Additionally, Natural Metabolism Boost ultrasound US device can be used to differentiate Allergy-friendly cooking tips from visceral fat, and has been applied for skinfold measurements as well 9.
Fst et al. However, historically, Sbucutaneous correlations between TBF and skinfolds were usually arrived at after caliper use 8. Consequently, we need Subcutqneous as tiesue whether ultrasound US and caliper measurements of subcutaneous fat are equally accurate. Although several studies have already been carried out on this topic, their results are inconsistent, which is not surprising considering the innumerable skinfold equations and varying statistical methods applied 1112 In contrast to previous approaches, clarification is needed as to whether if measurement devices are interchangeable.
The aims of the study were: a Intrarater and interrater reliability of US and caliper, b SFT comparison between both methods and in 4 cases with MRI of various body types.
We expected a difference between methods depending on the thickness of subcutaneous fat. All participants received an information letter and signed written informed consent forms. Two experienced sport scientists carried out the examinations.
This study included 54 participants aged To ensure a heterogeneous study population, we aimed to enroll participants with various body types. Study participants were excluded if they were enrolled in other studies, had any infectious disease, experienced a recent pregnancy or had any metal in their body or any type of cardiac devices.
The participants were examined twice within a week. The pre-examination included a medical history, sports activity questionnaire, and weight and height measurements. We then carried out systematic body mapping, and two consecutive caliper and US measurements were taken to evaluate intrarater reliability.
Consecutively, a bioelectrical impedance analysis BIA was performed. To assess interrater reliability, the second observer repeated the process within a week median: 2 days. Both measurements were carried out in the morning. During the trial, the participants were instructed not to change their behavior in diet or training and were scheduled independently and randomly by raters.
The participants played an exclusively passive role in the measurements, thus there was no learning effect or habituation to the study setting. After the measuring procedure, field 2, 15, 36 and 39 were marked so that the MRI could be done immediately afterwards. MRI measurements were only scheduled for 50 participants.
Sample size was defined by a case number calculation G-Power Ver. To detect a difference of 10 percent between SFT measurements at 0. We recruited and enrolled 54 participants to ensure sensitivity. The emphasis of our study is to measure SFT applying a systematic mapping method.
Therefore, only the right side of the body was divided into 56 rectangles. The head, hand, foot, and genital areas were omitted. Each rectangle was numbered 1—56, Fig. The upper and lower medial length-marking points were first set for each body part.
The distance in between was measured, and divided by the number of fields defined and marked along the virtual line. The width of a rectangle was determined by further landmarks or delimited by adjacent fields. For example, fields 47—49 on the posterior thigh have their medial origin at their anatomically defined location and adjoin fields 35—37 on the anterior thigh Fig.
The center of each field represented the spot of interest. An accurate description of the landmarks is found in Supplementary Table S1. To avoid a labeling error, a preliminary examination was carried out. The thickness of skinfolds was measured with a Holtain caliper Holtain, Dyfed, UK, range 0—40 mm with 0.
After mapping, the measurement started with the subject in supine position. The caliper was applied at right angles to the pinch. Within each field, two measurements formed an average value, which was divided by two due to the skinfold double layer. To avoid discomfort and to leave the measurement accuracy unaffected in the presence of glandular tissue, no caliper measurements were taken on fields 12 and 17 in women.
Once all the anterior parts had been measured, the subject moved into a prone position. The US images were generated by a B-Mode device GE Healthcare GmbH, LOGIQ e, Vivid series with linear transducers of 12 MHz in longitudinal position to measure SFT depending on the approximate tissue depth.
However, an optimum of brightness, gain and dynamic range was individually adjusted by the observers to achieve the best possible tissue delimitability.
The measurement area should be aligned to the center of the image. When boundaries were clearly distinguishable, the US probe was slowly lifted off until the pressure was low enough due to SFT viscoelasticity. When the area of interest was clearly definable, the image was captured. In abdominal areas, the image was captured when the subject stopped breathing at mid-tidal expiration.
As the MRI or the caliper cannot clearly differentiate fibrous structures or the skin, they were not excluded from US either. The distance between skin and muscle tissue was measured to 0. Since the caliper involves the skin, it was not excluded from US either. In 50 participants MRI measurements of SFT at 4 sites were performed fields: 2, 15, 36, 39; Philips Achieva 1.
In 34 of these participants, additional measurements of skinfolds were conducted to visualize the anatomy of field This was done in order to clarify the marked differences between US and Caliper in field 15, which revealed the highest incongruence A whole body coil was selected.
The cross-sectional image was displayed after fields were marked with a specific pellet Fig. As the Caliper is incompatible with MRI, the test person held the marked skinfold in field 15 with their own hands after receiving detailed instructions.
A sagittal slice was obtained while the subject was in supine position. Although we were aware that the skinfold pressure would vary individually, this idea was primarily used to elucidate the difference between US and Caliper. Only for descriptive purposes, TBF was determined via Body Comp Software 8.
de using the segmental BIA Anniversary Sport Edition Akern srl, Florence, Italy. SFT and TBF measurements were carried out consecutively. All statistical evaluations are done with the programs SPSS 23 SPSS Inc. Arithmetic mean x̅standard deviation SDstandard deviation of difference s D and mean difference d̅ are calculated for descriptive statistics.
