Field hockey player for Argentina Luciana Aymar is back for her third Olympics this year.

World Hockey Player of the Year in 2007 (as well as 2001, 2004 and 2005) as well as being team captain, the Argentinean team is going for the gold. In the past two Olympics, they have won silver and bronze.

An athlete since childhood, Aymar not only played but competed in tennis, roller skating, swimming and classical dancing. However, when she was 7 years old, her older sister Cintia introduced her to field hockey and it stuck.

The sisters even played together on the same team later in their lives.
