A GLASS of beetroot juice boosts endurance by reducing the amount of oxygen needed during physical exercise, a study says.
Subjects who drank the juice easily outperformed a control group in tests and were able to exercise at the same intensity for up to 16 per cent longer.
The findings, published in the US-based Journal of Applied Physiology, will be of keen interest to endurance athletes but may also prove helpful to people with cardiovascular, respiratory or metabolic diseases as well as the elderly, the researchers said.
