In this review, the authors included 29 trials (n=1,109 participants) which investigated the effect of any type of exercise (aerobic, strength, yoga) for clinical symptoms (total, positive, and negative), quality of life, global functioning, depression and cognition for people with schizophrenia. Exercise interventions reduced total symptom severity (Hedges’ g=0.37), positive symptoms (Hedges’ g=0.32) and negative symptoms (Hedges’ g=0.49) compared to control conditions. Effects were larger for exercise compared to passive controls than for exercise compared to active controls. For the secondary outcomes, exercise was superior to control conditions in improving quality of life, global functioning, and reducing depression with medium to large effect sizes. Only yoga improved cognition.
