Underwater weighing testing

Hydrostatic body composition testing -

As scientists began to dive deep literally into the different tissues, organs, and fluids that keep our bodies in motion, methods of measurement were derived in an attempt to gather information accurately and consistently.

The early mathematician, Archimedes, posed a key theory in physics that provided the foundation for body composition analysis. In the case of body composition testing, lean mass is denser than water, while fat mass is less dense than water. Therefore, a person with more fat will weigh less under water than someone with more muscle.

Testing requires a participant to be lowered underwater with all air expelled from their lungs to gather measurements of water displacement. The process is usually repeated three times, with calculations from each measurement averaged to determine total fat mass, lean mass and body fat percentage.

The principle of hydrostatic weighing is technically accurate — that is, if all methods and calculations are correctly implemented, an accurate read of body fat and lean mass can be determined. However, several variables can be sources of error, such as the subject not expelling all of the air out of their lungs, or if the individual completing the test is not accurate with calculations.

Bone density can also skew actual results. As society progresses, so does science. Discoveries in technology are constantly reinventing traditional methods of testing protocol and measurements across almost all industries.

The same advent of technological breakthroughs is also experienced in health. Over the past half-century, other forms of body composition testing were developed that used a different approach based on more cutting edge body imaging technology.

Most notably, X-ray imaging devices opened a new door to body composition analysis. This method differs from hydrostatic testing in a few major ways.

This is due to the advanced X-ray technology that leave little guesswork and no extra calculations to provide accurate data. Unlike hydrostatic weighing, there is no need to expel air, remove clothing or do any type of preparation before a DEXA scan.

Most methods of body composition testing only provide a reading of total body fat and lean mass. Similarly people who have high body fat percentages, but have lost muscle tissue may appear healthier according to BMI because they lost weight.

Many health insurance companies still use BMI today and, in turn, health insurance costs go up because of inaccuracies. Visceral fat is a type of fat locate in your belly between your organs.

There is a high level of correlation with obesity-related diseases such as Type 2 Diabetes and heart disease. In contrast, fat under the skin — subcutaneous fat — is not necessarily harmful to your health.

It is quite possible for individuals who appear thin and have a healthy BMI to carry stores of high-risk visceral fat. In fact, studies have found that waist size measurements are better correlated that BMI with Type 2 Diabetes simply because waist size measurements better account for the presence of visceral fat.

What is Hydrostatic Testing. Your age, sex, and activity level will also affect your percentage of body fat. For example, endurance runners have less body fat than swimmers. But body fat percentage is not the best way to measure your risk for weight-related diseases. Your doctor may also suggest checking your BMI body mass index , your waist size, and your waist-to-hip ratio.

Your waist-to-hip ratio is a comparison of your waist size to your hip size. A higher BMI, waist size, and waist-to-hip ratio means that you are at higher risk for weight-related disease. Author: Healthwise Staff Medical Review: Anne C.

Hydostatic mass consists of all the adipose tissue fat within your body. Lean mass consist of bone, bodily fluid bloodorgans, and skeletal muscle. The BOD POD test provides results of these two categories expressed as percentages of total body mass. Body composition testing may feel uncomfortable for the parties involved. Hydrostatic weighing with measured residual volume composittion a valid compositin Acai berry recipes. Hydrostatic Acai berry recipes or underwater weighing involves sitting Hydrosttatic a Meal replacements for post-game recovery suspended from a Acai berry recipes in Hydrostatic body composition testing tank of warm water. You will be asked to exhale all of the comosition from your lungs while you are totally immersed underwater, during which your weight is measured. This is done several times in order to ensure accuracy. Residual Volume : To increase the accuracy of hydrostatic weighing, a residual volume RV test is also conducted; this test provides an accurate measurement of the amount of air trapped in the respiratory system once you have exhaled as much air as possible. This test is needed only the first time you have the hydrostatic weighing test and is good for 8 years. UNMH Employee:.
