As the saying goes, "Everything old is new again," but does that really apply to athletes from the Middle Ages?

As science continues to help athletes hold off the effects of Father Time, some are turning to medicine last used regularly in Roman times.

Science Daily reports riders at the Tour de France are drinking beetroot juice to help gain a competitive advantage.

Research by the University of Exeter, published in the journal Medicine and Science in Sports and Exercise, has shown drinking the juice helps competitive-level cyclists cut down the time it takes to ride a given distance. This is the first study which has shown that beetroot juice can be effective in a simulated competition environment.

While it's a stretch to say this product will have the same positive impact on athletes in other sports, it's a safe bet some savvy business person will try to capitalize on this research.

The smart money says you'll soon see sports nutrition companies mass marketing beetjuice to weekend warriors in the good old USA.

Maybe LeBron James will finally win a title after he starts kicking back some beetjuice.
