Promoting Executive Functioning in Children with Autism Spectrum Disorder Through Mixed Martial Arts Training

Effects of aquatic exercise intervention on executive function and brain-derived neurotrophic factor of children with autism spectrum disorder

BACKGROUND

Limited knowledge exists regarding the effectiveness of aquatic exercise intervention for improving executive function (EF) in children with autism spectrum disorder (ASD). Additionally, the impact of aquatic exercise on brain-derived neurotrophic factor (BDNF) in children with ASD requires further investigation.

AIMS

This study aimed to explore the effects of a 12-week aquatic exercise intervention on core EF and BDNF levels in children with ASD.

METHODS AND PROCEDURES

Thirty children with ASD were assigned to an experimental or control group. The experimental group underwent a 12-week aquatic exercise intervention, while the control group engaged in supervised free activities. Pre- and post-intervention assessments measured EF and BDNF levels.

OUTCOMES AND RESULTS

The experimental group showed significant improvements (p < 0.05) in inhibition control, cognitive flexibility, and BDNF levels. However, working memory did not significantly improve. The control group exhibited no significant changes in EF or BDNF levels.

CONCLUSIONS AND IMPLICATIONS

Aquatic exercise appears to be a beneficial intervention for cognitive development in children with ASD, as it enhances inhibition control, cognitive flexibility, and BDNF levels in children with ASD. Furthermore, the observed improvements in EF following aquatic exercise intervention in children with ASD may be associated with increased BDNF levels.

Physical Activity and Mental Health in Children and Adolescents With Neurodevelopmental Disorders: A Systematic Review and Meta-Analysis

Importance

Children and adolescents with neurodevelopmental disorders experience mental health issues and are encouraged to be brought together in real-life treatment. However, physical activity, which is a promising method for boosting mental health, has only been examined in children and adolescents with certain types of neurodevelopmental disorders.

Objective

To examine the association of physical activity interventions with mental health (ie, cognitive function, psychological well-being, internalizing, and externalizing problems) in children and adolescents with neurodevelopmental disorders and to identify possible moderators.

Data Sources

Studies were searched from inception to May 2023 through Web of Science, PsycINFO, SPORTDiscus, MEDLINE, CINAHL, and ERIC.

Study Selection

Randomized clinical trials or nonrandomized designs applying physical activity interventions and reporting at least 1 mental health outcome in children and adolescents aged 5 to 17 years with neurodevelopmental disorders were included. Two independent reviewers selected and assessed the studies.

Data Extraction and Synthesis

Random multilevel meta-analysis using Hedges g was performed. Data extraction and risk-of-bias assessment were conducted by multiple reviewers. Heterogeneity, publication bias, sensitivity analysis, and moderator analysis were examined to substantiate the results.

Main Outcomes and Measures

The main outcomes were mental health related to cognitive function, psychological well-being, internalizing, or externalizing problems measured by neurocognitive tasks or subjective questionnaires.

Results

A total of 76 studies involving 3007 participants were included in systematic review, 59 of which were used for meta-analysis. The findings indicated that physical activity interventions were associated with significant benefits for overall mental health (g, 0.67; 95% CI, 0.50-0.85), cognitive function (g, 0.74; 95% CI, 0.53-0.95), psychological well-being (g, 0.56; 95% CI, 0.16-0.96), internalizing (g, 0.72; 95% CI, 0.34-1.10), and externalizing problems (g, 0.58; 95% CI, 0.28-0.89). Moderators were also identified: frequency, total sessions, and total duration for overall mental health; total sessions, and total duration for cognitive function; session duration and frequency for psychological well-being; physical activity type for internalizing problems; and session duration for externalizing problems. Moderator analyses showed that type of neurodevelopmental disorder did not modify the associations between physical activity and overall mental health or its subgroups.

Conclusions and Relevance

The findings in this study suggest that children and adolescents with different types of neurodevelopmental disorders may be grouped together when performing physical activity interventions, which were confirmed to be beneficial to overall mental health and its subgroups in this new diagnostic population, but that physical activity interventions should be tailored when targeting different mental health domains.

