The Effects of 10-Day Exogenous Ketone Consumption on Repeated Time Trial Running Performances: A Randomized-Control Trial.

Introduction: The effects of ketone salt supplementation on repeated short-distance running time trial (TT) performance in well-trained subjects remain unknown.

Purpose: To determine the effects of 10-day exogenous ketone salt supplementation on two consecutive 800 m running TTs in endurance-trained subjects.

Methods: Male and female subjects were randomly allocated to one of the following groups: Ketone (KET) ( = 16) or placebo (CON) ( = 16) (8 m, 8f per group).
