What is this trial about?

Diet can alter blood ketone levels and this in turn may affect exercise capacity. This study will determine if the acute ingestion of a ketone supplement alters cycling time trial performance. Participants will perform two trials in a randomized order. Each trial will involve a 20-minute bout of cycling on a stationary ergometer. Participants will ingest either a ketone supplement or a taste-matched placebo drink prior to exercise. Blood samples will be obtained to assess selected metabolic responses. This study will provide information regarding the effect of ketone supplementation on exercise responses.

What are the participation requirements?

Yes
