This technique weighs you while submerged under water after exhaling as much air as possible from your lungs. Below are body fat ranges for males and females, according to the American College of Sports Medicine :. This article takes a look at the science behind targeted fat loss, and checks if you can slim down specific areas of your body. Body volume measurement technique

Body volume measurement technique -

They made much of its limitations. Unfortunately, crystalloid tracers don't distribute homogeneously into the various compartments of the ECF. Also, mannitol drags the water out of the intracellular compartment, because it is osmotically active. This changes the volume which is being measured. The injection of Evans Blue dye is used, because this dye binds to albumin.

This has also been used to investigate the fate of albumin, and the permeability of the blood-brain barrier. There is a constant leak of albumin out of the circulation, and so the tracer concentration must be measured on a logarithmic curve and then extrapolated to a "zero time" when the virtual volume of distribution is measured.

With albumin-bound tracer, you can arrive at the plasma volume. If you also know the haematocrit, you can calculate the blood volume as it only consists of cells and plasma This means there is no need to measure the volume of the red cells. The problem is that the venous haematocrit is generally higher as the result of the Hamburger effect.

Red cells in vein are bloated with the products of carbon dioxide transport, which is osmotically active, and causes them to swell. Additionally, in capillaries, axial streaming results in the separation of red cells and plasma, which means that the haematocrit of capillary blood is about 0.

Lastly, red cells in the measuring tube are trapped together with some plasma, and that plasma goes unmeasured.

Hence, haematocrit is overestimated. They are restricted to the vascular volume. Thus, haematocrit can be omitted from this calculation. Bhave, Gautam, and Eric G. Individuals are weighed in air and while submerged in a tank. Fat is more buoyant less dense than water, so someone with high body fat will have a lower body density than someone with low body fat.

This method is typically only used in a research setting. This method uses a similar principle to underwater weighing but can be done in the air instead of in water. Individuals drink isotope-labeled water and give body fluid samples. Researchers analyze these samples for isotope levels, which are then used to calculate total body water, fat-free body mass, and in turn, body fat mass.

X-ray beams pass through different body tissues at different rates. So DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density. These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass.