One Score to Rule Them All? Comparing the Predictive and Concurrent Validity of 30 Hearts and Flowers Scoring Approaches

The Hearts and Flowers (H&F) task is a computerized executive functioning (EF) assessment that has been used to measure EF from early childhood to adulthood. It provides data on accuracy and reaction time (RT) across three different task blocks (hearts, flowers, and mixed). However, there is a lack of consensus in the field on how to score the task that makes it difficult to interpret findings across studies. The current study, which includes a demographically diverse population of kindergarteners from Boston Public Schools (N = 946), compares the predictive and concurrent validity of 30 ways of scoring H&F, each with a different combination of accuracy, RT, and task block(s). Our exploratory results provide evidence supporting the use of a two-vector average score based on Zelazo et al.'s approach of adding accuracy and RT scores together only after individuals pass a certain accuracy threshold. Findings have implications for scoring future tablet-based developmental assessments.

Effect of COGNI-MACHINE computational thinking training on executive functions in children aged 9 to 11: Protocol of a cluster randomized controlled trial

We designed a controlled trial protocol that seeks to contribute to cognitive science by studying the effect of thought training on children's executive functions. The study design is a cluster randomized controlled trial, with intra-subject and inter-subject evaluation, with two parallel groups: an experimental group and a TAU control group. With three measures, pre-test, post-test, and follow-up after three months. The participants will be children aged 9 to 11. The allocation will be randomized by groups and not individually. The sample will be a minimum of 44 participants. The primary measures will be neuropsychological tests to assess executive functions. Secondary measures will be a computational thinking test, neuropsychological tests to assess metacognition and attention, and an acceptability scale. The experimental group will participate in the COGNI-MACHINE computational thinking training designed by the first author. The training frequency will be twice a week in 60 min sessions for 12 weeks. The TAU control group will receive computer science classes as usual during the same time as the experimental group. The evaluators taking the measurements will be blinded to the assignment. The investigators in charge of the intervention will be blinded to the results of the evaluations.

A Short Report on the Impact of Judo on Behaviors and Social Skills of Children With Autism Spectrum Disorder

INTRODUCTION

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by communication difficulty and social deficits. The current treatment employs the use of psychosocial therapy and medication as well as alternative treatments. This is a pilot study that assessed whether participation in judo improved behavior and social skills in children with ASD.

METHODS

Twenty-four students from the Riverside Youth Judo Club were included in the study, after obtaining consent from their parents to participate. Inclusion criteria included participation in judo classes for more than one month and diagnosis of ASD and/or a developmental disability. Parent(s) of the children signed a consent form, filled out a study questionnaire and completed the Social Skills Improvement System Social-Emotional Learning Edition, Parent Form (SSIS-SEL). Parents also had the opportunity to volunteer their child's baseline SSIS-SEL assessment. SSIS-SEL data was taken for four participants and compared to the baseline.

RESULTS

In the study questionnaire, 62.5% of parents agreed that their children demonstrated improvement across all six categories. The category with the greatest improvement was 'Behavior at home', while the category with the least improvement was 'Eye contact'.

CONCLUSION

While the direct impact of judo on special needs children was difficult to assess due to variability in abilities and developmental milestones, we hope that improving awareness regarding the effectiveness of youth sports would impact the long-term quality of life for children with any developmental or mental disability and may help improve their social and behavioral skills in multiple environments.

The Effects of Physical Activity on Academic Performance in School-Aged Children: A Systematic Review

Schools offer a unique environment to influence children's physical activity (PA) levels positively. This study aims to systematically review the evidence surrounding how PA affects academic performance by analysing how the frequency, intensity, time, and type of PA mediate academic performance outcomes. This review was conducted using the PRISMA framework. Keyword searches were conducted in Science Direct, PubMed, and SPORTDiscus. Children that were obese, typically developing, typical weight, disabled, with a developmental disability, from a low socio-economic background, or an ethnic minority were included. A total of 19 studies were included, with a total of 6788 participants, a mean age of 9.3 years (50.2% boys, and 49.8% girls). Overall, 63.2% were nondisabled, while 36.8% were diagnosed with a disability. Two authors met, reviewed papers with regard to the inclusion criteria, and agreed on outputs to be included. Evidence suggests that associations between PA and academic performance were primarily positive or nonsignificant. PA levels of 90 min plus per week were associated with improved academic performance, as was PA performed at moderate to vigorous intensity. The optimal duration of PA was 30-60 min per session, whilst various sports induced positive academic effects. Importantly, findings support that PA does not have a deleterious effect on academic performance but can enhance it.

