For each phase, determine what hip joint movements occur, and then list the scles primarily responsible for causing/controlling those movements.

Explanation / Answer

1. In push up in initial movement (lifting phase), the movement is hip extension,agonists(contraction type) are adductor magnus, semitendinosus, semimembranous, biceps femoris, gluteus maximus, psoas major, minor, rectus femoris, sartorius , gluteus minimus, secondary movement (lowering phase) movement is hip extension, agnoists(contraction type) adductor magnus, gluteus maximus, gluteus minimus, semitendinosus, semimembranous, 2.in squat in initial movement (lifting phase) the movement iship flexion and adduction, agnoists(contraction type) are tensor fascia, adductor brevis, adductor longus, adductor magnus, in secondary movement (lowering phase) movements hipextension and agnoists (contraction phase) biceps femoris, gluteus maximus , gracilis, pectineus, adductor brevis, adductor longus, adductor magnus. 3. Dead lift in initial movement(lifting phase)the movement is hip extension and internal rotation and adduction, agnoist(contraction type)gluteus maximus, gracilius, pectinous adductor brevis, adductor longus, adductor magnus semitendinosus, semi memebranous, in secondary phase(lowering phase)movement is hip flexion and agonists are tensor fascia latae, gracilius, semitendiousus, semi membranous, pectineus, adductor brevis, adductor longus. 4.Hip sled: lifting phase, movement is hip extension, agonists, gluteus maximus, gracilis, illacus, psoas major, psoas minor, rectus femoris, sartorius, pectinus, secondary (lowering phase) movement is hip flexion and agonists are tensor fascia latae, gracillis, semitendinoius, semimembranoius, pectinous, adductor brevis, adductor longus , adductor magnus. 5. Forward lunge: lifting phase movement is hip flexion and agonists are gluteus minimus, tensor fascia latae, gracilus , semitendinous, semimembranous. secondary (lowering phase) movement is hip flexion and agonists are gluteus maximus , gracilis, rectus femoris, sartorium. 6. Rowing exercise: initial phase (lifting movement)is movement is flexion is tensor fascis, adductor longus adductor magnus, gracilius , adductor brevis, secondary phase(lowering phase)extension movement and agonists is gluteus maximus, gluteus medius, gluteus minimus, 7. stair machine:initial phase: (lifting movement) upward movement is extension agonist aregluteus maximus and minimus, biceps femoris, semimembranosus, semitendinosus, rectus femoris, secondary phase( lowering movement) movement is flexion and agonist are tensor fascia lata, psoas major psoas minor, iliacus.
