Physical inactivity significantly increases risk of cardiovascular diseases, which are highly prevalent in aging. Conversely, higher levels of physical activity in aging have been associated with benefits for physical and cognitive health and is hypothesized to prevent and reduce development of cardiovascular risk factors. However, those older adults with the highest activity levels (i.e., Master Athletes [MA]) are relatively understudied, and even fewer studies involve female MA.
The aim of this study was to compare the physiological, physical, and cognitive profiles of an 83-year-old track-and-field MA runner to a sample of inactive age-matched females.
Results revealed the MA had a high peak oxygen uptake and had superior performance on visuospatial memory tasks compared to her inactive counterparts. Cerebral blood flow was slightly elevated in the MA, but lower cerebrovascular reactivity was revealed compared to the other female included in the magnetic resonance imaging portion.
Our results suggest that high levels of physical activity have benefits on multiple aspects of an aging female's life and that more studies should include MA, as well as a spectrum of cardiorespiratory fitness to further understand the role of physical activity in female aging.
身体活动不足会显著增加心血管疾病的风险,而心血管疾病在老龄化人群中极为普遍。相反,老年人身体活动水平较高与身体健康和认知健康的益处相关,并被假设可以预防和减少心血管危险因素的发展。然而,那些身体活动水平最高的老年人(即,大师运动员[MA])相对研究较少,涉及女性 MA 的研究更少。
本研究的目的是比较一位 83 岁田径 MA 跑步者与一组不活跃的同龄女性的生理、身体和认知特征。
结果表明,MA 的峰值摄氧量较高,在视空间记忆任务上的表现优于不活跃的同龄人。与磁共振成像部分中包括的其他女性相比,MA 的脑血流略有升高,但脑血管反应性较低。
我们的结果表明,高水平的身体活动对女性衰老的多个方面都有好处,应该有更多的研究包括 MA 以及一系列心肺健康状况,以进一步了解身体活动在女性衰老中的作用。
