Question

which of the following occurs with open chain hip extension?
a) anterior pelvic tilt
b) posterior pelvic tilt
c) pelvic abduction
d) pelvic internal rotation

Explanation:

Open - chain hip extension involves the movement of the thigh relative to the pelvis. During open - chain hip extension, the hamstrings and gluteus maximus contract. The contraction of these muscles causes a posterior pelvic tilt. Anterior pelvic tilt would be more associated with hip flexion (e.g., when the iliopsoas is more active). Pelvic abduction is a side - to - side movement of the pelvis, and pelvic internal rotation is a rotational movement around the longitudinal axis of the pelvis, neither of which is the primary movement in open - chain hip extension.

Answer:

B. Posterior pelvic tilt
