Select the correct option
Answers
Answer:
Body shape varies from person to person, and the shape of your body provides information about your body fat (4Trusted Source).
Measuring the circumference of certain body parts is a simple method of body fat estimation.
For example, the US Army uses a body fat calculation that simply requires an individual’s age, height and a few circumference measurements.
For men, the circumferences of the neck and waist are used in this equation. For women, the circumference of the hips is also included (5).
Advantages: This method is easy and affordable. A flexible measuring tape and calculator are all you need. These tools can be used at home and are portable.
Disadvantages: Body circumference equations may not be accurate for all people due to differences in body shape and fat distribution.
Availability: A flexible measuring tape is easily available and very affordable.
Accuracy: The accuracy can vary widely based on your similarity to the people used to develop the equations. The error rate can be as low as 2.5–4.5% body fat, but it can also be much higher (3).
Instructional video: Here is a video showing examples of girth measurements.
Explanation:
Body composition is a method of breaking down the body into its core components: fat, protein, minerals, and body water. It describes your weight more accurately and provides a better glimpse into your overall health than traditional methods. Body composition analysis can accurately show changes in fat mass, muscle mass, and body fat percentage.
