The epidemiology of injury occurrence among adolescent basketball players in the City of Zadar was conducted on a sample of 89 respondents from three different clubs (Basketball Club Zadar, Basketball Club Opus Puntamika, and Basketball Club Diadora). The average age of the respondents was 15,78±1.30 years, ranging from 14 to 19 years. The average body weight of the respondents was 75,78±9.49 kg, while the average height was 186,51±8.24 cm. Accordingly, the body mass index was 21,78. A retrospective survey study on the epidemiology of injury occurrence in the 2023/2024 season was conducted on the respondents. The survey questionnaire, along with general participant information, examined the type, location, and frequency of injuries. Additionally, the conditions and situations of injuries, as well as training and competition loads, were examined. A total of 123 injuries were recorded, of which 76,2% were acute and 23,8% were overuse syndromes. The highest number of injuries occurred in the lower extremities, followed by injuries to the upper extremities, trunk, and head. Most injuries occurred during training (56,5%). The respondents were classified into three age groups (pre-cadets, cadets, and juniors). A statistically significant difference in training load between injured and non-injured respondents of junior and cadet age was recorded, while no statistically significant difference was visible among pre-cadet respondents.
