The triad of physical activity: An optimal combination for cardiovascular health.

The combination of moderate to vigorous physical activity with muscle-strengthening physical activity is increasingly recognized for its significant impact on cardiovascular health. This narrative review synthesizes current evidence to compare the cardiovascular benefits of combined physical activity versus singular forms, especially in primary prevention. The main focus is on hormonal, nervous, genetic, and molecular adaptations, critical mechanisms underlying the body's response to physical activity. Our findings endorse superior benefits for combined moderate to vigorous and muscle-strengthening physical activity for preventing cardiovascular disease (CVD). This combined approach synergistically enhances cardiovascular function and more effectively reduces risk factors than either activity alone. While more research is needed to distinguish between moderate and vigorous activity levels in combination with muscle-strengthening physical activity, current evidence supports comprehensive physical activity guidelines that maximize cardiovascular health. These findings highlight the importance of integrated physical activity regimens in public health strategies and clinical practice to mitigate the global CVD burden.
