U.S. Olympian Carmelita Jeter knows the value of practice and persistence. In 2009 Carmelita Jeter ran the 100-meter dash in just 10.67 seconds, making her the fastest woman alive and the second fastest woman in recorded history after the late Florence Griffith-Joyner. While she might be known as the 'Fastest Woman Alive' now, it wasn't always the case.

Having failed during the semi-finals at the 2008 trials for Beijing, her latest victory during the women’s 100-meter title at the U.S. Olympic track and field trial  was the culmination of a determined four years, a lot of training and a computer simulation software developed by Ralph Mann, USA Track and Field’s Sprint and Hurdle Biomechanist.

Using the software, Jeter is able to see a visualization of her perfected form via a stick-figure simulation to help her figure out movements that will help reduce time, drag and vertical momentum.
