The classical abseil taught on the course was deemed to be too onerous and an alternate was investigated with a group of students which would remove the issues of rope burn, lack of sufficient control and toppling over backwards which is a common problem with the standard classical abseil. Later on that same year, the method was demonstrated to the UIAA International Training Standards Working group seminar in Chamonix - France, and was dubbed the South African Abseil by those representatives present as none of the countries taking part had seen the method before. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「South African Abseil」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
