Purpose: To evaluate the relationship between specific aspects of core stability and knee injury risk factors during drop-jump (DJ) landing.

Methods: Eighteen college-aged male amateur basketball players participated in the project. Kinetic and kinematic data for DJ tasks were collected with force plates and infrared cameras. Raw data were processed to calculate knee joint angles and joint moments during DJ landing. Different components of core stability were represented by the sit-ups in 20 s (SU), trunk extensor endurance, trunk flexion and extension range of motion, dominant extremity single-leg stance time (DLS), and dominant extremity single-leg hop distance, respectively.

Methods: Correlation and regression were used to determine the relationship between jumping-related biomechanical parameters and core stability components.

Results: SU shared significant variance with the peak moment of knee extension (PMKE, p < 0.05), the peak moment of knee abduction (PMKA, p < 0.05), and the angle of knee internal rotation at initial contact (AKRI, p < 0.05). DLS shared significant variance with the angular motion of knee internal rotation (AMKR, p < 0.05) and the AKRI (p < 0.01). SU and DLS together could explain 52% of the variance observed in the AKRI, and the result was significant.

Conclusion: Core stability’s strength and motor control aspects played an essential role in preventing knee injury during DJ landing. An integrative training program addressing core strength and motor control could be considered for coaches and athletes to prevent knee injury through core training and conditioning.

目的： 评估跳伞 (DJ) 着陆期间核心稳定性的特定方面与膝关节损伤风险因素之间的关系。

方法：十八名大学年龄的男性业余篮球运动员参加了该项目。DJ 任务的动力学和运动学数据是用测力台和红外摄像机收集的。处理原始数据以计算 DJ 着陆期间的膝关节角度和关节力矩。核心稳定性的不同组成部分由 20 秒仰卧起坐 (SU)、躯干伸肌耐力、躯干屈伸运动范围、优势肢单腿站立时间 (DLS) 和优势肢单腿跳跃距离表示， 分别。

方法： 相关性和回归被用来确定跳跃相关的生物力学参数和核心稳定性分量之间的关系。

结果： SU 与膝关节伸展的峰值力矩 (PMKE, 磷 < 0.05), 膝外展峰值力矩 (PMKA, 磷 < 0.05），以及初始接触时膝关节内旋角（AKRI， 磷< 0.05)。DLS 与膝关节内旋角运动（AMKR，磷 < 0.05) 和 AKRI (磷< 0.01)。SU 和 DLS 一起可以解释 AKRI 中观察到的 52% 的方差，结果是显着的。

结论：核心稳定性的力量和运动控制方面在防止 DJ 着陆时膝盖受伤方面发挥了重要作用。教练员和运动员可以考虑针对核心力量和运动控制的综合训练计划，通过核心训练和体能训练来预防膝关节损伤。
