The main objectives of this systematic review were: (a) to identify which aspects\u2014both symptomatological and physical\u2014improve with the inclusion of PE in the treatment of EDs, and (b) to determine the characteristics that PE should have to improve the identified symptomatology. A literature search was conducted following PRISMA guidelines using the PubMed, Web of Science, PsycINFO, and Scopus databases. Keywords were divided into three groups (Eating disorders; Exercise and treatment; Characteristics of physical activity), and articles published between 2012 and 2022 were reviewed. Of the initial 1,247 results, 20 studies were included in the analysis, 10 of which were randomized controlled trials (RCTs). Improvements were observed in muscle strength, aerobic capacity, BMI, bone density, as well as in ED symptomatology and quality of life. However, due to methodological differences among the exercise programs, it was not possible to determine the specific characteristics responsible for symptom improvement. Further research is needed to determine the frequency, intensity, duration, type, and volume of PE programs.&nbsp;<\/p>\n\n\n <div class=\"tags\"> <p><strong>Keywords:<\/strong> <span>anorexia<\/span>, <span>bulimia<\/span>, <span>exercise treatment<\/span>, <span>intervention<\/span>, <span>physical activity<\/span><\/p> <\/div> \n\n\n\n<h2 class=\"wp-block-heading\"><strong>Introduction&nbsp;<\/strong><\/h2>\n\n\n\n<p>It has been demonstrated that engaging in physical activity (PA) promotes the physical, psychological, and social well-being of participants (<a href=\"#23\" class=\"ek-link\">Gonz\u00e1lez-Peris et al., 2022<\/a>). In recent years, scientific literature has increasingly focused on the therapeutic properties of physical exercise (PE) in addressing mental health issues. Eating disorders (ED), such as anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), or other specified feeding or eating disorders (OSFED), are considered psychiatric conditions characterized by altered eating behaviors that impair health and psychosocial functioning (<a href=\"#23\" class=\"ek-link\">Gonz\u00e1lez-Peris et al., 2022<\/a>). In several manifestations of these ED, patients use PA as a common strategy to lose weight, improve their figure (<a href=\"#41\" class=\"ek-link\">Quiles et al., 2021<\/a>), compensate for or eliminate food intake, or to relieve negative states (anxiety, depression, and stress) and ED symptoms (concern about weight, drive for thinness, body dissatisfaction, and restrictive profiles). However, it has been shown that PE as an adjunctive treatment can have positive effects on the main symptoms of AN, on both physical and mental health, and can promote better engagement with healthcare teams (<a href=\"#41\" class=\"ek-link\">Quiles et al., 2021<\/a>). In fact, the first studies on this topic, conducted by <a href=\"#6\" class=\"ek-link\">Blinder et al. (1970)<\/a> and <a href=\"#5\" class=\"ek-link\">Beaumont et al. (1994)<\/a>, observed improvements in symptomatology after implementing a supervised PE program in groups of patients with EDs. Later research indicated that PE reduced compensatory behaviors and facilitated weight gain in anorexia, decreased drive for thinness, bulimic symptoms, and body dissatisfaction, increased strength levels, reversed cardiac abnormalities in severe anorexia, and improved quality of life (<a href=\"#11\" class=\"ek-link\">Calogero &amp; Pedrotty, 2004<\/a>; <a href=\"#13\" class=\"ek-link\">Cook et al., 2017<\/a>; <a href=\"#19\" class=\"ek-link\">Fern\u00e1ndez-del-Valle et al., 2014)<\/a>.&nbsp;<\/p>\n\n\n\n<p>Interestingly, PE is still rarely used in mental health units as part of ED treatment due to concerns that it might reinforce excessive exercise aimed at achieving the &#8220;ideal body&#8221; (<a href=\"#40\" class=\"ek-link\">Quesnel et al., 2018<\/a>). This is likely due to the absence of clear guidelines on how to manage PE in this context, the lack of standardized protocols guiding professionals on how to use exercise effectively as part of ED treatment, and differing attitudes toward these approaches in clinical settings (<a href=\"#45\" class=\"ek-link\">Fern\u00e1ndez-del-Valle et al., 2014; Toutain et al., 2022<\/a>).&nbsp;<\/p>\n\n\n\n<p>Based on the above, the objectives of this systematic review were: (i) to identify which aspects, both symptom-related and physical fitness-related, improve with the inclusion of PE in the treatment of EDs, and (ii) to determine the characteristics that PE should have in treatment to improve the identified symptomatology.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Methodology<\/strong><\/h2>\n\n\n\n<p>A systematic review of relevant literature was conducted following the PRISMA 2020 statement (<a href=\"#39\" class=\"ek-link\">Page et al., 2021<\/a>).

