  • BODY COMPOSITION
    • Measuring body comp.
      • BMI
        • Height & weight comparison charts
          • 18.5 - 23.8 = good for women
          • 20.1 - 25.0 = good for men
          • W/(h*h)
      • Hydrostatic weighing
        • individual immersed in water. results obtained by comparing scale weight to underwater weight. difference = %  body fat
      • Skinfold callipers
        • subcutaneous fat = estimate % body fat
          • Triceps
          • Subscapular
          • Biceps
          • Suprailiac
    • Somatotypes
      • Mesomorph = muscly e.g. Body builder
      • Ectomorph = very thin e.g. Marathon runner
      • Endomorphs = very large e.g. sumo wrestler
    • BAHL
      • higher percentage of body fat = higher risk to certain health issues
        • Myocardial infarction
        • Obesity
          • Shorter life expectancy
        • Type 2 diabetes
        • osetoporosis
        • Stroke/CHD
      • Obesity
        • Shorter life expectancy
      • Energy intake
    • BMR = Basal Metabolic Rate
      • BAHL
        • higher percentage of body fat = higher risk to certain health issues
          • Myocardial infarction
          • Type 2 diabetes
          • osetoporosis
          • Stroke/CHD
        • Energy intake
      • rate of energy expenditure
      • physical activity
      • Diet
      • Metabolic Equivalent Tasks (METs)
        • oxygen consumption per unit of body mass per minute
          • BMR = Basal Metabolic Rate
            • rate of energy expenditure
            • physical activity
            • Diet
