Carlos Bernal-Mizrachi1 & Clay F Semenkovich1


'Survival of the fittest' is based in part on the notion that genetic selection allows individuals to escape predators in the wild. A recent study indicates that selection for increased aerobic capacity may afford protection from cardiovascular risk factors associated with the metabolic syndrome.


The metabolic syndrome—perhaps the most common disorder in industrialized countries—represents a cluster of risk factors imparting a substantial risk of cardiovascular disease. Cardiovascular disease is the most common cause of morbidity and mortality in the developed world, and the striking frequency of metabolic syndrome in children and adolescents portends a new epidemic of vascular disease.
