摘要

背景:研究表明,老年人的心肺功能(CRF)与执行功能之间存在正相关关系。虽然这种关系已经得到了很好的证实,但关于 CRF 和执行功能的性别差异作用的文献似乎还存在空白。本研究旨在通过对男性和女性进行分层研究,评估性别在老年人CRF和认知能力之间关系中的影响:96名老年人(61名女性)在知情的情况下书面同意参加这项横断面研究。所有参与者都在自行车测力计上接受了最大连续分级运动测试,以评估他们的最大摄氧量(VO2max),并接受了计算机化的 Stroop 任务(命名、抑制和转换),以评估他们的执行功能。根据 VO2max 测试结果和美国运动医学学会的指导原则,将女性和男性分为体能较好和体能较差两组。采用一般线性模型和估计边际均值进行分析:结果显示,男性和女性老年人在命名、抑制和转换性能测试中没有明显差异(P>0.05):根据观察到的 CRF 与执行功能之间的正相关关系,本研究的数据支持了这样一种观点,即有氧运动通常会增加 CRF,因此无论性别如何,有氧运动都能很好地改善老年人的执行功能。

Executive functions in male and female older adults with aligned levels of VO2max.

Background: Studies have shown a positive relationship between cardiorespiratory fitness (CRF) and executive functioning in older adults. Although this relationship has been well established, there seems to be a gap in the literature on the role of sex differences concerning CRF and executive functions. The current study aimed to assess the effect of sex in the relationship between CRF and cognition in older adults by stratifying the results to examine effects in males and females.

Methods: Ninety-six older adults (61 females) gave their written, informed consent to participate in this cross-sectional study. All participants underwent a maximal continuous graded exercise test on a cycle ergometer to assess their maximal oxygen uptake (VO2max) and a computerized Stroop task (naming, inhibition, and switching) to assess their executive functions. According to VO2max test results and the American College of Sports Medicine's guidelines, females and males were classified into higher-fit and lower-fit groups. A general linear model and estimated marginal means analyses were applied.

Results: Results showed no significant differences in the naming, inhibition and switching performance tests between male and female older adults (P>0.05).

Conclusions: Based on the observed positive relationship between CRF and executive functioning, the data of the current study supports the idea that aerobic exercise, which typically increases CRF, is well-situated to improve executive functioning in older adults, irrespective of sex.
