What is the density of the body?

body density is the proportion of body fat present in the human body compared to its overall weight. Also known as body fat composition , it is used as a tool for measuring how much greasy tissue, essential and excess, exists in the body. Knowledge of the body density is a critical piece of data in the Nutrition and Fitness Plan. The most common and easiest way is known as the body weight index (BMI), which includes the use of body weight and height for generating a number that can be compared with the basic graph. Individuals can use their BMI to determine whether their body density is at a healthy level .. While a reasonable tool for estimating to most types of body, BMI loses accuracy between strongly muscular individuals, because muscles weigh more than fat and distort results. For example, bodybuilders often show that they are obese on body weight index due to their high weight to height, despite the relative lack of body fat.

other, more scientific methods for estimating body density include skin measurement, analysis of bioelectric impedance (BIA), interactivity of close infraredness, X -ray absorption with dual energy (DXA) and weighing underwater. Skinfold, close to infrared interactions and BIA techniques are less expensive than the newer DXA method, but are less accurate and have more restrictions.

The

Skinfold analysis is the oldest and least advanced method that includes the use of stirrups to measure the amount of excess tissue untreated on the body. BIA uses different lair of bones, muscle and fat, which provide the level of body density by running electric current between two wires located on different parts of the body and measurement of resistance. The interaction of close infraredness involves shooting almost infrared beam of light through the muscles of the upper arm. Light is absorbed by oily tissue, but reflects back from the muscle. Therefore the amount of light that leaves the arm is a good indicator of how much fatis present.

DXA is currently considered the main technique for estimating body density. Two different types of X-ray machines-one, which detects all types of tissues and one that detects only fat-to see the body and suggests to what extent the fat is present. DXA is a relatively involved process compared to other methods. It is generally used in conjunction with a process known as weighing underwater, which uses the principles of buoyancy and the known weight difference between the same amount of muscle and fat to ensure reliable results.
