The visibility of the pink ball used in day/night Test cricket has been under scrutiny, with recent research suggesting cricketers find the pink ball less visible at dusk under floodlights. With increasing interest in this match format, this study sought to investigate elite umpires' opinions pertaining to the visibility of the pink cricket ball during day/night matches.
Purposeful sampling of a cross-section of elite umpires with experience adjudicating matches played using a pink cricket ball.
Twenty-seven international/first-class umpires completed a questionnaire consisting of Likert scale and free text responses covering perceptions of the pink cricket ball, with a particular emphasis on visibility.
The pink ball when viewed at night under floodlights was rated as being significantly more visible than the red ball during natural lighting (ps<0.050). Umpires who actively participated in training reported a significantly higher rating of the visibility of the pink ball (mean -3.14) at night under floodlights compared to those who didn't (mean p=0.010). No significant difference was reported in visibility in natural light or dusk under floodlights. Free text responses (n=10) revealed the following themes: use of eyewear (coverage 0.30), and adjustment to positioning (coverage 0.20) to improve visibility of the pink ball.
Umpires report the visibility of the pink ball is equal to the red in natural light and at dusk but is significantly better at night. Preference for the pink ball is likely due to the predominantly perceptual nature of visual tasks performed by umpires.
日间/夜间板球测试中使用的粉色球的可见度一直受到关注,最近的研究表明,板球运动员在黄昏时在泛光灯下发现粉色球的可见度较低。随着对这种比赛形式的兴趣日益增加,本研究旨在调查精英裁判对日间/夜间比赛中粉色板球可见度的看法。
对有经验的使用粉色板球裁决比赛的精英裁判进行有针对性的抽样。
27 名国际/一流裁判完成了一份包含李克特量表和自由文本回复的问卷,涵盖了对粉色板球的看法,特别强调了可见度。
在泛光灯下的夜间,粉色球的可见度明显高于自然光下的红球(p<0.050)。积极参加培训的裁判报告称,在泛光灯下的夜间,粉色球的可见度评分明显更高(平均 -3.14),而没有参加培训的裁判则没有(p=0.010)。在自然光或泛光灯下的黄昏时,可见度没有显著差异。自由文本回复(n=10)揭示了以下主题:使用眼镜(覆盖率 0.30)和调整位置(覆盖率 0.20)以提高粉色球的可见度。
裁判报告称,粉色球在自然光和黄昏时的可见度与红球相等,但在夜间时明显更好。对粉色球的偏好可能归因于裁判执行的视觉任务主要是知觉性质。
