Effects of Nocturnal Inorganic Nitrate Supplementation on Physiological Function

Overview

The purpose of this study is to investigate the effects of acute inorganic nitrate supplementation (with beetroot) on the regulation of sleep and neurovascular physiology.

Interventions

  • Dietary supplement Active Beetroot Juice Supplement (aBRJ)
    aBRJ will consist of 70ml concentrated beetroot juice with 6.45-7.26mmol inorganic nitrate (range for inter-batch variability) taken orally.
  • Dietary supplement Placebo Beetroot Juice Supplement (pBRJ)
    pBRJ will consist of 70ml concentrated beetroot juice and will be chemically devoid of inorganic nitrate taken orally.

Primary outcome measures

  • Change in the amount of time in stage three sleep [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in sleep quality [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in self-reported sleep quality [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in sleepiness [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in daytime sleepiness [Time frame: Baseline, approximately 30 days, and approximately 60 days]
Secondary outcome measures (7)
  • Change in blood pressure [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in sympathetic nerve burst frequency [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in sympathetic nerve burst incidence [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in sympathetic nerve burst amplitude (AU) [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in total muscle sympathetic nerve activity (MSNA) [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in arterial stiffness [Time frame: Baseline, approximately 30 days, and approximately 60 days]
  • Change in endothelial function [Time frame: Baseline, approximately 30 days, and approximately 60 days]
