What to Eat & Drink Before, During & After Tennis
You wouldn't put 91-octane fuel in a race car and expect peak performance. Yet most club players eat whatever's handy, drink when they remember, and wonder why they fade in the second set. Here's the fuelling strategy that actually works.
Pre-Match: The 2-3 Hour Window
Your pre-match meal is the foundation of your energy for the entire session. Eat 2-3 hours before you play — close enough that glycogen stores are topped up, far enough away that your stomach is settled. The goal is moderate carbs, a little protein, minimal fat and fibre.
Ideal Pre-Match Meals
- • Toast with peanut butter and banana (the classic — works for a reason)
- • Porridge with honey and berries (slow-release carbs + quick sugar boost)
- • Rice with grilled chicken and a small side of vegetables
- • Pasta with light tomato sauce (not creamy — cream slows digestion)
- • Smoothie: banana, oats, Greek yoghurt, honey (if you can't stomach solid food)
Avoid: High-fibre cereals (gas, cramping), greasy food (sits in your stomach), large salads (volume without energy), anything you haven't eaten before a match before.
During the Match: Little and Often
For matches under 60 minutes, water is sufficient. Beyond that, you need carbohydrates — your liver glycogen stores are limited to about 90 minutes of high-intensity exercise. When they run out, you don't just feel tired — your brain slows down too. Decision-making suffers, reaction time increases, and suddenly you're making errors on shots you normally put away.
Aim for 30-60 grams of carbohydrates per hour during extended play. That's roughly one banana plus a sports drink, or two energy gels, or a muesli bar and water. Eat at changeovers — your body needs 15-20 minutes to convert food to usable energy, so eating at 3-3 fuels you for 5-5.
Hydration: The Non-Negotiable
Dehydration of just 2% of body weight (1.5 kg for a 75 kg player) reduces tennis performance by 10-20%. Your serve speed drops, your movement slows, and your concentration evaporates. In an Australian summer, you can lose that 1.5 kg in under an hour.
| Temperature | Fluid Intake/Hour | Dehydration Signs | Notes |
|---|---|---|---|
| Below 20°C | 500-700 mL/hour | Thirst, dry mouth | Cool conditions mask fluid loss — you still sweat, you just don't notice it |
| 20-25°C | 700-900 mL/hour | Dark urine, headache | Sweet spot for tennis. Drink at every changeover even if you don't feel thirsty |
| 25-30°C | 900-1200 mL/hour | Dizziness, muscle cramps | Add electrolytes — water alone can't replace sodium lost through heavy sweating |
| 30-35°C | 1200-1500 mL/hour | Nausea, confusion, cessation of sweating | Extreme heat policy territory. Consider playing early morning or after dark |
| Above 35°C | 1500+ mL/hour | Heat exhaustion: clammy skin, rapid pulse | Tennis Australia suspends play above 40°C. At 35°C+, your body simply cannot cool itself fast enough through sweat alone |
The golden rule: if you're thirsty, you're already behind. Start hydrating 2 hours before you play (500 mL), drink at every changeover regardless of thirst, and continue for 2 hours after your session. For hot-weather tennis, read our complete guide to playing in the heat.
Post-Match: The 30-Minute Recovery Window
The 30 minutes immediately after playing is your golden recovery window. Your muscles are primed to absorb nutrients — glycogen resynthesis happens 50% faster in this window compared to 2 hours later. Miss it, and you'll feel the session in your legs for an extra day.
The Recovery Formula: 3:1 Carbs to Protein
Quick Options (Grab-and-Go)
- • Chocolate milk (genuinely — the ratio is perfect)
- • Greek yoghurt with granola and honey
- • Banana with a handful of almonds
- • Protein shake with a banana blended in
Full Meal (Within 2 Hours)
- • Grilled salmon with sweet potato and greens
- • Chicken stir-fry with rice and vegetables
- • Eggs on sourdough with avocado
- • Tuna pasta with olive oil and spinach

What the Pros Eat
Novak Djokovic
Gluten-free pasta with olive oil and vegetables, 3 hours before. Dates and dark chocolate during matches. Electrolyte drink with Himalayan salt.
Takeaway: Simple carbs + healthy fats. Nothing experimental on match day.
Ashleigh Barty
Vegemite toast with banana, 2 hours before. Muesli bars and watermelon at changeovers.
Takeaway: Familiar, comforting foods. Your pre-match meal is not the time to try something new.
Rafael Nadal
Fish with rice and vegetables, 3 hours before. Energy gels and bananas during play. Salted water and sports drink alternated.
Takeaway: Lean protein + complex carbs. Alternating water and electrolytes prevents both dehydration and hyponatraemia.
Pack Your Bag Right
The best nutrition plan in the world fails if you leave everything in the kitchen. Here's what should live in your tennis bag permanently — pack it the night before and stop making excuses.
Water bottle (750 mL minimum)
Pre-fill and freeze half the night before — it'll be ice-cold through the first set
Electrolyte tablets or powder
Plain water dilutes your sodium levels. One tablet per 500 mL in hot conditions
Bananas (2)
Potassium for cramp prevention + fast-release carbs. Nature's energy gel.
Muesli bar or energy bar
For matches over 90 minutes. Look for 30-40g carbs, under 5g fat — fat slows digestion
Dried dates (small bag)
Djokovic's secret weapon. 75g carbs per 100g, plus potassium and magnesium. Packs flat in any bag.
Small bag of salted nuts
Post-match protein and sodium replacement. Cashews and almonds are ideal.
Cooling towel
Drape on your neck at changeovers to lower core temperature and reduce sweat rate
A proper tennis duffle bag has insulated pockets for bottles and food — keep everything cool and accessible. Pair it with a cooling towel for hot sessions and you've got a complete courtside nutrition station.
Pack Smart, Play Better
Bags with insulated compartments keep your nutrition plan intact from car to court.
