Conn K, Huang K, Gorrell S, Foldi CJ. A transdiagnostic and translational framework for delineating the neuronal mechanisms of compulsive exercise in anorexia nervosa. Int J Eat Disord 2024. [PMID: 38174745 DOI: 10.1002/eat.24130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/21/2023] [Accepted: 12/21/2023] [Indexed: 01/05/2024]
Abstract
OBJECTIVE The development of novel treatments for anorexia nervosa (AN) requires a detailed understanding of the biological underpinnings of specific, commonly occurring symptoms, including compulsive exercise. There is considerable bio-behavioral overlap between AN and obsessive-compulsive disorder (OCD), therefore it is plausible that similar mechanisms underlie compulsive behavior in both populations. While the association between these conditions is widely acknowledged, defining the shared mechanisms for compulsive behavior in AN and OCD requires a novel approach. METHODS We present an argument that a better understanding of the neurobiological mechanisms that underpin compulsive exercise in AN can be achieved in two critical ways. First, by applying a framework of the neuronal control of OCD to exercise behavior in AN, and second, by taking better advantage of the activity-based anorexia (ABA) rodent model to directly test this framework in the context of feeding pathology. RESULTS A cross-disciplinary approach that spans preclinical, neuroimaging, and clinical research as well as compulsive neurocircuitry and behavior can advance our understanding of when, why, and how compulsive exercise develops in the context of AN and provide targets for novel treatment strategies. DISCUSSION In this article, we (i) link the expression of compulsive behavior in AN and OCD via a transition between goal-directed and habitual behavior, (ii) present disrupted cortico-striatal circuitry as a key substrate for the development of compulsive behavior in both conditions, and (iii) highlight the utility of the ABA rodent model to better understand the mechanisms of compulsive behavior relevant to AN. PUBLIC SIGNIFICANCE Individuals with AN who exercise compulsively are at risk of worse health outcomes and have poorer responses to standard treatments. However, when, why, and how compulsive exercise develops in AN remains inadequately understood. Identifying whether the neural circuitry underlying compulsive behavior in OCD also controls hyperactivity in the activity-based anorexia model will aid in the development of novel eating disorder treatment strategies for this high-risk population.

Abstract
PURPOSE OF REVIEW This scoping review aimed to provide a recent update on how to address dysfunctional physical activity and exercise (DEx), and on effects and experiences from including supervised and adapted physical activity or exercise (PAE), during treatment of eating disorders. RECENT FINDINGS A systematic search for peer-reviewed publications in the period 2021-2023 generated 10 original studies and 6 reviews, including one meta-analysis (reporting according to PRISMA and SWiM). Findings showed that DEx was effectively managed by use of psychoeducation and/or PAE. Inclusion of PAE as part of treatment showed low-to-moderate impact on health and positive or neutral effects on eating disorder psychopathology. There were no reports of adverse events. For individuals with anorexia nervosa, PAE improved physical fitness with no influence on body weight or body composition unless progressive resistance training was conducted. For individuals with bulimia nervosa, DEx was reduced simultaneously with increased functional exercise and successful implementation of physical activity recommendations during treatment. Experiences by individuals with eating disorders and clinicians, including accredited exercise physiologists, pointed to positive benefits by including PAE in treatment. SUMMARY Lack of consensus about DEx and of recommendations for PAE in official treatment guidelines hinder adequate approaches to these issues in eating disorder treatment.

