Introduction: People with varying degrees of physical disability play wheelchair basketball because their diagnosis makes it impossible for them to run, jump and turn around. The International Wheelchair Basketball Federation is the world organization for wheelchair basketball. According to the rules, wheelchair basketball doesn't differ significantly from basketball. The most common causes of wheelchair basketball disabilities are spinal cord injuries, spina bifida, polio, and amputations. In wheelchair basketball players, injuries to the joints of the shoulders, elbows and hands are common. Objectives: The main objective of the study was to determine whether a higher number of injuries occur in the upper or lower extremities in wheelchair basketball players. Furthermore, to determine whether wheelchair basketball players who are 30 and over 30 year old are injured more often than younger wheelchair basketball players and determine the cause of injuries. Also determine if basketball players perform stretching exercises after training. Subjects and methods: The study involved 40 wheelchair basketball players from the Croatian Wheelchair Basketball Association, 36 men and four women. The research was conducted through an online anonymous survey. The data were analyzed in Microsoft Excel 2019 and Statistica 14.0.0.15 by TIBCO Software Inc.. The data were processed statistically and presented in tables and graphs. Descriptive statistics for nominal variables implies the display of frequencies, and for the relative variables the arithmetic mean and standard deviation. The level of statistical significance will be expressed as P < 0.05. Results: Research has shown that most wheelchair basketball players suffered more injuries in the upper 76%, than in the lower extremities. Furthermore, it was shown that older players are more frequently injured than younger. It has been established that the most common cause of injuries is their own carelessness and that most wheelchair basketball players perform stretching exercises after training. Conclusion: According to the results of the research, wheelchair basketball players should be encouraged to prevent injuries, which would greatly prevent the occurrence of new injuries. Further research is needed on the topic of wheelchair basketball injuries with a focus on the motivation of wheelchair basketball players to prevent injuries.
