Gender based stereotype is an opinion based on which specific behaviours are only reserved for men or women. It is mainly argumented by biological differences between genders. People have nurtured such construct for centuries. This resulted in perceiving certain behaviours that go beyond the “socially acceptable” ones as a socially unacceptable. Manifestation of the aforementioned construct can often be seen in the area of sport. Discrimination against women is most often mentioned, however, in this paper we witness “reverse” gender discrimination, when men are being subjected to discriminatory practices. Artistic, ie synchronized swimming is a sport in which men are discriminated against, as in most aesthetic sports. The mentioned sport has been at the Olympics since 1984, however, men are not allowed to perform professionally at them. Although the situation has been slowly changing in favor of men since 2016, the problem is still relevant today. Therefore, this thesis has the goal of underlining the correlation between men being left out from the highest level of the competitive synchronised swimming and gender stereotypes in present modern society.
