Kajsa Margareta Bergqvist (Swedish pronunciation: [ˈkajːsa ˈbærːjˌkvɪst]; born 12 October 1976) is a Swedish former high jumper. She won one bronze medal in the Olympic Games, one gold and two bronze medals in the World Championships in Athletics and one gold and one bronze in the European Championships. Her personal outdoor record of 2.06 m, set in Germany in 2003, is also a Swedish record. Her indoor record of 2.08 m, set at the Hochsprung mit Musik meeting in 2006, is still the standing world indoor record.

Bergqvist was born up in Sollentuna Municipality in Stockholm County. Her interest in sport began when she was 6 years old and tried sports such as football, volleyball, badminton, swimming and cross-country skiing, none of which was able to keep her interest.

When she was 10 years old, she was persuaded by her big brother, Anders, to compete in Rösjöloppet, a long-distance track event. After that event, she began to try out several athletic events.

Bergqvist continued to train in several athletic events until she was 15 years old, when a new coach, Bengt Jönsson, came to her club, Turebergs FK. Soon after his arrival, he and Bergqvist chose to concentrate on the event that was her best, high jump.

Lolo Jones was born on August 5, 1982. In her youth, Lori "Lolo" Jones had a series of obstacles to overcome. Jones attended eight schools in eight years while her single mother, Lori, often held down two jobs to support her family of six. Lolo's father spent most of her childhood in the Air Force or later in state prison. In third grade, the Jones family settled in the basement of a Des Moines Salvation Army church. During the summer when day camps were offered at the church, Lolo would wake up early to avoid being teased by other kids if they found out she was living in the basement.
