An article in the Herald Sun August 8th states that the key to boosting stamina could be a glass of beetroot juice.

A daily dose is said to help us excercise longer and half a litre lowers blood pressure.

UK Researcher Andy Jones is said to be amazed by the effects of beetroot juice on oxygen uptake because these effects cannot be achieved by any other means , including training.

Obviously you get fitter with training but your oxygen uptake stays fixed.

The benefits are likely to be due to the high nitrate levels in beetroot juice.

The chemical is found in leafy vegetables such as lettuce and spinach but especially concentrated in juices.

It is thought that it undergoes a series of changes in the body that widen the blood vessels , widening and improving oxygen supply to the muscles.

Drinking the juice is likely to have another consequence - purple urine , or "beeturia".
