1

during early flight what decelerates backward rotation of thigh?

Eccentric hip flexion

2

during early flight decelerates backward rotation of leg/foot?

Eccentric knee extension

3

during midflight what accelerates thigh forward?

Concentric hip flexion

4

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

Concentric hip extension

5

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

Eccentric knee flexion

6

during early support minimizes braking effect of foot strike

concentric hip extension

7

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

Brief concentric knee flexion followed by eccentric hip extension

8

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

Eccentric plantarflexion

9

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

Eccentric hip flexion

10

what propels center of gravity forward

Concentric knee extension

11

what aids in propulsion

Concentric plantarflexion
