[1] Sanita Buliņa made her first appearances in international biathlon competitions at the 2018 Youth World Championships and also competed in the IBU Junior Cup during the following winter.

With the start of the 2019/20 season, the Latvian made her IBU Cup debut and participated throughout the entire winter, though she did not achieve any top-60 finishes.

In the 2020/21 season, Buliņa was part of the World Cup team from the start and immediately achieved a respectable 64th place in the sprint in Hochfilzen.

Motivated by this result, Buliņa won medals in all three events at the Youth Summer Biathlon World Championships in 2021, despite making several shooting mistakes.

At the beginning of the 2023/24 season, Buliņa earned World Cup points for the first time in nearly three years, finishing 33rd in the sprint and 30th in the pursuit in Östersund.
