Body Composition Measurements

Mass: The amount something or someone weighs.

  1. Consult your professional/s for treatment and rehabilitation as these are academic principle guidelines only and not prescriptive.
  2. ASSIC does not dispense medical and/or exercise advice.
  3. Consult your professional regarding exercise, treatment and rehabilitation exercise regimes and medical advise.
  4. The contents of the following web page are principle guidelines and must be utilized under the supervision of a relevant medical and/or exercise professional.

Body Mass Index (BMI):

This is the ratio of the person’s body weight to their height. BMI is calculated by dividing weight in kg by square of height in meters. BMI is a good indication of body composition, especially when the individual has a high Fat percentage. When an individual is classified in the overweight or obese categories, this increase the risk of developing chronic illness such as heart disease, diabetes, hypertension, etc.

BMI is not a true reflection of someone’s body composition, if the body fat percentage is low. For example in body builder who have BF % below 10, then the sum of skinfolds should be taken to calculate this.

From the results of the calculations classified into different categories:

Classifications BMI
Underweight Less than 18.5
Normal 18.5 – 24.9
Overweight 25 – 29.9
Obese 30 – 34.5
Severely Obese 35 – 39.9
Morbidly Obese 40+

Skinfolds

Skinfolds provide a good indication of the level of fatness located over the body in the subcutaneous storage areas. A skinfold caliper is used to measure the various skin sites, usually these measurements are taken and calculated by a trained professional. These measurements are used to calculate a predicted body fat percentage. This method is popular as it is quick, cost effective and non-painful procedure. When the measurements are taken, the individual is in minimal clothing to expose the various site.

The various sites locations can be found on the ASSIC testing app. These skinfold sites include:

  • Triceps skinfold: mid-point at the back of triceps
  • Biceps skinfold: front of arm above the cubital fossa
  • Suprailiac skinfold: in the midaxillary line above the iliac crest
  • Subscapular skinfold: below the shoulder blade with shoulder relaxed. Take measurement 45 degrees to the horizontal
  • Pectoral: Point between the axilla and nipple, high on anterior axillary fold
  • Anterior thigh : Midpoint of front (anterior) of thigh midway between knee cap (patella) and the top of thigh crease (inguinal fold)
  • Calf: Inside (medial) area of the largest calf circumference area

Calipers

  • Skinfold thickness is measured using precision calipers
  • The calipers measure the compressed double fold plus the skin
  • There are 3 types of calipers used and they include Harpenden, Lange and Holtain

Calculation and result interpretation:

  • Average sum of 7 sites
  • The average range vary for specific sports
