Sustained attention is critical for various activities of daily living, including engaging in health-enhancing behaviors and inhibition of health compromising behaviors. Sustained attention activates neural networks involved in episodic memory function, a critical cognition for healthy living. Acute exercise has been shown to activate these same neural networks. Thus, it is plausible that engaging in a sustained attention task and engaging in a bout of acute exercise may have an additive effect in enhancing memory function, which was the purpose of this experiment. 23 young adults (M = 20.7 years) completed 2 visits, with each visit occurring approximately 24 hours apart, in a counterbalanced order, including: (1) acute exercise with sustained attention, and (2) sustained attention only. Memory was assessed using a word-list paradigm and included a short- and long-term memory assessment. Sustained attention was induced via a sustained attention to response task (SART). Acute exercise involved a 15-minute bout of moderate-intensity exercise. Short-term memory performance was significantly greater than long-term memory, M = 1.86, p < .001, and short-term memory for Exercise with Sustained Attention was significantly greater than short-term memory for Sustained Attention Only, Mdiff = 1.50, p = .01. Engaging in an acute bout of exercise before a sustained attention task additively influenced short-term memory function.
持续注意力对于日常生活中的各种活动至关重要，包括参与增进健康的行为以及抑制危害健康的行为。持续注意力会激活参与情景记忆功能的神经网络，而情景记忆功能是健康生活的一项关键认知。急性运动已被证明能激活这些相同的神经网络。因此，进行持续注意力任务和进行一轮急性运动可能在增强记忆功能方面具有累加效应，这正是本实验的目的。23名年轻成年人（平均年龄M = 20.7岁）以平衡的顺序完成了2次就诊，每次就诊间隔约24小时，包括：（1）急性运动与持续注意力相结合，以及（2）仅进行持续注意力任务。使用单词列表范式评估记忆，包括短期和长期记忆评估。通过持续注意力反应任务（SART）诱导持续注意力。急性运动包括15分钟的中等强度运动。短期记忆表现显著优于长期记忆，M = 1.86，p <.001，且急性运动与持续注意力相结合时的短期记忆显著优于仅进行持续注意力任务时的短期记忆，M差值 = 1.50，p = .01。在持续注意力任务之前进行一轮急性运动对短期记忆功能有累加影响。