[PMID: 37741064 DOI: 10.1016/j.ctcp.2023.101796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 08/04/2023] [Accepted: 08/27/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND Yoga has been recognised as a beneficial adjunct for eating disorder (ED) treatment due to demonstrating positive effects on ED symptomology. Despite this, research exploring the perspectives of clinicians regarding the use of yoga for the spectrum of the EDs is limited. Consequently, this study utilised qualitative enquiry to explore the experiences and perspectives of clinicians regarding the implementation of yoga as an adjunct for ED treatment. This research examines how yoga may be safely applied for the EDs, to enhance ED treatment approaches and recovery. METHODS This study employed semi-structured interviews with 12-clincians with up to 20-years of experience working therapeutically with people with EDs. Participants were asked their perspectives on the benefits, risks, and adaptations for delivering safe and suitable yoga programs for the spectrum of EDs. Template thematic analysis was used. RESULTS Four distinct themes were identified. They included the (1) benefits of yoga, (2) risks associated with the practice, (3) recommendations for adapting yoga for this cohort, and (4) implementing yoga alongside current psychological treatment. CONCLUSIONS Clinicians viewed yoga as a safe and suitable transdiagnostic treatment, with the potential to support individuals with a more holistic and sustained recovery model. Clinicians raised concerns that might arise with the use of yoga for this cohort, however, they also emphasised the ability for these to be mitigated with a series of key adaptations. Importantly, clinicians recommended that yoga is implemented and monitored alongside ED treatment to ensure its suitability and safety. Key barriers for implementing yoga as an adjunct treatment and future research directions are discussed. Recent research has explored the benefits of yoga for individuals with eating disorders (EDs). However, researchers have not yet interviewed clinicians who work with those with EDs regarding their views on using yoga for their clients. This study therefore interviewed 12 clinicians working with individuals with EDs, to obtain their views for using yoga as a therapeutic treatment for this group. Overall, clinicians viewed yoga as a safe and beneficial treatment for EDs. While some concerns were raised regarding the safety of yoga for this group, clinicians emphasised that these could be relieved by a series of key adaptations. This study offers unique insights into how yoga may be safely applied into the care for ED clients, to enhance their treatment approaches and recovery.

Abstract
BACKGROUND While research investigating the potential benefits of yoga for eating disorders (EDs) has expanded, a systematic approach examining how yoga has been implemented for this cohort has not yet been conducted. This research therefore aimed to synthesize the current understanding of how yoga has been implemented for individuals with EDs, with regards to the feasibility, acceptability, and safety of yoga for this cohort. METHODS This study utilised mapping review technology. The following electronic databases were searched within the month of September 2021 and December 2022: PsycINFO, MEDLINE, CINAHL, and Embase. Articles that applied and documented the use of yoga for the EDs were selected. RESULTS The review identified ten unique studies. Details regarding the application, feasibility, acceptability, and safety of these yoga programs were extracted. This resulted in an evidence map or visual summary of how yoga has been applied for the EDs. CONCLUSION While limited, the current literature suggests that yoga is a safe, acceptable, and feasible transdiagnostic intervention for EDs. These findings provide pragmatic support for safely applying yoga for the EDs into clinical practice to support ED recovery.

Int J Eat Disord 2023; 56:1785-1794.

Abstract
OBJECTIVE Previous work has outlined cognitive beliefs about exercise in general, but very little is known about momentary cognitions while engaging in pathological exercise. The primary aim of this study was to explore thought content during exercise and to test whether these thoughts predicted later engagement in eating disorder behaviors. We also tested associations between thoughts and specific exercise activity. METHOD We monitored 31 women with clinically significant eating psychopathology for 3 weeks via ecological momentary assessment as they reported on their exercise and eating disorder behaviors, and thoughts about shape, weight, or calories during exercise. Thoughts were self-reported upon cessation of each exercise session. RESULTS Thinking about weight loss during exercise predicted later engagement in body-checking behaviors. Weight-bearing exercise was associated with a decreased likelihood of thinking about calories but an increased likelihood of thinking about shape during exercise. DISCUSSION These findings show that shape and weight thoughts are present during exercise and that their influence on eating disorder behaviors may exist on a much briefer time scale (i.e., within a day) than previous studies show. Clinically, future studies may seek to test interventions aimed at changing or restructuring cognitions during exercise to help shape adaptive exercise behavior during and after treatment. PUBLIC SIGNIFICANCE This is the first study measuring thoughts during pathological exercise in real-time among those with eating disorder psychopathology. The results show that thinking about weight loss during exercise might increase the likelihood of engaging in body-checking behaviors. Findings will inform the development of treatment approaches to help those in recovery from eating disorders re-engage with exercise.

