The aim of this thesis is to determine the connection between the achieved success at the Olympic Games and the development of the economy (GDP per capita), area of the country and its population size, and in consideration of that whether the countries are at the top or bottom of the achieved sports success table, analyzed separately at the summer and winter Olympic Games from 2000 to 2020. In this way, it will be determined which predictor variables have the most significant impact on a positive outcome, victory in the Olympic Games. The sample included in the analysis consists of two groups of countries. The first group includes the ten most prosperous countries in particular Olympics, while the second group consists of countries with only one medal. Indicators of development or diversity of countries are an area of a country, population, amount of GDP, or PPP (purchasing power parity). The results showed a statistically significant correlation for the GDP variable at all measured Summer Olympics except Tokyo 2020. The area variable shows a statistically significant correlation at the older Olympic Games from 2000 to 2008, while the population variable is more important in newer editions of the 2008 Games up to 2020. No results have been obtained for countries with one medal won on which conclusions can be drawn. No correlation was found between the measured variables and the number of medals won at the Winter Olympics. Although most research confirms the country's economic power as an important predictor of success at the Olympics, without the inclusion of other variables, we cannot fully explain success at the Olympics.