Pilates, on the other hand, improved sleep quality.<\/p>\n\n\n\n<p>Other studies allowed participants to choose the type of PE they wished to practice (<em>n<\/em>&nbsp;=&nbsp;2; <a href=\"#7\" class=\"ek-link\">Bratland-Sanda &amp; Vrabel, 2018<\/a>; <a href=\"#39\" class=\"ek-link\">Lampe et al., 2022<\/a>). Both reported improvements in ED symptomatology, and one of them also found a reduction in overall psychological distress and a decrease in compulsive PE practice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Discussion&nbsp;<\/strong><\/h2>\n\n\n\n<p>This review provides evidence that physical exercise (PE) can serve as an effective therapeutic tool for patients diagnosed with an eating disorder (ED). It shows that the prescription of PE, when supervised by professionals and implemented by a multidisciplinary team, can be safe and offer multiple benefits for individuals with such disorders (<a href=\"#14\" class=\"ek-link\">Cook et al., 2016<\/a>).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Improvements in ED symptomatology through the inclusion of PE in treatment<\/strong><\/h3>\n\n\n\n<p>A total of 35% of the studies (<em>n<\/em>&nbsp;=&nbsp;7) did not describe the intervention characteristics in sufficient detail (for example, the volume or intensity of PE), providing only general information about the type of PE (e.g., <a href=\"#4\" class=\"ek-link\">Bakland et al., 2019<\/a>; <a href=\"#35\" class=\"ek-link\">Mathisen et al., 2018b<\/a>). Furthermore, the instruments used to assess symptomatology were heterogeneous (e.g., EDE-Q [Eating Disorder Examination Questionnaire], BITE [Bulimic Investigatory Test Edinburgh], BSQ [Body Shape Questionnaire], and semi-structured interviews), as each focused on different dimensions.<\/p>\n\n\n\n<p>In this regard, in the present systematic review, the effectiveness of the interventions could not be determined based on specific improvements in ED symptomatology; it could only be examined according to the degree of adherence and the changes in reported outcomes obtained after the PE program. Nevertheless, even though the efficacy criteria were not standardized, only one study concluded that including PE in the treatment for EDs was not more or equally effective in experimental groups compared to CG (<a href=\"#35\" class=\"ek-link\">Mathisen et al., 2018b<\/a>).&nbsp;<\/p>\n\n\n\n<p>In this case, as the authors themselves point out, the lack of significant differences could be due to the low statistical power resulting from the small sample size and the high dropout rate in the control group. The remaining studies concluded that prescribed exercise provided greater efficacy.&nbsp;<\/p>\n\n\n\n<p>As illustrated in Figure 2, the results indicated both psychological and physical benefits after performing PE as part of ED treatment. Consequently, the findings suggest that PE therapy for patients with EDs (AN, BN, BED, or OSFED) is safe and beneficial for both ED symptomatology and overall physical and mental health, although identifying a single specific type of PE remains challenging (<a href=\"#36\" class=\"ek-link\">Mathisen et al., 2023<\/a>; <a href=\"#46\" class=\"ek-link\">Toutain et al., 2022<\/a>). In this regard, strength training targeting major muscle groups showed significant increases in strength based on the 5RM test after 16 weeks of weight training and the 70% 6RM test after 8 weeks (<a href=\"#9\" class=\"ek-link\">Bratland-Sanda et al., 2018<\/a>; <a href=\"#20\" class=\"ek-link\">Fern\u00e1ndez-del-Valle et al., 2014<\/a>). Previous reviews involving AN patients have also confirmed improvements in muscle strength through PE with resistance training, both with and without weights, after 12 weeks of training, and through bench press and leg press tests following 8 weeks of high-intensity strength training (<a href=\"#38\" class=\"ek-link\">Mi\u00f1ano-Garrido et al., 2022<\/a>).<br>More specifically, <a href=\"#48\" class=\"ek-link\">Vancampfort et al. (2014b)<\/a> concluded that a program combining aerobic and strength-endurance training for patients with AN and BN resulted in increased muscle strength, BMI, and body fat percentage. Similar findings were observed in non-clinical samples. Recent review studies, such as <a href=\"#37\" class=\"ek-link\">Mikkonen et al. (2024)<\/a>, indicate that regular strength and endurance training leads to gains in both strength and endurance capacity in healthy adult women.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"560\" src=\"https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-1024x560.jpg\" alt=\"\" class=\"wp-image-70262\" srcset=\"https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-1024x560.jpg 1024w, https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-300x164.jpg 300w, https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-768x420.jpg 768w, https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-1536x840.jpg 1536w, https:\/\/revista-apunts.com\/wp-content\/uploads\/2025\/12\/FIGURA-2-163-01-ENG-2048x1120.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Synthesis of studies showing improvements in ED symptomatology, body composition, and physical fitness according to the type of PE applied in treatment<\/figcaption><\/figure>\n\n\n\n<p>&nbsp;However, in addition, a combined program including aerobic exercise, yoga, and basic body-awareness therapy in patients with AN and BN promoted reductions in eating disorder symptomatology and depressive symptoms.

