Physiotherapy – Fitness Testing and Prescription Lab Part A Body Composition (25 points) Body Composition Several methods are currently used to determine body fatness or percent body fat including: Simple methods (Ht/Wt charts; Body Mass Index) Hydrostatic weighing Skinfolds and anthropometric measurements Ultrasound Photon absorption Computed tomography Infrared interactance Electrical impedance Total body electrical conductivity Nuclear magnetic resonance imaging While the gold standard is still hydrostatic weighing, other models, which are based on a multiple compartment model, i.e. Dual energy x-ray absorbmetry – DEXA, are quickly emerging as accurate and reliable methods for the body composition analysis. Body mass index (BMI) We will be using skinfolds and body mass index as a means of measuring body composition. While body mass index (BMI) is simply based on height and weight (kg/m 2 ) and is a simple, fast means of body composition measurement, it tells us little (nothing) about lean muscle mass or body fat percentage and makes most lean individuals overweight simply by definition. Below are standards for grading obesity using BMI, you may also find a nomogram in the ACSM Guidelines book. Body Mass Index (Weight (kg) / Height (m 2 ) 20 – 24.9 Desirable 25 – 29.9 Overweight 30 – 40 Obesity > 40 Morbid Obesity Centers for Disease Control, Waist to Hip Ratio Waist to hip ratio is used to determine risk levels for various types of chronic disease including diabetes and coronary artery disease. A tendency to carry adipose around the torso predisposes an individual to high levels of LDL and glucose as well as hypertension (metabolic syndrome or Syndrome X). Male waist to hip ratio should be at or below 0.90 and
