How to address physical activity and exercise during treatment from eating disorders: a scoping review

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.publishedVersio

Affective Responses to Repeated Endurance Training Sessions with Different Intensities: A Randomized Trial

International Journal of Exercise Science 15(5): 152-165, 2022. The purpose was to examine differences in affective responses to repeated sessions of endurance training with different intensities in healthy adults. Thirty young, healthy, and recreationally physically active adults (50% women, age 24.4 ± 6.0 years, VO2max 48.6 ± 7.4 ml-1×kg-1×min-1, BMI 23.5 ± 2.4 kg×m2) performed a VO2maxtest. They were randomized to four sessions of either high intensity sprint interval training (SPRINT, n=10, 5 × 30-sec at \u3e95 of HRpeak, 4-min recovery between intervals), high intensity aerobic interval training (HAIT, n=10, 4 × 4-min at ~90% of HRpeak, 4-min recovery between intervals) or moderate intensity continuous training (MIT, n=10, 50-min at ~75% HRpeak). Assessment during and after each session included HR, La-, Borg ratings of perceived exertion (RPE), affective state (positive/negative), valence (pleasure/displeasure), arousal (calmness/excitement), tension, irritation, pain, exhaustion, satisfaction, and motivation. HR, La- and Borg RPE were higher in SPRINT and HAIT compared to MIT (p \u3c 0.001), no differences between SPRINT and HAIT. Displeasure and arousal were greater in SPRINT compared to HAIT (p \u3c 0.05) and MIT (p \u3c 0.001). Within each session, between-group effects showed that SPRINT differed from HAIT and MIT on valence (p \u3c 0.01) and arousal (p \u3c 0.01), and MIT differed from HAIT and SPRINT on La- (p \u3c 0.001) and HR (p \u3c 0.001). In conclusion, repeated sessions of HAIT produced similar physiological responses as SPRINT, and similar affective responses as MIT

The neurostructural and neurocognitive effects of physical activity: A potential benefit to promote eating disorder recovery.

Accumulating evidence suggests that supervised and adapted physical activity pro-vides cognitive benefits for individuals with eating disorders (EDs). The mechanismsunderlying the benefits of physical activity are poorly understood. Addressing thisknowledge gap may inform the appropriate integration of structured physical activityinto eating disorders treatment and recovery. We draw attention to recent findingsin the study of the impact of physical activity on the brain, and we describe the neu-rostructural and neurocognitive changes associated with physical activity observed invarious clinical and nonclinical populations. Considering the identified impairment inbrain volume- and/or neurocognitive function in various EDs, we propose that posi-tive effects of physical activity may play a meaningful role in successful ED treat-ment. Accordingly, we outline research steps for closing the knowledge gap on howphysical activity may aid in ED recovery, and emphasize the need to combine mea-sures of cognitive and behavioral responses to physical activity, with technologycapable of measuring changes in brain structure and/or function.publishedVersio

Siblings, shopping, and sustainability: Birth-order differences in green consumption

Several studies have examined the role of birth order in shaping human personality, but fewer have tested this variable in relation to other pressing issues. We conducted a birth-order study on green consumption, which enabled us to detect a small-to-moderate effect size equivalent to r = 0.15 or d = 0.30 with sufficient statistical power (N = 335). To capture green consumption, participants indicated their tendency to express the value of environmental protection through purchases and consumption behaviors. Firstborns (vs. laterborns) consistently expressed lower concerns linked to environmental protection in their purchase patterns. While the effect size of this finding was small-to-moderate by conventional standards and in direct contrast to the findings from a recent article on the same topic, these results could still be informative to address challenges associated with climate change considering the number of individuals with siblings in the world and the ease with which birth-order data can be collected.publishedVersionPaid Open Acces

Large Inter-individual Differences in Responses to a Block of High Intensity Aerobic Interval Training: a Case Series in National-level Cyclists and Triathletes

