Muscle strength training improves cardiovascular health

A paper published recently in the scientific journal Nature Reviews Cardiology shows that regular physical exercise and, specifically, that which is undertaken to increase muscle strength, improves cardiovascular health through non-traditional mechanisms such as the skeletal muscle release of myokines or improvement in intestinal microbiota.

So understanding the pathways through which physical activity influences the various systems and organs of the could lead to new therapeutic strategies to attack the mechanisms of cardiovascular diseases. Mikel Izquierdo-Redín, professor in the Department of Health Sciences of the Public University of Navarre (NUP/UPNA) and researcher at Navarrabiomed has participated in this work.

"The loss of and mass is one of the 'forgotten' risk factors in ," said Mikel Izquierdo, head of the Physical Exercise, Life Cycle, Active Ageing and Health research group (E-FIT) and member of the Institute of Health Research of Navarre (IdiSNA). "Yet it can be corrected with a strength training programme, even in elderly individuals."

The authors of the paper stress that it is high time that physical exercise be regarded as "a medicine for treating cardiovascular diseases." They also stress that "unlike most drugs, exercise is largely free of adverse effects, and its benefits are to a certain extent dose-dependent." In other words, the doses of can be increased as the body adapts.

The little-known potential of physical activity

Yet the researchers lament the fact that "the huge potential of resistance and strength training to reverse both the disease and the effects of aging on muscle mass and thus improve gets scant recognition in the majority of clinical treatments."

Thus, they are putting forward "a comprehensive view of cardiovascular diseases in the context of the human body as a whole." They insist that the cardiovascular system (heart, blood vessels and blood) "should not be separated from the other organs, such as the above-mentioned skeletal muscles or intestinal microbiota, when addressing cardiovascular diseases." This comprehensive view includes not only the cardiovascular system, but also "the interaction between the heart and blood vessels with other tissue, including skeletal muscle, adipose tissue and even the intestine, by also using a range of approaches of an epidemiological, physiological and molecular type." In their view, this comprehensive perspective "could be of great help for health professionals who prescribe no for their patients."
