Being lean is important as body fat
needs to be oxygenated. Having high body fat means that you have a lower
percentage of oxygen going to your heart, brain and muscles essentially
diminishing your V02 max. Second, the more fat you have the lower your
strength to body weight ratio is meaning you have less functional
strength and speed on the pitch. Lastly, fat is not just an unsightly
inert reservoir of energy that sits on your love handles.
Fat
releases a number of chemicals that can affect your appetite; and create
inflammation and insulin resistance. They release chemicals that clot
your blood, increase your blood pressure and narrow your arteries and
they convert male hormones to female hormones, which is not good if you
are a man.
Good human nutrition encompasses eating regular meals,
with good sources of protein, lots of vegetables and cutting out junk
foods that are touted as "performance foods."
Food provisions at breakfast
Eating breakfast is paramount for football players. A study published in the European Journal of Clinical Nutrition
in 2010 demonstrated that of over 4,000 UK secondary school children 32
percent did not eat breakfast and were more likely to be overweight and
obese. The content of a healthy breakfast is debatable with the
government, mass media and many sporting bodies promoting junk foods as
healthy "sports nutrition". The Nutrition for Football Conference held
at FIFA House in Zurich in September 2005included common breakfast foods
such as cereal with milk, flavoured yoghurt and fruit smoothies in its
list of nutrient-rich carbohydrate foods.
The Australian institute
of Sport also recommends foods such as crumpets with jam or honey,
flavoured milk, baked beans on toast and breakfast cereals as healthy
pre training breakfasts and snacks. These foods are indeed carbohydrate
rich, however what seems to be completely missed is these foods are high
in processed sugar, contain gluten, dairy and other common food
intolerance's and are generally poor providers of essential fats,
protein, fibre, vitamins and minerals.
Better examples of healthy
breakfasts include porridge, scrambled eggs on whole grain (preferably
gluten free) toast, an omelette or some meat or fish with nuts and
vegetables.
Food provisions at lunch and dinner
Various
researchers have estimated the calorie intake of footballers to be
between 2,600 and 3,952 calories a day. Considering that The Department
of Health recommends a calorie intake of 1940 calories per day for women
and 2550 for men, it seems football players don't necessarily need to
consume a great deal more than the average person.
Conventional
nutrition advice is for a high carbohydrate, moderate protein and low
fat diet for footballers; however this dietary advice leaves a lot to be
desired. The over reliance on carbohydrates, particularly starchy and
processed carbohydrate such as potatoes, pasta and rice, can leave
players with high body fat, high cholesterol and problems with insulin
sensitivity. There may also be nutrient deficiencies due to the huge
demand on the body for zinc, magnesium and B vitamins to convert food to
energy and for other nutrients that act as antioxidants that won't be
provided by nutrient deficient processed carbohydrates. Functional
nutrition and medicine testing has demonstrated this time and again in
elite football players.
A priority for evening meals is to avoid things that retard, and do things that promote good quality sleep. This includes:
- Avoid drinking caffeine in the evening.
- Don't over hydratein the evening, as you will wake to urinatein the night.
- Eat some starchy carbohydrate as this helps to raise serotonin and melatonin that aid sleep. Good choices include vegetables such as swede, carrots, squash, sweet potato, whole grain rice and quinoa.
- Eat magnesium containing foods as magnesium aids sleep. These include green leafy vegetables, nuts, seeds and fish.
- Don't eat high sugarfoods before bedsuch as sweets, candy, dried fruits or desserts.
- Eat good qualityprotein at dinner, especially proteins that contain tryptophan and taurine (seafood, scallops, lobster and poultry).
Food
allergy and food intolerance's are becoming more widely recognised
amongst nutritional and conventional medical practitioners. Avoiding
food intolerance's can promote good body composition and quality sleep.
Common
food intolerance including diary, wheat, soy and yeast cause an immune
response that can manifest as low grade "silent inflammation" with sub
clinical symptoms such as brain fog, irritable bowel, headaches or low
energy. Research from the Clinical Institute of Medical and Chemical
Laboratory Diagnostics in Austria has shown that obese children have
significantly higher antibodies against certain foods than normal weight
children. These antibodies are associated with thickening of the common
carotid arteries. The authors state that these findings raise the
possibility that food antigens are involved in the development of
obesity and atherosclerosis.
Snacks
Snacking
is a great way to control energy levels and get additional calories and
nutrition in to the diet. However, snacking may not be needed by all as
some people can do really well on main meals and "sports nutrition" to
meet their daily nutrition and energy requirements.
Football
players need to focus on nutritious food such as fruit, nuts and seeds,
vegetable crudités and dips. Regarding "sports nutrition" you could eat
foods such as rice cakes, dried fruits, nut butter, and other spreads
that provide "carbohydrate" after intense training sessions and games.
Sports nutrition
One
of the biggest myths we need to overcome in football is the concept of
carbohydrate loading. Carbohydrate loading is perfect for marathons,
triathlons and other long distance events; however it is not needed for
football especially when you get your nutrient timing right. On that
note, some of the nutrition advice previously given to athletes to
carbohydrate load including the consumption of toast and jam, jelly
beans and sugary soft drinks seems obsolete, clearly we know these foods
are full of carbohydrate but they are devoid of other essential
nutrients needed for elite performance and may even lead to the
accumulation of excess body fat, which in itself may hamper performance.
Nutrient timing after games
Nutrient
timing is the consumption of specific fluids and nutrients pre and post
games to enhance performance and recovery. Some research suggests this
is best done with protein and carbohydrate beverages, but food is
important as well.
Before a game eat a sensible breakfast or lunch
as previously discussed and hydrate well. During a game staying
hydrated with water and consuming some carbohydrate drinks such as
Cherry Active, Vita Coco or Lucozade lite is essential.
After a game you can follow these recommendations:
- Within 30 minutes post training or a game drink a protein shake with a 4:1 carbohydrate / protein solution.
- Within 30 - 120 minutes posttraining or a game eat a meal containing carbohydrate such as potato, sweet potato, squash or dried fruit, however, limit the use of grains. Also eat some meat, fish, seafood or poultry and some healthy fats such as avocado, olive oil, nuts or seeds.
- Within 2 - 4 hours post training or a game snack on some fruit or dried fruits, nuts and seeds.
Hydration
Dehydration can have a serious negative effect on performance. As little as 2% dehydration causes:
- 8% loss of speed
- 10% loss of strength
- 20% loss of cognitive function
Drinking water is
usually the first line strategy to replace fluids lost through sweat.
Adding electrolytes to your drink is also a great way to replace salt
and water lost in sweat. These include sports drinks such as lucozade
lite, a product called Elete or VitaCoco.
