What is the agonist muscle in hip flexion?
Rectus femoris+ anterior thigh; quadriceps+ extension of leg at knee Vastus lateralis+ lateral anterior thigh; quadriceps+ extension of leg at knee Vastus Medialis+ medial anterior thigh; quadriceps+ extension of leg at knee Vastus intermedius+ deep anterior thigh; quadriceps+ extension of leg at knee Sartorius (*) parallel strap-like muscle that crosses thigh flexion of knee forward Biceps femoris* posterior thigh; hamstring* flexion of leg at knee Semitendinosus* posterior thigh; hamstring* flexion of leg at knee Semimembranosus* posterior thigh; hamstring* flexion of leg at knee
What are examples of reverse muscle action of the human body?
The rectus femoris THe regular Muscle Action is hip flexion with knee extension, as in kicking a ball or doing a straight leg raise The reverse muscle action is still hip flexion with knee extension, but as in doing sit-ups while lying supine with knes straight ahead
Leg extension exercises focus on which muscle region of the body?
Leg extension exercises focus on quadriceps.
What muscle turns your leg?
Hip flexors mostly.
Why does rectus femoris become active in leg extension?
The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
Which muscle group is primarily worked by the leg extension?
the quadriceps
What muscle is involved in the crossing of one leg over the other in the sitting position?
sartorius
What muscle is the primary mover in the leg extension?
The vastus medialis is involved in leg extensions.
What types of exercises are plantar flexion hip flexion hip extension knee flexion and side leg raises?
balance
What muscle is pulled when the knee is forced into extension when the hip is already fully flexed?
the hamstrings :)
In running the action at the hip joint is what in reference to the leg moving forward?
Flexion and extension
What is the action of the quadriceps muscle group?
Flexing the thigh, extending the leg, adducts leg