Abstract
Individuals with eating disorders (ED) experience prolonged malnutrition, binge episodes, and compensatory behaviours that affect every organ system. Psychological and physiological symptoms are worsened with comorbid dysfunctional exercise, seen in up to 80% of those with an ED. Although return to exercise is an important component of treatment and recovery, little is known about the contraindications and risks of exercise engagement specific to those with an ED. This paper provides a comprehensive narrative review of the medical and physiological complications of engaging in exercise during ED treatment and outlines when exercise may be contraindicated or used in modified or cautionary ways. We conducted a literature search on MEDLINE, PubMed, and PsychArticles to identify relevant articles, which yielded six categories of medical and physiological complications of ED that may be exacerbated by exercise: energy availability, cardiovascular health, electrolyte abnormalities, biomedical function markers, sex hormones, and body composition. We summarize the evidence for these complications for readers and offer an initial set of recommendations for incorporating exercise during ED treatment based on our findings. This review may serve as a resource for members of ED treatment teams to help evaluate more readily and confidently whether exercise is safe for individual patients and when modifications and caution may be warranted.

Abstract
PURPOSE Earlier work on engaging in physical exercise when experiencing negative affect demonstrated robust associations with eating disorder (ED) behaviors and attitudes; however, measurement of the behavior was primitive, relying on one yes/no question that cannot capture much variability. We report on the development of a self-report measure, the Reactive Exercise Scale (RES), that disentangles the tendency to engage in exercise in response to negative mood cues from the tendency to engage in exercise in response to eating and body image cues, which themselves may be associated with negative mood. The measure also assesses exercising in response to positive mood cues. METHODS Exploratory factor analysis (EFA) guided item and factor selection. Confirmatory factor analysis (CFA) in an independent sample tested a 3-factor solution-exercising in response to negative mood cues, eating and body image cues, and positive mood cues. Correlations with exercise attitudes, eating disorder and body image attitudes, mood, and personality were used to evaluate construct validity. RESULTS Results supported the 3-factor structure and indicated that exercising in response to negative mood cues may not uniquely relate to most aspects of ED psychopathology when accounting for eating and body image cues, which themselves are associated with negative mood. CONCLUSION The RES captures the tendency to exercise in response to negative mood, positive mood, and eating and body image cues. Together, these constructs allow researchers to examine the unique relations of negative mood cued exercise with ED constructs, while accounting for appearance-related motives for which exercise may also be used. LEVEL OF EVIDENCE Level III: evidence obtained from well-designed cohort or case-control analytic studies.

Abstract
Compulsive exercise is linked with poorer treatment outcomes in people with eating disorder (EDs). High-performance athletes represent a growing and complex subcomponent of the broader ED population, and emergent evidence indicates that different conceptualisations of compulsive exercise are needed in this population. Existing randomised controlled trials in ED populations have demonstrated small treatment effects on compulsive exercise compared with control groups; however, athletes were sparsely sampled across these studies. Thus, the extent to which current treatments for compulsive exercise in EDs are also effective in high-performance athletes is unknown. For this opinion paper, we sought representation from high-performance sports leadership, someone with lived experience of both an ED and high-performance athletics, and ED clinical experts. We discuss the utility of recommending exercise abstinence in ED treatment with athletes, as well as a number of other treatment strategies with some evidence in other contexts for further consideration and research in this population. These include using mindfulness-based interventions as an adjunct to cognitive-behavioural therapies, using wearable technologies and self-reported fatigue to inform training decisions, and incorporating greater exercise variation into training programs. We also offer practical considerations for clinicians seeking to apply foundational elements of cognitive-behavioural interventions (e.g., exposure and response prevention, cognitive restructuring, behavioural experiments) into an ED treatment program for a high-performance athlete. Future research is needed to examine characteristics of pathological compulsive exercise in athletes and whether available treatments are both feasible and effective in the treatment of compulsive exercise in athletes with an ED.

Abstract
Background: Incorporating physical activity (PA) has been a challenge for health care professionals working with anorexia nervosa (AN) patients. This has contributed to partial physical fitness (PFit) recovery that persists after weight restoration. Objective: This cross-sectional study aimed to examine the relationships between PA, sedentary behaviors, PFit, and quality of life (QoL) in a group of adolescents after hospitalization. Methods: QoL, PA, and sedentary behaviors were measured using the Health-Questionnaire Short-Form 36 (SF-36) and accelerometers, while PFit was assessed through cardiorespiratory fitness, body composition (anthropometry), and strength (six repetition maximum) tests in a total of 63 patients. Results: Light-PA (LPA), moderate-PA (MPA), moderate-to-vigorous-PA (MVPA), and relative sedentary time (%ST) did not meet the recommendations (p < 0.001). Only 22% of the patients met MVPA criteria, and ~82% exceeded %ST. SF-36 scores were lower than normative values except the physical component scale. Absolute cardiorespiratory fitness was reduced (p < 0.001) in 84% of the patients, and was positively associated to body weight, body mass index (BMI), circumferences, and muscle areas. Additional positive significant relationships were found between QoL, muscular strength, and body composition, and negative associations between vigorous-to-very vigorous PA and BMI, skinfolds, and percent body fat. Regression analyses revealed lower body strength as an explanatory factor for improved QoL (OR 1.03, 95%CI 1.00−1.07). Conclusions: PFit and QoL scores are poor after hospitalization. LPA, MPA, and MVPA do not meet recommendations. PFit management—with emphasis on improving muscular fitness—may be a valuable strategy for QoL improvement in AN after hospitalization.

