Prestroke physical activity is associated with admission haematoma volume and the clinical outcome of intracerebral haemorrhage.

Light PA ≥4 hour/week prior to ICH was associated with smaller haematoma volumes in deep and lobar locations. Physically active patients with ICH had a higher likelihood of mild stroke, a good 1-week functional status and 90-day survival, in part mediated by smaller haematoma volumes on admission.
