英国《自然》期刊揭露叶诗文奥运造假

(CONTINUED)
How would performance be used to nab dopers?

Anti-doping authorities need a better way of flagging anomalous performances or patterns of results, says Schumacher. To do this, sports scientists need to create databases that — sport by sport and event by event — record how athletes improve with age and experience. Longitudinal records of athletes’ performances would then be fed into statistical models to determine the likelihood that they ran or swam too fast, given their past results and the limits of human physiology.
The Olympic biathlon, a winter sport that combines cross-country skiing and target shooting, has dabbled in performance profiling. In a pilot project, scientists at the International Biathlon Union in Salzburg, Austria, and the University of Ferrara in Italy, developed a software program that retroactively analysed blood and performance data from 180 biathletes over six years to identify those most likely to have doped2. The biathlon federation now uses the software to target its athletes for drug testing.

Could an athlete then be disciplined simply for performing too well?

“That would be unfair,” says Tucker. “The final verdict is only ever going to be reached by testing. It has to be.” In recent years, cycling authorities have successfully prosecuted athletes for having anomalous blood profiles, even when banned substances such as EPO could not be found. But performance is too far removed from taking a banned substance and influenced by too many outside factors to convict someone of doping, Tucker says. “When we look at this young swimmer from China who breaks a world record, that’s not proof of anything. It asks a question or two.”

自然网站的新闻版与自然期刊是不同的概念，楼主哗众取宠了，更糟糕的是，早在你发帖之前，自然的主编已经道歉

（（道歉没有用，华人与狗不得如内道歉100年了，米国华人黑奴铁路工人也被道歉了，失去的声誉是无法弥补的。

200年后，华人种族歧视种族迫害还会存在。））

uzhuanzaouuuuuuuuuuuuuuuuuuuu

居然有这样的文章

黑TC的都没好下场

英国《自然》杂志不是已经道歉了吗！！
