It’s
a thing called weight………
Weight
watching is a universal pastime for non athletes and athletes alike,
especially from those sports who have to make weight (boxing, judo,
jockeys) or those where there is a culture of thinking thin, dance,
figure skating etc.
For
those who are training and competing body weight can often be a
poor indicator of fatness. Changes in weight can be due to fluid
losses, food still being digested from the last meal and changes
in the level of muscle glycogen (every gram of glycogen is stored
with approximately 3g of water). Since training especially weight
training, increases muscle mass, skinfold measurements are a better
guide to fatness than body weight.
Although
many strive for thinness, elite athletes strive to achieve low body
fat levels for competition. There are clear performance benefits
to being light and lean in sports like triathlon, marathon running,
swimming and gymnastics. However, our body type is also affected
by genetics and each person has a different capacity for leanness.
In some sports performers are naturally small and light however
in others (lightweight rowing, boxing, judo, weightlifting), there
is often pressure to manipulate body weight and fat levels to make
weight.
In
desperation, some resort to rapid weight loss methods prior to weigh
in. Such methods include severe weight restriction, excessive exercise
and dehydration which can be dangerous and in the longer term can
result in poor health, psychological problems and disordered eating
or eating disorders. A smart athlete will choose a sport or category
better suited to their physique, where they can concentrate more
on performance and feeling good rather than being pre-occupied with
weight and fat loss.
Dangers
of Dehydration
Dehydration is often used as a quick way of making weight. Fluid
loss of even 2% of body weight (1.4kg in a 70kg athlete) will decrease
performance, especially in sports like rowing or boxing when there
is a combination of strength and endurance needed. Other side effects
include:
· Fatigue
· Cramping
· Nausea
· Poor co-ordination and reaction time
· Increased body temperature resulting in heat stress / exhaustion
Counting
calories??
The
emphasis has been to reduce fat intake as a method of reducing weight
as there is no doubt that too much fat in the diet increases the
risk of being overweight. Fats are energy dense (9 calories per
gram) compared to proteins and carbohydrates (4 calories per gram).
The fat we eat is also stored more efficiently in the body so by
reducing it is an effective method in promoting weight loss. However,
this does not mean that we can eat unlimited amounts of low fat
foods? Well it depends on how active you are. Most active individuals
can eat as much low fat foods as they like and stay lean but the
couch potato or those athletes who are injured or out of season
may need to adjust their intake. Balancing intake with output is
an important factor in weight loss for sedentary or moderately active
individuals. They don’t need to count calories but they do
need to eat moderate amounts of low fat foods rather than large
amounts. The same applies to athletes who need to maintain their
body weight below what is natural for them.
Ditch
the carbs??
Just when most athletes are accepting the importance of carbohydrates
to their recovery and performance along come low carbohydrate diets
such as the Zone or Atkins diet. These diets usually restrict the
choice of foods you can eat and make meal times more difficult because
there are some many rules to follow. The end result is that they
are low calorie diets dressed up as something else. At the start
you do not notice that you are eating much less, sometimes as low
as 900-1000 calories per day. Bingo, weight loss is achieved but
there is a cost for athletes. Following any low calorie or low carbohydrate
diet, increases the risk of muscle loss and fatigue and increases
the recovery time.
Ways
to weight loss or making weight.
Choose
a balanced diet and focus on moderate fat intake.
Eat
less energy (calories) than you burn in training or competition
to achieve a deficit and therefore a weight loss. Don’t crash
diet.
Learn
how to handle eating out socially and include treats. You should
become less obsessed about or even frightened of the occasional
splurge.
Have
a training programme that complements your weight (fat) loss programme.
If you need to make a specific competition weight, heavy weight
training may need to be reduced or balanced with aerobic training.
Be
wary of times when weight / fat will fluctuate more, usually while
injured or out of season. You will need to adjust your dietary intake
and training to suit.
Gradually
reduce weight by 0.5-1kg per week or 2-5mm of fat each week if using
the skinfold measurement.
Train not more than 2kg away from your competition weight.
Realise
the importance of avoiding dehydration and eating well in the days
leading up to competition. It’s part of the package and as
important as other training techniques.
So
for those who need to lose weight remember its going to take time.
Quick fixes are not the answer as in the long term performance and
long term good health can be affected.
