What are potential sources of error for skinfold measurements?
Some potential sources of measurement error when using the skinfold method can mainly be traced back to human error. For example, incorrect pinching technique by to person performing the assessment could result in a larger than actual measurement, if muscle is pinched with the fat.
What can affect skinfold measurements?
Subcutaneous fat, and therefore skinfold thicknesses at the different sites, changes at varying rates with age, weight change, with diseases such as diabetes, and in women during pregnancy, postpartum, and at the menopause.
What is one disadvantage of the skinfold assessment?
A critical disadvantage in the use of skinfolds is that it is limited to the assessment of subcutaneous fat only, and cannot accurately distinguish between abdominal visceral adipose tissue and saturated adipose tissue.
What are the advantages and disadvantages of the skinfold test?
Summary
| Advantages | Disadvantages |
|---|---|
| Quick to execute | High inter-tester variability (i.e. reliability can be poor when the tester does not remain the same) |
| Minimal equipment and subject participation required | Most skinfold calipers have an upper limit of 45–60 mm, limiting their use to moderately overweight subjects |
How accurate is the skin fold test?
The calculations and calipers themselves are very accurate. While there is large room for user error in skin fold measurements, skilled trainers who practice often can obtain up to 98% accuracy.
What is the error range for skin fold measurements?
Skinfold testing equations, like the Jackson-Pollock equation, were developed off of hydrostatic weighing measurements (which themselves are predictions with error). Thus, if hydrostatic weighing can have an error rate of up to 5-6% in individuals, then skinfold testing equations are going to compound that error.
Are skin folds accurate?
While there is large room for user error in skin fold measurements, skilled trainers who practice often can obtain up to 98% accuracy. However, it has been found that skin fold measurements may be less accurate for larger individuals, where it is more difficult to separate muscle and fat by a simple pinch.
What is skin fold measurements?
Skinfold measurement is a technique to estimate how much fat is on the body. It involves using a device called a caliper to lightly pinch the skin and underlying fat in several places. This quick and simple method of estimating body fat requires a high level of skill to get accurate results.
Is the skin fold test reliable?
What is skin fold measurement?
Are body fat callipers accurate?
Availability: Calipers are affordable and easy to purchase online. Accuracy: The skill of the person performing the skinfolds can vary, impacting the accuracy. Measurement errors can range from 3.5–5% body fat (3).
Are there any limitations to the skinfold measurement?
In addition to these limitations in the application of the equations, there are logistical limitations associated with the skinfold measurement process that can result in an inappropriate estimation of the subcutaneous fat thickness and, consequently, total body fat.
How are skinfold measurements used to predict body density?
The skinfold measurements are used in multiple equations to predict percentage body density; this has been reviewed extensively by Brodie et al. [ 81 ]. The equations make several assumptions about the relationships between skinfold thickness and adiposity.
How to take skinfold measurements on the right side?
Take all skinfolds on the right side of the body (for reliability) Ensure that you take the skinfold in a rotational order (circuit) and do not complete consecutive readings at each skinfold site Grasp the skinfold firmly between your thumb and index finger of your left hand.
What do you need to know about the skinfold?
Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Calipers should be calibrated for correct jaw tension and gap width. See more details of pre-test procedures. procedure: Skinfold measurement can use from 3 to 9 different standard anatomical sites around the body.
