Skinfopd is because, even though we mesurement the measurdment prediction Skinfold measurement vs, our measurement methodology fundamentally differs from skinfolds.
Ultrasound measures of subcutaneous fat, by their very nature, are far more consistent, accurate and reliable than skinfold measures. We have demonstrated the accuracy and reliability of this methodology with only a brief period of training.
The remainder of this article lists the inherent error potentials of skinfold measurements and describes each one with comparative aspects of the MuscleSound protocol. But this is not always possible. When this occurs, caliper placement is an issue for even the most experienced tester.
Typically they will just use their best judgment and hope they can replicate the caliper placement on subsequent measures. Clearly this is not the best case for reliability!
As illustrated by the graphic below, the Ultrasound probe is placed firmly and comfortably on the surface of the site to be measured and we take a direct, linear measure of the subcutaneous fat layer. As the skinfold calipers are placed around the fold, the fat layers compress in an amount proportional to the force exerted by the caliper.
However, this force is not the same for all makes of caliper. For example force differences of between g and g have been reported for the five most popular models of caliper.
Also, if calipers are not regularly calibrated, there is a danger of errors occurring between the same caliper models. The length of time caliper jaws are kept on the fold will also impact how much the fat layer is compressed.
Skinfold Best Practice is 4 seconds. A shorter or longer time than this will result in a correspondingly greater or lesser reading on the caliper dial. When a fold is hard to lift and you are trying to get as close to parallel sides as possible, it is necessary to squeeze really hard!
For some individuals lifting a difficult fold is too painful for them to bear! In contrast, with MuscleSound there are no compression, pain or ticklishness issues.
As illustrated by the graphic above, the Ultrasound wand is placed firmly and comfortably on the surface of the site to be measured and we take a direct, linear measure of the subcutaneous fat layer. Sweat, body lotions, sunscreen and other body creams make it hard, and sometimes impossible to lift a fold, and hold it for the required 4 seconds.
In contrast MuscleSound is not affected by sweat, or any kind of body cream acting on the skin. Still need help? Contact Us Contact Us.

Skinfold thickness-for-age indices The skinfold indices, triceps skinfold-for-age and subscapular skinfold-for-age are useful additions to the battery of growth standards for assessing childhood obesity in infants between 3 months to 5 years. Strengths and limitations. An overview of skinfold thickness methods is outlined in Table 5. The majority of national reference data available are for skinfolds at the triceps and subscapular locations. The triceps skinfold varies considerably by sex and can reflect changes in the underlying triceps muscle rather than an actual change in body fatness. Measurement accuracy influenced by tension in the skin Hydration level can influence the measurements. Dehydration reduces the skinfold size. Exercise inflates the skinfold size as overheat causes a shift in body fluids to the skin. Oedema and dermatitis increase the skinfold size. Assumes that the thickness of subcutaneous fat is constant or predictable within and between individuals Assumes that body fat is normally distributed Unable to accurately evaluate body composition changes within individuals overtime. Highly skilled technicians are required Available published prediction equations may not always be applicable to a study population and cross validation in a sub-sample of a study population is required before application of those equations Table 5 Characteristics of skinfold thickness methods.

Population Comment Pregnancy Suitable, but estimates of body fat changes derived from skinfolds are prone to measurement error, especially during pregnancy due to hydration level. Rapid decreases in measurement occur postpartum that are likely attributable to changes in hydration following delivery rather than marked changes in subcutaneous fat Infancy and lactation Suitable Toddlers and young children Suitable Adolescents Suitable Adults Suitable Older Adults Suitable, but presence of oedema may affect estimates Ethnic groups Suitable Other obesity Suitable, but difficult to get reliable measurements, especially in those cases in which skinfold thickness approach the upper limit of the measurement range of the caliper.

For legal reasons, it is wise to have another person present, and to have females testers for female participants. The right side measurement is standard, though in some situations you may need to test someone on the left side. If so, you must record this and endeavor to always test on the same side for that person. Reasons for testing on the left side may include injuries, amputation, deformities, or other medical conditions. We have over fitness tests listed, so it's not easy to choose the best one to use.

