      Background Recent randomized controlled trials have suggested that dietary nitrate (NO3-), found in beetroot and other vegetables, and inorganic NO3− salts decrease metabolic rate under resting and exercise conditions. Objective Our aim was therefore to determine from a systematic review and meta-analysis whether dietary NO3− supplementation significantly reduces metabolic rate, expressed as ...
    • Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercisePeer reviewedClosed access

      Dietary nitrate (NO3−) supplementation has been shown to increase exercise tolerance and improve oxidative efficiency during aerobic exercise in healthy subjects. We tested the hypothesis that a 3-day supplementation in beetroot juice (BJ) rich in NO3− would improve the tolerance to supramaximal intensity intermittent exercise consisting of 15-s exercise periods at 170% of the maximal aerobic power ...
    • Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained menPeer reviewedClosed access

      Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis that could limit oxygen (O2) delivery in the working skeletal muscles by altering endothelium‐dependent vasodilatation. Exercise capacity is associated with plasma ADMA concentrations in patients with cardiovascular diseases, but this issue has still not been investigated in healthy subjects. We aimed to ...
