Exercise types and working memory components during development

Characteristics of positive and negative networks in working memory task of basketball athletes

Working memory (WM) plays a vital role in athletic performance in open-skill sports like basketball. However, sport-induced WM adaptation is complex, and the underlying neural mechanisms remain poorly characterized. Using an N-back task with fMRI, this study investigated the brain function of 55 basketball athletes and 55 gender- and age-matched healthy controls during the WM tasks. The results revealed that basketball athletes showed increased activation in the task-positive network (TPN), reduced inhibitory activation in the default mode network (DMN), and cerebellar-mediated new dynamic between the two networks. These neural adaptations aligned with accelerated response speed at the cost of reduced 2-back accuracy, reflecting a speed-accuracy trade-off optimized for sport-specific demands. Future research should explore interventions targeting DMN regulation alongside TPN engagement to optimize cognitive performance in athletes. By bridging sports neuroscience and cognitive training paradigms, this study offers new insights into how sports training sculpts the brain's functional architecture.

The impact of sports participation, spontaneous sports, and motivational factors on the physical fitness of university students in Fuzhou

BACKGROUND

This study seeks to propose and empirically test a conceptual model that elucidates the complex interrelationships among sports participation, spontaneous sports, sports motivation, lifelong sports, and physical fitness among university students in Fuzhou. While the existing literature has examined various facets of physical activity and fitness, there is a notable paucity of research that simultaneously explores the influence of both spontaneous sports engagement and sports motivation on physical fitness, particularly within the context of university students in China. This gap in the literature highlights the pressing need for a nuanced empirical investigation to better understand how these factors interact and contribute to the promotion of lifelong sports and enhanced fitness outcomes.

METHODS

A systematic stratified sampling method was used to collect data from 400 university students across 18 undergraduate institutions in Fuzhou. The collected survey data were analyzed using Structural Equation Modeling (SEM).

RESULTS

Sports participation (β = 0.32, p < 0.001) and spontaneous sports engagement (β = 0.21, p < 0.001) demonstrated a significant positive influence on the physical fitness of university students. Moreover, sports participation (β = 0.43, p < 0.001) was a strong predictor of sustained physical activity levels among this group. In addition, sports participation (β = 0.47, p < 0.001) fostered spontaneous sports behaviors in university students, with spontaneous sports acting as a mediating variable in the relationship between sports participation and physical fitness. Furthermore, sports motivation played a crucial moderating role in the relationship between sports participation and spontaneous sports behaviors among university students.

CONCLUSION

The SEM results of this study support the proposed model, which explains the interrelationships among sports participation, spontaneous sports, Sports Motivation, and physical fitness. These findings highlight the importance of incorporating spontaneous sports and verbal motivation mechanisms into sports participation interventions to enhance physical fitness. The results of this study contribute to the development of more effective health and exercise programs for university students in Fuzhou to improve their physical fitness.

Physical-intellectual badminton teaching intervention for children with intellectual disabilities

Objective

To promote the healthy development of adolescents with intellectual disabilities, this study uses badminton to combine sports intervention with cognitive intervention to explore the content of sports teaching and cognitive intervention programs suitable for the learning of students with intellectual disabilities.

Methods

This research selected 26 mildly mentally disabled students in special education schools (age: 14.5 ± 0.8 years old), the subjects were randomly assigned to three groups by the digital randomization method, which badminton physical intelligence group (BSI), badminton group (BS) and control group (CON), with BSI conducting "physical intelligence" integration badminton intervention, and BS conducting badminton intervention, the intervention cycle was 12 weeks, with 3 teaching sessions per week, each session lasted for 40 min. The subjects' cognitive abilities and basic motor skills were analyzed.

Results

The results showed that BSI had highly significant differences in all cognitive ability test items (p < 0.01); BS had significant differences only in visual attention, visual memory, and motor imitation (p < 0.05). The results of incremental changes between groups before and after the intervention showed that BSI compared with CON had significant differences in all aspects except in object constancy (p < 0.05); BS compared with CON had higher incremental means than CON in visual attention, visual memory, and movement imitation, with significant differences (p < 0.05); BSI compared with BS had significant differences in all aspects except in object constancy and visual memory aspects, there is a significant difference (p < 0.05).

Conclusion

The "Body-Smart Integration" badminton intervention can improve the cognitive ability of students with intellectual disabilities in visual, auditory, imitation, concept learning, object permanence, etc., and the effect of improving the cognitive ability of students with intellectual disabilities is better than that of the badminton group and the control group.

Cardiorespiratory Fitness and Neurophysiological Indices of Working Memory Maintenance in Young Adults

Working memory is a crucial component of cognitive performance, supporting well-being, mental health, and successful personal and academic endeavors. Working memory performance and capacity peak during young adulthood, a critical period for managing increased life challenges. Emerging evidence indicates that cardiorespiratory fitness holds potential to enhance working memory performance; however, the underlying mechanisms remain unclear. This study examined the association between cardiorespiratory fitness and neurophysiological markers of cognitive control during a task requiring working memory maintenance. Young healthy adults (N = 112) completed a submaximal ergometer test to estimate cardiorespiratory fitness. Working memory maintenance was assessed using the Sternberg task under low and high cognitive loads, while event-related potentials (ERP) components (cue-P300, CNV, and probe-P300) were recorded. In addition, an immediate free recall task was administered. Path analysis revealed that higher cardiorespiratory fitness was significantly associated with better accuracy in the Sternberg task exclusively under high cognitive load (β = 0.21, p = 0.03). In the high load condition, higher negativity of the contingent negative variation (CNV) amplitude was significantly associated with higher fitness levels (β = -0.20, p = 0.03) and with better performance on the immediate free recall task (β = -0.23, p = 0.02), suggesting enhanced neurophysiological preparatory processes and dominance of proactive cognitive control strategy in fitter individuals. Cue-P300 and probe-P300 did not show significant associations with cardiorespiratory fitness nor working memory performance. These findings underscore the role of proactive cognitive control in mediating the benefits of cardiorespiratory fitness on cognitive performance.

