Kinetic data analysis Flashcards
1
Q
What units can force be expressed in
A
Newtons (N) or Bodyweight (BW)
2
Q
What to consider with vertical forces
A
Is the force working with or against gravity
3
Q
What to consider with horizontal forces
A
What type of movement is it and where is the force directed
4
Q
Fz =
A
Vertical force
5
Q
Fy =
A
Anterior/posterior force
6
Q
Fx =
A
Medial/lateral force
7
Q
What is loading rate
A
Rate of force change
Represents shock imposed on MS system
8
Q
Loading rate equation
A
Loading rate = impact peak force (N)/ time to impact peak (s)
9
Q
What is the unweighting or unloading phase
A
When the vertical GRF drops below body weight
10
Q
How can you calculate velocity and displacement
A
F = ma
11
Q
Impulse momentum equation
A
(impulse) Ft = mv1 - mv2 (change in momentum)
