Q individual variations in iip mobility

Regardless of Individual muscle elasticity and ligamentous tension, it is mainly the shape of the bones of the coxofemoral joint that is responsible for hip mobility. The configuration of the bone is most Important In hip abduction.

Example

• When the neck of the femur is almost horizontal (coxa vara) and associated with a well-developed superior rim of the acetabulum covering the head of the femur, abduction movements are limited.

• When the neck of the femur is close to vertical (coxa valga) and associated with an undeveloped superior acetabular rim, abduction movements are facilitated.

Therefore, it is useless to try to raise the leg high laterally if your hip joint is not made for It.

ATTENTION

If hip abduction is forced, the neck of the femur will butt up against the rim of the acetabulum, and the pelvis will tilt onto the head of the opposite femur to compensate for lateral extension of the leg. When some people perform sets of forced abductions, over time microtrauma may occur, which develops excessive growth of the superior rim of the acetabulum, limiting the mobility of the hip and risking painful inflammation.

Femur Horizontal

An almost horizontal neck of the femur is referred to as a coxa vara. It limits abduction movements because It butts up against the rim of the acetabulum sooner.

An almost vertical neck of the femur is referred to as coxa valga. It allows greater abduction movements.

THE MOVEMENT

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
