The sports head coach in Russia Valentin Maslakov has stepped down.
On Tuesday, Russia’s anti-doping agency prohibited five race walkers.
Russian sport president Valentin Balakhnichev said: “Even though Maslakov has nothing to do with anti-doping policies of the sports team, he couldn’t stand by idly and chose to take responsibility for all those who he was in charge of.”
Maslakov, 70, had supervised the training of Russian team athletes since 2007.
His whole training career has spanned more than 40 years.
Sports’ governing body the IAAF says it’s worried in regards to the amount of doping instances that were Russian in the sport.
A total of 23 of the 37 sportsmen sanctioned under the IAAF’s biological passport programme since 2009 have been Russian.
2011 50km world champion Sergey Bakulin and London 2012 men’s 50km walk victor Sergey Kirdyapkin, girls’s 2008 Olympic 20km gold medallist Olga Kaniskina were prohibited for three years and two months with their cases.
Olympic 2008 victor Valery Borchin was prohibited for eight years and Vladimir Kanaykin for life.
Strange blood levels in the sportsmen’s biological passports were the reasons for the prohibitions.
