This study analyzed the effects of 15 days of beetroot juice supplementation on different performance measures in elite Spanish distance runners
This study analyzed the effects of 15 days beetroot juice supplementation on the VO2max, running economy, exercise perceived exertion, muscle power and locomotion mechanics in a group of 12 elite Spanish middle and long distance runners
Exclusion Criteria:
Participants in this group ingested nitrate-rich beetroot juice for 15 days
Dietary Supplement: nitrate-rich beetroot juice
Participants in this group ingested a placebo drink for 15 days
Dietary Supplement: Placebo
Nitrate-rich beetroot juice supplementation was administered for 15 consecutive days to participants in this arm
Also known as: Beetroot juice
Placebo drink
Running economy
The cost of running (oxygen consumption) at different speeds
Time frame: Changes from baseline at 15 days
Time to exhaustion
Time that the athlete endured running until voluntarily ending the exercise
Time frame: Changes from baseline at 15 days
Muscle power
Ability to produce muscle power in a jump test
Time frame: Changes from baseline at 15 days
Muscle oxygenation
Saturation of O2 in the vastus lateralis during exercise
Time frame: Changes from baseline at 15 days
RPE
Rate of perceived exertion during the exercise
Time frame: Changes from baseline at 15 days
