Nitrate and caffeine for athletic performance
Treatments studied
This study tests whether taking nitrate (from beetroot) and caffeine together can improve performance in high-intensity workouts or swimming. It may help athletes who train hard and compete regularly.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 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) and train more than 4 times a week, or you are a competitive junior swimmer on the Polish national team.
- You have a medical certificate that says you can compete in sports.
- You have no heart, lung, metabolic, or muscle problems that would make high-intensity exercise or stimulants unsafe.
- You have no allergies to beetroot or caffeine, and you are not taking certain medications (like proton pump inhibitors or antibiotics).
- You are willing to avoid supplements, alcohol, and high-nitrate foods for 48 hours before each test.

This study tests whether adding a natural nitrate supplement to a supervised exercise program can boost the health benefits of exercise in older adults. It will compare exercise plus supplement versus exercise plus placebo to see which improves fitness and heart health more.
This study tests whether a single dose of a beetroot-like concentrate (betalain-rich) can help you sprint faster on a bike and recover better between repeats. It's for healthy, active adults who want to see if a natural supplement boosts performance.
This study looks at whether a natural supplement from beetroot (inorganic nitrate) helps lower blood pressure after exercise in people who are obese and have slightly high blood pressure. Participants will take the supplement or a placebo and do supervised cycling sessions.
