Exam 4 Body Composition Flashcards
Define Body Mass Index (BMI
A measure of body weight relative to height that is used to compare body size with a standard
BMI formula
weight in pounds/ height in inches^2 X 703
What BMI’s are considered underweight, healthy weight, overweight or obese
Underweight; 17-18
Healthy weight: 19-24
Overweight; 25-29
Obese: 30-39
Why is BMI not a perfect indicator of health risks
BMI is not a perfect indicator of health risks because it’s not actually a measure of body fat
What other methods can be used to measure body composition
underwater weighing, skinfold thickness, air displacement, bioelectric impedance
What are acceptable % of body fat levels for males and females
Males: 8-19%
Females: 21-32%
T/F? There are no health risks associated with being underweight
False: Being underweight is associated with increased risk of early death, but not all thin people are at risk. Low body fat due to starvation, eating disorders or a disease process decreases energy reserves and the ability of the immune system to fight disease
