Title: Methods of weight manipulation in women in combat sports in the Czech Republic Objectives: The aim of this study was to find out what methods of RWL are most frequently used by women in combat sports in the Czech Republic. Methods: We used a purpose-built online questionnaire to collect the necessary data, which we distributed through social media such as Facebook and Instagram. We then processed the data in Jamovi, where we used descriptive statistics. Results: Our results showed that a total of 96,2 % of the participants in our study who do martial arts in the Czech Republic practice RWL. We also found that female martial artists start losing weight at an average age of 17 years (SD=4,45) and their average weight loss is 2,56 kg (SD=2,50). As some of the most common methods of RWL, we observed a reduction in caloric intake of 52,6 % and fluid restriction of 42,1 %.

Title: Methods of rapid weight loss used by Czech combat sports athletes. Objectives: The aim of this research project was to determine the prevalence of rapid weight loss (RWL) methods and their specific forms in Czech combat sports athletes. Methods: To determine the use of the methods of rapid weight loss (RWL) we used a purpose- built online questionnaire that was distributed via social media. This research project was open to men and women over the age of 18 who were actively competing in combat sports in the Czech Republic. Although only certain data from men were used for this project. Results: We found, that 94,7 % of participants reduce their body weight before competitions. This reduction then averages 5.33 kg (SD = 3.42) of body weight. The most commonly used methods to reduce weight across combat sports athletes included reducing energy intake (59,1 %), water loading (38,1 %), restricting fluid intake (33,3 %) and more conditioning (28,6 %).
