How to Evaluate Body Size and Shape
continued
● Identify your body's patterns of fat distribution.
– Android Pattern
● "Apple" shaped
● Excess body fat on upper body and trunk
● Associated with greater disease risk
– Gynoid Pattern
● "Pear" shaped
● Excess fat mainly on lower body
(hips and thighs)
Assessing Body Composition
● Skinfold Measurements
– Use calipers to measure skinfold thickness
– Accurate assessments require experience and practice
● Dual-Energy X-Ray Absorptiometry (DXA)
– The "gold standard" for assessing body
composition
– Uses low-radiation X rays to distinguish body components
● Hydrostatic Weighing (Underwater Weighing)
– Requires an equipped facility
Assessing Body Composition
continued
● Air Displacement (Bod Pod)
– Measures total body air displacement
– Used with other measures for a full
assessment
● Bioelectrical Impedance Analysis (BIA)
– Measures resistance of tissues to electrical
currents
– Accuracy depends on machine quality and
participant cooperation
How Can I Change My Body Composition?
● Determine if your percent body fat is within a
healthy range.
● Set reasonable body composition goals.
● Follow a well-designed exercise and nutrition
plan.
