Brief summary
The aim of this study is to examine the peripheral muscle oxygenation of patients with Chronic Obstructive Pulmonary Disease at rest, during submaximal exercise and recovery, and to examine the effects of disease severity and respiratory functions on peripheral muscle oxygenations. In this study, the effect of disease severity and respiratory problems on peripheral muscle metabolism of patients with COPD will be explained.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Muscle oxygenation | one day | The muscle oxygen monitor is a lightweight (42 g) and small (dimensions: 61 × 44 × 21 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| COPD Assessment Test (CAT) | one day | The COPD Assessment Test (CAT) is a new scoring system for COPD patients, which provides a simple method for assessing the impact of COPD on the patient's health. Range of CAT scores from 0-40. |
| Charlson Comorbidity Index | one day | The Charlson Comorbidity Index was first developed in 1987 by Mary Charlson and colleagues as a weighted index to predict risk of death within 1 year of hospitalization for patients with specific comorbid conditions. Nineteen conditions were included in the index. The total score in the CCI is derived by summing the assigned weights of all comorbid conditions presented by the client. Higher scores indicate a more severe condition and consequently, a worse prognosis. |
| Quadriceps muscle strength measurement | one day | Quadriceps muscle strength measurement of the patients will be evaluated with a manual muscle strength measuring device (Lafayette Instrument, USA) and recorded in kg/force. In muscle strength measurements, maximal voluntary isometric contraction (make test), which is reported to be more reliable in the literature and is frequently used, will be used. It will be repeated three times in both lower extremities with an interval of 30 seconds and the highest measurement will be recorded. For quadriceps muscle strength measurement, the patients will be seated on the treatment table with their legs hanging down and the thigh will be fixed by placing a rolled towel under the knee joint of the side to be evaluated. In this position, the patient will be asked to extend until the knee is locked, and the resistance will be given just above the ankle joint. |
| Modified Medical Research Council Dyspnea Scale | one day | Medical Research Council (MRC) Dyspnea Scale will be used to assess the severity of dyspnea. The severity of dyspnea during activities of daily living is graded from 0 to 4 on the Medical Research Council (MRC) Dyspnea Scale. |
| Pulmonary Function Test | one day | Pulmonary function will be evaluated with the spirometry. Dynamic lung volume measurements will be made according to American Thoracic Society and European Respiratory Society criteria. |
| Maximum Inspiratory Pressure / Maximum Expiratory Pressure Measurement | one day | Respiratory muscle strength of individuals will be measured using an electronic and portable oral pressure measurement device, according to ATS / ERS criteria, with COSMED brand Pony FX model portable spirometer (COSMED, Italy). It is one of the most commonly used and noninvasive methods for the evaluation of respiratory muscle strength. With this method, maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) are measured. MIP and MEP are intraoral pressures measured during maximal breathing against a valve that closes the airway during maximal inspiration and expiration. |
| Six-minute walking test | one day | It is a submaximal exercise capacity measurement test. The patient is asked to walk as briskly as possible on a flat surface of 30 meters for 6 minutes. In our study, the test will be carried out in a 30-meter corridor in accordance with the guidelines. |
