The Steak that Bobby Orr Ate would take roughly 4-6 hours to become available for the body to use as energy. The proteins would take about 10hrs before processed into a form the body can use for regeneration of muscle cells. PROTEINS are NOT stored as glycogen and DO NOT FUEL MUSCLE OR BRAIN CELLS.
There are Carb products such as GOO GEL that is available to the body within 15 minutes. One packet of goo gel would fuel an Ice hockey goalie for about 30 minutes of play time before glycogen from hte muscles and liver begin to be needed. Glover or Bee honey (2 TBLS) is an equivalent to one GOO GEL PACKET. Should you choose this route be sure to read the label and find one with NO additional additives. A good lunch product is nutriment, a liquid lunch type product. Much like ENSURE found at hte local drugstore or supermarket, its not found in all regions.
Carb loading(replenishment) is best done FOLLOWING a heavy work out. The 1-2 hours after is when the body will replenish reserves in the muscles and liver at its most rapid rate. 1 gram per kilogram in weight with in the first half hour of a work out/event and the same every 2 hours for the next 4-6 post event.
The average glycogen(stored carbs) for a male athlete is around 1500 to 2000 kilocalories. The vast majority of which is stored in the muscle cells. Some in the liver and a smaller amount in the blood.
Carb Loading can increase those stores to nearly DOUBLE in a trained athlete. Normal Carb intake would be 7-9grams of Carbs per Kilogram in weight. Carb loading would be as much as 7 days prior to an event at 9-10 grams per kilogram in weight. This also includes seriously reduced activity up to 3 days prior and VERY limited activity the day of. Unless your a PRO, its both a difficult task and unnecessary(IMHO)
Carb Boosting would be near the same for post event replenishment. This is where you will get a HUGE BOOST. Complex carbs would be 4-6 hours prior and simple no less than 2 hours prior wiht out first adapting hte body to a shorter time frame(Use practices to adapt tyour body to changes) Carb drinks may be consumed closer to the event start. IF you wish to intake just PRIOR to start be sure to begin prepping the stomach at practices. Allow the body time to adjust before attempting just prior to a game.
Bottom line....complex carbs 4 hours prior at the least. Pasta, breads, whole grains, for instance. Simple Carbs can be as much as right up to and DURING game play. FRESH FRUIT would be one example.