The regular effects of concurrent aerobic and resistance exercise on global cognition in healthy elderly populations: A systematic review with meta-analysis of randomized trials

Aerobic and resistance exercises are widely recognized as essential for preserving and enhancing cognitive function. However, the effects of concurrent exercise on cognition in older adults remain unclear. This systematic review sought to evaluate the regular effects of concurrent aerobic and resistance training on global cognition in healthy older adults. A comprehensive search was conducted across PubMed, Web of Science, EMBASE, Google Scholar, Cochrane Library, and CNKI up to July 2024. Randomized controlled trials involving healthy older adults aged ≥65 years that assessed the cognitive effects of concurrent exercise were included. The methodological quality of the included studies was evaluated using the PEDro scale. Meta-analyses were performed using a random-effects model, and heterogeneity was quantified with the I2 statistic. The initial search identified 13,533 records, ultimately including 12 studies in the meta-analysis, which involved 2557 participants. The meta-analysis revealed non-significant effects of concurrent exercise on global cognition (SMD = 0.12, 95 % CI: -0.08 to 0.33, p = 0.200). The subgroup analysis indicated that concurrent exercise cannot enhance global cognition compared to active controls (SMD = -0.03, 95 % CI: -0.23 to 0.18, p = 0.80), but it does show significant improvement compared to passive controls (SMD = 0.35, 95 % CI: 0.14 to 0.56, p < 0.001). Moderate heterogeneity was observed (I2 = 49.9 %), and sensitivity analyses confirmed the stability of the results. No significant publication bias was identified. While concurrent exercise was effective in improving global cognition in healthy older adults, the improvements were not superior to active control conditions. Future research should investigate optimal training combinations and sequences to maximize cognitive benefits.

Physical activity, cathepsin B, and cognitive health

Regular physical activity (PA) is beneficial for cognitive health, and cathepsin B (CTSB) - a protease released by skeletal muscle during PA - acts as a potential molecular mediator of this association. PA-induced metabolic and mechanical stress appears to increase plasma/serum CTSB levels. CTSB facilitates neurogenesis and synaptic plasticity in brain regions (e.g., hippocampus and prefrontal cortex) that support performance in specific cognitive domains including memory, learning, and executive function. However, the evidence regarding the role of PA-induced changes in CTSB as a mediator of PA-induced cognitive health in humans is mixed. To guide future research, this article identifies key factors that may explain the observed heterogeneity in the findings from human studies and proposes a PA-CTSB-cognition model.

Effects of human concurrent aerobic and resistance training on cognitive health: A systematic review with meta-analysis

Background

The rising prevalence of cognitive decline and neurodegenerative diseases, projected to affect 150 million individuals by 2050, highlights the urgent need to enhance neurocognitive health. While both aerobic and resistance training are recognized as effective strategies, their combined effects on cognition remain underexplored.

Objective

This study aimed to determine if concurrent aerobic and resistance training (CT) is effective in enhancing cognitive function.

Methods

Seven English and three Chinese databases were searched from inception to August 2024. Randomised controlled trials (RCTs) examining the effects of CT on global cognition across diverse populations were included. A meta-analysis was performed using a random-effects model in R and Stata, supplemented by subgroup and meta-regression analyses to explore variability.

Results

The meta-analysis included 35 RCTs with 5,734 participants, revealing a positive effect of CT on global cognition (g = 0.32, 95% CI: 0.17-0.46, p < 0.001). Notably, older adults (≥65 years) exhibited greater cognitive benefits (g = 0.33; 95% CI: 0.14-0.51, p < 0.05) compared to younger populations. Significant effects were also observed in clinical populations (g = 0.28; 95% CI: 0.11-0.46, p < 0.001). Exercise frequency and duration positively influenced outcomes, with medium-length interventions (13-26 weeks) demonstrating significant effects (g = 0.21; 95% CI: 0.05-0.37, p = 0.011).

Conclusion

The findings indicate that CT significantly enhances cognitive health, particularly in older adults and clinical populations. Prioritizing strength training, implementing short- to medium-term interventions (4-26 weeks), and maintaining session durations of 30-60 minutes are crucial for optimizing cognitive benefits.

Effect of the ActivaMotricidad Program on Improvements in Executive Functions and Interpersonal Relationships in Early Childhood Education

Background: The objective of this study was to analyze the impacts of a comprehensive physical exercise program with cognitive involvement during the school day on the executive functions and interpersonal skills of 5- and 6-year-old children. Methods: A total of 68 children participated in a 3-week pre-post intervention. Results: The results showed significant improvements in executive functions and interpersonal skills under the experimental conditions compared to the control group. These positive effects were observed to persist after a three-week follow-up. Conclusions: Therefore, the ActivaMotricidad program, which focuses on developing fundamental motor skills through cognitive, cooperative, and coordinative challenges, can serve as a useful and low-cost tool to achieve the objectives of comprehensive development and sustainability for children in early childhood education.

The Impact of Different Telerehabilitation Methods on Peripheral Muscle Strength and Aerobic Capacity in COPD Patients: A Randomized Controlled Trial

Lung diseases have profound effects on the aging population. We aimed to hypothesize and investigate the effect of remote pulmonary telerehabilitation and motor imagery (MI) and action observation (AO) methods on the clinical status of elderly chronic obstructive pulmonary disease (COPD) patients. Twenty-six patients were randomly assigned to pulmonary telerehabilitation (PtR) or cognitive telerehabilitation (CtR) groups. The programs were carried out 3 days a week for 8 weeks. The 6-min walk test (6MWT), modified Medical Research Council dyspnea score, blood lactate level (BLL), measurement of peripheral muscle strength (PMS), and electromyography activation levels of accessory respiratory muscles were the main outcomes. There was a statistically significant improvement (p < 0.05) in both groups in the 6MWT distance and in secondary results, except for BLL. Generally, in the mean muscle activity obtained from the electromyography measurement after the program, there were statistically significant increases in the PtR group and decreases in the CtR group (p < 0.05). There was a statistically significant increase in PMS in both groups. An active muscle-strengthening program has the same benefits as applying the muscle-strengthening program to the patient as MI and AO. CtR can be a powerful alternative rehabilitation method in respiratory patients who cannot tolerate active exercise programs.

Volleyball training improves working memory in children aged 7 to 12 years old: an fNIRS study

This study aimed to investigate the effect of a 12-wk extracurricular volleyball training on working memory from both behavioral and cerebral aspects. A total of 80 children were randomized assigned to (i) the experimental group, who engaged in extracurricular volleyball training for 60 min, thrice a week for 12 wk, and (ii) the control group, who maintained their regular daily routine. Working memory was evaluated in both groups using the N-back task before and after the intervention. Furthermore, functional near-infrared spectroscopy was employed to monitor the level of oxygenated hemoglobin in the prefrontal cortex. The experimental group performed better in the behavioral task than the control group, as evidenced by a shorter response time and a higher correct rate. The functional near-infrared spectroscopy results suggested that the activation of the left dorsolateral prefrontal cortex was significantly higher in the experimental group than in the control group. In addition, correlation analyses showed that the enhancement of left dorsolateral prefrontal cortex activation was significantly correlated with decreasing response time and improving response accuracy in the N-back task. These findings suggest that the left dorsolateral prefrontal cortex is likely the neural substrate for improved working memory performance elicited by 12-wk open skill exercise.

Step count and multiple health outcomes: An umbrella review

OBJECTIVE

This study aimed to quantify the association between step count and multiple health outcomes in a healthy population.

