Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental (Beetroot juice NO3)
Acute ingestion of beetroot juice rich in NO3 (800mg).
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.
Placebo (Beetroot juice without NO3)
Acute ingestion of beetroot juice rich depleted in NO3.
Beetroot juice depleted in nitrate
The participant will intake beetroot juice depleted in NO3. 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.
