Myth: Exercise cannot influence our epigenetics.
Truth: This is false.
Epigenetics is a chemical modification of our DNA that is dependent on our genetics and our environment, diet, and social activities. Epigenetics plays a central role in regulating mechanisms linked to cancer, metabolic disease, neurodegenerative disease, and other diseases. A study published in BMC Genomics examined how physical activity plays a role in influencing a person’s epigenetics.
Physical activity has been shown to improve gene regulation and metabolic processes. Specifically, the type of physical activity that one engages in also plays a role in how DNA can be modified. For example, high-intensity interval training has the potential to produce a cardiovascular adaptation to contribute to the maintenance of a stronger cardiovascular system.