METHODS

PubMed, Embase, Web of Science, and The Cochrane Library were systematically searched for systematic reviews and meta-analyses from inception to April 1, 2022. Literature screening, data extraction, and data analysis were performed in this umbrella review. The intervention factor was daily step counts measured based on devices. Multiple health outcomes included metabolic diseases, cardiovascular diseases, all-cause mortality, and other outcomes in the healthy population.

RESULTS

Twenty studies with 94 outcomes were identified in this umbrella review. The increase in daily step count contributed to a range of human health outcomes. Furthermore, the special population, different age groups, countries, and cohorts should be carefully considered. Negative correlation between step counts and the following outcomes: metabolic outcomes, cardiovascular diseases, all-cause mortality, postural balance, cognitive function, and mental health. However, there was no association between participation in the outdoor walking group and the improvement of systolic blood pressure and diastolic blood pressure. Analysis of the dose-response association between increasing daily step count and the risk of cardiovascular disease events and all-cause mortality showed a substantially linear relationship.

CONCLUSION

A wide range of health outcomes can benefit from the right number of steps.

Effects of rope skipping exercise on working memory and cardiorespiratory fitness in children with attention deficit hyperactivity disorder

Introduction

Children with Attention Deficit Hyperactivity Disorder (ADHD) exhibit deficits in working memory (WM) and cardiorespiratory fitness (CRF), both of which are closely associated with the core symptoms of ADHD. This study aimed to investigate the effects of rope skipping exercise (RSE) on the WM and CRF of children with ADHD, to provide a theoretical foundation for the optimization of exercise intervention programs tailored to children with ADHD.

Methods

This study recruited 55 children (age range 6-12 years) and randomly assigned them into three groups: the ADHD with RSE (AWRSE, n=22, mean age: 10.18 ± 1.10 years), the ADHD with sports game (SG) (AWSG, n=16, mean age: 9.38 ± 0.96 years), and the typically developing (TD) control group (CG, n=17, mean age: 8.94 ± 0.56 years). The AWRSE underwent a RSE intervention, while the other two groups participated in SG. The exercise intervention lasted for 8 weeks, with sessions held twice a week for 60 minutes each, at a moderate-to-vigorous-intensity (64-95% HRmax). All children in each group underwent pre-test and post-test, including height, weight, BMI, n-back, and 20mSRT. One-way analysis of variance (Ony-way ANOVA) and paired sample t-test were used to analyze inter- and intra-group differences respectively.

Results

Before the intervention, children with ADHD exhibited a significantly lower VO2max compared to the TD children (p<0.05), and there was no significant difference in the other indicators between the groups (p>0.05). After the intervention, no significant inter-group differences were found across all indices for the three groups of children (p > 0.05). The AWRSE had significant improvements in the accuracy of 1-back task, Pacer (laps), and VO2max (p<0.05), with the level of CRF approaching that of TD children. A significant decrease in response time for the 1-back task was observed in the CG.

Conclusion

An 8-week RSE intervention is an effective therapeutic approach for children with ADHD, significantly enhancing their WM and CRF.

Grip strength, working memory, and emotion perception in middle-aged males

This study examined the association between grip strength and emotional working memory in middle-aged adults. Seventy-six males aged 40-60years (mean=48.5years, SD=5.4) participated in this cross-sectional study. They completed a muscular fitness assessment using a maximum grip strength test and emotional n-back tasks under two emotion conditions (fearful and neutral facial pictures) and two working memory loads (1-back and 2-back tasks). Hierarchical regression analyses indicated that greater muscular fitness was associated with superior working memory performance in the fearful condition in both the 1-back and 2-back tasks, after controlling for confounders. Greater muscular fitness was also associated with superior working memory performance in the neutral condition when the working memory load was high (2-back task) but not low (1-back task). These findings suggest a positive association between muscular fitness and emotional working memory and highlight the importance of maintaining muscular fitness for physical and cognitive-emotional well-being in middle-aged adults.

Lifestyle Factors Counteract the Neurodevelopmental Impact of Genetic Risk for Accelerated Brain Aging in Adolescence

BACKGROUND

The transition from childhood to adolescence is characterized by enhanced neural plasticity and a consequent susceptibility to both beneficial and adverse aspects of one's milieu.

METHODS

To understand the implications of the interplay between protective and risk-enhancing factors, we analyzed longitudinal data from the Adolescent Brain Cognitive Development (ABCD) Study (n = 834; 394 female). We probed the maturational correlates of positive lifestyle variables (friendships, parental warmth, school engagement, physical exercise, healthy nutrition) and genetic vulnerability to neuropsychiatric disorders (major depressive disorder, Alzheimer's disease, anxiety disorders, bipolar disorder, schizophrenia) and sought to further elucidate their implications for psychological well-being.

RESULTS

Genetic risk factors and lifestyle buffers showed divergent relationships with later attentional and interpersonal problems. These effects were mediated by distinguishable functional neurodevelopmental deviations spanning the limbic, default mode, visual, and control systems. More specifically, greater genetic vulnerability was associated with alterations in the normative maturation of areas rich in dopamine (D2), glutamate, and serotonin receptors and of areas with stronger expression of astrocytic and microglial genes, a molecular signature implicated in the brain disorders discussed here. Greater availability of lifestyle buffers predicted deviations in the normative functional development of higher density GABAergic (gamma-aminobutyric acidergic) receptor regions. The two profiles of neurodevelopmental alterations showed complementary roles in protection against psychopathology, which varied with environmental stress levels.

CONCLUSIONS

Our results underscore the importance of educational involvement and healthy nutrition in attenuating the neurodevelopmental sequelae of genetic risk factors. They also underscore the importance of characterizing early-life biomarkers associated with adult-onset pathologies.

Physical activity and verbal memory performance: Mediating effects of resting-state brain activity

Verbal short-term and long-term memory are crucial neuropsychological functions involved in core cognitive abilities. They constitute vital components of subjective well-being and academic achievement. To date, there is limited research on the association between regular physical activity and memory abilities during young adulthood. The Individual Alpha Peak Frequency (IAPF) contributes to various cognitive abilities and also appears to be sensitive to physical activity. Consequently, the IAPF has the potential to underlie the association between physical activity and verbal memory. We examined the direct relation of physical activity and verbal memory, and the potential indirect relation via IAPF in young adults. Regular physical activity was assessed via accelerometry on seven consecutive days in 115 participants (N=115, 48% female) aged 18-35 years (M=24.1, SD=3.8). In addition, verbal memory performance was assessed using an immediate and delayed free-recall task. Brain activity during rest was recorded with EEG, and IAPF was extracted for mediation analyses. Path analysis revealed pronounced sex differences in the association between physical activity, IAPF, and verbal memory performance. Exclusively in female participants, higher vigorous physical activity levels were associated with better recall performance. In contrast, no association of physical activity and memory was found in male participants. However, being more physically active was related to a higher IAPF exclusively in male participants. Physical activity shows differential associations between IAPF and verbal memory in male and female participants. However, the lack of a mediating role of IAPF suggests that this neurophysiological marker cannot explain these specific associations in young adults.

