It’s all in the DNA: a study in the Journal-of Applied Physiology seems to suggest that one in five persons will stay fat no matter how much they work out. In other words, if you’re having trouble getting into your jeans, it’s not your fault, it’s your parents.
Researchers from 14 institutions around the world asked more than 600 people to take up cycling and tracked subsequent improvements in their aerobic fitness…
Around one in five of those tested had a combination of genes that meant their oxygen uptake hardly changed, despite weeks of fast pedalling.
The researchers aim to patent a blood test that would reveal the so-called unfitness genes. The test could be on the market by 2011. Test results theoretically could allow for a customized nutrition program instead of a fitness regimen or perhaps other kinds of exercise such as weight training rather than aerobics for those who inherited this genetic make-up.
