“…Acute and chronic exercise have been shown to enhance episodic memory [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Notably, however, as we have demonstrated in a recent systematic review [20], there may be an intensity-specific effect of acute exercise on enhancing episodic memory, with higher-intensity exercise potentially being optimal.…”

The improvement of memory performance is an ever-growing interest in research, with implications in many fields. Thus, identifying strategies to enhance memory and attenuate memory interference is of great public health and personal interest. The objective of this paper was to evaluate the role of intensity-specific acute exercise on improving paired-associative memory function and attenuating memory interference. A counterbalanced, randomized controlled, within-subject experimental design was employed. The three counterbalanced visits included a control visit, moderate-intensity exercise (50% of HRR; heart rate reserve) and vigorous-intensity exercise (80% of HRR), all of which occurred prior to the memory assessment. To evaluate memory interference, an AB/AC paired-associative task was implemented for each laboratory visit. The number of correctly recalled words from List 1 (AB–DE) was statistically significantly (F = 4.63, p = 0.01, η2p = 0.205) higher for the vigorous-intensity condition (M = 6.53, SD = 1.54) as compared to moderate-intensity (M = 6.11, SD = 1.59) and control (M = 5.00, SD = 2.56) conditions. No statistical significance was found between proactive interference or retroactive interference across the experimental conditions. This experiment provides evidence for an intensity-specific effect of acute exercise on short-term, paired-associative memory, but not memory interference.

“…The motivation for the present paper was a result of: 1) prior work demonstrating beneficial effects of exercise on cognitive function [1][2][3][4], 2) emerging work demonstrating beneficial effects of aquatic exercise on psychological well-being [18][19], and 3) the implications (e.g., feasibility, less weight-bearing) of aquatic exercise for health promotion purposes. The main finding of the present review was that, chronic aquatic exercise training appears to be effective in enhancing various biomarkers and cognitive outcomes.…”

The objective of this brief systematic review was to examine the effects of aquatic exercise on cognitive function. Studies were identified using electronic databases, including PubMed, PsychInfo, Sports Discus and Google Scholar. In total, 13 articles met the inclusionary criteria. Among the 13 studies, all 13 demonstrated beneficial cognitive effects from exercise. This included chronic aquatic exercise-induced improvements in global cognition, executive function, attention, learning and memory, cognitively-related biomarkers (e.g., BDNF) and cerebral oxygenation. For the two acute aquatic studies, listening errors, via an auditory vigilance task, was reduced when participants were emerged in chest-deep water, when compared to on land. These beneficial effects appear to occur across multiple populations, including children, adolescents, young adults and older adults with various conditions, such as Multiple Sclerosis, Alzheimer's disease, and fibromyalgia.

“…Recent work demonstrates that acute and chronic exercise may subserve episodic memory function [7][8][9][10][11][12][13][14][15][16]. Regarding acute exercise, the timing of the bout of exercise plays a critical role in influencing episodic memory performance [17].…”

Objective: The objective of this paper was to evaluate the extent to which exercise may influence long-term potentiation (LTP), a key cellular correlate of episodic memory function. Methods: Studies were identified using electronic databases, including PubMed, PsychInfo, Sports Discus and Google Scholar. Results: The computerized searches revealed 20 articles meeting the study criteria. Among these 20 evaluated articles, 17 were conducted in an animal model and 3 among humans. All 17 of these studies, with the exception of one, provided evidence that exercise enhances LTP. Each of the three human studies demonstrated evidence that exercise was favorably associated with LTP or LTP-like mechanisms. In animal models, exercise reliability increases LTP and lowers the threshold for LTP induction. Conclusion: Chronic exercise appears to robustly enhance LTP. The mechanisms of this effect are multifold and include, for example, exercise modulation of the structure and function of NMDA receptors.
