Subcutaneous fat and body composition -

Assessing Body Composition The search for valid methods of measuring body composition that are practical and inexpensive is an ongoing process for exercise scientists and nutritionists.

Standard age-height-weight tables derived from life insurance data often incorrectly indicate individuals to be overweight. Some practical methods of measuring body composition include skinfolds, circumference girth measures, hydrostatic weighing, bioelectrical impedance, and near-infrared interactance.

Other advanced methods discussed in research journals include isotope dilution, neutron activation analysis, magnetic resonance imaging, and dual-energy x-ray absorptiometry.

This error factor may be increased dramatically due to the skill or lack of it of the technician taking the measurements. The following sections will focus on three body fat measurement techniques that are often accessible to fitness professionals: hydrostatic weighing, bioelectrical impedance, and skinfolds.

Hydrostatic Weighing Hydrostatic weighing is a valid, reliable and widely used technique for assessing body composition. It has been labeled the "Gold Standard" or criterion measure of body composition analysis. It is based on Archimedes' principle.

This principle states that an object immersed in a fluid loses an amount of weight equivalent to the weight of the fluid which is displaced by the object's volume.

This principle is applied to estimate the body volume and body density of individuals. Since fat has a lower density than muscle or bone, fatter individuals will have a lower total body density than leaner individuals.

As the person is being submerged, the air in the lungs must be exhaled completely. The air remaining in the small pockets of the lungs following a maximal expiration is referred to as the residual lung volume.

The residual lung volume may be determined using a number of laboratory techniques or it is often estimated using age, height, and gender-specific equations. Once your body weight, the underwater weight, and the residual lung volume are known, total body density may be calculated.

From the total body density, the percent body fat can be estimated using the appropriate age-gender equation. One limitation of hydrostatic weighing is that it is based on the two- component model fat and fat-free mass which assumes when calculating total body density that the relative amounts and densities of bone, muscle, and water comprising the fat-free mass are essentially the same for all individuals, regardless of age, gender, race or fitness level.

It is now known that this is not the case. For instance, the fat-free body density of young Black men is greater than that of white men.

Because of this, the lean body mass is overestimated and the body fat is underestimated for many Blacks. Also, after age 45 to 50, substantial changes in bone density, especially in women, invalidate the use of an assumed constant value for fat-free body density when converting total body density to percentage of body fat.

This is why age and gender specific equations need to be used for estimating body fat. As researchers learn more about age-related changes in bone mineral, hydrostatic weighing will eventually provide a more accurate prediction of body fat for older men and women.

Bioelectrical impedance analysis BIA is based on the fact that the body contains intracellular and extracellular fluids capable of electrical conduction.

A non-detectable, safe, low-level current flows through these intracellular and extracellular fluids. Since your fat-free body weight contains much of your body's water and electrolytes, it is a better conductor of the electrical current than the fat, which contains very little water.

So this technique is essentially an index of total body water, from which fat-free mass is estimated. The popularity of the BIA method has grown significantly over the last few years because it is painless, quick, and easy to administer the test. To take the test, you lie on a testing table or floor and electrodes are attached to your hands and feet.

You do not feel a thing as the current passes through your body. Average time for administering this test is about 10 minutes.

No eating or drinking within 4 hours of the test 2. No exercise within 12 hours of the test 3. Urinate within 30 minutes of the test 4. No alcohol consumption within 48 hours of the test 5. There is a tendency for BIA to overestimate percent body fat in very lean clients and underestimate body fat in obese clients.

All in all, if the guidelines for testing are followed, the BIA method is a satisfactory method for assessing body composition of most people. Skinfold Method The skinfold method of measuring body fat is a practical, economical, and administratively feasible field technique for body composition analysis.

It involves measuring the skinfold subcutaneous fat thickness at specific sites of the body. Most equations use the sum of at least three skinfolds to estimate body density from which body fat may be calculated.

Skinfold measurement does not require expensive equipment and it can be routinely incorporated into many health promotion settings. Skinfold technicians can be trained rather easily, but must practice on at least clients before the skinfold technique is mastered.

When using the skinfold method, it is assumed that the distribution of subcutaneous fat and internal fat is similar for all individuals. This assumption is not fully supported. It is now known that older subjects of the same body density and gender have proportionately less subcutaneous fat than their younger counterparts.

There is considerable biological variation in the distribution of subcutaneous, intermuscular, intramuscular, and internal organ fat due to age, gender, and degree of fatness Heyward, Accuracy of Skinfold Measurements The accuracy of the skinfold method is dependent on the technician's skill as well as the type of caliper and the skinfold prediction equation used.

Reasonably priced plastic calipers have a less precise measuring scale, and often provide variable pressure and a smaller range of measurement.

Despite this, a number of researchers have reported only small differences between skinfolds measured with high quality calipers and plastic calipers for highly skilled technicians refer to Guide to Skinfold Caliper for more information on where to purchase calipers. However, plastic calipers are not recommended for use by untrained technicians.

Practical methods of assessing body composition such as skinfolds, bioelectrical impedance analysis BIAand hydrostatic weighing are based on the two-component fat and fat-free mass model of body composition.

Standards of Body Fatnessary Our bodies require essential fat because it serves as an important metabolic fuel for energy production and other normal bodily functions. Body fat percentages for optimal fitness and for athletes tend to be lower than optimal health values because excess fat may hinder physical performance and activity.

When prescribing ideal body fat for a client, you should use a range of values rather than a single value to account for individual differences. As a result of these changes, men and women who weigh the same at age 60 as they did at age 20 may actually have double the amount of body fat unless they have been physically active throughout their life Wilmore et al.

Insulin-stimulated glucose disposal Rd ranged from 3. kg-1 FFM. In addition to manifesting the strongest simple correlation with insulin sensitivity, in stepwise multiple regression, subcutaneous abdominal fat retained significance after adjusting for visceral fat, while the converse was not found. Muscle attenuation contributed independent significance to multiple regression models of body composition and insulin sensitivity, and in analysis of obese subjects, muscle attenuation was the strongest single correlate of insulin resistance. In summary, as a component of central adiposity, subcutaneous abdominal fat has as strong an association with insulin resistance as visceral fat, and altered muscle composition, suggestive of increased fat content, is an important independent marker of insulin resistance in obesity. This type of fat is considered more dangerous than subcutaneous fat in terms of increased health risks from having too much. Both types of body fat are linked to a higher risk of cardiometabolic disease. Still, visceral fat is shown by research to be more associated with metabolic risk factors, insulin resistance, inflammation, and overall mortality. You can lose excess visceral fat the same way you'd lose subcutaneous fat: with a healthy diet, exercise, and controlled stress levels. Subcutaneous fat is a type of fat that the body requires for several reasons, including temperature regulation and hormone production. However, too much subcutaneous fat, especially on the abdomen , can lead to health risks. Keeping your body fat levels at a healthy range through diet and exercise is key.
