The Effect of Chronic Breathing Exercises on Pulmonary Functions: A Study on Combined Aerobic Exercise and Synchronized Breathing Exercises

November 21, 2025 updated by: Ahmet KURTOĞLU, Bandırma Onyedi Eylül University

Experimental and Quantitative Research Method

In this respect, the aim of this study was to investigate the effects of synchronous breathing exercise and aerobic exercise on pulmonary functions. In the study, three groups including a control group (CG), an aerobic exercise group (AE), and both breathing and aerobic exercise (AE+SB) were compared and analyzed. In the study, the accuracy of the following hypotheses was tried to be investigated. H1a "Synchronous breathing exercise has an impact on respiratory function." H1b "Aerobic exercises have an impact on respiratory function." H1c "Synchronized breathing exercises combined with aerobic exercises have a greater impact on respiratory function."

Experimental: control group
Other: aerobic exercise with synchronized breathing group
This study was ethically approved by the Bandirma Onyedi Eylül University Rectorate Health Sciences Non-Interventional Research Ethics Committee with the meeting decision numbered 2024-1 on 16.01.2024. Within the scope of the study, all participants were informed about the purpose of the study, the reason for the study, and its contribution to the literature. The participants were informed that this study would be conducted on a completely voluntary basis and that they could withdraw from the study at any time. This study was conducted in accordance with the principles set out in the Declaration of Helsinki. In this study, an experimental and quantitative research method including pre-test and post-test measurements will be used and the chronic effect of 8-week breathing exercises on pulmonary functions, heart rate, and peripheral oxygen saturation (SPO2) level will be examined. Participants' pulmonary function and resting heart rate will be measured
