How quickly things can change.

A year ago, sprinter Chisato Fukushima was a relatively unknown figure on the international stage. She now has the valuable experience of Olympic competition to draw lessons from and a renewed desire for success against the world's best.

Representing Japan in the women's 100- and 200-meter races and the 4×100-meter relay, Fukushima brings her speed and athleticism to Berlin for the 2009 IAAF World Athletics Championships. Her first event, the 100, begins on Sunday.
