Fundamental terminology for coaching nordic skiing.
It is important to use consistent vocabulary while teaching. If needed, explain it in other words, but keep consistency as a whole.
Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies and even light and sub-atomic particles. That includes you and me.
- Forward momentum relates to one’s center of gravity being forward from a neutral position (standing).
- Without weight shift on to the other leg or intervention of the poles, face planting would unfortunately occur.
- Lean forward as a whole, do not just bend forward with your butt sticking the other way, it would not affect the center of gravity.
WEIGHT SHIFT or WEIGHT TRANSFER
Consists of transferring one’s weight from one leg to the other. There is no lag time where the weight is evenly distributed on both legs. The transfer from one leg to the other is immediate.
Weight shift allows for:
- A better propulsion
- Exponential gliding time from that propulsion
- Forward momentum
- Time (to angle or place your ski where needed)
The weight shift is the same in classic
Picture 1: equal distribution of the weight on both legs
Picture 2&3: Weight transfer from one leg to the other
Alignment relates to forward momentum.
In other words, to go from A to B the most direct route is a straight line.
- Every movement involves specific muscle actions.
- If we want to go forward using forward momentum as well as gravity, it requires movements to be aligned into the direction we are going.
- For example if I am going forward I want to avoid every parasite activity that would counteract my forward motion (Dropping the hip out of alignment)
Picture 1: The hip falls out of alignment and opens. The core cannot stay involved.
- It will lead the tip of ski to dig in the snow and the ski to lose speed
- The weight transfer will be delayed. (Time for the hip to be back in place before next transfer)
Picture 2: It is important to keep alignment to keep the right timing
