Combined strength and aerobic training vs. aerobic training alone in patients with heart failure: A systematic review and meta-analysis

In predominantly male patients with HFrEF, combined training yielded greater improvements in CRF, 6MWT distance, and upper body strength than AT alone. Replacing part of aerobic training with muscle strength training may be an effective strategy to further enhance CRF in HFrEF. Also, HIIT may be combined with muscle strength training to induced further increases in CRF. Further evidence is needed to clarify the effects of combined training in HFpEF.
