INTRODUCTION: Balance is the ability to maintain the center of gravity of the body above the base of the support. In order to successfully maintain and maintain balance, the central nervous system processes a series of information on an unconscious level which it manages through neuromuscular control. The aim of this paper is to determine whether there are differences in the balance between younger people who are actively involved in boxing and younger people who are actively involved in judo. The specific objectives of the study are: to measure whether there is a difference in maintaining balance on the dominant and non-dominant leg in both groups and whether the history of injury / injury of the lower extremities has an impact on the balance in both groups. MATERIALS AND METHODS: The study of balance differences was conducted on 30 persons / subjects. One group consists of 15 people who are actively involved in and train boxing, and the other group includes 15 people who are actively involved in and train in judo. All respondents are male between the ages of 18 and 33 years. Balance measurements for each subject were performed once, for 15 minutes. The research consists of two parts. In the first part, personal data about the respondent (age, height, weight) and the history of the injury, if they exist. The second part is a practical part in which the respondents had to step on the "Posturomed 2000" of the company "Bioswing" from Germany, size 60x60 cm with the corresponding software "Microswing 6" and keep balance on one leg for 10 seconds, according to the instructions of the examiners and computers. For the purpose of objectification, the procedure was performed 10 times on each leg, by randomly selecting the legs of the steps and maintaining balance. RESULTS: Balance in both groups is equal, without statistically significant differences. Differences between balance on the dominant and non-dominant leg are present only in boxers. Worse results have those athletes with a history of injury in both groups, but they are not statistically significant. CONCLUSION: Young judo and boxing athletes are not different in a large percentage in balance measurements on one leg.
