时隔四年，两届奥运会，为什么刘翔身上会发生一模一样的事？职业生涯从来没有摔栏的刘翔，为什么会在第一个栏架就猝然摔倒？为什么刘翔的跟腱伤在经过了漫长的、耗费巨资的治疗后，一度说“痊愈”，临到奥运会前又诡异地复发？这一切，都像是悬念大师希区柯克电影中的一个谜。

After four years，Two Olympic Games，Why liu xiang can happen to the same thing？Career never fell column of liu xiang，Why does the meeting in the first hurdle is abrupt fall？Why liu xiang's Achilles tendon injury after long、Expensive after treatment，Once said“recovery”，Upon before the Olympics and is eerily recurrence？All this，All such as suspense master Hitchcock film of a mystery。

　　“八步改七步”种下祸根 师徒为此早有分歧 “Eight steps to seven steps”Under a curse teacher and pupil to early have differences

　　经过了2008北京奥运的退赛，2011年刘翔复出之后有一个重大改变，那就是将原来的“八步赶蝉”改成了“鬼脚七”——这意味着刘翔要把起跑到第一个栏之间的8步上栏变成7步，减少这一小步，看似简单，但是对于已经使用8步上栏十余年之久的刘翔来说，这绝不仅仅只是一次技术的革新，更是一次巨大的冒险。

After the 2008 Beijing Olympic Games out of the race，2011 years after liu xiang return there is a significant change，That is the original“Eight steps cast cicada”Changed to“Ghost seven feet”- this means that liu xiang to start to the first column of the eight steps between the column into seven steps，To reduce this one small step，Looks be like simple，But to have used eight steps on the field for more than 10 years for liu xiang，It's not just a technical innovation，Is a great adventure。

　　其实早有消息称，在“八步改七步”的问题上，刘翔与师傅孙海平存在分歧。刘翔1米89的身高不够高也成了他七步上栏不被看好的原因，由于七步上栏对运动员要求极高，而且面临着受伤的风险。因此事实上，在刘翔之前只有4人采用过七步上栏的技术，世界上第1个采用七步上栏的是芬兰选手布吕加雷，他因2米04的身高成为首位尝试八改七之人，美国人希克斯是第二个采用七步上栏的队员，不过身高1米87的他随后出现伤病，没能取得任何辉煌成绩，他也由此成为8改7失败的典型。随后身高1米92的古巴天才罗伯斯以及身高1米88的美国飞人奥利弗也先后由八改七，虽然奥利弗身高不如刘翔，但美国人格外健硕的身材成了助他成功的关键，刘翔就曾戏言奥利弗的手比他的腿还粗。

In fact as early as a source says，in“Eight steps to seven steps”On the question of，Liu xiang and master sun haiping has differences exist。Liu xiang 1 meter 89 height is not high also became him seven steps on the field is not optimistic about the reason，Due to the seven steps to the bar athletes demand is extremely high，And faced with the risk of injury。Hence the fact that，Liu xiang in only four people before the seven steps on the field technology，The world first using seven steps on the field is LvJiaLei Finnish player cloth，He was the height 2 meters became the first try to eight to seven people，Americans hicks is the second using seven steps on the field players，But the height 1 meter 87 he followed by injuries，Can't make any brilliant achievements，He also will be 8 to 7 typical failure。Then height 1 meter 92 Cuba's dayron robles genius and height 1 meter 88 American air oliver also has the eight to seven，Although oliver height as liu xiang，But americans particularly strong figure became to help him the key to success，Liu xiang had jeu oliver hand than his leg is coarse。

　　刘翔原本就有伤在身，右腿跟腱一直存在严重的隐患，在这种情况下，他为何非得冒着巨大的风险，“八步改七步”？现在看来，恐怕还是来自成绩的巨大压力让刘翔及其团队下定决心“冒险”——成者王侯败者寇，竞技体育本就残酷，如果再加入巨大的商业利益因素，单纯的个人，在“团队利益”面前便会显得渺小而无助，即使这个人，是刘翔。

Liu xiang was injured thierry，The right leg Achilles tendon there has been serious hidden trouble，In this case，Why he had to take a great risk，“Eight steps to seven steps”？Now it seems，I'm afraid or result from the huge pressure let liu xiang and the team are determined“adventure”- a winner raja loser Curtis，The cruelty of competitive sports，If add huge commercial interests factors，Pure personal，in“Team interests”Will appear before the small and helpless，Even though the man，Is liu xiang。

　　“豪赌”金牌 盲目加量 “德国模拟练”压垮跟腱 “gamble”The gold medal blind dosage “Germany simulation practice”Overriding Achilles tendon

　　去年正式复出之后，刘翔一直顺风顺水，正因如此，国人的胃口又一次被高高地吊了起来，即便此前，我们一起见证过刘翔在2008北京奥运会上的退赛。理想很丰满，现实太骨感，刘翔在伦敦选择了与在北京不同的方式，但结果却是相同的，

Last year after officially return，Liu xiang has been automatics，Because of this，The appetite of people once again be high hanging up，Even after，Together we have witnessed the liu xiang in the 2008 Beijing Olympic Games out of the race。Ideal are very plentiful，Reality too bone，Liu xiang in London chose different ways and in Beijing，But the result is the same，

　　国家体育总局田径运动管理中心副主任冯树勇表示“刘翔的跟腱伤势一直就没有完全痊愈”，“每次跑完之后都有比较大的反应，因为原来很多比赛都是一枪决胜负，没有很快很近的后续比赛，所以有逐渐的恢复”，伦敦奥运会要跑“三枪”，冯树勇直言“奥运会这种三枪的赛制，没有预料跟腱会有断裂的情况发生”。他还透露“在适应奥运赛制的过程中，刘翔的脚伤反应有所加重”。

