Recently more studies on the positive effects of beet root juice on exercise performance where published. Some scientists speculated that its positive effect on exercise performance is due to the high amount of dietary nitrate. A recent study by Lee, et.al. (Lee. 2010) found another plausible explanation for the performance boosting effects of beet root. Beet root is very high in betaine of which the researchers were able to show that following supplementation with 1.2g betaine twice a day test subjects improved bench press force, throwing force, and vertical jump power.
These results confirm those of a number of previous studies (Hoffmann. 2009; Armstrong, 2008), which found similar improvements in exercise performance.
