Question | Answer |
Skinfold Basics | indirectly measures the thickness of subcutaneous adiose tissue, based on the theory that the amount of subcutaneous fat is propotional to the total amount of body fat & that 1/3 of total body fat is located subcuatanously or directly underskin, if |
skinfold correct procedure1 | taken on R side-identify, measure &mark the skfsite-place thumb/finger 8cm apart lift the fold-caliper placed on skin 1cm below pinch, perpendicular to sf, .5 b/w crease and base of fold-read caliper after 1-2sec-duplicate rotational measures w/e 1-2mm |
Erros can occur with skin foulds | reasons such as inexperienced technician, poor technique, improperly calibrated caliper and client factors |
What do make sure of when doing a skin fold | inform ath of ass. procedures &protect his/her privacy,b sure you only do sf analysis on skin thats dry,free of powder& lotion, avoid doing sf when the hydration level of your client is compromised-not following exercise, or when there is peripheral edema |
Equipment needed | high-quality skinfold calipers which will exert constant tension throughout the range of measurement, perferably metal calipers vs plastic, washable marker or surgical marker, calculator |
skin fold sites | abdominal, triceps, biceps, chest/pectoral, medial calf, midaxillary, subscapular, suprailiac, thigh |
Abdominal | verticl- 2cm right of umbilicus |
Triceps | Vertical- midway between acromion/olecranon |
Biceps | vertical-over belly of biceps, 1 cm proximal to the triceps |
Chest/pectoral | diagonal-mid way between axillary ligh and nipe(male_ |
Medial Calf | vertical-medial boarder, >circumference |
Midaxillary | vertical-midaxillary line, level of xiphoid process |
subscapular | diagonal-1-2 cm distal to inferior angle of scapula |
suprailliac | diagonal-line with the iliac crst, anterior axillary line |
thigh | vertical-anterior midline of thigh, between crease and patella |
Three sites for the joackson pollock 3 site equation for men | chest, abdomen, thigh or-chest, triceps, subscapular |
Three sites for the jackson pollock 3 site equation for women | triceps, suprailiac, thigh or-tricepts, suprailiac, abdominal |
body fat percentage | =(495/body density)-450 |