Improving motor skills and psychosocial behaviors in children with autism spectrum disorder through an adapted judo program

Introduction

This study aimed to investigate the long-term effects of an adapted judo program on the motor skills and psychosocial abilities of children with Autism Spectrum Disorder (ASD).

Methods

All participants had been diagnosed with ASD and were assessed twice, one time at the start of the intervention and again 6 months later, with the Test of Gross Motor Development (TGMD-3) and the Gilliam Autism Rating Scale-Third Edition (GARS-3). A one-way repeated measures MANOVA was carried out in order to evaluate these assessments, and a mediation analysis was done to determine the relationship between them.

Results

The experimental group significantly improved (p &lt; 0.05) from the pre-test to the post-test for several subtests of the TGMD-3 and the GARS-3.

Conclusion

The study shows that participation in an adapted judo program clearly helps to improve the motor skills and psychosocial behaviors of children with ASD.

Characteristics associated with healthcare independence among autistic adults

Background

Healthcare independence refers to someone's ability to assume responsibility for their own health and complete tasks like taking medication as prescribed or scheduling healthcare appointments. Prior studies have shown that autistic people tend to need more support with healthcare tasks than people with other chronic conditions. We sought to identify modifiable and non-modifiable factors linked with healthcare independence among autistic adults.

Method

We conducted a cross-sectional survey to examine how executive functioning skills, restrictive and repetitive behaviors, gender, education, and age were linked with healthcare independence among this population. Participants included: (a) autistic adults (n=19) who are their own legal guardian, who participated via self-report; and (b) family members of autistic adults with a legal guardian (n=11), who provided proxy-reports.

Results

Findings differed between self- and proxy-reports. Among autistic adults who self-reported, difficulties in executive functioning were strongly linked with less healthcare independence. Among proxy-reports, greater restrictive and repetitive behaviors were strongly linked with less healthcare independence. According to the proxy-reports, having not completed high school, being older during the healthcare transition, and being male were all independently linked with less healthcare independence.

Conclusions

Interventions aimed at supporting executive functioning, providing opportunities to increase independence with healthcare tasks, and reducing the extent to which restrictive and repetitive behaviors interfere with daily activities may be viable options for supporting healthcare independence among autistic adults. Our findings are an important first step for future initiatives to better identify individuals who need additional care coordination, supports, or services to maximize healthcare independence.

Influence of Sports Activities on Prosocial Behavior of Children and Adolescents: A Systematic Literature Review

Prosocial behavior plays a key role in interpersonal relationships during the growth of children and adolescents. Good prosocial behavior is the foundation for the healthy development of children and adolescents. In recent years, the role played by some sports activities in children and adolescents’ prosocial behaviors has attracted much attention. However, the effects of physical activity on prosocial behavior have not been summarized. Objective: We aimed to clarify the role of sports activities in children and adolescents’ prosocial behaviors. Methods: We searched databases for 27 interventional studies on the influence of sports activities on children and adolescents’ prosocial behaviors published in peer-reviewed English journals. Subsequently, inductive, summary, analytical, and evaluation methods were used to systematically analyze and evaluate the literature. Results: Sports activities can improve children and adolescents’ prosocial behaviors. Different sports activities also influence children and adolescents’ prosocial behaviors differently. Moreover, sports activities can improve the prosocial behaviors of children and adolescents with special educational needs. Conclusion: This review demonstrates that sports activities improve the prosocial behavior of children and adolescents. At the same time, we find that children and adolescents with special educational needs should be allowed to participate in more sports activities.

