dietary nitrate, beet root juice, exercise performance, counter movement jump, isokinetic dynamometer
Conditions
Interventions
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 wi
