摘要
目的:探索在连续纵跳下落阶段优势侧和非优势侧踝关节的运动学、地面反作用力差异。方法:采用13名健康男性作为受试者,每名受试者进行连续纵跳5次,以起跳时的重心高度作为标准,选取5次中最好成绩动作的下落阶段进行分析。运动过程中采集两侧下肢的地面反作用力以及两侧踝关节的运动学数据,利用配对t检验对所采集的两侧数据进行分析。结果:在连续纵跳的下落阶段,优势侧踝关节的背屈方向和外旋方向上的角速度、垂直方向上的地面反作用力均大于非优势侧(P<0.05),但踝关节的其他运动学、动力学指标均没有显著性差异。结论:在连续纵跳的下落阶段,与优势侧相比,非优势侧可能在屈伸与外旋方向有较大的运动限制,而与非优势侧相比,优势侧在下落着地过程中出现运动损伤的可能性较大。
Objective：To compare the differences between dominant-side and non-dominant-side ankle kinematics and ground reaction force during landing stage in repeated vertical jump. Method： Thirteen healthy adults were recruited to perform the repeated vertical jump from platforms five times with both legs. The height of the center of gravity is used as the standard to choose the best jumping for analysis. The ground reaction force, ankle kinematics were measured in both lower extremities. Paired t test was used to analyze the effects of laterality. Result： The peak angular velocities in dorsiflexion and inversion of dominant-side were significantly higher than the non-dominant-side during dropping stage in repeated vertical jump（P〈 0.05）, and no significant differences were found in most of the kinematic and kinetic variables. Conclusion.. Compared with the dominant side, the non-dominant side has greater restraint in ankle flexor and abduction activity, meanwhile, the dominant side is in greater injury risk during landing.
