Study Summary

This trial looks at whether beetroot juice can help improve exercise performance in females.

Who is the study for?
This trial is for men and women who are physically active but not highly-trained athletes. They must be in good health, with normal blood pressure (systolic: 120-129, diastolic: 80-84) and a normal BMI range (18.5-24.9). There should be no orthopedic issues that could affect their participation.Check my eligibility
What is being tested?
The study is testing the effects of concentrated beet root juice versus a placebo on exercise efficiency, strength, and fatigue resistance. It aims to understand if there are differences between how males and females respond to dietary nitrate supplementation across the menstrual cycle.See study design
What are the potential side effects?
Beet root juice may cause changes in urine or stool color due to its natural pigments. Other potential side effects include low blood pressure, stomach upset or discomfort.

Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: Dietary nitrateActive Control1 Intervention
The active treatment, beetroot juice (BEET IT, James White Drinks, Ipswich, UK), contains 6.2mmol of inorganic nitrate. Participants will continue supplementation until they complete all testing visits.
Group II: PlaceboPlacebo Group1 Intervention
The placebo beet root juice is made by the same company (BEET IT, James White Drinks, Ipswich, UK) and contains no inorganic nitrate.