It is particularly important to highlight the difficulty and complexity of performing aerobic exercise in patients with AN, since excessively intense activity\u2014especially aerobic modalities such as running or swimming\u2014may be inappropriate for individuals with severe malnutrition due to its high energy expenditure requirements, which could lead to further weight loss or other medical risks (<a href=\"#26\" class=\"ek-link\">Heinl, 2018<\/a>). Moreover, aerobic PE is generally avoided in the care of patients with AN, as they often show a strong drive for physical activity and an inability to remain still\u2014commonly referred to as a &#8220;drive for activity.&#8221;&nbsp;<\/p>\n\n\n\n<p>It should be noted that although, in individuals with an ED, the goal is usually to restore BMI by increasing it, <a href=\"#22\" class=\"ek-link\">Galasso et al. (2018)<\/a> reported an improvement in aerobic capacity but also a reduction in BMI, possibly because the sample consisted of patients diagnosed with BED who presented obesity (BMI \u2265 30). Similarly, <a href=\"#33\" class=\"ek-link\">Mart\u00ednez-S\u00e1nchez et al. (2020)<\/a> found no changes in body composition or physical condition after the Pilates program, although they did observe a slight increase in BMI percentile among women with higher weight. This was likely because the participants were adolescents and possibly in a period of restoration and stabilization of body composition, so Pilates helped maintain this stability. In fact, <a href=\"#28\" class=\"ek-link\">Kibar et al. (2016)<\/a> found that an 8-week Pilates program in healthy women had beneficial effects on muscle strength (abdominal and lumbar), as well as on static balance and flexibility. It should also be noted that the present review did not identify physical changes after Pilates or yoga interventions, as the variables evaluated in these studies focused on behavioral aspects rather than physical condition (<a href=\"#10\" class=\"ek-link\">Brennan et al., 2020<\/a>; <a href=\"#16\" class=\"ek-link\">Diers et al., 2020<\/a>).&nbsp;<\/p>\n\n\n\n<p>At the physiological level, as in healthy women (<a href=\"#27\" class=\"ek-link\">Hsu et al., 2024<\/a>), PE was also found to improve bone health in women with EDs, who often show low bone mineral density (BMD), deteriorated bone structure, and reduced bone strength (<a href=\"#9\" class=\"ek-link\">Bratland-Sanda et al., 2018;<\/a> <a href=\"#35\" class=\"ek-link\">Mathisen et al., 2018b<\/a>)\u2014effects that may be further worsened by the negative influence of antidepressants (<a href=\"#17\" class=\"ek-link\">DiVasta et al., 2017<\/a>). It will be important to take BMD values into account, as low levels increase the risk of osteoporosis and, consequently, the likelihood of experiencing pain and fractures in adulthood (<a href=\"#31\" class=\"ek-link\">Lopes et al., 2022<\/a>).&nbsp;<\/p>\n\n\n\n<p>Among the experimental studies in this review, a reduction was recorded in compulsive exercise, the drive for thinness, and bulimic symptoms in ED patients who engaged in PE. Improvements were also observed in body satisfaction (<a href=\"#4\" class=\"ek-link\">Bakland et al., 2019<\/a>; <a href=\"#7\" class=\"ek-link\">Bratland-Sanda &amp; Vrabel, 2018<\/a>; <a href=\"#16\" class=\"ek-link\">Diers et al., 2020<\/a>), as well as in mood, quality of life, and well-being (<a href=\"#3\" class=\"ek-link\">Agne et al., 2022<\/a>; <a href=\"#4\" class=\"ek-link\">Bakland et al., 2019<\/a>; <a href=\"#10\" class=\"ek-link\">Brennan et al., 2020<\/a>; <a href=\"#47\" class=\"ek-link\">Vancampfort et al., 2014a<\/a>). The mental benefits and improvements in pathological behaviors related to CE reported by <a href=\"#4\" class=\"ek-link\">Bakland et al. (2019)<\/a> and <a href=\"#35\" class=\"ek-link\">Mathisen et al. (2018b)<\/a> were likely due to the fact that therapeutic exercise treatment can help reduce patients\u2019 anxiety and &#8220;drive for thinness,&#8221; decrease compulsive engagement in exercise, provide enjoyment, and contribute to better mood and body image (<a href=\"#13\" class=\"ek-link\">Cook et al., 2011<\/a>; <a href=\"#48\" class=\"ek-link\">Vancampfort et al., 2014b<\/a>).