“…An additional reason for our null findings may be that our chosen exercise intensity (high-intensity) was not optimal for enhancing memory. In conflicting past research, some studies suggested that high-intensity acute exercise may be more effective in enhancing memory while others found moderate-intensity acute exercise optimal (Pyke et al, 2020). Lastly, it remains possible that acute exercise has no causal effect on human memory beyond improved incidental encoding, as in our study.…”

The present experiment evaluated the effects of self-reported exercise behavior and an acute bout of high-intensity exercise on explicit memory function. The memory tasks were encoded either incidentally or intentionally; for intentional encoding, participants were told to focus on memorizing the stimuli (words), whereas for incidental encoding, participants were unaware that they would be subsequently asked to complete an object recognition task. Among a sample of 150 adults (Mage = 20 years), randomly assigned experimental participants engaged in the following task sequence: (a) incidentally encoded a series of objects, (b) engaged in 20 minutes of high-intensity exercise, (c) intentionally encoded a word list, and (d) completed explicit memory retrieval tasks. Control group participants viewed a time matched video in lieu of high intensity exercise. We measured self-reported exercise behavior via an exercise questionnaire. We did not observe convincing evidence of an effect of high-intensity acute exercise, when occurring during the early consolidation period, on memory function, for either incidental or intentional encoding tasks. However, self-reported engagement in moderate-to-vigorous physical activity was favorably associated with explicit memory performance.

“…Another aspect that should be carefully considered in future work is the intensity of acute exercise. Based on meta-analytic findings [20], we intentionally chose a higher intensity bout of exercise, but recent work suggests that moderate-intensity exercise may optimally influence memory [26]. Given these conflicting findings, future work should consider evaluating intensity-specific effects of acute exercise on face-name memory.…”

The majority of previous research evaluating the effects of acute exercise on episodic memory function have focused on explicit memory tasks involving word-list paradigms. For a more real-world application, the present experiment evaluates whether high-intensity acute exercise can improve episodic memory function of incidentally processed information as well as increase one's ability to remember names associated with faces (face-name paradigm). A two-arm, parallel-group, randomized controlled intervention was employed. Participants (N = 91; M age = 20 years) were randomized into one of two groups, including an experimental group and a control group. The experimental group exercised for 20 min on a treadmill at a high-intensity (75% of heart rate reserve), while the control group engaged in a seated, time-matched task. Explicit memory was assessed from an intentional processing face-name paradigm in which participants encoded and subsequently recalled names that were paired with faces. Episodic memory for incidentally processed information was evaluated with a computerized program involving spatial-temporal integration. The mean (SD) number of correctly recalled face-name pairs between the exercise and control groups, respectively, for immediate memory were 11.16 (4.4) and 9.79 (4.3), P > 0.05. Results were similar for incidentally processed information, in that there were no differences between the exercise [7.30 (1.7)] and control [7.52 (1.9)] groups, P > 0.05. Overall, we did not observe evidence that high-intensity acute exercise improves episodic memory for incidentally or intentionally processed information.

“…Other authors found opposite conclusions by showing higher benefits of an acute MICT session on memory performance than HIIT [117]. A meta-analysis by Chang et al (2012) showed that lower intensities would better improve cognitive performance immediately after an acute exercise completion (until 1 min) [118].…”

Stroke-induced cognitive impairments affect the long-term quality of life. High-intensity interval training (HIIT) is now considered a promising strategy to enhance cognitive functions. This review is designed to examine the role of HIIT in promoting neuroplasticity processes and/or cognitive functions after stroke. The various methodological limitations related to the clinical relevance of studies on the exercise recommendations in individuals with stroke are first discussed. Then, the relevance of HIIT in improving neurotrophic factors expression, neurogenesis and synaptic plasticity is debated in both stroke and healthy individuals (humans and rodents). Moreover, HIIT may have a preventive role on stroke severity, as found in rodents. The potential role of HIIT in stroke rehabilitation is reinforced by findings showing its powerful neurogenic effect that might potentiate cognitive benefits induced by cognitive tasks. In addition, the clinical role of neuroplasticity observed in each hemisphere needs to be clarified by coupling more frequently to cellular/molecular measurements and behavioral testing.