Effect of physical exercise in real-world settings on executive function of atypical children: A systematic review and meta-analysis

BACKGROUND

Impaired executive function is a core symptom of cognitive impairment in atypical children. The purpose of this systematic review and meta-analysis is to explore the effectiveness of interventions for exercise in real-life settings on executive function in atypical children.

METHODS

This study searched the CNKI, Wan-Fang, VIP, WOS, PubMed, Scopus and EBSCO databases. Two researchers independently selected articles, extracted data and assessed the risk of bias for the included studies. Exercise activities were categorized into open and closed skills based on the unpredictability of the environmental context and into sequential and continuous skills based on the complexity of the movement structure. Based on these two classifications, motor skills were categorized into open-sequential (e.g. basketball), open-continuous (e.g. obstacle running), closed-sequential (e.g. martial arts) and closed-continuous (e.g. swimming) skills. The SPSS 25.0 and Stata 16.0 software were used for statistical analysis.

RESULTS

A total of 19 articles (23 studies) were included in the systematic review and meta-analysis. The participants were 990 atypical children with neurodevelopmental disorders. Physical exercise in real-world settings had significant intervention effects on inhibitory control (SMD = -0.592, P = 0.033), working memory (SMD = -0.473, P = 0.034) and cognitive flexibility (SMD = -0.793, P = 0.014) in atypical children. Quantitative intervention characteristics and motor skill types moderated the effect of exercise on promoting executive function in atypical children. Overall, exercise for 30-50 min, three to seven times a week for less than 10 weeks is effective in improving executive function in atypical children. Open skills and sequential skills have a positive intervention effect on more dimensions of executive function in atypical children.

CONCLUSIONS

Physical exercise in real-world settings has a positive intervention effect on executive function in atypical children. We should design interventions based on the personality traits of the subject and the type of exercise they are interested in to better promote improved executive function in atypical children.

The effects of an exercise intervention on neuroelectric activity and executive function in children with overweight/obesity: The ActiveBrains randomized controlled trial

OBJECTIVE

To investigate whether a 20-week aerobic and resistance exercise program induces changes in brain current density underlying working memory and inhibitory control in children with overweight/obesity.

METHODS

A total of 67 children (10.00 ± 1.10 years) were randomized into an exercise or control group. Electroencephalography (EEG)-based current density (μA/mm2 ) was estimated using standardized low-resolution brain electromagnetic tomography (sLORETA) during a working memory task (Delayed non-matched-to-sample task, DNMS) and inhibitory control task (Modified flanker task, MFT). In DNMS, participants had to memorize four stimuli (Pokemons) and then select between two of them, one of which had not been previously shown. In MFT, participants had to indicate whether the centered cow (i.e., target) of five faced the right or left.

RESULTS

The exercise group had significantly greater increases in brain activation in comparison with the control group during the encoding phase of DNMS, particularly during retention of second stimuli in temporal and frontal areas (peak t = from 3.4 to 3.8, cluster size [k] = from 11 to 39), during the retention of the third stimuli in frontal areas (peak t = from 3.7 to 3.9, k = from 15 to 26), and during the retention of the fourth stimuli in temporal and occipital areas (peak t = from 2.7 to 4.3, k = from 13 to 101). In MFT, the exercise group presented a lower current density change in the middle frontal gyrus (peak t = -4.1, k = 5). No significant change was observed between groups for behavioral performance (p ≥ 0.05).

CONCLUSION

A 20-week exercise program modulates brain activity which might provide a positive influence on working memory and inhibitory control in children with overweight/obesity.

Effects of open and closed skill exercise interventions on executive function in typical children: a meta-analysis

BACKGROUND

The effects of open and closed skill exercise interventions for executive function in children and adolescents have received widespread attention. Open skill refers to the skill of performing motor tasks in an unpredictable environment; closed skill refers to the skill of performing motor tasks in a stable environment. However, the results of related studies are currently controversial and Meta-analysis is urgently needed.

METHODS

After computer searches of CNKI, Wan-Fang, VIP, WOS, PubMed, and EBSCO databases, two researchers independently screened articles, extracted information, and evaluated the quality of the articles. This study was statistical analyzed using Stata 16.0 software.

RESULTS

A total of 31 articles were included, including 2988 typical children. Open, closed, continuous and sequential skills all improved executive function in typical children to varying degrees, but open and sequential skills were more effective in improving executive function, particularly in the former in the working memory (SMD=-0.833, P < 0.001) and in the latter in the inhibitory control (SMD=-0.834, P < 0.001) and cognitive flexibility (SMD=-0.903, P < 0.001). Long-term, moderate- intensity interventions were better than acute, vigorous-intensity interventions for executive function, with long-term interventions reflected in working memory (SMD=-0.579, P < 0.001) and moderate-intensity interventions reflected in all three dimensions of executive function (P < 0.01). Intervention periods, intervention intensity and continuous and sequential skills classified by action structure play a significant moderating role. Better results for long-term, sequential structural action interventions based on open skills (P < 0.001); better results for acute, moderate intensity, sequential structural action interventions based on closed (P < 0.05). Whereas intervention intensity had a non-significant moderating effect in the open skills intervention, both moderate and vigorous intensity had a significant effect on executive function (P < 0.001).

CONCLUSION

Open and closed skills have different levels of facilitation effects on executive function in typical children, but open skills are more effective. The facilitation effects of open and closed skills were moderated by the qualitative characteristics and action structure of the intervention.

Effects of Physical Exercise on Executive Functions among College Students in China: Exploring the Influence of Exercise Intensity and Duration

BACKGROUND

This study investigates the effects of exercise intensity and duration on executive functions among college students in China.

METHOD

Participants in this study were Chinese college students divided into four groups based on exercise duration and intensity. Each group engaged in physical exercise twice a week for six weeks. Group 1 performed low-intensity exercises for 10 min per session; Group 2 performed low-intensity exercises for 20 min per session; Group 3 performed high-intensity exercises for 10 min per session; and Group 4 performed high-intensity exercise for 20 min per session. Executive functions were assessed in all subjects before the experiment (time 1), after one exercise session (time 2), at the end of the exercise program (time 3), and six weeks after the exercise program (time 4). A mixed ANOVA with a 2 (exercise intensity: low/high) × 2 (duration: short/long) × 4 (time of measurement: time 1/time 2/time 3/time 4) design was employed, with exercise intensity and exercise duration as independent variables and executive functions as the dependent variable.

