"Some Russian officials threatened us, including my family, they wanted to silence us," said Jiri Hamza, who became the first vice-president of the International Biathlon Union (IBU) after the resignation of former IBU head Anders Besseberg.
"It was a tough period but I'm glad we didn't give up," he told the website of Czech broadsheet Lidove Noviny daily.
Besseberg and IBU general secretary Nicole Resch are facing accusations that they helped cover up Russian doping in the Winter Olympic sport combining cross-country skiing and shooting.
The IBU eventually stripped Russia of the championships.
Besseberg stepped down in April and was replaced by Swede Olle Dahlin in September.
Hamza said the IBU had a long way to go as it was still full of people happy with the "narrow-minded" Besseberg leadership.
"But we don't want to take any revenge -- we want a dialogue instead.
"That's the biggest change because over the past eight years the IBU has been managed by three people and the rest were mere pawns moved by Besseberg and his cronies."
