EXERCISE TRAINING PROGRAMS AND CARDIOVASCULAR DISEASES IN ADULTS: A NARRATIVE REVIEW 2020-2025
Introduction. Cardiovascular diseases (CVD) remain the leading cause of death worldwide. Physical inactivity represents a major modifiable risk factor. In this context, physical exercise has been consolidated as an essential therapeutic tool for the prevention and management of CVD, although questions persist regarding the optimal modalities, intensities, and conditions of prescription in adults.
Objective. To summarize the scientific evidence published between 2020 and 2025 on the effects of different physical training programs in adults with CVD or within prevention programs, considering their components, intensities, physiological mechanisms, safety criteria, and adherence factors.
Methodology. A narrative review with an interpretative and thematic approach was conducted. The databases Web of Science, Scopus, ScienceDirect, and SciELO were consulted, including experimental, quasi-experimental, and systematic review studies, as well as clinical guidelines on non-athlete adult populations published in Spanish and English.
The studies were grouped into the following themes: exercise prescription, intensity, strength training, exercise adherence, physiological mechanisms, and safety.
Results. A total of 24 studies were analyzed, highlighting programs that combine resistance and strength training, which generate significant improvements in cardiorespiratory capacity, vascular function, and quality of life. Exercise intensity and adherence emerged as key determinants of clinical impact. High-intensity interval training (HIIT) was identified as a safe and effective modality when applied in an individualized and supervised manner. Key physiological mechanisms included mitochondrial, anti-inflammatory, and endothelial adaptations.
Conclusions. Physical exercise prescribed in an individualized, progressive, and supervised manner constitutes an effective and safe strategy for the prevention and management of CVD in adult populations. Personalizing exercise intensity and strengthening adherence are essential to maximize clinical benefits.
