Discrimination in professional sports is still present today, despite the great efforts of sports organisations and individuals in combating it. Discrimination, on any grounds, undermines the positive values that sports promotes. In today´s modern age where information is readily available, it is truly amazing that the topic is the subject of serious debate. Upbringing and education has never been available in the history of mankind as it is today, and with equal opportunities for most young people for education, however, there are still difficulties and problems for part of the population in the world. The aim of this paper is to analyze the problem of discrimination in professional sports based on relevant scientific and professional literature. The first part of the paper explains the broader concepts of culture and interculturalism, as well as the concept of discrimination and the problems of dicrimination in top sports today. The central part describes in detail gender and gender discrimination and racial dicrimination. Examples of gender discrimination are given, as well as examples of racism in order to gain better insight into the issue of working with direct examples from top sports. The final part of the paper explains the ways and preventive/educational programs of combating discrimination and raising awareness of this serious problem today in the 21st century. A progressive and modern democratic society that wants to have a foundation based on just, moral principles for the benefit of all people regardless of diversity, and especially top athletes and their fans should openly discuss the problem of discrimination.
