Here, even though both acute and short-term supplementation with nitrate-rich beetroot juice were found to have equally beneficial effects on muscle speed and power in older individuals, no apparent changes in blood pressure or plasma markers of oxidative stress were observed.

- Sixteen community-dwelling older men and women with a mean age of 71 years completed this registered clinical trial.

- The participants not on the placebo group drank 140 mL of concentrated beetroot juice containing (based on direct measurement) 18.2±6.2 of NO3-.

- Compared to baseline, similar increases in maximal knee extensor speed and power were observed after both acute and short-term (2 weeks of daily supplementation) ingestion of beetroot juice containing NO3-.

- On the other hand, neither acute nor short-term (2 weeks of daily supplementation) beetroot juice supplementation, either with or without NO3- had any statistically significant effect on blood pressure or on plasma markers of oxidative stress.

Short-term beetroot juice supplementation improves muscle speed and power but does not reduce blood pressure or oxidative stress in 65–79 y old men and women
