In this study, we examined the effects of relative positioning of attacker-defender dyads to the basket on interpersonal coordination tendencies in basketball. To achieve this aim, four right-hand dominant basketball players performed in a 1 vs. 1 sub-phase, at nine different playing locations relative to the basket (from 0° to 180°, in 20° increments). Performers' movement displacement trajectories were video-recorded and digitized in 162 trials. Results showed that interpersonal coordination tendencies changed according to the scaling of the relative position of performers to the basket. Stable in-phase modes of coordination were observed between performers' longitudinal and lateral displacements (50.47% and 43.02%) on the left side of the court. On the right side of the court, a shift in the dominant mode of coordination was observed to a defender lead-lag of -30°, both for longitudinal and lateral displacements (30.51% and 32.65%). These results suggest how information about dribbler hand dominance and relative position to the basket may have constrained attacker-defender coordination tendencies in 1 vs. 1 sub-phases of basketball.
在这项研究中，我们考察了攻击者-防御者对偶体相对于篮筐的相对位置对篮球中人际协调趋势的影响。为了达到这个目的，四名惯用右手的篮球运动员在 1 对 1 的子阶段中，在距离篮筐 0°到 180°，每隔 20°的九个不同位置进行了表演。表演者的运动位移轨迹在 162 次试验中被视频记录并数字化。结果表明，人际协调趋势根据表演者相对于篮筐的相对位置的缩放而变化。在球场的左侧，表演者的纵向和横向位移（50.47%和 43.02%）之间观察到稳定的同相协调模式。在球场的右侧，观察到主导协调模式向防守者滞后 30°的转变，纵向和横向位移都是如此（30.51%和 32.65%）。这些结果表明了关于运球手优势和相对于篮筐的相对位置的信息如何在篮球 1 对 1 子阶段中限制了攻击者-防御者的协调趋势。
