Cardio exercise can outsmart "bad" genetics, new study says
Programs for you
Good news for those people with heightened genetic susceptibility to cardiovascular problems.
High levels of cardio fitness can reduce a person's risk of coronary heart disease. Erik Ingelsson, lead study author and professor of medicine at Stanford University, believes this is the largest-ever genetics study of its kind.
The study published in Circulation, the journal of the American Heart Association (AHA), proved that whether someone is already at low, intermediate or high risk, you still have a chance to trump up your genetics.
"Associations of Fitness, Physical Activity, Strength, and Genetic Risk With Cardiovascular Disease," published on April 9, surveyed nearly 500,000 adults living in the United Kingdom between the ages of 40 and 69.
The researchers tracked those who didn't show signs of heart disease for a decade, examining grip strength measurements and various exercise habits through questionnaires.
“Genes don’t have to determine destiny,” Ingelsson said of the study's findings. “You can impact your risk by being more fit. ... It was a very consistent pattern for all of these different measures. All were associated with lower risk of disease in the future.”
The specific examination was done concerning the genetic profiles of adults at the highest risk for atrial fibrillation, a heart rhythm disorder, with stationary bicycle tests.
As the Club Industry reports, overall, they found that those with the highest levels of cardio fitness reduced their risk of developing atrial fibrillation by 60 percent.
At the same time the similar assessment showed those on high levels of cardio fitness reduced coronary heart disease risk by 49 percent.
“[The researchers] demonstrated that physical activity and fitness were associated with a reduced risk of cardiovascular disease outcomes across a continuum of persons,” Russell Pate, a professor in the University of South Carolina’s Department of Exercise Science in the Arnold School of Public Health, told AHA.
“For the public, that’s an important message. You can’t eliminate genetic risk, but you can absolutely attenuate the effects.”
Have to admit that this research can become really fundamental in the future. For today heart disease is the leading cause of death in the world. So with further studies soon we would be able to minimize the effects of the disease and once to forget about them.
