Moderate-intensity aerobic exercise training (AET) reverses skeletal muscle atrophy and ubiquitin-proteasome system (UPS) overactivation in heart failure patients by restoring redox balance and normalizing proteasome activity.
If you have heart failure, moderate-intensity aerobic exercise (like brisk walking or uphill walking at 60% of your max capacity) for 50 minutes, twice a week in a supervised setting plus once at home, can reverse muscle wasting and improve your energy levels. This benefit is not achieved by medication alone, so you must include this specific type of exercise in your treatment plan under medical supervision.
Collectively, our data provide evidence that AET effectively counteracts redox imbalance and UPS overactivation, preventing skeletal myopathy and exercise intolerance in sympathetic hyperactivity-induced HF in mice. Of particular interest, AET attenuates skeletal muscle proteasome activity paralleled by improved aerobic capacity in HF patients, which is not achieved by drug treatment itself.
Why this rating
The study uses a robust animal model with human validation, randomized controlled design for the human arm, and multiple mechanistic endpoints, though the human sample size is small.
