Nutrition
and Supplements for Athletes
By Sandra Brown
Nutrition
A
good healthy diet will give you vitality, protect your immune system from
infection and illness (avoiding time lost from training and racing), promote
recovery from races, training and injury, and generally keep you in good shape
for life and sport. It needn’t be costly to eat well for health - rich,
expensive food, and alcohol are not your best bet!
Fruit
and Vegetables
Eat 5-10 portions daily of fruit and vegetables, including a wide variety. Mix
up the colours, as different coloured fruit and veg (eg, red, yellow, green,
black) contain different vitamins and minerals, and make their own different
contributions to your health. Broccoli and all types of cabbage, red, green and
yellow peppers, and carrots and other root veg are all very good. Apples and
oranges are traditional health favourites, and bananas are a particularly good
source of potassium (to counteract the effect of sodium and help prevent high
blood pressure.) Dark fruits, which are common in autumn, are thought to help to
fortify the immune system for
winter. Dried fruits (dates, figs, prunes, apricots, raisins, bananas etc) are
rich in vitamins, minerals and fibre, and easy to carry around as snacks.
Protein
Ultra distance athletes need more protein than normally recommended amounts,
for general well-being, muscle maintenance and repair, injury prevention and
recovery. Fish of all kinds is excellent. Eat plenty of low fat yoghurt, fromage
frais, cottage cheese, for their calcium content as well as protein. Enjoy a few
mixed nuts each day. Lean meat is also fine. Eggs and cheese are very
nutritious, and especially useful after races.
Soya
is marvellous, as a source of protein and for its antioxidant and health -
giving properties. Plain tofu is quick and versatile - no need to cook unless
you want to. TVP is a useful soya product. Soya milk is nice but mostly water.
Soya and other bean dishes are useful, tasty and health-boosting for vegetarians
and non-vegetarians alike. Vegetarians especially can help to ensure they get
sufficient iron by eating iron-rich fruits and veg (including broccoli and
green, leafy veg,) wholemeal bread and cereals, taking brewers yeast or a B
complex vitamin supplement, and enjoying small amounts of Vegemite or other
yeast extract spread.
Carbohydrates

Athletes need
carbohydrates - including bread, cereals, potatoes, rice, pasta - for energy, to
keep muscles fuelled, and to support muscle maintenance and repair, and to
support the immune system especially after hard training and long races. If you
don’t eat adequate carbs, the body will run down muscle, and the immune system
will suffer. A word of warning; don’t assume you need very large amounts of
carbs - the amount you need depends on your size and training volume. A good
intake of fruits/veg and of protein are both more important to your health than
carbs, and both will provide energy. Too many carbs can mean too little of
important nutrients, and can lead to unwelcome weight gain if you eat too much
for your training/racing energy needs. Too many refined carbs, sugary foods and
foods with a high glaecemic value, can lead to energy peaks and troughs, and
even contribute to borderline diabetes, so choose non-sugary and unrefined carbs,
don’t eat too much at once, and combine carbs with protein, fruit and veg.
Fats
Be
fairly sparing with fats, and be selective. Some fat in the diet is important to
health and to the absorption of vitamins; choose monounsaturated fats like olive
oil and peanut butter for preference. Try to avoid saturated and hydrogenated
fats in food and cooking (visible meat fat, butter, margarine, cream and most
fats sold for cooking.) Substitute vegetable oils (especially olive oil, as in
the Mediterranean diet) and use them for all salad dressings and in baking. Just
substitute olive oil for other fats in your baking, cakes, scones, etc -
it works! Don’t fry food, or dry fry with a minimum of oil. Instead of putting
butter/margarine on bread, get used to the taste of bread on its own, or use a
little honey, jam, vegemite, cottage cheese or quark instead.
Salt
Most people consume far too much salt, to the detriment of their health.
Salt is a major contributory factor to raised blood pressure and hypertension.
Don’t add it to food in cooking or at the table (you will soon adjust to a
different and more subtle taste.) Avoid salty snacks, which are often also
fatty. Training and racing will lower your resting pulse rate and blood
pressure; for most people this is good news. Reducing salt intake will help in
this. You don’t need to replace salt which is lost through sweating - little
is lost in this way, in fact, and the body has ample reserves. If, after a long
race, you feel a desire for savoury foods, especially if you have been taking in
lots of sweet food and drink, then enjoy them, and take the chance to eat some
protein, but don’t pile on the salt. Cravings like this are the body’s way
of restoring and rebalancing its levels of energy, protein, vitamins, and
minerals.
Drink

Drink plenty, much more than you probably think is needed! Drink a pint or
so of water or very diluted juice/squash/energy drink before you go out
training, and drink some more when you return. Get into the habit of drinking
tea weak, and generally cut down on tea and coffee if you usually drink a lot -
your system will feel cleaner and healthier for it. Substitute water,
juice/squash preferably well diluted, and try herbal teas. Use skimmed milk, and
drink as much as you like for its calcium and vitamins. Now for the boring bit!
