SKATERS
HAVE SPECIAL NUTRITIONAL NEEDS
First,
its important that skaters replenish nutrients depleted by skating.
Second,
its very important that skaters maintain optimal blood sugar
levels both before, during and post-exercise.
Finally,
it is important to have sufficient levels of anti-oxidants to
protect your body from free radical damage to the muscles and
cellular machinery that allows you to perform to your best ability.
The goals of nutritional care for skaters
are:
Ensure that skater is properly hydrated
during periods of active training and competition.
Provide adequate calories to meet growth
and development needs, if in youth and adolescent years, and
the extra needs of the physical activity.
Supply nutrients from food .
Instill sound nutrition principles and
practices that will last a lifetime.

EATING
HABITS
Design a meal pattern that fits your
daily cycle. Plan to eat several times a day using regularly
spaced meals and snacks to help meet caloric and nutrient needs.
Eat a diet rich in complex carbohydrates
(starches). Starchy foods such as pasta, breads, cereals, potatoes,
corn, peas and others provide a major energy source to fuel your
activities. These foods are also a source of fiber, vitamins
and minerals.
Drink sufficient fluids to stay hydrated
during training and competition periods - don't wait until you
are thirsty to drink.
Eat a diet that contains a variety of
foods from breads and cereals; fruits; vegetables; meat and meat
substitutes; and dairy foods. It is your best insurance for getting
needed nutrients.
Diet and training work together:
Diet supplies the needed fuel sources
and nutrients for physical activity.
Training improves the body's use of fuel and enhances muscle
glycogen storage.
BACK
PRE-COMPETITION
RULES
Eat lightly before an athletic competition.
Eat complex carbohydrates, keep protein
and fat intakes low since these slow digestion.
Avoid bulky foods. They may stimulate
bowel movements. Bulky foods include raw fruits and vegetables,
dry beans and peas and popcorn.
Avoid gas-forming foods such as vegetables
from the cabbage family and cooked dry beans.
Eat slowly and chew well.
Drink water to be adequately hydrated.
Drink 2 cups of cool water 1-2 hours before the event. Follow
this by drinking 1 to 2 cups of fluid 15 minutes before the event.
Avoid drastic changes in your normal
diet routine immediately prior to competition. Some athletes
prefer to use favorite foods which give them a psychological
edge.
BACK
POST-COMPETITION
RULES
Eat carbohydrate-rich foods and beverages
as soon as possible after competitionto replenish glycogen stores
quickly and get the athlete back into performance shape. Fruits,
juices, high carbohydrate drinks and pop are examples.
Replace fluids that have been lost. For
every pound that is lost, drink 2 cups of fluids.
Replace any potassium or sodium that
has been lost during competition or training by using foods.
Fruits and vegetables are excellent sources of potassium. Replace
sodium by eating salty foods. If activity has exceeded 2 hours
and is vigorous, a sports beverage will be helpful.
Return to your normal high carbohydrate
diet at your next meal.

HYDRATION
AND FLUIDS
Of all nutritional concerns for athletes
the most critical is proper fluid hydration. One of the key functions
of fluid for the skater is for body temperature control. Lack
of this element above all others can hinder performance and lead
to more serious complications.
A fluid loss of as little as 2-3 percent of body weight impairs
performance. Fluid losses of 7-10 percent of body weight will
lead to heat stroke and death. For a 150-pound person, a 2-3
percent fluid loss equates to 3 to 4 1/2 pounds of body weight.
Endurance athletes who are involved in physical activity for
more than an hour and a half can produce up to three quarts of
sweat per hour (a loss of 6 pounds).
Fluid replacement is a special concern for children involved
in skating or other sports activities. Children have lower sweating
capacity and tolerate temperature extremes less efficiently than
adults. Young children also produce more heat during exercise.
They take two to three days longer to get used to exercise during
warm weather. Keep the water bottle handy during all sports activities
for children.
Six Basic Rules for Fluid Replacement
Cool fluids are best (40 - 50o F).
Plain water, or sports drinks and diluted
juices that have 4-8 percent carbohydrate concentration, adequately
replace fluid for most athletes. On sports drink labels look
for carbohydrate contents of less than 20 grams per 1 cup (8
oz). Dilute fruit juice by mixing one part juice with one part
water. Beverages such as carbonated sodas, undiluted fruit drinks
and juices, and high carbohydrate supplements will slow absorption
ratesand are not useful for immediate fluid replacement.
Don't depend on thirst. By the time you
feel thirsty, your body already has started to dehydrate.
Weigh before and after an athletic event.
Replace 2 cups fluid for every 1 pound lost.
Sip water or dilute fluids. Skaterss
involved in competition or training for longer than one hour
may benefit by using cool, pleasantly flavored, lightly sweetened
beverages such as diluted fruit juices or sports drinks. These
beverages provide both a fluid replacement and carbohydrates.
Avoid caffeine-containing beverages and
alcohol.
BACK
CARBOHYDRATES
Carbohydrate-rich foods are the best
fuel sources for skaters. Sports nutritionists recommend that
about 55 to 65 percent of calories come from carbohydrates. Complex
carbohydrates such as starches should make up the majority of
carbohydrate fuel. Examples of starchy foods are breads, cereals,
pastas, starchy vegetables such as corn and potatoes, and dried
beans and peas. Fruits are also excellent sources of carbohydrates.
It is important to eat a variety.
Besides providing energy, carbohydrate-rich foods such as grain
and cereal products, fruits, vegetables, and legumes are excellent
sources of fiber. Vitamins and minerals are abundant in many
of these foods.
In a skating event, carbohydrates are the initial fuel source.
The body stores limited amounts of carbohydrates as glycogen.
Through physical training and a diet rich in complex carbohydrates,
athletes are able to store more glycogen and to use its limited
supply sparingly. The amount of energy available from glycogen
storage is about 1800 - 2000 calories. When stores run low, skaters
become fatigued and performance suffers.
BACK
FATS
Fats, the other important fuel source,
have twice as many calories as an equal weight of carbohydrate.
Training increases the body's ability to use fat as an energy
source so that glycogen can be spared. However, fats cannot be
used exclusively as a fuel. Some carbohydrates must always be
available as a fuel source. Body fat storage will vary from skater
to skater. Even in a fairly lean individual, there will be a
good energy source from stored fat. For example, a 150-pound
skater who has 10 percent body fat has about 62,000 calories
as stored energy. That's plenty of energy to fuel an event over
an extended period.
Since the body's fat storage is more than adequate to provide
extra energy from fat it is not necessary to get extra fat from
your diet. In fact, a diet that is moderately low in fat (no
more than 30 percent of total calories from fat) will not hinder
performance and will promote an eating style that will be beneficial
throughout life.
