But let's get even pickier and consider two outcomes of tipping. When I tip my foot I try to keep my toes from pointing in a new direction (in other words the foot is still pointing straight ahead). This is very different than the guy that tips his foot and lets the foot rotate with femur rotation (so that they toes are now pointed into the turn). Two very different outcomes that both have femur rotation.
There are movements that we make with our body that apply rotational torque on our feet both ways.
From a square stance
Movements used in skiing that apply rotational torque on our feet into the turn are:
- rotating our upper body into the turn (upper body rotation, antisipation)
- rotating our hips into the turn (hip rotation)
- rotating our femurs in our hipp sockets into the turn (pointing of knees)
Movements used in skiing that apply rotational torque on our feet towards the outside of the turn are:
- rotating our upper body towards the outside of the turn (counter/counteraction)
- rotating our hips towards the outside of the turn (counter/counteraction)
Movements used in skiing that do not apply rotational torque on our feet eather way of the turn are:
- moving our hips sideways (angulation/counterbalance)
By combining tipping (neutral), counter (rotate out) and knee pointing (rotate in) we can adjust the torque and try to keep it to a minimum. PSIA manual says that depending on snow conditions we need to vary the ammount of rotation and that sounds like a good consept. In powder we need more rotation than on flat easy gromers or when carving.
