Blood Flow Restriction Combined With Aerobic or Resistance Exercise in Heart Failure
31. Mai 2026 aktualisiert von: FATMA DİLARA AKAR ÇAMYAR, Biruni University
Comparison of the Effects of Aerobic or Resistance Exercises Combined With Blood Flow Restriction on Muscle Oxygenation, Serum BNP Levels, Functional Capacity, and Quality of Life in Patients With Heart Failure
The aim of this study is to compare the clinical effects of aerobic and resistance exercise modalities combined with blood flow restriction in patients with stable heart failure, and to determine the most effective, feasible, and evidence-based rehabilitation approach.
In individuals with heart failure, limited exercise tolerance increases the importance of training strategies that can induce high physiological adaptations with low mechanical loads.
In this context, exercise interventions combined with blood flow restriction have attracted increasing attention due to their low-intensity nature and potential clinical benefits.
This study is designed as a prospective, parallel-group, randomized controlled clinical trial to be conducted in 40 patients diagnosed with stable heart failure.
Participants will be randomized into two groups: a blood flow restriction- combined aerobic exercise group and a blood flow restriction-combined resistance exercise group, both applied under supervision three times per week for eight weeks.
All participants will be assessed before and after the intervention in terms of muscle oxygenation, serum B-type natriuretic peptide (BNP) levels, functional capacity, and quality of life.
The expected outcome of this study is to obtain comparative data on the clinical effectiveness of blood flow restriction- combined exercise interventions in patients with stable heart failure and to identify which exercise modality provides superior clinical benefits.
The findings are anticipated to contribute to the development of short-term, low-cost rehabilitation protocols and to provide evidence-based guidance for clinical practice.

Intervention / Behandlung |
|---|---|
|
Experimental: Aerobic Exercise Plus Blood Flow Restriction Resistance Training
Participants in this group will receive an 8-week combined exercise program consisting of moderate-intensity aerobic exercise followed by blood flow restriction resistance training.
|
Participants will receive an 8-week supervised combined exercise program performed 3 days per week on non-consecutive days.
The intervention will include moderate-intensity aerobic exercise on a cycle ergometer at 40-70% of heart rate reserve, followed by lower extremity-focused blood flow restriction resistance training using low loads corresponding to 20-40% of one-repetition maximum and cuff pressure set at 50% of arterial occlusion pressure.
Each session will include a 5-10-minute warm-up and a 5-10-minute cool-down period.

Experimental: Resistance Training Plus Blood Flow Restriction Aerobic Exercise
Participants in this group will receive an 8-week combined exercise program consisting of conventional resistance training followed by blood flow restriction aerobic exercise.
|
Participants will receive an 8-week supervised combined exercise program performed 3 days per week on non-consecutive days.
The intervention will include conventional resistance training targeting major muscle groups at 40-60% of one-repetition maximum, followed by blood flow restriction aerobic exercise on a cycle ergometer at 40-70% of heart rate reserve.
Cuff pressure will be set at 50% of arterial occlusion pressure, and the cuffs will remain inflated only during the aerobic exercise period.
Each session will include a 5-10-minute warm-up and a 5-10-minute cool-down period.

Muscle Oxygen Saturation
Zeitfenster: Baseline and after 8 weeks of intervention
|
Muscle oxygen saturation will be assessed using near-infrared spectroscopy with the Moxy Monitor® device.
The device will be placed over the quadriceps muscle group, and muscle oxygen saturation values will be recorded.
SmO₂ reflects the balance between oxygen delivery and oxygen utilization in the working muscle.
Measurements will be obtained before and after the 8-week exercise intervention, and the mean SmO₂ value recorded during the measurement period will be used for analysis.

Total Hemoglobin
Zeitfenster: Baseline and after 8 weeks of intervention
|
Total hemoglobin will be assessed using near-infrared spectroscopy with the Moxy Monitor® device placed over the quadriceps muscle group.
Total hemoglobin reflects local blood volume and hemodynamic changes in the measured muscle region.
Measurements will be obtained before and after the 8-week exercise intervention, and the mean THb value recorded during the measurement period will be used for analysis.