The two-way random effects model was used to calculate the ICC of interrater reliability and two-way mixed effects for intrarater reliability To visualize test differences, a Bland—Altman plot illustrated the results We evaluated 53 participants for caliper and 54 for US measurements applying our mapping method.
One had to be excluded for caliper as his skinfold measurement was not applicable during the measuring process. There were no systematic errors in these measurements. Bland—Altman-Plot a : intrarater caliper reliability mean

Equations are used to predict body fat percentage based on these measurements. It is inexpensive and convenient, but accuracy depends on the skill and training of the measurer. At least three measurements are needed from different body parts. The calipers have a limited range and therefore may not accurately measure persons with obesity or those whose skinfold thickness exceeds the width of the caliper. 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. Readings may also not be as accurate in individuals with a BMI of 35 or higher. Individuals are weighed on dry land and then again while submerged in a water tank. This method is accurate but costly and typically only used in a research setting. It can cause discomfort as individuals must completely submerge under water including the head, and then exhale completely before obtaining the reading. This method uses a similar principle to underwater weighing but can be done in the air instead of in water. It is expensive but accurate, quick, and comfortable for those who prefer not to be submerged 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. DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density. It cannot distinguish between subcutaneous and visceral fat, cannot be used in persons sensitive to radiation e. 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. However, CT and MRI scans are typically used only in research settings because the equipment is extremely expensive and cannot be moved. CT scans cannot be used with pregnant women or children, due to exposure to ionizing radiation, and certain MRI and CT scanners may not be able to accommodate individuals with a BMI of 35 or higher. Some studies suggest that the connection between body mass index and premature death follows a U-shaped curve. The problem is that most of these studies included smokers and individuals with early, but undetected, chronic and fatal diseases. Cigarette smokers as a group weigh less than nonsmokers, in part because smoking deadens the appetite. Potentially deadly chronic diseases such as cancer, emphysema, kidney failure, and heart failure can cause weight loss even before they cause symptoms and have been diagnosed. Instead, low weight is often the result of illnesses or habits that may be fatal. Many epidemiologic studies confirm that increasing weight is associated with increasing disease risk. The American Cancer Society fielded two large long-term Cancer Prevention Studies that included more than one million adults who were followed for at least 12 years. Both studies showed a clear pattern of increasing mortality with increasing weight. According to the current Dietary Guidelines for Americans a body mass index below But some people live long, healthy lives with a low body mass index.

Role of Body Fat We may not appreciate body fat, especially when it accumulates in specific areas like our bellies or thighs. Types of Body Fat Fat tissue comes in white, brown, beige, and even pink. Types Brown fat — Infants carry the most brown fat, which keeps them warm. It is stimulated by cold temperatures to generate heat. The amount of brown fat does not change with increased calorie intake, and those who have overweight or obesity tend to carry less brown fat than lean persons. White fat — These large round cells are the most abundant type and are designed for fat storage, accumulating in the belly, thighs, and hips. They secrete more than 50 types of hormones, enzymes, and growth factors including leptin and adiponectin, which helps the liver and muscles respond better to insulin a blood sugar regulator. But if there are excessive white cells, these hormones are disrupted and can cause the opposite effect of insulin resistance and chronic inflammation. Beige fat — This type of white fat can be converted to perform similar traits as brown fat, such as being able to generate heat with exposure to cold temperatures or during exercise. Pink fat — This type of white fat is converted to pink during pregnancy and lactation, producing and secreting breast milk. Essential fat — This type may be made up of brown, white, or beige fat and is vital for the body to function normally. It is found in most organs, muscles, and the central nervous system including the brain. It helps to regulate hormones like estrogen, insulin, cortisol, and leptin; control body temperature; and assist in the absorption of vitamins and minerals. Aerobic activity is a recommended way to burn calories and includes walking, running, cycling, swimming, and other movement-based activities that increase the heart rate. Many people who are increasing their activity to lose subcutaneous fat also participate in strength training like lifting weights. This type of activity increases lean muscle which can boost your metabolism and help burn calories. There are a number of positive reasons that your body has subcutaneous fat, but having an excess can be bad for your health. Spend some time with your doctor to determine the proper amount of fat for you and — if you are not at your ideal level — to help put together a diet and activity plan for optimum health.

Subcutaneous fat tissue -
The subcutaneous layer consists mainly of fat. The fat forms a layer that insulates the body from cold and helps absorb shock and damage to the internal organs.
It also provides structural support for the skin. The body stores fat in the subcutaneous layer. Other components include collagen-rich connective tissue and a network of blood vessels and nerves. In other areas, such as the eyelids, the subcutaneous layer has no fat and may be as thin as 1 millimeter.
The crucial functions of the subcutaneous layer are due to the significant amount of fat it holds. These functions include:.
