Fueling Juniors Before Training: 5 Essential Pre-Session Tips
Parents often underestimate how much fueling juniors before training affects mood, confidence, and overall performance.
For young tennis players, what they eat before training has a major impact on energy, focus, endurance, and overall enjoyment of the session. Fueling juniors before training is more than giving them a quick snack - it’s a strategic approach that helps their developing bodies perform at their best without early fatigue or mood crashes.
Unlike adults, children burn energy quickly and rely heavily on consistent carbohydrate availability. When the body runs low, focus drops, frustration rises, and technique breaks down. Good pre-training nutrition keeps sessions productive and helps build long-term healthy habits.
Here are five essential guidelines for fueling juniors before training, ensuring they step on court ready to perform.
1. Choose Slow-Release Carbohydrates 1-2 Hours Before Training
The best foundation for pre-training nutrition is steady, long-lasting energy. Slow-release (low-GI) carbohydrates provide a consistent fuel source throughout the session and prevent sudden highs and lows.
Great slow-release options include:
-
Whole-grain toast with nut butter
-
Oatmeal topped with banana or berries
-
Whole-grain pasta leftovers
-
Brown rice with a light protein
-
Greek yogurt with fruit
-
A small baked sweet potato
These foods maintain stable blood sugar and support sustained concentration.
Avoid sugary cereals, pastries, or sweetened drinks before training - they cause quick energy spikes followed by an early-session crash.
2. Prioritize Hydration Throughout the Day, Not Just Before Training
Many children arrive at training already slightly dehydrated, especially after school. Hydration should be a day-long habit, not a last-minute task.
Encourage juniors to sip water:
-
in the morning
-
during school
-
at lunch
-
on the way to training
Signs of dehydration include headaches, low energy, irritability, and difficulty focusing - problems that hinder both learning and performance.
For most sessions, water is enough. On hot days or longer practices, a diluted electrolyte drink can help maintain balance.
3. Include Light Protein for Stable Energy and Muscle Support
Carbohydrates power the session, but light, digestible protein helps maintain stable energy and supports muscle recovery.
Good pre-training protein sources include:
Keep portions moderate - too much protein too close to training can cause discomfort or sluggishness.
4. Avoid Heavy, Fatty, or High-Fiber Meals Before Training
Even nutritious foods can cause issues if eaten too close to activity. Large or heavy meals divert blood flow to digestion rather than movement, leading to:
-
stomach cramps
-
bloating
-
sluggish footwork
-
early fatigue
Foods to avoid within two hours of training:
-
burgers or fried food
-
creamy sauces
-
high-fiber salads
-
large sandwiches
-
fast food
The goal is simple: light, steady energy - not a full stomach.
5. Use a Quick Energy Booster 10-20 Minutes Before Training
Many juniors begin training after a long school day, which means their energy reserves are naturally low. A quick-release carbohydrate shortly before practice provides an immediate lift.
Great quick boosters include:
Avoid chocolate or sugary drinks - these cause an energy spike followed by a crash.
This last-minute fueling strategy is widely used in high-performance junior programs worldwide.
Putting It All Together: A Simple Pre-Training Routine
A practical, easy-to-follow plan looks like this:
1-2 hours before practice:
Whole-grain toast + Greek yogurt (or any slow-release carb)
During the afternoon:
Regular water intake
10-20 minutes before practice:
Half a banana or small energy snack
This rhythm supports sustained energy, emotional stability, and consistent performance.
Why Fueling Juniors Properly Matters
Young athletes perform best when their bodies - and brains - have the right fuel. Proper pre-training nutrition supports:
Fueling juniors before training builds confidence, prevents mid-session crashes, and helps athletes enjoy the sport while performing their best.
When coaches and parents prioritise fueling juniors before training, athletes develop healthier routines and more consistent energy levels.
