The ergogenic effects of dietary nitrate

In 2009, we published the first research study to demonstrate that supplementing the diet with nitrate-rich beetroot juice, which increases the availability of an important signalling molecule called nitric oxide, improves exercise economy and exercise tolerance.

We have subsequently published over 30 novel experimental studies that have explored:

  • The ergogenic effects of dietary nitrate supplementation in endurance and intermittent exercise
  • The mechanisms by which improvements in exercise economy and performance are manifest
  • The effect of dietary nitrate supplementation on training adaptations
  • The optimal dietary nitrate supplementation strategy.

We have also investigated the efficacy of other putative nitric oxide donors such as L-arginine, L-Citrulline and epicatechin. Moreover, we have published studies on other nutritional ergogenic aids such as creatine, sodium bicarbonate and caffeine.


Financial support for this line of research has been provided by industry partners including the Gatorade Sport Science Institute (GSSI, PepsiCo Inc), Beet It and GlaxoSmithKline (GSK).
