Q

internal moments are created by

A

contraction of the muscle, joint ligaments (restraint), and fascia/joint capsule (elastic properties)
- purpose is to counteract the external moments
- measures in newtons/ body weight

16
Q

power

A

energy/time
- greater power is created when it is performed in a shorter time
- measured in watts/joules per sec

17
Q

concentric power

A

when power is created (positive)

18
Q

eccentric power

A

when power is absorbed (negative)

19

A

at push off

20
Q

what type of power does the knee mostly do

A

eccentric power for absorbing GRF
