Official title
The Effects of R-1,3-Butanediol With Carbohydrate Supplementation on Cycling Performance Above Lactate Threshold
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to determine whether a ketone supplement with carbohydrates extends time to fatigue during cycling compared with a carbohydrate-only supplement in healthy, trained cyclists aged 18-55. The main questions it aims to answer are: Is the time to fatigue increased with ketone supplementation and carbohydrates compared to carbohydrates alone? Will ketone supplementation with carbohydrates produce lower blood lactate concentrations compared to carbohydrates alone? Participants will: * Perform a staged maximal cycling exercise test on a stationary bicycle. * Finger prick to obtain a drop of blood for lactate measurements. * Wear a mask connected to a metabolic cart to measure breath contents. * Perform a cycling exercise test to fatigue for at least one hour. * Consume either a ketone supplement with carbohydrates or a carbohydrate supplement during the exercise at least 4 times. * Finger prick to obtain a drop of blood to measure blood lactate, ketones, and glucose.
