Introduction: heart failure (HF) is a serious disease that compromises the heart's ability to pump blood, generating significant morbidity and mortality. A critical component in the progression of HF is left ventricular (LV) remodeling, which further deteriorates cardiac function. Objectives: To evaluate the impact of resistance physical training on LV remodeling in patients with HF. Methodology: an exhaustive search of studies was carried out in databases such as PubMed, Scopus, Cochrane and Web of Science, covering the period between 2010 and 2024. 20 studies focused on strength and resistance training programs were selected, whose objective was to analyze the effect on ejection fraction (EF) and maximum oxygen consumption (Vo2max). The total sample included 450 patients diagnosed with HF, average age of 60 years (range: 45-75 years). Results: findings describe high-intensity interval training (HIIT) significantly improved cardiorespiratory fitness, outperforming moderate continuous training (MCT) in terms of Vo2max (Cohen's d = 0.27, p = 0.02). Regarding LVEF, both HIIT (d = -5.64, p < 0.001) and MCT (d = - 6.49) produce significant improvements, although high heterogeneity is observed in the results (I2 > 98%). Conclusions: both HIIT and MCT are effective interventions to improve cardiac function in patients with HF, with HIIT standing out in optimizing cardiorespiratory capacity and MCT for its accessibility in less trained populations.
