An interventional study of Breathing exercise and Aerobic Exercise in Major Depression, sponsored by Kutahya Health Sciences University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 40 Years. Per ClinicalTrials.gov, last updated 2026-08-05.
Sponsored by Kutahya Health Sciences University · Not applicable, Interventional, and Treatment
This study aims to investigate changes in the levels of biomarkers (IGF-1, FGF2, and EGF) involved in neuron development in patients diagnosed with major depression through the effects of breathing exercises and aerobic exercise, as well as to examine the levels of biomarkers (TNF-α, IL-6, and IL-1) and oxidative stress (TAS, TOS, MDA, and F2-isoprostane) that are thought to play a role in the pathophysiology of depression.

Exclusion Criteria:
Those included in the experimental group continued diaphragmatic breathing exercises every day for three weeks and walking exercises at least three days a week.
Other: Breathing exercise · Other: Aerobic Exercise
The control group continued their routine lives, and at the end of three weeks
Volunteers participating in the study who were included in the experimental group performed breathing exercises every day for three weeks. They were taught to focus their attention on the hand on their abdominal area while breathing slowly through their nose and to increase abdominal movement while reducing chest movement. They were warned that during inspiration, as air filled their lungs, the hand on their abdomen should rise upward and the hand on their chest should not move excessively. Participants continued the training until they performed the exercise correctly. The diaphragmatic breathing exercise was performed for 10 minutes in the supine position during the first week, in the semi-sitting and/or sitting position during the second week, and in the standing position during the final week.
The ratios determined as reference values for walking training in healthy adults (reference value for women = (2.11\*height) - (2.29\*body weight) - (5.78\*age) + 667 meters - reference value for men = (7.57\*height) - (1.76\*body weight) - (5.0 2\*age) - 309 meters) was performed at 80% intensity for at least 30 minutes on at least 3 days a week for 3 weeks. Aerobic exercise was considered for 3 weeks to facilitate adaptation to exercise and sustainability.
Oxidative stress biomarkers
It has been reported that the interaction between oxidative stress and the immune system is important, and that activated immune inflammatory pathways can trigger oxidative stress. In our study, an ELISA test will be conducted to investigate how exercise affects the levels of oxidative stress (TAS, TOS, MDA, and F2-isoprostane) biomarkers, which play a role in the pathophysiology of depression.
Time frame: From enrollment to the end of treatment at 3 weeks
Proinflmatuar sytokines
It is believed that increased production of key proinflammatory cytokines such as interleukin tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and interleukin-1 (IL-1) and acute phase reactants plays an important role in the development of depression as a result of immune system involvement. In our study, an ELISA test will be conducted to investigate how exercise affects the levels of inflammation (TNF-α, IL-6, IL-1) which play a role in the pathophysiology of depression.
Time frame: From enrollment to the end of treatment at 3 weeks
