Effect of Acute Intermittent Exercise on Cognitive Flexibility: the Role of Exercise Intensity

A Neurovisceral Integrative Study on Cognition, Heart Rate Variability, and Fitness in the Elderly

“…Specifically, we demonstrated that working memory is associated with the performance in the 6-min walk and TUG tests, which are reliable indicators of aerobic capacity and dynamic balance in the elderly (Figure 1). These results are in agreement with other studies that showed a direct correlation between aerobic capacity and performance on tasks relying on executive functions (Kramer and Erickson, 2007;Alderman and Olson, 2014;Dupuy et al, 2015Dupuy et al, , 2018. Hansen et al (2004) found that after a period of 8 weeks of aerobic training individuals not only improved performance on cognitive tasks (working memory, sustained and selective attention), but that this result was accompanied by improvements in HRV.…”

“…Electrophysiological and neuroimaging studies have provided evidence that cardiorespiratory fitness is positively correlated with brain function, particularly in brain regions associated with the CAN, which has shown increased neuroplasticity after physical exercise interventions, improving both cardiovascular and cognitive control (Gomez-Pinilla and Hillman, 2013). However, relatively few studies have focused on the relationship between physical fitness and effects on NVI biomarkers such as HRV, particularly in the elderly (see Albinet et al, 2010Albinet et al, , 2016Dupuy et al, 2018). While Alderman and Olson (2014) demonstrated the role of physical fitness in improving autonomic and neurocognitive health in young adults, these authors failed to show HRV-mediated influences between cardiorespiratory fitness and cognitive performance, suggesting that other mediators may be more relevant in this population, which is at the apex of cognitive performance and with not much individual difference in cardiorespiratory fitness, compared to the elderly.…”

Impact of Carbohydrate Ingestion on Cognitive Flexibility and Cerebral Oxygenation during High-Intensity Intermittent Exercise: A Comparison between Maple Products and Usual Carbohydrate Solutions

“…During the third visit, participants performed a computerized version of the Stroop Color Word Test with the measurement of cerebral oxygenation before, during (recovery intervals), and at 15 and 30 min after HIIE. This procedure was presented in a previous study [28]. The perceived difficulty of the cognitive task was systematically measured with the DP-15 scale [29,30] following each cognitive assessment.…”

Editorial Special Topic: Enhancing Brain and Cognition via Physical Exercise

“…Peven et al (2018) showed that moderate-to-vigorous physical activity in bouts < 10 min in duration may have significant cognitive benefits in older adults. Dupuy et al (2018) demonstrated that both moderate-and high-intensity exercise enhance cognitive performance during and following acute intermittent exercise.…”

“…Peven et al (2018) showed that moderate-to-vigorous physical activity in bouts < 10 min in duration may have significant cognitive benefits in older adults. Dupuy et al (2018) demonstrated that both moderate-and high-intensity exercise enhance cognitive performance during and following acute intermittent exercise.ten Brinke et al (2018) revealed that a 6-month aerobic training program may promote cognitive outcomes in older adults with mild subcortical ischemic vascular cognitive impairment by improving aerobic fitness capacity and maintaining cortical thickness. Raine et al (2018), relying on a large aggregated dataset, demonstrated that aerobic fitness in childhood may be particularly beneficial to the allocation of attentional resources, as indexed by P3 amplitude as well as response accuracy and intra-individual variability.…”
