Staying hydrated is key to successful
athletic performance.

3.  A dehydrated athlete cannot turn calories
into energy as quickly, which in turn leads to
feelings of fatigue, cramping, and lowered
endurance. These effects can last for days.
Dehydration also reduces the body's ability
to burn fat deposits and inhibits the blood's
ability to transport nutrients and electrolytes
to the muscles. The latter especially has a
direct impact on an athlete's performance.

4.  The medical profession has determined that
when an individual feels thirsty, that person
is already experiencing dehydration.
Therefore, every athlete must schedule
regular water intake at steady intervals
throughout the workout. Trainers often
recommend 8 ounces per 20 minute as a
base level. Athletes should also begin and
end a workout well hydrated but should
avoid drinking excessive amounts of water
immediately before intense activity.
