In order to improve the short stride athletes’ technical action and increase competition results, this research first establishes the optimal take-off angle model of hurdles according to the gravity acceleration, resistance coefficient and other factors.And according to the top three achievements of the 1980-2012 period nine Olympic Gamesmen’s 110meters hurdles, it uses gray prediction model to forecast the top three achievements of the next-two Olympic 110-meter hurdles. The results show that the top three achievements of the 2016 Olympic 110 meters hurdles are respectively 12.82 seconds, 13.03 seconds and 13.07 seconds; achievements in 2020 are 12.79 seconds, 13.02 seconds and 13.03 seconds; the achievement of Olympic Games overall is increasing year by year. The research result is conductive to hurdler achievement’s improvement, and provides certain scientific basis for its day-to-day training.
