Anthropometry Flashcards
Anthropometry
Measurement of the human body segments
Anthrompometric Measures
-mass
-moment of inertia
-COM
mass
amount of matter in a body, it’s resistance to acceleration
COM
center of mass: balance point about which free rotation occurs, all mass is equally distributed
MOI
moment of intertia: property describing resistance to angular acceleration, increases as mass is located farther from axis of rotation
inertial properties
mass, moi, com
body segments
-rigid body structures
-may be composed of small segments
-may be combined (HAT)
examples of body segments
feet, shank, thigh, trunk, upper arm, forearm, hands, head
Sum of Segment
mass * total mass
Segment average
(x1+x2)/2 =
COM Formulae
xcom
x coordinate com
m1
mass of first segment
m2
mass of second segment
mb
mass of whole body
x1
x coordinate of first segment COM
