Summary
High-intensity interval exercise safely improves walking ability in peripheral arterial disease patients. More exercise sessions correlate with greater rehabilitation score improvements, demonstrating program effectiveness.
Area of Science:
- Cardiology
- Exercise Physiology
- Vascular Medicine
Background:
- Peripheral arterial disease (PAD) significantly impairs walking ability and quality of life.
- Exercise therapy is a cornerstone of PAD management, but optimal intensity remains debated.
- High-intensity interval exercise (HIIE) offers potential benefits but requires safety evaluation in PAD patients.
Purpose of the Study:
- To investigate the safety and effectiveness of a structured high-intensity interval exercise program for patients with peripheral arterial disease.
- To assess the impact of exercise session frequency on functional improvement.
Main Methods:
- Observational study involving 47 patients with peripheral arterial disease.
- Patients performed treadmill walking to maximal claudication pain with intermittent rests.
- Rehabilitation score, calculated as the product of speed and grade, measured walking ability.
Main Results:
- Overall improvement in the rehabilitation score was observed with program participation.
- A positive correlation was found between the number of exercise sessions and the degree of improvement.
- No adverse events were reported, indicating good patient tolerance.
Conclusions:
- High-intensity interval exercise is a safe and effective intervention for improving walking ability in peripheral arterial disease patients.
- Increased participation in exercise sessions leads to enhanced functional outcomes.
- HIIE can be considered a viable therapeutic option for PAD management.
