  We present a kinematic study of a large sample of chromospherically active
binaries (CAB) in order to determine their membership to representative young
disk stellar kinematic groups: the Local Association (Pleiades moving group, 20
- 150 Myr), Ursa Mayor group (Sirius supercluster, 300 Myr),
  Hyades supercluster (800 Myr), IC 2391 supercluster (35 Myr) and Castor
moving group (200 Myr). Precise measurements of proper motions and parallaxes
taken from Hipparcos Catalogue and published radial velocity measurements are
used to calculate Galactic space motions (U, V, W) in order to determine the
membership of the selected stars to the different stellar kinematic groups.
