Basically, alcohol after a game is not recommended. First, consuming alcohol immediately after activity means you are likely displacing calories and nutrients from other hydrating beverages and food. Water or sports drinks should be consumed until you are fully refueled and rehydrated.
The reason for this is that alcohol delays muscle glycogen recovery and it is a vasodilator. A vasodilator actually can speed up blood flow to injured areas causing further damage or bruising, making the injury worse and the recovery take even longer. If you are going to indulge, follow your recovery schedule and save the alcohol until your post-game meal. Drink 3 cups sports drink for every pound sweat lost within the first 15-20 min. post-game to replace fluids and energy. Usually it is recommended that you then follow that up with a balanced meal within 2 hours. This would be a better time to enjoy a beverage if you choose.
