Beets, Activfuel+ and improved performance

Some new research to chew on before your next big race, courtesy the good folks at Canadian-based Genuine Health …

Did you know that eating beets before a race might make you run faster?

A new study shows that eating 200 grams of baked beets (approximately two small beets) 75 minutes before exercise improved the running performance of recreationally fit men and women. Murphy, M., Eliot, K., Heuertz, R., Weiss, E. Whole beetroot consumption acutely improves running performance. J Acad Nutr Diet. 2012 Apr;112(4):548-552.

The increase in performance was most likely due to the conversion of the dietary nitrate to nitrite to nitric oxide in the body. Nitric oxide reduces the oxygen cost of exercise by requiring your muscles to use less energy or ATP to produce the same amount of work.

The researchers found was that the average running velocity was slightly faster (3%) after eating the beetroot compared to the placebo 12.3+ 2.7 vs 11.9+ 2.6 km. Interestingly, the difference was greatest (5%) during the last mile.

While the difference may not look like much, a 3% faster running velocity translates to about a 41 second faster finishing time. In a short race like a 5-km run, 41 seconds is a lot! For example if your pace is 8 minutes per mile, you would finish a 5 km in 24:51 minutes. But if you ate 200 grams of beetroot before the run you could potentially shave 3% off of your time.