At parties, try to stick to juices and soft drinks mainly, and at dinners
develop a taste for fizzy water. Red wine may be good for the immune system, but
moderate exercise is even better, and for most athletes is their preferred
route. If you like wine and it agrees with you, allow yourself one or two
glasses occasionally. Avoid alcohol the night before a race. The night after a
race, enjoy a beer if you want to. I personally find that exercise and alcohol
don’t mix too well, and in general, I put exercise first.
Race
Food/Drink
Before training or racing, drink plenty. Avoid food for 2-3 hours before a
race; if th e race is a short, hard one (even up to the marathon), most athletes
prefer to race empty, to avoid stomach upsets. Energy drinks, and simple foods
like bread and cereal if they suit you, are useful to fuel up before a morning
marathon or half. If a race is in the afternoon, eat an easily digested
breakfast, then rely on drinks and perhaps a sandwich, cereal bar or chocolate
bar in late morning, to top up.
During
ultra races, you need to eat and drink. Find out what works for you. Some race
organisers put out food that some experienced athletes would not eat, so don’t
assume that if something is provided, it must be sensible and effective to eat
it! You need carbs which will go down easily and not cause digestive problems,
as well as some protein if the race lasts for 24 hours or longer. Not all
athletes take protein during races of 24 hours. I find that some protein in the
form of cheese, nuts, rice pudding, peanut butter sandwiches, results in my
feeling stronger throughout a race, especially during the second half when many
people begin to fade, and also leads to quicker recovery and a better, healthier
feeling after the race is over. In any race beyond 24 hours, I would attach
importance to an adequate, regular intake of protein as well as carbs.
What
you can eat may depend on your pace. If you are pushing hard, you may be more
restricted in what food you can tolerate than if you are going steadily. In
general, be careful about pushing too hard in long races. It is easy to get
carried away and go too fast in the early stages, then regret it when you feel
tired and rough later on!
With
food and drink, it is a good idea to take a little and often, rather than to
overload the system with larger, less frequent amounts. Some organisers provide
real meals three times a day. In a multiday race, walking round the track slowly
while you eat a meal, or even taking a break to eat, may provide a valuable rest
and do you good. In a 24 hour race, however, it may be best to snack on small
portions (eg a bit of potato and cheese, or pasta,) or to leave full meals to
the supporters.
In
a 24 hour race, start drinking early and keep drinking at sensible intervals
until the end. Try to start eating small amounts regularly after the first hour
or so; if you have not had a meal for some hours you will feel you need
something. How often you eat is up to you, and may vary with the amount you take
(eg a mouthful every 10-20 mins, or a sandwich every 30-40 mins) and with the
size of the lap on a road course. On a lap of 5 miles, you may not get the
chance to eat and drink often, so be ready to take something every time you pass
the feeding station.
During
the first few hours of a 24 hour race, you may not feel you need to eat, and
during the last 12 hours, you may not feel you can. In the early hours, try to
make yourself eat a little regularly - you will be glad later, and be at
less risk of suffering the physical and mental lows which come from depleted
energy reserves, and which can creep up on you. Time and again I have seen even
experienced athletes on a high and going strong in the afternoon, forget to eat
and hit a wall in the evening or the night, when coldness increases their sense
of depletion. If you forget to eat, or cannot eat, and begin to feel low on
energy, slow, shivery, and weak, take action quickly: get additional, warm
clothes on, and have a warm, sweet drink, and some food which is tempting and
digestible and will give you a boost, such as chocolate and cake. Keep moving to
keep warm and to keep your circulation going, but slowly enough to digest the
food and to rebuild your energy and confidence - a steady walk for a few
minutes may be ideal. Then eat some more, and make sure that you do not forget
again! If you have a supporter, they should be on the lookout for the danger
signs, such as refusal to eat when a snack is scheduled. If you see another
athlete in trouble - wandering on the track or road, looking pale or goose-pimpled
- tell their handler or the organisers.
Learn
from experience what you can tolerate, and what feeding strategy gives you the
best results. If you have a bad race - for example with stomach problems, cramp
or muscle pain, low energy, feeling cold or faint - analyse carefully afterwards
what might have caused the problem. What did you eat and drink during the 1-2
days before the event, in the hours before the start, and during the race? Could
something have upset you? Did you go into the race dehydrated, or get dehydrated
during the race; if so, this is a sure recipe for any or all of the problems
listed above! We are all different. I personally thrive on a mixture of easy
carbs (eg sandwiches, malt loaf, mashed potato, rice pudding, porridge/cereal)
and some protein (eg small cubes of cheese, nuts, peanut butter) in small
quantities as needed, which may vary from every 30-60 mins, usually more
frequently in the second half of a race. I don’t eat fresh fruit during 24
hour races - even bananas - however much I enjoy fruit in everyday life.
