Background: This study aimed to investigate the relationship between trunk endurance and functional tests related to lower limb injury in students of Imam Ali (AS) Military Universi-ty. Methods: For this study, 90 students of the officer university with average age: 20.86 ± 1.56 year, height: 1.78 ± 0.05 meters, weight: 72.76 ± 8.46 kg and BMI: 22.73 ± 2.30 kg/m2 were selected by availability. In this study, Core endurance was assessed with the McGill test set. The Static and dynamic balance were also assessed by stork and Y balance tests, respectively. Single leg hop, triple crossover hop for distance and timed single leg hop tests were used to assess lower limb function. Since the number of subjects was 90, Kolmogo-rov-Smirnov test was used to assess the normality of data distribution; Due to the normality of data distribution to investigate the relationship between predictor variables and criterion variable, Pearson correlation coefficient method was used with a significance level of 0.05. Results: The results of Pearson statistical test showed that there is a significant relationship between McGill endurance tests and also the total endurance score with static balance (p=0.008), total dynamic balance score (p=0.003), single leg hop test (p=0.001), triple crossover hop for distance test (p=0.005). But the relationship between endurance and timed single leg hop test was not significant (p <0.05). In general, the results of this study showed that there is a relationship between postural stability, muscle endurance and functional tests related to lower limb injury in officer University students. Conclusions: It can be interpreted that the injury-related functional tests such as single leg hop test and triple crossover hop for distance test of the students who can take their body Move forward in a controlled way are better. Moreover, it can be considered that the postural stability of the students with high core muscle endurance is higher. Therefore, it is important to apply exercise programs that enhance postural stability and increase core muscle endurance to improve functional suc-cess.
