Abstract: BACKGROUND: The landing error scoring system test is a standard for assessing the risk of non-contact injuries and has not yet been developed for Chinese college soccer programs.
Objective: To establish a test evaluation standard for the landing error scoring system to provide a basis for evaluating the risk of non-contact injuries in college soccer students.
Methods: A prospective cohort study was designed in which 219 athletes from 10 college soccer teams were tested with the standard landing error scoring system, and the subjects were followed up by questionnaires and medical examinations for non-contact injuries of the lower extremities and trunk for 1 year after testing to determine sex differences and assessment criteria for the landing error scoring system test indicators.
Results AND Conclusion: The total score of the landing error scoring system was (8.22±1.65) points for 219 subjects, (8.29±1.74) for males and (8.07±1.44) for females, with no significant difference between males and females (P > 0.05). Within 1 year after the test, the overall injury rate of 219 subjects was 10.05% and the morbidity rate was 15.98%; the injury rate of male subjects with non-contact injury of the lower limbs and trunk was 12.75% and the morbidity rate was 20.13%; the injury rate of female subjects with non-contact injury of the lower limbs and trunk was 4.29% and the morbidity rate was 7.14%. There were no significant differences in the injury rate between men and women (P < 0.05). The total score of the landing error scoring system was higher in the injury group than in the non-injury group [(9.50±1.14) vs. (8.08±1.64), P < 0.01]; for male subjects, the total score of the landing error scoring system was higher in the injury group than in the non-injury group [(9.63±1.12) vs. (8.09 ± 1.73), P < 0.01]. The area under the curve for the total score of the landing error scoring system was 0.773 (P=0.000), which had a diagnostic value for the risk of non-contact injury of the lower extremities and trunk in male subjects, with a best cut-off point of 8.5, sensitivity of 0.842, specificity of 0.623, positive likelihood ratio of 2.233, negative likelihood ratio of 0.254, relative risk factor of 8.400, and odds ratio of 8.816; the total score of the landing error scoring system was not applicable for assessing the risk of non-contact injury of the lower extremities and trunk in female subjects. To conclude, the landing error scoring system test can be used as a criterion to assess the risk of non-contact injury to the lower extremity and trunk in Chinese college male soccer players, with an optimal cut-off point of 8.5. The risk of non-contact injury to the lower extremity and trunk is 8.40 times higher in male athletes with a landing error scoring system test score of ≥ 8.5 than in male athletes with a score of < 8.5.
