The aim of this study is to investigate an organic product that has been reported to aid in improving overall exercise performance. Specifically, this study is concerned with examining the effects of tart cherry concentrate ( Prunus Cerasus) on increased exercise performance by increased nitrate production and muscle oxygenation during exercise on a sample of 30 college aged males.
Thirty college-aged men volunteered to participate in this study. Subjects completed three separate visits in which they drank tart cherry concentrate or the placebo two times a day for seven days. The tart cherry concentrate was administered using a single blind randomization and included the tart cherry concentrate 75mg and a placebo 75mg made of an artificial cherry flavored syrup and lemon extract. Participants consumed their respective assigned drink two times a day, and thirty minutes prior to each of their lab visits. Venous blood was drawn and separated following the first consumption of the assigned group and then later frozen and analyzed for total nitrate levels. During the last day of the protocol subjects cycled for 1 hour or until exhaustion at 60% of their baseline VO2 Peak wattage.
The results showed that there was no significant acute difference by treatment for total nitrate level, exercise lactate levels, total hemoglobin, and muscle oxygenation. There was a significant difference by treatment for Respiratory Compensation Point, and baseline VO2 peak values. The results reveal that consumption of tart cherry concentrate provided no 67 increase in serum nitrate levels and muscle oxygenation during exercise. On the basis of the results of this research, it can be concluded that, when consumed in concentrate form, tart cherry concentrate, does not appear to have any direct ability to increase overall exercise performance.
