Purpose of review: The aim of this study was to determine the effects of aerobic exercise on peak oxygen uptake (peak VO<sub>2</sub> ), minute ventilation/carbon dioxide production (VE/VCO<sub>2</sub> slope), and health-related quality of life (HRQoL) among patients with heart failure (HF) and preserved ejection fraction (HFpEF). Recent findings: We conducted a Cochrane Library, MEDLINE/PubMed, Physiotherapy Evidence Database, and SciELO search (from 1985 to May 2019) for randomized controlled trials that evaluated the effects of aerobic exercise in HFpEF patients. We calculated the mean differences (MD) and 95% confidence interval (CI). Ten intervention studies were included providing a total of 399 patients. Compared with control, aerobic exercise resulted in improvement in peak VO2 MD 1.9 mL kg-1 min-1 (95% CI 1.3 to 2.5; N = 314) and HRQoL measured by Minnesota Living with Heart Failure MD 5.4 (95% CI - 10.5 to - 0.2; N = 256). No significant difference in VE/VCO<sub>2</sub> slope was found between participants in the aerobic exercise group and the control group. The quality of evidence for peak VO<sub>2</sub> and HRQoL was assessed as being moderate. Aerobic exercise moderately improves peak VO<sub>2</sub> and HRQoL and should be considered a strategy of rehabilitation of HFpEF individuals.
