Explanation:
Detailed explanation-1: -Passive Insufficiency: Hamstrings are pulled taut into lengthened position as hips are fully flexed and knees fully extended.
Detailed explanation-2: -Passive muscular insufficiency of the gastrocnemius muscle acts on a pathologic foot, which is poorly prepared to accept the forces from the gastrocnemius-soleus complex. In this manner, a normal gastrocnemius muscle exerts abnormal forces across the foot.
Detailed explanation-3: -Passive insufficiency of rectus femoris muscle occurs due to excessive stretching when there is knee flexion with hip extension.
