Volleyball is a sport played by two teams of six players separated by a net. The objective is for each team to send the ball over the net and ground it on the opposing side before it can be returned. There are six basic skills in volleyball: serve, pass, set, attack, block, and dig. Players also specialize in different positions including setter, opposite hitter, outside hitter, middle hitter, and libero. Brazil has been very successful in international volleyball competitions, with their women's team winning gold in volleyball at the 2008 Beijing Olympics and their men's team winning gold in 1992 and 2004.
