Actually a faster way is to get these direct in the geometry tree:
geometry = ExtAPI.DataModel.Project.Model.Geometry
bodies = geometry.GetChildren(DataModelObjectCategory.Body, True)
for body in bodies:
name = body.Name
print(str(name)+"; ")
print(str(body.Minimum)+"; ")
print(str(body.Maximum)+"; ")
print(str(body.Average)+"; ")
