This study; In the elite of the athletes, the effect of single dose of beetroot juice was made to investigate the on some performance parameters. In this study, two measurements were applied to the same athletes as beetroot juice (similar to 8.4 mmol NO3-) and placebo. Following the assessment, 10 athletes from 25-31 years of age were included in the study. The study was planned double blind. The athletes started the test at 0% tilt on the treadmill, at a speed of 8 km/h, and 3 minutes later, the speed was increased to 10 km/h. After a speed of 10 km/h every three minutes, the speed of the athlete's test continued to increase by 1 km/h after speed of 2 km/h, 18 km/h. The athletes were taken to the test and were rested for 1 minute before each speed increase and blood was obtained from the earlobes. During the test, lactate values, heart rate numbers and respiratory parameters were recorded. The group's differences between measurements were examined using the ' Wilcoxon sign ' test. At the end of the work; In the measurements that correspond to running speeds up to 20 km/h of the measurements used in beet water, VO2/kg and VO2 values are statistically significant differences in the running speed and total performance time compared to the lactate threshold, according to the placebo measurement (P<0.05). As a result, the use of acute beetroot juice in a single dose is positively effective on oxygen consumption and performance, the maximum oxygen consumption, heart rate, lactate, anaerobic threshold heart rate and anaerobic threshold do not affect the values of oxygen consumption was detected.
