Exercise Program in Patients With Anorexia Nervosa (ESATRAL) (ESATRAL)

Impact of a Supervised Physical Exercise Program (ESATRAL) in Patients With Anorexia Nervosa After Hospital Discharge

Excessive physical exercise is one of the main symptoms of anorexia and a common restrictive behavior used by patients, which is associated with less short- and long-term treatment success. Supervised exercise has shown these benefits in patients with anorexia: opportunity to learn and acquire knowledge and information on how to perform physical activity in a healthy, safe and moderate way, less feelings of incapacity; lower risk of relapse; prohibiting exercise during treatment can increase the likelihood that patients will revert to old patterns once therapy is completed. Exercise can be as effective as antidepressants and psychological therapies to treat some cases of depression present in anorexia.

The objective of the ESATRAL program is to analyze the physiological, psychological, body composition, physical condition and functionality effects of a supervised strength-focused training program in patients with anorexia nervosa after hospital discharge. All participants are assessed at baseline, after 12 weeks, post-treatment (24 weeks), and at 9 months' post follow-up (36 weeks).

Study Overview

• Status: Withdrawn
• Conditions: Anorexia
• Intervention / Treatment: Other: Exercise Program focused on resistance training

Detailed Description

Experts in eating disorders recommend restricting exercise until the person is medically stable, of sufficient weight and able to compensate exercise with sufficient energy intake. In this sense, a reintroduction and promotion of healthy exercise should be done in a graded and supervised manner, where exercise would provide great benefits, such as improving social confidence and providing a tool for healthy living. That is the goal of the ESATRAL (EXCERCISE AND HEALTH IN EATING DISSORDERS) program. The relationship between eating disorders (ED) and exercise has been controversial, but different studies have already shown that the therapeutic use of exercise in the treatment could be positive if used as a tool for healthy living. Historically in the literature, exercise in anorexia has been mainly considered as a problematic activity that should be limited or even completely forbidden, especially during the acute phase of the disorder, but different researchers have already questioned the restriction-based approach to exercise and investigated its potentially healthy role in recovery. It should also be noted that restricting physical activity can have detrimental musculoskeletal and cardiometabolic consequences for patients with anorexia. In addition to experiencing significant strength losses and atrophy of type II muscle fibers, the loss of lean tissue affects organ mass and function in these patients. Lean body mass-comprised of visceral organs such as the liver and heart, as well as bone and skeletal muscle-plays an important role in setting the demand for energy metabolism. Patients with anorexia present with a number of characteristic metabolic and endocrine disorders as a result of chronic malnutrition that affect lean tissue. ESATRAL is a supervised physical exercise program that is implemented in patients with anorexia nervosa after hospital discharge. ESATRAL consists of three days of weekly strength training that will be measured following the strength-velocity methodology. The objective of the ESATRAL program is to analyze the physiological, psychological, body composition, physical condition and functionality effects of a supervised strength-focused training program (6 month duration) in patients with anorexia nervosa after hospital discharge. The risk of relapse is an obstacle that can be minimized if supervised exercise were included in the treatment of anorexia as is done in ESATRAL. Many patients engage in excessive and unsupervised exercise, and returning to this level of physical activity after treatment has been associated with an increased risk of relapse. Therefore, prohibiting exercise during treatment may increase the likelihood that patients will fall back into old patterns after treatment ends, hence the importance of ESATRAL.

The ESATRAL project will compare the effects of supervised strength training as a part of the treatment vs. treatment without supervised strength training, in patients with Anorexia nervosa after hospital discharge. All participants will be assessed at baseline, after 12 weeks, post-treatment (24 weeks), and at 9 months' post follow-up (36 weeks). .

The study will be conducted with ITA- PREVI patients at the PERFORMA personal training health center in Valencia.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: ESATRAL Group; They will perform the supervised physical exercise program. The supervised exercise program (ESATRAL) will last 24 weeks with 2-3 non-consecutive weekly sessions. The duration of each session will be 30 minutes and will progressively increase depending on the phase in which we are until reaching 60 minutes.	Other: Exercise Program focused on resistance training; The program will be carried out by a personal trainer. To ensure correct execution, given that the groups will be of a maximum of 5 people. Each session will include: A) Warm up: movility exercises and coordination games B) Main part: 3 exercises will be included to strengthen different muscle groups (pull , bench press and back squat). Velocity based training (VBT) will be used to control load. 3 sets of 16-30 repetitions mantaining the speed between Light (estimated loss of speed of the series 5-10%). C) Cool down: feedback with patients based on the work of Stiles-Shields (2015). Specific training content will focus on safety, while re-educating patients on proper exercise methods, motivation-related attitudes, and transparency on health benefits and potential harms as a result of increased exercise.
No Intervention: Control Group; They will follow their daily treatment without added exercise

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in Risk of eating disorders	The Eating Disorder Inventory-3 will be used. It made up of 91 items organized into 12 subscales (3 specific to eating disorders and 9 general psychological scales). It uses a 0-4 point scoring system.

Demographic variables	The following demographic variables will be taken to characterize the sample: Age, type of anorexia (diagnosed in the Hospital), time of evolution of the disease and BMI (BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared).	Base line, week 12, week 24, week 36
Changes in perceived quality of life	Difference in quality of life measured with SF-12v2 (Ware et al., 2009) in patients treated with standard treatment compared to patients treated with ESATRAL. Scoring is on a scale from 0 to 100 where higher score means a better perceived state of health.	Base line, week 12, week 24, week 36
Changes in eating attitudes	Difference in attitudes towards food measured with EAT-26 (Garner et al., 1982) in patients treated with standard treatment compared to patients treated with ESATRAL. Scoring is on a scale from 0 to 78. Higher scores indicate greater risk of an eating disorder and total scores 20 or above are considered to be in the clinical range.	Base line, week 12, week 24, week 36
Changes in compulsive exercise	Difference in compulsive exercise measured with Compulsive Exercise test (CET) in patients treated with standard treatment compared to patients treated with ESATRAL. Scoring is measured on a scale from 0 to 5 where higher score means a worse outcome except for two questions where higher score means better outcome.	Base line, week 12, week 24, week 36
Changes in body image	Difference in body image measured through the Multidimensional Body Self Relations Questionnaire (MBSRQ) (Cash, 2000) in patients treated with standard treatment compared to patients treated with ESATRAL.
