Does exercise affect genes

Exercise, a new study finds, changes the shape and functioning of our genes, an important stop on the way to improved health and fitness.The researchers believe it is these alleles that cause people's bodies to respond differently to the same exercises.The purpose of the study was to determine how our genes can affect three types of physical activity:It appears that exercising is particularly important for those who are genetically predisposed to being overweight.Skeletal muscle phenotypes there is compelling evidence to the effect that there is a significant genetic component to human variation in skeletal muscle strength and endurance [see.

In fact, research has shown that there are hundreds or even thousands of.The field of epigenetics looks at how exercise, diet, and other environmental factors can affect how those genes are expressed.Now add one more thing to the list:But it's clear that, as with cardiovascular risk, physical activity can reduce a person's overall risk.In total, the study identified 13 genes, and associated alleles, as being responsible for how well the body reacts to cardiovascular fitness, muscular strength, and anaerobic power exercises.

On average, exercise weakened the variant's effects by about 30 percent, the researchers reported in the april 27 issue of plos genetics.A significant genetic effect is also observed in hr, blood pressure, sv, and q changes during submaximal exercise intensities in response to exercise training.One of those genes is called ace, and certain versions are associated with aerobic fitness in endurance athletes.
