简要总结
This is a single-center randomized controlled trial evaluating the efficacy and safety of short (3 days) versus long (10 days) courses of intermittent hypoxic-hyperoxic training (IHHT) in patients with type 2 diabetes mellitus aged 50-74 years. Participants will be randomized into three groups: 3-day IHHT course (n≥100), 10-day IHHT course (n≥100), or control group receiving gas mixture with constant O2 21% for 10 days (n≥50). The primary outcomes are fasting glucose levels and HbA1c. Secondary outcomes include cardiovascular parameters, quality of life, cognitive function, and biological age.

盲法说明
Participants in Groups 2 (10-day IHHT) and 3 (control/sham) are blinded to their group assignment and do not know whether they are receiving active IHHT or breathing normoxic gas mixture (21% O2). Group 1 (3-day IHHT) participants are aware of their intervention due to the different duration. All interventions are conducted in separate rooms with identical equipment. Medical personnel conducting the interventions are not blinded.
