摘要
目的探讨400米障碍训练伤与核心力量训练时间的关系,并分析影响训练伤发生的相关因素。方法以参加400米障碍训练的207名学员为研究对象,2018年3月调查学员的一般身体数据、训练伤史、过去6个月进行核心力量训练的情况等数据;并于2018年3-4月对该人群进行为期2个月的400米障碍训练;分析训练伤史、训练时的腰围和体质量指数(BMI)与400米障碍训练伤发生的关系。结果在2个月的400米障碍训练中,共59人(占30.41%)发生63例次训练伤,其中上肢损伤5例次(占7.94%),下肢损伤55例次(占87.30%),躯干损伤3例次(占4.76%)。有受伤史的学员发生训练伤的比例更高(52.54%vs 22.22%,P=0.000)。核心训练时间越长,训练伤发生比例越低(Linear by linear associatationχ~2=6.970,P=0.008)。多元logistic回归发现训练时间<4 h的学员发生训练伤的风险是≥4 h的学员2.369倍;且BMI每增加1 kg/m^2,训练中发生训练伤的风险增加1.259倍(P=0.017)。结论加强核心力量训练,控制BMI,有助于减少400米障碍训练伤发生风险。
Objective To explore the relationship between training injuries and core strength training time in the 400-meter obstacle course,and analyze the possible influencing factors of training injuries.Methods Data were collected from 207 military school students,including height,waist circumference,weight and BMI,training injury history and core strength training in the past six months by questionnaire survey.Then the students took part in the two-month 400-meter obstacle course from March to April in 2018.The binary logistic regression analysis was applied to analyze the relationship between training injury history,waist circumference,BMI during training and the occurrence of 400-meter obstacle training injury.Results A total of 63 cases of training injuries from 59 students(30.41%)occurred during the two-month 400-meter obstacle training,including 5 cases of upper limb injury(7.94%),55 cases of lower extremity injury(87.30%),and 3 cases of trunk injury(4.76%).Training injury was more likely to occur in students with a history of injury(52.54%vs 22.22%,P=0.000),and the students who paticipated less core strength training(<4 h vs≥4 h:2.65%vs 23.81%,P=0.009).Logistic regression showed that the risk of training injury increased 1.259 times with the increase of every one unit of BMI index;Training less than 4 hours(OR,3.488;95%CI,1.766 to 6.889)and history of sports injury(OR,2.369;95%CI,1.204 to 4.661)increased the risk of injury in 400-meter obstacle training.Conclusion At least 4 hours of core strength training per week and BMI control will help to reduce the risk of training injuries in 400m obstacle training.
