中国反振奋剂中心8日发表声明，横暴敕令外洋检测机构（ITA）在巴黎奥运会时辰加大关于好意思国田径怒放员的振奋剂窥伺频率欧美av，重树公共怒放员对公说念竞赛的信心。

全文如下：

咱们留神到国表里干系媒体报说念了联系好意思国奥运田径新星埃里扬·奈顿振奋剂阳性案件的具体情况，同期好意思国反振奋剂机构（USADA）也针对该案件公开进行了回复。但咱们发现现在该案件仍存在诸多疑窦，举例USADA讲求东说念主公然声称，群勃龙在好意思国和天下其他地区齐是一种家喻户晓的牲口助长促进剂。为什么比年来公共发生了数以百计的群勃龙阳性，独一少量数好意思国怒放员基于USADA的访问成果和肉食物稠浊的主义逃走了禁赛处罚？为什么USADA莫得向好意思国怒放员给予任何干于肉食物中群勃龙稠浊的风险警示？

要是群勃龙在好意思国事一个常见的稠浊物资，中国反振奋剂中心教唆包括好意思国在内的列国怒放员，在好意思国查验比赛时密切关心该国的肉类食物稠浊问题，在好意思时辰加强振奋剂风险驻守，在意食用肉类成品。不然也许会像取得USADA坦护的好意思国拍浮怒放员菲尔普斯在近期采访中所提议的：要是振奋剂检测成果呈阳性，就遥远不可再插足比赛，一切齐限度了。

此外，奈顿被USADA片面“款待”也体现出另一种担忧：即好意思国田径样貌经常出现使用振奋剂的丑闻，且USADA在责罚振奋剂案件的式样上存在朝秦暮楚和诠释可疑的问题。据公开报说念，好意思国九枚奥运金牌得主卡尔·刘易斯曾承认，尽管在1988年汉城奥运会前三次检测均呈阳性，但最终照旧被“庙堂之量”，顺利代表了好意思国赶赴汉城。雅典奥运会百米冠军贾斯汀·加特林两度被查出阳性，按礼貌应当受到终生禁赛的处罚，但USADA却为其“发奋于解脱”，最终把禁赛期缩小为４年。2003年，好意思国旧金山巴尔科试验室曝出重创天下体坛的禁药丑闻，试验室讲求东说念主孔特供出的客户名单中包括百米女飞东说念主马里昂·琼斯、前须眉百米天下记载保合手者蒂姆·蒙哥马利、加特林等多名好意思国田径天下冠军，激励了外洋社会关于好意思国体育界奢靡振奋剂的担忧。吉尔·罗伯茨曾获里约奥运会4x400米悉力金牌，2017年他以和女友接吻所致振奋剂阳性为由，取得了USADA的“赦免”。然则，罗伯茨在2022年再次被查出服用犯禁药物，被处以禁赛16个月的处罚。2023年复出只是8个月，罗伯茨又因振奋剂阳性被处以8年禁赛。另外值得关心的是，本年4月，好意思国田径选手阿尔德里奇·拜利赛外窥伺呈雄激素受体调度剂奥司他林阳性，USADA认定是由于怒放员使用的氯丁橡胶大腿压缩袖受到了稠浊。干系事实标明，奥司他林并不是一种常见的稠浊物资。

鉴于好意思国田径限制树大根深的种种“裂缝”，以及USADA多次置步和谐圭臬于不顾，咱们有原理怀疑好意思国田径限制存在系统性使用振奋剂的问题，好意思国田径限制的振奋剂阳性事件值得合手续彻查和关心。正如WADA主席班卡所强调的：“天下各地功令机构齐已告诉WADA，好意思国事一个销售和分销擢升收成药物的浩荡阛阓。”又正如天下反振奋剂机构在近期发表的声明中提到，在东京奥运会赛前的一年中，31%的好意思国怒放员莫得取得充分的振奋剂检测。基于以上情况，咱们横暴敕令外洋检测机构（ITA）在巴黎奥运会时辰加大关于好意思国田径怒放员的振奋剂窥伺频率，同期横暴提议田径诚信委员会（AIU）加强关于好意思国田径怒放项蓄意反振奋剂监管，注重严查其怒放员振奋剂问题隐患，切实真贵列国干净怒放员的正当权利，重树公共怒放员对公说念竞赛的信心。

