大学生宜人性与运动后急性心血管反应的关联

Association between Agreeableness and Acute Cardiovascular Reactivity after Exercise in College Students

摘要: 目的：探讨大学生宜人性与急性运动诱发心血管反应之间的关系。方法：以308名大学生为研究对象，采用大五人格简式量表(BFI-2-S)测量人格特质，通过2分钟深蹲任务诱发心血管反应，采用多变量贝叶斯模型分析收缩压变化(ΔSBP)、舒张压变化(ΔDBP)及心率变化(ΔHR)。结果：宜人性在各心血管指标上均呈负向趋势，但效应量较小，且95%可信区间均跨越零。基线舒张压对运动后舒张压具有较强预测作用，但未观察到明确的交互效应。收缩压与舒张压呈中等相关，而心率相对独立。结论：本研究提供了宜人性可能与较低心血管反应相关的初步证据，但当前结果仍存在较高不确定性，尚需更大样本研究进一步验证。

Abstract: Objective: To examine the association between agreeableness and acute exercise-induced cardiovascular reactivity in college students. Methods: A total of 308 students completed the Big Five Inventory-2 Short Form (BFI-2-S). Cardiovascular reactivity was induced using a 2-minute squat task, and changes in systolic blood pressure (ΔSBP), diastolic blood pressure (ΔDBP), and heart rate (ΔHR) were analyzed using a multivariate Bayesian model. Results: Agreeableness showed negative trends across all cardiovascular indices, but the effect sizes were small and all 95% credible intervals included zero. Baseline diastolic blood pressure strongly predicted post-exercise diastolic blood pressure, whereas no clear interaction effect was observed. Systolic and diastolic blood pressure were moderately correlated, while heart rate was relatively independent. Conclusions: The present study provides preliminary evidence suggesting that agreeableness may be associated with lower cardiovascular reactivity; however, substantial uncertainty remains, and larger studies are needed to further verify these findings.