Movie Events Detecting Reveals Inter-Subject Synchrony Difference of Functional Brain Activity in Autism Spectrum Disorder

Recently, movie-watching fMRI has been recognized as a novel method to explore brain working patterns. Previous researchers correlated natural stimuli with brain responses to explore brain functional specialization by “reverse correlation” methods, which were based on within-group analysis. However, what external stimuli drove significantly different brain responses in two groups of different subjects were still unknown. To address this, sliding time windows technique combined with inter-Subject functional correlation (ISFC) was proposed to detect movie events with significant group differences between autism spectrum disorder (ASD) and typical development (TD) subjects. Then, using inter-Subject correlation (ISC) and ISFC analysis, we found that in three movie events involving character emotions, the ASD group showed significantly lower ISC in the middle temporal gyrus, temporal pole, cerebellum, caudate, precuneus, and showed decreased functional connectivity between large scale networks than that in TD. Under the movie event focusing on objects and scenes shot, the dorsal and ventral attentional networks of ASD had a strong synchronous response. Meanwhile, ASD also displayed increased functional connectivity between the frontoparietal network (FPN) and dorsal attention network (DAN), FPN, and sensorimotor network (SMN) than TD. ASD has its own unique synchronous response rather than being “unresponsive” in natural movie-watching. Our findings provide a new method and valuable insight for exploring the inconsistency of the brain “tick collectively” to same natural stimuli. This analytic approach has the potential to explore pathological mechanisms and promote training methods of ASD.

Exercise-Based Interventions Aimed at Improving Balance in Children with Autism Spectrum Disorder: A Meta-Analysis

Children with Autism Spectrum Disorder (ASD) often have deficits in motor skills, especially balance. This article presents a meta-analytic review of 15 intervention studies that aimed to improve balance in children and adolescents with ASD. Across these studies, there were 195 participants with ASD for whom pre-intervention and post-intervention balance scores were available. We measured the standardized mean difference (Hedges' g) between their pre-intervention and post-intervention balance scores and found a large, positive effect from these balance interventions (standardized mean difference-1.82 (95% CI [1.34, 2.29])). Various balance intervention procedures were shown to be very efficacious for children and adolescents with ASD. Clearly, balance is a motor skill that is very susceptible to intervention efforts. We also provided recommendations to researchers regarding what information to include when conducting intervention studies.

Effects of Creative Movement Therapies on Social Communication, Behavioral-Affective, Sensorimotor, Cognitive, and Functional Participation Skills of Individuals With Autism Spectrum Disorder: A Systematic Review

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting multiple developmental domains including social communication, behavioral-affective, sensorimotor, and cognitive systems. There is growing evidence for the use of holistic, whole-body, Creative Movement Therapies (CMT) such as music, dance, yoga, theater, and martial arts in addressing the multisystem impairments in ASD. We conducted a comprehensive quantitative and qualitative review of the evidence to date on the effects of CMT on multiple systems in individuals with ASD. The strongest evidence, both in terms of quantity and quality, exists for music and martial arts-based interventions followed by yoga and theater, with very limited research on dance-based approaches. Our review of 72 studies (N = 1,939 participants) across participants with ASD ranging from 3 to 65 years of age suggests that at present there is consistent evidence from high quality studies for small-to-large sized improvements in social communication skills following music and martial arts therapies and medium-to-large improvements in motor and cognitive skills following yoga and martial arts training, with insufficient evidence to date for gains in affective, sensory, and functional participation domains following CMT. Although promising, our review serves as a call for more rigorous high-quality research to assess the multisystem effects of CMT in ASD. Based on the existing literature, we discuss implications of our findings for autism researchers and also provide evidence-based guidelines for clinicians to incorporate CMT approaches in their plan of care for individuals with ASD.

Effects of Cognitive Training Programs on Executive Function in Children and Adolescents with Autism Spectrum Disorder: A Systematic Review

BACKGROUND

Autism Spectrum Disorder is often associated with deficits in executive functions (EFs), which is contributing significantly to individuals with ASD's difficulties in conducting an independent life, particularly considering social skills. Technologies offer promising opportunities to structure EF intervention programs for children on the autistic spectrum.

METHODS

This study aimed to review the effectiveness of randomized controlled trials or quasi-experimental studies of EF interventions delivered to children and young people (up to 23 years old) with a diagnosis of ASD. A special focus was dedicated to document the effectiveness of computerized and non-computerized cognitive training on (1) EFs and on (2) ASD symptomatology and social skills. Of 2601 studies retrieved, 19 fulfilled the inclusion criteria.

