The purpose of this study was to determine the relationship between Yo-Yo intermittent recovery testing ability and 20-meter sprint times in NCAA Division I men’s and women’s collegiate soccer players. Results show no significant (p = >0.05) relationship between the distance covered in the Yo-Yo IR1 test and 20-meter sprint times in the female players and a significant correlation between the two tests in the male players (r = -0.33). A non-significant relationship between the tests in female players may be due to greater variation in the total distance covered during the Yo-Yo IR1 test and small variation in 20-meter sprint times. The inclusion of speed and resistance training may be beneficial in developing the anaerobic speed reserve in female collegiate soccer players, leading to improvement in the Yo-Yo IR1 test performance. Improving the sprinting capabilities of male collegiate soccer players may also improve Yo-Yo IR1 test performance.
