With her victory in Tokyo, Lasitskene became the fourth female high jumper in history (after Stefka Kostadinova, Heike Henkel & Anna Chicherova) to win gold at both the Olympic Games and the World Championships.

[5][6] In the inaugural 2010 Summer Youth Olympics, Lasitskene won a gold medal in the girls' high jump with a clearance of 1.89 m, ahead of Alessia Trost.

However, she was barred from competing when the CAS upheld their decision to ban the Russian Track and Field Federation from the Games for systematic doping.

She followed up her strong performances in the Diamond League competitions by defending her world title later in London on 12 August 2017 with a height of 2.03 m. Lasitskene wrote on Instagram regarding Russia's ban from international athletics that she was "totally not surprised about this outcome" and planned to compete under a neutral flag.
