Although prolonged training with stroboscopic eyewear has demonstrated potential for enhancing visuomotor skills, the acute effects of stroboscopic stimulation are not well understood. The aim of the study was to investigate the short-term effects of stroboscopic exposure during the ball-specific phase of soccer warm-up on agility performance in preplanned and unpredictable (RA) tasks. Also, these effects were examined both in tasks involving ball dribbling and without the ball, as well as under fatigued and non-fatigued conditions. Twenty-two male soccer players participated in three sessions: a familiarization session and two experimental sessions, one with and one without stroboscopic exposure during the warm-up. RA was assessed before and after each session using the 10-repetition Illinois Agility Test, with and without ball control. Results showed that stroboscopic exposure significantly enhanced RA performance in tasks involving ball dribbling (p < 0.001, effect size (ES) = 0.57), and these effects were maintained under fatigued conditions (p = 0.007, ES = 0.39). However, there were no significant improvements in RA without the ball (p > 0.05). Exercise-induced fatigue reduced RA performance in both conditions (F = 28.2; p < 0.001), regardless of warm-up type (F = 0.5; p = 0.484). Additionally, stroboscopic exposure did not significantly affect the changes of direction speed performance in the Illinois Agility Test (F = 0.5; p = 0.479). These findings suggest that integrating stroboscopic eyewear into the ball-specific phase of soccer warm-ups effectively improves RA performance in tasks involving dribbling under both non-fatigued and fatigued conditions. The effectiveness of acute stroboscopic stimulation is closely related to the specificity of the tasks in which it is applied. These insights could benefit training across various sports, encouraging coaches to adopt this approach to enhance player preparation before both training and competitions.
尽管使用频闪眼镜进行长时间训练已显示出增强视觉运动技能的潜力，但频闪刺激的急性效应尚未得到充分理解。本研究的目的是调查在足球热身的特定球类阶段进行频闪暴露对预先计划和不可预测（RA）任务中的敏捷性能的短期影响。此外，在涉及运球和不涉及球的任务中，以及在疲劳和非疲劳条件下，均对这些影响进行了检查。22名男性足球运动员参加了三个阶段：一个熟悉阶段和两个实验阶段，其中一个实验阶段在热身期间进行频闪暴露，另一个则不进行。在每个阶段前后，使用10次重复的伊利诺伊敏捷性测试评估RA，包括有球控制和无球控制。结果表明，频闪暴露显著提高了涉及运球任务中的RA性能（p < 0.001，效应大小（ES） = 0.57），并且这些效应在疲劳条件下得以维持（p = 0.007，ES = 0.39）。然而，无球情况下的RA没有显著改善（p > 0.05）。运动诱发的疲劳在两种条件下均降低了RA性能（F = 28.2；p < 0.001），无论热身类型如何（F = 0.5；p = 0.484）。此外，频闪暴露对伊利诺伊敏捷性测试中的变向速度性能变化没有显著影响（F = 0.5；p = 0.479）。这些发现表明，将频闪眼镜纳入足球热身的特定球类阶段可有效提高在非疲劳和疲劳条件下涉及运球任务中的RA性能。急性频闪刺激的有效性与应用该刺激的任务的特异性密切相关。这些见解可能有益于各种运动项目的训练，鼓励教练采用这种方法来提高运动员在训练和比赛前的准备水平。