RESULTS

Mixed ANOVA showed that the results revealed a significant main effect of measurement time on working memory accuracy (p < 0.001) and reaction time (p < 0.001); inhibition control accuracy (p < 0.001) and reaction time (p < 0.001); cognitive flexibility accuracy (p < 0.001) and reaction time (p < 0.001). A single session of high-intensity exercise significantly improved executive functions in college students. Both low-intensity and high-intensity exercise were effective in enhancing executive functions, with high-intensity exercise demonstrating better maintenance of the effect.

CONCLUSION

Both exercise intensity and exercise duration were found to enhance executive functions in college students, with exercise intensity showing greater effectiveness than exercise duration.

Association of physical activity and fitness with executive function among preschoolers

It is well-documented in the literature that high levels of regular physical activity (PA), low levels of sedentary behavior (SB), and high levels of cardiorespiratory fitness (CRF) are associated with superior cognitive functioning, especially with regard to older populations. However, concerning other age groups (e.g., preschoolers) the available evidence documenting such a positive relationship is relatively scarce. Thus, this study aimed to investigate the association of time spent in different PA intensity zones and CRF with executive functions (EFs) in preschool-age children. To this end, preschoolers (n = 127) aged 3 to 6 years were recruited from 9 kindergarten classes in 2 districts of Shenzhen, China. The amount and the intensity of PA were assessed via accelerometry, and the CRF level was quantified by the 20-meter shuttle run test. EFs including inhibitory control and working memory were assessed using the one-on-one iPad-based Early Year Toolbox. Results suggested that children who had a higher CRF level ("impulse control" scores: β = 0.34, p < .001; "Go" accuracy: β = 0.31, p < .001; "No-Go" accuracy: β =0.28, < .001) and spentmore time in moderate-to-vigorous physical activity (MVPA) ("impulse control" scores: β = 0.50, p < .001; No-Go" accuracy: β = 0.52, p < .001) had higher scores on inhibitory control tasks, and those who had a higher CRF level had higher scores on a working memory task (β = 0.24, p < .05). The findings are discussed in light of the positive roles of MVPA and CRF for promoting EFs, but also consider the disproportionate association of PA and CRF with working memory relative to inhibition.

Differential features of early childhood motor skill development and working memory processing: evidence from fNIRS

Objective

The study investigated the differential characteristics associated with motor skill development and working memory processing during early childhood, thereby providing insights for understanding motor learning and cognitive development in young children.

Methods

In total, 101 preschool children (age: 4-6 years) were recruited for this study. The motor skill development level and the working memory capacity of the children were assessed using the MOBAK Motor Development Assessment Scale and a block task paradigm, respectively. Functional near-infrared spectroscopy brain imaging technology was used to monitor hemodynamic signals in the prefrontal cortex (PFC) of the children while they completed different memory tasks. MATLAB software and the Homer2 plugin were used to calculate the oxygenated hemoglobin (Oxy-Hb) concentration in relevant brain regions during the tasks.

Results

(1) The low motor skill group exhibited significantly lower accuracy during the three-memory load condition than during the two-memory load condition. Under both two-memory and three-memory load conditions, the high motor skill group exhibited significantly higher accuracy than the low motor skill group. (2) Significant differences in the Oxy-Hb concentration were observed in the left dorsolateral PFC (L-DLPFC), and right and left triangular part of the Broca's area (R-PTBA and L-PTBA, respectively) between the two memory difficulty levels for the high motor skill group. The Oxy-Hb concentration was significantly higher during the three-memory load condition than during the two-memory load condition. Under the two-memory load condition, the high motor skill group exhibited significantly higher Oxy-Hb concentration in the L-DLPFC and L-PTBA regions than in the low motor skill group. Under the three-memory load condition, the high motor skill group exhibited significantly higher Oxy-Hb concentration in the L-DLPFC, R-PTBA, and L-PTBA regions than the low motor skill group.

Conclusion

A close association was observed between the motor skill levels and working memory in young children, with higher motor skill levels being associated with more pronounced brain activation patterns during working memory tasks.

Head-Toes-Knees-Shoulders task and EF in two samples of adolescents in Brazil and United States

Executive function (EF) is a foundational cognitive construct, which is linked to better cognitive and physical health throughout development. The present study examines the construct validity of an EF task, the Head-Toes-Knees-Shoulders task (HTKS) that was initially developed for young children, in a sample of adolescents. We investigate the initial validity and range in scores between 54 adolescents from Brazil (mean age 12.58) and 56 US adolescents (mean age 12.48) from different socioeconomic contexts. Results indicated that the HTKS showed sufficient variability in both samples, especially for a measure of HTKS efficiency (completion time divided by the total score). The US sample performed better on all cognitive measures. For the Brazilian sample, regression models controlling for age and sex showed a significant relationship between the digit span working memory task, the HTKS total score, and the HTKS efficiency score. The Heart and Flowers cognitive flexibility measure was also included as an independent variable only for the Brazil sample, showing a significant relationship with both HTKS scores. For the US sample, results showed that only the HTKS efficiency score was significantly related to the digit span working memory task. This study highlights the importance of cognitive efficiency measures to achieve greater validity, as they can assess a broader range of performance with different populations. The HTKS showed good ecological validity with two adolescent samples, as it differentiated between populations with high and low socioeconomic status from different cultural contexts.

Look into my eyes: What can eye-based measures tell us about the relationship between physical activity and cognitive performance?

BACKGROUND

There is a growing interest to understand the neurobiological mechanisms that drive the positive associations of physical activity and fitness with measures of cognitive performance. To better understand those mechanisms, several studies have employed eye-based measures (e.g., eye movement measures such as saccades, pupillary measures such as pupil dilation, and vascular measures such as retinal vessel diameter) deemed to be proxies for specific neurobiological mechanisms. However, there is currently no systematic review providing a comprehensive overview of these studies in the field of exercise-cognition science. Thus, this review aimed to address that gap in the literature.

METHODS

To identify eligible studies, we searched 5 electronic databases on October 23, 2022. Two researchers independently extracted data and assessed the risk of bias using a modified version of the Tool for the assEssment of Study qualiTy and reporting in EXercise (TESTEX scale, for interventional studies) and the critical appraisal tool from the Joanna Briggs Institute (for cross-sectional studies).

RESULTS

Our systematic review (n = 35 studies) offers the following main findings: (a) there is insufficient evidence available to draw solid conclusions concerning gaze-fixation-based measures; (b) the evidence that pupillometric measures, which are a proxy for the noradrenergic system, can explain the positive effect of acute exercise and cardiorespiratory fitness on cognitive performance is mixed; (c) physical training- or fitness-related changes of the cerebrovascular system (operationalized via changes in retinal vasculature) are, in general, positively associated with cognitive performance improvements; (d) acute and chronic physical exercises show a positive effect based on an oculomotor-based measure of executive function (operationalized via antisaccade tasks); and (e) the positive association between cardiorespiratory fitness and cognitive performance is partly mediated by the dopaminergic system (operationalized via spontaneous eye-blink rate).

