Lamine Diack, the former president of the world governing body for track and field, who was convicted last year of corruption for receiving bribes linked to a Russian doping scandal, died at his home on Friday in Senegal. He was 88.
His death was confirmed by his son, Papa Massata Diack.
Mr. Diack was for decades one of the most powerful men in sports as a member of the International Olympic Committee and as the head of the International Association of Athletics Federations, more commonly known by its initials, the I.A.A.F., which he headed from 1999 to 2015.
