Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age.

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups.

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.

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.

The Healthy Body Image Intervention and Reduction in Eating Disorder Symptomatology and Muscle Building Supplement Use in High School Students: A Study of Mediating Factors.

Background: Mediation analysis is important to test the theoretical framework underpinning an intervention. We therefore aimed to investigate if the healthy body image (HBI) intervention's effect on eating disorder (ED) symptomatology and use of muscle building supplements was mediated by the change in risk and protective factors for ED development and muscle building supplement use.

Methods: This study used data from the HBI intervention: a cluster randomized controlled universal intervention aiming to promote positive body image and embodiment and reduce the risk for ED development including 30 schools in Norway.

Effect of aerobic exercise intensity on health-related quality of life in severe obesity: a randomized controlled trial.

Background: Aerobic exercise is an important part of obesity treatment and may improve health-related quality of life (HRQOL). The objective of this study was to compare the effect of two different exercise programs on health-related quality of life in patients with severe obesity.

Methods: This was a single-center, open-label, randomized, parallel-group study comparing the effects of a 24-week moderate-intensity continuous training (MICT) program and a combined high-intensity interval training program with MICT (HIIT/MICT).

Exercise Dependence and Body Image Concerns Amongst Group Fitness Instructors: A Self-Determination Theory Approach.

Introduction: Despite the fact that group fitness instructors serve as significant role models with potentially great impact on class participants' motivation for exercise, they are a very under-researched group. The aim of this study was therefore to examine group fitness instructors' motivational regulations for exercise, and how these motivational regulations can predict symptoms of exercise dependence and body image concerns.

Methods: Group fitness instructors from the largest fitness companies in Norway ( = 837, response rate: 57%) completed an online survey with reference to the Situational Motivation Scale (SIMS), the Exercise Dependence Scale (EDS), the Eating Disorders Inventory subscales drive for thinness (EDI-DT) and body dissatisfaction (EDI-BD), and their weekly amount of exercise and instruction.

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

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.

Protein, Creatine, and Dieting Supplements Among Adolescents: Use and Associations With Eating Disorder Risk Factors, Exercise-, and Sports Participation, and Immigrant Status.

This study aimed to estimate the number of weekly users of protein, creatine, and dieting supplements and to explore whether weekly use was related to eating disorder (ED) risk factors, exercise, sports participation, and immigrant status. In total, 629 and 1,060 high school boys and girls, respectively, self-reported weekly frequency of protein, creatine, and dieting supplement use, and weight and shape concerns, appearance internalization and pressure, self-esteem, mental distress, physical activity level, exercise context, and the type and weekly frequency of sport played. Multiple hierarchical regression analyses were performed to investigate explanatory factors for supplement use.

Compulsive exercise and mental health challenges in fitness instructors; presence and interactions.

Background: Some physically active people exercise compulsively, which can be associated with several mental health challenges. Fitness instructors are considered important role models for an active, healthy lifestyle; yet little is known about their exercise motives and mental health. The aim of this study was to examine the presence of compulsive exercise and mental health challenges, and their interaction, in fitness instructors.

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 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.

Body appreciation and body appearance pressure in Norwegian university students comparing exercise science students and other students.

Background: Body image is considered a core issue for public health and associates with university students' overall health. Due to positive associations between exercise and body image, it has been suggested that students within an exercise science program might be more body appreciative compared to other students. On the other hand, the strong societal idealization of the athletic body may expose them to a pressure of having a specific body appearance, which may result in unfavorable health consequences.

Responses to Maximal Strength Training in Different Age and Gender Groups.

Purpose: The present study aimed to investigate the potential impact of age, gender, baseline strength, and selected candidate polymorphisms on maximal strength training (MST) adaptations.

Methods: A total of 49 subjects (22 men and 27 women) aged 20-76 years, divided into five age groups, completed an 8 weeks MST intervention. Each MST session consisted of 4 sets with 4 repetitions at ∼85-90% of one-repetition maximum (1RM) intensity in leg-press, three times per week.

Body Figure Idealization and Body Appearance Pressure in Fitness Instructors.

Purpose: The fitness centers are settings for health promotion, yet may serve as a stage for counterproductive figure idealization. Such idealization may take the form of a drive toward the thin, the muscular, or lean body figure ideal, which all hold the potential to impel an experience of body appearance pressure (BAP) and body dissatisfaction. The aim of this study was to explore figure idealization, body dissatisfaction, and experience of BAP in fitness instructors.
