Nitrate and caffeine for exercise performance
Treatments studied
This study tests whether taking beetroot juice (which contains nitrates) and caffeine together can improve performance in high-intensity workouts or swimming. It may help athletes perform better during training or competitions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 45 years old (for the workout group) or 16 to 19 years old (for the swimmer group).
- You have at least 2 years of regular high-intensity workout training (like CrossFit or Hyrox) or 5 years of competitive swimming.
- You train more than 4 times a week (workout group) or swim 8-10 times a week (swimmer group).
- You have no heart, lung, metabolic, or muscle problems that would make high-intensity exercise unsafe.
- You are not allergic to beetroot or caffeine, and you do not take certain medications that could interfere with the study.
- You are willing to avoid supplements, alcohol, and high-nitrate foods for 48 hours before each test session.
