Primary

MeasureTime frameDescription
Six-minute walking test1 dayThe subject will be asked to walk for 6 minutes on a flat surface of 30 meters and the distance covered will be recorded. The test will be performed in accordance with the American Thoracic Society guidelines
Maximal voluntary breath-hold time1 dayThe maximum voluntary breath-hold test is a quick and simple test that consists of measuring the apnea time after a deep inspiration. The clinical utility of this test has been proven in certain respiratory pathologies. In the test, the subject will be seated in a chair with back support, a deep inspiration will be asked, and the breath-holding time will be recorded in seconds. The test will be repeated three times with sufficient rest periods in between, and the longest time will be analyzed.

Secondary

MeasureTime frameDescription
Thirty Seconds Sit and Stand test1 dayDuring the test, the individual performs the sit-stand-sit maneuver from a standard height chair within 30 seconds without using his arms as much as possible. The number of sitting and standing up during this period is recorded.
