Real vs Ideal
It is important to remember that children have not had the same opportunity to develop movement skills as adults. As well as learning the skills to ski or snowboard young children are also developing skills to perform all activities, e.g. walking on a slippery surface. Adults are able to learn and develop movements more precisely and accurately. As children have less strength and coordination, they may not be able to utilise the same movements with the same refinement and may substitute other movements in their place.
This does not mean that children are incapable of effective, efficient movements but rather it may take more time, practice and repetition. Real movements for children may involve larger muscle groups and more gross movement patterns. These will gradually come closer to ideal movements as the children grow older, bigger and become more experienced. An important part of the goal setting procedure is to identify real movements and plan the lesson to help the skiers come closer to ideal movements.
Ideal movements – movements that would be optimal for a given task.
Fore/Aft Movement
Ideal
- Joints flex evenly together
- Pelvis is centred over feet
Real
- Knee and hip flex more, ankle movements are not as co-ordinated and large muscle groups develop first
- Pelvis is behind feet in order to move centre of gravity over the middle of the skis. Head is proportionally bigger, centre of gravity is higher
Rotational Movement
Ideal
- Legs turn under the body as skis move through an arc
- Both skis steer progressively through the turn
- Upper body provides a stable unit for the legs to turn under
Real
- The whole body moves as a unit, smaller muscles of the lower legs are less developed than the main core muscles
- Pelvis drives through turn, steering the outside leg
- Upper body provides the main turning force or is not disciplined enough to be stable
Lateral Movement
Ideal
- Lateral movements of the feet, legs and hips engage and release edges
- Legs move together with the same movements, same edges are engaged
- Balance is directed over the outside ski
- Separation occurs between upper and lower body
Real
- Edges are engaged by the whole body moving inside or by outside leg bracing to use skeletal strength
- Stance tends to be wide to help balance, inside edges tend to be engaged
- Weight stays on both skis because of width of stance and tendency of body to move as a unit
- Upper body moves as a unit and is braced to make use of skeletal strength
Vertical Movement
Ideal
- Even flexion and extension of all joints allows skis to flow over terrain
- Movement is continual and consistent
- Muscular tension is used to control pressure
Real
- Knee and hip flex dominates, ski tends to bounce (overly stiff boots)
- Lack of coordination and disproportionate muscular development means movements are gross and inconsistent
