    Abstract: Objective: There is suggestive evidence that exercise may have a greater effect on visuo-spatial memory, compared to other memory types. However, we have a limited understanding as to the mechanisms through which exercise may subserve visuo-spatial memory. Thus, the purpose of this review is to evaluate the extent to which exercise may influence visuo-spatial memory, whether exercise can attenuate drug- and diseased-induced declines in memory, and determine the underlying mechanisms of these relationships. Methods: We employed a systematic review approach. We identified studies using electronic databases, including PubMed, PsychInfo, Sports Discus and Google Scholar. Results: In total, we identified 32 articles. Among these, 2 were among humans and 30 were conducted in animal models. There was strong evidence sup- porting the facilitative role of chronic exercise in visuo-spatial memory improvements, as well as attenuation of drug- and diseased-induced memory decline. There are various mechanisms through which chronic exercise may influence visuo-spatial memory, including increased neuro-genesis, angiogenesis, improved neural efficiency, CB 1 receptor signaling, activation of H 2 receptors, and increased number of synaptic structures (eg, AMPA and NMDA receptors). Conclusion: Exercise may help to enhance visuo-spatial memory.

    Acute Exercise, Psychological Stress Induction, and Episodic Memory

    Abstract: Objective: In this study, we evaluated whether exercise prior to memory encoding or during memory consolidation can influence episodic memory function after being exposed to a stressful environment. Methods: We conducted 3 between-group randomized controlled experiments among young adults. We assessed episodic memory (via logic memory task) at the beginning of the experiment and approximately 45 minutes later. Across the 3 experiments, we varied the temporal period (eg, before memory encoding or during consolidation) of the acute bout of exercise (15-minute moderate-intensity exercise) and psychological stress induction. Results: Across all 3 experiments there was a statistically significant main effect for time for memory function, but there were no time x group interaction effects. Conclusion: Memory declined across the 2 assessment periods, but for all 3 experiments, exercise was not associated with memory function after being exposed to a stressful stimulus.

    Acute Exercise and Sustained Attention on Memory Function
    JCFCorp SG PTE LTD ; 2020

    Abstract: Objective: 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. Methods: 23 young adults (M age = 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. Results: Short-term memory performance was significantly greater than long-term memory, M diff = 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. Conclusion: Engaging in an acute bout of exercise before a sustained attention task additively influenced short-term memory function.
