This research is part of the evaluative research typology. This type refers more to a research goal than to a specific method. It usually focuses on the evaluation or impact of a program or social intervention. The relationship between balance ability and the risk of sports injuries has been proven in many cases, but the relationship between balance ability and sports performance is less elucidated. The objective assessment of taekwondo and karate balance ability was achieved through the Y-Balance Platform, a dynamic foot or hand test that requires strength, flexibility, central control and proprioception. The purpose of this test is to maintain balance on a foot or hand, as far as possible with the other foot or hand in three different directions. The research was carried out on 16 students from the representative taekwondo and karate teams of the "Carol Davila" University of Medicine and Pharmacy (UMF), aged 19-26. The purpose of the research is to evaluate the ability to manifest dynamic balance in the two sports, as well as to compare this ability in the lower and upper limbs. The goal is to establish the balance performance level in taekwondo and karate athletes. Thus, in the right lower leg, the right upper and lower ante-medial limb, taekwondo athletes have achieved a better average compared to those who practice karate, with a confidence interval that does not contain 0.00, the difference being statistically significant at a two-tailed significance level of 5%.
