Study of the Technique of "Kakaekomi Okuridashi turn" ("hold-in-and-push-forward turn") in Ski

Abstract

1. In the developmental history of the ski technique, Austrian ski method which is chiefly composed of Beinspielen made an outstanding step. It was produced, however, based on "Stemmen", which acts as a factor constraining the skiing speed control. 2. By use of a Milliken high speed camera, precise motion pictures of a new ski technique "Kakaekomi Okuridashi Turn" ("hold-in-and-push-forward-turn"), which is to remove the above constraining factor were taken, and analyses of these pictures made clear the tecnical elements of the "Kakaekomi Okuridashi Turn". 3. In this turning technique which is different from those of the conventional skiing technique, steering of ski on the snow by the strong will of skier is constantly by working as well as all the other turning techniques was pointed out. 4. Electromyographical studies with a radio-telemeter were made to compare the "Kakaekomi Okuridashi Turn" with a conventional technique of about same level, each subject performing the two techniques at a time. By the Electromyograms, it was ascertained thet the working of antagonist muscles of the leg in terms of "flat and closely-touched-on the snow" and a series of action during the turn was esseetial in the new technial in the new technique, and this will help as an instructional suggestion in skiing techniques. 5. The establishment of the technological scientific research system in this field of studies by synchronizing the photographical analyser with a apparatus is hoped. Furthermore, the laboratory research should be applied into practical activities.
