摘要
简介:赛车是一项对身体和认知都要求很高的运动,需要在极端条件下快速做出决策。虽然已经探索了身体训练和补水策略,但很少有研究调查营养干预以提高认知或驾驶表现。本研究考察了西洋参提取物Cereboost对专业赛车手的情绪、认知功能和模拟驾驶表现的影响。方法:58名有执照的司机完成了一项四阶段的受试者方案(基线、急性、慢性和急性对慢性),涉及200毫克/天的Cereboost补充。评估包括经过验证的情绪问卷,通过Senaptec感官站进行的认知测试(空间记忆和分散注意力),以及在专业级赛车模拟器中进行30分钟的训练。统计分析包括方差分析和Holm-Bonferroni校正。结果:经多重比较校正后,Cereboost对情绪和认知功能的影响无统计学意义。然而,急性-慢性补充显著提高了模拟驾驶性能,单圈时间缩短了3秒,在弯道时加速油门(调整后P = 0.000003, Cohen’s d = -1.274)。参与者报告了主观的精神敏锐度(97%)和驾驶表现(94%)的改善。结论:虽然Cereboost没有显著改变情绪或认知测试结果,但持续补充可以提高专业驾驶员的模拟驾驶表现。这些发现表明益智补充剂对赛车运动表现的潜在益处,值得在赛道上进行进一步的研究。
The influence of cereboost on mood, cognitive function, and simulated driving in professional race car drivers.
Introduction: Race car driving is a physically and cognitively demanding sport requiring rapid decision-making under extreme conditions. While physical training and hydration strategies have been explored, few studies have investigated nutritional interventions to enhance cognitive or driving performance. This study examined the effects of Cereboost, an American Ginseng extract, on mood, cognitive function, and simulated driving performance in professional race car drivers.
Methods: Fifty-eight licensed drivers completed a four-phase, within-subjects protocol (baseline, acute, chronic, and acute-on-chronic) involving 200 mg/day Cereboost supplementation. Assessments included validated mood questionnaires, cognitive testing via the Senaptec Sensory Station (spatial memory and split attention), and 30-minute sessions in a professional-grade racing simulator. Statistical analyses included ANOVA with Holm-Bonferroni corrections.
Results: Cereboost had no statistically significant effects on mood or cognitive function after correction for multiple comparisons. However, acute-on-chronic supplementation significantly improved simulated driving performance, with a 3-second reduction in lap time and faster throttle application in corners (adjusted P = 0.000003, Cohen's d = -1.274). Participants reported subjective improvements in mental acuity (97%) and driving performance (94%).
Conclusion: While Cereboost did not significantly alter mood or cognitive test outcomes, sustained supplementation enhanced simulated driving performance in professional drivers. These findings suggest potential benefits of nootropic supplementation for motorsport performance, warranting further investigation in on-track settings.
