I'm sure we've all heard about beet juice as a performance enhancing supplement. Well, we may now have a more tasty (in my opinion) alternative.
Watermelon juice appears to have similar benefits:
The increase in time-to-exhaustion in a test that lasted about 10 minutes was 12 percent, which might correspond to a time-trial improvement of a bit less than 1 percent. There are many, many unanswered questions, such as whether trained athletes would get similar benefits.
I'm left wondering a few things that I suspect future studies will answer:
1) Is this real? Will future studies corroborate this result?
2) How does the benefit compare to beet juice?
3) Will taking both increase the benefit of taking either separately?
Obviously, more research is needed in this area and I'm sure it will be coming. The initial results, though, seem very interesting.
