During exercise, phosphocreatine is used as an energy source, lowering its concentration in the muscles, and vO2 is increased as the lungs take in more oxygen.
During low-intensity exercise, the beetroot juice slowed this reduction in muscle phosphocreatine concentration and the increase in O2. However, during high-intensity exercise, though this effect was still evident, the difference was not large enough to be statistically significant. After drinking beetroot juice, the participants could cycle for longer before feeling exhausted. The researchers conclude that the lower O2 use during exercise in the dietary NO3 supplementation group appears to be due to a reduced use of adenosine triphosphate ATP , a fuel used in muscles.
They observe that this could mean that high-intensity exercise could be tolerated for a longer period. This small experimental study appears to be well designed and reported. There are a few general points to note about this type of study:. Overall, this physiological study in a small group of volunteers will be of interest to sports scientists working in the area. However, this is a small study and, until further research is carried out in larger groups, it does not provide a reason to start drinking beetroot juice to increase stamina.
Accept and close. Food and diet Beetroot juice 'boosts stamina'. Where did the story come from? In the severe cycling test, the loading was increased by 30 watts per minute until the subject could no long continue. After this six-day period, subjects underwent a day 'washout' period during which neither beetroot juice nor cordial were consumed, then the supplement protocol was reversed those who had taken beetroot took cordial and vice-versa.
Throughout this time, all subjects refrained from eating any high-nitrate foods to ensure that any differences were due to the beetroot juice. The beet juice group was able to cycle an average of 16 percent longer. The men also had lower resting blood pressure after consuming the beet juice compared to the currant juice.
The author, Professor Andy Jones, noted: "Our study is the first to show that nitrate-rich food can increase exercise endurance. We were amazed by the effect of beet juice on oxygen uptake because these effects cannot be achieved by any other known means, including training. More Cycling And Nutrition Articles.
