Introduction: One of the most frequently injured joints in the human body is the knee joint. In knee injuries, one of the most common injuries is the anterior crucial ligament injury. In the recent times, therefore, a number of prevention programs have been developed to reduce the incidence of anterior crucial ligament injuries. These programs includes exercises for strength, agility, proprioception, stretching and plyometric exercises. Plyometric exercise is commonly used in preventive programs, as it improves the biomechanics, neuromuscular control of the joint and consequently, the stability of the joint. Because of all of the above, it also helps to reduce injuries. Purpose: The purpose of this diploma work was to determine the effectiveness of prevention programs that include plyometric exercises in reducing the incidence of anterior crucial ligament injuries in sport, based on a review of the professional and scientific literature. Methods: Descriptive methods were used with review and analysis of peer-reviewed and scientific literature. The literature was searched in the PubMed and ResearchGate databases. The following keywords were used: Preventive programme, plyometric exercise, anterior crucial ligament. Results: This diploma work included 8 studies investigating the effectiveness of prevention programs to reduce the number of anterior crucial ligament injuries in sports. In all studies, there were fewer anterior crucial ligament injuries in the intervention group than in the control group. However, only four studies showed that these differences were statistically significant. Discussion and
conclusion: Based on the results, we can conclude that preventive programs that include plyometric exercise are effective in reducing anterior crucial ligament injuries in sports. For maximum effect, it is important that the exercises are adapted to the individual's sport, are
appropriately intensified and that the program is carried out regularly throughout the season. In the future research, it would be necessary to investigate how individual components of the program actually affect the reduction of anterior crucial ligament injury, as we currently have no way of knowing whether one component dominates over the other.
