Do our genes influence our desire to exercise? The New York Times Share     Is the urge to exercise bred in our bones? That's the intriguing question that European researchers recently set out to examine by looking at the activity habits of 37,051 sets of twins. Twins are popular with geneticists, because they provide a neat statistical model for determining whether a behavior is influenced by genetics or exclusively by environment.

The study focused on men aged 19 to 38 cycling on exercise bikes. Drinking half a liter of beetroot juice a day for a week enabled them to cycle 16 percent longer before getting tired out. Now the scientists believe they understand how the beetroot boost works. More
