body composition goals
-people just want to gain muscle mass or lose weight
what is the crux of every disease in America
body composition
-many diseases have correlation with obesity or sarcopenia
in health + wellness, body comp is often reported as

anthropometry
measurement of the human individual
in general, how does body increase fay
increases all types of fat at the same time

-essential body fat
-storage fat
essential body fat
surrounds internal organs, fat in CNS, in bone marrow, mammary glands
storage fat is composed of
-subcutaneous fat
-intramuscular/visceral fat
describe relationship between body density + body composition
fairly linear
-not perfectly linear

health-related
if you lose body fat…

on average the human body has ____% water
50-65%
factors influencing BMI
-infancy + childhood

-athletes/athletic training
-military + civil forces personnel
-special health + clinical circumstances
proper skinfold technique
-take measurements on the right side of the body
-locate the site to be measured
-use a tape measure if needed to locate the correct anatomical site, mark site if necessary
-grasp the skinfold firmly with the thumb and index finger (NOT DIRECTLY on the SITE) approximately 1.5 inches to each side of the site (ACSM’s Health-Related Physical Fitness Assessment Manual)
-place caliper perpendicular to skinfold halfway between the crest and base of the fold
-release the caliper all the way so the caliper is applying the proper pressure on the fold
-read the thickness to the nearest 1 mm after approximately 2 seconds
-the measurements should be taken sequentially; cycle through all of the sites before taking the second measurement at each site
a minimum of ____ measurements should be taken at each site
2
if the measurements vary by > ____ mm, then a third measurement must be taken
2 mm
how long do we wait for skinfold
2 seconds
if we wait less than 2 seconds for skinfold…
we get a higher measurement than we should
if we wait more than 2 seconds for skinfold…
we get a lower measurement because fat displaces itself
if we had a very obese person that couldn’t do a skinfold, what is the best option
BIA
can weight loss be faster than weight gain
yes
weight loss is primarily dependent on
how large of an energy deficit the client can achieve
why does weight gain take longer
because of the time is takes for muscular hypertrophy to occur
weight loss/gain goals have high dependency on
the client’s diet
don’t overstep the scopes of your practice by prescribing what
a diet
-find a dietitian that you respect + refer clients to them
a client trying to lose weight should maximize what
their moderate-vigorous physical activity
