NUTR 442 - NUTRITION ASSESSMENT LABORATORY
EXPERIMENT 2 - ASSESSMENT OF BODY COMPOSITION LABORATORY I
OBJECTIVE: To give students the experience in collecting and analyzing
anthropometric data useful in the determination of body composition.
PRE-LABORATORY PREPARATION:
1. Read this document carefully before your laboratory period. It will help prevent you
from making mistakes, speed up your work, and prepare you for asking any questions
about procedures that need clarifying.
2. Dress appropriately for this laboratory. For skinfold thickness measurements, we will
need access to the top of your shoulder, tip of the elbow, tricep, bicep, the scapula on
your back, area just above the top of your pelvis. For circumference measurements, we
will need access to your thigh, calf, hip, waist, forearm, and upper arm. We will also be
measuring your height and weight again. If direct measurement on your skin is not
desirable for certain sites, try to wear thin and lightweight garments.
DATA TO BE COLLECTED:
1. Age
2. tricep skinfold thickness
3. bicep skinfold thickness
4. subscapular skinfold thickness
5. suprailiac skinfold thickness
6. body circumferences appropriate for age and sex
7. height
8. weight
9. Hydrodensitometry values (HPELS room 202, MW 2-4, TR 1-5, no food or drink
2 hrs prior, swim suit and towel, sign up for reservation, get data from
technician including weight in air, weight in water, density of water, residual
lung volume, volume of gas in GI tract; if RV not available, estimate from
equation on p198; if VGI not available, use 0.1 liters)
DETERMINE THE FOLLOWING:
1. Percentile tricep skinfold (Appendix N, p 545-546)
2. Percentile subscapular skinfold (Appendix O, p 549-550)
3. Percentile tricep skinfold + subscapular (Appendix P, p 551-552)
4. Body fat % by skinfold method of Durnin & Womersley (table 6-9, p 200);
conversion of BD to %BF using both Brozek and Siri equations (p 200)
5. Body fat % by circumference method of Katch & McArdle (see below)
6. Body fat % by hydrodensitometry (figure 6.37, p 202-203) Use the value of %
body fat provided by the technician in the Exercise Science Lab. We will do
the calculations ourselves by hand next lab period. Be sure to get all of the

Body fat % by hydrodensitometry (figure 6.37, p 202-203) Use the value of % body fat provided by the technician in the Exercise Science Lab. We will do the calculations ourselves by hand next lab period. Be sure to get all of the

RAW DATA that they collect as well. They typically only give subjects the final % body fat. You need to get your underwater weight, your weight in air, your residual lung volume, and the density of the water (or the temperature of the water).

  • Personally collect the data on two of your laboratory classmates. Get the data on yourself from one of your classmates.
  • For each student, calculate or determine each of the above. (# 1-6).
  • Write a brief SOAP note for each of the three students you have collected data for.
  • Assess energy stores based on tricep skinfold, subscapular skinfold, sum of tricep and subscapular skinfolds (percentile assessment).
  • Assess body fat values based on Table 6.11, p 201
  • Note whether you find any consistent differences between the % body fat as determined by skinfold measurements and the hydrodensitometry values given to you by the exercise science students.
  • Due next lab class period. Estimation of Body Composition Using Body Circumference Measurements. Equations derived from “Nutrition, Weight Control, and Exercise, F. Katch & W. McArdle, 2nd ed., 1983). Younger Women (17-26 years) % body fat = (abd circ x 1.34) + (thigh circ x 2.08) – (forearm circ x 4.31) – 19.6 (or 22.6) Older Women (over 26 years) % body fat = (abd circ x 1.19) + (thigh circ x 1.24) – (calf circ x 1.45) – 18.4 (or 21.4) Younger Men (17-26 years) % body fat = (upper arm circ x 3.70) + (abd circ x 1.31) – (forearm circ x 5.43) – 10.2 (or 14.2) Older Men (over 26 years) % body fat = (buttock circ x 1.05) + (abd circ x 0.90) – (forearm circ x 3.00) – 15.0 (or 19.0) All circumference measurements are in inches. Values in parenthesis are used if the individual participates in more than 240 minutes of vigorous activity per week. NUTR 442 - NUTRITION ASSESSMENT LABORATORY
