Abstract

BACKGROUND: Physical exercise may be valuable for patients with schizophrenia spectrum disorders as it may have beneficial effect on clinical symptoms, quality of life and cognition. METHODS: A systematic search was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Controlled and uncontrolled studies investigating the effect of any type of physical exercise interventions in schizophrenia spectrum disorders were included. Outcome measures were clinical symptoms, quality of life, global functioning, depression or cognition. Meta-analyses were performed using Comprehensive Meta-Analysis software. A random effects model was used to compute overall weighted effect sizes in Hedges' g. RESULTS: Twenty-nine studies were included, examining 1109 patients. Exercise was superior to control conditions in improving total symptom severity (k = 14, n = 719: Hedges' g = .39, P < .001), positive (k = 15, n = 715: Hedges' g = .32, P < .01), negative (k = 18, n = 854: Hedges' g = .49, P < .001), and general (k = 10, n = 475: Hedges' g = .27, P < .05) symptoms, quality of life (k = 11, n = 770: Hedges' g = .55, P < .001), global functioning (k = 5, n = 342: Hedges' g = .32, P < .01), and depressive symptoms (k = 7, n = 337: Hedges' g = .71, P < .001). Yoga, specifically, improved the cognitive subdomain long-term memory (k = 2, n = 184: Hedges' g = .32, P < .05), while exercise in general or in any other form had no effect on cognition. CONCLUSION: Physical exercise is a robust add-on treatment for improving clinical symptoms, quality of life, global functioning, and depressive symptoms in patients with schizophrenia. The effect on cognition is not demonstrated, but may be present for yoga.

  • In schizophrenia spectrum disorders, aerobic exercise does not improve depressive symptoms.

    “Data from one MA [69] of 5 RCTs found that aerobic exercise does not improve depressive symptoms”

    From Exercise as Medicine for Mental and Substance Use Disorders: A Meta-review of the Benefits for Neuropsychiatric and Cognitive Outcomes (2020) · cites this paper as [69]

    The Discussion (page unavailable) says the evidence for reducing depressive symptoms points more toward yoga than aerobic exercise, but it does not state that aerobic exercise has no effect on depression. The Secondary Outcome Measures report a significant reduction in depression for exercise overall, and Table 1 lists seven studies for that outcome, not five RCTs. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • In people with anxiety and stress disorders, exercise was effective versus non-active interventions in reducing anxiety symptoms.

    “In those with anxiety and stress disorders, there was evidence that exercise was effective versus non-active interventions in reducing anxiety symptoms [33,34,69].”

    From Exercise as Medicine for Mental and Substance Use Disorders: A Meta-review of the Benefits for Neuropsychiatric and Cognitive Outcomes (2020) · cites this paper as [69]

    The Type of Exercise section says physical exercise reduces state anxiety and psychological distress in people with schizophrenia. The paper does not establish the claimed effect in people with anxiety or stress disorders, or specify a comparison with non-active interventions for the anxiety outcome. The passive-control comparisons in Primary Outcome Measure: Clinical Symptoms concern schizophrenia symptom severity, not anxiety symptoms. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Aerobic exercise does improve depressive symptoms in schizophrenia.

    “It does appear from the paucity of RCTs available that aerobic exercise does improve depressive symptoms in schizophrenia [69].”

    From Exercise as Medicine for Mental and Substance Use Disorders: A Meta-review of the Benefits for Neuropsychiatric and Cognitive Outcomes (2020) · cites this paper as [69]

    The Secondary Outcome Measures section reports that exercise overall reduced depression in patients with schizophrenia spectrum disorders. The Discussion says the evidence for reducing depressive symptoms points more toward yoga; it does not establish the claimed improvement specifically for aerobic exercise. No page number is available in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In schizophrenia spectrum disorders, exercise as an adjunctive treatment reduces negative symptoms compared with control.

    “as an adjunctive treatment for reducing positive and negative symptoms of schizophrenia (metaanalyses = 2)”
  • In schizophrenia spectrum disorders, exercise as an adjunctive treatment reduces positive symptoms compared with control.

    “as an adjunctive treatment for reducing positive and negative symptoms of schizophrenia (metaanalyses = 2)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
