The Impact of Endurance and Strength Training on Quality of Life in Patients with Heart Failure: A Scoping Review

Background: Heart failure (HF) is a progressive condition associated with impaired functional capacity and reduced quality of life (QoL). In addition to pharmacological therapy, exercise-based interventions, including endurance and strength training, have been proposed as effective non-pharmacological strategies to improve outcomes. Objectives: This scoping review aimed to map the existing evidence on the impact of endurance and strength training on QoL in patients with HF, identify intervention characteristics, and highlight gaps for future research. Methods: A systematic search was conducted in PubMed, Scopus, Web of Science, Cochrane, and supplementary sources for studies published between January 2015 and September 2025. Eligible studies included randomized controlled trials, secondary analyses, and intervention reviews reporting QoL outcomes. Screening followed PRISMA-ScR guidelines, and data were extracted on study design, sample size, intervention type, and QoL measures. Results: Out of 1,060 identified records, six studies met inclusion criteria. Interventions included aerobic, resistance, and functional training programs. Most studies reported improvements in QoL, although results varied by exercise modality, patient characteristics, and measurement tools. Conclusions: Endurance and strength training appear to be safe and beneficial strategies to enhance QoL in HF patients. Standardization of protocols and long-term studies are needed to optimize clinical application.
