Judo training program improves brain and muscle function and elevates the peripheral BDNF concentration among the elderly

Judo for older adults: the coaches' knowledge and needs of education

This study aimed to explore the views of judo coaches on their perceived knowledge (PK) and needs for education (NE) for training older practitioners. In total, 470 international (Europe = 48%, Americas = 22%, Africa = 23%, Asia = 5% and Oceania = 2%) judo coaches (IJF: level 1 = 55,3%, level 2 = 33%; judo black belt: 3,4 ± 1,7 dan; F = 15%; university education: 68% >BA) responded an online survey encompassing demographic information and 35 items relevant to training older adults (Aging process; Safety and First Aid; Organization & Environment; Physiology and Fitness; Psychology & Mental Health; Teaching & Training) to be rated on a 7-point Likert scale for PK and NE. Non parametric statistics (p > 0.05) was applied to ascertain differences and relationships between PK and NE, respectively. A bivariate go-zone plot was used to highlight items with the lowest PK and the highest NE mean values. The coaches reported high PK (4.5 ± 0.3 pt) and NE (4.7 ± 0.1 pt) values, with significant higher PK values emerging for high education levels and judo experience. In considering their unique needs and special role, the judo coaches presented valuable insights to develop a sustainable educational curriculum tailored to train older judo practitioners.

Effects of combat sports on cognitive function in older people: a systematic review

INTRODUCTION

This systematic review aimed to analyze the available body of published peer-reviewed studies on the effects of combat sports compared with active/passive control on cognitive function and electrophysiological markers of brain activity in older people.

EVIDENCE ACQUISITION

The studies were searched in Scopus, Web of Science, PubMed, MEDLINE, and PsycINFO databases from deadline to June 2023. The PRISMA, TESTEX, RoB, and GRADE scales assessed the evidence's methodological quality and certainty of evidence. The protocol was registered in PROSPERO (code: CRD42022361695).

EVIDENCE SYNTHESIS

After reviewing 3768 studies, seven combat sports interventions (score ≥60% in methodological quality) were selected, composed of 381 older people (63% female), with a mean age of 66 years. In the selected studies, interventions based on judo, karate, and taekwondo were carried out, where it was not possible to verify the benefits of combat sports in cognitive function and electrophysiological markers of brain activity regarding active/passive control groups, although the individual results of the analyzed studies indicate that the practice of combat sports favor selective attention, divided attention, executive function, visual perception, and cognitive processing speed in older people.

CONCLUSIONS

The available evidence does not allow a definite recommendation regarding combat sports as an effective cognitive function intervention in older people.

Combat sport in the body composition of the elderly: A systematic review and meta-analysis study

OBJECTIVE

To analyze possible changes in body composition in elderly individuals with combat sports as an intervention.

METHODS

This study is characterized as a systematic review and meta-analysis. The PRISMA criteria were followed, and the study was registered in PROSPERO under the number CRD42023392613. The databases used were MEDLINE (via PubMed), Scopus, SPORTDiscus, Web of Science, and Science Direct. The risk of bias and methodological quality were assessed using Robins-I, Cochrane, and Testex tools.

RESULTS

Of the 126 publications found, 9 studies were included (5 controlled and randomized studies and 4 intervention studies). Of these studies, 6 provided data for the meta-analysis. A total of 126 publications were found and, the studies included in this systematic review had an average of 51 weeks, 3 times a week, and 50 min per session. In the results presented by the meta-analysis the variable body fat showed a reduction (SMD: -0.11; 95% CI: -0.99 to 0.09; p = 0.02; I2 = 0%).

CONCLUSION

Combat sports showed an improvement in the body composition of the elderly, with a reduction in the percentage of body fat.

Older Persons Participation in Hard Martial Arts: Opportunities to Improve Psychological Well-Being? A Scoping Review

This study aims to explore the potential psychological and cognitive advantages for older individuals engaged in hard martial arts (HMA), through a comprehensive scoping review of literature up to 2023. Specifically, it examines the extent of changes in cognition, mental state, and quality of life among elderly participants of HMA. Inclusion criteria were studies conducted on healthy persons who were over 50 years of age. Only papers published in the English language were included. The search was undertaken in electronic databases and sources of grey literature. Thirteen papers with a total of 514 participants met the inclusion criteria. Improved cognition and decreased levels of anxiety and depression were emerging themes. Together, these factors contributed to the quality of life of participants. HMA was found to benefit cognitive abilities and psychological well-being, increasing quality of life more than traditional exercise alone. Findings suggested duration of training influenced change more than frequency. The limited number of studies exploring the effects of HMA on mental wellness and cognitive ability in older adults underscores the need for further research. The findings of this review suggest cognitive and quality of life improvements and reduced depression and anxiety in individuals engaging in HMA. This review serves as a foundation for soundly designed future research.

Using Martial Arts Training as Exercise Therapy Can Benefit All Ages

Martial arts training focuses on whole-body movement patterning, philosophy, interpersonal interactions, and functional self-defense. Such training has positive impacts on physical, psychological, and cognitive well-being in older adults and children with and without clinical conditions. We hypothesize that martial arts training can be delivered as a form of exercise therapy for people at all ages to enhance overall health.

