Prior to 1981, the minimum required age to compete in senior events sanctioned by the FIG was 14. The earliest champions in women's gymnastics tended to be in their 20s; most had studied ballet for years before entering the sport. Hungarian gymnast Ágnes Keleti won individual gold medals at the age of 35 at the 1956 Olympics. Larisa Latynina, the first great Soviet gymnast, won her first Olympic all-around medal at the age of 21, her second at 25 and her third at 29; she became the 1958 World Champion while pregnant with her daughter. Czech gymnast Věra Čáslavská, who followed Latynina to become a two-time Olympic all-around champion, was 22 before she started winning gold medals at the highest level of the sport, and won her final Olympic all-around title at the age of 26.