The impedance is believed to be in proportion to the height and inversely proportional to the cross-sectional area of each compartment. The resistance, which is known as impendence, was measured 8. Total body fat percentage, total body water, muscle mass, mineral mass and visceral fat was recorded. Statistical analysis was carried out in SPSS software v. Analysis was reported based on the STROBE guidelines 9. Descriptive statistics was used to represent the data. The bias and limits of agreement mean difference ±3SD were calculated by using mean and standard deviations of the difference between body fat percentages obtained from SFT and BIA Linear regression was used to study the association between body fat percentages obtained and its contributing factor anthropometric measurements and impedance values. In total female students participated in the study. Mean height and weight of the participants was Their mean BMI was Table 1 describes details of all parameters measured for assessment of body composition. Mean BMI Visceral fat percentage was found to be within the healthy range. Figure 1: Distribution of Participants Across BMI Categories. Click here to view Figure. It is illustrated in the figure 1. However, the body fat percentage obtained by both these methods differ. Figure 2: Correlation of BIA and SFT Techniques for Assessment of Body Fat Percentage. BIA overestimates the body fat percentage with limits of agreement Figure 3: Bland-Altman Plot for Comparison of BIA and SFT Techniques for Assessment of Body Fat Percentage. Currently adiposity is used as a marker to define the obesity rather than relation of body weight to body height which is BMI. Our study has attempted to explore the comparison between two most commonly used methods in clinical practice and research for assessment of adiposity. In our study, mean BMI was observed to be within the normal category but WHR is at borderline of cut-offs recommended by WHO 6 which describes the trend of central obesity. Similarly, body fat percentage is also higher than the cut-offs for women Alvero-Cruz et al found that body fat percentage measured by BIA strongly correlated with readings by different anthropometric methods Results from our study also have depicted a linear correlation between both methods studied. However, it is important to note that the results depend on number and sites of skinfolds as well as variations in the distribution of subcutaneous fat 14, In most settings, SFT, BIA and other 2 compartment models are the only techniques available for body composition measurements. The Bland-Altman analysis was done to test the proportional bias and limits of agreement. Limits of agreement estimates likely differences between individual results measured by two methods. Our observations have showed that BIA overestimates the body fat percentage compared with body fat percentage derived by SFT method. Similar findings have been reported by studies done in United States of America, Colombia and Indonesia 16,17, Study done in Indonesian girls have reported that SFT method is one of the practical approaches to assess body composition They further also have discussed that change in body water and electrolyte influences BIA measurements and this may lead to errors in body fay percentage evaluation. According to study done on Indian population by Bhat et al a commercial BIA machine overestimated body fat percentage compared with multiple skinfolds and Durnin-Wormesley equation method 5. They have also suggested that SFT measurements by Durnin and Wormesley equation may be more appropriate for Indian population. Findings from our study have shown contradictory results with the studies done on Indian population by Chahar et al and Devi et al 4, Both researchers have independently suggested that BIA underestimates body fat percentage when compared with SFT method. Kuriyan R et al have stated that SFT and BIA both underestimate the body fat percentage when compared to the 4-compartment model to validate Both methods cannot be alternative to each other. Each method has its own limitations and applicability, but both are uncomplicated, practical, inexpensive and easy to administer particularly in epidemiological studies.

A weak electrical current is run through the body to identify the speed of conductivity based on total water in the body which correlates to body fat percentage. Fat has a lower water content than muscle or connective tissues, therefore more fat will slow down, or impede, the electrical current.
With more lean mass the current will progress through the body in a quicker fashion. PROS This modality is very easy to use and therefore limited tester expertise is required. The assessment can be performed in a very rapid fashion for all populations and both genders.
The hand-held modalities commonly used in personal training make the assessment protocol virtually fool-proof. It can be a fairly reliable method for examining improvements in body composition if all conditions are equal.
CONS Bioelectrical impedance protocol was developed in the clinical setting, and it differs greatly from the protocol implemented within the personal training setting. Assessment discrepancies though exist between the two. In the clinical setting, which correlates to a validity consistent with skinfold, electrodes are placed on the thin skin on the top of the hand and foot, and the participant is expected to lie on a non-conducted surface and in a completely resting state.
With the hand-held assessment commonly used in personal training, the skin thickness of the palms can have a significant effect on validity of the test, and the participant may not be aware of guidelines necessary for the test to be valid.
The test results can be negatively affected by hydration level, ambient and skin temperatures, skin permeability location of electrodes , equation used, exercise or alcohol consumption within 24 hours prior to the test, the use of diuretics or specific medications, female menstruation, and the need to void the bowel and bladder before the assessment.
