摘要
背景:在精英冰壶运动中,精确的时间感知、速度控制和准确性是成绩的关键组成部分。目的:本研究旨在调查频闪视觉条件对冰壶精英运动员关键表现方面的影响,以确定是否可以在长期训练中利用这些影响来提高冰壶精英运动员的表现:本研究涉及 32 名国家级男子冰壶运动员(n = 32,年龄:19.9 ± 2.2 岁,身高:178.0 ± 6.2 厘米,体重:71.9 ± 10.6 千克,训练年龄:2.7 ± 0.9 岁)。实验采用交叉对照法,参与者被随机分配到频闪优先组(16 人)或对照优先组(16 人)。每位参与者在频闪和正常视觉条件下完成测试,包括评估时间感知误差、速度控制误差和卷曲准确性。采用配对样本 t 检验分析不同条件下的成绩差异,采用双因素方差分析分析序列效应。如果主效应显著,则采用 Bonferroni 事后检验来比较差异。结果:在频闪条件下,参与者的时间感知错误增加(p < 0.001,Cohen's d = 1.143),速度控制传递错误增加(p = 0.016,Cohen's d = 0.448),准确性降低(p = 0.029,Cohen's d = 0.404)。序列主效应对速度控制错误的影响显著(p = 0.025,ηp2 = 0.081,Cohen's f = 0.297):结论:频闪视觉条件对精英冰壶运动中的认知(尤其是时间感知)和速度控制与准确性方面的传递性能产生了负面影响,突出了利用频闪训练提高精英冰壶运动性能的潜力和可行性。
The Impact of Stroboscopic Visual Conditions on the Performance of Elite Curling Athletes.
Background: In elite curling, precise time perception, speed control, and accuracy are critical components of performance. Stroboscopic training enhances visual processing speed, reaction time, motor skill control, and cognitive abilities by challenging the brain to make quick decisions with limited visual information.
Purpose: This study aimed to investigate the impact of stroboscopic visual conditions on the key performance aspects of elite athletes in curling to determine whether these effects can be leveraged in long-term training to enhance elite curling performance.
Methods: This study involved the participation of 32 national-level male curling athletes (n = 32, age: 19.9 ± 2.2 years, height: 178.0 ± 6.2 cm, body mass: 71.9 ± 10.6 kg, and training age: 2.7 ± 0.9 years). A cross-over controlled experiment was conducted, with participants randomly assigned to either a stroboscopic-first group (n = 16) or a control-first group (n = 16). Each participant completed tests under both stroboscopic and normal visual conditions, including assessments of time perception error, speed control error, and curling accuracy. Paired sample t-tests were employed to analyse performance differences across conditions, and two-factor ANOVA was used to analyse sequence effects. Bonferroni post-hoc tests were used to compare differences if the main effect was significant. Cohen's d was used for two-group comparisons, whereas ηp2 and Cohen's f were used for comparisons involving three or more groups.
Results: under stroboscopic conditions, participants experienced increased errors in time perception (p < 0.001, Cohen's d = 1.143), delivery speed control (p = 0.016, Cohen's d = 0.448), and reduced accuracy (p = 0.029, Cohen's d = 0.404). The sequence main effect on speed control error was significant (p = 0.025, ηp2 = 0.081, Cohen's f = 0.297).
Conclusions: Stroboscopic visual conditions negatively impacted cognition (especially time perception) and delivery performance focused on speed control and accuracy in elite curling, highlighting the potential and feasibility of using stroboscopic training to enhance elite curling performance.
