          “极限运动”一词来源于英语中的“Extreme Sports”,大丰收一肖心水论牡是指一些近年流行的惊险刺激的另类体育运动项目(Alternative Sports Events),涉及陆上、空中、水上运动的各个领域,随着各种单项和综合极限运动会(Extreme Games)的发展,极限运动开始广为人知并逐渐成为全球青年喜爱的运动之一。极限运动往往以刺激和冒险著称,但不是所有的冒险活动起初就被归入极限运动,有些项目在初始阶段参与人数不多,随着项目的成熟和相关赛事的发展使一些如滑板、直排轮滑、特技单车、滑雪板、攀岩/冰、蹦极、高空跳伞、滑翔伞、冲浪、风浪板、尾波板、极限越野等运动形式成为大众熟悉的极限运动项目。
