It's likely there was no "sparring" in the sense of taking turns attacking and defending, give and take in a competitive match (or practicing for one). It was all "taking." The aim was to dispatch the opponent ASAP, the strategy being to attack without the possibility of countering until he was crushed. In close quarters actual combat there is little time to engage in fancy tactics. It's very direct and offensive. This was the doctrine Motobu Choki followed.
Most training, it is thought, was in the form of intensive two-man drills, much like modern special forces combat training. They do not learn to "spar." They practice to incapacitate and kill without sending their training partner to the hospital. During the 1800's many of the practitioners were government security personnel trained to be prepared for serious combat and had experience in such encounters.
That has pretty much changed in the military.
