Hydration Flashcards
What is the water body content for humans
60%
Water content of lean muscle tissue
75% water
Water content of adipose tissue
10% water
What 2 fluids make up the body’s water content
Intracellular fluid 65%
Extracellular fluid 35%
What 2 fluids mane up the extracellular fluid
Interstitial fluid 80%
Intravascular fluid 20%
What is osmolarity
Concentration of solute in a solution I fluid
Tonicity
How extracellular fluid can change the volume of a cell through osmosis
What is meant by hypotonic
More water outside, less solution inside
Water move into cell
What is meant by isotonic
Solution and water is balance
What 1s meant by hypertonic
High water in cell, Water moves out of cell
Which fluid movement is sweating an example of
Hypotonic
Name 2 electrolytes
Sodium
Potassium
Which electrolyte is responsible for maintaining intracellular
Potassium
Which electrolyte is responsible for extracellular
Sodium
What is euhydration
Normal level of hydration in the body
Hyper hydration
Excess level of body water
Hypo hydration
Deficit in the level of body water
What are the 3 States of fluid balance
Hyper hydration
Euhydration
Hypohydration
What 1s the name of the process of a hyper hydrated state to a euhydrated state
Dehydration
What is the name of the process of a euhydrated state to a hyper hydrated state
Over-hydration
What is the name of the process of a hypohydrated state to a euhydrated state
Rehydration
euhydrated
euhydrated
Plan to drink
Drink to thirst
List reasons why we asses hydration
Maximise training capacity
Help with weight category events
Ways to measure hydration
Urine colour
Blood plasma
What is the relation between body fat and water content
The higher the body fat the less the water content
Where is intravascular fluid found
In plasma
what percentage does performance impairment happen at
greater than 2%
what are 3 methods use to measure hydration
thirst perception
urine colour
body mass
negative of hyperhydration on athlete performance
GI (bloating)
increase body mass so less power : weight ratio
positive of hyperhydration on athlete performance
positive of euhydration on athlete performance
benefit perfromance
recommended
positive of hypohydration on athlete performance
decrease body mass
increase p/w ratio
short duration / weight catergory event benefit
negative of hypohydration on athlete performance
more than 2% = performance impairment
what factors affect total water conetnt
age
gender
training status
body comp
muscle mass
is there more fluid inside or outside of the cell
inside
ere mor
what is the process of intracellular hypohydration
water moves out the cell
cell becomes denatued / strink
what is the bodys response to an increase in temp
vasodialte
sweat
what is the bodys response to an decraese in temp
vasoconstriction
shiver
