There is no secret diet or techniques to prepare you for a match. Keep it simple and listen to your body
Many players and coaches advocate a large carb load the night before or even two days before a match. Carb loading can cause players to feel lethargic and tired. Carb loading should be avoided but that doesn’t mean carbs should be avoided. Eat moderate amounts of low GI carbs the day before just to make sure muscle glycogen is filled and your body is 100% ready to go on match day. Hydration is critical so you want to make sure you consume at least 3-4 litres of water the day before.
