"We practically have no chance to win the title," Russia captain Shamil Tarpischev said. "We are going not to win but to warm up our young players."
Maria Kirilenko, Anastasia Pavlyuchenkova and Elena Vesnina, who led Russia to its sixth final in 10 years, all preferred to appear in the Tournament of Champions in Bulgaria opening next Tuesday.
Two-time Grand Slam champion Svetlana Kuznetsova refused to play for personal reasons, while No. 3-ranked Maria Sharapova has ruled herself out for the rest of the year with a shoulder injury.
Tarpischev told Russian daily Sport-Express he cannot blame the players for their refusal to play.
"We are not football or ice hockey players. Even if we win in Cagliari, no one will pay much attention to our victory," he said.
Italy has won the title three times. Russia is a four-time champion and beat Italy in the 2007 final.
