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.

Introduction: Dementia has now grown to become a "folk disease", making it a very important area of ​​research. After reviewing several studies, it is also accepted that regular physical activity (MAKRA - BALOGH, 2018) (DONKA - BALOGH, 2018) tends to have a positive effect on cognitive abilities and neurodegenerative disorders rather neutrally or negatively. Because this disease involves a decline in cognitive abilities, it is imperative that special attention be given to improving the number of years of life and the quality of treatment.Objective: We would like to get a comprehensive picture of the methods and tools used to measure dementia.Method: Reviewing and summarizing the related articles in the literature according to the criteria we have defined (type of measurement, relation of measurement methods, number of measurements). Review.Results: In our research, we found many measuring tools that are suitable for measuring and testing dementia. Most measurements are made using two or more measuring devices combined to provide more accurate and complex results for dementia. It can also be stated that more practical forms of measurement are used today, and in this topic, paper-pencil tests are only used as accompanying measurements, as a confirmation in most studies.Conclusions: There are many measuring tools available for testing dementia. We have to choose the one that suits us best.

Introduction: The study of dance and cognitive abilities is a common research topic today, as well as many studies and articles on the aspects of physical activity and cognitive relationships. Studying the topic is essential, as the two components actively influence our performance and quality of life, regardless of gender, age, or... education

Objective: To examine the effect of dancing activities has a beneficial effect on motor and cognitive abilities. Furthermore, to investigate the interaction of dance and dementia. Researching exercise programs that do not worsen or accelerate the processes associated with aging, but help to stagnate dementia at that time.

Method: For analysis, we used an overview of English and Hungarian studies focusing on dance and dementia from Google Scholar and Research Gate.

Results: According to most research articles, various dance therapies have an impact on cognitive abilities, and studies have shown that dancing exercise programs (either in pairs or solo) do not impair the health of people with dementia. Many studies do not provide accurate test data, which would be extremely important as further research is conducted.

Conclusions: First, there is a significant relationship between cognitive function and physical activity. On the other hand, there are no specific procedures, exercise programs, or measurement methods that can improve dementia.

Purpose: We wanted to assess the values of expected night-time and day-time variability of the heart rate, in the presence of dyspnea episodes during night-time, recorded by a Holter monitor.

Objective: Our aim was to investigate whether nocturnal breathing disorders affect the HRV indexes.

Method...s: 40 patients participated in our survey. 20 of them experienced episodes of night-time breathing difficulty, and the control group consisted of 20 participants in whose case there were no episodes of night-time breathing difficulty. We were examining the domains of time and frequency of heart rate variability, using day-time and night-time values recorded by a 24-hour Schiller Medilog Holter monitor. We evaluated the distribution of the parameters with a continuous codomain, their typical distribution and expected values on histograms, and summarized them in a table. For the examination of the difference in averages the Two-Sample T- Test was used, where p<0.05.

Results: The vegetative equilibrium ratio and the standard deviation of the R-R intervals showed a significant difference between the apnea patients and the healthy group at night. Examining the severity of apnea, we didn't find significant difference between the two groups in the mean of the time and frequency indices, however, a decrease in the values of the apnea group was observed compared to the control group.

Conclusion: Night differences in the vegetative equilibrium rate and time parameters of the apnea patients and the control group, as well as differences in the HRV index recorded by the change in the severity of the disease, draw attention to the importance of the HRV indicators with HOLTER monitors.

Voluntary contractions of skeletal muscle made up of striated muscle tissue cause body movements and are well controlled. One of the most characteristic features of skeletal muscle is its high in vivo and in vitro regeneration capacity, but with greater muscle loss, the regeneration process is exhausted and requires intervention support. It... follows that muscle injury is a constant challenge for the clinic. In the last century, especially in the last few decades, a number of techniques have been developed to promote muscle regeneration, including various surgical techniques, physical therapy, biomaterials, muscle tissue cultivation, cryotherapy, magnetic field application and cell therapy. At the same time, there is still a great need to develop new methods and materials that promote skeletal muscle improvement and functional regeneration. In this study we give a comprehensive picture of the epidemiology of muscle tissue loss, highlight current strategies for clinical management, and discuss new methods of muscle regeneration and the challenges of their future clinical transformation.

