H2Owesome Round III
- Alex, Michael, Kelsey
2
Importance of H2O
- Regulation of body temperature
- Allows for cell growth and reproduction
- Carries nutrients to cells
- While carrying waste away
- Lubricates joints
- Acts as shock absorber for vital organs
3
Importance of H2O
- But wait, More!!!
- delivers oxygen to cells
- Increases and decreases blood viscosity
- Major component in all body parts and cells
- Most Importantly Its better than Gatorade
- - The Waterboy
4
Growth and Maturation
- Growth
- CHANGE in size
- Either as a whole or the sum of the parts
- NOT necessarily an increase in size
- Maturation
- The process of becoming mature or progress toward
the mature state - The process of becoming an adult
5
Fat-Free Mass
6
Fat-Free Mass
- Chemical Maturity
- The point at which the concentration of water,
protein and minerals becomes comparatively
constant in the fat-free cell is named the point
of chemical maturity of the cell. - Maturity is the process of attaining adult tissue
function, quality and composition - Fat-free mass increases in solid components,
replacing the water component - Resulting in an increase in body density
7
Total Body Water
- Total Body Water (TBW) follows a growth pattern
like that of stature and weight - Rapid increase during infancy
- Gradual increase during adolescent
- Plateau at chemical maturity
- Males have greater TBW then Females across the
age range - TBW reaches a plateau for females sooner than it
does for males
8
Total Body Water
- TBW begins to plateau during the ages of early
adulthood - These levels are maintained throughout the adult
life - Until we reach older adulthood (gt65years)
- Fat-free mass then begins to decline
- Including TBW
9
Increasing/Decreasing Quantity
- Sources of Water
- Liquids (ex.-water)
- Food
- Metabolism
- Water Output
- Urine
- Feces
- Skin (sweat)
- Expired air
10
Increasing/Decreasing Quantity
11
Increasing/Decreasing Quantity
- In order to increase the quantity of water in the
body - We need to our fluid intake
- Increase foods in water
- (fruits veggies)
- Decrease foods in sodium
- With the exception of Chipotle (lets be real)
- Avoid hot/humid environmental conditions
12
Peak functional/Dysfunctional levels
- Average sedentary adult in a neutral environment
requires about 2.5L of water daily - However, this can change based on activity level
- Exercise physiology literature confirms the need
to consume fluid before and after physical
activity - A decrease in TBW can have negative influences on
physical performance
13
Peak functional/Dysfunctional levels
- Fluid loss coincides with the following five
factors - Decreased plasma volume
- Reduced skin blood flow for a give core
temperature - Reduced stroke volume (SV)
- Increased near-compensatory heart-rate
- General deterioration in circulatory and
thermoregulatory efficiency in exercise
14
Summary
- Water is critically important to the human body
and peak physiological function - Water is also extremely important in terms of
physical performance in physical activity,
exercise and sport - Dehydrations causes a decrease in physical
performance - So drink before, during if need be and after
exercise
15
Summary
- In Absolute terms TBW increases throughout
childhood and adolescents - In Relative terms () Water decreases as it is
replaced with more solid fat-free components
throughout childhood and adolescents - Water levels off in adulthood and then begin to
decrease as age increases - Older adulthood
