: In recent years, the study of the benefits that physical exercise has on brain health has acquired special relevance. In order to implement exercise as an intervention to protect the brain, it is important to have a more clear idea of its effect in the young population. However, few studies have been carried out on these ages. : The main objective of our study was to evaluate the association between physical activity (PA) with memory and executive function, in university students, analyzing the modulatory effect of sex. : We collected socio-demographic and life habit information, as well as data on the PA that was carried out during the previous week using the international PAquestionnaire short version (IPAQ-SF) questionnaire in 206 university students (mean age 19.55 ± 2.39; 67.5% women). Memory and executive function were assessed using a comprehensive battery of validate cognitive tests. Univariate and multivariate analyses were performed to correlate PA with cognitive tests scores and to evaluate the potential synergistic role of sex. : The main finding was that the total amount of PA correlated positively with several tests that evaluated aspects of executive function, specifically Stroop Colors (Pearson's = 0.17; = 0.01) and the Stroop Test Color-Word (Pearson's = 0.15. = 0.03). These results were adjusted by a large number of possible confounders and modifying variables in a multivariate analysis, like age, sex, academic record, day of the week, and time at which the test was performed. Additionally, we found out that sex had a synergistic effect with PA on the executive test Trail making test-A (TMTA), and in women, this association was stronger than in men. The more PA women reported, the better they performed, that is to say that they took less time to finalize the TMT-A (interaction term between PA and sex: = -0.0009; = 0.014). : Our study adds evidence of the benefit of PA in cognition in the young population, specifically in the executive inhibitory control, and more significantly in women.
近年来，体育锻炼对大脑健康益处的研究具有特殊意义。为了将锻炼作为一种保护大脑的干预措施来实施，更清楚地了解其对年轻人群的影响很重要。然而，针对这些年龄段的研究很少。
我们研究的主要目的是评估大学生身体活动（PA）与记忆和执行功能之间的关联，并分析性别调节作用。
我们收集了社会人口统计学和生活习惯信息，以及使用国际身体活动问卷简版（IPAQ-SF）对206名大学生（平均年龄19.55±2.39岁；67.5%为女性）前一周进行的身体活动数据。使用一系列经过验证的认知测试评估记忆和执行功能。进行单变量和多变量分析，以关联身体活动与认知测试分数，并评估性别的潜在协同作用。
主要发现是，身体活动总量与评估执行功能方面的多项测试呈正相关，特别是斯特鲁普颜色测试（Pearson相关系数 = 0.17；P = 0.01）和斯特鲁普色词测试（Pearson相关系数 = 0.15，P = 0.03）。在多变量分析中，这些结果通过大量可能的混杂因素和修正变量进行了调整，如年龄、性别、学业成绩、星期几以及测试进行的时间。此外，我们发现性别在执行测试连线测验A（TMTA）上与身体活动有协同作用，在女性中，这种关联比男性更强。女性报告的身体活动越多，表现越好，也就是说她们完成TMT-A所需的时间越少（身体活动与性别之间的交互项：β = -0.0009；P = 0.014）。
我们的研究增加了身体活动对年轻人群认知有益的证据，特别是在执行抑制控制方面，对女性更为显著。
