Your result, the one DNA position behind it, and what the research says.
4/10 confidence.
VEGF is the signal the body uses to grow new blood vessels, including the capillary networks that feed working muscle. That makes the gene an obvious place to look for differences in how people respond to training. One small cross-over study put thirty untrained young men through four weeks of resistance training and four weeks of endurance training, and found that men with two copies of the G version gained more strength from the lifting block than aerobic capacity from the cycling block. Thirty people is a very small study, and this card is offered as a curiosity, not as training advice.
Good to know: This rests on a single study of thirty men over four weeks, which is very small. VEGF drives the growth of the capillary networks that supply working muscle. Nothing here is a reason to choose one kind of training over another.
Fun fact: The study asked each man to do both kinds of training with a washout in between, so every participant acted as his own comparison.
Discovery: This variant was linked to differing training adaptations in 2023.
