THE RELATIONSHIP BETWEEN DEMENTIA AND PHYSICAL ACTIVITY: A SYSTEMATIC REVIEW
Published March 20, 2020

Introduction: Many studies have already shown that, there is connection between physical actitity and cognitive functions. Therefore, the aim of our research is to examine the relationship between cognitive decline (dementia) and physical activity.

Method: The research genre was a secondary method analysis.... The literature review was primarily collected from articles published on international scientific sites.

Results: A total of 11 reviews were examined, examining the relationship between dementia and physical activity, which included 217 articles. Research has supported our hypothesis, that regular exercise has a positive effect on the prevention of dementia by reducing the risk of dementia.

Conclusion: It would be worthwhile to further investigate, which types of exercise at what repetition rate and what intensity achieve the best results in reducing the risk of dementia, or slowing the process of dementia.

EFFECTS OF CORE-PROPRIOCEPTIVE TRAINING ON THE QUALITY OF EXECUTIVE FUNCTIONS IN U13 FEMALE BASKETBALL PLAYERS
Published July 11, 2022

Introduction: Complex scientific work to investigate and develop the factors determining performance is essential to improving sports performance. Creating the neuro-muscular connection is paramount, as it is the cornerstone of movement coordination, and the nervous system is the key to mental components.

Objective: Our stu...dy aims to demonstrate the positive effects of core-proprioceptive training on executive functions.

Method: The DEAC U13 girls' academy basketball players (n=12) participated in a 9-week core-proprioceptive training program. Before and after the program, the players' executive functions were measured with the Vienna Test System.

Result: A marked improvement in the measured parameters regarding the evolution of correct and incorrect responses and the reaction time. There is a significant reduction in the number of missed responses.

Conclusions: Core-proprioceptive training also improved nerve-muscle connectivity, affecting the quality of executive functions. The results may be implemented in designing training program.

EXAMINATION OF EXECUTIVE FUNCTIONS AFFECTING SPORTS PERFORMANCE IN THE CONTEXT OF ATHLETE EXPERIENCE
Published July 6, 2022

Introduction: In our research, we investigated the components, executive functions, and cognitive abilities underlying decision-making in sports performance using a computer-based test system. To define the athlete experience, we classified athletes according to an exact, unambiguous definition following international terminology, based on ...their performance, achievement, playing age, and sport's popularity. We hypothesize that team athlete with significant athletic experience will perform better on the executive function test. 

Methods: A cross-sectional study was conducted on team athletes N=52. The VTS-DT test was used to measure executive function. The classification of athlete experience was based on an internationally accepted taxonomy defined with scientific precision (SWANNN, 2015). 

Results: When classified by athlete experience, the athletes we studied fell into amateur and elite categories. The DT/S2 scores of the two groups were compared based on each factor. We obtained trend-like correlations for the factors 'number of reactions', 'number of stimulations,' and 'number of good responses. Correlation analysis was performed between the factors on a group-by-group basis. When examining the relationship between reaction time, we found that there is a strong relationship with the number of stimulations (amateurs: r = -0.80; elite athletes: r = -0.87) since the faster someone is (i.e., the less reaction time), the more times they can respond to stimulations. Looking at the results for elite athletes, we also observe a moderately strong relationship between reaction time and the number of good responses (r = -0.68). We may suggest that experienced athletes could produce better responses faster than less professional athletes.

Conclusions: Our hypotheses were partially confirmed, as we found a trend-like correlation that elite athletes scored higher on the DT test, which examined athletes' executive functions in a complex, adaptive way. Our research demonstrates that, on the one hand, it is worthwhile for coaches to build on experienced athletes when assembling a team, in addition to the momentum of young athletes, and that the development of executive functions and cognitive skills can improve the performance of athletes.

COMPARATIVE ANALYSIS OF COGNITIVE ABILITIES STRESS TOLERANCE AND DECISION-MAKING PROCESS IN NOVICE AND EXPERIENCED ATHLETES
Published June 1, 2021

Introduction: Cognitive skills are essential in team sports. Perception, decision-making (tactical thinking, learning, attention, thinking, emotions), stress tolerance, and even the level of motor and technical-tactical skills all affect performance.

Objective: We found a significant difference in stress tolerance of novic...e / young and experienced team sport players (BALOGH, DONKA 2020). Our results showed that experienced athletes have higher level of  stress tolerance.  However, as this was a descriptive study, we intended to support our statement involving more number of subjects, and an analysis of cognitive abilities.

Method: A cross-sectional experimental study was performed on 41 male and 13 female team sport (handball, volleyball and football) players. We used the VTS DT software package for cognitive abilities and the MDE Heidelberg StressHolter (gastro, HR, TH, GSR) for stress measurement. During the 35-minute measurement process, a state of rest was measured in the first stage, a response to a 10-minute stress situation (VTS-DT for the cognitive test) in the second stage, and a state of rest and latency in the third stage.

Results: We found a significant relationship between stress tolerance and the cognitive ability of female and male participants. Our results demonstrated that football players had a lower level of  stress tolerance than other team sport players. They also tent to make more mistakes in the VTS-DT test.

Conclusions: The classification into novice and experienced categories need to be done more uniformly in the future. We are aware of it, that the unequal number of participants by sports, is one of the limitations of our study. However, it is encouraging that significant results demonstrate a strong relationship between stress tolerance and the number of appropriate decisions. These results reveal other areas of research for us.
