Introduction: Running is an activity that is done to move faster, but it will not be effective if there are injuries that interfere with performance.Objective:To examine the running speed of students with a history of ankle injuries regarding their running performance.Methodology: This study's approach consists of a one-time case study design and descriptive analytics. 14 out of 120 samples were found to have a history of ankle injuries based on test and measurement results as well as physiotherapy evaluations.Kinovea software version 0.9.5 was utilized to analyze the video recordings that were used as the research instrument. Results: This study found that the highest running speed was 19.91 m/s, with a stance phase time of 0.345 ± 0.040 seconds. Running speed can be affected by data-derived variables like stride length and knee flexion angle. Discussion: According to this study, those with ankle injuries had an average stride length of 1.75 meters, while healthy people in the good category had an average stride length of 1.51 meters. The ankle flexion angle of a normal person is about 90 degrees, however the findings in this investigation showed that it was about 181.05 degrees.Conclusions: This study indicated that students with a history of ankle injuries run less effi-ciently than healthy individuals. This study explains that when the injured leg is moved, it will move faster to reduce pain, particularly when the injured portion of the footcontacts the ground or another plane. Future research is anticipated to analyze running speed on a flat track to compare the injury risk associated with various track contours and running performance
