      Beetroot juice (BR) has gained considerable research interest for its ergogenic effects in regards to improving exercise and sports performance. This increased interest is due to BR, which is rich in inorganic nitrate (N03 − ), providing an alternative pathway for increasing the pools of bioavailable nitric oxide (NO) in the body. The literature has investigated the effects of BR in a variety of exercise and sporting scenarios. Of such, the vast majority has focused on trained populations in aerobic scenarios with chronic and acute dose protocols, while other research has focused on recreationally active populations. The outcomes of the research have not always been consistent, with many studies demonstrating significant ergogenic benefits of BR and others unable to provide favourable outcomes. It is clear from the research reviewed that BR can be used as an ergogenic aid in recreationally active, trained and clinical subjects. Although not all studies agree, performance outcomes range from reduced time to completion (TTC) and oxygen uptake (V̇O2) and increased power output (PO) and exercise tolerance, all of which have been demonstrated in well controlled study designs. Research is vast, particularly in trained populations, with this leading to a need for further research in recreationally active populations. In addition, the overwhelming majority of these studies have been conducted on males, both recreationally and trained, which opens up a requirement for specific female focused studies within the literature.
