What Your Kid Eats and How They Sleep Matters More Than the Warm-Up

What your child eats in the 24 hours before a game — and how well they sleep the night before — has more impact on their performance than almost anything that happens at training.

That’s not opinion. It’s what the research into youth sports performance consistently shows. And yet for most junior athletes, game day prep means a rushed breakfast, a water bottle grabbed on the way out the door, and a late night on Friday because no one remembered the game was at 8:30am.

This guide is for parents who want to actually do something about it.


Why Game Day Starts the Day Before

Most parents think about pre-game nutrition as the meal before kick-off. In reality, your child’s energy stores, hydration levels, and mental sharpness on game day are largely set by what happened in the 12–24 hours prior.

Glycogen — the fuel muscles run on — takes time to build. A carbohydrate-rich dinner the night before a Saturday morning game does more for on-field energy than anything eaten on the morning itself. Pasta, rice, bread, potato. Nothing exotic. Just consistent, and timed right.

Hydration works the same way. Kids who arrive at the ground already dehydrated can’t catch up by drinking at half-time. By the time they feel thirsty, they’re already behind.

Sleep is where most families lose the most ground without realising it. A child who gets seven hours instead of nine doesn’t just feel tired — their reaction time slows, their decision-making suffers, and their body’s ability to regulate effort drops noticeably. For junior athletes aged 8–15, nine hours is the floor, not the ceiling.


What the Timeline Actually Looks Like

Here’s a simple game day prep framework that works for most junior athletes, regardless of sport.

The night before

Dinner should be carbohydrate-forward — pasta, rice, noodles — with a moderate serve of protein and not too much fat or fibre, which slows digestion. Avoid anything new or experimental. Game night is not the time to try a new restaurant.

Devices off and lights dim at least an hour before bed. Screens suppress melatonin and delay the onset of deep sleep. If your child is wound up after training or a school week, a consistent wind-down routine — shower, light reading, quiet time — makes a real difference.

Aim for lights out with enough time to get nine hours before the alarm.

Morning of the game

Breakfast 2–3 hours before kick-off if possible. Oats, toast, banana, eggs — easy-to-digest carbohydrates with a small amount of protein. Avoid heavy, fatty, or high-fibre meals that sit in the stomach.

Start drinking water with breakfast. Not a big glass right before warm-up — steady intake from when they wake up.

In the 60 minutes before

A small top-up snack is fine if it’s been more than two hours since breakfast — a banana, a slice of toast, a handful of crackers. Nothing heavy.

Keep sipping water. For games longer than an hour in warm conditions, a sports drink during the game (not before) can help replace electrolytes.

At half-time

Water first, always. If it’s a long game or a hot day, a small carbohydrate snack — orange slices, a muesli bar — helps maintain energy for the second half.


The Part That’s Hard: Actually Remembering All of This

Knowing the framework is one thing. Acting on it consistently — across a full season, with school nights, busy weekdays, and Saturday morning chaos — is something else entirely.

This is exactly why ScorX built game day preparation reminders into the app.

When you schedule an upcoming game in ScorX, the app automatically sends you timely notifications in the lead-up — reminding you when to think about dinner the night before, when to get your child winding down for sleep, when to sort breakfast, and when to start hydrating. Not a wall of information to read and remember. Just a quiet nudge at the right moment.

It’s the difference between knowing good preparation matters and actually doing it, week after week, without it falling through the cracks.


Does It Actually Make a Difference at Junior Level?

Parents sometimes wonder whether this level of preparation really matters at junior sport — especially for recreational players who are just there to have fun.

It matters. Not because the goal is elite performance, but because a well-rested, well-fuelled child enjoys the game more. They stay engaged longer, they make better decisions with the ball, and they recover faster. They’re also less likely to come home grumpy and exhausted and declare they want to quit.

Good preparation doesn’t make the game more serious. It makes it more enjoyable.

And if you’re already tracking your child’s stats in ScorX, you might notice it yourself — compare their numbers on games where preparation went well against the games where it didn’t. The pattern tends to show up.


Frequently Asked Questions

How much water should a junior athlete drink before a game?

A general guide is around 400–600ml of water in the two hours before a game, sipped gradually rather than all at once. During the game, offer water at every break. In hot weather, increase this and consider a sports drink during longer games.

What’s the best meal the night before a game?

Pasta, rice, or noodles with a simple protein like chicken or fish and some vegetables. Keep fat and fibre moderate — both slow digestion. The goal is a comfortable, well-fuelled start to sleep, not a heavy meal.

How many hours of sleep does a junior athlete need before game day?

For children aged 8–12, aim for 10 hours. Teenagers aged 13–17 need at least nine. These aren’t ideal targets — they’re the minimums for normal cognitive and physical function. Game day is not the day to catch up on a sleep debt.

My child says they’re not hungry before a game. Should I force them to eat?

Don’t force it, but don’t skip it entirely either. Pre-game nerves are real and can suppress appetite. A small, easy-to-digest snack — half a banana, a few crackers — is better than nothing. Make sure they’ve eaten well the night before so the morning meal is a top-up, not the main event.

How does ScorX send game day preparation reminders?

When you add an upcoming game to ScorX, the app automatically schedules a series of reminders based on the game time — covering sleep, nutrition, and hydration at the right moments in the lead-up. No setup required. Just enter the game and let ScorX handle the timing.


ScorX is free to download. Add your next game, and let the app take care of the reminders.
