Brief Summary

Several previous studies observed a positive effect of beetroot supplementation on sports performance in athletes, mainly in endurance performance. However, less attention has been paid to its effects on short-duration performance, especially in youth athletes. Moreover, only a few previous investigations performed biochemical analyses, including pro-oxidant balance assessments. It is especially important because chronic nitrate intake might directly cause the production of reactive nitrogen species and reactive oxygen species in other subcellular compartments, leading to more oxidative stress. Additionally, no previous study verified the impact of beetroot intake on sleep.

Group Type: PLACEBO_COMPARATOR

Beetroot juice supplementation or placebo

Intervention Type: DIETARY_SUPPLEMENT

Athletes received 7 days of beetroot juice supplementation with nitrate supplementation (2 × 70 mL of beetroot juice ∼12.9 mmol NO3-; Beet It, James White Drinks, Ipswich, UK) or placebo (2 × 70 mL of water with beetroot powder with negligible nitrate content).

Beetroot group

Athletes received 7 days of beetroot juice (2 × 70 mL of beetroot juice ∼12.9 mmol NO3-; Beet It, James White Drinks, Ipswich, UK).
