Body Segment Parameters Flashcards
1
Q
What does the average density depend on?
A
Somatotype - body build
2
Q
Specific gravity
A
Ratio of density to water
bone - > 1.8
muscle + tissue - just over 1
fat < 1
3
Q
Do segments have uniform densities?
A
No, this is an assumption therefore all answers are approximations
4
Q
Two trends in segment density
A
- distal segments tend to have a greater density than proximal ones
- density of segment increases with whole body density
5
Q
CoG
A
CoM in one axis only, the one defined by the direction of gravity
6
Q
Foot
A
ankle + metatarsal
7
Q
Leg
A
lateral femoral condyle + ankle
8
Q
Thigh
A
greater trochanter + lateral femoral condyle
9
Q
Multi-segment mass and CoM samples need to be
A
updated every time segment
10
Q
Which segment dominates the CoM calculation for the total leg
A
Thigh segment as it makes up around 2/3 of the total mass
