Registered report: A pilot investigation of acute exercise response among girls and young women with and without eating disorders.

Driven exercise (DEx) is a serious and common feature of eating disorders (EDs), but current understanding of factors that give rise to and maintain DEx is limited. DEx may be reinforced through its effects on the threat reduction and reward systems. The current protocol is designed to evaluate acute psychobiological response to exercise among female participants (age 16-22) with and without EDs.
