The Association Of Self-Reported Physical Activity On Human Sensory Long-Term Potentiation, Damien Moore, Paul D. Loprinzi Jan 2021

The Association Of Self-Reported Physical Activity On Human Sensory Long-Term Potentiation, Damien Moore, Paul D. Loprinzi

Faculty and Student Publications

Exercise has been shown to enhance synaptic plasticity, therefore, potentially affecting memory. While the mechanism(s) responsible for this relationship have been explored in animal models, current research suggests that exercise may possess the ability to induce synaptic long-term potentiation (LTP). Most of the LTP mechanistic work has been conducted in animal models using invasive procedures. For that reason, the purpose of the present experiment was to investigate whether self-reported exercise is related to human sensory LTP-like responses. Nineteen participants (MAGE= 24 years; 52.6% male) completed the study. Long-term potentiation-like responses were measured by incorporating a non-invasive method that assess the …

Faculty and Student Publications

The specific questions addressed from this research include: (1) Does high-intensity acute exercise improve memory?, (2) If so, do the mechanisms occur via encoding, consolidation, or retrieval? and (3) If acute exercise occurs in multiple phases of memory (e.g., before encoding and during consolidation), does this have an additive effect on memory? Three experimental, within-subject, counterbalanced studies were conducted among young adults. High-intensity exercise involved a 20-minutes bout of exercise at 75% of heart rate reserve. Memory was evaluated from a word-list task, including multiple evaluations out to 24-hours post-encoding. The timing of the exercise and memory assessments were carefully …

Both acute exercise and learning are thought to influence memory via an LTP-related mechanism. Limited research has evaluated the individual and combined effects of acute exercise and learning strategy implementation (e.g., 3-R technique, cue-integration) on memory, which was the purpose of this study. Materials and Methods: For Experiment 1, participants (n = 80; Mage = 20.9 years) were randomized into one of four experimental groups, including Exercise + Learning (E + L), Learning …


The Endocannabinoid System As A Potential Mechanism Through Which Exercise Influences Episodic Memory Function, Paul D. Loprinzi, Liye Zou, Hong Li May 2019

The Endocannabinoid System As A Potential Mechanism Through Which Exercise Influences Episodic Memory Function, Paul D. Loprinzi, Liye Zou, Hong Li

Faculty and Student Publications

© 2019 by the authors. Emerging research demonstrates that exercise, including both acute and chronic exercise, may influence episodic memory function. To date, mechanistic explanations of this effect are often attributed to alterations in long-term potentiation, neurotrophic production, angiogenesis, and neurogenesis. Herein, we discuss a complementary mechanistic model, suggesting that the endocannabinoid system may, in part, influence the effects of exercise on memory function. We discuss the role of the endocannabinoid system on memory function as well as the effects of exercise on endocannabinoid alterations. This is an exciting line of inquiry that should help delineate new insights into the …

Physical Activity And Cognitive Function Among Older Adults With An Elevated Gamma Gap, Emily Frith, Paul D. Loprinzi

Faculty and Student Publications

© 2018 The Author(s) Published by S. Karger AG, Basel. Objective: An elevated gamma gap is indicative of high serum concentrations of globulin proteins, some of which elicit acute inflammatory responses. An impaired cognitive function has been linked to central and peripheral inflammation, while exercise is associated with protective, anti-inflammatory benefits. In this study, we evaluated whether the gamma gap is associated with cognitive function among older adults and whether physical activity is favorably associated with cognitive function among those with an elevated gamma gap. Materials and Methods: Data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES) were …


Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith Feb 2019

Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith

Faculty and Student Publications

© The Author(s) 2018. There is irrefutable evidence that regular participation in physical activity is favorably associated with numerous positive health outcomes, including cognitive function. Emerging work suggests that perceived physical activity, independent of actual physical activity behavior, is inversely associated with mortality risk. In this study, we evaluate whether perceived physical activity, independent of actual physical activity, is associated with cognitive function, a robust indicator of mortality risk. Data from the cross-sectional 1999–2002 National Health and Nutrition Examination Survey were employed (N = 2352; 60+ years of age). Actual physical activity was assessed via a validated survey. Perceived physical …
