Abstract
Research has shown that acute supplementation with dietary nitrate will increase the amount of circulating nitrate, boosting NO bioavailability via the nitrate-nitrite-NO pathway, providing enhanced vasodilation. There are limited dietary nitrate studies including young, healthy female participants. The purpose of this study was to investigate the influence of acute dietary nitrate, via beet root juice (BRJ) supplementation, on resting heart rate and blood pressure in young, healthy women. A total of 11 women (aged 18-22) performed a repeated-measures, placebo-controlled, counter-balanced, crossover design investigated the impact of dietary nitrate on the cardiovascular system’s resting measurements after one hour. All participants completed one familiarization and two testing visits that differed in the beverage consumed; beverages include active dietary nitrate BRJ and the Placebo which had dietary nitrate removed by the manufacturer. Two-way, repeated-measures ANOVAs (2 x 2; Time x Treatment) were used to explore mean differences in dependent variables – heart rate, mean arterial pressure, systolic blood pressure, and diastolic blood pressure (HR, MAP, SBP, and DBP). There was no interaction (Time x Treatment) for any dependent variables (all p > 0.540) for HR, SBP, DBP, or MAP. In conclusion, BRJ did not influence resting cardiovascular measurements when compared to Placebo in this sample.
