Hip Internal Rotation
-Gluteus Minimus
Hip Flexion
-Psoas -Iliacus (Iliopsoas) -Rectus Femoris -Pectineus
Muscles of the posterior compartment
-hamstring group •Biceps femoris •Semitendinosus •Semimembranosus
Muscles in the medial compartment
-primarily adductors •Adductor brevis •Adductor longus •Adductor magnus •Gracilis
Muscles in the anterior compartment
-primarily knee extensors •Rectus femoris •Vastus medialis •Vastus intermedius •Vastus lateralis •Sartorius
Hip Adduction
-Adductor Brevis -Adductor Longus -Adductor Magnus -Gracilis
Hip Extension
-Gluteus Maximus -Biceps Femoris (Long Head) -Semitendinosus -Semimembranosus
Hip External Rotation
-Gluteus Maximus -Six Deep External Rotators
Hip Abduction
-Gluteus Medius
Identify movements of joints (pictures)
Flexion, extension, abduction, adduction, internal and external rotation, diagonal adduction and abduction, anterior and posterior pelvic rotation, right and left lateral pelvic rotation, right and left transverse pelvic rotation
What does pelvic rotation help to increase in kicking?
Greater kick distance and speed
At which three other joints does movement occur during pelvic rotation?
Right hip, left hip, lumbar spine
Know joints involved/type (Multiple Choice)
acetabulofemoral joint- enarthrodial symphysis pubis- amphiarthrodial sacroiliac joint- amphiarthrodial
Why is the structure of the hip joint relatively stable?
bony architecture, strong ligaments, large supportive muscles
What three movements is the sartorius involved in that gives it the name the "tailor's" muscle?
hip flexion, external rotation, knee flexion
In which tight muscle does compression of the sciatic nerve sometimes occur?
piriformis
What muscle is important in helping direct the leg forward so the foot is placed straightforward in walking and running?
tensor fascia latae
