Effects of Short and Long Courses of Intermittent Hypoxic-Hyperoxic Training in Patients With Type 2 Diabetes Including Elderly (EFIR)
A Single-Center Randomized Clinical Trial With Prospective Follow-up of the Efficacy and Safety of Short and Long Duration Intermittent Hypoxic-Hyperoxic Training in Patients With Type 2 Diabetes Mellitus Including Elderly Patients
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.