RESULTS

Most of the interventions identified were effective in enhancing EFs and reducing symptoms in children and young people with ASD. Limited evidence is available on their generalization to untrained skills (i.e., social abilities) as well as long-term effects.

CONCLUSIONS

There is growing evidence for overall effectiveness of EF training, particularly when computerized. However, caution should be taken when interpreting these findings owing to methodological limitations, the minimal number of papers retrieved, and a small samples of included studies.

Criss-crossing autism spectrum disorder and adult neurogenesis

Autism spectrum disorder (ASD) comprises a group of multifactorial neurodevelopmental disorders primarily characterized by deficits in social interaction and repetitive behavior. Although the onset is typically in early childhood, ASD poses a lifelong challenge for both patients and caretakers. Adult neurogenesis (AN) is the process by which new functional neurons are created from neural stem cells existing in the post-natal brain. The entire event is based on a sequence of cellular processes, such as proliferation, specification of cell fate, maturation, and ultimately, synaptic integration into the existing neural circuits. Hence, AN is implicated in structural and functional brain plasticity throughout life. Accumulating evidence shows that impaired AN may underlie some of the abnormal behavioral phenotypes seen in ASD. In this review, we approach the interconnections between the molecular pathways related to AN and ASD. We also discuss existing therapeutic approaches targeting such pathways both in preclinical and clinical studies. A deeper understanding of how ASD and AN reciprocally affect one another could reveal important converging pathways leading to the emergence of psychiatric disorders.

The Effects of Exercise Interventions on Executive Functions in Children and Adolescents with Autism Spectrum Disorder: A Systematic Review and Meta-analysis

BACKGROUND

Both chronic and acute exercise interventions have reported positive effects on executive functions (EFs) in general populations. However, data on changes in EFs in children and adolescents with autism spectrum disorder (ASD) in response to exercise interventions are still unclear.

OBJECTIVE

This systematic review and meta-analysis aimed to synthesize available empirical studies concerning the effects of exercise interventions on EFs in children and adolescents with ASD.

METHODS

In accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines, the electronic databases CINAHL Complete (via EBSCOhost), SPORTDiscus with Full Text (via EBSCOhost), MEDLINE (via EBSCOhost), Web of Science, ProQuest, and Education Resources Information Center (ERIC; via EBSCOhost) were searched from inception to January 2021. Two authors independently extracted data and conducted a risk-of-bias analysis using the Physiotherapy Evidence Database scale. Randomized controlled trials/quasi-experimental designs that used acute or chronic exercise interventions and assessed EFs through neurocognitive tasks or questionnaires among children and adolescents with ASD were included. In total, 259 articles were identified, of which 15 full texts were independently assessed for eligibility by two authors. In total, 14 articles underwent systematic review, and seven were selected for meta-analysis.

RESULTS

Overall, chronic exercise interventions had a small to moderate positive effect on overall EFs in children and adolescents with ASD (g = 0.342; 95% confidence interval [CI] 0.084-0.600; p < 0.01). Regarding domain-specific EFs, chronic exercise interventions had a small to moderate positive effect on cognitive flexibility (g = 0.312; 95% CI 0.053-0.570; p < 0.01) and inhibitory control (g = 0.492; 95% CI 0.188-0.796; p < 0.01). However, our review found a non-significant effect size (g = 0.212; 95% CI - 0.088 to 0.512) on working memory.

CONCLUSIONS

Chronic exercise interventions appear to have beneficial effects on overall EFs in children and adolescents with ASD, particularly in relation to cognitive flexibility and inhibitory control.

Behavioural Improvements in Children with Autism Spectrum Disorder after Participation in an Adapted Judo Programme Followed by Deleterious Effects during the COVID-19 Lockdown

The public health lockdown prompted by the novel coronavirus (COVID-19) pandemic, which included school closures that may have potentially serious consequences for people with disabilities or special educational needs, disrupted an ongoing adapted judo training intervention in children with Autism Spectrum Disorder (ASD). The purpose of this study was to compare repetitive behaviours, social interaction, social communication, emotional responses, cognitive style and maladaptive speech scores across four time-points: baseline, after an eight-week control period, after an eight-week judo intervention and after an eight-week lockdown period due to COVID-19. The sample consisted of 11 children diagnosed with ASD according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-V), with an intelligence quotient (IQ) range between 60 and 70. Significant improvements were shown following the judo intervention period compared to the baseline and control periods. However, the same values significantly declined during the COVID-19 lockdown period resulting in values lower than those recorded at baseline, and following the control period and the judo intervention. The decline in psychosocial and behavioural scores are likely due to the stress caused by the sudden halt in activity and the increase in sedentary practices associated with the lockdown.

