老内说刘翔的身材与长腿跨栏者比过栏相对容易。

老内另外夸刘翔的平跑速度也是恰到好处。

总而言之，刘翔的身体条件和平跑速度都是恰到好处，再加上极好的过栏技术和心理素质，是他称霸高栏的充分必要条件。

不知满兄在学校时，记不记得田径队的跨栏教练顾老师的身材。就属于那一类的。

老内的原话是，

1.89m high, weighing 82kg, has "a long body frame but short legs" Therefore it is easier for him to NEGOTIATE his smaller legs over the hurdles,"unlie more leggy man like Arnold and Trammell."All this is done by having extremely glexible hips," conclude Nehemiah.

...But specifically what is tghe key to Liu Xiang's sucess as a hurdler?
"He is technically sound. His basic flat speed is not as good as the other guys which means that he can race the hurdles at his TOP speed without fear of going too fast. ... can just concentrate on his technique, cleaning the hurdles low."

"His opponents are much quicker flat sprinters but that speed is a DISADVANTAGE for them."

The big men have always to adjust their speed b/c they try to go too fast and by mid-race the hurdles start to come too quick on them for them to cope and hurdle cleanly ... they have to make continue adjustments to their speed ... Too much speed killed Arnold, Doucoure adn the rest yesterday."

By contrast, Liu xiang cna use his full velocity in a race, he doesn't have to make any adjustment and so can concetrate on staying low over the barriers." He has learnt to "shuffle perfectly" between the hurdles.

Howver, "add another half a yard in the space between the barriers" and the balance would go back in the favour of the men with faster flat speed. "They would be unstoppable."

(BTW，栏距是30FT， 9米14，起跑栏距是45英尺，13米72，栏高3尺6，1米06)。

另，你那篇5K雄文真是让人BFBX。我5K一直没什么长进。但游泳自从换了新泳裤后成绩提高。看来这装备还是有一定效益的：-)
