     On August 15th, in the women's individual all-around final of gymnastics of the Beijing 2008 Olympic

Games, Chusovitina is a shining star although she failed to win a medal eventually.

     When 33-year-old Oxana Chusovitina competes in her fifth Olympics (Beijing Olympics), she is twice

the age of most of her competitors. In addition, she has also competed in ten World Championships, three

Asian Games and three Goodwill Games. Chusovitina holds the record for the most individual World

Championships medals on a single event. She won an Olympic team gold medal as a 17-year-old in 1992.

Since then she has won a record of eight world titles.

     Her long career owes something to fate. In 2002, when her son Alisher, now aged nine, was diagnosed

with leukemia (白血病), she moved to Germany so that he could get the best possible treatment. To help in

those difficult times she kept up her training. It has paid off. But saving Alisher's life is not her only motivation.

As she recently told German media, "There is nothing in the world I enjoy more than gymnastics."

     Chusovitina was born on June 19, 1975 in Uzbek USSR. She was formerly a citizen of, and a competitor

for, the former Soviet Union (before 1993) and Uzbekistan (1993-2006). She has competed for Germany

since 2006. By the year of 2008, Chusovitina's career in gymnastics had been twenty years.

     She is one of only a handful of women to return to high-level gymnastics and international competition

after becoming a mother. Chusovitina is remarkable in her ability to remain competitive for so many years,

often in the face of great difficulty, and has been considered as a role model and an inspiration by many people

in the gymnastics community.
