Psychobiological Exercise Response: A Pilot Investigation of a Laboratory Exercise Assessment Paradigm Among Young Women With Eating Disorders.

ABSTRACT:

Objective

Compulsive exercise is a common feature of eating disorders (EDs) but understanding of factors that drive this symptom remains limited. This pilot trial evaluated psychobiological response to in-laboratory exercise among females (14-22 years) with and without restrictive eating pathology. We aimed to demonstrate the feasibility of two exercise assessment protocols and provide initial estimates of acute exercise effects on affect, body image, and circulating blood-based biomarkers (brain-derived neurotrophic factor [BDNF], cortisol, N-arachodonoylethanolamine [AEA], 2-arachidonoylglycerol [2-AG], leptin).

Method

Twenty females with restrictive EDs and 20 healthy controls completed three study visits, including two bouts of stationary cycling (30-min prescribed pace
