Abstract

Master athletes are a model of successful aging as their high level of physical activity limits the age-related change of physiological functions. This model is used to investigate how a high level of physical activity impacts cognitive functioning. We aim to study the effect of a high level of physical activity on the ability to manage interferences and binding processes in episodic encoding in an ecological situation. Fifty-five participants were recruited and separated into three groups: 18 master athletes (MA, M = 69.39, SD = 1.13 years), 18 young adults (YA, M = 22.44, SD = 1.10 years), and 19 older adults with a moderate level of physical activity (OA, M = 72.11, SD = 1.10 years). Participants performed an episodic memory task assessing binding processes by encoding under either full or divided attention using a virtual reality technique. After encoding under divided attention, MA outperformed OA in the interference task as well as in the binding score on both free and cued recall. After encoding under full attention, YA and MA did not differ in the number of events recalled in cued recall. Furthermore, significant correlations were found between weekly volume of physical activity and cognitive performance. Binding and interference management, and probably the hippocampus along with prefrontal areas, benefit the most from a sustained and regular physical activity in master athletes.

运动健将运动水平对情景记忆分裂注意和绑定过程的影响:一项虚拟现实研究。
优秀运动员是成功衰老的典范,因为他们高水平的身体活动限制了与年龄相关的生理功能变化。这个模型被用来研究高水平的体育活动如何影响认知功能。我们的目的是研究高水平的身体活动对生态环境下情景编码中干扰和结合过程管理能力的影响。55名参与者被分为三组:18名运动健将(MA, M = 69.39, SD = 1.13岁),18名青壮年(YA, M = 22.44, SD = 1.10岁)和19名中等体力活动水平的老年人(OA, M = 72.11, SD = 1.10岁)。参与者通过虚拟现实技术在完全注意力或分散注意力的情况下进行编码,来完成情景记忆任务,评估绑定过程。分散注意编码后,MA在干扰任务中优于OA,在自由回忆和提示回忆的结合得分上优于OA。在充分注意下编码后,YA和MA在线索回忆中回忆的事件数量上没有差异。此外,每周体力活动量与认知能力之间存在显著相关性。结合和干扰管理,可能是海马体和前额叶区域,从持续和有规律的体育锻炼中受益最大。

期刊介绍: Experimental Aging Research is a life span developmental and aging journal dealing with research on the aging process from a psychological and psychobiological perspective. It meets the need for a scholarly journal with refereed scientific papers dealing with age differences and age changes at any point in the adult life span. Areas of major focus include experimental psychology, neuropsychology, psychobiology, work research, ergonomics, and behavioral medicine. Original research, book reviews, monographs, and papers covering special topics are published.
