They will be included in exercise training as a group (three or four participants) with telerehabilitation (via Zoom application) for eight weeks. Exercise program includes: (F) 3 times a week, (I) at 60-70% of the maximum heart rate, (T): breathing, stretching, aerobic, plyometric, balance exercises, (T) 30 minutes each session, a total of 8 week. During the exercise sessions, the heart rate will be monitored via a Polar Unite Fitness Watch, and the oxygen saturations will be monitored with a pulse oximeter.

They will be individually included in exercise training with (via Zoom application) for eight weeks. Exercise program includes: (F) 3 times a week, (I) at 60-70% of the maximum heart rate, (T): breathing, stretching, aerobic, plyometric, balance exercises, (T) 30 minutes each session, a total of 8 week. During the exercise sessions, the heart rate will be monitored via a Polar Unite Fitness Watch, and the oxygen saturations will be monitored with a pulse oximeter.

They will continue their routine treatment (medical treatment, airway cleaning techniques, physical activity counseling).

Six-minute walking test: Before the test, oxygen saturation, heart rate, blood pressure, dyspnea and fatigue measurements are recorded. The patient walks for six minutes as fast as they can walk on the ground for at least 30 meters. The walking distance is recorded in meters. If the patient stops during the test, the total time he stopped, the number of times he stopped is recorded. After the test, the evaluations made before the test are repeated.

Modified shuttle walking test: It is a maximal test performed by adjusting walking speed with pre-recorded signals. Before the test, oxygen saturation, heart rate and blood pressure, dyspnea and fatigue will be recorded. The patient walks between two 10-meter points. Walking speed is increased every minute. The test is terminated when the required speed cannot be maintained or the speed cannot be followed. At the end of the test, the measurements are repeated.

For the peripheral muscle strength, the strength and grip strength of the knee extensor, hip flexor and abductor muscles in the lower extremity, and the elbow flexor, shoulder flexor and abductor muscles in the upper extremity will be examined. Measurement of muscle strength will be made with a Lafayette manual muscle tester, measurement of grip strength will be made with a Jamar hydraulic hand dynamometer. Evaluations will be made with the patient in a sitting position with back support. Evaluation of muscle strength will be done by evaluating the right and left extremities, and the grip strength will be repeated three times separately for the dominant hand and the non-dominant hand.
