          “极限运动”一词来源于英语中的“Extreme Sports”,金靴赔率c罗优势加剧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。
