Study Arms:
- Acute Intermittent Hypoxia Arm (Type: EXPERIMENTAL): AIH protocol: it consists of 15, 90-second hypoxic episodes (FiO2=0.09) interspersed with 15, 90-second normoxic intervals (FiO2=0.21) for a total time of 45 minutes. This protocol will be repeated every day for 5 consecutive days and then 3 times per week for 3 weeks. Total time: 4 weeks. After this AIH protocol, patients will received body weight-assisted treadmill training (BWSTT) for 45 minutes.
- Normoxia Arm (Type: PLACEBO_COMPARATOR): Sham protocol: it consists of continuous normoxia (FiO2=0.21) for 45 minutes for 5 consecutive days and then 3 times per week for 3 weeks. Total time: 4 weeks.After this AIH protocol, patients will received body weight-assisted treadmill training (BWSTT) for 45 minutes.

Based on this trial design, predict the completion outcome and termination type (if applicable).