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Characteristics of PE for improving ED symptomatology in treatment<\/strong><\/h3>\n\n\n\n<p>This review revealed substantial variability and a lack of systematization in PE prescription\u2014similar to the findings of the systematic review by <a href=\"#39\" class=\"ek-link\">Moola et al. (2013)<\/a>\u2014making it difficult to determine specific characteristics or guidelines for incorporating PE into ED treatment.&nbsp;<\/p>\n\n\n\n<p>Focusing on training variables, and specifically on external load, these were heterogeneous. Regarding intensity and volume in strength training, most programs applied moderate loads (around 50% of 1RM or 70% of 6RM, with 6\u201315 repetitions and 1\u20135 sets; <a href=\"#3\" class=\"ek-link\">Agne et al., 2022<\/a>; <a href=\"#18\" class=\"ek-link\">Fern\u00e1ndez-del-Valle et al., 2015a<\/a>). For strength-endurance training, loads were not specified (<a href=\"#35\" class=\"ek-link\">Mathisen et al., 2018b<\/a>), while for range-of-motion exercises, work durations of 15\u201360 seconds and 2\u20134 sets were reported (<a href=\"#15\" class=\"ek-link\">Dauty et al., 2022<\/a>; <a href=\"#21\" class=\"ek-link\">Fisher &amp; Schenkman, 2012<\/a>). On the other hand, similarities were found in the strength exercises included, as most involved multi-joint movements and large muscle groups (e.g., seated row, bench press, leg press, leg extension, lat pulldown, trunk curl, back extension, and push-ups; <a href=\"#9\" class=\"ek-link\">Bratland-Sanda et al., 2018<\/a>; <a href=\"#18\" class=\"ek-link\">Fern\u00e1ndez-del-Valle et al., 2015a<\/a>). As for aerobic activity, the interventions were much more diverse, both in activity type (e.g., varied sports; Dauty et al., 2022) and in structure\u2014pyramidal intervals (Bakland et al., 2019), high-intensity intervals (Mathisen et al., 2018b)\u2014and in external load. Despite this heterogeneity, the programs produced beneficial effects.&nbsp;<\/p>\n\n\n\n<p><a href=\"#14\" class=\"ek-link\">Cook et al. (2016)<\/a> concluded that tailoring the exercise mode to individual needs is one of the most therapeutically important principles. Therefore, applying the principle of individualization is key, including the type of exercise itself. In this sense, authors such as <a href=\"#7\" class=\"ek-link\">Bratland-Sanda and Vrabel (2018)<\/a>, <a href=\"#29\" class=\"ek-link\">Lampe et al. (2022)<\/a>, or <a href=\"#47\" class=\"ek-link\">Vancampfort et al. (2014a)<\/a> allowed participants to choose their preferred activity type and found improvements in ED psychopathology and quality of life, likely due to increased motivation to engage in enjoyable activities. It is important to note that factors such as enjoyment, motivation, choice, social interaction, and sense of belonging (<a href=\"#49\" class=\"ek-link\">White et al., 2018<\/a>) also influence the relationship between physical activity and mental health.&nbsp;<\/p>\n\n\n\n<p>On the other hand, mind-body interventions (e.g., pilates or yoga) have also been used as treatment in EDs, as they appear to positively influence body image and reduce ED symptomatology (<a href=\"#25\" class=\"ek-link\">Hall et al., 2016<\/a>; <a href=\"#47\" class=\"ek-link\">Vancampfort et al., 2014a<\/a>). In fact, <a href=\"#45\" class=\"ek-link\">S\u00e1nchez and Mungu\u00eda-Izquierdo (2017)<\/a> stated that yoga has the potential to promote body self-awareness\u2014that is, the ability to experience the body from within through meditation, physical movement, and breathing.&nbsp;<\/p>\n\n\n\n<p>The heterogeneity of PE characteristics identified in this review may also be explained by the inclusion of various ED diagnoses (AN, BN, OSFED, and BED), unlike previous reviews that focused on a single manifestation (<a href=\"#46\" class=\"ek-link\">Toutain et al., 2022<\/a>). The spectrum of eating-related behavior differs depending on diagnosis, suggesting that each ED type requires a specific exercise prescription adapted to its particularities.