(OrganicJar) Drinking beetroot juice boosts stamina and could help people exercise for up to 16% longer, a UK study suggests.
A University of Exeter team found that the nitrate contained in the vegetable leads to a reduction in oxygen uptake, making exercise less tiring. The study suggests the effect is greater than that which can be achieved by regular training.
Beetroot juice has previously been shown to reduce blood pressure.
The researchers believe their findings could help people with cardiovascular, respiratory or metabolic diseases and endurance athletes.
They focused on eight men aged 19-38, who were given 500ml per day of organic beetroot juice for six consecutive days before completing a series of tests, involving cycling on an exercise bike.
On another occasion, they were given a placebo of blackcurrant cordial for six consecutive days before completing the same cycling tests.
After drinking beetroot juice the group was able to cycle for an average of 11.25 minutes – 92 seconds longer than when they were given the placebo.
This would translate into an approximate 2% reduction in the time taken to cover a set distance.
The group that had consumed the beetroot juice also had lower resting blood pressure.
Why Does This Happen
The researchers are not yet sure of the exact mechanism that causes the nitrate in the beetroot juice to boost stamina. However, they suspect it could be a result of the nitrate turning into nitric oxide in the body, reducing how much oxygen is burned up by exercise.
Study researcher Professor Andy Jones – an adviser to top UK athlete Paula Radcliffe – said: “We were amazed by the effects of beetroot juice on oxygen uptake because these effects cannot be achieved by any other known means, including training.
“Certainly, a diet high in nitrate-rich fruits and vegetables is good for your heart health and this study provides further evidence of this.”
I love beet juice!! If you follow me on twitter (@OrganicJar) you know I am always juicing beets. My favorite recipe: beets, carrots, cucumbers with a splash of coconut water!
Also, don’t forget to juice the ‘stem and leaves’ of the beets as they are full of nutrition, some studies I’ve read say they are more nutrient dense than the beets themselves.
