Exercising makes you stronger and healthier, but new research says it can also change your DNA. Here's KOIN.
"Researchers found that exercise helps turn on genes in the muscle cells and reprogram them to make them stronger."
According to PressTV, the study, conducted in Stockholm...
"...[involved] 14 men and women who didn't usually exercise, [and] researchers examined the genes of participants' muscles before and after they spent 20 minutes on an exercise machine."
The result was less methylation in muscle cells. That's is a molecular process that involves chemicals called methyl groups settling on the DNA. As Time reports, this process...
"...[limits] the cell's ability to access, or switch on, certain genes..."
The underlying genetic code of the human muscle, the part inherited from your parents, doesn't change. But as Dr. Frank Lipman tells The Huffington Post...
"It is through the epigenome that environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that pass from one generation to the next... While each of us inherits our own unique, hardwired, unchangeable version of the genetic code, epigenetic factors such as lifestyle and diet can radically change what our genes do."
So how far do you have to push yourself in order to alter your DNA? According to Daily Mail,
"The person needs to be out of breath and while able to speak, have difficulty carrying out a conversation."
According to researchers, changes in methylation after exercise could lead to further investigation about exercise-induced diabetes prevention.
