Getting Ready Before the Game: Hydration and Energy for Young Athletes

Talent and practice matter, but two of the biggest factors in how a young athlete performs on game day rarely show up on a stat sheet: how hydrated they are, and what kind of fuel is actually in their system beforehand.

Hydration: start before they're thirsty

Pediatric sports medicine specialists are consistent on this point: don't wait for a child to say they're thirsty before encouraging fluids. By the time thirst kicks in, a young athlete is often already behind on hydration, and kids regulate body temperature less efficiently than adults, which raises the stakes in hot or humid conditions.

The general guidance from pediatric hydration research is straightforward: water is the right default before and during most youth sports activity. Only after roughly 60-90 minutes of sweating does a low-sugar electrolyte drink become useful, to help replace sodium lost through sweat. Caffeinated energy drinks are a different story entirely — pediatric sports medicine physicians are explicit that these are not appropriate for young athletes, since the concentration of caffeine can pose real safety risks to a developing body.

Why carbohydrates — and why simple ones — before activity

Carbohydrates are the primary fuel source for both muscles and the brain during physical activity, and youth sports nutrition research is increasingly clear that restricting carbs in young athletes carries real risk — including impaired growth, slower recovery, and reduced focus during competition.

Timing matters too. Simple carbohydrates — the fast-digesting kind — are specifically useful in the window right before activity, because they convert to usable energy quickly without sitting heavy in the stomach. Fiber-rich, complex carbohydrates are valuable earlier in the day, but immediately before a game or practice, easily digestible energy is what a young athlete's body can actually use in time.

What this looks like in practice

A simple, practical approach: water throughout the day, a light carbohydrate-containing snack in the hour before activity, and electrolyte replacement only once real sweating has been sustained for over an hour. Kiddos+ IGNITE PRE was built around two of these exact needs — B-vitamins to support carbohydrate metabolism and steady energy, and sodium and potassium citrate to support electrolyte balance — in a stimulant-free gummy formulated for ages 10-17, with zero caffeine.
