(Chapter 1) Unit 9 obesity to Underweight: Flashcards
BMI?
- Calculated by dividing weight in kilograms by height in meters squared
- Classifying adult weight status by body mass index
how to calculate BMI?
-Chris weighs 140 pounds and is 5 feet, 3 inches tall
To calculate Chris’s B M I:
- Determine his height in inches
- 5 feet × 12 inches per foot = 60 inches
- 60 inches + 3 inches = 63 inches
- Divide his weight by his height in inches
- 140 pounds ÷ 63 inches = 2.22
- Divide the result (2.22) by his height in inches again
2. 22 ÷ 63 inches = 0.035

Visceral fat ?
-is fat stored in the abdomen under the skin and muscle of the abdomen
Skinfold Measurement
Body fat content can be estimated by measuring the thickness of fat folds that lie underneath the skin. Calipers are used to measure the thickness of fat folds.
Bioelectrical Impedance Analysis (BIA)
Fat is a poor conductor of electricity and water and muscle are good conductors body fat content can be estimated by determining how quickly electrical current passes from the ankle to the wrist
Underwater weighing
The subject is first weighed on dry land; next he or she is sunbmerged in water and exhale completely; then his or her weight is measured. This is why
Whole-Body Air Displacement
Uses air displacement for determining percent body fat. Individuals sit in an enclosed for about five minutes while wearing tight-fitting swim suit and sap.
