The Post-conditioning Acute Strength Exercise Facilitates Contextual Fear Memory Consolidation Via Hippocampal N-methyl-D-aspartate-receptors. Neuroscience 2023; 535:88-98. [PMID: 37925051 DOI: 10.1016/j.neuroscience.2023.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 10/18/2023] [Accepted: 10/20/2023] [Indexed: 11/06/2023]
Abstract
The benefits of aerobic exercises for memory are known, but studies of strength training on memory consolidation are still scarce. Exercise stimulates the release of metabolites and myokines that reaching the brain stimulate the activation of NMDA-receptors and associated pathways related to cognition and synaptic plasticity. The aim of the present study was to investigate whether the acute strength exercise could promote the consolidation of a weak memory. We also investigated whether the effects of strength exercise on memory consolidation and on the BDNF and synapsin I levels depends on the activation of NMDA-receptors. Male Wistar rats were submitted to strength exercise session after a weak training in contextual fear conditioning paradigm to investigate the induction of memory consolidation. To investigate the participation of NMDA-receptors animals were submitted to contextual fear training and strength exercise and infused with MK801 or saline immediately after exercise. To investigate the participation of NMDA-receptors in BDNF and synapsin I levels the animals were submitted to acute strength exercise and infused with MK801 or saline immediately after exercise (in absence of behavior experiment). Results showed that exercise induced the consolidation of a weak memory and this effect was dependent on the activation of NMDA-receptors. The hippocampal overexpression of BDNF and Synapsin I through exercise where NMDA-receptors dependent. Our findings showed that strength exercise strengthened fear memory consolidation and modulates the overexpression of BDNF and synapsin I through the activation of NMDA-receptors dependent signaling pathways.

Abstract
Exercise is a key component to health and wellness and is thought to play an important role in brain activity. Changes in brain activity after exercise have been observed through various neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). The precise impact of exercise on brain glucose metabolism (BGluM) is still unclear; however, results from PET studies seem to indicate an increase in regional metabolism in areas related to cognition and memory, direction, drive, motor functions, perception, and somatosensory areas in humans. Using PET and the glucose analog [18F]-Fluorodeoxyglucose (18F-FDG), we assessed the changes in BGluM between sedentary and chronic exercise in rats. Chronic treadmill exercise treatment demonstrated a significant increase in BGluM activity in the following brain regions: the caudate putamen (striatum), external capsule, internal capsule, deep cerebellar white matter, primary auditory cortex, forceps major of the corpus callosum, postsubiculum, subiculum transition area, and the central nucleus of the inferior colliculus. These brain regions are functionally associated with auditory processing, memory, motor function, and motivated behavior. Therefore, chronic daily treadmill running in rats stimulates BGluM in distinct brain regions. This identified functional circuit provides a map of brain regions for future molecular assessment which will help us understand the biomarkers involved in specific brain regions following exercise training, as this is critical in exploring the therapeutic potential of exercise in the treatment of neurodegenerative disease, traumatic brain injury, and addiction.

Abstract
Purpose Urine can sensitively reflect early pathophysiological changes in the body. The purpose of this study was to explore the changes of urine proteome in rats with regular swimming exercise. Methods In this study, experimental rats were subjected to daily moderate-intensity swimming exercise for 7 weeks. Urine samples were collected at weeks 2, 5, and 7 and were analyzed by using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Results Unsupervised clustering analysis of all urinary proteins identified at week 2 showed that the swimming group was distinctively different from the control group. Compared to the control group, a total of 112, 61 and 44 differential proteins were identified in the swimming group at weeks 2, 5 and 7, respectively. Randomized grouping statistical analysis showed that more than 85% of the differential proteins identified in this study were caused by swimming exercise rather than random allocation. According to the Human Protein Atlas, the differential proteins that have human orthologs were strongly expressed in the liver, kidney and intestine. Functional annotation analysis revealed that these differential proteins were involved in glucose metabolism and immunity-related pathways. Conclusion Our results revealed that the urinary proteome could reflect significant changes after regular swimming exercise. These findings may provide an approach to monitor the effects of exercise of the body.