Educational Needs for Coaching Judo in Older Adults: The EdJCO Focus Groups

Judo coaches are urged to develop specific competencies and skills for addressing the special needs of older practitioners. Thus, the purpose of this study was to investigate the experts' opinions on judo training in late adulthood to develop sound educational programs for coaches of older judo practitioners. Overall, eighty-eight experts from an international consortium of judo and educational partners participated in national focus groups. During the focus groups, experts discussed five themes and generated statements pertinent to educate coaches to support older judo practitioners (e.g., benefits; necessary knowledge; risks; training groups definition; tools; and tests for monitoring training plans). The initial list of 262 statements was synthesized, validated, analyzed, and organized into a final list of 55 statements and six macro-areas: aging process (n = 10); safety and first aid (n = 6); physiology and fitness (n = 12); psychology and mental health (n = 11); organization and environment (n = 5); adapted judo teaching and training (n = 11). The present international eminence-based study, harmonizing diverse intercultural perspectives, highlighted the specific needs of older judo practitioners. The results of this study will contribute to the structure of a sound educational program for coaches of older judo practitioners to enhance the quality of older adults' sports experiences by linking safety, enjoyment, social interactions, and learning principles.

Changes in selected exerkines concentration post folk-dance training are accompanied by glucose homeostasis and physical performance improvement in older adults

The study aimed to evaluate the impact of selected exerkines concentration induced by folk-dance and balance training on physical performance, insulin resistance, and blood pressure in older adults. Participants (n = 41, age 71.3 ± 5.5 years) were randomly assigned to folk-dance (DG), balance training (BG), or control group (CG). The training was performed 3 times a week for 12 weeks. Physical performance tests-time up and go (TUG) and 6-min walk test (6MWT), blood pressure, insulin resistance, and selected proteins induced by exercise (exerkines) were assessed at baseline and post-exercise intervention. Significant improvement in TUG (p = 0.006 for BG and 0.039 for DG) and 6MWT tests (in BG and DG p = 0.001), reduction of systolic blood pressure (p = 0.001 for BG and 0.003 for DG), and diastolic blood pressure (for BG; p = 0.001) were registered post-intervention. These positive changes were accompanied by the drop in brain-derived neurotrophic factor (p = 0.002 for BG and 0.002 for DG), the increase of irisin concentration (p = 0.029 for BG and 0.022 for DG) in both groups, and DG the amelioration of insulin resistance indicators (HOMA-IR p = 0.023 and QUICKI p = 0.035). Folk-dance training significantly reduced the c-terminal agrin fragment (CAF; p = 0.024). Obtained data indicated that both training programs effectively improved physical performance and blood pressure, accompanied by changes in selected exerkines. Still, folk-dance had enhanced insulin sensitivity.

Risks and Benefits of Judo Training for Middle-Aged and Older People: A Systematic Review

This systematic overview aimed to review studies investigating the benefits and risks of judo training in older people, and to explore practical methodological applications (Registration ID: CRD42021274825). Searches of EBSCOhost, ISI-WoS, and Scopus databases, with no time restriction up to December 2022, resulted in 23 records meeting the inclusion criteria. A quality assessment was performed through the following tools: ROBINS-I for 10 experimental studies, NIH for 7 observational studies, and AGREE-II for 6 methodological studies. A serious risk of bias emerged for 70% of the experimental studies, whereas 100% of the observational and 67% of the methodological studies presented a “fair” quality. When involving 1392 participants (63 ± 12 years; females: 47%), the studies investigated novice (n = 13), amateur/intermediate (n = 4), expert (n = 4), and unknown (n = 3) level judoka by means of device-based, self-reported, and visual evaluation measures. Mean training encompassed 2 ± 1 sessions. week−1 of 61 ± 17 min for 7 ± 6 months. In relation to judo training exposure and outcomes, three main themes emerged: (i) health (56% of studies; e.g., bones, anthropometry, quality of life); (ii) functional fitness (43%; e.g., balance, strength, walking speed); and iii) psychosocial aspects (43%; e.g., fear of falling, cognition, self-efficacy). Although the included studies presented relevant methodological weaknesses, the data support the positive effects of judo training with advancing age. Future research is needed to help coaches plan judo programs for older people.

A New Developmental Approach for Judo Focusing on Health, Physical, Motor, and Educational Attributes

Judo is currently the most practiced combat sport in the world. There is no doubt of its importance for children, adolescents, adults, and seniors. However, due to its inherent complexity, coaches tend to place greater or lesser emphasis only on one of its multiple domains during the judoka formative years. The present study presents a novel developmental approach signaling Judo as an excellent way for physical, motor, educational, and health development across the lifespan. In this study, we consulted 23 Judo coaches, aiming to clarify the relevance and adequacy of the domains (Competitive, Health, Technical-Tactical, and Philosophical-Educational) and phases of the proposed model. Our findings showed that the model contents-physical, motor, educational, and health-are entwined with its four domains, which were considered of utmost importance by experts in the development of judokas. We, therefore, contend that our model is essential to better understand the growth and development of young judokas. Also, it may be a useful tool for Motor Development experts.
