A few cards from the deck
Iliopsoas: what is it?
Show the answer
The iliacus and psoas major together, from the lumbar spine and pelvis to the lesser trochanter.
The most powerful hip flexor.
Standing on the right leg, a runner's pelvis drops to the left. Which muscle to strengthen?
- The right gluteus medius
- The left gluteus medius
- The left iliopsoas
- The right adductor longus
Show the answer
The right gluteus medius
The standing leg's abductor holds the pelvis.
Gluteus maximus: what is it?
Show the answer
The bulky buttock muscle, extensor and lateral rotator of the hip.
It works hard to climb stairs or sprint.
Why does a tight iliopsoas increase the lower-back arch?
- It attaches to the sacrum and tilts it backwards
- It attaches to the lumbar vertebrae and pulls them forward
- It extends the hip and straightens the pelvis
- It attaches to the ribs and pulls them towards the pubis
Show the answer
It attaches to the lumbar vertebrae and pulls them forward
The psoas links the spine directly to the femur.
