Nikitin was selected by the Brazilian Olympic Committee to compete for the host nation's archery squad at the 2016 Summer Olympics in Rio de Janeiro, shooting in both individual and team recurve tournaments. First, Nikitin discharged 609 points, 8 perfect tens, and 3 bull's eyes to take the fiftieth seed heading to the knockout draw from the classification round, along with the trio's cumulative score of 1,845. Sitting at eleventh in the team recurve, Nikitin and her compatriots Ane Marcelle dos Santos and Marina Canetta put up a gallant fight amid the loud applause of their parochial crowd, but bowed out of the opening round match to the Italians in straight sets 0–6. In the women's individual recurve, Nikitin was unable to overthrow North Korea's Kang Un-ju early in the opening round match that abruptly ended her Olympic debut in a severe 0–6 defeat.
