The name comes from the pumping motion used by the cyclist's upper and lower body as they ride around the track. The purpose of a pump track is to use this pumping motion to maintain speed around the track without pedaling.〔(【引用サイトリンク】 title=What is a pump track? )〕〔(【引用サイトリンク】 title=Pumpin’: An Introduction to the World of Pump Tracks )〕 == History == The origins of the pump track are BMX trails of the 1970s and 1980s. Australian downhill racers began creating the new era pump tracks around 2002. The first new era pump track in the United States was built in 2004 at The Fix Bike Shop in Boulder, Colorado, by professional downhill bicyclist Steve Wentz.〔 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「Pump track」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.