International Journal of Exercise Science 13(2): 480-487, 2020. The aim was to investigate individual responses on VO2maxand performance to a block of high intensity aerobic interval training (HIIT) in national-level endurance athletes. METHODS: National-level cyclists and triathletes (five men and two women, 31 ± 3.3 years, VO2max65.1 ± 3.3 ml·kg-1·min-1) conducted 14 HIIT sessions (4x4 min uphill running at 90-95% maximal heart rate) in nine days during preseason. VO2maxin running and cycling, lactate threshold (LT) in cycling, oxygen cost of cycling (CC), and a cycling time-trial (TT) were tested two days pre and seven days post intervention. Feasibility was determined using attendance rates, adherence (defined as completing all sessions), and reported adverse events. RESULTS: The results showed that adherence was 100% with 100% attendance rate. No adverse events were reported. TT (-75.6 ± 50.8 seconds, p\u3c 0.0001)but not VO2maxcycling (-0.2 ± 4.6 ml×kg-1×min-1, p= 0.53) or running (0.2 ± 1.2ml×kg-1×min-1, p= 0.85) was improved on group level. The individual responses varied from -8.2% to +14.5% change in VO2max, and -7.5% to +0.8% in TT. CONCLUSIONS: The large inter-individual differences in responses call for tailor-making HIIT blocks, mapping of biomarkers to avoid overtraining, and studying the effects of such blocks with longer follow-up than seven days

Hiking, indoor biking, and body liking: a cross-sectional study examining the link between physical activity arenas and adults’ body appreciation

Background Body appreciation might serve as a protective factor for developing eating disorders and is associated with participation in physical activity. Less is known about whether various arenas for physical activity may be linked to body appreciation. Therefore, the current study sought to (1) identify potential associations between physical activity level and arenas for physical activity, connectedness with nature, self-compassion, and body appreciation in adults, and (2) explore physical activity level and arenas, connectedness with nature, and self-compassion as explanatory factors for body appreciation. Methods A total of 360 adult Norwegian inhabitants (75% women, mean (SD) age 42.58 (12.30) yrs) responded to an online questionnaire. Instruments included the Body Appreciation Scale, the Connectedness with Nature Scale, and the Self-Compassion Scale. Results The percentage of participants who engaged in various physical activity arenas were 98.5% for nature, 57.5% for fitness centers, and 43.0% for organized sports. Small, positive associations were found between body appreciation and the frequency of using fitness centers and nature as physical activity arenas. Self-compassion, connectedness with nature, and frequency of using fitness centers and nature as physical activity arenas explained 39% of the variance in body appreciation. Discussion The importance of both fitness centers and nature as arenas for physical activity to explain body appreciation was surprising and might reflect different use of fitness centers among adults compared to younger age groups. Conclusion Physical activity at fitness centers and in nature were positively associated with body appreciation in adults. Self-compassion, connectedness with nature, and using fitness centers and nature as arenas for physical activity, were found to explain variation in body appreciation in adults.publishedVersio

Changes in Physical Fitness, Bone Mineral Density and Body Composition During Inpatient Treatment of Underweight and Normal Weight Females with Longstanding Eating Disorders

The purpose of this study was to examine changes in aerobic fitness, muscular strength, bone mineral density (BMD) and body composition during inpatient treatment of underweight and normal weight patients with longstanding eating disorders (ED). Twenty-nine underweight (BMI < 18.5, n = 7) and normal weight (BMI ≥ 18.5, n = 22) inpatients (mean (SD) age: 31.0 (9.0) years, ED duration: 14.9 (8.8) years, duration of treatment: 16.6 (5.5) weeks) completed this prospective naturalistic study. The treatment consisted of nutritional counseling, and 2 × 60 min weekly moderate intensive physical activity in addition to psychotherapy and milieu therapy. Underweight patients aimed to increase body weight with 0.5 kg/week until the weight gain goal was reached. Aerobic fitness, muscular strength, BMD and body composition were measured at admission and discharge. Results showed an increase in mean muscular strength, total body mass, fat mass, and body fat percentage, but not aerobic capacity, among both underweight and normal weight patients. Lumbar spine BMD increased among the underweight patients, no changes were observed in BMD among the normal weight patients. Three out of seven underweight patients were still underweight at discharge, and only three out of nine patients with excessive body fat (i.e., >33%) managed to reduce body fat to normal values during treatment. These results calls for a more individualized treatment approach to achieve a more optimal body composition among both underweight and normal to overweight patients with longstanding ED
