Effect of Aerobic Exercise on Biomarkers in Depression

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.
