Nitrate and muscle performance

INTERVENTION: 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. CONDITION: Dietary nitrate, Exercise performance ; ; PRIMARY OUTCOME: ‐Counter movement jump performance ; ; ‐Maximal isometric voluntary contraction; ; ‐Maximal isokinetic voluntary contraction; ; ‐Isokinetic muscle endurance performance; SECONDARY OUTCOME: ‐Plasma nitrate and nitrite INCLUSION CRITERIA: ‐Healthy male ‐Recreationally active (0.5 – 8 h of sport activities per week on a non‐competitive base) ‐18‐40 years
