摘要

本研究调查了当投球手的动作操纵场地放置一致性时,熟练的击球手是否可以预测球的类型。招募了24名男子板球击球手,他们要么打过一流板球(n = 6),要么是17岁以下(n = 8)或19岁以下(n = 10)州板球队的一员。参与者完成了一个基于视频的颞遮挡测试,他们被要求预测投球手打出的球的类型。在第一种情况下,情境场地放置信息被呈现为与投球类型和投球手的动作一致,而在第二种情况下,情境场地放置信息是不一致的。结果并没有显示不同条件下预期的技能水平差异。在一致的条件下,所有技能组在投球手的投球步幅开始和结束时的预测都高于机会水平。在不一致条件下,一流球员在投球步幅开始时的预测高于机会,并且在投球释放时的预测高于其他技术组的概率。17岁以下和19岁以下球员在投球步幅开始时无法预测以上概率,其预测量低于一流球员在投球步幅开始时的预测量。结果表明,熟练的击球手发现整合上下文和运动信息来预测是具有挑战性的。这可能是由于更加强调部分由数据分析师提供的上下文信息。研究结果分别对下半身定位球拦截和知觉训练提高运动线索的拾取具有理论和实践意义。技术娴熟的击球手在一个高性能的状态板球途径可以整合一致的场地布局和投球手的运动学预测球的类型。一流的击球手可以将不一致的场地定位信息整合到投球手投球动作的开始,而不是结束,以预测球的类型。17岁和19岁以下的击球手无法将不一致的场地位置与投球手的运动学相结合,以预测球的类型。熟练的击球手不能使用运动学信息来预测球的类型,应该给予视觉感知模拟训练来加速表现。

Reliance upon contextual information can impede visual anticipation.

This study investigated whether skilled batsmen in a state cricket pathway could anticipate ball types when congruency of field-placings was manipulated with a bowler's action. Twenty-four male cricket batsmen were recruited who had played either first-class cricket (n = 6), were part of under 17 (n = 8) or under 19 (n = 10) state cricket squads. Participants completed a video-based temporal occlusion test where they were required to anticipate ball types from a swing bowler. In condition one, contextual field-placing information was presented to be congruent with the delivery type and bowler's action, whilst in condition two it was incongruent. Results did not reveal skill level differences across conditions for anticipation. In the congruent condition, all skill groups predicted above the chance level at the beginning and end of the bowler's delivery stride. In the incongruent condition, first-class players predicted above chance at the beginning of the bowler's delivery stride, and to a higher magnitude above chance compared to other skill groups at ball release. Under 17 and 19 players could not predict above chance at the start of the bowler's delivery stride with their magnitude of prediction lower than first-class players at ball release. Results indicate skilled batsmen find it challenging to integrate contextual and kinematic information to anticipate. This is likely due to greater emphasis placed upon contextual information in part supplied by data analysts. Findings have theoretical and practical implications respectively for lower body positioning for bat-ball interception and perceptual training to improve pick-up of kinematic cues.HIGHLIGHTSSkilled batsmen in a high-performance state cricket pathway could integrate congruent field-placings and bowler kinematics to anticipate ball types.First-class batsmen could integrate incongruent field-placing information to the start, but not the end, of the bowler's delivery action to anticipate ball types.Under 17 and 19 batsmen could not integrate incongruent field-placings to bowler kinematics to anticipate ball types.Skilled batsmen who cannot use kinematic information to anticipate ball types should be given visual-perceptual simulation training to accelerate performance.
