This study is looking at whether a drink containing a ketone supplement called R-1,3-Butanediol along with carbohydrates can help highly trained cyclists cycle longer before getting tired, compared to a drink with only carbohydrates. Researchers want to see if this combination increases the time you can cycle and if it leads to lower levels of lactate (a substance that builds up in your muscles during exercise) in your blood. You might be able to join if you are a healthy male or female cyclist between 18 and 55 years old, train at least six hours a week, and do not have certain health conditions like heart or lung disease. The study plans to enroll 15 participants and is currently unclear on its recruitment status.

Study design

This is an interventional study, meaning participants will receive specific treatments. It aims to enroll 15 highly trained cyclists.

What's involved

You will have three visits, each lasting about one hour and spaced at least 7 days apart. These visits will include a maximal cycling exercise test, finger pricks for blood samples, and wearing a mask to measure your breath.

Compensation

Not stated in the trial record.

Follow-up

Your time to fatigue will be measured through study completion, which is an average of 2 weeks.
