This study examined the perceptual attunement of relatively skilled individuals to the physical properties of striking implements in the sport of cricket. We also sought to assess whether utilizing bats with different physical properties would influence performance of a specific striking action: the front foot straight drive. Eleven skilled male cricketers (mean age = 16.6 ± 0.3 years) from an elite school cricket development program consented to participate in the study. While blindfolded, participants wielded six bats exhibiting different mass and moment of inertia (MOI) characteristics and were asked to identify the three bats they preferred the most for hitting a ball to a maximum distance by performing a front foot straight drive (a common shot in cricket). Next, participants actually attempted to hit balls projected from a ball machine using each of the six bat configurations to enable kinematic analysis of front foot straight drive performance with each implement. Results revealed that, on first choice, the two bats with the smallest mass and MOI values (1 and 2) were most preferred by almost two thirds (63.7 %) of the participants. Kinematic analysis of movement patterns revealed that bat velocity, step length, and bat-ball contact position measures significantly differed between bats. Data revealed how skilled youth cricketers were attuned to the different bat characteristics and harnessed movement system degeneracy to perform this complex interceptive action.
本研究考察了相对熟练的个体对板球运动中击球器具物理特性的感知协调能力。我们还试图评估使用具有不同物理特性的球棒是否会影响特定击球动作的表现:前脚直线击球。来自一所精英学校板球发展项目的11名熟练男性板球运动员(平均年龄 = 16.6 ± 0.3岁)同意参与该研究。在蒙眼状态下,参与者挥舞六根具有不同质量和转动惯量(MOI)特性的球棒,并被要求通过执行前脚直线击球(板球中的一种常见击球方式)来找出他们最倾向于用来将球击至最大距离的三根球棒。接下来,参与者实际尝试使用六种球棒配置中的每一种来击打从投球机投射出的球,以便对每种器具的前脚直线击球表现进行运动学分析。结果显示,在首次选择时,几乎三分之二(63.7%)的参与者最喜欢质量和MOI值最小的两根球棒(1号和2号)。对运动模式的运动学分析表明,不同球棒之间的球棒速度、步长和球棒与球的接触位置测量值存在显著差异。数据揭示了熟练的年轻板球运动员如何适应不同的球棒特性,并利用运动系统的简并性来执行这种复杂的拦截动作。
