Biomechanical analysis can effectively identify factors associated with task performance and injury risk, but often does not account for the interaction among the components that underlie task execution. Uncontrolled manifold (UCM) analyses were applied to data from 38 female, adolescent athletes performing single-leg drop landings and were used to differentiate successful and unsuccessful task performance by examining the frontal plane joint variance within the UCM (VUCM) that stabilized the horizontal center of mass position (VUCM) and within the orthogonal subspace (VORT). The UCM revealed stronger coordination, indicated by the VUCM/VORT ratio, in the successful condition. This may inform future research examining reduced motor coordination in failed movement tasks and its relation to injury risk and allow for targeted interventions that consider coordination processes rather than joint-specific outcomes.

使用不受控制的流形分析区分成功和不成功的单腿降落性能。

生物力学分析可以有效地识别与任务绩效和伤害风险相关的因素，但通常不会考虑构成任务执行基础的组件之间的相互作用。不受控制的流形 (UCM) 分析应用于 38 名女性青少年运动员执行单腿下降着陆的数据，并用于通过检查稳定水平中心的 UCM (VUCM) 内的额面关节方差来区分成功和不成功的任务表现质量位置 (VUCM) 和正交子空间 (VORT) 内。在成功的情况下，UCM 显示出更强的协调性，由 VUCM/VORT 比率表示。
