Under Water Weighing
Error Not consistent
w Body density Body mass Body volume
w Body mass is measured on land.

• Body volume
• Measured using hydrostatic (underwater) weighing
  
• Accounts for water density and air trapped in
  lungs

w 2-3 margin of error
This is an information slide with animated arrow
and font differences.
5
Skinfold fat thickness
Error Too wordy

• Percent body fat is determined from the
  relationship between skin fold thickness and body
  density.
• From skin fold thickness a formula is used to
  calculated body density. The body density is then
  used in another formula to estimate percent body
  fat.
• The equations used to determine body density and
  percent body fat need to be gender, age and race
  specific.
• With skinfolds there is a 3-4 error compared to
  under water weighing
• Other errors occur from not measuring skin folds
  at the correct location, pinching the skinfold to
  hard, not pinching a true skinfold, using
  inaccurate calipers, etc.

Bioelectric Impedance

• Measurement of body water.
• Impedance or (resistance) decreases with body
  water.
• Assumption that body water is at a constant
  value.
• 3-4 error

Air Plethysmography
Autoshape
Error Not aligned
BOD POD

• Similar principle as UWW
• Air instead of water
• Comparison
• Error 2-3
• Costly
• Convenient for subject
• Low tech skills

Duel-Energy X-Ray Absorptiometry (DEXA)

• Developed to measure bone density
• Can measure bone, non-bone, and fat density
• New gold standard?
• Comparison
• Error 1-5 (software)
• Very costly
• Very high tech
• Quick, subject friendly
