Question

When pushing off the ground in running and jumping activities, the action at the hip is (flexion /extension). The (anterior/posterior) group of muscles provides this energy, with the ____ being the prime mover.

Answer 1

In running and jumping, the hip action is an extension, powered by the posterior muscles, with the gluteus maximus being the prime mover.

Step-by-step explanation:

When pushing off the ground in running and jumping activities, the action at the hip is an extension. The posterior group of muscles provides this energy, with the gluteus maximus being the prime mover.

In the limbs, flexion decreases the angle between the bones, while extension increases the angle and straightens the joint. In the lower limb, any posterior-going motion of the thigh is an extension. This means during activities like pushing off the ground, the hip is extending. The posterior muscles of the femur, specifically the hamstring group, aid in this movement, but the gluteus maximus is the main muscle responsible for hip extension, making it the prime mover.
