Every athlete battles mental barriers. But this Olympian must defeat physical barriers too: all ten of them!


  Hi, I'm Dr Greg Wells. Hurdlers are incredible multi-taskers. They have to be. Taking off like they've been shot from a cannon 1, they must somehow maintain enough control to soar, smoothly 2, over barriers about a metre high, in rapid succession.


  So, how do they pull it off? When most of us run, our femur moves through a small range of motion in the hip 3 socket 4 -and in just one direction. But hurdlers train to move their femurs differently: they have twice the range of motion, and rotate in a circle at the same time!


  The secret is a special stomach muscle called the psoas. It runs from your thigh 5 bone, through your stomach, and up your lower back. Hurdlers lengthen 6 and strengthen their psoas muscle. That lets them whip their trail leg through the entire range of motion with incredible speed.


  The average person can run 7-10 km/h, but the unique combination of strength and flexibility 7 enables an Olympic hurdler to hit up to 30! The fusion 8 of hip motion and muscle recoil 9... That's how you leap to gold!


  中文字幕:


  每位运动员都要克服心理障碍。而这位奥运选手还必须克服实际障碍,共有十个之多。


  我是维尔斯博士。跨栏选手是神奇的多面手,他们必须做到。他们起跑犹如炮弹,但又必须保持足够控制力,才能顺畅地越过约一米高的障碍物,一个接一个。


  他们是怎么做到的呢?我们跑步时,大腿的股骨在髋臼内作小幅度的运动,而且只朝一个方向。但跨栏选手股骨的运动有所不同,活动幅度达常人两倍,同时还可以打圆圈。


  秘密在于腹部一块叫腰肌的特殊肌肉。腰肌从大腿骨经腹部连到下背部。跨栏选手把腰肌练得更长更强,让他们的跟进腿能以惊人速度,跨出大幅度动作。


  一般人跑速是每小时7到10公里,而奥运跨栏选手结合劲力和灵活度,可以达到时速30公里。髋部运动加上肌肉回弹,就是夺金之道!
