Exercise is not something that is capable of changing the genetic code of a human being, but it has been shown that DNA molecules do structurally and chemically change when people exercise. These changes are a sort of DNA modification that provides genetic reprogramming to increase muscle strength and help the body reap the benefits of exercise.
The type of modification that occurs to DNA is known as epigenetic modification and involves the change of chemical markers to the DNA which are beyond the normal DNA sequencing which involves a A, G, T and C.
A recent study has shown that when people exercise changes take place in the DNA and they are essentially responsible for turning on genes that adapt our body to be more suited to exercise. When people exercise it was shown that fewer chemical marks could be found on the DNA and this was confirmed with lab tests of muscle.
The turning off, or turning on, of these different genes is a very simple process for the body and it goes to show how flexible we can be towards exercise. The researchers on the study commented that by exercising we encourage our genome to make our health better.
