Why is water important?
"The Fluid Pyramid" is
a great indicator of how much fluid you should be drinking
- Keeps you cool through perspiration
- Perspiration is 99% water, but also contains
some electrolytes (salts)
- Enables the storage of glycogen, an essential
source of energy in one's muscles
- An increased metabolic rate during exercise
increases loss of water through perspiration and evaporation
- Athletes can lose up to a gallon of fluid
an hour during heavy exercise
- If you do not replace the same amount of
fluid you lose the body will start to protect itself by limiting
its activity
- In the hot weather, dehydration can occur
in 30 minutes if the body doesn't getting the amount fluid it
needs
- Signs of dehydration:
- feeling dizzy
- light headed
- having muscle cramps
- feeling nauseated
- having a headache
- 8-16 ounces of fast absorbing fluid should
be consumed 10-15 minutes prior to exercise
- At least 4-10 ounces every 15-20 minutes
during exercise
- 24 ounces after the activity
- Works as a solvent, transporting, combining,
and chemically breaking down substances
- Hydrolysis, the process of water breaking
down molecules, plays a key role in breaking down essential molecules
such as proteins and carbohydrates. During hydrolysis the H+
ions bonds with the negative part of the molecule and the OH-
ion bonds with the positive.
