Maybe, with his love for beets, Dwight was on to something after all. While, I might not go out and start a beet farm, it turns out that beet juice can provide increased athletic endurance. Apparently it’s the juice’s nitrate content that’s responsible for the benefit. Although the exact mechanism isn’t known, it’s thought that the nitrates help improve energy efficiency in the muscles. Another benefit of beet juice is that it can help lower systolic blood pressure by relaxing the blood vessels.
The benefits of drinking beet juice are dose dependent, with the best results obtained by consuming 240 to 500 ml of beet root juice approximately 2 hours before exercising. One study found that consuming beet juice extended time to failure by 14%!
