Work out for longer

Beetroot

Beetroot juice definitely increases your endurance during exercise and can help you train for longer.

A clinical study recently published in the American Journal of Physiology found that subjects who drank just 70ml of beetroot juice for 15 days had lower blood pressure and more dilated blood vessels at rest and during exercise. Blood vessels also dilated more easily and the heart consumed less oxygen when exercising.

The researchers said the findings suggest that beetroot juice can act as a dietary nutraceutical (a cross between a nutritional supplement and a pharmaceutical), capable of “enhancing oxygen delivery and reducing work of the heart such that exercise can be performed at a given workload for a longer period of time before the onset of fatigue”.
