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.

Zeitfenster |
|---|---|---|
|
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.

Baseline and after 8 weeks of intervention
|
|
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.

Serum Brain Natriuretic Peptide Level
Zeitfenster: Baseline and after 8 weeks of intervention
|
Serum brain natriuretic peptide levels will be assessed using blood samples collected from all participants before and after the 8-week intervention.
Biochemical analyses will be performed by the responsible physician.
Serum BNP level will be used as a biomarker related to cardiac load and ventricular dysfunction in patients with heart failure.
|
Baseline and after 8 weeks of intervention

|
Functional Capacity
Zeitfenster: Baseline and after 8 weeks of intervention
|
Functional capacity will be assessed using the 6-Minute Walk Test according to standardized procedures.
Participants will be instructed to walk as far as possible at their own pace in a 30-meter corridor for 6 minutes.
The total distance walked at the end of the test will be recorded in meters.
