Ketone Esters and Metabolism During Recovery from Endurance Exercise

Effect of Ketone Esters Ingested During Recovery on Metabolism and Subsequent Exercise Capacity

Infusion of beta-hydroxybutyrate can suppress endogenous glucose production, which may result in increased net liver glycogen storage. If ketone esters exert similar effects, then the increase in liver glycogen storage may have implication for recovery from exercise and subsequent exercise performance.

The aim of this study is to assess the effects of ketone esters ingested during recovery from exercise, on metabolism and subsequent exercise capacity.
