In recent years there have been many alterations to equipment and technology in professional cricket, including the introduction of white balls during day-night matches. In the present study simulated slip-catching performance and movement initiation time were examined in professional cricketers when ball colour and illuminance levels differed. Five male professional cricketers (mean age: 27.3 +/- 1.4 years) volunteered to catch a total of 60 cricket balls, 20 (10 red and 10 white) under each of three illuminance levels (571, 1143 and 1714 lux). Balls were projected from a ball machine at 20 m s(-1) (45 mph) over a distance of 8.4 m, to the subject's dominant side. Catching performance was measured using an established catching scale. Movement initiation times for each hand were also calculated for each trial using a motion-analysis system. Data were submitted to separate two-way (ball colour [2] x illuminance level [3]) repeated measures analysis of variance. No significant effects were obtained for ball colour or illuminance levels for either catching performance or movement initiation time. Neither ball colour nor light level (within the range tested) affected slip-catching performance and movement initiation times in professional cricketers. Therefore it was concluded that the changes made to ball colour and light conditions in professional cricket were not detrimental to catching performance.
近年来，职业板球运动中的设备和技术发生了许多变化，包括在昼夜比赛中引入了白色球。在本研究中，研究了职业板球运动员在球的颜色和光照水平不同时的模拟滑倒接球表现和动作起始时间。五名男性职业板球运动员（平均年龄：27.3±1.4岁）自愿总共接住60个板球，在三种光照水平（571、1143和1714勒克斯）下各接住20个（10个红色和10个白色）。球从发球机以20米/秒（45英里/小时）的速度投射8.4米的距离，投向受试者的优势侧。使用既定的接球量表测量接球表现。每次试验还使用运动分析系统计算每只手的动作起始时间。数据提交给单独的双向（球的颜色[2]×光照水平[3]）重复测量方差分析。接球表现或动作起始时间在球的颜色或光照水平方面均未获得显著影响。球的颜色和光照水平（在所测试的范围内）均未影响职业板球运动员的滑倒接球表现和动作起始时间。因此得出结论，职业板球运动中球的颜色和光照条件的变化对接球表现无害。
