How do hockey players know when to substitute and when they are being substituted for? My theory was that they were all connected by a hive mind.
you skate as hard as you can. for the pros, that means their shift is 40-60 seconds, then you get tired at the same time your line mates do, so you change.
for the younger players, usually you’re told to follow your center off, once you see different line mates you know its time to head off
The coach usually yells change it up or something to the nature.

Coaches might "call them off" but if you’ve played long enough, you’d know that as
a forward your shift is about 30 – 45 seconds, and 60 – 90 seconds if a defenceman

Coach sometimes will tell players when to change it up, but most of the time just tells which line is going next to the players. Most of the players know shifts are only 40-60 seconds and will come off if they are tired, so usually the coach doesn’t have to call them off. Also players from the bench will also sometimes call for a change when they feel one should be made.

There coach calls them for a change but they are usually 30-50 second shifts anyway so they know when they have to get off.

When an athlete begins to enter anaerobic exercise range his muscles begin to pain slightly.
A hockey player’s efficiency decreases very rapidly once his energy enters this phase. Through experience he knows that if he doesn’t get off the ice before this starts he won’t be ready as soon as he is needed again.
Rebound from aerobic energy is quick from anaerobic much slower. So for efficiency and strength players should never enter into the anaerobic phase during a game.
