To boost athletic performance, it is very important to understand what good recovery means! Recovery is multifactorial and can be different for different people, but this page covers two important areas: diet and sleep

Studies have shown that many athletes do not get enough energy, i.e. food. An acronym used to denote energy shortage in athletes is “RED-S” (Relative Energy Deficiency in Sport). RED-S is characterised by impaired physical function caused by a lack of energy. This energy shortage can increase the risk of injuries, osteoporosis and stress fractures, worsen immune system function and impair athletics training as well as competition performance. As such, it is necessary for each individual to find the right energy balance to maximise their function and well-being.

You should strive to become, and remain, a healthy athlete. You should eat what you, the individual, needs (and enjoys) based on who you are and your personal needs, and not based on what others around you do, or do not, eat. If your goal is to perform better in athletics and you do not consume enough in the way of energy (food), do not rest enough, exercise too much and sleep too little, then your body will break down and your performance will be impaired. This can result in the most important goal of all, being a healthy athlete, becoming simply wishful thinking.

Diet – How should we eat when we exercise?

The purpose of eating is to produce energy, energy for living life. If a fairly large part of your life is athletics then you require even more energy to fuel both training and life in general.

An athletic youth normally has an increased need for energy and nutrition in comparison to young people who are not as physically active. To meet this need, it is important to eat sufficiently and have a balanced, well-varied diet. Meal planning is also particularly important to ensure performance and recovery for both training and competition.

Planning your diet around training or competition is crucial to getting the most out of these activities. The relationship between exercise and energy intake is important and therefore how you eat, what you eat and what time you eat is critical to performance. Because of this, it is important to plan your diet and exercise and to understand the effects this planning has.

Below are some examples of good dietary intake, appropriate timings for eating and the positive effects this can have (Berg, K, 2013).

Before exercise:

A larger meal can be eaten one to four hours prior to exercise, depending on the duration of the activity. It is also possible to consume a small meal just prior to exercise. The aim of eating prior to exercise is to optimise the carbohydrate supply within the muscles and liver so that supplies are sufficient for the upcoming activity. Protein intake prior to exercise improves the effect of the subsequent exercise and reduces the risk of muscle damage. Fluid intake before exercise gives improved hydration. A small meal just before exercise can ensure you feel comfortably full and can create a feeling that you are well prepared.

Examples of appropriate food for before activity:

  • A sandwich with butter & filling such as cheese / ham / turkey / cottage cheese / mackerel in tomato sauce / egg & 1 glass of milk
  • Yogurt & bran/corn flakes with extra nuts / seeds
  • Smoothie of yogurt & milk + berries & 2 slices of bread/ one sandwich with butter and toppings/fillings
  • 2-3 egg Omelette, or scrambled eggs, with bread (2 slices) & butter
  • Pasta salad with vegetables

During exercise:

An activity’s duration and intensity will influence what, if any, intake is required during the activity itself. If the activity lasts for more than an hour then extra intake may be necessary to replenish carbohydrates in order to maintain blood sugar levels and supply the muscles. This extra carbohydrate intake contributes energy to the ongoing exercise but also has a positive effect on the immune system, both during and after activity. An intake of carbohydrates in combination with protein is important for reducing muscle damage and increasing adaptation after exercise. This applies to both strength and endurance training.

After exercise:

An initial recovery meal can contain primarily simple carbohydrates, as it is these that break down easily in the stomach and intestines and raise blood sugar levels quickly. Protein should also be included as this inhibits break down of the body and initiates recovery. This meal ensures the carbohydrate supply is replenished and muscle damage is repaired and built up. Muscle breakdown decreases. The immune system’s function is enhanced and salt and liquid losses are replaced. After the initial recovery meal, a normal meal containing carbohydrates, proteins and fats can be eaten to aid carbohydrate replenishment and muscle recovery.

Examples of good recovery meals;

  • 400ml milk & raisins
  • Yogurt drink & a banana
  • 2 sandwiches with ham & 1 glass of milk
  • Smoothie made up of yogurt / milk / berries / fruit
  • 200ml yogurt topped with dried fruits & berries
  • 300ml juice & 400ml milk
  • Yogurt with cornflakes & raisins

Sleep – why do we need sleep?

Sleep is critical to recovery!

When we sleep, the body’s temperature, pulse, stress hormones and blood pressure go down. On top of this, the muscles relax and the immune system is activated, which means that the body heals and recovers. When we sleep the body also produces important hormones that make us feel better during the day.

Increased hormone production during night time is one of the reasons children and teenagers should sleep more than adults, as it is during night time that growth hormone is produced!

How much sleep we need depends on how long we have been awake and how long, and how well, we have slept during the preceding nights. Sleep requirements can vary from 6 & 1/2 to up to 9 or 10 hours a night. Young people under the age of 13 need around 10-11 hours sleep per night, whilst teenagers need between 9-10 hours sleep. A good night’s sleep means that we fall asleep relatively quickly and wake rarely, or not at all. Sleep deprivation can greatly reduce quality of life and often has negative consequences for sports performance.

Temporary sleep deprivation does not affect gross motor functions such as muscle strength and endurance. However, it can impair so-called psycho-motor functions such as mood, reaction time and concentration. The longer the sleep deficit lasts, the greater the effect. Many athletes find that their performance deteriorates dramatically due to acute sleep deprivation. This may be due to the fact that sports performance relies on both good decision-making and physical ability, and that results are influenced by mood and motivation.


Common questions:

What food is good to eat after exercise?

In order to aid build-up and recovery it is beneficial to eat something immediately after training that both reaches your muscles quickly and that can inhibit their breakdown. As an athlete, you will benefit from replenishing the carbohydrate supply in your muscles quickly, by consuming simple carbohydrates, but also from consuming protein which will speed up muscle recovery. A good example is a large glass of milk and one or two bananas.

What should I do about breakfast if I want to train early in the morning?

If you have an early training session or competition you can consider eating an extra evening meal the night before. This is so your muscles have some energy supplies left in the morning. Then, before your morning session, you can top-up with something easy to digest. It would be ideal if you woke with sufficient time to eat a hearty breakfast but, in reality, this isn’t always practical due to fatigue and / or lack of time. Getting up in time to eat properly is, nevertheless, recommended if you are doing strength training or a more intensive session. If the session is lower-intensity and shorter it may be sufficient to eat a snack such as yogurt or milk and some fruit.

Does the family have to eat two cooked meals every day?

The recommendation to eat two cooked meals a day is based on the fact that such meals often contain a better balance of fats, carbohydrates (including fiber) and protein, as well as greater amounts of vitamins and minerals, due to the inclusion of more vegetables. In reality, however, it can be at least as good, and less stressful, to eat a meal that is quicker to prepare but still contains these important elements. For example, you can save both time and energy by eating porridge with jam, cinnamon and milk along with one or two liver pate and cucumber sandwiches. If you supplement this meal with fruit or juice and perhaps an egg, then this will be nutritionally better than a cooked meal that, for example, is made up of pasta, sausages and ketchup.

Do I need to consume extra protein in order to get enough and to build muscle?

You do not get larger and stronger muscles from consuming an excess of protein. You build muscle through exercising optimally and eating enough energy in the form of fat, carbohydrates and protein. Within this the timing of protein intake is important. The body absorbs protein during the day’s meals as long as you eat regularly and enough. A well-balanced meal (with carbohydrates and protein) before exercise, combined with a recovery meal (containing protein) eaten immediately after exercise is enough. No additional supplements such as protein powder or protein bars are required.
