Are
water breaks necessary during soccer practices?
YES!
But why?
2/3 of soccer athletes arrive at practice de-hydrated
Children absorb more heat from a hot environment because they have a
greater surface
area to body-mass ratio than adults - the smaller the child,
the faster they absorb heat
Children and adolescents may have a reduced ability to lose heat through
sweating
During prolonged exercise, children and adolescents frequently do not
have the
Physiological drive to drink enough fluids to replenish sweat losses
Youth athletes are easily distracted when they should be resting and
rehydrating
Some youth athletes may be under intense pressure to make a competitive
squad and
may not want to report feelings of heat distress or take the
appropriate amount of time
to rehydrate
Factors affecting De-hydration:
Games are held outdoors, often in high temperatures and humidity, on
large fields that
offer little or no shade
FieldTurf expends more energy on muscles
Games and practice sessions when players are confronted with extreme hot
and humid conditions
No medical / physiotherapists around
Mental alertness and skill performance declines with dehydration6 and
could be a factor
in injuries occurring late in matches and training sessions
Medical staff, parents, playersand coaches must understand that thirst
is not a good
indicator of a childs fluid needs, so children need to
drink on a schedule
Guidelines:
Players should try to limit fluid losses to 1-2% of body weight or less
Before prolonged physical activity, the child should be well hydrated
During the activity, periodic drinking should be enforced even if the
child does not feel
thirsty. Each 15-20 minutes the child or adolescent should
consume:
- 5 ounces of fluid for a player
weighing 90 lbs or less
- 9 ounces of fluid for a player
weighing more than 90 lbs
Recommendations:
Kids need to drink enough of the right fluids to minimize fluid losses during
activity. Flavored beverages that contain sodium (sports drinks) are preferable
because the child may drink more.
Research shows that lightly sweetened and flavored non-carbonated beverages,
like sports drinks, are preferred during exercise and are consumed in greater
volumes than water, diluted fruit juice or carbonated beverages
Research shows that fluids containing sodium chloride (sports drinks) increase
voluntary drinking by 90%, compared to drinking plain water.
In addition to replacing fluid, children also need to replace the electrolytes,
such as sodium, that are lost through sweat. Electrolyte replacement is
important to stimulate an adequate thirst mechanism, help the body hold on to
fluid, help prevent muscle cramps and to maintain sodium levels in the blood.
Immediately before and during activity, children should avoid fruit juices,
carbonated beverages, caffeinated beverages and energy drinks. Fruit juices
have a high sugar content that can slow fluid absorption, cause an upset
stomach,19 and may also lack sodium. Carbonated beverages, such as soft drinks,
can reduce voluntary drinking due to stomach fullness, throat burn when gulping
and lack sodium.
Energy drinks should be avoided because many contain caffeine and have high
carbohydrate concentrations which slows the emptying of fluids from the stomach
Noticeable de-hydration symptoms:
Irritability
Decreased performance
Fatigue
Weakness
Nausea
Headache
Muscle cramping
Dark yellow urine (or no desire to urinate)
Lightheaded feeling or dizziness
Difficulty paying attention
Recommendations:
Correct fluids
Electrolyte replacement
Child uses their own beverage container that they can keep cool during
the practice
Dehydrated player will have to work harder to maintain the same level of
intensity than
their hydrated teammate
