Evidence suggests that athletically trained individuals are more accurate than untrained individuals in updating their spatial position through idiothetic cues. We assessed whether training at different spatial scales affects the accuracy of path integration. Groups of rugby players (large-scale training) and martial artists (small-scale training) participated in a triangle-completion task: they were led (blindfolded) along two sides of a right-angled triangle and were required to complete the hypotenuse by returning to the origin. The groups did not differ in their assessment of the distance to the origin, but rugby players were more accurate than martial artists in assessing the correct angle to turn (heading), and landed significantly closer to the origin. These data support evidence that distance and heading components can be dissociated. Furthermore, they suggest that the spatial scale at which an individual is trained may affect the accuracy of one component of path integration but not the other.
有证据表明，相对于未经训练的个体，经过运动训练的个体在通过自身运动感觉线索来更新空间位置时更为准确。我们评估了在不同空间尺度上进行训练是否会影响路径整合的准确性。一组橄榄球运动员（大尺度训练）和武术家（小尺度训练）参与了一个三角形完成任务：他们被蒙住眼睛沿着一个直角三角形的两条边行走，然后需要返回原点来完成斜边。两组人在对原点距离的评估上没有差异，但橄榄球运动员在评估正确转弯角度（朝向）方面比武术家更准确，并且更接近原点着陆。这些数据支持了距离和朝向两个组成部分可以分离的证据。此外，它们表明个体接受训练的空间尺度可能会影响路径整合的一个组成部分的准确性，但不会影响另一个组成部分。
