ART-817: Nutrition for Tennis Performance
Executive Summary
Nutrition plays a critical role in tennis performance, recovery, and long-term health. The sport's intermittent high-intensity demands require adequate glycogen stores for energy, protein for muscle repair, and micronutrients for optimal physiological function. Effective tennis nutrition involves daily macronutrient planning, strategic hydration protocols, and tournament-specific nutritional strategies that fuel performance while minimizing gastrointestinal distress. Players who optimize their nutritional intake gain competitive advantages in energy availability, recovery speed, and mental clarity.
Macronutrient Requirements
Carbohydrates
Carbohydrates are the primary fuel source for tennis's high-intensity efforts:
- Training Days: 5-8 g per kg body weight per day
- Match Days: 7-10 g per kg body weight per day
- Recovery Days: 3-5 g per kg body weight per day
Sources: Whole grains, rice, pasta, bread, fruits, vegetables, potatoes, oats
Timing: Distribute across meals and snacks; emphasize pre-match (3-4 hours before), during-match (if applicable), and post-match (within 30 minutes) intake.
Protein
Protein supports muscle repair, immune function, and recovery:
- Daily Intake: 1.4-2.0 g per kg body weight per day
- Distribution: 20-40 g per meal, 4-5 meals per day
- Sources: Lean meats, fish, eggs, dairy, legumes, protein supplements
Key Timing: Post-match protein within 30 minutes; protein before sleep for overnight recovery.
Fats
Fats provide essential fatty acids, support hormone production, and aid in vitamin absorption:
- Daily Intake: 0.8-1.2 g per kg body weight per day
- Focus: Unsaturated fats (omega-3s, olive oil, nuts, avocados)
- Limit: Saturated fats (fried foods, processed meats, full-fat dairy)
Daily Macronutrient Distribution (70 kg Player)
| Macronutrient | Training Day | Match Day | Recovery Day |
|---|---|---|---|
| Carbohydrates | 420-560 g | 490-700 g | 210-350 g |
| Protein | 98-140 g | 98-140 g | 98-140 g |
| Fat | 56-84 g | 56-84 g | 56-84 g |
| Calories | 2,800-3,500 | 3,100-3,900 | 2,100-2,800 |
Hydration Strategies
Daily Hydration
- Baseline: 35-40 mL per kg body weight per day (2.5-3.0 L for 70 kg player)
- Additional: 500 mL per hour of training or competition
- Monitor: Urine color (pale yellow indicates adequate hydration)
Pre-Match Hydration
- 3-4 Hours Before: 500-600 mL of water or electrolyte drink
- 1-2 Hours Before: 250-300 mL of water
- 15 Minutes Before: 150-200 mL of water
During-Match Hydration
- Changeovers: 150-250 mL of water or electrolyte drink every changeover
- Hot Conditions: Increase to 200-300 mL per changeover
- Electrolytes: Include sodium (300-600 mg per liter) for sessions over 60 minutes
Post-Match Rehydration
- Target: 150% of body weight lost during the match
- Method: Weigh before and after; replace each kg lost with 1.5 L of fluid
- Include: Sodium to enhance fluid retention
Hydration Benchmarks
| Hydration Status | Urine Color | Body Weight Change | Performance Impact |
|---|---|---|---|
| Well-Hydrated | Pale yellow | < 1% loss | No impact |
| Mild Dehydration | Yellow | 1-2% loss | 5-10% performance decline |
| Moderate Dehydration | Dark yellow | 2-4% loss | 10-20% performance decline |
| Severe Dehydration | Amber/orange | > 4% loss | > 20% performance decline, health risk |
Tournament Nutrition
Pre-Match Meal (3-4 Hours Before)
Goal: Top off glycogen stores without causing GI distress.
