  • Cardiovascular Abnormalities

Interventions

DIETARY_SUPPLEMENT

Beetroot juice rich in nitrate

The participant will intake beetroot juice rich in NO3 (800mg). Two hours after intake the last bottle of juice, the participants will go to the laboratory for the handgrip and cardiovascular tests evaluation. Before crossover protocol a 7-day washout interval will be given for the purification of the compounds provided by the protocols.
