Body Composition 1 Flashcards
denitometry - what is it
scanning technique that measures the density of a material by analyzing how radiation passes through it
densitometry - hydro static weighing
immerse someone in water and measure the amount the water has been displaced
most widely used tech to determine body density
densitometry - hydro limilations
need to account for the resisdual lung volume during submersion
and
eval pts must tolertae the water
densitometry - plethysmography
calculates the body densoty utilzing the amount of air displacemnt during test within a specialized closed chamber
anthropometry meaning
the scientific study of the measurements and proportions of the human body.
omparative measurements of the body examining dimensions such as height and weight, body circumferences, and skin-fold thickness.
anthropometry - skin fold measure
the method determins the overall percentage of body fat through 9 standardized sites
anthropometry - skin fold measure limitation
need experienced manger
varience from standard base on age, gender, and ethnicity
skin fold measure - what side of the body
right
skin fold measure- how many measure
multible
how far should the skinfold calipier befrom the examiners hand
1 cm
skin fold measure - how long to wait before reading calipher
2 secs
what is BMI
a calculation that estimates body fat based on a person’s height and weight
what is bioelectrical impendance analysis
method a measuring the bodies comp using a small electric current
measure the opposition depending on the resistance to said current
what are the standare skin fold sites
abd
triceps*
biceps
chest/pects
medial calf
midaxiallary
subscapular*
suprailliac
thigh
BIA - eating
do not eat or drink for 4 hours prior
BIA - activity
no vogrous activitt 12 hours prior
BIA - pee
pee 30 mins before
BIA - alc
avoid 48 hours proir to test
BIA - water
avoid excessive water intake prior
what is BMI used of
used it ID increased risk of mortality and morbidity
BMI and obesity class 1
30 - 34.9
BMI and obesity class 3/ extreme obesity
> 40
what is normal BMI
18.5 - 24.9 females
12 -18 males
what is waist circumfrance used for
anthropometric measurement for assessing abd fat during weight loss treatment
what level do we take waist circumfrance at
iliac crest
take at the end of noraml exhalation
waist circumfrance > 102 cm (men) >88 cm (women) indicates increased risk for
DM 2
HTN
dyslipedemia
cardio disease
greater then >102 and >88 waist and BMI
should be considered one level above
BIA - and resistance to current
A greater percentage of body fat will yield a higher resistance to the current.
what is a stadiometer
device used for measuring height that typically consists of a vertical ruler with a sliding horizontal rod or paddle
how should your feet be when taking height
feat together
