Lamine Diack, the former head of World Athletics, told a French court on Thursday he had slowed the handling of Russian doping cases between 2011 and 2013 to save a sponsorship deal with a Russian bank.
The 87-year-old said he had not sought to protect the athletes caught up in the scandal, some of whom later competed in the London 2012 Olympics, but to ensure the cases did not come to public attention all at once.
This, he said, would have caused a scandal.
Diack, once one of the most influential men in athletics, faces charges of corruption, money laundering and breach of trust. The charges carry a maximum sentence of 10 years in jail.
The former long-jumper has consistently denied wrongdoing.
"Who took the decision to spread out the [sanction procedures]? It was me," Diack told the court's three judges.
"Everyone said I was taking a risk, but it didn't stop us from quietly working on doping.
"When the Russian cases arose, we were going through a difficult moment financially. My duty was to make sure the IAAF got out of it."
Prosecutors allege Diack solicited bribes totalling €3.45m (£3.1m) from athletes suspected of doping to cover up test results and let them continue competing.
They also say Diack obtained $1.5m (£1.2m) of Russian funds while negotiating sponsorship and television rights to help finance Macky Sall's campaign for the 2012 Senegal presidential election, in exchange for slowing anti-doping procedures.
Diack told the court the Russian bank renewed its sponsorship contract worth $32m (£25m) in February 2013.
Earlier this week, Habib Cisse, Diack's former lawyer at the IAAF, renamed as World Athletics, told the court the IAAF could have survived financially without its Russian sponsors.
