoskeletal disorders.
✕Probably not a fit
Individuals with existing respiratory, cardiovascular, renal conditions, recent surgery, or those who are immobilized or highly trained athletes may receive little or no benefit.

What this trial studies
Participants will perform different breathing exercises to compare how each method affects breathing mechanics and heart rate variability. The study focuses on healthy adults who do not engage in regular physical activity. Interventions include diaphragmatic breathing, square breathing, and alternate-nostril breathing, with outcomes centered on respiratory parameters and heart rate variability. The design appears to be interventional, but phase information is not defined. Location is in Balıkesir, Turkey, with potential consideration of additional sites abroad as specified by the sponsor.
Why it matters
Potential benefit: If successful, these breathing practices could be recommended to improve autonomic balance and respiratory function in appropriate settings.
How similar studies have gone: Previous work has shown that different breathing techniques can influence autonomic function, though findings vary by method and population.