Abstract
Including exercise alongside other therapeutic approaches may help to address dysfunctional exercise use and improve eating disorder treatment outcomes. However, traditional treatment teams often lack the expertise needed to safely prescribe exercise. The aims of this study were to explore the perceptions and experiences of Accredited Exercise Physiologists (AEPs) relating to working with clients diagnosed with eating disorders to identify the role they play in the treatment of eating disorders and identify future training needs. Individual semi-structured telephone interviews were conducted with 12 (n = 9 females) AEPs working in the eating disorders field. Thematic analysis was conducted to extract major themes from the interview transcripts. Five major themes were identified: (1) The role of AEPs in the treatment of individuals with eating disorders is comprehensive; (2) Treatment is more effective when all components are addressed; (3) The absence of therapeutic exercise within standard treatment protocols reflects limitations of traditional scope of practice and knowledge about the role of AEPs; (4) Methods of acquiring further knowledge are insufficient for those in current practice; and (5) Accredited comprehensive training is currently unavailable but needed. This qualitative study showed that AEPs believe they can play a major role in the treatment of eating disorders and that treatment outcomes for individuals are likely to be greatly enhanced when dysfunctional exercise is addressed. Multidisciplinary training is needed.

Abstract
Accumulating evidence suggests that supervised and adapted physical activity provides cognitive benefits for individuals with eating disorders (EDs). The mechanisms underlying the benefits of physical activity are poorly understood. Addressing this knowledge gap may inform the appropriate integration of structured physical activity into eating disorders treatment and recovery. We draw attention to recent findings in the study of the impact of physical activity on the brain, and we describe the neurostructural and neurocognitive changes associated with physical activity observed in various clinical and nonclinical populations. Considering the identified impairment in brain volume- and/or neurocognitive function in various EDs, we propose that positive effects of physical activity may play a meaningful role in successful ED treatment. Accordingly, we outline research steps for closing the knowledge gap on how physical activity may aid in ED recovery, and emphasize the need to combine measures of cognitive and behavioral responses to physical activity, with technology capable of measuring changes in brain structure and/or function.

Abstract
OBJECTIVE Investigations into online eating disorder (ED) communities have allowed for a rich exploration of lived experiences focused on a number of aspects, such as recovery and support groups. There is a lack of understanding around compulsive exercise (CE), which is often a characterizing condition of EDs. Exploring the lived experiences of CE as discussed online could provide helpful insight towards a better understanding of CE. Therefore, the purpose of this study was to explore experiences around CE and EDs shared on social media sites. METHOD Social media posts related to CE and EDs from Reddit, Twitter, Instagram, and forums were collected for 12 months. A thematic analysis of 881 posts was used to identify common themes among individuals' lived experiences with CE. RESULTS Five themes (and three subthemes) were identified across the social media posts: (1) seeking control, but ultimately CE takes hold, (2) burning off binges, but at what expense?, (3) recovery is a battle, but worth it, (4) is my exercise healthy?, and (5) frustration with comments about CE. DISCUSSION The lived experiences of CE among individuals with EDs have provided support for current definitions of CE and shared novel insight into the recovery experience. Individuals online also highlighted the need for improvement in treatment around CE specifically, and greater awareness around CE for the general public and healthcare providers.

