Thought I'd start a new thread here away from the Recession thread...
Anyway, I know certain forumites have their doubts about this but, having looked at a lot of the research, spoken to various elite athletes and tried it myself, there does seem to be something to this. Studies on nitrate supplementation and exercise go back to 2007. Yes the link to this study is via a company with a vested interest but the study was conducted before the company existed.
As an study, the methodology seems sound and ongoing work, especially at the University of Exeter, seems to be backing it up.
I first heard about it in a pub after one of the Human Race Off-Road Duathlons. I was with Richard Stannard (top GB triathlete) who'd just come second (I'd managed a reasonable 8th) and he was raving about beetroot juice and how all the pros were using it. I looked into it and gave it a go. Once I'd got over the rank taste (I hate beetroot) and pink pee and poo, I certainly felt stronger and, on the bike especially, was posting faster splits late on in training rides. This was on 500 ml per day.
I'm now trying the Beet-It concentrated shots that give you the same amount of nitrates but in a 70ml dose. I'm taking them in the week leading up to the HellRider (8 hour trail run/mountain bike enduro) next weekend and will let you know how it goes.
Anyone else given it a go?
