Body Composition What is Body Composition The percentage
Body Composition
What is Body Composition? • The percentage of body fat to lean body mass. • Lean body mass: – Bone – Water – Muscle – Connective tissue – Organ tissue – Teeth • Pound for pound, muscle weights MORE than Fat!
Fat vs. Muscle
How to use Body Composition. • Determine what Body Composition is right for you. • Then work to achieve and maintain it. • Your scale weight shouldn’t be your focus… • Instead, focus on your Body Composition!
Different methods of assessing your Body Composition • • • Body Mass Index (BMI) Skin fold Measurement Underwater Weighing The Bod Pod Bioelectrical Impedance Analysis (BIA)
Body Mass Index (BMI) • A measure of body weight relative to height. BMI can be used to determine if people are at a healthy weight, overweight, or obese. To figure out BMI, use the following formula: • A BMI of 18. 5 up to 25 refers to a healthy weight • A BMI of 25 up to 30 refers to overweight • A BMI of 30 or higher refers to obese.
Skin fold Measurement • The thickness of a skin fold is measured in three different locations on the body. • A sum of 3 measurements are taken and compared in a chart for men & women to determine the percentage of body fat.
Underwater Weighting • An individual is submerged and weighed underwater. • Body fat percentage is calculated from body density. – Muscle has higher density – fat has lower density • Fat people tend to float!
The Bod Pod • The BOD POD measures the volume of air a person's body displaces while sitting inside a comfortable chamber, rather than measuring how much water their body displaces when dunked in a tank.
Bioelectrical Impedance Analysis (BIA) • BIA sends a small electrical current through the body and measures the body’s resistance to it. • Fat-free tissues are good conductors. • Fat is not a good conductor.
