Why this matters more than it seems

Most grassroots coaches spend hours planning drills and very little time thinking about fuel — but an under-fed or dehydrated player will look "off" in ways that are easy to misdiagnose as a technical or fitness problem. Sluggish decision-making, heavy legs late in a session, and a sudden drop-off in concentration are all classic signs of a player running on empty, not a player who needs more repetitions. You can't control what happens at home, but a few simple, consistent habits around training and match days make a genuine difference to how players perform and recover.

Before training/match (2–3 hours prior)

Ideal meal: Carbs + protein, moderate fat, easy to digest.

Examples: • Toast with peanut butter + banana
• Chicken + rice + vegetables
• Pasta with tomato sauce
• Oats with honey and berries

Avoid: Heavy fat, high fibre right before (causes stomach discomfort). Nothing within 30 minutes of kick-off.

Hydration: 500ml water 2–3 hours before. Sip small amounts (don't overload the stomach).

During training (if over 60 minutes)

For sessions under 60 min: water only.

For sessions 60–90 min: water + carb drink (sports drink, juice diluted 50/50 with water, or a banana at half-time).

For matches 70+ min: 200ml carb drink every 20 minutes (small sips, not gulps).

After training/match

Within 30 minutes (recovery window): Carbs + protein.

Examples:

  • Chocolate milk (surprisingly effective)
  • Yoghurt + granola
  • Sandwich + fruit
  • Smoothie with protein powder

This refuels glycogen stores and starts muscle repair.

Age considerations

U7–U10: Appetite-driven (let them eat when hungry). Focus on water during activity. Don't over-complicate.

U11–U13: Can follow a basic pre/post routine. Energy demand increasing. Make sure they're eating enough overall.

U14+: Can follow adult nutrition guidelines. Energy demand is high (many players are growing + training hard).

Spotting under-hydration on the pitch

You don't need to test anything to catch this early — the practical signs are visible from the sideline. A player who's stopped sweating on a warm day despite working hard, who seems unusually tired or irritable in the second half of a session, or who complains of a headache or feeling "not right" is worth a water break and a quick check-in, not a push to carry on. The simplest heuristic to pass on to parents: if a child hasn't needed the toilet in the hours before training, they've probably not drunk enough.

Hot weather sessions

On genuinely hot days, build water breaks into the session rather than waiting for players to ask — most children under-report thirst, especially mid-game. A short 60–90 second break every 15–20 minutes costs you very little session time and meaningfully reduces the risk of a player overheating. Light-coloured kit, shade for the water table if you have it, and moving the most intense parts of a session to earlier or later in a hot session are all sensible, low-effort adjustments.

Common mistakes

The most frequent one is a heavy meal too close to kick-off — a big meal within an hour of training sits undigested and genuinely affects a player's ability to move freely, regardless of how good the food itself is. The second is relying entirely on sports drinks: for the vast majority of grassroots sessions (under an hour, moderate intensity), water is genuinely all that's needed, and a sugary drink adds calories without a real performance benefit. The third is assuming a player who says they're "fine" has eaten that day — some children, particularly younger ones, simply don't register hunger reliably during an exciting session.

Dietary needs and allergies

If you provide any snacks or drinks as a club or team — post-match orange segments, a half-time snack rota — always check with parents first about allergies (nuts are the most common serious one) and any dietary restrictions. The safest approach for team-provided food is to ask parents to flag any requirements at the start of the season and keep a simple note of who needs what, rather than relying on memory on the day.

What you can't control

Home nutrition is the parent's job. You can educate (send a brief nutrition guide), but you can't force it. Focus on hydration during training (which you do control) and post-training snack (if possible).

Tournament and multi-match day fueling

A day with several matches back-to-back needs a slightly different approach from a single training session — small, easily digestible snacks between matches (a banana, a small sandwich, dried fruit) rather than one large meal keep energy topped up without the sluggishness of a big meal sitting undigested before the next kickoff. Encourage sipping water steadily through the gaps between matches rather than waiting until a player says they're thirsty, since thirst tends to lag well behind actual need once a player's been active for several hours.

When a family's circumstances make this harder

Not every family can easily provide the ideal pre-match meal or snack, whether due to cost, time, or other pressures, and it's worth being sensitive to this rather than assuming every gap in nutrition reflects a lack of care. If you notice a player consistently arriving without having eaten, a quiet, non-judgemental word with the parent — framed around performance and energy rather than criticism — is more useful than a generic nutrition handout, and some clubs are able to help directly with things like shared post-match snacks if cost is a genuine barrier.
