Debate Over Significance of Cardio Fitness versus Muscular Strength for Long Life Expectancy?
A groundbreaking study published in The British Journal of Sports Medicine has revealed that a combination of moderate to vigorous physical activity, including both cardio and strength training, significantly reduces the mortality risk in American adults. The research, which involved a massive cohort of 416,240 individuals, suggests that this synergy can lead to a reduction in all-cause mortality by as much as 40%.
The findings are supported by a 2022 meta-analysis of over 370,000 adults. This study showed that resistance training alone reduced all-cause mortality by 15% and cardiovascular mortality by 19%. However, when resistance training was combined with aerobic exercise, the reduction in all-cause mortality increased dramatically to 40%.
Moderate amounts of strength training, around 60 minutes per week, yield near-maximal mortality benefits, with diminishing returns beyond that dose. Beyond extending lifespan, high levels of aerobic exercise have been linked to a reduction in biological aging, measured by longer telomeres—protective DNA caps tied to cellular aging. This is achieved by reducing oxidative stress, inflammation, and boosting cellular repair mechanisms such as telomerase activity.
The benefits of combining aerobic and resistance workouts extend beyond simply mortality. They improve overall health-related quality of life and may reduce stress in sedentary adults, highlighting broader health benefits.
In summary, the evidence strongly supports that combining cardio and strength training optimizes longevity benefits more than either modality alone. The synergy likely derives from cardio’s effects on cardiovascular health and cellular aging, plus strength training's impact on muscle mass, metabolism, and disease risk reduction.
