Cerebral perfusion
Tijdsspanne: baseline and 4-weeks
|
Magnetic resonance imaging (MRI)-based cerebral perfusion are assessed before and after the 4-weeks of physical fitness training. Primary and secondary endpoints are specified after completion of the interim analysis after inclusion of the first 24 patients (first stage). In a second stage the study is conducted with specified primary and secondary endpoints with recruitment of up to 76 remaining patients. |

Blood-derived biomarkers
Tijdsspanne: baseline and 4-weeks
|
Changes in blood biomarkers are assessed before and after the 4-weeks intervention of physical fitness training. Primary and secondary endpoints are specified after completion of the interim analysis after inclusion of the first 24 patients (first stage). In a second stage the study is conducted with specified primary and secondary endpoints with recruitment of up to 76 remaining patients. |

functional outcome
Tijdsspanne: 3 months
|
Analyzing how changes in imaging measures and blood-derived biomarkers are related to each other and to differences in functional outcome, in particular gait speed, Barthel index (co-primary endpoints of PHYS-STROKE) and modified Rankin Scale
|
3 months

|
endothelial function assessment
Tijdsspanne: measurement before and after the 4 weeks intervention
|
the endothelial function of included patients will be assessed prospectively before and after the 4 week intervention with the Endopat2000 device.
First measurement was conducted in January 11th 2014.
Results will be correlated with imaging and blood-derived biomarkers as well as differences between intervention groups.

Clinical biomarkers including vital Parameters
Tijdsspanne: measurements at baseline and all follow-up time points (measurement before and after the 4 weeks intervention, at 3 months and at 6 months after stroke)
|
systolic and diastolic blood pressure, resting heart rate, body-mass-index, and waist-to-hip-ratio over time compared between study groups
|
measurements at baseline and all follow-up time points (measurement before and after the 4 weeks intervention, at 3 months and at 6 months after stroke)