&nbsp;<\/p>\n\n\n\n<p>Given all the above and the difficulty of determining common PE guidelines for ED patients, it is proposed that before initiating exercise in these individuals, it is necessary to reconsider what physical activity means to them, as the personal meaning of PE must change (<a href=\"#14\" class=\"ek-link\">Cook et al., 2016<\/a>). The goal is not to eliminate exercise from daily life but to educate the person to understand movement as a complement to psychotherapy or nutrition. Thus, when individuals return to the gym or resume PE after recovery, they will perceive the activity as enjoyable and healthy. If this shift in perspective is not addressed, there is also a risk that the ED may become chronic (<a href=\"#44\" class=\"ek-link\">Rizk et al., 2020<\/a>) or that maladaptive exercise patterns may increase the risk of injury. For these reasons, and as a final conclusion, PE should not be withdrawn from ED patients but rather adapted and ensured to be carried out under supervision and with the approval of both a therapist and a qualified exercise professional.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Limitations<\/strong><\/h2>\n\n\n\n<p>Despite the contributions of the present work, some limitations should be mentioned. On the one hand, in some cases the studies did not specify what type of stimuli were used or provided little detail regarding the training variables applied to the patient. On the other hand, the heterogeneity of the interventions in terms of analyzed variables, content, duration, and assessment timing made it difficult to compare the results among studies, highlighting the need for further research. Likewise, in order to obtain a substantial number of articles for the review, studies with different methodological designs were included, many of them with limited sample sizes and heterogeneous use of assessment measures and instruments.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusions&nbsp;<\/strong><\/h2>\n\n\n\n<p>This systematic review summarizes the evidence that participation in structured PE programs (aerobic endurance, muscle strength, strength-endurance, or yoga exercises) can be highly beneficial for this clinical population, as it reduces ED symptomatology, improves quality of life and psychological well-being, increases muscle strength and cardiorespiratory capacity, and enhances BMD and anthropometric measures. However, there is still insufficient research to develop a systematic and standardized methodology for prescribing PE as an adjunctive treatment for EDs. Moreover, the inclusion of various ED manifestations in this review made it difficult to identify specific and common guidelines, since each type presents unique nuances and characteristics. For this reason, in future work we aim to analyze and detail the reviewed studies individually, focusing on the similarities according to the type of ED, specifically AN, BN, and BED.<\/p>\n\n\n\n<p>Along the same lines, this also makes it difficult to determine the specific characteristics that PE should have for this population. It has been shown that structured PE programs\u2014including aerobic endurance, muscle strength, strength-endurance, or yoga exercises\u2014significantly improve symptomatology. In general terms, the interventions that have improved the physical or mental symptomatology of individuals diagnosed with EDs are based on the use of light to moderate loads, both for strength and for aerobic endurance, progressively increased while respecting the principle of individualization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Acknowledgements<\/strong><\/h2>\n\n\n\n<p>This work has been carried out thanks to the project PID2019-107473RB-C2 of the Ministry of Science, Innovation and Universities of the Government of Spain and thanks to the project 2021SGR-00806 of the Government of Catalonia.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract This systematic review aimed to identify the interventions carried out to date to assess the effectiveness of physical exercise (PE) as an adjunctive treatment for eating disorders (EDs).
