"Hypoxic vs. Aerobic Training in Chronic Kidney Disease

Sponsor: Pharos University in Alexandria

View on ClinicalTrials.gov

Summary

Chronic kidney disease (CKD) leads to poor exercise tolerance, vascular dysfunction, and reduced quality of life. This randomized controlled trial will compare intermittent hypoxic training (IHT) with traditional aerobic training in patients with CKD stages 3-4. A total of 60 participants aged 40-65 years will be recruited and randomized into three groups. Interventions will last 12 weeks, with three 30-minute supervised sessions per week. Outcome measures include exercise tolerance (6-Minute Walk Test), cardiovascular parameters (blood pressure, heart rate recovery), kidney function (serum creatinine, eGFR), fatigue (Fatigue Severity Scale), and quality of life (KDQOL-36)

BEHAVIORAL

hypoventilation group

Traditional Aerobic Training Participants will perform supervised aerobic exercise (e.g., cycling or treadmill walking) under controlled intermittent hypoxic conditions. Hypoxia protocol: alternating cycles of low-oxygen exposure (FiO₂ 12-16%) for 3-5 minutes followed by normoxic recovery for 2-3 minutes, repeated 6-8 times per session. Frequency: 3 sessions per week for 12 weeks. Exercise intensity: Moderate (50-70% of heart rate reserve), adjusted individually based on baseline exercise testing
