Fuelling Stamina in Tennis: The Link Between Diet and Performance 

Fuelling Stamina in Tennis: The Link Between Diet and Performance 

With an estimated 60 million players worldwide, tennis is one of the most physically demanding sports. Unlike other sports with set game durations, tennis matches can range from under an hour to over five hours, placing extreme mechanical and physiological stress on the body. As a result, maintaining stamina is crucial for peak performance, and diet plays a significant role in achieving this. 

The Unique Stamina Demands of Tennis 

Tennis is a high-intensity, stop-and-go sport. A single point can last anywhere from 4 to 10 seconds, followed by around 20 seconds of active recovery between points and 90-120 seconds of rest between changeovers. Despite these short bursts of effort, matches can last hours, leading to significant declines in speed, power, and accuracy over time. Studies have shown that stroke velocity, running speed, and muscular force decrease as match duration increases, with accuracy dropping by up to 81% in long matches. 

How Nutrition Supports Tennis Stamina 

Given the unpredictable duration and energy demands of tennis, players must strategically fuel their bodies before, during, and after matches to maintain stamina, prevent fatigue, and speed up recovery. 

Pre-Match Nutrition: Carbs Are King 

Carbohydrates are the primary energy source for tennis players. Studies show that players prioritise carbohydrate-rich meals before matches, with popular choices including: 

• Oats, cereals & eggs for morning matches 

• Pasta & sandwiches for afternoon matches 

• Whole grain pasta & brown rice for sustained energy release 

Carbohydrate intake 3-4 hours before a match enhances intestinal absorption and ensures steady blood glucose levels, helping to delay fatigue and maintain performance. 

During the Match: Hydration & Quick Energy 

Sustaining energy and hydration during matches is crucial. Research found that most players consume multiple food and drink sources during match play, including: 

• Water (94%) – Essential for hydration and preventing cramps 

• Bananas (86%) – A quick source of glucose and potassium 

• Sports drinks (50%) – Help replenish electrolytes lost through sweat 

• Other snacks – Figs, dates, BCAAs, fruit-based snacks, and even small amounts of jelly for fast-digesting sugars 

This strategic fuelling helps maintain energy levels, delay muscle fatigue, and optimise endurance during prolonged matches. 

Post-Match Recovery: Replenish & Repair 

Recovery is just as important as preparation. After intense matches, players focus on replenishing glycogen stores and repairing muscle damage. Post-match nutrition habits vary, with: 

• 34% opting for carbohydrate-dominant meals 

• 26% consuming protein shakes 

• 19% choosing balanced meals 

However, availability and practicality often influence food choices, especially during travel. Many players rely on what’s accessible at venues or local dining spots, highlighting the need for portable, nutritious recovery options. 

Ergogenic aids : Supplements That Boost Performance 

While a balanced diet is key, some tennis players turn to ergogenic aids. Supplements that enhance performance and recovery. The most effective include: 

• Caffeine (3 mg/kg an hour before matches) - Boosts alertness, muscle contractility, and endurance. 

• Creatine (3 g/day for at least 4 weeks) - Supports the growth of lean mass and muscular strength, aiding in explosive movements and quick recovery. 

• β-alanine (3.2-6.1g/day in divided doses) -Helps buffer acid buildup in muscles, delaying fatigue.  Improves muscle contraction and endurance. 

• Sodium Bicarbonate (900 mg/kg pre-match) - Also assists in balancing the acidity in muscles and prolong exhaustion. 

Final Thoughts: Eat Like a Champion 

Tennis is not just a test of skill and endurance, it’s also a test of smart fuelling strategies. From carb-loading before a match to staying hydrated and refuelling with protein post-match, a well-structured diet can make the difference between fading in the final set or staying strong until the last point. Whether you're a weekend warrior or an aspiring pro, understanding the science behind nutrition and stamina can help you bring your a-game to the court, every time.
