Abductors enable efficient bipedal motion by contracting parts of the gluteals that attach to the ilium and allow humans to step on one foot at a time.
a. True
b. False

Since , abductions, particularly the minimus and gluteus medius , are active on the side of the leg which is in contact with the ground . This is to avoid the tendency of gravity to cause the downward motion of the hip on the opposite side . In addition, the lateral muscle and paraspinal muscles of the trunk are active on the side of the swinging leg to avoid the downward motion of iliac crest on side .
