• Abstract: This study aimed to analyze the key position movement differences among Northern Lion athletes withvarying training levels during the “Northern Lion 180° leap and direct leg stand on a high platform” action, in orderto guide the athletes in improving their movements and enhance the completion rate of the action. Method: TwoNorthern Lion tail athletes from a university, with training durations of 5 years and 1.5 years respectively, wereselected for the study. Their movements were filmed using a high-speed camera, capturing the “Northern Lion 180°leap and direct leg stand on a high platform” action. The APAS 3D motion analysis system was used to digitallyanalyze the videos, and SPSS software was employed for an independent samples t-test to derive the results. Results:(1) There were very significant differences in the center of gravity coordinates among Northern Lion athletes withdifferent training levels (p<0.01). Athletes with higher training levels had a lower and more backward center ofgravity; (2) The findings at the shoulder and hip joints were consistent with those of the center of gravity (p<0.01); (3) The knee joint angle of the high-level Lion tail was significantly greater than that of the low-level (p<0.01).Conclusion: Whether through visual observation or digital analysis, the differences in training levels are very evidentin the movements. 目的：本研究通过分析不同训练水平的北狮运动员在进行“北狮高台左右180°飞跃直接站腿”动作时关键位置的动作差异，指导北狮运动员进行动作改进以提高动作完成率。方法：对某高校训练年限分别为5年、1.5年的北狮狮尾大学生运动员各1名，对其动作进行拍摄，使用高速摄像机对两名运动员的“北狮高台左右180°飞跃直接站腿”动作进行拍摄，使用APAS三维运动解析系统对视频进行数字化解析，并用SPSS软件进行独立样本t检验，得出结果。结果：（1）不同训练水平的北狮运动员的重心点位坐标值存在非常显著的差异（p<0.01），训练水平高的北狮运动员重心更低并且更加靠后；（2）在肩关节与髋关节两处的发现均与重心点位的发现一致（p<0.01）；（3）高水平狮尾的膝关节角度明显大于低水平的膝关节角度（p<0.01）。结论：无论是通过图像观察还是通过数字化解析，训练水平的差异在动作上的表现都非常明显。
