An average professional hockey player loses 7 pounds in one game!

Hockey players are on the ice for only one minute shifts. The workout of the game is one of the most intense in professional sports. Players say that the time on the ice is spent holding their breath. They are pushing and shoving so much that they feel they exhale almost the whole time they are on the ice. 

Players don’t have time off in the off-season like they used to, either. The sport is so demanding that they do everything possible to stay in shape. Players can lose from 5 to 8 pounds in a single game. Of course most of the loss is water weight, but it causes the players to be very conscious of the amount of their fluid intake.

Goalies don’t make it to the bench as much as other players and can lose as much weight as a forward or defenseman. They began putting water bottles on top of the goals. Sometimes, the water bottles move when goals are made, and judges and announcers have actually used this more than once to determine if a goal counted or not!
