BODY COMPOSITION Body Composition is the concept describing the relative percentage of muscle, fat and bone in our body. Body Composition analysis is a tool often used in the assessment of a person's state of fitness as it can tell us much about the physical characteristics of the person. Skinfolds Body Fat Percentage Equipment: Skinfold calipers. Disadvantages: Results are subjective and rely on testers skill with calipers. Procedure: Four site method: Biceps, Triceps, Subscapular and Suprailiac (Durnin & Womersley). Take three skinfolds at each site and find an average for the site. Write the average mm skinfold value down for each site and add them all together, to get a "sum of skinfold measurements" in mm. Before each site is measured tense the muscle underneath and then relax the area (the arm readings are done with arms by side). Take the reading after a normal breath out. Male testers should be aware of the ethical considerations of testing females. Do this accompanied with another female if possible.

BMI
	Equipment: Calculator, metre ruler, weights scales. Target Population: Everyone who accepts being weighed! Advantages: Very little equipment needed. Disadvantages: Results are only rough indicators and do not take into consideration excessive muscle mass for particular sports. Procedure: Multiply your height in metres by itself to obtain a square metres value (example: 1.6m x 1.6m = 2.56 m2). Now divide your mass in Kilograms by this figure to find your BMI score.
Mass (70 Kg) / Height Squared (2.56 m2) = 27.3 BMI Ratings 20-25 25-30 30-35 Ideal Weight Slightly Overweight Overweight
