Causes and prevention of anterior cruciate ligament injury caused by 400-meter barrier training

Objective To investigate the locations and causes of anterior cruciate ligament (ACL) injury during 400-meter barrier training, and to propose precautions. Methods The subjects were soldiers who were hospitalized due to ACL injury in Guangxi Autonomous Regional Crops Hospital between January, 2017 and December, 2019. The detailed medical history of these patients was recorded, including the types of training that had led to ACL injury. Locations and causes of ACL injury related to 400-meter barrier training were specified. Results Ninety-two cases of ACL injury were collected. 400-meter barrier training caused the largest number of cases of ACL injury (48cases, 52.2%). During 400-meter barrier training, ACL injury often occurred when soldiers jumped off the high horizontal ladder (31.3%) and the single-plank bridge (27.1%). Common causes of ACL injury included inadequate warm-up (25.0%), a lack of specific warm-up, and poor-quality fields (18.8%), mainly involving a hard landing area. Conclusions During 400-meter barrier training, soldiers are most vulnerable to ACL injury that often occurs when soldiers directly jump off the high horizontal ladder and the single-plank bridge with nothing for support. The chance of ACL injury can be reduced by means of effective warm-up.
