Tennis is not just about forehands; it’s about energy management.

If you find yourself cramping in the third set or losing focus after an hour, the problem isn”t your fitness—it”s your fuel. For players over 40, reliance on just water and a banana is no longer enough. You need a “Technician”s” protocol.

Here is how to fuel your body like a Ferrari, not a Corolla.

Phase 1: Pre-Match (The Loading Phase)

Timing: 2-3 hours before the match. Goal: Fill the tank without bloating.

Eat a meal rich in complex carbohydrates and moderate protein. Avoid high fat/fiber immediately before playing.

• Good: Oatmeal with berries, Chicken and Rice, Sweet Potato.
• Bad: Burgers, heavy cream sauce, raw salads (too much fiber).

Phase 2: During the Match (The Engine Room)

You lose sodium, potassium, and magnesium in your sweat. Water alone dilutes your remaining electrolytes, leading to cramps.

Liquid Fuel: LMNT vs Liquid IV

• LMNT: For heavy sweaters. Zero sugar, 1000mg sodium. It tastes salty but works like magic against cramps.
• Liquid IV: Contains sugar (glucose) which helps rapid absorption. Good if you need an energy kick.

Solid Fuel: The “Changeover” Snack

• Bananas: Classic for a reason. Potassium-rich, but takes 10-15 mins to digest.
• Energy Gels: Pure glucose. Hits your bloodstream in minutes. Save these for the middle of a tough second set.

Phase 3: Post-Match Recovery (The Repair)

The Window: 30 minutes after match point. Your muscles are screaming for glycogen and protein.

The Golden Ratio (3:1) Aim for 3 parts carbs to 1 part protein. Believe it or not, Chocolate Milk is scientifically one of the best recovery drinks.

Conclusion

Nutrition is the easiest “cheat code” in tennis. It doesn”t require hours of practice—just planning. Pack your bag with electrolytes and a recovery shake, and watch your third-set win rate skyrocket.
