Interventions

Participants were incorporated in an exercise program of moderate intensity (walking on the treadmill) 3 times weekly for 48 weeks

the first 12 weeks were supervised and the remaining 36 weeks of the program were unsupervised. The duration of complete training sessions was of 30 minutes the first three weeks, 40 minutes the next

Design outcomes

Primary

Measure	Time frame
1. Measurement of Oxygen saturation (SaO2). Pulse Oximeter CMS 50DL Finger Pulse Oximeter SaO2 was used to measure SaO2. It was measured one week prior training; pulse oximeter was utilized to measure SaO2 in the right index of each individual. Each individual had to rest for two minutes before the beginning of the measurement. After placing the sensor on the finger, we waited until a reading was displayed on the oximeter, then we waited for another 10-15 seconds to verify a steady signal, this is followed by recording SaO2 and pulse every 10 seconds. Six observations were recorded and their average was used as the individual’s SaO2 as in previous studies. These measurements were taken in a specific cardiopulmonary test, regardless of the training sessions. 2. Measurement of Maximum Oxygen consumption (VO2max). A Cardiopulmonary Exercise Test unit (CPET) Zan 800, a gas analyser of O2 and CO2 was used for the measurement of VO2max. Before conducting the test, the humidity collector was cleaned, the connected tube was checked, and the triple V- valve sensor disinfected and the gas analyser calibrated. The heart rate and blood pressure were recorded in the relaxed sitting position for each subject of the group. The mask was fixed with straps and then the triple tube V was connected to the mask. Initially, metabolic parameters such as oxygen consumption, carbon dioxide production and heart rate at rest were measured every three minutes. These measurements were taken in a specific cardiopulmonary test, regardless of the training sessions. 3. Maximal Walking Distance (MWD). This data was obtained from the treadmill DKN Run Tech 2.5. MWD is displayed on the screen. MWD data at baseline was recorded from an exercise test, the same test displayed in the first period of training sessions (warming up phase of 5 minutes on the treadmill, 20 minutes of active phase, and cooling down phase for a period of 5 minutes). At the 12th, 30th and 48th week, MWD was recorded from the tr	—
