density of water
1
density of fat
.90
density of LBM (muscle)
1.1
Body composition %fat health standards
men 10 to 20 % healhty
women 20- 32 % healthy
men 10-12 % and women 18-22% lower is highly fit or athletic
lower then 5% men and 10-12% women is unhealthy
body composition
components of body tissues
lean body mass
muscle, bone, water
elevated fat levels increases
type 2 diabetes, heart problems, CAD, heart attack, stroke, CHF, hypertension, cancers, non-alcoholic fatty liver disease
reduced muscle mass causes
generalized weakness, decreased functional capacity, increased fall risk, lower bone mass, contributes to type 2 diabetes
body composition measurements methods technologies
BMI skin fold DEXA Bod pod BIA hydrostatic weight girth/circumference
BIA
bioelectrical impedence analysis
how to calculate BMI (kg, m)
weight / height^2
conversion of in to cm
1 in = 2.54 cm
conversion of lbs to kg
1 kg = 2.2 lb
BMI standards
<18 underweight 20-25 healthy 26-30 overweight 31-35 obese I 36-40 obese II >40 obese III
3 skinfold sites for men
chest, abdomen, thigh
3 skinfold sites for women
triceps, suprailliac, thigh
body density conversion
495/BD-450
why measure waist circumference
single circumference different muscle and fat
visceral fat
visceral fat
bad health outcome, bad molecules and close to primary organs
how to measure skin folds
calliper
what is a skin fold
subcutaneous fat between muscle and skin
skin fold sites
abdominal, triceps, chest, midaxillary, subscapular, superilliac, thigh
abdominal skin fold site
vertical fold 2 cm to the right side of the umbilicus
triceps skin fold site
vertical fold, on the posterior midline of upper arm, half way between the acromion and olecranon processes, with arm held freely to the side of the body
