蹦极是目前年轻人当中十分流行的一项极限运动,需要一定的冒险精神。蹦极时,跳跃者要站在一定的高度上,用一端固定的长长的橡皮条绑在踝关节处,然后两臂伸开,双腿并拢,头朝下跳下去。由于橡皮条很长,足以使跳跃者在空中享受几秒钟自由落体运动的乐趣。当人体落到离地面一定距离时,橡皮绳被拉开、绷紧。当到达最低点时,人随着橡皮绳向上反弹,然后又再次落下,这样反复多次直到橡皮绳的弹性消失为止,这就是蹦极的全过程。

Bungee jumping, the hopper to stand at a certain height, with one end of the fixed long rubber strap tied to the ankle joints, and then arms outstretched, legs close together, head down to jump down. Due to the long rubber band, enough for the hopper to enjoy a few seconds of free-fall in the air. When the human body falls a certain distance from the ground, the rubber cord is pulled open and tightened. When it reaches the lowest point, the person bounces up with the rubber band and falls again. This is repeated several times until the elasticity of the rubber cord disappears. This is the whole process of bungee jumping.
