The purpose of this study is comparison of Telemark turn and Alpine (parallel) turn in visualization with graphs of distribution of strains on Telemark ski in turning. We had designed a measuring apparatus for strain on ski in turning with beam timing system. The measuring apparatus made us visualize the deflection of ski with graphs of distribution of strains on ski in turning. There are two types of Telemark ski, long and skinny one and short and fat one. We interested in the type of long and skinny Telemark ski. Because the long and skinny Telemark ski is so light and useful for ski touring which has so many up and down hill courses in snow hill area. The Telemark turn named for the region of its chief proponent, Norwegian Sondre Norheim. The characteristic of Telemark turn is heel-free position on inside and back ski in turning. The characteristic of Alpine (parallel) turn is a parallel stance in turning. We had measured the distribution of strains on Telemark ski in Telemark turn and Alpine (parallel) turn on 90m of length and 11° of compacted snow slope that had 4 flags at intervals of 20m. We had timed by 10 beams timing system at intervals of 10m . The Telemark ski had 8 strain gages on right and left side ski. The subject was a certified ski instructor both in Austria and Japan. The following results were obtained: 1) The graphs of distribution of strains in Telemark turn show bending on backside ski in turning. 2) The graphs of distribution of strains in Alpine (parallel) turn show a few bending on both side skis in turning.
