  1. Body Composition Mr. Vecchio Health 2012

  2. Body Composition • Relative % of body fat to lean body tissue • No single weight for every person • Rationale- threshold level of body fatness above which health risks increase • Body Weight = not a good predictor of body fat (lean mass variations) • Men 25% and below • Women 32% and below

  3. BMI Chart

  4. Influences on Body Composition • Calorie Intake- calories taken in - calories expended • Metabolism- resting metabolic rate • Heredity- Inherited from parents (easier/harder to lose weight) • Physical Activity- Increases metabolism during/after

  5. Evaluating Body Composition • Skin Fold Measurements- subcutaneous fat at 8 sites (tester skill) • Bioelectrical Impedence (hydration) • Circumferential Measurements (simple) • BMI (groups) • Hydrostatic Weighing (most valid)

  6. Making Changes • Exercise (cardio burns fat, resistance builds lean muscle) • Diet (Balanced) • 1-2 lbs per week gain/loss is healthy non-water weight
