Beet juice contains high levels of nitrate. Recent research has proven that this is the key ingredient that led to improved performance, more than any other component of beet juice.
Recent research on the health benefits of beetroot juice to show not only athletes who can benefit increase in performance - physiological effects can help the elderly or people with heart problems or lung disease, enjoy life more active.
Beet juice has become one of the biggest stories in sports science over the past year after researchers at the University of Exeter found that the juice is allowing people to practice up to 16% longer. This surprising result has led to a number of athletes - from amateurs to professional players - are keen to use its potential.
New research from the university along with the Peninsula College of Medicine and Dentistry has revealed the physiological effects that drinking beetroot juice can help people more broadly.
In a recent study published in the Journal of Applied Physiology, the researchers observed a low-intensity exercise and found that test subjects used less oxygen while walking - effectively reducing the effort required to walk by 12%.
Katie Lansley, a PhD student from the Faculty of Sport and Health Sciences University and lead author of the study, said, "When you grow older, or if you have a condition that affects the cardiovascular system, then the amount of oxygen you can take to use during exercise, decreased sharply. That is, for some people, even simple tasks like walking also can not be managed.
"What we see in this study is that beetroot juice can actually reduce the amount of oxygen that you need to do even a low-intensity exercise. In principle, this effect could help people do things that would not otherwise be able to do. "
When consumed, beetroot juice has two physiological effects. First, it widens the blood vessels, lowers blood pressure and lets more blood flow. Second, it affects muscle tissue, reducing the amount of oxygen needed by the muscles during activity. The combination of these effects have a significant impact on the execution of physical tasks, whether it involves business, low-intensity or high intensity.
So far research on the effects of beetroot juice is only done to the young people who are in good health, but researchers believe that there is no reason why the effects of beetroot juice is not going to help others as well.
"Although we have not measured the impact on the elderly or those with heart problems or lung problems,
there is potential for positive impact in this population, where we intend to investigate further," added Katie Lansley.
Beet juice contains high levels of nitrate. Recent research has proven that this is the key ingredient that led to improved performance, more than any other component of beet juice.
Professor Andy Jones, senior scientist and pioneer of research studies beet juice, said, "In this study, we used - for the first time - a normal beet juice and beet juice that nitrate was filtered. The subjects who were tested did not know where they get. Both drinks looks and feels exactly the same. Each time the normal juice rich in nitrate is used, we saw a noticeable increase in performance that does not exist in the juices that have been filtered - so we know, nitratlah active ingredient. "
