Progressive resistance exercise as complementary therapy improves quality of life and body composition in anorexia nervosa: A randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: and purpose: Exercise has not typically been used as an adjunct in treatment of anorexia nervosa (AN). This study aimed to examine the effects of progressive resistance exercise (PREx) on perceived quality of life (QoL) and body composition in adolescents with AN. MATERIALS AND METHODS: Forty-four adolescents diagnosed with AN were randomly allocated to either PREx or control groups after hospitalization. The PREx group completed twenty-four PREx sessions over two months including three sets of 8-10 repetitions of eight whole-body exercises at a moderate intensity. QoL and body composition were evaluated at baseline and after two months using Health Questionnaire Short-Form 36 (SF-36) and anthropometric measurements. RESULTS: were analyzed. Significant group x time effects were found on SF-36 role physical (RP) scores. Significant improvements with large effect sizes (d > 0.72) were found in RP, and arm circumferences in the PREx group. Spearman association analyses between percent change in anthropometric variables and change in QoL scores showed positive associations with moderate-to-large effect sizes in the PREx group among the following variables: mid-thigh-circumference, physical functioning (PF) and general health (GH); calf-circumference relaxed and body pain; biceps skinfold and GH scores; triceps-skinfold, and role physical (RP) and vitality (VT); supraspinale-skinfold and RP and VT; mid-thigh-skinfold and calf-skinfold and VT. CONCLUSION: PREx after hospitalization enables modest positive changes in QoL associated to anthropometric changes in adolescents with AN without adverse effects on weight recovery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
