I imagine the kinetic chain as being somewhat like cracking a whip. The energy is transferred to the arm in this case. Prior to contact, the shoulder rotation of most of the top pros slows in order to allow the arm and ultimately the racket head to accelerate.

From the ground up the kinetic chain is a result of a turning motion which then slows to transfer the energy to the next part of the chain.
