The governing body for world track and field has said a ban on Russian athletes is being extended amid concerns that the country was "backsliding" on reforms to its anti-doping programs.

世界田径管理机构表示，由于担心俄罗斯在反兴奋剂项目的改革上出现“倒退”，对俄罗斯运动员的禁令被延长。

The International Association of Athletics Federations (IAAF) said on Sunday that Russia had another three months to demonstrate it was making progress in cleaning up drug-monitoring systems.

国际田径联合会周日表示，俄罗斯方面有三个月时间来证明其在清理兴奋剂监督系统方面取得进展。

If it doesn't, "clean" Russian athletes would be required to compete under a neutral, non-Russian flag at the world championships that begin in September in Qatar.

如果未能取得进展，未使用兴奋剂的俄罗斯运动员在今年9月卡塔尔世锦赛上就会被要求以中立、非俄罗斯身份参赛。

Rune Andersen, who heads the IAAF’s task force overseeing Russian compliance, said Russia had made older samples of athletes' tests available so that regulators could screen them for past offenses.

国际田径联合会负责监督俄罗斯合规的特别工作组负责人安德森（Rune Andersen）说，俄罗斯已经提供了运动员之前的测试样本，以便监管人员检查他们过去是否违规。
