To investigate whether chronic supplementation with a low or moderate dose of dietary nitrate (NO3−) reduces submaximal exercise oxygen uptake (V˙O2) and to assess whether or not this is dependent on acute NO3− administration prior to exercise. Following baseline tests, 34 healthy subjects were allo...