CONCLUSION

This systematic review offers confirmation that eye-based measures can provide valuable insight into the neurobiological mechanisms that may drive positive associations between physical activity and fitness and measures of cognitive performance. However, due to the limited number of studies utilizing specific methods for obtaining eye-based measures (e.g., pupillometry, retinal vessel analysis, spontaneous eye blink rate) or investigating a possible dose-response relationship, further research is necessary before more nuanced conclusions can be drawn. Given that eye-based measures are economical and non-invasive, we hope this review will foster the future application of eye-based measures in the field of exercise-cognition science.

Meta-analysis of the effects of physical activity on executive function in children and adolescents with attention deficit hyperactivity disorder

BACKGROUND

Executive function is a core deficit in children with attention deficit hyperactivity disorder (ADHD). This study systematically reviewed the evidence for the effects of physical activity (PA) interventions on executive function in children and adolescents with ADHD and explored the moderating effects of key variables of PA on executive function.

METHODS

Relevant literature in four electronic databases, Pubmed, Web of Science, Cochrane Library, and Embase, were systematically searched. Revman 5.4 was used for data analysis, and combined effect sizes, heterogeneity tests, subgroup analyses, and sensitivity analyses were calculated. Egger's test in Stata 15.0 was used for publication bias testing.

RESULTS

A total of 24 articles with 914 participants were included. Meta-analysis showed that PA interventions improved inhibitory control (SMD = -0.50, 95%CI [-0.71, -0.29], P < 0.00001), working memory (SMD = -0.50, 95%CI [-0.83, -0.16], P = 0.004) and cognitive flexibility in children and adolescents with ADHD (SMD = -0.45, 95%CI [-0.81, -0.09], P = 0.01). Subgroup analysis revealed a moderating effect of intervention intensity, motor skill type, sessions of PA, and weekly exercise volume on executive function.

CONCLUSION

PA interventions had positive effects on improvements in core executive functions in children and adolescents with ADHD and were influenced by intervention intensity, type of motor skill, sessions of PA, and amount of exercise. This has practical implications for the formulation of PA interventions programs.

The efficacy of physical exercise interventions on mental health, cognitive function, and ADHD symptoms in children and adolescents with ADHD: an umbrella review

Background

A considerable number of published reviews have addressed the effects of physical exercise on mental health, cognitive function, or attention-deficit hyperactivity (ADHD) symptoms as outcomes in children and adolescents with ADHD. Their findings have often conflicted, therefore, there is an urgent need to synthesise a hierarchy of the evidence and examine the credibility of previous meta-analyses. To establish the robustness of these findings, we conducted an additional meta-analysis on a number of individual studies that were not covered in previous reviews but were suitable for inclusion in our own study.

Methods

Three reviewers independently searched Web of Science, Psych INFO, Embase, Cochrane Library, PubMed, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) for meta-analyses published between database inceptions to December 1, 2022. The individual studies were also screened from 1 January 2015 to 1 December 2022. We included meta-analyses and eligible individual studies that addressed the effects of exercise on at least one outcome of mental health, cognitive function, or ADHD symptoms in children and adolescents with ADHD. We excluded systematic reviews and articles that lacked sufficient data for a meaningful second analysis. The effect estimates (Hedges' g), 95% confidence interval (95% CI), 95% prediction interval (95% PI), small study effects, and excess significance bias were calculated. Finally, we categorised the meta-analyses based on the credibility of the evidence criteria and their quality using a Measurement Tool to Assess Systematic Reviews 2 checklist. This umbrella review was registered with PROSPERO, CRD42022361331.

Findings

Of 181 listed review articles and 60 individual papers, 10 reviews and 12 individual articles were included in the meta-analyses. This yielded 37 meta-analyses based on 106 study estimates. Evidence was highly suggestive for the effectiveness of exercise (class II) for improving inattention (G = 0.92, 95% CI: 0.44-1.39, 95%), inhibitory control (G = 0.82, 95% CI: 0.52-1.13), and cognitive flexibility (G = 0.52, 95% CI: 0.32-0.72). However, evidence for the effectiveness of exercise on emotional, social, and working memory outcomes was weak, and these results were not significant for hyperactivity and behavioural functioning.

Interpretation

Improvement of cognitive flexibility, inhibitory control, and inattention in children and adolescents with ADHD was highly suggested by exercise interventions. However, results were weak for other outcomes (emotional functioning, social functioning, and working memory). Further high-quality randomised controlled trials are, therefore, warranted to determine the effectiveness of exercise on weak outcomes.

Adolescent neurodevelopment and psychopathology: The interplay between adversity exposure and genetic risk for accelerated brain ageing

In adulthood, stress exposure and genetic risk heighten psychological vulnerability by accelerating neurobiological senescence. To investigate whether molecular and brain network maturation processes play a similar role in adolescence, we analysed genetic, as well as longitudinal task neuroimaging (inhibitory control, incentive processing) and early life adversity (i.e., material deprivation, violence) data from the Adolescent Brain and Cognitive Development study (N = 980, age range: 9-13 years). Genetic risk was estimated separately for Major Depressive Disorder (MDD) and Alzheimer's Disease (AD), two pathologies linked to stress exposure and allegedly sharing a causal connection (MDD-to-AD). Adversity and genetic risk for MDD/AD jointly predicted functional network segregation patterns suggestive of accelerated (GABA-linked) visual/attentional, but delayed (dopamine [D2]/glutamate [GLU5R]-linked) somatomotor/association system development. A positive relationship between brain maturation and psychopathology emerged only among the less vulnerable adolescents, thereby implying that normatively maladaptive neurodevelopmental alterations could foster adjustment among the more exposed and genetically more stress susceptible youths. Transcriptomic analyses suggested that sensitivity to stress may underpin the joint neurodevelopmental effect of adversity and genetic risk for MDD/AD, in line with the proposed role of negative emotionality as a precursor to AD, likely to account for the alleged causal impact of MDD on dementia onset.

The unique contribution of motor ability to visuospatial working memory in school-age children: Evidence from event-related potentials

This study investigated the unique contribution of motor ability to visuospatial working memory (VSWM) and neuroelectric activity in school-age children. Seventy-six children aged 8.7 ± 1.1 years participated in this cross-sectional study. We assessed aerobic fitness using the 20-m endurance shuttle run test, muscular fitness (endurance, power) using a standard test battery, and motor ability (manual dexterity, ball skills, and static and dynamic balance) using the Movement Assessment Battery for Children. A modified delayed match-to-sample test was used to assess VSWM and the P3 component of event-related potentials. Hierarchical regression analyses indicated that greater aerobic fitness was associated with smaller coefficient of variation of reaction time (p = .008), greater muscular fitness was associated with higher response accuracy (p = .022), greater motor ability was associated with higher response accuracy (p < .001) and increased P3 mean amplitude (p < .001) after controlling for age. Furthermore, the positive associations of motor ability with response accuracy (p = .001) were independent of muscular fitness. The findings from this study provide new insight into the differential associations between health-related fitness domains and VSWM, highlighting the influence of motor ability on brain health and cognitive development during childhood.

