NCT02579018

Brief Summary

There are two major goals of this investigation. First, to develop pilot data to justify a larger randomized clinical trial of an intervention designed to train interoceptive signals (IS) and interoceptive responsivity (IR) in persons with Anorexia Nervosa (AN). Second, the investigators will determine whether persons with AN have similar or different IS and IR for heart rate while exercising as compared to age and gender matched controls.

Outcome Measures

Primary Outcomes (1)

  • Mean percentage of time in prescribed heart rate range during four bouts of interval exercise training

    One exercise training session

    Baseline only

Study Arms (3)

Anorexia Nervosa (AN)

EXPERIMENTAL

Diagnosis of anorexia spectrum disorder and stable use of all medications ≥ three months.

Behavioral: One hour supervised exercise session

Matched Controls

EXPERIMENTAL

No diagnosis of anorexia spectrum disorder. Stable use of all medications ≥ three months. Also age (+/- 2 years) and gender matched to AN study participant and exercise regularly.

Behavioral: One hour supervised exercise session

Healthy Controls

EXPERIMENTAL

No diagnosis of anorexia spectrum disorder. Stable use of all medications ≥ three months. Do not exercise regularly.

Behavioral: One hour supervised exercise session

Interventions

All participants will participate in a one hour supervised exercise session. Participants will wear a physical activity monitor during the assessment for continuous monitoring of heart rate. Short, intense bouts of exercise will be interspersed with rest periods.
