Why is Good Nutrition
Important?
Without the correct
nutritional support the player will not be able to sustain an intensive
training program over a long period of time and improvement will, therefore, be
limited.
An understanding of nutrition is also necessary to ensure
optimum performance in competition, with manipulation of the diet leading to
substantial improvements in performance. The difference between the
skills and fitness characteristics of the winning and losing teams can often be
small and, where other things are equal, attention to diet can be the
difference between the team at the top and at the bottom.
Nutrition
and Foods
It’s important that the components of nutrition are known and a good
balance maintained for proper health and endurance. These components
consist mainly of:
·
Carbohydrates
·
Fats
·
Proteins
·
Vitamins
·
Minerals
·
Fiber
·
Water
The food and drink that we consume contain a variety of these
nutrients and it is essential that the right balance is achieved on a daily
basis in order to optimize performance.
The foods that we consume play three major roles within our
bodies:
·
Providing
energy– Almost all our bodily functions rely on the energy
contained within the foods we eat and drink.
·
Assisting
in growth and repair– Body tissues are constantly being broken
down and regenerated. This is achieved by utilizing the foods we eat and
is especially important when players are injured.
·
Maintaining
general body function– As well as providing energy to train and
compete, the daily needs of individuals must be met in order to maintain the
function of our biological systems, for example the heart, lungs and stomach.
For the soccer player, ensuring the diet contains sufficient
energy to meet the daily requirements is most critical. When considering
whether a player’s diet is “healthy” or “balanced,” many nutritionists believe
that if the correct amount of fuel is provided by the right proportion of
nutrients, then enough of the other essential nutrients will also be provided.
What to
Eat and when
The competitive year for the soccer player can be divided into three main
phases: the close season, the pre-season and the playing season. We will
briefly consider the nutritional habits of soccer players during each of these
phases:
·
Close
season– Energy intake of a soccer player tends to greatly
exceed energy expenditure. Activity levels decrease and there is little
attempt to modify eating habits accordingly, leading to increased body-fat.
·
Pre-season–
Energy expenditure greatly increases and energy intake is reduced to lower
body-fat. This is likely to adversely affect a player’s ability to
play. Energy intake and expenditure should match during the close season.
·
Playing
season– Energy intake appears to equal energy expenditure for
most players, but the contribution of the macronutrients, protein, fat and
carbohydrate to total energy can change to improve recovery and support
playing.
Understanding
Carbohydrates
Carbohydrates and fluid intake should be the main consideration for soccer
players as glycogen (stored carbohydrate) depletion and dehydration are two
major causes of fatigue during soccer training and matches.
Foods that contain carbohydrate are listed below:
Breads and pizza bases
Rice, pasta
and noodles
Potatoes and
potato products
Peas, beans,
lentils and corn
Fruits
(fresh, dried and canned)
Sugar, jams,
honey and fruit spread
Biscuits,
cakes and buns
Fruit
yogurts and other puddings
Soft drinks
and commercial sports drinks
Carbohydrate can be divided into two main categories: complex
(starchy) carbohydrate found in foods such as rice, pasta, bread and potatoes
and simple (sugary) carbohydrate found in fruits, jams and honey. In
reality, most of the foods we eat contain a mixture of simple and sugary
carbohydrate, for example cakes, buns, biscuits, breakfast cereals and
puddings.
To ensure that a soccer player’s diet is high in carbohydrate
and is also “balanced,” a mixture of carbohydrate-rich foods and drinks should
be consumed. This variety will help the player to consume adequate
quantities of other nutrients such as protein, vitamins, minerals and fiber.
During training, a player may need as much as five to seven
grams of carbohydrate per kilogram of body mass per day, with a little more
during intense training periods and in the 24-hour period after matches.
The immediate recovery period post training and matches is a
crucial period during which the depleted muscle carbohydrate stores can be
replenished at a faster rate than normal. It is recommended that
immediately post training players consume one to two grams of carbohydrate and
then the same again two hours later.
It’s difficult to achieve the recommended intake of
carbohydrate from only three meals a day. Therefore, snacking should play
a crucial role in a soccer nutrition program. The size and timing of
these snacks and whether they are in fluid or solid form will depend upon the
individual.
Consuming
a Low-Fat Diet
It’s not necessary to totally eliminate fat from the diet. A certain
amount of dietary fat is essential to ensure good health.
The following recommendations are designed to help a player to
achieve a low intake of fat as well as a high intake of carbohydrate:
·
Base
every meal and snack around a carbohydrate-rich food
·
Meats
and sauces should accompany bread, pasta, rice, etc.
·
Use
some reduced fat alternative foods such as reduced-fat milk, spreads and
cheeses and choose lean cuts of meat
·
Grill,
bake or microwave food rather than frying or roasting
Consuming
Adequate Quantities of Fluid
The recommendation is to drink before, during and after training as well as
drinking as frequently as possible during a match. You should practice
drinking a little and often.
The following are some key hydration points:
·
Rehydration
is a major part of the recovery process after exercise, but little attention has
been placed by players and coaches.
·
There
is also an increased risk of heat illness in individuals who begin exercise in
a dehydrated state.
·
Rehydration
requires replacement of body water loss, but ingestion of plain water is not
very effective. Drinks should contain moderately high levels of sodium
and possibly some potassium.
Traditionally, sports nutrition research has focused on
running and cycling performance because of the ease by which research studies
either on a treadmill or bike can be controlled. However, the critical
influence that nutrition can have on soccer training and competition has now
been recognized. A diet that is high in carbohydrate and adequate in its
fluid content will ensure that the soccer player can support consistent and intensive
training, ultimately affecting performance.