Effects of physical activity on visuospatial working memory in healthy individuals: A systematic review and meta-analysis

Introduction

Physical activity interventions improve cognitive performance, especially visuospatial working memory (VSWM). However, evidence on the effects of these interventions in children, adolescents, and older adults remains scant. This meta-analysis aimed to identify the effects of physical activity on VSWM improvement in healthy individuals and the best exercise intervention program to improve VSWM capacity.

Methods

We searched for randomized controlled trials (RCTs) of exercise interventions targeting VSWM in healthy individuals from Web of Science, MEDLINE, BIOSIS Previews, PubMed, China National Knowledge Infrastructure, and Wanfang Data (Chinese) databases, from inception to August 20, 2022.

Results

Among 21 articles (1,595 healthy participants), the heterogeneity test statistic was I2 = 32.3%, p = 0.053. The mean quality scores of the included articles were 6.9 points (reaction time [RT] studies) and 7.5 points (Score studies). Moreover, 28 RCTs were included (10 RT studies and 18 Score studies), and the subgroup analysis found significant effects for elderly participants, children, interventions involving a higher level of cognitive engagement, low and moderate exercise intensity, chronic exercise, exercise duration ≥60 min, and exercise period ≥90 days. Physical activity had a small but significant positive impact on VSWM in healthy individuals. Current evidence confirms the effects of physical activity on VSWM capacity only in children and seniors but not in young adults. Other age groups, including adolescents and middle-aged adults, have not been studied. Prescription of interventions involving high-level cognitive engagement, low and moderate exercise intensity, chronic exercise, exercise for >30 min per session, and exercise for more than 3 months is recommended for children and seniors.

Discussion

Future RCTs would be to fill the gap in studies on adolescents and middle-aged adults, and report detailed exercise intervention programs about different age groups.Systematic Review Registration: PROSPERO (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022354737).

Reinvest to Assess: Advancing Approaches to Motor Competence Measurement Across the Lifespan

Measurement of motor competence is a vital process to advancing knowledge in the field of motor development. As motor competence is being more widely linked to research in other academic domains (e.g., public health, neuroscience, behavioral health), it is imperative that measurement methodology and protocols are reproducible with high degrees of validity and reliability. When addressing the plethora of available assessments, mostly developed for youth populations, there are potential questions and concerns that need to be addressed and/or clarified. One of the most prominent issues is the lack of a lifespan measure of motor competence, which is at odds with the premise of the field of motor development-studying changes in motor behavior across the lifespan. We address six areas of concern in lifespan assessment which include: (1) lack of assessment feasibility for conducting research with large samples, (2) lack of accountability for cultural significance of skills assessed, (3) limited sensitivity and discriminatory capabilities of assessments, (4) developmental and ecological validity limitations, (5) a problematic definition of 'success' in skill performance, and (6) task complexity and adaptability limitations. It is important to critically analyze current assessment methodologies as it will help us to envision the development and application of potential new assessments through a more comprehensive lens. Ultimately, we propose that reinvesting in how we think about assessment will be highly beneficial for integrating motor development from a holistic perspective, impact scientific advancements in other developmental domains, and increase global and lifespan surveillance of motor competence.

Effect of Physical Exercise in Real-World Settings on Executive Function of Typical Children and Adolescents: A Systematic Review

OBJECTIVE

The aim of this paper is to provide a systematic review of research on physical exercise in real-world settings on executive function of typical children and adolescents.

METHODS

The CNKI, WOS, PubMed, ScienceDirect, and SPORTDiscus databases were searched by computer. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included literature. Statistical analysis was performed using frequency and percentage and the χ² test.

RESULTS

A total of 49 articles was included. Acute (moderate intensity lasting 30-50 min) and long-term (interventions of moderate intensity of 30-50 min at least 3 times a week for 17 weeks or more) physical exercises in real-world settings have positive intervention effects on executive function. Furthermore, for acute interventions, closed skills are more efficient for inhibitory control, open skills are more efficient for working memory and cognitive flexibility, and open-continuous and closed-sequential skills are the most efficient; long-term interventions with open skills, sequential skills, and open-sequential skills are more effective.

CONCLUSION

Physical exercise in real-world settings has a good promotion effect on typical children and adolescents, and motor skills with open and/or sequential attributes are more helpful in improving executive function.

Effects of acute exercise on memory: Considerations of exercise intensity, post-exercise recovery period and aerobic endurance

Accumulating research demonstrates that acute exercise can enhance long-term episodic memory. However, it is unclear if there is an intensity-specific effect of acute exercise on long-term episodic memory function and whether this is influenced by the post-exercise recovery period, which was the primary objective of this experiment. Another uncertainty in the literature is whether aerobic endurance influences the interaction between exercise intensity and post-exercise recovery period on long-term episodic memory function, which was a secondary objective of this study. With exercise intensity and post-exercise recovery period occurring as within-subject factors, and fitness as a between-subject factor, 59 participants (M_age = 20 years) completed 12 primary laboratory visits. These visits included a 20-min bout of exercise (Control, Moderate, and Vigorous), followed by a recovery period (1, 5, 10, and 15 min) and then a word-list episodic memory task, involving an encoding phase and two long-term recall assessments (20-min and 24-h delayed recall). The primary finding from this experiment was that moderate and vigorous-intensity exercise improved memory function when compared to a non-exercise control. A secondary finding was that individuals with higher levels of aerobic endurance, compared to their lesser fit counterparts, had greater memory performance after exercise (moderate or vigorous) when compared to after a control condition. Additionally, individuals with higher levels of aerobic endurance, compared to their lesser fit counterparts, generally performed better on the memory task with longer post-exercise recovery periods. Future research should carefully consider these parameters when evaluating the effects of acute exercise on long-term episodic memory.

The Effects of a Cognitively Challenging Physical Activity Intervention on School Children's Executive Functions and Motivational Regulations

This study examined the effects of a physical education intervention consisting of cognitively challenging physical activity games on school children's executive functions and motivational regulations. Ninety-nine fourth- and fifth-grade children participated in this two-group, repeated measures, quasi-experimental study with a cross-over design. Children's executive functions (measured with the design fluency and Stroop and flanker tests) and motivational regulations were measured pre- and post-intervention and one month later. At post-test, the experimental group children outperformed the waiting-list control group children in all design fluency test conditions and accuracy in the Stroop and flanker tests. Both groups improved from pre- to post-intervention their speed (reaction time) in the Stroop and flanker tests. The waiting-list control group children, after receiving the intervention, improved their performance in the executive function tests except for Stroop test accuracy and flanker test speed. The positive effects were reduced significantly one month after the end of the intervention but remained significantly higher compared to pre-intervention. No intervention effects were found for the motivational regulations. These results showed that the intervention had positive effects on children's executive functions and supported the new shift of designing physical activity programs for developing combinedly children's physical and cognitive development.