Abstract
Increased energy food consumption during early-life has been associated with memory impairment. Swimming training has been reported to improve memory processes in rodent models. This study aimed to evaluate whether moderate-intensity swimming training counteracts learning and memory impairment in young mice fed a high-calorie diet during the early-life period. The contribution of hippocampal oxidative stress, as well as nuclear factor [erythroid-derived 2]-like 2/Kelch-like ECH-associated protein (NRF2/Keap-1/HO-1) and peroxisome proliferator-activated receptor gamma co-activator 1-alpha/mitochondrial transcription factor A (PCG-1α/mtTFA) signaling, in memory effects was also investigated. Three-week-old male Swiss mice received a high-calorie diet (20% fat; 20% carbohydrate enriched) or a standard diet from 21 to 49 postnatal days. Mice performed a moderate-intensity swimming protocol (5 days/week) and behavioral tests predictive of memory function. Mice fed a high-calorie diet and subjected to the swimming protocol performed better on short- and long-term spatial and object recognition memory tests than those fed a high-calorie diet. The swimming protocol modulated the hippocampal NRF2/Keap-1/HO-1 and mtTFA pathways in mice fed a high-calorie diet. Swimming training positively affected location and long-term memory, fat mass content, as well as NRF2/Keap-1/HO-1 and mtTFA proteins of control-diet-fed mice. In conclusion, a moderate-intensity swimming training evoked an adaptive response in mice fed a high-calorie diet by restoring different types of memory-impaired and hippocampal oxidative stress as well as upregulated the NRF2/Keap-1/HO-1 and mtTFA pathways.

Abstract
Objetivo: Investigar a relação entre o estresse crônico e a memória espacial em ratos. Metodologia:Utilizaram-se 20 ratos, machos, com 45 dias de vida, linhagem Wistar, divididos em 2 grupos: Estresse Choque (n = 10), onde foram alocados em uma caixa onde receberam um choque elétrico nas patas traseiras de 0,5 mA, por 2 s, a cada 30 s, por 5 min/dia, por 49 dias consecutivos; e Controle (n = 10), alocados na mesma caixa, porém sem receber estímulo, por 5 min, durante 49 dias. Posteriormente, iniciaram-se os procedimentos comportamentais, que consistiram na Habituação na Arena, Teste de Campo Aberto, Treino de Reconhecimento de Objetos, Teste de Memória de Curto Prazo (TMCP) e Teste de Memória de Longo Prazo (TMLP). Foram obtidas as taxas de duração de preferência exploratória. Os dados foram apresentados como média ± EPM. Resultados: No TMCP, o grupo Estresse Choque apresentou um aumento significativo da taxa de exploração (75,75 ± 4,77% vs 58,49 ± 4,83%; p = 0,023), demonstrando um efeito positivo do estresse crônico sobre a memória de curto prazo. No TMCP, não houve diferença significativa do grupo Estresse Choque (55,23 ± 8,33%) em relação ao Controle (71,61 ± 4,76%; p = 0,146). Conclusão: o estresse crônico revelou efeitos positivos sobre a memória de curto prazo no Teste de Reconhecimento de Objetos, quando comparado ao grupo de controle, porém não obteve efeitos significativos sobre a memória de longo prazo.

Abstract
We investigated the relation between swimming exercise and fear memory extinction. Rats that performed regular swimming exercise over 6 wk underwent fear conditioning. Twenty-eight days later, they were submitted to extinction tests. Swimming rats had enhanced extinction process throughout the 5 days of the extinction test compared with sedentary rats. This suggests that the swimming exercise accelerated the process of aversive memory extinction, reducing the expression of conditioned fear behavior. These results encourage further studies addressing the anxiolytic effects of exercise, with potential implications for anxiety disorders such as posttraumatic stress disorder. NEW & NOTEWORTHY We have shown that rats that performed regular swimming exercise over 6 wk had enhanced extinction process compared with sedentary animals. The swimming exercise may accelerate the process of aversive memory extinction, reducing the expression of conditioned fear behavior.

Abstract
BACKGROUND Emerging work demonstrates that acute exercise may enhance explicit memory function. No published systematic reviews have evaluated the totality of research examining the effects of exercise on implicit memory function, which was the purpose of this systematic review. METHODS Databases (PubMed, PsychInfo, and Sports Discus) were searched to evaluate animal and human experimental studies evaluating the effects of exercise on implicit memory function. RESULTS Among the 10 evaluated studies that met inclusionary criteria for this systematic review, 7 were conducted in animal models (rats or mice), with 3 utilizing human samples. Among the seven animal model studies, all employed a fear conditioning paradigm to evaluate implicit memory performance. All six animal studies employing a chronic exercise paradigm demonstrated evidence for associations between chronic exercise and enhanced fear conditioning. The one animal study evaluating a high-intensity acute bout of exercise showed that high-intensity acute exercise worsened implicit memory retrieval. Among the three human studies, one demonstrated a beneficial effect of acute exercise on implicit memory function. DISCUSSION There is consistent evidence in animal models that chronic exercise enhances implicit memory, as assessed by fear conditioning. However, there have been too few human studies investigating this topic to render any meaningful conclusions regarding the relationship between exercise and cognitive-based implicit memory among humans.
