Abstract

Differences in interceptive skill between highly skilled and lesser skilled cricket batsmen were examined using a batting task that required participants to strike front-foot drive strokes from a machine-projected ball to a specified target. Task difficulty was manipulated by varying the width of the bat (normal, half, and third width) and target accuracy, and quality of bat-ball contact was monitored along with temporal and sequential elements of the hitting action. Analyses revealed that the highly skilled batsmen were distinguishable from less skilled counterparts by their higher accuracy under the normal and half-width bat conditions, significantly earlier initiation and completion of the front-foot stride, greater synchronization of the completion of the front-foot stride with the commencement of the downswing of the bat, and consistent timing of downswing relative to ball bounce and impact. In keeping with studies of other hitting sports, temporal and spatial coupling of the downswing to ball bounce to help minimize temporo-spatial error at the point of interception appeared critical to skilled performance. Implications for the understanding of interception and for coaching practice are briefly discussed.

摘要

使用击球任务来检查高技能和低技能板球击球手之间的拦截技能差异,该任务要求参与者从前脚驱动击球,从机器投影的球击中指定目标。通过改变球棒的宽度(正常、一半和三分之一)和目标准确性来控制任务难度,并监测球棒接触的质量以及击球动作的时间和顺序要素。分析表明,高技能击球手在正常和一半宽度球棒条件下的准确性更高,前脚跨步的起始和完成时间更早,前脚跨步的完成与球棒向下挥动的起始时间更加同步,以及向下挥动相对于球弹跳和撞击的时间一致,这些特征使他们与低技能击球手区分开来。与其他击球运动的研究一致,为了最大限度地减少拦截点的时空误差,将向下挥动与球弹跳的时空耦合似乎对技能表现至关重要。简要讨论了对拦截的理解和教练实践的影响。
