Does moderate-to-high intensity resistance training improve exercise capacity and quality of life in patients with chronic heart failure?
Current evidence is inadequate to recommend moderate-to-high intensity resistance training for patients with chronic heart failure due to inconclusive results and methodological limitations of existing trials.
CONTEXT: Resistance training may be beneficial for patients with chronic heart failure (CHF). OBJECTIVE: To systematically review the methodological quality of, and summarise the effects of, moderate-to-high intensity resistance training in CHF. DATA SOURCES: Medline/PubMed, Science Citation Index Expanded, SSCI and A&HCI. STUDY SELECTION: English language (non-)randomised controlled trials. DATA EXTRACTION: A predesigned data extraction form was used to obtain data on trial design and relevant results. Methodological quality of the identified trials were scored using the Delphi list. RESULTS: Most of the 10 trials identified had moderate-to-severe methodological limitations. Effects of resistance training (alone or in combination with endurance training) are inconclusive for outcomes like exercise capacity and disease-specific quality of life. CONCLUSIONS: Even though moderate-to-high intensity resistance training does not seem be harmful for patients with CHF, the current peer-reviewed evidence seems inadequate to generally recommend incorporation of resistance training into exercise-based rehabilitation programmes for patients with CHF.
