INVESTIGATION OF STABILITY OF THE TRUNK AND LOWER LIMBS AMONG BALL PLAYERS
Views:824The 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.

THE RELATIONSHIP BETWEEN DECISION-MAKING AND GAME INTELLIGENCE WITH BASKETBALL STATISTICS
Views:990Introduction: basketball is one of the most popular teams sports worldwide. It is generally regarded as the second most popular sport globally, with around 450 million registered players (RÁTGÉBER et al., 2019). The attention, decision-making, interaction with the participants, and recovery of a basketball player are complex. It can be influenced by internal and external factors as well as by different stimuli. The current mental and physical state of athletes affects their performance. Experience, reception and adaptation of developmental stimuli determine performance during the game. Cognitive abilities, executive functions, and inhibition are all psychological processes that can help or hinder concentration. It is essential to assess and measure to enhance sports performance and provide objective support for our subjective assumptions. Many technical and tactical elements characterize basketball, but it is also essential to have relevant motor and affective skills when making decisions. Players need to adapt to sudden and varied stimuli and make the most intelligent and appropriate decision to achieve a positive outcome. Live statistics may indicate the effectiveness of decision-making during the game. In the present study, we analyzed the results of the Color-Word Interference Test and Trail Making Test prior to and after the games.

Examining the Correlation Between Speed and Change of Direction Running Speed (CODS) in Football
Views:13The correlation between speed and change-of-direction running speed (CODS) remains unclear, as indicated by the results of previous research. One reason may be that researchers have used different tests to investigate the speed of running with a change of direction (CODS), where the number of direction changes, the angle, the total length of the running test, and the time required to complete the test vary. The researchers agree that agility is not the same as straight-line running speed, but suggest that further studies are needed to determine the relationship. Regarding the relationship between speed and agility, the results showed a consistent trend that faster players tend to perform better on the agility test. Still, we could only statistically confirm this at 20 and 30 metres. Only for the agility test in the right direction was there a significant correlation between 20 and 30 meters alone. Our results indicate that both agility and and CODS require different developmental stages.

THE EFFECT OF ROUTINE DYNAMIC WARM-UP MODIFICATION ON SPEED, AGILITY, AND MUSCLE ENDURANCE IN AMATEUR FEMALE FOOTBALL ATHLETES
Views:307Football prioritizes physical aspects such as speed, agility, strength, flexibility, and muscle endurance. With women's growing interest in football in Indonesia, it is becoming increasingly clear that an excellent physical condition is necessary. Therefore, good physical condition will also impact the risk of injury and, most importantly, performance on the field. Thus, the main aim of this study was to evaluate the effects of Dynamic Warm-Up modification for six weeks on several physical performances, such as (running, change of direction speed, and muscle endurance) in female amateur soccer players. This prospective study involved a modified routine dynamic warm-up program intervention, three times a week warming up before the training session with details of the intervention implementation time, namely 18 times, excluding the initial and final tests. At the start, the players demonstrated dexterity and tests of speed, agility, and muscle endurance, and the test was carried out again at the end of the program intervention. The results show that the significance value of the 30 m Sprint test is 0.083 > 0.05, meaning there is no program influence on the speed component. Furthermore, the significance value of the Illinois Agility test is 1,000 > 0.05, meaning the program does not influence the agility component. Then, the significance value of the wall sit test is 0.083 > 0.05, meaning that the program does not influence the agility component. This study concluded that modifying the dynamic warm-up routine could not improve physical performance, namely speed, agility, and muscle endurance in female soccer players.

EXAMINATION OF EXECUTIVE FUNCTIONS AFFECTING SPORTS PERFORMANCE IN THE CONTEXT OF ATHLETE EXPERIENCE
Views:691Introduction: 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.

MAXIMIZING JUMP PERFORMANCE: THE ROLE OF PLYOMETRICS IN YOUTH FOOTBALL TRAINING
Views:482Vertical jump training is a fundamental method for the physical conditioning of athletes. The synergy of motor skills exhibited during such movements substantially contributes to achieving motor acts and actions with higher performance indices. In football, vertical jumping, like other specific factors, is an essential element that can determine the outcome of a match. Football players need to be physically prepared to handle any complex situations that may arise during a game.
Our study aims to evaluate the impact of plyometric training on vertical jump height performance in young football players.
A total of 16 subjects, U11 football players, were randomly assigned equally into a PL group (N=8), which followed a plyometric training routine for 6 weeks, and a control group (N=8), which followed the routines set by the club team's coach. They were evaluated in two phases – an initial and a final phase – using Optojump testing equipment. The results obtained were compared using statistical and mathematical methods of descriptive analysis, the Shapiro-Wilk test for normality distribution, and the Independent Samples T-test.
Additionally, Levene's test was used to analyze the type of variances in the distributions.
Our study confirmed that a customized plyometric training routine can significantly improve vertical jump performance, considering age-specific characteristics.
Our investigations suggest that integrating this type of training into the subjects' routines can bring significant benefits to the development of motor skills, specifically to young football players, offering exciting perspectives for optimizing their performance in the long term.

