Mission accomplished! You display a constant down the hill speed from turn to turn in all 3 clips. It's difficult to quantitatively measure speed from video, but rhythym is a fair approximation if turn size is constant and that can be measured via the pole touches. Rhythym in first clip has pole touches on the same turns consistently between 60-64 frames apart
(I measure from where the pole is vertical), 70-79 in the second and 59-67 in the last clip. Raw video clips run 30 frames per second. I use
V1 software to view clips. V1 shows the frame count in addition to the elapsed time. This lets me measure the time between turns more accurately. A 9 frame difference means there is less than a third of second difference between the shortest pair of left/right turns and the
One common strong feature of the turns in these clips is the amount of directional control of the skis. The bottom half of the turn has a lot of carving action going on. What else makes these turns look so good?
Lets look at some of the effective visual cues:Balance
- flexing originates in the ankles and is supported by the knees,hips and lower back
- hips are centered throughout the turn, promoting a movement forward through the finish and into the new turn (most visible in the bottom half of the turns)
- upper body more vertical than the lower body
- skiers hands in front of the body
- Tension of the inside ankle directs movement forward and laterally for edge angle adjustments (most visible in the bottom half of the turns)
- The skiers legs turn underneath a strong/stable torso to help guide the skis through the turn
- Femurs turn in the hip sockets (instead of the entire hip coming around)
- The skis flow evely and smoothly over the terrain (the ski tips do come off the snow occasionally, but they are smoothly reapplied)
- The skis bend progressively (we can't see much of this, but the tips of the skis can be seen bending)
- The skiers upper body remains quiet and disciplined
- The skis continue to move forward along their edges throughout the turn (most visible in the bottom half of the turns)
We know that dchan is working on level 3 certification. The following comments are submitted with this in mind. As much as I like these turns, I can see where an examiner could easily say "Fail!" because the top parts of the turns are not round enough (i.e. those pesky pivots and skids). It's important to understand that the short radius turn as an exam task is meant to highlight efficient and inefficient movements. The task focus on speed control as the main goal is a misdirection. If you focus on efficient movements, speed control is a result. If you focus on speed control, inefficient movements are a result.
The intent here is to turn good turns into "knock 'em dead" turns. What is causing the lack of roundness in the top part of the turn? To me it looks like a slight heel push (the pivot) to get the skis turned through the fall line. Why is this necessary? It's because the skis are not getting pressured on the inside edges above the fall line. TDK's suggestion to flex to the inside leg is half of the solution. SSG's ideas of counter and angulation are almost the other half. Unlike SSG I don't want to see counter held all the way through a turn. I'd rather see counter
created at the end of a turn (going across the fall line) and returned to zero in the fall line. What I see in these clips is the shoulders pointed to the outside of the turn in the fall line and more aligned with the lower body across the fall line. Dchan's overall angulation is fine,
but I'd like to see more boot tipping (knee angulation) early in the turn. The idea here is to get the skis more aggressively pressured on the new edge early in the turn by starting from a countered position, moving the center of mass directly to the inside of the new turn and using more inside leg flexion to allow more knee angulation for more aggressive tipping.
Getting the skis to be already turning before the fall line should eliminate the need to help them turn through the fall line.
So how do we develop this movement? I don't know of a sure fire cure, but this is the reason I asked about sidecut. Short turn radius skis give the most feedback when you do make these movements. The skate to shape drill is great at reinforcing the movements, but not as good at
developing the movements as using a skating move to initiate medium radius turns. One exercise I've used successfully in the past is an extreme turn finish up the hill combined with an extreme down the hill pole touch (causing an extreme layed out position to start the new turn). Other
tasks focused on keeping the shoulders level can also help (e.g. keeping both pole tips dragging in the snow at all times; no poles, bamboo across the shoulders - keep the boo level to the slope). I've had luck with a few people getting them to try to rotate their inside butt forward during turn initiation (not as "how to" movement, but as a "feel what happens when you do this" movement). Variations of javelin turns (lifting one ski off the snow and rotating it into the new turn or against the new turn!) or white pass turns can do the job. The last suggestion is to try is 10 toes (focus on getting all ten toes to point down the fall line before letting the skis cross the fall line. This won't directly help short turns, but it does teach patience to let the skis do the turning.
I want to add some still frames and explanations, but this will have to wait till later in the week.
