Previous research on fielding in cricket and baseball has focused on the technique and speed-accuracy trade-off of the throw in isolation from a typical sequence of fielding actions; approach, gather and throw. The present study aimed to determine whether a speed-accuracy trade-off existed in fielding and where within the above sequence the trade-off occurs. Participants, who were elite cricketers, were required to run to a stationary ball and throw to the centre of a target in order to run-out a virtual batter. High-speed video was used to record the time of approach, time in contact with, and time of flight of the ball. Two-way ANOVAs were used to determine differences in group (gender) and condition (instructions to prioritise speed or accuracy). A speed-accuracy trade-off was found, with both groups being quicker in the approach and spending less time in contact with the ball in the speed condition; however, the horizontal velocity of the throw remained the same in both conditions. It was proposed the drop in accuracy in the speed condition may be associated with less time spent aiming. It was found that instructions triggered a change in throwing technique for 31% of the participants, which requires further investigation.
先前关于板球和棒球防守的研究主要集中在投球技术和速度-准确性权衡上，而这些研究将投球与防守动作的典型序列（接近、收集和投球）隔离开来。本研究旨在确定防守中是否存在速度-准确性权衡，以及在上述序列中的哪个位置发生这种权衡。参与者是精英板球运动员，他们需要跑到一个静止的球前，并将球投向目标的中心，以将虚拟击球手淘汰出局。高速摄像机用于记录接近球的时间、与球接触的时间和球的飞行时间。双向方差分析用于确定组（性别）和条件（优先考虑速度或准确性的指令）之间的差异。研究发现存在速度-准确性权衡，两个组在速度条件下的接近速度更快，与球接触的时间更短；然而，在两种条件下，投球的水平速度保持不变。据推测，在速度条件下准确性下降可能与瞄准时间减少有关。研究发现，指令触发了 31%的参与者改变了投掷技术，这需要进一步研究。
