Two recent studies show that of all things, nitrate-rich beetroot juice, increases stamina during exercise and also lowers blood pressure . The two groups of researchers are not sure of what the mechanism behind the benefit is but they think it has something to do with the nitrate from the juice turning into nitric oxide which in turn reduces the O2 cost in exercise.
