At the 2004 Summer Olympics in Athens, women appeared in wrestling for the first time competing in the freestyle weight classes of 48 kg, 55 kg, 63 kg and 72 kg. Women also competed in the sabre discipline of fencing for the first time, with Mariel Zagunis of the USA winning gold. In 2004, women from Afghanistan competed at the Olympics for the first time in their history after the nation was banned from Sydney 2000 by the IOC due to the Taliban government's opposition to women in sports. At the 2006 Winter Olympics in Turin, the programme remained unchanged. At the 2008 Summer Olympics in Beijing, a few new events were added. BMX cycling was held for the first time in 2008, debuting with the men's event. Women also competed in the 3000 m steeplechase and the 10 kilometre marathon swim for the first time. Baseball and boxing remained the only sports not open to women at these Games.
