Click here to get the slides for class 3.

Please note that these slides are for your personal use, and I ask that you not post them yourself anywhere on the internet.

1. Go to www.coloradomtn.edu/cll
2. Click on “Summit CLL Calendar” on the left of the web page
3. On the calendar, go to March 4 and click on “more events…”
4. An entry for the class should appear. Click on it.
5. You should now see a detailed description of the class. In the
   orange area above the detailed description there’s a line that says
   “Register and Pay for Non-credit Classes on WebAdvisor / Continuing
   Eductation”. Clink on the part that says “WebAdvisor / Continuing Education”.
6. Under the “Registration” heading on the page that now appears, click on “Register and Pay for Continuing Education Classes”
7. On “Register and Pay for Continuing Education Classes” page, he  search for the keywords “ski technique”. This will get you the place where you can actually start to register.

If you trouble with this procedure, I suggest calling CMC directly: 970-453-6757 or 970-468-5989.

Good luck!

Detailed charts with good navigability. Click on the chart you’re interested in, and window will appear that you can zoom in and pan around on. Not printable.

A nice simple, easy-to-read chart, with a table of movements and the muscles that produce them. Suitable for printing.

A very detailed chart with good illustrations and descriptions of functions.

Carlo Janka’s consistency is noteworthy. He doesn’t win many intervals, but he’s almost always in the hunt. And if you can be near the top in all the split times, you’ll finish well in a lot of races, and win some, too.

Janka carves short, clean arcs that he can get into with a direct line, and release from early. He accomplishes this with technical precision that’s belied by a relaxed and well balanced upper body. The precision comes from the accuracy of movements he makes with his legs. His carefully coordinated movents at the ankles, knees and hips control the total force on his skis and its distribution fore and aft, the direction his skis are pointed, and their edge angle with the snow. The precision of these movement enable him to make the turn he wants in the place he wants.

The total force is regulated by flexion and extension movements at the knee and hip. We can see this in the way he allows his knees to come up under him in the 7th frame. This absorbs some, but not all of the upward force exterted on him at the end of the first turn, keeping his skis in contact with the snow. The ankles control his fore-aft balance and the distribution of pressure along the length of the skis. He straightens his ankles in the transition to move pressure to the middle of the skis, and flexes them in the entry to the second turn to apply pressure to the skis’ forebodies. Turning movements of the femurs in the pelvis control the edge angles of the skis and the direction they are pointed, while turning the hip slightly toward the outside, in conjuction with Janka’s forward flex at the waist, puts his balance solidly on the outside ski. In frames 2 through 6 an inward rotation of his right leg in the pelvis produces the knee angulation that edges his outside ski. In the second turn, a similar movement of the left leg controls the edge of outside ski. Rotary movements of both legs in frames 6 through 9 release his edges and redirect the skis to the line he then carves through the second turn. Performing these tasks accurately with the lower body allows his upper body to remain quiet and relaxed.

When a skier’s upper body is more active than Janka’s, it’s often because the movements in the ankles, knees and hips are not as accurate, and the upper body must make compensatory movements. Such a skier may be fast much of the time, but is more likely than a skier like Janka to find himself recovering from a technical inability to execute an aggressive tactical decision. And that recovery often results in a slow interval time that, in spite of fast split times on the rest of the course, puts him behind Janka at the finish line.
