THE EFFECT OF FRACTIONATED RED BEETROOT JUICE ON PERFORMANCE AND OVERALL HEALTH OF A HIGH-PERFORMANCE ATHLETES

Over the past 20 years, nitric oxide has become the turning point in athlete physiologyand medical research. It has been observed in scientific studies that there are very differentprotocols for the use of nitrates (red beetrootjuice) and different research methodology andresults. The most effective solutions for improving the performance of athletes are still beingsought. The purpose of this research is to investigate the performance and overall health of a high-performance athlete after consuming fractionated red beetrootjuice. The investigation is a one-case study. The respondent is a high-class athlete - trackand field (middle and longdistance),20 years old. Three tests were performed in laboratory conditions with an intervalof oneweek. The first test was without the use of fractionated red beetrootjuice, the second testafter a single dose, and the third after 7 days of use. The research used an interview of therespondent, cardio pulmonary exercise testing measuring device "Vyntus CPX" with gasanalysis on a bikeergometer and determination of blood lactate concentration. In theexperiment, the athlete's VO2max improved during each test, after one dose by 9%, and after7 days of use by 13% from the first test. The physical overall health at the end of the testworsened each time, but in the previous tests, where fractionated red beetrootjuice was used, a faster recovery of the athlete'sworking capacity after exercise was observed