Abstract
OBJECTIVE Although maladaptive exercise (ME) is widely recognized as a clinical feature in transdiagnostic eating disorders, less is known about psychosocial factors that give rise to and perpetuate this behavior. This systematic review aimed to examine the empirical status of this association. METHOD We reviewed 46 full text articles examining longitudinal associations between psychosocial variables and ME. RESULTS Eighteen studies met full inclusion criteria. Based on our qualitative synthesis, evidence suggests reasonably consistent associations between early concern with weight and shape, and negative affect on later development of ME. DISCUSSION Inconsistent and insufficient assessment of ME across a majority of studies underscores caution in interpretation of results, but guides important discussion for future clinical and research efforts.

Depression and physical health as serial mediators between interpersonal problems and binge-eating behavior among hospital nurses in South Korea. Arch Psychiatr Nurs 2021; 35:250-254. [PMID: 33966788 DOI: 10.1016/j.apnu.2021.02.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 08/17/2020] [Accepted: 02/20/2021] [Indexed: 12/19/2022]
Abstract
This cross-sectional study examined the relationship between depression, physical health, interpersonal problems, and binge-eating behavior among South Korean nurses. Self-report questionnaires were answered by 187 nurses from five hospitals. Mediating roles of depression and physical health between interpersonal problems and binge-eating behavior were examined using mediation analyses with bootstrapping. Total and direct effects of interpersonal problems on binge-eating behavior were significant. Indirect effects of path through depression and physical health as mediators, and through single mediation of physical health were significant, while indirect effects through depression were not. Thus, physical health affects nurses' vulnerability to interpersonal problems and binge-eating behavior.

Abstract
Pathological exercise behavior is pervasive in eating disorder psychopathology, yet minimal treatment guidance exists for extinguishing it as little is known about how to differentiate pathological from healthy exercise. The purpose of this study was to characterize pathological exercise in terms of motivation to increase the specificity with which both pathological and healthy exercise is described and to inform treatment interventions. Latent profile analysis characterized homogenous groups based on exercise motivation in two samples: college women (n = 200) and women with eating psychopathology (n = 211). These profiles were compared on levels of eating and general psychopathology and emotion dysregulation. Three profiles emerged describing sedentary, pathological exercise, and athlete groups in the first sample, and five profiles describing neutral, sedentary, weight loss, athlete, and pathological exercise groups emerged in the second sample. Findings indicate that motivation style is salient in defining pathological exercise and may, therefore, be a clinically useful treatment target.

Abstract
Eating disorders (ED) are complex mental illnesses and are not a result of personal choice. Full recovery from an ED is possible. The severity and inherent lethality of an ED is undisputed, and the role of the registered dietitian nutritionist (RDN) is essential. Clinical symptomology presents at varying developmental milestones and is perpetuated through a sociocultural evaluation of beauty and drive for ascetic idealism. ED are globally prevalent in 4.4% of the population aged 5 to 17 years, yet affect individuals across the entire lifespan, including all cultures and genders. The Behavioral Health Nutrition Dietetic Practice Group, along with the Academy of Nutrition and Dietetics Quality Management Committee, revised the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs in Eating Disorders. Including the RDN in ED treatment is vital for all levels of care. The RDN must be perceptive to negative symptoms indicative of psychological triggers when exploring food belief systems, patterns of disinhibition, and nutrition misinformation with clients. Through a conscious awareness of medical, psychological, and behavioral strategies, the implementation of the SOP and SOPP supports a dynamic and holistic view of ED treatment by the RDN. The SOP and SOPP are complementary resources for RDNs and are intended to be used as self-evaluation tools for assuring competent practice in ED and for determining potential education, training, supervision, and mentorship needs for advancement to a higher practice level in a variety of settings.

Abstract
OBJECTIVE Anorexia nervosa (AN) with compulsive exercise is associated with poor treatment outcomes. This study sought to understand the attitudes of adolescents with AN from various stages of treatment, toward physical activity research practices and physical activity as a component of treatment. METHOD Seventeen adolescents 12-18 years old (15 female) with AN (10 with acknowledged history of compulsive exercise) were recruited from a Canadian Tertiary Care Hospital's Eating Disorder Program. Six inpatients, 5-day program patients, and six outpatients treated by either the inpatient and/or day treatment program in the past 2 years completed individual, semi-structured interviews that were audio-recorded and transcribed. Results were analyzed deductively using qualitative techniques. RESULTS Participants recognized both benefits (psychological, sociological, and physiological) and risks (trigger negative thoughts, increase competitive behavior) of implementing physical activity into acute AN treatment. Patient characteristics, such as stage of treatment and exercise history, had an impact on participants' perceptions toward physical activity in AN. Participants suggested that the ideal physical activity program would be focused on fun, individualized and progressively integrated, group-based, and directly supported by staff. Although the majority of participants stated that they would wear an activity monitor for research purposes, concerns were voiced regarding compliance and the potential impact on eating disorder symptomatology. DISCUSSION Participants overwhelmingly supported the careful implementation of structured physical activity and physical activity psychoeducation into the acute treatment of adolescents with AN. This study allows for the inclusion of patient voices in the conversation surrounding the role of physical activity in AN treatment.

