摘要：Before World War II, Japan, which had been at the bottom of the world’s ski jumping ranks, leaped to the top with the guidance of the Norwegian Helset in January-March 1929. The purpose of this study was to clarify the state of the sport before Helset’s guidance and its influence on the ski jumping world thereafter, in an attempt to clarify the guidance on Schanze jumping technique given by Helset. The study revealed that before the arrival of Helset, the Hokkaido University ski club had studied Schanze jumping techniques and theories independently since around 1914, and had practiced the technique of landing while keeping the body upright in the air. At that time, neither the Schanze available nor existing techniques were anywhere near the world level, and global trends were insufficient. Helset consistently conducted repairs, guidance, model jumps, and lectures in Hokkaido, Tohoku, Shinetsu, and Kanto from January to March 1929. Helset’s technical guidance centered on the world’s top Tams type, which constantly fixes the body bent forward in the air, and the Schanze guidance centered on Straumann’s theory of creating a gentle elliptical slope. Upon receiving these instructions, the athletes increased their flight distance, and the Federation announced that it had renovated and rebuilt the Schanze, being able to hold a jump tournament. In addition, the government cooperated with the spread of the technology and the Schanze theory throughout Japan. Helset’s world-leading Tams-type technology and the Schanze theory were then consistently taught in regions where skiing was possible, leading to superior technical effects and improved facilities, thus raising the level of competition so that it approaching the world’s best.
