What is a normal skin fold measurement?
Taking Skinfold Measurements
Skinfolds (mm) | Males (age in years) | Females (age in years) |
---|---|---|
20 | 8.1 | 21.4 |
25 | 10.5 | 24.0 |
30 | 12.9 | 26.6 |
35 | 14.7 | 28.5 |
What is subscapular skinfold thickness?
Skinfold thickness was measured from the left side of the body to the nearest 0.1 mm, using a Holtain skinfold caliper (Holtain Ltd., Crymych, UK), at the following sites: (1) triceps, halfway between the acromion process and the olecranon process; and (2) subscapular, approximately 20 mm below the tip of the scapula.
How are skin folds measured?
The skinfold is measured immediately above the iliac crest skinfold site. To do so, the tester should place the thumb over the iliac crest point and then measure the fold (it is taken near horizontally, but it follows the natural fold lines of the skin).
What is triceps skin fold thickness?
A value used to estimate body fat, measured on the right arm halfway between the olecranon process of the elbow and the acromial process of the scapula. Normal thickness in males is 12 mm; in females, 23 mm.
What is considered a skin fold?
: a fold of skin formed by pinching or compressing the skin and subcutaneous layers especially in order to estimate the amount of body fat.
What is the subscapular?
The subscapularis is the largest, strongest muscle of the rotator cuff. The rotator cuff muscles are important in shoulder movement and help maintain glenohumeral joint stability. The subscapularis muscle lies at the anterior surface of the scapula.
What are good skin fold results?

Is a 7 site or 3 site more accurate for measuring body composition for body fat percentage?
It is that a seven-site analysis provides a more accurate representation of overall body composition compared to the three-site because it incorporates subcutaneous adipose tissue values from more locations than the three-site estimation (1).
Are skinfold measurements accurate?
Skinfold Results Information The accuracy of skinfold measurements are within ± 3.5-5%.
Where is subscapular?
Subscapularis is a triangular shoulder muscle located in the subscapular fossa of scapula. Attaching between the scapula and the proximal humerus, it is one of the four muscles of the rotator cuff, along with supraspinatus, infraspinatus and teres minor.
Can you palpate subscapularis?
The subscapularis muscle belly can only be reached by bringing the hand in between the scapula and the thorax. It cannot really be palpated. The tendinous insertion on the lesser tuberosity, however, can easily be palpated.
Are skin folds accurate?
Administered correctly, skinfolds can give accurate results. These techniques are widely used in clinical and field studies because they are relatively easy to administer to large groups of individuals and the equipment is inexpensive (skinfold calipers, tape measure, and anthropometer).
What are the 5 skinfold sites?
Skinfold measurements
- Biceps skinfold (front side middle upperarm)
- Triceps skinfold (back side middle upperarm)
- Subscapular skinfold (under the lowest point of the shoulder blade)
- Suprailiac skinfold (above the upper bone of the hip)
What are the 8 skinfold sites?
The names of the skinfold sites are:
- Biceps.
- Triceps.
- Subscapular.
- Iliac Crest.
- Supraspinale.
- Abdominal.
- Front Thigh.
- Medial Calf.
How do skinfold calipers calculate body fat?
Whether you’re a man or a woman, take a pectoral, abdominal, thigh, biceps, triceps, subscapular, suprailiac, lower back, and calf measurement (in millimeters), then use the following equation to calculate your body fat percentage: Body Fat Percentage = (27 x sum of skinfolds sites) divided by bodyweight (lb.).
What is normal fat percentage in body?
According to the American Journal of Clinical Nutrition, there are healthy body fat percentages based on your age. For people aged 20 to 39, women should aim for 21% to 32% of body fat. Men should have 8% to 19%. For people 40 to 59, women should fall between 23% to 33% and men should fall around 11% to 21%.
Why is skinfold not accurate?
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 does subscapular mean?
The term “subscapularis” means under (sub) the scapula (wingbone). It is part of the four rotator cuff muscles, the other three are the supraspinatus, infraspinatus and teres minor muscles. The subscapularis is the largest and strongest muscle of the rotator cuff.
How do you know if your subscapularis is tight?
Pain in the shoulder (diffuse and sharp) with movement. Weakness/loss of shoulder stability. Referred pain in the neck, behind the shoulder blade, in the tricep/bicep, along the outside of the elbow, or down in the wrist and hand.
How do you measure subscapular skinfold?
Subscapular skinfold was measured in millimeters using the Holtain skinfold caliper by trained personnel at the inferior angle of the right scapula according to NHANES protocols. The protocol stipulates that each skinfold should consist of a double thickness of skin and underlying adipose tissue.
Where is the subscapula skinfold?
Subscapula Skinfold. Diagonal fold. Located 1 to 2 cm below the inferior angle of the scapula (the bottom of the shoulder blade) If you struggle to locate the bottom of the shoulder blade then ask your client to raise their arm up behind their back – this should make the scapula become more prominent.
Is subscapular skinfold associated with all-cause mortality?
However, after being adjusted for confounders (Model III), subscapular skinfold inversely associated with all-cause mortality (HR, 0.98; 95% CI, 0.97–0.99; P < 0.001) but showed no significant association with cardiovascular mortality (HR, 0.97; 95% CI, 0.94–1.00; P = 0.083).
What are skinfold measurements?
Skinfold measurements are cheap, not very painful and easy to perform, although practice is required. With the table of Durnin en Womersly (1974), the percentage of body fat can be read by a given age and sex. This table contains data for people aged 17 years and older. More information on skinfold measurements can be found in this article.
