Introduction Down syndrome (DS), a genetic cause of intellectual disability, presents physical impairments that may affect their motor performance behavior. Race video recording is essential both to provide feedback of swimmers’ performances and to analyze performance influencing factors. Since this has never been done for DS exclusively, the aim of this study is to analyze the 200-m backstroke event from the 5th DS World Championships. Methods The event was videotaped with two side view cameras, and 28 swimmers (15 men and 13 women) from the preliminary heats were analyzed for start, turn and swim times and stroke length (SL), rate (SR), and index (SI). Mean and SD were obtained, and Student t-tests were computed to compare gender groups. Pearson correlation analysis was performed between race components, stroking variables and end results (p
