Abstract
Background: Regular physical activity is crucial for the healthy development of children The aim of this study was to compare the physical fitness of children training in ju-jitsu with their non-training peers. Methods: The study involved 30 children aged 10-12, divided into two groups: 15 children training in ju-jitsu and 15 non-training children. A modified version of the EUROFIT test was conducted, including tests for hand and foot movement speed, flexibility, explosive strength, static strength, abdominal muscle strength, arm and chest strength, and running endurance. Results: The results indicate that children training in ju-jitsu show significantly better performance in most tests, suggesting that ju-jitsu training positively impacts the development of various aspects of physical fitness. An exception was static strength, where no significant differences were observed. Conclusion: The study highlights the benefits of regular ju-jitsu training for children, such as improved coordination, flexibility, explosive strength, abdominal muscle strength, arm and chest strength, and endurance. The conclusions can be useful for coaches, parents, and children interested in combat sports.
