Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental (Beetroot juice NO3)
8-day supplementation with beetroot juice rich in NO3 (400mg) during 8 days.
Beetroot juice rich in nitrate
The participant will intake beetroot juice rich in NO3 (400mg) during 8-days. On the eighth day of the intervention, 2 hours after intake the last bottle of juice, the participants will return to the laboratory for the performance 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)
8-day supplementation with beetroot juice NO3 depleted during 8 days.
Beetroot juice NO3 depleted
The participant will intake beetroot juice depleted in NO3. On the eighth day of the intervention, 2 hours after intake the last bottle of juice, the participants will to the laboratory for the performance tests evaluation. Before crossover protocol a 7-day washout interval will be given for the purification of the compounds provided by the protocols.
