投掷速度和准确性对运动成绩都至关重要，但不能同时优化。这种速度-准确性权衡（SATO）在许多投掷组中是明显的，但仍然知之甚少。目标是描述棒球和板球运动员的SATO，并确定优化准确性的速度。20名年级水平的棒球和板球运动员以80%和100%的最大投掷速度（MTS）向板球树桩投掷10次。棒球运动员然后在MTS的70%，80%，90%和100%的情况下向圆形目标进行另外10次投掷。棒球运动员在两种速度下都比板球运动员投得更快，更准确。两组都表现出显著的SATO，因为垂直误差随着速度的增加而增加;板球运动员的权衡比棒球运动员更糟糕。准确性优化在70%的MTS为棒球运动员。投掷运动员在准确性至关重要时应降低速度。板球运动员可以通过棒球训练来提高投掷成绩。
Throwing speed and accuracy are both critical to sports performance but cannot be optimized simultaneously. This speed-accuracy trade-off (SATO) is evident across a number of throwing groups but remains poorly understood. The goal was to describe the SATO in baseball and cricket players and determine the speed that optimizes accuracy. 20 grade-level baseball and cricket players performed 10 throws at 80% and 100% of maximal throwing speed (MTS) toward a cricket stump. Baseball players then performed a further 10 throws at 70%, 80%, 90%, and 100% of MTS toward a circular target. Baseball players threw faster with greater accuracy than cricket players at both speeds. Both groups demonstrated a significant SATO as vertical error increased with increases in speed; the trade-off was worse for cricketers than baseball players. Accuracy was optimized at 70% of MTS for baseballers. Throwing athletes should decrease speed when accuracy is critical. Cricket players could adopt baseball-training practices to improve throwing performance.
