Powerade™ - Does It Really Have Power? by Jennifer G.Galea
MS RD
Most athletes know the
importance of adequate
hydration. But did you know
that some people could lose
3.5 to 4.5 pounds (1.5 to 2
liters) of fluid per hour? And
that as little as one percent
loss of body weight during
exercise will impair
performance?
How do you achieve
adequate hydration? First,
you need to ensure that you
are fully hydrated when beginning exercise.To do this, the
recommendation is to drink 12 to 20 ounces (400 to 600 ml) of
fluid, 2-3 hours before exercise, in addition to drinking generous
amounts of fluid throughout the day.
During exercise, athletes
should drink enough to maintain fluid balance (to take in as much as
they are using and sweating).To
obtain this level of hydration, the recommendation is to drink
6 to 12 ounces (180 to 360 ml) of fluid at 15-20 minute intervals,
beginning at the start of exercise.
But what type of fluid should
you consume? Should it have sugar and if so,what kind? Should it have
sodium? Do you really
need a sports drink?
According to current recommendations,
you should not drink beverages containing “fructose” during exercise, which means
that you should not consume fruit juice. But do you need
anything more than water? For intense exercise lasting more
than one hour, experts agree that your beverage should contain
both carbohydrate and sodium.The carbohydrate level
recommended is 4-8%.This level aids in appropriate gastric
emptying (passage through the stomach) as well as replacing
blood sugar/muscle glycogen. Sodium is important because it
may enhance the palatability of the beverage and the “drive to
drink”, with the end result being an increase in fluid consumed.
Despite the recommendation
of drinking regularly during vigorous exercise,most athletes do not
consume enough fluids
to compensate for their losses.This results in their bodies
being dehydrated. Sports drinks, such as Powerade™, are more efficient
in reducing post-exercise dehydration. It contains sodium
which aids in rehydration by maintaining plasma osmolality
(concentration of the blood), which helps maintain the desire
to drink.
So yes, a sports drink is definitely a better choice than water for
optimal hydration for athletic performance, especially if the
exercise is intense or lasts more than an hour. It’s important to
keep in mind that overall nutrition impacts on your hydration
status, so eat right and drink plenty of fluids even when your
aren’t in training.

Adapt
By Bill FitzPatrick In daily life, through a love
of many things, it is possible to
remain adaptable. If it starts
raining on the way to the
beach, you’ll enjoy going to
the movies. If you are kept
waiting for an appointment,
don’t get angry. Make a few
calls or work on your schedule. If you get
stuck in traffic, enjoy your favorite
motivational audiotape, radio station or CD.
Always have a book with you and you will
never be alone.The small stuff can’t get you
down if you are ready to substitute one good
thing for another.
personalProfiles Stephani, Age 11
My story starts with me standing
on the steps to the dojo. I was so afraid,
I could not move. Mrs. Sherwood
had to come downstairs to help me
into the class. I was the new student
in class. Then I started to go more
often and I liked it every time. I look
forward to every class. I’m 11 years
old and a blue belt. I am also a member of the Black
Belt Club. I love martial arts and I’m proud to be in
the class. I have been training for one and a half years.
I had a sledding accident
at my friend’s house. I had a
hairline fracture in my collarbone. My arm was in a
sling for three weeks, which meant I could not
participate in class. The doctor x-rayed my shoulder
and said it was healed. It was very hard to go back to
class. I was afraid that I would hurt my shoulder again.
My family and the instructors helped me to get back
into class. I’m very thankful to have all of them in my
life. Karate is a big part of my life and I love the
people who helped me get back to where I am today.
I would like to dedicate my
story to Instructor Marston who is in the hospital getting well. We
all miss you at
the school. Get well soon.
