DAILY FITNESS TIP: Drinking beat juice for days on end may make you run/swim/pedal a little bit better! You're welcome!
Some of our endurance-nerd friends here in Bend have been slamming beet juice all summer in the hopes that it will improve blood and oxygen flow to muscles, as is the claim. It MUST be semi-legit because the New York Times just ran this story. The article is based, in part, on this study from PubMed which found the following:
Dietary nitrate supplementation has been shown to reduce the O2 cost of submaximal exercise and to improve high-intensity exercise tolerance. However, it is presently unknown whether it may enhance performance during simulated competition. The present study investigated the effects of acute dietary nitrate supplementation on power output (PO), VO2, and performance during 4- and 16.1-km cycling time trials (TT).
Whoa. Lots of science gobbledygook. We can tell you this: It's tasty but kind of expensive. Mother's is your best bet for getting it locally unless you have your own juicer. Let us know if it helps. It's got to be better for you than this can of Olympia .... though less economical.
I wonder if Ashton Eaton is a beet juice drinker?
