Dr. Vyas: Water is probably the most important; however, loss of minerals is a well-known issue with dehydration and fatigue. I’d do a 3:1 combination of water to sports drink during the game. Before the game, the recommendation is 5ml per kg body weight of water, up to four hours prior to exercise. Electrolyte replacement with snacks and beverages that contain sodium after the game will help retain fluid in preparation for the next day’s practice. An important concept that is sometimes forgotten is to start the hydration process well before the practice or game (several hours prior to participation). It is difficult to catch up with water balance once the fluid loss process is underway during the activity. For more information on common hockey injuries, visit our hockey training section.
