What is that?
I would like to second @seagoal and say that hydration is important. Make sure you have enough water before games, drink in small amounts during games (at stoppages with the faceoff in the other zone, after goals, or between periods), and make sure to drink after each game ends.
If you have time to shower between games, do that. I've noticed that warm showers help relieve muscle tightness and small aches. You'll also feel mentally refreshed, especially when you put on clean clothes afterwards. I NEED to shower after games because I have sensitive skin and sweat like crazy, but I would say a good shower also helps.