Composition: - Moderate-high carbohydrates (1-2 g per kg body weight) - Moderate protein (15-25 g) - Low fat and low fiber (to minimize GI distress)
Examples: - White rice with grilled chicken and steamed vegetables - Pasta with tomato sauce and lean protein - Bagel with peanut butter and banana
Pre-Match Snack (1-2 Hours Before)
Goal: Maintain blood glucose without overeating.
Examples: - Banana with a small amount of nut butter - Sports drink and a granola bar - Toast with honey - Energy bar with moderate carbs and low fat
During Match (if applicable)
Goal: Maintain blood glucose and hydration.
Options: - Sports drink (6-8% carbohydrate solution) - Energy gels (20-30 g carbs per gel, taken with water) - Banana (easy to digest, provides potassium) - Dried fruit (dates, raisins for quick energy)
Post-Match Recovery Meal (Within 30 Minutes)
Goal: Begin glycogen replenishment and muscle repair.
Composition: - 3:1 or 4:1 carbohydrate-to-protein ratio - 1.0-1.2 g per kg body weight of carbohydrates - 20-40 g of protein
Examples: - Chocolate milk (natural 3:1 ratio) - Protein shake with banana and oats - Turkey sandwich on white bread - Rice bowl with grilled chicken
Micronutrient Considerations
Iron
- Role: Oxygen transport, energy production
- Sources: Red meat, spinach, fortified cereals, lentils
- Risk: Female athletes and vegetarians at higher risk of deficiency
- Monitor: Annual blood tests (ferritin levels)
Calcium and Vitamin D
- Role: Bone health, muscle function, immune support
- Sources: Dairy, fortified plant milks, sunlight exposure (vitamin D)
- Risk: Indoor training, limited sun exposure, dairy-free diets
- Monitor: Bone density scans for at-risk players
Magnesium
- Role: Muscle function, energy production, sleep quality
- Sources: Nuts, seeds, leafy greens, whole grains
- Risk: Heavy sweating depletes magnesium
B Vitamins
- Role: Energy metabolism, red blood cell production
- Sources: Whole grains, meat, eggs, dairy
- Risk: Restrictive diets (vegan, low-carb)
Supplementation
Evidence-Based Supplements
| Supplement | Evidence | Dose | Purpose |
|---|---|---|---|
| Creatine Monohydrate | Strong | 3-5 g/day | Power, strength, recovery |
| Caffeine | Moderate-Strong | 2-6 mg/kg | Alertness, performance |
| Beta-Alanine | Moderate | 3-6 g/day | Buffering capacity |
| Vitamin D | Moderate | 1,000-4,000 IU/day | Bone health, immunity |
| Omega-3 Fatty Acids | Moderate | 1-3 g EPA/DHA | Anti-inflammatory, recovery |
| Whey Protein | Strong | 20-40 g/post-exercise | Muscle repair, recovery |
Supplements with Limited Evidence
- BCAAs (if protein intake is adequate, BCAAs offer minimal benefit)
- Glutamine (limited performance benefit)
- Testosterone boosters (ineffective and potentially harmful)
- Fat burners (risky, may contain banned substances)
Anti-Doping Considerations
- All supplements should be third-party tested (NSF Certified for Sport, Informed Sport)
- Players are responsible for what they consume
- Check all supplements against WADA prohibited list
- When in doubt, do not take it

|---|---|---|---|
| Energy crash during matches | Insufficient pre-match carbohydrates, poor during-match fueling | Fatigue, reduced performance | Increase pre-match carbs; introduce during-match fueling |
| Slow recovery between days | Inadequate post-match nutrition, poor sleep | Cumulative fatigue, reduced training quality | Implement post-match recovery protocol; sleep optimization |
| Frequent muscle cramps | Dehydration, electrolyte imbalance, poor conditioning | Cramping, time loss | Hydration protocol; electrolyte supplementation; conditioning improvement |
| Weight loss during tournament | Insufficient caloric intake, high energy expenditure | Fatigue, performance decline | Increase caloric intake; portable high-energy snacks; meal planning |