Effect of acute physical exercise on inhibitory control in young adults: High-intensity indoor cycling session

There is growing evidence that physical exercise (PE) may boost cognitive performance. However, criteria regarding PE intensity, duration, and frequency are still being studied. We hypothesize that high PE intensities have effects on inhibitory control. For this reason, our aim was to study the effect of acute PE on IC in healthy young students of a bachelor's degree in physical education and exercise via a 20-minute indoor cycling session at 80-90% HRmax intensity. We devised an experimental group design (n = 9) relative to a control group (n = 10) with pre-and-post-test IC measures. A Stroop task (two conditions) was administered to undergraduate students (Mage = 23.3, SD = 1.6) of a bachelor's degree program in Physical Education and Sports Sciences from a public university in Colombia. The computed MANOVA did not show an interaction effect between the experimental task of Stroop A-B x measure x group. However, a main effect of reduced response time was obtained after PE in the experimental group. Other main effects were observed in the number of correct and incorrect trials in the Stroop-B condition. The experimental group showed fewer correct answers after PE, and the control group showed fewer errors. It is concluded that high-intensity PE confers favorable effects on inhibitory control.

Behavioral and neurocognitive effects of judo training on working memory capacity in children with ADHD: A randomized controlled trial

BACKGROUND

Children with Attention Deficit Hyperactivity Disorder (ADHD) face deficits in working memory capacity that often persist into adulthood. In healthy peers, exercise targeting motor skill acquisition benefits visuospatial working memory, but its potential to reduce ADHD-related deficits remains unclear. We investigated the effect of a judo training program targeting motor skills on behavioral and neurocognitive indices of working memory capacity in children with ADHD.

METHODS

Children with ADHD aged 8 to 12 years (N = 57) were randomly allocated to a judo training group and a wait-list control group. The training program encompassed 120 min of judo per week over three months. Before and after the intervention period, participants completed a bilateral Change Detection task with low and high memory load conditions and the Movement Assessment Battery for Children-2 (MABC-2). The contralateral delay activity (CDA) elicited by the cognitive task was recorded using electroencephalography.

RESULTS

Compared to the control group, the judo training group showed a higher K-score on the Change Detection task and an increased negativity of the CDA on the high load condition following the intervention, when pretest scores (and confounders) were accounted for. In contrast, no group differences were found for MABC-2 score.

CONCLUSION

In children with ADHD, judo training may complement the pharmacological treatment by increasing the effectiveness of working memory maintenance processes. On a behavioral level, this improvement is accompanied with an increased capacity to store visuospatial information.

What Types of Exercise Are Best for Emotional Intelligence and Logical Thinking?

The aim of our study was to determine whether EI and LT vs. intuitive thinking (CRT score) are related to participation in professional sports, independent exercise, and exercise at a gym/health center compared with no exercise. We selected 20 of the most popular types of exercise in Lithuania among respondents who exercise independently or at a gym/health center, and we ranked these types of exercise according to the participants' emotional intelligence and logical thinking. We studied 4545 women and 1824 men aged 18-74 years with a focus on whether emotional intelligence and logical thinking are related to type of exercise. Participation in any exercise was significantly related to emotional intelligence in men and women. Women in professional sports solved the lowest number of logic tasks. Women who exercise independently or at a gym/health center had better logical thinking than those who do not exercise. Among men, logical thinking was not associated with the type of exercise. We found the tendency for a negative correlation between EI and LT in the 20 most popular types of exercise. Emotional intelligence correlated positively with participation in MVPA. The highest emotional intelligence was in women who participate in dance or Pilates and in men who participate in martial arts, wrestling, boxing, or yoga. Logical thinking was the highest in men who participate in triathlon and in women who perform CrossFit. Men who practice martial arts or track and field and women who participate in cycling were in the top five for emotional intelligence and logical thinking.

Changes in working memory performance and cortical activity during acute aerobic exercise in young adults

This study aimed to examine the concurrent performance of working memory and cortical activity during acute aerobic exercise in young adults. In a crossover study design, 27 young adults (mean age = 22.7 ± 3.4 years, 15 women) participated in two experimental conditions in a randomized order: (1) sitting condition (without exercise) and (2) cycling condition (moderate-intensity exercise). Working memory was measured with a modified version of the n-back task. A functional near-infrared spectroscopy (fNIRS) was used to measure cortex activation. In the cycling condition, response time (RT) for the n-back task was significantly faster (p < 0.05). No differences in accuracy were observed between the sitting and cycling conditions. The fNIRS results showed that the oxygenated hemoglobin (oxy-Hb) concentrations in the bilateral frontopolar area (p < 0.05), dorsolateral prefrontal cortex (p < 0.05), and right premotor and supplementary cortex (p < 0.05) were decreased while cycling. The findings indicated that the concurrent performance of working memory was improved during acute aerobic exercise, whereas cortical activity was decreased in some brain regions.

Exploring Cognitive Processes of Knowledge Acquisition to Upgrade Academic Practices

The development of cognitive functions follows certain pathways through brain maturation. Concepts taught at school can be reinforced by understanding the related cognitive functions that enhance learning. The cultural and social diversities faced by the education system worldwide can be solved by understanding the unifying cognitive processes of learning. This knowledge can be effectively used to devise better curriculum and training for students. Cognition, conation, and emotional regulation are the main components that determine an individual’s efficiency to deal with various situations. How the brain receives input, perceives, and organizes these information lays the foundation for learning. The objectives of the study were (i) to explore age-group specific inputs for knowledge acquisition, (ii) to relate knowledge organization to the cognitive processes, and (iii) to identify factors that strengthen the knowledge ensemble through subject-domain allied training. The review focused on studies related to elementary school age (below 7 years), middle school age (7–12 years), and high school age (12 years and above). Published journal articles related to the objectives were randomly reviewed to establish a possible relationship. The findings of this review can help to advance student learning practices and instructional strategies. The findings are listed below. (i) Acquisition of knowledge during early childhood is based on sensory-motor integration on which attentional, perceptual, memory, language, and socialization systems develop. As brain development progresses toward adolescence, meta-awareness and social-emotional cognition influence the student learning process. (ii) Knowledge representations can be strengthened by domain-specific training inputs. (iii) Associational integration of the developmental, cognitive, and conative processes are indicators of curriculum strength. (iv) The strengthening of cognitive processes by rerouting through complementary neural circuitry, such as music, arts, real-life-based experiments, and physical exercises, is an effective way to improve child-friendly instructions.