State general administration of sport track and field sports management center, deputy director of the FengShuYong said“Liu xiang of the Achilles tendon injury has not fully recovered”，“Every time after running have larger reaction，Because so many games are a shot，No soon close follow-up game，So a gradual recovery”，The London Olympic Games to run“3 guns”，FengShuYong the truth“The Olympic Games this three gun format，Did not expect Achilles tendon will have broken happens”。He also revealed“To adapt to the Olympics in the process of the system，Liu xiang's foot reaction increased”。

　　解读冯树勇的话，我们似乎可以得出这样的结论，如果伦敦奥运会仍然是一枪决胜负，刘翔应该可以顺利完成比赛，甚至有望取得好成绩，毕竟他在复出之后成绩一直非常稳定；那么为什么刘翔却在预赛即“第一枪”时就出事了呢？这是因为刘翔在“适应奥运赛制”的过程中，“脚伤反应有所加重”。而从时间、地点上分析，刘翔应该是在德国“秘密适应奥运赛制”的，伦敦的事儿只是表象，真正的问题还是出在德国。

Reading FengShuYong words，It seems that we can draw such a conclusion，If the London Olympic Games is still a shot，Liu xiang should be able to smooth finished the race，Even is expected to get good grades，After all, he in upon his return performance has been very stable；So why liu xiang was preliminary namely“The first gun”When he had an accident?？This is because in liu xiang“Adapt to the Olympic format”process，“Foot reaction increased”。And from the time、Site analysis，Liu xiang should be in Germany“The secret to adapt to the Olympic format”of，London's business just representation，The real problem or out in Germany。

　　在德国期间，刘翔是如何“适应奥运赛制”的？有人分析称，那只能是严格按照伦敦奥运会的标准、时间间隔、强度，“跑三枪”。让刘翔在德国练习“三枪”，不仅可以帮助刘翔适应赛程、赛制，更重要的还能摸摸底儿，搞清楚刘翔到底能跑出什么样的成绩——也许，正是这样的“摸底”念头，让刘翔原本就脆弱的跟腱，彻底垮了，否则，按照逻辑，刘翔应该轻松跑完预赛晋级半决赛，他应该是在半决赛之前由于恢复时间过短而“出事”，而不是在预赛中便“过早出事儿”。

In Germany during the，Liu xiang is how to“Adapt to the Olympic format”of？Someone analysis says，That can only be in strict accordance with the London Olympic standard、Time interval、strength，“Run 3 guns”。Let liu xiang practice in Germany“3 guns”，Not only can help liu xiang to adapt to the schedule、format，More important still can touch bottom，To clear up the liu xiang can run out what kind of result, perhaps，It is such“Touch bottom”idea，Let liu xiang was fragile Achilles tendon，Completely collapsed，otherwise，According to the logic，Liu xiang should easily run the preliminary to the semi-final，He should be in the semi-finals because before recovery time too short and“accident”，Not at the trials will“Premature out of business”。

　　此前，刘翔的教练孙海平在接受采访时就透露，刘翔在德国的训练量有了大幅度的提高。而这次“豪赌”的“筹码”，正是刘翔的伤脚。

after，Liu's coach sun haiping has said in an interview is，Liu xiang in the German training had the large scale enhancement。And the“gamble”of“chip”，It is liu xiang's foot injury。

　　对金牌的过度渴望，导致刘翔的团队高估了刘翔伤脚的承受能力，结果加量的训练，使得刘翔的脚伤复发，从而满盘皆输。

Excessive desire for the gold medal，Lead to liu xiang team overvalued liu xiang's broken foot to bear ability，The results add amount of training，That liu xiang's foot recurrence，Thus one false move may lose the game。

　　阿喀琉斯之踵，是谁制造 医疗、教练团队集体失职 Achilles heel，Who is manufacturing medical、The coach team collective dereliction of duty

　　没有人怀疑刘翔确实是不能跑了，所以他从运动员通道突然转身，用一条没有受伤的腿完成了剩余的110米跑道，令人钦佩。

No one doubts that liu xiang is really can't run，So he suddenly turned from athletes channel，Use a without the injured leg finished the rest of the 110 m runway，admirable。

　　但刘翔的团队在干什么？在过去的整整4年，一次次到国外治疗、休养，中国田径的大部分精力似乎都在维护刘翔的右腿跟腱。中国体育史上，没有一名运动员，享受过这种待遇。但即便如此，曾经被孙海平教练亲口宣布“已经完全好了”的跟腱，又在关键时刻诡异地“旧伤复发”，他的医疗团队究竟在干什么？

But liu xiang team doing？In the past for 4 years，After treatment to foreign countries、rest，Most of the Chinese track and field energy seems to be in the maintenance of liu xiang right leg Achilles tendon。China's sporting history，Not an athlete，Enjoy this treatment。But even so，Coach sun haiping has ever been announced the mouth“Was completely cured”Of Achilles tendon，And in the critical moment is eerily“Old injury has a relapse”，His medical team actually doing？

　　如果刘翔的伤真的没有好，似乎也没有人逼着他急于复出，如果刘翔真的是因为过多的比赛而促使旧伤复发，那么他背后的科研团队和教练们，又究竟是如何估算和预判的？

If liu xiang's injury really there is no good，Nor did anyone seem to make he was anxious to return，If liu xiang really because too much competition, and make the old injury has a relapse，Then he behind the scientific research team and coaches，And what exactly is how to estimate and anticipation？

　　可以说，刘翔的此次旧伤复发，是包括医疗、科研、教练等在内的刘翔团队的集体工作失职。(殷小平 刁勇 黄启元 陈婧)
