About Tennis

Tennis is a bat and ball sport played between 2 people (singles) or 4 people (doubles). Tennis is played internationally by both males and females, across a range of ages and levels of competition from recreational to professional elite level.

Matches are played over a number of sets – typically 3 sets but males also compete in matches played over 5 sets at major tournaments. In the professional level such as the Australian Open, matches can last up to 3 hours for women and 4-5 hours for men – although there have been situations of matches going much longer than this. Between each point players may only get a very brief break (~20 second). There is also a short (90 second) break with change of ends and 2 minutes between sets.

Competition play involves repeated short bursts of high intensity running over a match that can last for many hours. This means that tennis is a sport that requires not only a high level of skill and co-ordination but also a well developed anaerobic energy system and excellent aerobic capacity.

Therefore even though the match is not continuous it has the potential to challenge the athlete’s stored carbohydrates (glycogen). This becomes even more of a challenge during tennis tournaments when more than one match is held in a day or over several days as the time available for the athlete to fully recover is limited.

Although tennis can be played year round, it is predominantly a summer sport so players also need to be tolerant to heat – especially if playing in the afternoon when temperatures and humidity can be high.

Professional athletes can spend more than 25-40 hours training each week. Training isn’t just court-based work, it also focuses on improving footwork, agility, strength training and running. At a recreational level the training times will vary with many athletes participating in tournaments and competitive matches with more sporadic training regimes.

Training diet

Training for tennis can be intense, setting athletes up for increased energy and carbohydrate needs. Nutrition plans therefore need to be periodised to match the training demands of the player. For example, a diet that is high in nutrient rich carbohydrate foods is crucial to provide adequate energy to maintain performance and promote recovery during periods of heavy training. At other times, when training loads are lighter, energy and carbohydrate needs are also reduced accordingly.

Individual nutrition requirements will be determined by training load, specific athlete needs, training goals, body composition goals, health and adjustment for growth in younger athletes. Overall, training nutrition should focus on a combination of lean proteins for muscle repair and recovery with nutrient dense carbohydrate (appropriately timed for fuel). In addition, fruit, vegetables, nuts, seeds and wholegrains provide important vitamins and minerals, along with some healthy fats.

A body composition with a relatively high muscle mass and lower body fat levels is ideal for tennis players for powerful shots, speed and agility. Excessive restriction is not useful as this can compromise performance – players with a desire to change their body composition should work closely with an Accredited Sports Dietitian to develop an individual plan.

Hydration needs for tennis

Staying hydrated is important for playing tennis as the intensity of matches, as well as hot weather conditions can lead to high sweat rates (and fluid loss). Adding further challenge, the timing of matches can be unpredictable making it more important to constantly focus on good hydration strategies.

Since dehydration can impair performance, skill and decision making sipping on fluids (particularly water) regularly and aiming for a pale yellow urine is a good starting point.

During training and matches, having fluids easily accessible and making the most of opportunities to drink will help to replace sweat losses.

What to eat before a match

It’s important to matches well-fuelled and hydrated. The timing of matches can be unpredictable which can be a challenge for knowing when to eat a pre-match meal. In general having a pre-match meal ~3 to 4 hours before the start of the match then topping up with small snacks if needed is a good approach. The pre-match meal should contain some carbohydrate for fuel as well as some fluids for hydration. Some suitable ideas include:

  • Wrap or sandwich with ham and salad
  • Bircher muesli or porridge with fruit
  • Pasta with beef mince in tomato-based sauce
  • Chicken noodle soup served with bread rolls
  • English muffins with avocado and cheese

Additional snacks should be rich in carbohydrate but relatively low in fat and fibre so it is easy to digest. Some suitable snack ideas include:

  • Yoghurt
  • Fruit salad or fresh fruit
  • Dried fruit and nut mix
  • Rice cakes with peanut butter and banana

If solids don’t sit well before a game, or players are very nervous, a liquid source of carbohydrate such as a fruit smoothie or liquid meal replacement can be a good option.

What to eat and drink during a match

As tennis matches are often played in hot conditions, replacing fluid losses and keeping cool at breaks in play is important. In addition, carbohydrate can enhance performance and delay the onset of fatigue.

Practical hydration and cooling strategies include:

  • Add ice to bottles and store in eskies to keep cool
  • Use individual bottles to keep track fluid intake
  • Choose higher electrolyte fluids as the sodium content promotes rehydration.
  • Use cool towels around the neck and face
  • Sit in front of fans during breaks if possible

Depending on the length and intensity of the match athletes will need to remember to pack suitable fluids and snacks in their bag to have courtside so that they can make the most of any breaks in play to refuel and rehydrate. Suitable snacks include fruit, muesli bars or sandwiches with honey or jam.

Many athletes don’t like to eat whilst they are playing as they find the food can sit in their stomach, in these cases, specialised sports foods such as gels, energy bars and sports drinks can be useful as they digest rapidly.

Players should work closely with an Accredited Sports Dietitian to trial nutrition strategies during training and matches to find which foods work best for each player.

Post-match recovery

If players have less than 8-12 hours between training sessions or are playing in a tournament setting with multiple matches across a number of days then they should prioritise recovery nutrition as soon as possible after finishing the match

Recovery meals and snacks should contain carbohydrate (fuel), protein (for muscle repair and development) and plenty of fluids and electrolytes to replace sweat losses. Plenty of vegetables should also be included to complete nutrition recovery and support gut and immune health.

Some recovery food suggestions include:

  • Egg salad sandwich
  • Flavoured milk + handful trail mix
  • Wraps with chicken, cheese, avocado and salad
  • Pasta with bolognaise sauce and side salad
  • Homemade pita pizzas with ham, cheese + veggies


Other Nutrition Tips

  • Be prepared Unexpected situations (e.g. rain, long previous game) can delay the start of matches. It is a good idea to have a back up store of carbohydrate rich foods in your tennis bag so that you can top up fuel stores as needed while you wait.
  • Increasing muscle mass Young athletes who are still growing should aim to get meet their nutrition and protein needs from carefully planned and timed meals and snacks rather than supplements.