Martial Arts Routine Training Method Based on Artificial Intelligence and Big Data of Lactate Measurement

As a traditional Chinese sport, competitive martial arts routines have a long history. The competition rules are the unified norms and standards formulated for sports competitions. They are a yardstick for referees to judge the technical level and competitive ability of athletes and an essential basis for coaches during training. In particular, the new rules increase the difficulty of martial arts routines training and score, improve the balance movement of various groups, highlight the action specifications, increase the proportion of the score, and strengthen the scoring measures for the performance level. Subsequently, this puts higher requirements for the exceptional technical level of routine athletes. Therefore, it is vital to formulate scientific martial arts systematic training methods. This paper considers the above problem and current popular artificial intelligence technology and constructs a neural network algorithm to solve it. In addition, since lactic acid is a good monitoring indicator of the training load intensity and effect of martial arts routine exercises, this article also considers extensive lactate measurement data to construct martial arts systematic training methods. Through simulations, our experimental verification and the obtained results demonstrate the effectiveness of the proposed algorithm.

The Effect of Physical Activity Interventions on Executive Function Among People with Neurodevelopmental Disorders: A Meta-Analysis

The current meta-analysis comprehensively examined the effects of physical activity interventions on executive function among people with neurodevelopmental disorders. The meta-analysis included 34 studies with 1058 participants aged 5-33 years. Results indicated an overall significant medium effect of physical activity interventions on improving executive function in people with neurodevelopmental disorders under the random-effect model (Hedges' g = 0.56, p < .001). Significant moderators of the effects of physical activity intervention on executive function included age, intervention length and session time, executive function subdomains, and intervention dose (total minutes in the intervention). This meta-analysis provides support for the effectiveness of physical activity interventions on executive function among people with neurodevelopmental disorders. Future studies and limitations are discussed.

Autism Spectrum Disorder: Investigating Predictive Adaptive Behavior Skill Deficits in Young Children

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder that consists of difficulties with social communication and language, as well as the presence of restricted and repetitive behaviors. These deficits tend to present in early childhood and usually lead to impairments in functioning across various settings. Moreover, these deficits have been shown to negatively impact adaptive behavior and functioning. Thus, early diagnosis and intervention is vital for future success within this population. The purpose of this study was to further examine the subscales that comprise the adaptive behavior section of the Bayley®-III to determine which of the ten subscales are predictive of ASD in young children (i.e., ≤ three years of age). A retrospective file review of 273 children participating in Kentucky's early intervention program, First Steps, was completed. The children ranged in age from 18 to 35 months. A binary logistic regression was used to assess the subscales that comprise the adaptive behavior of the section of the Bayley®-III to determine which of the ten subscales are predictive of ASD in young children (i.e., ≤ three years of age). The results indicated that individual lower raw scores in communication, community use, functional preacademics, home living, health and safety, leisure, self-care, self-direction, and social subscales were predictive of an autism diagnosis.

The Effect of Martial Arts Training on Cognitive and Psychological Functions in At-Risk Youths

The current study assessed whether an extended program of martial arts training was a viable intervention for at-risk youths in improving cognitive and psychological functions. Adolescent boys attending specialized education facilities for at-risk youths took part in regular sport lessons or martial arts practice twice a week for 6 months. Hormonal reactivity was assessed during initial training, and measures of psychological (aggression, self-esteem) and cognitive (inhibition, flexibility, speed of processing, and attention) functions were assessed before and immediately following the intervention. Participants in the martial arts training demonstrated significant improvement in the domains of inhibition and shifting and speed of processing. Additionally, initial hormonal reactivity (oxytocin and cortisol) to the intervention predicted significant post-intervention change on several measures of cognitive and psychological functioning. Specifically, oxytocin reactivity predicted improvement in processing speed, as well as reduction of aggression, whereas cortisol reactivity predicted increases in self-esteem. This pioneering, ecologically valid study demonstrates the initial efficacy of this enjoyable, readily available, group intervention for at-risk boys and suggests potential mechanisms that may mediate the process of change.

