Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study analyzed the effects of 15 days of beetroot juice supplementation on different performance measures in elite Spanish distance runners

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Twelve elite distance runners were randomly assigned to either an intervention group or a placebo group. Participants in each group consumed beetroot juice or a placebo drink for 15 consecutive days.

TRIPLE

Participants Investigators Outcome Assessors
Twelve participants were randomly assigned to either an intervention group or a placebo group, and a 4 digits code based on their Spanish ID card were used to code their names.

Then, an independent researcher prepared individual bags with either a 15-days worth of placebo drinks or beetroot drinks, and gave it to the athletes. Then, this person was withdrawn for the research procedures.

Finally, another group of researchers, without knowing what athlete was on each group (intervention or placebo), conducted the performance tests pre and post 15 days of supplementation, and another group analyzed the data once collected.