Abstract
BACKGROUND Physical activity (PA) is an integral part of healthcare for the general population and individuals with psychiatric disorders. However, PA is significantly more complex for and related to both healthy (e.g., reduced anxiety and depressive symptoms) and unhealthy outcomes (e.g., intrusive, repetitive thoughts that lead to abnormally high levels of PA) among women with an eating disorder (ED). Consequently, many healthcare professionals recommend abstinence from PA during ED treatment. Despite this, women may remain engaged in PA during ED treatment or resume PA shortly thereafter. Little has been done to understand women's PA behaviors and attitudes and to explore how they integrate PA into their lives during and after ED treatment. Thus, this study sought to explore PA behaviors and attitudes among women with an ED. METHODS Nine women who self-reported receiving an ED diagnosis participated in semi-structured interviews, which were transcribed and analysed thematically. RESULTS Six interrelated themes were constructed to represent participants' PA experiences: PA as a lifestyle, PA can be beneficial, How I feel when I can't do PA, Being cautious about PA, Reactions to healthcare professionals' practice of recommending abstinence from PA during ED treatment, and PA programming thoughts. CONCLUSIONS Overcoming dysfunctional PA behaviors (e.g., engaging in abnormally high levels of PA) and attitudes (e.g., associating PA with caloric expenditure) can be a long and complicated journey for women with an ED. Nevertheless, women with an ED want PA to be integrated into their ED treatment protocol for two key reasons, namely to accrue the benefits associated with PA and to learn how to engage in PA in adaptive and healthy ways.

Validation of the Intuitive Exercise Scale in Patients With Eating Disorders. JOURNAL OF CLINICAL SPORT PSYCHOLOGY 2021.

Abstract
Unhealthy cognitive–emotional relationships with exercise can hinder positive treatment outcomes when left unaddressed. However, clinicians lack validated tools to monitor this aspect of treatment. This study examined the 14-item Intuitive Exercise Scale with 165 patients in the United States (Mage = 26.48 years) who were receiving treatment for an eating disorder. The original factor structure was inadequate for the current sample, and exploratory factor analysis generated three factors—emotional exercise, body intuition, and exercise variety. The three-factor solution yielded strong internal consistency and partial support for the scale’s validity. Furthermore, patients scored lowest in body intuition, confirming low awareness of bodily cues common in patients with eating disorders. This study informs how clinicians may integrate and monitor patients’ cognitive–emotional relationship with exercise as part of holistic and intuitive eating disorder treatment approaches.

Abstract
Driven exercise (i.e., feeling compelled to exercise to control one's weight or shape, to obtain other positive consequences of exercising, or to avoid other negative consequences of not exercising) is a common phenomenon in individuals with eating disorders (EDs), typically associated with negative clinical outcomes. Current theoretical models of driven exercise highlight the short-term affect-regulating outcome of acute driven exercise, which is implicated to maintain this symptom either by positive or negative reinforcement. However, few studies have actually investigated cognitive, affective, and psychobiological mechanisms related to acute driven exercise. In particular, experimental studies that directly test mechanisms leading to the short-term affective improvement after acute driven exercise are scarce. In this article, we therefore propose potential cognitive, affective, and psychobiological mechanisms that could explain the affect-regulating function of driven exercise in individuals with EDs. In addition, we suggest examples of experimental studies that could directly test these mechanisms in individuals with EDs, as recent studies have demonstrated the safety of supervised exercise in EDs research. Our aim of stimulating research on the underlying causes and maintenance factors of driven exercise in EDs has the potential to critically inform treatment development for this high-risk population.

