Question 1

What forces are needed for rotation?

Answer 1

Internal forces like torque

Question 2

q-angle and it values

Answer 2

measured from hip to patella tendon
values: men 14, women 17
limb proportions affect motions
-those with wider hips typically have an increased chance of knee injuries

Question 3

3 ways POSSUM observations help a novice observer

Answer 3

observation
core concepts
evaluating

Question 4

Open Kinetic Chain example

Answer 4

dumbell curl

Question 5

Closed Kinetic Chain example

Answer 5

squat

Question 6

Kinematic Characteristics

Answer 6

displacement, acceleration, and velocity

Question 7

Kinetic Characteristics

Answer 7

friction, pressure, gravity

Question 8

Kinetic Perspective

Answer 8

forces involved

• How much force was absorbed by the body when making the change in direction?
• What force makes the change in direction possible?
• How much force is needed to tear an ACL?

Question 9

Kinematic Perspective

Answer 9

How fast was the player moving when the injury occurred?
How far did the player travel at this speed before the injury?
How much did the player accelerate/decelerate in order to change direction?

Question 10

Coefficient of restitution (e) example

Answer 10

i.e. a golf ball will have a higher CoR than a rock when dropped from any height (0.00= plastic, 1.00= elastic)
