Hydration and Nutrition Tips for Young Tennis Athletes

Young athletes dehydrate faster than adults relative to body size, and the effects show up quickly on court — slower reaction time, reduced concentration, and earlier fatigue. Regular water breaks during training aren't optional extras; they're performance essentials.

Pre-training meals should combine easily digestible carbohydrates with a modest amount of protein, eaten roughly 1-2 hours before a session — enough time to digest without leaving a player training on an empty stomach.

Post-training recovery matters too, and it's often skipped by young athletes rushing off to the next activity. A simple combination of water, a light snack, and some protein within an hour of finishing helps recovery for the next session.

Sugary sports drinks are rarely necessary for training sessions under 90 minutes — plain water is usually sufficient, with electrolyte drinks reserved for longer sessions or particularly hot, humid days when sweat loss is significant.

We also encourage parents to normalize water breaks rather than treating them as a sign of low effort. Hydrating proactively, before thirst even sets in, keeps performance consistent through a full session instead of tapering off in the final twenty minutes.

Individual sweat rates vary considerably between players, which is why we discourage one-size-fits-all hydration rules in favor of teaching players to recognize their own signals — the color of urine, how heavy or light they feel mid-session, whether cramping has ever been an issue for them specifically. Some young athletes genuinely need more frequent fluid intake than their teammates training on the exact same court under the exact same conditions, and treating hydration as a personalized habit rather than a fixed schedule produces better long-term results than a generic rule applied uniformly to an entire training group regardless of individual differences. We build this self-awareness gradually, the same way we build any other trainable skill.