Intensify Testing on U.S. Athletics, and Rebuild Global Trust In Fair Play

China Anti-Doping Agency (CHINADA) noticed that the specifics of the U.S. Olympic sprinting star Erriyon Knighton’s positive test have been widely reported by media at home and abroad, following which the United Stated Anti-Doping Agency (USADA) made a public statement on the case. However, there are still a number of question marks surrounding the case. One example is that the USADA CEO said blatantly that “trenbolone is a well-known livestock enhancer in the U.S. and other parts of the world”. Now that hundreds of positive tests for trenbolone have taken place in recent years worldwide, why is it that only a very small number of U.S. athletes have escaped sanctions based on USADA’s investigation findings and claims of meat contamination? Why hasn’t USADA ever warned American athletes about the risk of contamination of trenbolone in meat?

If trenbolone is indeed a common contaminant in the United States, CHINADA would like to remind athletes from all over the world, including American athletes, to pay close attention to the meat contamination problem in the country when training and competing there, to strengthen doping risk prevention measures, and to eat meat products with caution. Otherwise, as the American swimmer Michael Phelps—under the wing of USADA—suggested in a recent interview, “if you test positive, you should never be allowed to come back and compete again, cut and dry”.

In addition, the fact that Knighton was unilaterally exonerated by USADA also reflects another concern: doping scandals have been too frequently seen on U.S. athletics, and USADA’s handling of these doping case has been inconsistent and questionable. According to public available information, Carl Lewis, the nine-time U.S. Olympic gold medalist, once acknowledged that despite testing positive three times before the 1988 Seoul Olympics, he was eventually “let off the hook” and represented the United States in Seoul. The Olympic 100m champion Justin Gatlin, who failed two doping tests and should have been banned for life according to relevant rules, was finally given a four-year period of ineligibility after USADA’s exculpatory efforts. In 2003, the a shocking doping scandal that hit the sports world exploded from The Bay Area Laboratory Co-operative (BALCO) in San Francisco, whose founder Conte provided a list of professional athletes buying their performance-enhancing drugs, including Marion Jones, the women’s 100-meter sprinting giant, Tim Montgomery, former world record holder for men’s 100-meter, Gatlin as mentioned above, and many other world champions in athletics. The BALCO scandal has triggered widespread concerns from the international community about doping in the U.S. sports field. Gil Roberts, once part of the U.S. 4x400 relay team that won gold at the 2016 Rio Olympics, was cleared by USADA in 2017 by claiming that his positive test was caused by kissing of his girlfriend. However, Roberts was found to have taken a banned substance again in 2022 and was given a 16-month ineligibility. Just eight months after his return in 2023, Roberts was again given an eight-year eligibility for a failing test. It is also worth noting that this April, the American track and field athlete Aldrich Bailey tested positive for ostarine, an androgen receptor modulator, during an out-of-competition test. It was then decided by USADA that the positive test was due to contaminated neoprene hamstring sleeves used by the athletes. However, ostarine is not a common contaminant, as facts show.

Given the deep-rooted stains in the U.S. athletics and USADA’s repeated disregard for procedures and standards, there is reason to suspect that there is a systemic doping problem in track and field in the United States and the positive cases therein deserve continuous investigation and attention. As pointed out by the President of the World Anti-Doping Agency (WADA), Mr. Witold Bańka, data collected in project involving law enforcement agencies and National Anti-Doping Organizations (NADOs) in Europe revealed that the U.S. is one of the world’s largest markets for illicit steroids and performance-enhancing drugs. Also pointed out by WADA in a recent statement, 31% of American athletes were not sufficiently tested in the 12 month-period prior to the Tokyo Games. In light of the above, we strongly call on the International Testing Agency (ITA) to intensify testing on the U.S. track and field athletes. We also strongly recommend that the Athletics Integrity Unit (AIU) strengthen anti-doping supervision of the U.S. track and field, prevent the doping risks and strictly investigate relevant cases欧美av, in an endeavor to truly protect the legitimate rights and interests of the cleans athletes around the world, and to rebuild the trust of global athletes in fair play.
