Final answer:
During normal heel strike, the hip is flexed to about 30 degrees to help absorb impact and stabilize the lower limb. The hip essentially prepares to absorb impact and provide stability for the rest of the lower limb during the stance phase of walking or running.
Step-by-step explanation:
During a normal heel strike, the hip is typically flexed to an angle of approximately 30 degrees.
This is part of the gait cycle where the foot makes initial contact with the ground.
Heel strike is the phase where the heel touches down before the rest of the foot follows in plantar flexion, a movement at the ankle in which the foot bends down.
The hip essentially prepares to absorb impact and provide stability for the rest of the lower limb during the stance phase of walking or running.
