http://baike.baidu.com/subview/1839170/18346273.htm I think the word, 蹦极(bèngjí)跳(tiào) , is borrowed from the English word, 'bungee jumping', although it can also explain this activity/sport, meaning 'to jump from a pretty high place'. And '高空弹跳' is its Chinese name.

是一樣的 蹦極跳 是從英文 bungee 音譯的說法 高空彈跳 是中文翻譯的說法