Abstract
BACKGROUND AND PURPOSE Anorexia nervosa (AN) becomes chronic, with high physical, psychological and social morbidity and high mortality without early and effective treatment. The impact of physical exercise as a coadjutant to conventional treatment in this clinical population has been studied with favorable results. Although a Pilates program could be beneficial for patients with AN, no study has analyzed its feasibility and effects in adolescents with AN. Therefore, this study evaluated the safety of a Pilates program and investigated the feasibility and effect in adolescents with AN. MATERIALS AND METHODS In this prospective quasi-experimental study, body composition, blood analysis, sedentary time, physical activity and time of sleep, and physical fitness were measured objectively before and after a 10-week Pilates supervised program. RESULTS Twelve female adolescents with AN (14.6 ± 1.7 years old) completed the program, with a session attendance rate of 96%, a persistence rate of 100%. There were significant increases in height, plasma calcium and sleep efficiency. Significant decreases in plasma follitropin, sleep duration and, duration and number of night perturbations were observed. CONCLUSION A Pilates program is safe and feasible in adolescents with AN when they have a controlled and stable weight, and such a program could be a viable alternative among treatment programs to achieve better sleep quality.

Is physical exercise and dietary therapy a feasible alternative to cognitive behavior therapy in treatment of eating disorders? A randomized controlled trial of two group therapies. Int J Eat Disord 2020; 53:574-585.

Abstract
OBJECTIVE To compare effects of physical exercise and dietary therapy (PED-t) to cognitive behavioral therapy (CBT) in treatment of bulimia nervosa (BN) and binge-eating disorder (BED). METHOD The active sample (18-40 years of age) consisted of 76 women in the PED-t condition and 73 in the CBT condition. Participants who chose not to initiate treatment immediately (n = 23) were put on a waiting list. Outcome measures were the eating disorder examination questionnaire (EDE-Q), Clinical Impairment Assessment (CIA), Satisfaction with Life Scale (SWLS), Beck Depression Inventory (BDI), and numbers in remission at posttreatment, and at 6-, 12-, and 24-months follow-up. RESULTS Both treatment conditions produced medium to strong significant improvements on all outcomes with long-term effect. The PED-t produced a faster improvement in EDE-Q and CIA, but these differences vanished at follow-ups. Only PED-t provided improvements in BDI, still with no between-group difference. Totally, 30-50% of participants responded favorable to treatments, with no statistical between-group difference. DISCUSSION Both treatments shared a focus on normalizing eating patterns, correcting basic self-regulatory processes and reducing idealized aesthetic evaluations of self-worth. The results point to the PED-t as an alternative to CBT for BN and BED, although results are limited due to compliance and dropout rates. Replications are needed by independent research groups as well as in more clinical settings.

Abstract
BACKGROUND Dysfunctional thoughts- and use of physical activity (PA) are core symptoms of the eating disorders (ED) bulimia nervosa (BN) and binge eating disorder (BED). The compulsive desire for PA complicates a favourable treatment outcome; hence, regular, adapted PA led by personnel with competence in exercise science is rarely part of treatment of BN and BED. The present study compared cognitive behaviour therapy (CBT) with a new treatment combining physical exercise and dietary therapy (PED-t) with respect to the short- and long-term changes in the level of compulsive exercise and actual level of PA in women with BN or BED. METHODS We enrolled 187 women with BN or BED, aged 18-40 years, with BMI 17.5-35, in an outpatient randomised controlled therapy trial. Participants were randomised to PED-t or CBT, while waitlist participants served as a control group during the treatment period. The treatment covered 16 weeks, with 6- and 12 months follow-up, and outcomes included self-reported compulsive exercise (CE) and objectively measured PA, analysed by linear mixed regression models. RESULTS Both CBT and PED-t reduced CE from baseline (P < 0.01, Hedges g ~ 0.4), but with no difference to control group. Compared to baseline, only PED-t significantly reduced the number of patients who scored above cut-off rating for CE, but with no between-group differences. The proportion of participants complying with the official recommendation for PA neither changed following treatment, nor emerged different between the treatment arms. CONCLUSION Both therapies resulted in significant improvements in compulsive exercise, a change not found in the control group, however there were no between-group differences. The findings are tempered by the low statistical power due to a small control group size. The number of participants complying with the recommendation for PA were stable throughout the study, and no change in total PA was found. Presence and intensity of CE decline with treatment, but a need to increase PA towards healthy levels remains unsolved.
