“…It is suggested that exercising prior to a memory task may help to optimize memory encoding by increasing psychological-based attentional resources, inducing neuronal excitability in the neurocircuitry of the memory system, and, in turn, the enhancement of long-term potentiation, a key postulated mechanism of episodic memory function. This temporal effect of exercise is supported by recent work which shows that exercise during memory encoding is associated with diminished hippocampus-dependent memory [ 25 ]. Further, the prefrontal cortex and the hippocampus are important brain structures in binding information together [ 26 , 27 ], which is critical for the prevention of false memory creation.…”

Previous experimental work suggests that acute exercise may positively influence the accurate recall of past episodic events. However, few studies have examined whether acute exercise also reduces the number of false episodic memories. We evaluated this paradigm in conjunction with an examination of the temporal effects of acute exercise, which have previously been shown to play an important role in subserving episodic memory function. Twenty young adults participated in three experimental visits, including a non-exercise control visit, a visit involving an acute bout (20 min) of moderate-intensity exercise occurring prior to the memory task, and a visit involving an acute bout of exercise occurring during the encoding of the memory task. All visits were counterbalanced and occurred at least 24 h apart. The Deese–Roediger–McDermott (DRM) Paradigm, involving a separate word list trial for each visit, was employed to assess accurate and false episodic memory recall. For each visit, a short-term (immediate recall) and a long-term (25-min delay) memory recall was assessed. For both time points, the visit that involved exercise prior to encoding resulted in better short-term and long-term memory function (F(2) = 11.56, p < 0.001, η2p = 0.38). For both time points, the control visit resulted in a greater number of false memories. These findings suggest that acute moderate-intensity exercise may help to increase the accurate recall of past episodic memories and may help to reduce the rate of false memories.

“…While considerable advances in understanding the linkages between physical activity and memory have been made recently, attempts to explain the relationship will benefit from a wider selection of tests of memory than those currently populating the literature. Soga et al’s (2017) experiment exemplifies the strength of evaluating multiple types of memory and identifying dissociations in outcomes that conform to theoretical predictions. At a more elementary level, it will also be informative to examine closely the information-processing characteristic of memory tasks selected for experimentation.…”

“…Several experiments have focused on individual exercise bouts performed at intensities that promote aerobic metabolic energy production. A study conducted by Soga et al (2017) had young adults perform an ergometer cycling protocol during which individual participants pedaled for 5 min. The workload was then gradually increased to a target heart rate (60-70% HR maximum), which is considered moderate intensity aerobic exercise.…”

Bouts of exercise performed either prior to or immediately following study periods enhance encoding and learning. Empirical evidence supporting the benefits of interventions that simultaneously pair physical activity with material to be learned is not conclusive, however. A narrative, theory-based review of dual-task experiments evaluated studies in terms of arousal theories, attention theories, cognitive-energetic theories, and entrainment theories. The pattern of the results of these studies suggests that cognitive-motor interference can either impair or enhance memory of semantic information and the manner in which physical activity impacts working memory within executive processing appears to explain disparate outcomes. The integration and timing of physical movements in concert with the type of information to be encoded and remembered appears to be a critical requirement for learning. These observations have implications for the role of physical activity in education, rehabilitation, and gerontological settings.

“…When exercise occurs immediately before a memory encoding task, there are moderate enhancements to the volume of studied information correctly remembered, whereas exercising during encoding appears to impair encoding (see Loprinzi et al, 2019 , for a meta-analysis). Pre-encoding exercise is observed to be more beneficial than post-encoding exercise ( Labban and Etnier, 2011 ), whilst concurrent exercise and encoding may impair subsequent recall ( Soga et al, 2017 ). Furthermore, study characterizes in terms of exercise (intensity, duration), participants (age, fitness) and memory tasks (working memory, episodic memory, prospective memory) can moderate the potential for beneficial effects ( Loprinzi, 2018 ).…”

The Effects of Acute Moderate and High Intensity Exercise on Memory

et al. 2020

Acute cardiovascular exercise can enhance correct remembering but its impact upon false remembering is less clear. In two experiments, we investigated the effect of acute bouts of exercise on correct and false remembering using the Deese-Roediger-McDermott (DRM) memory test. In Experiment 1, healthy adults completed quiet rest or moderate intensity cycling prior to the memory test. In Experiment 2, a similar sample completed moderate intensity running, high intensity sprints, or a period of quiet rest prior to the memory test. In Experiment 1, acute moderate intensity exercise increased short-term correct, but not false, recall. Experiment 2 replicated these findings but also found an acute bout of high intensity exercise had no impact upon either type of shortterm recall. Acute moderate intensity exercise, but not acute high intensity exercise, can improve short-term correct recall without an accompanying increase in false recall potentially through processing of contextually specific information during encoding.
