It's mostly a skill you build playing the game.

A shift is often a full sprint while on ice. A player's body communicates to him or her pretty clearly, it's time to get off. Sometimes things get in the way. Defense coverage, an icing call that disallows a switch, some other things. But for the most part it's just a skill one builds. You skate your shift, you get off, you rest three shifts, you skate your shift, you get off.
