Q

during early flight what decelerates backward rotation of thigh?

A

Eccentric hip flexion

2
Q

during early flight decelerates backward rotation of leg/foot?

A

Eccentric knee extension

3
Q

during midflight what accelerates thigh forward?

A

Concentric hip flexion

4
Q

during late flight what rotates thigh backward in preparation for foot contact

A

Concentric hip extension

5
Q

during late flight accelerates leg backward, limiting knee extension; stops before foot strike (aided by concentric knee flexion to minimize braking at touchdown)

A

Eccentric knee flexion

6
Q

during early support minimizes braking effect of foot strike

A

concentric hip extension

7
Q

what resists tendency of hip/ankle extension to hyperextend knee; absorbs landing shock

A

Brief concentric knee flexion followed by eccentric hip extension

8
Q

what helps absorb shock and control forward rotation of tibia over ankle

A

Eccentric plantarflexion

9
Q

during late support what ecelerates backward thigh rotation; rotates trunk in preparation for
forward takeoff

A

Eccentric hip flexion

10
Q

what propels center of gravity forward

A

Concentric knee extension

11
Q

what aids in propulsion

A

Concentric plantarflexion
