本研究探讨了运动系统的自由度是如何组织熟练的球员进行足球削片任务。使用内部参与者的分析，个体间的运动学和性能差异进行了研究，以确定熟练的削片动作的协调功能。五个熟练的参与者进行了研究，因为他们执行10个足球芯片到一个目标位置和另外15个足球芯片到三个位置，所有这些都具有不同的特定高度和精度任务限制。虽然一个“全球协调模式”被确定为熟练的足球削，微妙的个体间的差异，协调，位移的质量中心（COM），选定的运动学变量的踢肢和非踢肢的作用也被观察到。据指出，参与者能够适应不同的目标位置，成功地满足任务目标的脚的速度。结果突出了检查参与者内部数据的优势，以了解熟练的表演者如何重新组织运动系统的自由度，实现功能性运动行为。
This study investigated how motor system degrees of freedom were organized as skilled players performed a soccer chipping task. Using an intra-participant analysis, inter-individual kinematics and performance differences were investigated to determine the features governing coordination of skilled chipping actions. Five skilled participants were studied as they performed 10 soccer chips to one target position and another 15 soccer chips to three positions, all with different specific height and accuracy task constraints. Although a ‘global coordination pattern’ was identified for skilled soccer chipping, subtle inter-individual differences in coordination, displacement of center of mass (COM), selected kinematic variables for the kicking limb and the role of the non-kicking limb were also observed. It was noted that participants were able to adapt foot velocity to different target positions in successfully meeting the task goal. Results highlighted advantages of examining intra-participant data for understanding how skilled performers re-organize motor system degrees of freedom in achieving functional movement behaviors.