Hormonal reactivity during martial arts practice among high-risk youths

Martial arts have become a popular afterschool activity for youths across the globe. Accumulating data suggest that these activities may confer substantial cognitive and psychological benefits, and recent efforts have been made to introduce martial arts training into educational and rehabilitation settings. However, few studies have examined the potential mechanisms that may underlie these benefits. The current study evaluated the reactivity of two hormones, oxytocin (OT) and cortisol (CT), thought to be respectively involved in regulating mammalian social behaviors and responsivity to stress, to a session of intensive martial arts training in samples of at high-risk and low-risk (in regular educational establishments) youths. OT and CT were measured at baseline, during peak training, and following a cool down period. Analyses revealed that high-risk youths had lower OT but similar CT baseline levels, compared to low-risk youths, prior to the martial arts session. A significant group by time interaction indicated that whereas the OT levels among low-risk youths returned to baseline levels following training, OT levels among high-risk youths remained elevated. Finally, unlike low-risk youths for whom CT levels continued to increase throughout the training session, high-risk youths showed no significant CT reactivity. This study suggests that some of the beneficial effects of martial arts may be related to hormonal processes, especially increases in OT levels, and highlights the differing effects that training may have in different populations.

Exercise Intervention in Treatment of Neuropsychological Diseases: A Review

Faced with a constant inundation of information and increasing pressures brought by the continuous development of modern civilization, people are increasingly faced with mental health challenges that are only now being actively researched. Mental illness is caused by brain dysfunction due to internal and external pathogenic factors that destroy the integrity of the human brain and alter its function. Regular participation in physical exercise can stimulate the cerebral cortex and simultaneously increase the supply of oxygen and nutrients, helping to preserve or restore normal functioning of the nervous system. In conjunction with other systems of the body, the nervous system constitutes the neuro-humoral regulation system responsible for maintaining the stable state of the human body. This paper is a systematic review of studies investigating the effects of exercise intervention on several common neuropsychological diseases, including depression, anxiety disorder, autism, and attention-deficit/hyperactivity disorder. Furthermore, we discuss possible physiological mechanisms underlying exercise-induced benefits and study limitations that must be addressed by future research. In many cases, drug therapy is ineffective and brings unwanted side effects. Based on the literature, we conclude that exercise intervention plays a positive role and that certain standards must be established in the field to make physical activity consistently effective.

Effects of Mini-Basketball Training Program on Executive Functions and Core Symptoms among Preschool Children with Autism Spectrum Disorders

This study examined the effects of a 12-week mini-basketball training program (MBTP) on executive functions and core symptoms among preschoolers with autism spectrum disorder (ASD). In this quasi-experimental pilot study, 33 ASD preschoolers who received their conventional rehabilitation program were assigned to either a MBTP group (n = 18) or control group (n = 15). Specifically, the experimental group was required to take an additional 12-week MBTP (five days per week, one session per day, and forty minutes per session), while the control group was instructed to maintain their daily activities. Executive functions and core symptoms (social communication impairment and repetitive behavior) were evaluated by the Childhood Executive Functioning Inventory (CHEXI), the Social Responsiveness Scale-Second Edition (SRS-2), and the Repetitive Behavior Scale-Revised (RBS-R), respectively. After the 12-week intervention period, the MBTP group exhibited significantly better performances in working memory (F = 7.51, p < 0.01, partial η² = 0.195) and regulation (F = 4.23, p < 0.05, partial η² = 0.12) as compared to the control group. Moreover, the MBTP significantly improved core symptoms of ASD preschoolers, including the social communication impairment (F = 6.02, p < 0.05, partial η² = 0.020) and repetitive behavior (F = 5.79, p < 0.05, partial η² = 0.016). Based on our findings, we concluded that the 12-week MBTP may improve executive functions and core symptoms in preschoolers with ASD, and we provide new evidence that regular physical exercise in the form of a MBTP is a promising alternative to treat ASD.
