Doel van het onderzoek
We hypothesize that dietary nitrate supplementation improves muscle strength and muscle endurance performance.
Onderzoeksopzet
-Exercise testing will be performed after a 6-day supplementation period with beet root juice or placebo.
Onderzoeksproduct en/of interventie
Dietary nitrate will be ingested as beetroot juice. The intervention comprises a 6-day supplementation period with either beetroot juice (140 mL daily) or nitrate-depleted beetroot juice (placebo; 140 mL daily). After ingestion of the last bolus of beetroot or placebo juice, counter movement jump performance, maximal strength and muscular endurance will be assessed. Both experimental periods will be separated by a wash-out period of at least 1 week.