Sports
drinks don’t suit everyone; don’t feel you should necessarily use them
because others do, or that you are at a disadvantage if you don’t like them.
Find out what does work well for you.
Just
because something is called a sports drink and is provided at races, and even if
it used successfully and endorsed by other athletes, don’t assume it must work
for you, and don’t keep using a drink that causes you problems (I have seen
athletes who do this.) The salty nature of some electrolytic drinks can cause
stomach upsets and cramps; and even long-chain, complex carbohydrates (eg
maltodextrins) can challenge the digestion and cause sickness. I know some
runners who seem to tolerate quite concentrated mixtures of energy drinks and
even protein drinks, especially if they are drinking water as well. Some people,
me included, can use such preparations only if they are well diluted, and more
dilute than the manufacturers’ recommendations.
There
are alternatives: I have had good races using coke (regular, not -diet- nor
defizzed - the fizz can help sort out the stomach,) Lucozade (original, not the
sports variety which I find too concentrated and salty,) and ordinary orange
squash, well diluted.
Dehydration
is dangerous: be alert for any feelings of dehydration, and if they occur, drink
more frequently. Don’t wait until you are thirsty: drink at regular intervals,
depending on your pace and the weather conditions. Judge carefully how much to
drink to keep yourself in balance. When the temperature cools down at night, or
if your pace slackens, consider reducing the liquid intake (eg to 2 rather than
3 drinks an hour, or taking smaller amounts.) Watch out for signs of
overdrinking - needing to urinate too often (it wastes time!), bloating and
sometimes sickness. But never deny thirst: if you need it, drink!
After
a long training session or race, especially an ultra, it is vital to take in
carbohydrates and protein, to replace energy, support the immune system (which
is vulnerable to infection and chills at this time,) and to kick-start the
repair and build up of muscle. Try to have some carbs and some protein (eg
cereal with banana, milk and yoghurt; sandwiches with peanut butter, cheese, egg
or other protein) within 15-20 minutes of finishing a race or training session.
Organisers do not always provide for such nutritious snacks at the finish of a
race. I usually try to have something in my bag that I know will travel well and
will suit me, such as a sliced malt loaf or sandwich, some cheese or a
hard-boiled egg, an apple or dried fruit, and a bottle of water in case
organisers’ supplies dry up.
After
a long race, your muscles will have suffered a lot of damage, and your system
will be flushed with debris resulting from muscle and tissue breakdown. You need
additional protein for several days to help the repair and building process. You
also need plenty to drink, again for several days after a long race, to help the
body to flush out debris and waste, and to carry nutrients to areas needing
repair. Good sleep at night promotes repair. You are like a building site, and
need to assist the flow of materials and the speed of construction! The quicker
the repairs are carried out, the sooner you can train effectively and compete
safely and successfully again.
Supplements
Even if you
maintain good general nutrition, consider taking the following daily also:
Multi vitamin and multi mineral (one a day type, fairly high strength, but no
need to buy special ones, eg marketed for athletes, busy people, or women);
vitamin C 500 or 1000 mg; cod liver oil or other fish oil; evening primrose oil
500 or 1000 mg; lecithin 1000/1200mg; vitamin E; brewers yeast; odourless
garlic; calcium / magnesium combination providing 1000 mg calcium (some contain
zinc and/or boron and/or vitamin D also.)
For
times when you feel under pressure with signs of infection or when the immune
system is depressed, eg for a day or so after a long race , have the following
available to use as needed: echinacea (herbal); aconite (homeopathic); selenium
(mineral); zinc (mineral). All are powerful reinforcers of the immune system. Do
not take them continuously; keep for when needed. Good natural sources of zinc
which can be enjoyed anytime include grapes, some nuts and dried fruit.
There
are homeopathic remedies for all kinds of conditions; look at the charts in a
chemist or health food shop.
The
other great booster of the immune system is vitamin X - exercise, most
effective in boosting the immune system at moderate intensity for around 30
minutes daily. Most ultradistance athletes will want to exercise for longer than
this; this is fine if you are conditioned to it and provided you stay well. If
you are not used to it, build up gradually and carefully. Listen to your body.
If you feel tired and/or unwell, back off. If you are just tired, walk or run
easily for up to 30 mins, but be ready to ease off or stop if you feel you
should. Otherwise, just go for a pleasant walk or rest; don’t strain. Be kind
to yourself whenever you are off colour, and your body will appreciate it. There
is always another day, and it is daft to prolong illness or injury by training
when you shouldn’t; don’t feel guilty. When you are feeling better, try a
gentle bike ride on the road or exercycle, a walk, or other moderate exercises
at home to get you back into the swing.
