Body fat analysis method -

Example analysis from a DXA scan PDF. Although body fat endures a negative reputation, fats and lipids play critical roles in the overall functioning of the body, such as in digestion and energy metabolism. Fat is the body's energy provider and energy reserve, which helps the body maintain a constant temperature.

Fats and lipids are also involved in the production and regulation of some hormones such as, steroid hormones. These are essential in regulating sexuality, reproduction, and development of the human sex organs, as well as in regulating the water balance in the body.

Fats and lipids also have important structural roles in maintaining nerve impulse transmission, memory storage, and tissue structure. Lipids are the major component of cell membranes. Fat serve as an energy reserve for the body, particularly as exercise progresses past 20 minutes. From a performance stand point, excess body fat lowers your work to weight ratio, This means that a heavier person would consume more energy per minute of work resulting in a lower energy economy during activity.

In addition, excess body fat can lead to additional loads placed on joint during weight bearing activities such as running, causing joint distress. Healthy or athletic body fat percentages typically allow for more optimal performances, due to the improved economy and reduced injuries.

The immune system is often impaired when body fat stores are too low. A reduced ability to fight infections means more interruptions in training and more chance of being sick on race day.

For female athletes, there are some very immediate consequences of a low body fat level, including a fall in circulating oestrogen levels.

This in turn can lead to a loss of bone mass, causing problems for women in later life through an increased risk of bone fracture. Assessing body fat can be done using the following methodologies: Hydrostatic weighing, skinfold assessment and bio-electrical impedance.

Of these methods, one that is both accurate and practical is skinfold measurement. The measurements are taken with calipers, which gauge the skinfold thickness in millimeters of areas where fat typically accumulates i. Once the measurements are recorded, the numbers are inserted into an equation that calculates a body fat percentage and alternatively body lean mass.

Skinfold is a preferred method of body fat measurement for non-clinical settings because it is easy to administer with proven accuracy and is not obtrusive with regards to the patient.

It also provides much more data than just the final composition measurement - it also yields the thickness of many sites, which can be used as bases of comparison with future results.

For example, an abdominal skinfold improvement from 35mm to 24mm would show a significant improvement in that site even if the overall body fat percentage may have only reduced minimally.

BMI is often mistaken as measurable guide to body fat. However, BMI is simply a weight to height ratio.

Here is a brief overview of some of the most popular methods for measuring body fat-from basic body measurements to high-tech body scans-along with their strengths and limitations. Adapted from 1. Like the waist circumference, the waist-to-hip ratio WHR is also used to measure abdominal obesity.

Equations are used to predict body fat percentage based on these measurements. BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance.

The current faces more resistance passing through body fat than it does passing through lean body mass and water. Equations are used to estimate body fat percentage and fat-free mass. 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.

BMI is often mistaken as measurable guide to body fat. However, BMI is simply a weight to height ratio. It is a tool for indicating weight status in adults and general health in large populations.

BMI correlates mildly with body fat but when used in conjunction with a body fat measurement gives a very accurate presentation of your current weight status. With that being said, an elevated BMI above 30 significantly increases your risk of developing long-term and disabling conditions such as hypertension, diabetes mellitus, gallstones, stroke, osteoarthritis, and some forms of cancer.

For adults over 20 years old, BMI typically falls into one of the above categories see table above. UC Davis Health School of Medicine Betty Irene Moore School of Nursing News Careers Giving.

DXA body composition analysis	Also, we love the quick assessment time and ability to see the body composition output in 3D form. ROI: Very accurate, but much better for an academic or medical setting. Above Average. These measurements are taken manually at the abdomen and neck for men and women's neck, waist, and hips. com and start your free day trial today. User Experience: Let's face it. Nonetheless, unlike calipers, there's no pinching involved.
Measuring Obesity	A DXA or DEXA scan is the most accurate and advanced form of body composition analysis available. A person's body weight is comprised of multiple factors including but not limited to body fat, muscle, bone density, and water content. Bioelectrical impedance scales range from the simple a normal scale with electrodes under each foot to the complex a scale that has handholds with additional electrodes. Many can also tell you your muscle mass. There are many specific techniques used for measuring body fat. For most body types, 3D mapping comes within two percent of the accuracy of the DEXA method.
The 6 Great Ways to Measure Body Fat Percentage	Although we typically avoid language like this, specificity is key when reporting on research participants and clinical findings. Although the test takes a measurement from each main area of the body including the upper body , midsection and lower body , a participant that holds greater amounts of fat outside of the measured areas might end up with a lower reading. To get a more accurate estimation, measure the circumference of the neck and waist. The least expensive and most popular tests include:. On a related note, studies have found that excess body fat, particularly abdominal fat, disrupts the normal balance and function of some of these hormones.