The blood vessels in the hypodermis dilate to cool the body down. When blood vessels dilate, they open up or enlarge, allowing more blood to flow into the area. The blood flows away from warmer areas of the body toward cooler regions. The heat radiates away from the body into the environment and cools the body down.
Besides insulation, the large proportion of fat in the subcutaneous layer also helps with shock absorption. The subcutaneous layer connects the skin with the fibrous tissue of the bones and muscles underneath.
The subcutaneous layer also produces hormones such as leptin. These hormones send a signal to the body to tell it that it has eaten enough, which helps regulate energy. Subcutaneous fat is the fat located in the subcutaneous layer. Adipocytes, or fat cells, hold the fat in specialized connective tissue called adipose tissue.
This fat is called visceral fat. A subcutaneous injection is an effective method of injecting medications. People use injection sites on the outer surface of the upper arm, top of the thigh, and the area of the abdomen surrounding the belly button to administer subcutaneous injections.
Anyone administering a subcutaneous injection must avoid placing the needle into the muscle. Injecting into the subcutaneous layer allows the body to absorb the drug slowly. The slow absorption rate is because compared with muscle, the subcutaneous tissue has far fewer blood vessels.
Any substance injected into this layer is absorbed far slower than if someone injected it into the muscle. Any medicine injected using the subcutaneous route must be a water-soluble, non-irritant drug administered in small quantities of up to 2 milliliters. Subcutaneous injections have some drawbacks.
People may experience abscesses, which are areas of pus under the skin. Anyone who needs frequent injections may experience an accumulation of fat under the skin called lipohypertrophy.
People can avoid this by varying the injection site, as it typically happens when an individual has multiple injections in the same area. Anything that penetrates the upper layers of skin can damage the subcutaneous layer. As the subcutaneous layer is the deepest skin layer, conditions that damage it can sometimes be severe.
Burns have different classifications according to how deeply they penetrate. The two classifications of burns that affect the subcutaneous layer are third degree and fourth degree burns. Third degree burns destroy the entire epidermis and dermis and may impact the subcutaneous tissue. These burn sites may appear either white or blackened.
Fourth degree burns enter the subcutaneous layer and may go even deeper. These types of burns may involve the bones and muscles. Since this burn type destroys all the nerve endings in the subcutaneous layer, a person does not have feeling at the burn site.
An abscess is a pocket of pus that can form anywhere in the body, often in the subcutaneous layer of skin. Pus forms from fluid, WBCs, debris, and dead bacteria. The surrounding area becomes swollen, inflamed, and painful.
If someone has prolonged pressure on their skin due to lying in bed or using a wheelchair, they could develop a pressure ulcer. These skin injuries, also called pressure sores or bedsores, can affect the skin and potentially the subcutaneous layer if they are severe.
People can develop a tumor , such as a sarcoma , in the subcutaneous layer if there is an uncontrolled growth of cells.
Unlike many other types of tumors, people can easily see these masses, and doctors can examine them to see how firm and mobile they are, which helps with diagnosis. These tumors can be benign or malignant.
Panniculitis is an umbrella term for a variety of diseases concerning subcutaneous tissue. The signs of panniculitis include inflammation in the subcutaneous layer and possible scarring of the subcutaneous tissue.
This condition is most often associated with autoimmune disorders. It can also be caused by infection and trauma. The subcutaneous layer is located underneath the dermis and is one of the three layers of the skin.
It is the deepest skin layer, composed of fat cells, collagen, blood vessels, and nerves. The subcutaneous layer has many functions, including insulation, thermoregulation, shock absorption, structural support, and energy storage.
Everybody is born with subcutaneous fat. Aside from genetics, people typically have greater amounts of subcutaneous fat if they:. The top layer of your skin is the epidermis. The middle layer is the dermis. Subcutaneous fat is the deepest layer. Subcutaneous fat is an important part of your body, but if your body is storing too much of it, you may be at a higher risk for health problems including:.
One way of determining if you are overweight is by measuring your body mass index BMI , which provides the ratio of your weight to your height:. Another way to determine whether you have excess fat is to measure your waist size. The two most frequently recommended methods for shedding excess subcutaneous fat are diet and physical activity.
The basic principle of losing subcutaneous fat via diet is to consume fewer calories than you burn. There are a number of dietary changes that help improve the types of food and drink you consume.
The American Heart Association and the American College of Cardiology recommend a healthful diet that is high in fruits, vegetables, fiber, whole grains and nuts.
It should also contain lean proteins soy, fish, or poultry and should be low in added sugars, salt, red meat, and saturated fats. One way your body stores energy is by building up subcutaneous fat.
Aerobic activity is a recommended way to burn calories and includes walking, running, cycling, swimming, and other movement-based activities that increase the heart rate. Many people who are increasing their activity to lose subcutaneous fat also participate in strength training like lifting weights.
This type of activity increases lean muscle which can boost your metabolism and help burn calories. There are a number of positive reasons that your body has subcutaneous fat, but having an excess can be bad for your health.
