What researchers measure

Primary outcomes

  1. Six-minute walking test

    The 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

    Time frame: 1 day

  2. Maximal voluntary breath-hold time

    The 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.

    Time frame: 1 day

    Time frame: 1 day

  2. Fagerstrom Nicotine Addiction Test

    Dependence analysis will be performed on smokers according to the Fagerström nicotine addiction test and the scales for evaluating the psychological dependence of cigarettes. It is a six-question questionnaire created by revising the Fagerstrom tolerance questionnaire. In the scoring made according to the answers given to the questions, 0-2 points is called very mild addiction and 8-10 points is called very severe addiction

    Time frame: 1 day

  3. Evaluation scale of psychological dependence on cigarette
