The last whistle signals the end of the game. All the goodbyes
are said. Now you are looking forward to the next soccer season.
Fine-tuning your soccer skills in the off-season is essential to
gain that competitive edge. Setting off-season nutritional goals
will help provide you with the tools you need to excel at your sport
during the next season.
Your off-season may consist of weightlifting, playing indoor soccer
or concentrating on another sport. There are several basic nutritional
guidelines that will help maximize your training potential. Understanding
your caloric needs will help you shift gears from the rigors of
competition to the demands of off-season training.
Calculating your calorie needs requires three steps:
- Changing your weight in pounds to kilograms
- Choosing the correct equation from Table 1
- Choosing the correct Activity Factor from Table 2
|
STEP 1:
Divide your weight in pounds by 2.2 to convert to kilograms.
Example: A 140 pound, 15 year-old male athlete
would weigh 64 kg.
STEP 2:
Choose the correct equation from Table 1 and do the math.
Example: (17.5 x 64) + 651 = 1771
1771 calories per day is called the Resting Energy Expenditure
(REE)
STEP 3:
Choose the correct Activity Factor from Table 2 and do the math.
NOTE: Review the Activity Levels definitions and choose the one
that fits best.
Example:
- In-season Extremely Active 1771 x 2.4
= 4250 calories needed per day
- Off-season Moderately Active 1771 x
1.7 = 3011 calories needed per day

ACTIVITY LEVEL DEFINITIONS
SEDENTARY:
consists of mostly sitting, watching TV, reading and using the computer
with no regular exercise.
LIGHT:
consists of eight hours of sleep and 16 hours of sitting or standing.
Three of the 16 hours must include light activity such as walking,
golf, and one hour of moderate activity such as table tennis, dancing
or walking 2.5-3 mph.
MODERATE:
consists of working in light industry where carrying, pushing, pulling
is a main part of the day. Or you can participate in regular exercise
four times per week for at least 40 minutes in duration.
VERY ACTIVE:
consists of participating in regular vigorous sports such as jogging,
or playing racquetball four times per week for more than 60 minutes
in duration.
EXTREMELY ACTIVE:
consists of training for athletic competitions such as soccer, basketball,
wrestling, climbing, distance running or weightlifting for at least
five times per week for at least 90 minutes or more in duration.
For soccer players who want to eat like champions during the season
or in the off-season, keeping a Food Inventory of your daily calorie
intake will provide useful information. Check the food label for
calorie information. If you are eating too few calories during the
season you may end up losing weight and strength, causing poor performance
on the field. Injuries and illness often accompany inadequate calorie
intakes. The number one nutritional problem seen in soccer players
is not taking the time to eat enough food to cover their high energy
requirements. Consuming adequate amounts of calories each day will
ensure the soccer player has energy to spare regardless whether
it is in-season or off-season.
NOTE: If you want to gain weight during
the off-season then add 400 calories each day to the diet you are
already consuming and hit the weight room.
PERSONAL OBJECTIVES
BURNING FAT
If your goal is to burn fat, you must exercise at a lower intensity
for a sustained period of time. During the first few minutes of
exercise, your body uses easily accessible carbohydrates for energy.
Only after the first few minutes does your body begin to use stored
body fat for energy. Because this process uses oxygen, your exercise
then becomes "aerobic." Although any form of physical
activity will help you to burn fat, aerobic exercise is by far the
most effective.
TONING THE BODY
To tone your body and build endurance, exercise at a medium intensity
for a moderate period of time. Your muscles must be pushed to a
moderate percentage of their capacity in order for them to be toned.
Be sure to rest on the day following each workout.
DEVELOPING MUSCULAR STRENGTH
Your muscles will grow stronger when increased demands are placed
upon them. To develop greater muscular strength, you must push your
muscles to a high percentage of their capacity by exercising at
a high intensity for a relatively short period of time. Then, rest
on the day following each workout so that your muscles can rebuild.

UNDERSTANDING NUTRITION & EQUIVALENTS
PROTEIN (12%-15%) -- some example equivalents for
1 meal
- 6-8 egg whites
- 200-300g skinless chicken breast (or
turkey)
- 200-300g lean red meat (inside round,
eye of round, flank)
- 1 can of tuna (water packed)
6-8 oz.
- 1-2 cups of low fat cottage cheese
- 1 low fat peanut butter sandwich
- 1 cup of beans (e.g. with rice)
|
Your body uses protein as the building blocks to produce muscle.
Proteins are composed of amino acids that your body arranges into
specific components to produce what it needs. Without protein you
would quickly lose muscle mass and definitely would not be able
to increase what you have.
To determine the number of protein grams required, divide your
body weight (in pounds) by 2 and multiply
by:
- 1 if inactive
- 1.3 if moderately active
- 1.5 if extremely active
|
CARBOHYDRATES (60%-70%) -- some example equivalents
for 1 meal
- 1-1.5 cup(s) of cooked rice (try accompanying
it with beans: see proteins)
- 1-1.5 large potato(s)
- pasta
- half-1 cup oatmeal (raw)
or 1 bowl carbohydrate/fiber cereal.
|
Carbohydrates are the primary source of energy that your body
requires. However, if you take in too many of these then your
body can't use
all of the energy, and what is left over gets converted to fat.
If, on the other hand, you are exercising a lot and not eating
enough
carbohydrates you will feel lethargic and tired all of the time.
FAT (20%-30%)
Fat is very important. We need a certain amount of fat every day
for proper metabolic function, such as cell integrity, hair growth,
etc. However, too much fat in one's diet will most likely lead to the body not using it
all and instead end up storing it. Fat is the body's best source of energy.
Unfortunately, unlike carbohydrates, your body doesn't readily use
it and prefers to store it for later use, when you are really short
of energy such as in starving mode.
WHAT ABOUT SALADS?
The word "salad" can be a bit misleading, if not particularly specific.
What is certainly important, and in addition to the suggested protein,
carbohydrate and fat equivalents, is to get
some green vegetables with your meals twice a day, if possible,
to get vitamins and minerals that your body requires to perform
important
metabolic
processes
so that you will be able to function at maximum level.
HOW MUCH EXERCISE
Barbara A. Brehm, Ed.D.
To maximize the health benefits of your exercise program,
you need to include the right amounts of the right kinds of activities
in your program, including:
AEROBIC ACTIVITY
Aerobic exercise challenges energy production systems. Our bodies
adapt to exercise demands by improving these systems. Benefits include
improved fat metabolism and higher levels of HDL cholesterol (the
"good" kind associated with reduced risk of artery disease).
Greater insulin sensitivity (cells respond better
to insulin) results in better blood sugar regulation,
which also reduces artery disease risk. Regular aerobic exercise
reduces the tendency of blood platelets to clump together, thus
decreasing the likelihood of dangerous blood clots. The heart becomes
a more efficient pump and beats more slowly at rest. Aerobic exercise
requires energy expenditure; we burn calories that might otherwise
be destined for storage as fat.
RESISTANCE TRAINING
When we apply force against a resistance, such as elastic bands
or a stack of weights, our muscles, bones and joints adapt by becoming
stronger. Denser bones are more resistant to osteoporosis, and stronger
muscles and joints are less prone to injury.
STRETCHING
Adequate joint flexibility prevents injury and chronic musculoskeletal
problems, such as low-back pain. Like strength, flexibility declines
as we age. Regular stretching can slow this decline and reduce that
stiffness that keeps us from enjoying activity.
