Included studies met the following criteria (1): participants aged \u226518 years with BD diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) or International Classification of Diseases, 11th Revision (ICD-11) criteria (2); exercise as the primary intervention (3); control groups receiving standard rehabilitation treatment. Study quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. Meta-analyses were performed using Stata 18.0, and evidence quality was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 7 RCTs n=576 were included. Meta-analysis demonstrated that exercise significantly improved depressive symptoms (SMD =-0.63, 95%CI: -1.11 to -0.14, P=0.01) and anxiety symptoms (SMD =-0.70, 95%CI: -1.26 to -0.15, P&amp;lt;0.05) in BD patients, but showed no significant effect on manic symptoms (SMD =-0.23, 95%CI: -0.67 to 0.21, P&amp;gt;0.05). Subgroup analyses revealed that exercise protocols featuring session duration \u22641 hour\/session (SMD= -0.86, P=0.02), frequency &amp;gt;5 sessions\/week (SMD = -0.76, P&amp;lt;0.01), and intervention period \u226412 weeks (SMD = -0.79, P=0.02) produced more pronounced improvements in depressive symptoms. The GRADE approach rated the quality of evidence as low for all outcomes (depression, anxiety, mania), with downgrading factors including substantial heterogeneity, imprecision, and risk of bias.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Current low-quality evidence suggests that exercise may alleviate depressive and anxiety symptoms in BD patients (particularly with high-frequency, prolonged-duration, short-term protocols), while its effect on manic symptoms remains inconclusive. These findings should be interpreted cautiously due to methodological limitations of included studies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Systematic review