Physical activity and exercise are especially important in maintaining health and reducing risk of many diseases. Exercise leads to a pronounced immunomodulation by affecting the elements of innate immune system, as well as the ratio and functions of neutrophils, macrophages, natural killer cells, which are involv...ed in the development, maintenance and elimination of inflammation. In the adaptive immune system, Th1 / Th2 balance shift toward Th2, and high-intensity training causes an increase in the proportion of regulatory T cells, as opposed to the effect of non-strenuous exercise on the Treg cell ratio. In response to exercise, there is a lack of data on B cells, but some studies have reported a decrease in immunoglobulin secretion. In our own research we observed changes in naive and memory B cell ratios. Upon exercise, IL-6, as proinflammatory cytokine, promotes T cell proliferation, activation, and differentiation of B cells into antibody-producing plasma cells. Hormonal factors play an important role in the background of immunological changes. Exercise stimulates the secretion of both adrenaline and noradrenalin, and their concentration in the blood is directly proportional to the duration of exercise. Endurance exercise is associated with increased cortisol levels, while low intensity exercise does not significantly affect cortisol levels. Exercise and physical stress can increase the concentration of endorphins by 3 to 10 times; β-endorphin inhibits T and B cell activity, thus reduces antibody production. Testosterone causes a reduction in antibodies to IL-4, IL-5, IFN-γ, Ig-M and Ig-G. Based on the above, mild to moderate physical activity contributes to the enhancement of immune reactivity and the immune response. On the other hand, strenuous exercise with increased intensity leads to a deterioration of immune function and impaired immunological defense.

Modern soccer is characterized by short distance multidirectional movements. Elite level players execute a large number of micromovements of all kinds. Like in handball game situations in soccer usually occur in small areas. We investigated, whether soccer players may be able to perform accelerations, decelerations, intense starting movemen...ts and turns at the same level as handball players. We utilized the Speed Court movement analysis system to prove our hypotheses. We measured youth athletes, they executed two testing protocols. High-quality speed, agility, spatial awareness, and decision-making capabilities were required by the participants. We designed two protocols called the “60-meter chase”, and the “30-second chase” to mimic the situations tend to occur in a game. Each participant was asked to perform the test protocols three-times, we registered the best try, after 12 weeks of practice, the athletes repeatedly executed the two protocols. We also performed a body composition analysis, which demonstrated similar data for the two groups. We concluded that soccer players were able to perform at the same level as handball players, some of them even outperformed their counterparts.

The technical background of the various ball games is determined by its lower endpoint and ultimately provides a coordinated functional assurance of its muscles. The activity of the superficial and deep abdominal muscles is a function of the moving, kicking, jumping limbs, and the supporting, limiting and stabilizing functions of the supporting... limb. A basic element of injury prevention is the operation of stabilizers. During the health check, routine testing options should be checked and a targeted intervention program developed.

 The aim of the research program was to measure the core and lower final stabilization functions of ballplayers - basketball players, water polo players, and soccer players - by classifying and analyzing the various technical knowledge into three groups, as well as statistical classification and analysis of the target groups.

 We tested U16 water polo, basketball and soccer players. A musculoskeletal comparative study was performed specifically with an examination of the stability of the torso and the lower limb, with special tests. Internationally Used Standard Tests: Single Leg Squat test (sec.), Single Leg Squat on TOGU test (sec.), Single leg wall-sit test (sec.) Single leg wall-sit with a ball (sec.), do a standard test with different results.

 The results are known because of their full scope, the development of muscle synergism needs in a given sport. Developing and launching a unified intervention program for further goals and then compiling, with the subsequent involvement, a statistical element to end the friendship.

 Developing the results and considering the technical background, determine the effectiveness of the exercise program, that is, a functional approach-based exercise program that needs to be introduced into the body and the final determination of the synergistic function from a special test position bank.
