Study Summary
The main purpose of this study is to evaluate the effects of an acute dose of dietary nitrate in the form of beetroot juice on skeletal muscle blood flow in response to dynamic knee extension exercise in healthy older adults. All subjects will receive active (rich in dietary nitrate) or placebo (devoid of nitrate) supplementation.
Primary Outcome
Leg blood flow via Doppler ultrasound examined during dynamic knee extension exercise. Change in blood flow in response to dynamic knee exercise will be measured to examine the influence of dietary nitrate.
