[1] In 2012, she began competing among seniors and was selected for the 2012 Summer Olympics, where her team was placed ninth.

[2] Individually she competed in the vault, uneven bars and floor exercise, but failed to reach the finals in the last two events.

Her first vault, officially named Chusovitina in the Code of Points but more commonly known as Rudi, had a good height and amplitude,[clarification needed] but excessive piking of the hips in the final phase led to an uncontrolled landing.

She won the vault competition at the Turnier der Meister World Cup in Cottbus, Germany.

In 2014 Janine participated in 2014 European Women's Artistic Gymnastics Championships and in vault finished 5th with a score of 14.416.
