The same researchers previously conducted a study which examined the possibility beetroot juice can help to increase physical insurance
All of those who took part in the first study were male and aged between 19 and 38. The participants were asked to drink 500ml of beetroot juice every day for a week and the results found that doing this enabled them to cycle for an additional 16 per cent without feeling tired.
The new research found that the juice doubled the levels of nitrate in the blood of volunteers and also helped to reduced the speed at which muscles soaked up energy from their main source, resulting in an increased efficiency of muscles.
Experts believe that the reason for this is down to an ingredient present in beetroot juice. Nitrate leads to heightened levels of nitric oxide in the body which affects blood flow, hormone levels and cell signaling.
Study leader, Professor Andy Jones from the University of Exeter’s School of Sport and Health Sciences, said: “We have seen growing interest in the benefits of drinking beetroot juice in the world of professional sport and I expect this study to attract even more attention from athletes.”
