BEETROOT JUICE EXERCISE LONGER
October 3, 2010 by USA Post
Determined to do better in this year’s race, Carver added something more to his training regimen: beat juice. For a week before the race, he drank the dark purple juice every day. Last month, Carver won by running 148 miles (238 kilometers).
“The only thing I did differently this year was the beet juice,” said Carver, 46, a professional rider based near Leeds in northern England.
He said the exercise would have improved his endurance, but to get the same result he attributed to the juice – eight extra miles – it would likely have taken a whole year.
Some experts say that adding beet juice to your diet – like other foods like cherry juice or milk – could provide a performance benefit, even beyond the blood, sweat and tears more training.
In two studies at the University of Exeter on 15 men, Stephen Bailey and his colleagues discovered the cyclists who drank half a liter (about half a pint) hours of beet juice before leaving several have been able to run up to 20 percent longer than those who drank a placebo juice blackcurrant.
In reviewing the cyclists under a scanner thatanlyzes the amount of energy needed for a muscle to contract, Bailey and his colleagues discovered the beet juice allows the rider to exercise using less oxygen than to usual.
“The beet juice is effective even without any additional training,” said Bailey. “It reduces the need for energy to your muscles so you can last longer.” Whilst beetroot juice was provided free by its manufacturer The University of Exeter paid for the search.
Bailey said that the high nitrate content of beetroot juice is responsible for his sporting achievements. Scientists are not sure how it works, but suspect they have more nitric oxide in the body, a by-product of nitrate, helps you to exercise with less oxygen. Bailey said the same effects could be possible if people consume more foods rich in nitrates, such as beets, lettuce or spinach.
Bailey and his colleagues calculated the beet juice could lead to a race time of 1 to 2 percent better, a little improvement likely that matter to elite athletes. They are still fine-tuning the dosage, but to say athletes should drink the juice of a few hours before training so that their body has time to digest it. Their latest study was published in June in the Journal of Applied Physiology.
“Drinking beet juice does not turn into a recreational runner an Olympic champion, but he could exercise more easier to tolerate for you to train more,” said Dr Andy Franklyn-Miller an expert in sports medicine at the Center for Human Performance in London. It was not related to research and did not receive funding from makers of beet juice.
Franklyn-Miller said, because people often reach a plateau where most sports training is not enough, beet juice might give you an added benefit that you would not get otherwise.
“It is not forbidden, so there’s no reason not to try it,” he said. But he warned too much to drink the juice could lead to side effects such as abdominal cramps, diarrhea or purple urine.
Previous studies in Britain and the United States have found beet helps the heart by lowering blood pressure.
Other experts have warned the handling of your diet cannot replace the benefits of training. “Certain foods can help you maximize the benefits of exercise will not reduce the amount you make,” said Roger Fielding, director of Nutrition, Exercise Physiology and Sarcopenia Laboratory at Tufts University. It was not related to research on sugar beet or any other nutritional supplement.
For serious athletes, Fielding said changing your diet can help. “If a very small improvement is interesting for you, it’s possible something like beet juice could do,” he said.
Other studies have shown things like drinking pickle juice or a snack with carbohydrates during a marathon can prevent cramping and improve performance. The scientists also found the cherry juice, which helps reduce the swelling caused by exercise, could be strong enough to reduce the use of certain drugs athletes against the anti-inflammatory pain.
Fielding said the benefits of beet juice and other foods and beverages could have wider benefits and may one day be used to help older people with weak muscles.
Some elite athletes warned beet juice couldn’t be to everyone’s taste. “Some of my friends think it’s really disgusting,” said Colin McCourt, 25, a British rider will participate in the Commonwealth Games in New Delhi this month.
In April, McCourt began to drink cherry juice and beetroot, which he attributes to help train longer and more often. “I feel like I get an advantage of him, even if it is minimal,” he told Associated Press Television.
McCourt said he will continue to adapt its training program in preparation for the 2012 Olympics in London but plans to maintain its usual juice. “There will be much beet juice if my stomach can take it.”
