Acute exercise has been shown to transiently improve specific aspects of cognitive function, however the mechanism governing these effects remain unclear. Blood pressure responses during exercise have been hypothesized to be a primary contributing factor, in part through its influence on cerebral blood flow. In this counterpoint, we highlight the inconsistent and weak associations between changes in blood pressure, cerebral blood flow and cognitive responses during and following acute exercise. Despite sound theoretical foundation, cognitive responses to exercise do not appear strongly related to blood pressure and more likely stem from a complex integration of multiple mechanisms.
急性运动已被证明可短暂改善认知功能的特定方面，但控制这些影响的机制仍不清楚。运动期间的血压反应被假设是一个主要的促成因素，部分原因是它对脑血流的影响。在这篇反驳文章中，我们强调了在急性运动期间和之后，血压、脑血流和认知反应之间变化的不一致和微弱关联。尽管有合理的理论基础，但运动对认知的反应似乎与血压没有很强的关系，而更可能源于多种机制的复杂整合。
