The 34-year-old centre back is in his second spell at Pittodrie, and feels he has proved that he is over the injuries that blighted his time away from Aberdeen.
"I've always said the day I don't feel up for the rigours of the SPL, I'll stop there and then but right now," he told RedWeb. "I'm as fit as I have been and I'm really looking forward to at least another year playing.
"I started my career at Aberdeen and it's fitting that I'll finish my playing career here as well."
Aberdeen chief executive Duncan Fraser added: "Russell's influence both on and off the park is absolutely immense and he is a club captain in the true sense of the word.
"He has always said he wants to carry on playing for as long as he feels able to do so and everyone at the club is delighted for him."
