Abstract：
BACKGROUND: The main purpose of this study was to determine the effects of a high-intensity interval training (HIIT) intervention in the context of moderate alcohol consumption on cognitive performance in healthy young adults.
METHODS: We conducted a 10-week HIIT program along with four types of beverages with/without alcohol content. A total of 75 healthy adults (18-40 years old; 46% female) were allocated to either a control Non-Training group or an HIIT program group (2 days/week). Using block randomization, participants in the HIIT group were further allocated to an HIIT-Alcohol group (alcohol beer or sparkling water with vodka added, 5.4%) or an HIIT-NonAlcohol group (sparkling water or non-alcohol beer, 0.0%). The control group was instructed to maintain an active lifestyle but did not undergo any regular training. A comprehensive neuropsychological battery was used to evaluate cognitive performance (i.e., memory, working memory, processing speed, inhibitory control, and verbal fluency). Changes from baseline to week 10 were included in the main analyses.
RESULTS: All groups improved in all neuropsychological measures (all p ≤ 0.001), independent of sex and alcohol consumption, with no statistical differences between groups (all p > 0.05). Furthermore, larger increases in maximal oxygen uptake were associated with greater improvements in processing speed, inhibitory control, and verbal fluency (all p < 0.050).
CONCLUSIONS: Although the improvements found in cognitive performance cannot be attributed to the HIIT intervention, no significant impairments in cognitive functions were noted due to moderate alcohol intake. Furthermore, our results confirmed that exercise-induced physical fitness improvements were associated with cognitive performance enhancements in young healthy adults.

摘要：
背景：这项研究的主要目的是确定在适度饮酒的背景下进行高强度间歇训练（HIIT）干预对健康年轻人认知能力的影响。
方法：我们进行了为期10周的HIIT计划以及四种有/没有酒精含量的饮料。总共75名健康成人(18-40岁;46%为女性)被分配到对照非训练组或HIIT计划组(2天/周)。使用块随机化，HIIT组的参与者被进一步分配到HIIT-酒精组（酒精啤酒或添加伏特加的苏打水，5.4％）或HIIT-非酒精组（起泡水或非酒精啤酒，0.0%）。对照组被指示保持积极的生活方式，但没有接受任何常规训练。一个全面的神经心理学电池被用来评估认知表现(即，记忆,工作记忆,处理速度,抑制控制，和口头流畅性)。从基线到第10周的变化包括在主要分析中。
结果：所有组的所有神经心理学指标均得到改善（均p≤0.001），与性和饮酒无关，组间无统计学差异(均P>0.05)。此外，最大摄氧量的增加与处理速度的提高有关，抑制控制，和语言流畅性（所有p<0.050）。
结论：尽管认知表现的改善不能归因于HIIT干预，未发现因适度饮酒导致的认知功能显著受损.此外，我们的研究结果证实,在年轻健康成人中,运动引起的身体素质改善与认知能力增强相关.
