Abstract: Objective: To explore the relationship between FMS and YBT test scores and sports injuries of Chinese elite military pentathlon athletes. Methods: Forty-four elite male and female military pentathlon athletes were tested by FMS and YBT, and the injuries during training were analyzed. The relationship between FMS and YBT test scores and injuries were analyzed. The results showed that: (1) The injury rate of elite military pentathlon athletes was high (52.27%) , The main injury sites were shoulder, waist and knee, accounting for about 77% of injury. (2) The FMS score of the injured athlete was 14.22 points, significantly (p <0.01) lower than the 16.67 points of the non-injured athlete. (3) The accuracy of damage prediction was 73.91% when FMS≤15 was used as the threshold to determine the damage, and the accuracy of damage prediction was 82.61 when the thresholds of X, Y, Z> 4 cm on both sides of YBT were used to determine the damage threshold.(4) The accuracy of the damage prediction is 100% when the combination of the two methods takes FMS≤15 points and X, Y, Z> 4 cm as the threshold value on both sides of YBT test. Conclusion: Both FMS and YBT tests can effectively predict the potential injury risk of military pentathlon athletes. If two test methods are combined, the accuracy of predicting the potential injury risk of athletes is better than that of single test method. It is suggested that when predicting the potential injury risk of athletes, the two test methods should be combined, and the weak links shown in the test should be targeted to improve the effect of injury prevention.
