NUTR 442 - NUTRITION ASSESSMENT LABORATORY
EXPERIMENT 3 - ASSESSMENT OF BODY COMPOSITION LABORATORY II
OBJECTIVE: To give students the experience in collecting and analyzing
anthropometric and bioelectric impedance data useful in the determination
of body composition. In addition, students will learn to calculate body
composition using data from hydrodensitometry.
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. If direct measurement on your skin is
not desirable for certain sites, try to wear thin and lightweight garments. For BIA
measurements, we need to have access to the skin on the back of your hand/wrist as well
as the top of your foot and ankle. For accurate determination of body composition as
assessed by BIA, you need to be normally hydrated and have a normal body temperature.
That means that you should not exercise that morning, drink plenty of fluids, and not eat
for at least two hours prior to lab.
DATA TO BE COLLECTED:
1. Gender
2. Age
3. tricep skinfold thickness
4. bicep skinfold thickness
5. subscapular skinfold thickness
6. suprailiac skinfold thickness
7. Bioelectric resistance value
8. Body weight (kg)
9. Height (inches)
