This study addressed the paucity of evidence of whether visual anticipation can be improved in emerging experts in striking sports. Twelve emerging expert batsmen from a state cricket squad were equally randomised into intervention and control groups. They were pre-and-post tested on a video temporal occlusion test of a fast bowler, as well as transfer tests of different fast and slow bowlers. The intervention group received two sessions per week of point-light display temporal occlusion training with motor practice of the observed bowler's action over a 4-week period. The control group completed only the testing phases. Batting averages before, during, and after the study were recorded for both groups. The intervention group, but not the control group, improved anticipation to significantly above chance level across pre-to-post-tests based upon pre-ball flight information. The intervention, but not the control, transferred their learning to anticipate significantly above chance level based upon pre-ball flight information across different fast and slow (spin) bowlers. Batting average of the intervention group was higher than the control group during the study. Findings indicate that the intervention can improve anticipation in emerging expert batsmen, beyond sport-specific practice. This improvement may benefit competition performance, but further evidence is required.
本研究旨在探讨在新兴的击球运动专家中,视觉预判是否可以得到提高。从一个州板球队中随机抽取了 12 名新兴的专家击球手,将他们平均分为干预组和对照组。在对快速投球手进行视频时间遮挡测试以及对不同快速和慢速投球手进行转移测试之前和之后,他们都接受了测试。干预组在 4 周的时间里,每周接受两次点光显示时间遮挡训练,并结合对观察到的投球手动作进行练习。对照组只完成了测试阶段。在研究前后,记录了两组的击球平均成绩。干预组在基于球前飞行信息的预判中,预判能力显著提高到高于随机水平,而对照组则没有。干预组将他们的学习能力转移到了基于球前飞行信息的不同快速和慢速(旋转)投球手的预判中,预判能力也显著提高到高于随机水平。在研究期间,干预组的击球平均成绩高于对照组。研究结果表明,该干预措施可以提高新兴专家击球手的预判能力,超越特定运动的练习。这种提高可能有利于比赛表现,但还需要进一步的证据。
