Typical Body Composition of an Adult Man and
Typical Body Composition of an Adult Man and Women
Body Composition Assessment Body Mass Index Waist Size Waist-to-Hip Skinfold Fat Ratio Measurement Bioelectrical Hydrostatic Dual X-ray The Bod Pod Impedance Weighing Absorptiometry
Distribution of fat Important factor in health • “Apples”- gain weight in abdominal area • Coronary heart disease • High blood pressure • Diabetes • Stroke • “Pears”- gain weight in hip area
Assessing Body Fat distribution • Waist Circumference >40 in men > 35 in women • Waist-to-hip ratio >. 94 men >. 82 women
Body Mass Index Definition • An index of a person’s weight in relation to height • Body composition not considered! Body weight (kg) height (m 2)
Body Mass Index (BMI)
BMI and Risk of Health Problems
Skinfold Measurements • Principle behind this technique is that the amount of subcutaneous fat is proportional to the total amount of body fat
Hydrostatic or Underwater Weighing • Displaces water to measure % fat • Volumetric procedure • Gold Standard
Bod Pod • Displaces air to measure % fat
Content Review • Define body composition and explain how assessed • Define body mass index and explain how it is calculated • Explain techniques for estimating percent body fat (i. e. underwater weighing, Bod Pod, skinfold measurements, and bioelectric impedance analysis)
