Study says genes determine fitness outcomes

　　20% of people will inherit their parents’ “no healthy Gene". No matter how you exercise exercise , they will still be out of breath and weak in action.

Researchers believe that DNA affects the fat-burning effect of fitness exercises. In the future, people may be able to know the fitness method that suits them through a simple blood test.

14 fitness institutions around the world conducted tracking research by measuring the oxygen uptake of more than 600 fitness volunteers. Oxygen uptake is one of the indicators of the heart's blood transfusion capacity and is also a key factor in health and longevity. Aerobic activities such as running and brisk walking will increase the body's ability to absorb and consume oxygen, and improve the body's immune level.

Researchers tested the DNA of volunteers and found that a total of 30 genes affect the body's ability to absorb oxygen, 11 of which are closely related to physical fitness.

Genetic research results show that about 20% of volunteers still have difficulty improving their oxygen absorption capacity even if they exercise more.

“"There was almost no change in their physical fitness," said researcher James Timmons. "People would say we're only looking at one fitness metric, and the benefits of aerobic exercise are many." This is certainly true. However, oxygen uptake is the most authoritative and quickest indicator for predicting longevity. ”

The report published in the Journal of Applied Physiology also pointed out that another 10% of the volunteers significantly improved their physical fitness through aerobic exercise.

Researchers have patented a blood test that can identify "unhealthy genes" and believe it could be on the market within a year.
