The efficacy of aerobic exercise and resistance training for anxiety-related disorders and constructs: A randomized controlled trial
Bibliographic record
Abstract
Anxiety-related disorders are highly prevalent and comorbid, affecting nearly one third of individuals over their lifetime. Evidence suggests that anxiety-related disorders share common etiology, latent structure, higher-order dimensions, and response to treatment. These similarities have fostered the development of transdiagnostic treatments that can effectively target a relatively wide array of anxiety-related psychopathological concerns and can also be widely and efficiently disseminated to individuals in need treatment. There is empirical evidence to support the use of physical activity, primarily aerobic exercise, as an effective intervention to treat a variety of mental health concerns; however, what effect exercise has on anxiety-related disorders and constructs (e.g., anxiety sensitivity) using an integrative, transdiagnostic approach is unknown. Therefore, the purposes of the current trial were: (1) to quantify the effects of aerobic exercise and resistance training on symptoms of anxiety-related disorders and constructs, (2) to evaluate whether both modalities of exercise were equally efficacious in reducing such symptoms, and (3) to determine whether exercise enjoyment and pre-intervention physical fitness were associated with symptom reduction. A total of 48 individuals with anxiety-related disorders were randomized to one of three conditions: aerobic exercise, resistance training, or a waitlist control. Symptoms of anxiety-related disorders, related constructs (i.e., general psychological distress, depression, anxiety, stress, anxiety sensitivity, distress tolerance, intolerance of uncertainty), and exercise enjoyment were assessed at pre-intervention and weekly during the 4-week intervention. Participants were further assessed 1-week and 1-month post-exercise. Both aerobic exercise and resistance training were efficacious in improving disorder status. Additionally, aerobic ii exercise was efficacious in improving general psychological distress and anxiety, while resistance training was efficacious in improving disorder-specific symptoms, anxiety sensitivity, distress tolerance, and intolerance of uncertainty. For both types of exercise, lower pre-intervention physical fitness was associated with greater reductions in general psychological distress. For aerobic exercise, lower physical fitness was also associated with greater reductions in stress. Scores at follow-up were generally not significantly different when compared to post-intervention. Results highlight the efficacy of aerobic exercise and resistance training in uniquely addressing anxiety-related disorder symptoms and constructs.

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.
