世界上室内冰场的出现已经有七、八十年的历史了,近十几年来已发展到建造400米跑道的室内速滑比赛场地的规模.由于有了这些场地的保证,运动员就可以一年四季按计划需要进行训练了,它对运动成绩的提高起到了巨大的作用。但在雪上运动方面,近几十年内,世界各国只有利用塑料等化工材料代替天然雪而制成的“旱雪场”,只能进行模拟性的训练活动。 在寻找与建造天然雪或接近天然雪的“室内雪场”工程方面,日本一直是走在世界各国的前面的。1980年10月31日在日本的琦玉县建成了“狭山室内雪场”,雪道长350米,宽30米,“雪”厚35cm,坡度
The world’s indoor ice rink has been around for seven or eight decades, and in the last ten years it has grown to the size of an indoor speed skating stadium for the construction of a 400-meter runway. Thanks to these venues, athletes can play a The four seasons need to be trained according to plan, and it has played a huge role in improving sports performance. However, in terms of snow sports, in recent decades, only “dry snow fields” made of chemical materials such as plastic instead of natural snow have been used in various countries of the world to conduct only analogous training activities. Japan has always been in front of all the countries in the world to find and develop “indoor snow fields” that are natural snow or near-natural snow. October 31, 1980 in Saitama County in Japan built a “narrow mountain indoor snow field”, the snow is 350 meters long, 30 meters wide, “snow” thickness 35cm, slope
