Would like some insight into the following from the PSIA technical manual on page 22.
"The greatest degrees of hip angulation come from a combination of leg rotation, abduction, and adduction of the femurs (see Chapter 4: Biomechanics), and torso flexion, primarily at the hip joint."
Is it possible someone can explain this is in easier terms?
Is there a picture of video presentation of this with regard to the combination of leg rotation, abduction, and adduction and possibly how changing one or any of those reduces or increases hip angulation?
Wouldn't leg rotation plus adduction reduce angulation? What am I missing?
As a reference, the technical manual defines the following...
Leg rotation = Movement of the lower body to make the skis turn. This includes elements of rotation from the femur in the hip socket and lower leg (below the knee) rotation.
Abduction = Movement of a limb away from a body's midline.
Adduction = Movement of a limb toward the body's midline.
Can't find a definition of torso flexion. What is it? Core muscles flexed?
