Wakeboard is an aquatic sport that has being growing in number of participants in several countries last years. Brazil, as a tropical country with extensive water source, provides an ideal condition for its practice and it has grown in the world professional scenario with some high-level athletes. Like other aquatic sports with high-speed and tricks with complex movements, wakeboarding involves a series of risks to practitioners and, as a relatively new sport, there are few scientific publications, and most of them are case reports. Objective: identify the most frequent injuries related to wakeboard practice and correlates with intrinsic variables, such age, sex, body mass index, and extrinsic ones, such modality, frequency, and level of practice. Method: It is a prospective cross-sectional study among wakeboarders from different regions of the country, in which it has been collected demographic information, data inherent to the practice of the sport and information regarding the types of injuries presented by the participants. For this, a questionnaire from Google Forms platform was used and the data was analyzed by SPSS software, version 22, with chi-square test when applicable. Results: The research had 157 valid responses, from which 124 (79%) declared to have had at least one injury related to wakeboarding. At total, it was reported 319 injuries, 34% of them was skin wounds, 27% muscular, 20% sprains, 7% joint dislocations, 7% bone fractures, 4% concussions and 1% others. 4% of them was related to equipment failure, such inadequate size of boots or binding loose fixation. Men had a relative risk of 1,47 of being injured compared to women (IC 1,06-2,05, p=0,002). There were no statistically significant differences when compared different ages, body mass index (BMI) or modality (boat or cablepark). From the general musculoskeletal harms, 82% of the sprains and 50% of the bone fracture occurred on inferior limbs, as the superior limbs was most affected on muscular injuries (35%) and joint dislocation (87%). Sprains were most common in the knee (46%) and ankle joints (36%), and 70% of the sprains with ligament involvement affected the anterior cruciate ligament. 78% of the joint dislocation occurred on the shoulder. Conclusions: Wakeboard has a high prevalence of injuries, most of them on the skin and musculoskeletal ones. Men have higher injury rate than women and there were no association with age, BMI or modality. Equipment failure is a predisposing factor for harms and the higher the frequency and level of practice, the higher the chances of getting injured.
