背景胫骨应力性骨折（TSFs）对皇家海军陆战队新兵造成了巨大的负担。没有前瞻性的运行步态分析以前进行了在military setting.Aim我们的目的是确定生物力学步态因素和人体测量变量与TSF.Methods的风险增加1065皇家海军陆战队新兵进行了评估，在第2周的训练。双侧足底压力和三维下肢运动学获得赤脚跑在3.6米/秒，提供动态足弓指数，峰值足跟压力和下肢关节角度。记录年龄、双踝宽、小腿围、被动髋关节内/外活动度和体重指数（BMI）。对10名新兵在训练中发生TSF的情况与120名新兵在训练中无损伤的情况进行比较，采用二元Logistic回归模型确定损伤危险因素。
Background Tibial stress fractures (TSFs) cause a significant burden to Royal Marines recruits. No prospective running gait analyses have previously been performed in military settings.Aim We aimed to identify biomechanical gait factors and anthropometric variables associated with increased risk of TSF.Methods 1065 Royal Marines recruits were assessed in week 2 of training. Bilateral plantar pressure and three-dimensional lower limb kinematics were obtained for barefoot running at 3.6 m/s, providing dynamic arch index, peak heel pressure and lower limb joint angles. Age, bimalleolar breadth, calf girth, passive hip internal/external range of motion and body mass index (BMI) were also recorded. 10 recruits who sustained a TSF during training were compared with 120 recruits who completed training injury-free using a binary logistic regression model to identify injury risk factors.Results 4 variables significantly (p