COMPLEX PERFORMANCE ANALYSIS IN BALL SPORTS
Views:1122Assessing athletes' capabilities has never been as widespread as it is nowadays. Several methods have evolved and developed in recent decades to measure physical or mental skills accurately. However, these assessment protocols became more and more specific. They focused on a certain attribute, as if we forget that athletes' game performance is not equal to the total of different skills. Since psychomotor skills interact during games, test protocols should be similar and measured comprehensively. Two groups of ball sport players, thirteen soccer players (n=13) and ten handball players (n=10), have been tested on the SpeedCourt training system to find a relationship between the results of two tests (Micromovement Test, MT) and traditional indicators, such as Heart Rate Recovery (HRR), Body Mass Index (BMI) and Body Fat Percentage (BFP). Furthermore, the correlation in performances of the two groups has also been analyzed. We found no significant correlation between the two MT and HRR results (r=0,5132 and r=-0,5588). Similarly, there are significant correlation neither MT and BMI (r=-0.0886 and r=-0.0174) nor MT and BFP results (r=0.0872 and r=-0,2399). A significant difference cannot be found between the MT results of the two groups that indicate that MT applicable for both sports.

THE APPLICATION OF NEUROFEEDBACK TRAINING IN ELITE YOUTH FENCERS
Views:438During our research, we applied neurofeedback training to youth fencers. We investigated the effects of the six-week intervention program on the mental toughness, stress tolerance and executive functions of teenage epee fencers.
We used the validated Muse 2 EEG-based Teamflow system, the Sport Mental Toughness Questionnaire, Electrogastrographic Stress Holter (MDE Heidelberg, MSB MET Balatonfüred) and the internationally recognized stress test of the Vienna Test System (Schufried, Vienna).
The practical benefit of neurofeedback training can be seen in its application as a complementary method, as this innovative protocol can help enhance the performance of the athlete. However, the international literature is not clear about the effect of neurofeedback training
In conclusion, the improvements can be observed in mental toughness and psycho-physiological indicators, but negative changes can also be observed in several parameters in both subjects. Various other psycho-physiological factors need to be taken into account, since our pilot study included two participants.

THE INVOLVEMENT OF ADVANCED COGNITIVE SKILLS IN VARIOUS FOOTBALL – SPECIFIC TESTS A PILOT STUDY
Views:337Sports professionals should encourage the development of cognitive functions as often as possible in training. Stimulating the brain with alternating stimuli can promote concentration, attention, and the development of situational awareness and decision-making skills. The more and more diverse stimuli the player receives, the faster and more effectively he will react to match situations. Our research examined the effect of exercises requiring advanced cognitive skills on the training load. Changes in cardiovascular data were monitored using Polar Verity Sense 4J and Polarflow systems. The pilot study involved a U-16 football player. Our results demonstrated that in addition to increasing speed, duration, and number of repetitions, the gradual inclusion of decision-making situations can also effectively increase the load. The participant completed two sets of exercises. During the second test, more complex exercises required advanced cognitive skills. The average heart rate for the first test was 130 beats per minute. We experienced an increase in the average value (150 beats per minute) during the completion of the second test. We measured an average 15 percent increase in the participants' heart rate.

EFFECTS OF THE MULTISPORT ACTIVITY PROGRAM ON YOUTH FOOTBALL PLAYERS’ MOTOR SKILL DEVELOPMENT
Views:402Objective: Our study aimed to compare the dynamic leg strength, acceleration, running speed, agility, and ball-handling skills of young football players.
Material and method: Forty-two players members of the Szeged-Csanád Grosics Academy participated in the so-called "Multisport Activity Program" (SG) (nsg=42), whereas the control group (CG) involved players from the academy's partner clubs (ncg=109). Our testing procedure included: standing long jump, 10 m, and 30 m run, COD 505, and T-Test with ball dribbling.
Results: We found that the dynamic leg power of the SG players was significantly improved. The means of the T-tests demonstrated (p<0.001) improved ball dribbling skills in the SG group. We found no significant difference in the COD 505 test results. The results of the standing long jump, 10 m, 30 m, COD 505, and ball control tests are strongly correlated; however, none explain the minor COD difference.
Conclusion: It is beneficial for players to participate in multisport sessions involving various agility and ball control tasks. The COD 505 test results demonstrated smaller differences between dominant and non-dominant sides in SG participants. We suggest they are less likely to develop unilateral movement patterns that lead to overtraining injuries. The results indicate that implementing a "Multisport activity program" benefits youth athlete.

EXAMINATION OF FUNCTIONAL MOVEMENT STATUS, INJURY HISTORY AND SPECIFIC MOTOR PERFORMANCE AMONG YOUNG ELITE FOOTBALL PLAYERS
Views:622Purpose: The primary aim of this study was to find any relationship between total and selected FMS scores, recent (within two years) injury status, and specific motor performance. The secondary purpose of the study was to examine, wheather is there any relationship between injuries of the hamstring muscle and injuries of the hip and knee joints of the body.
Material and methods: Youth and junior football players were volunteered to take part in our examination. A total of 45 subjects participated in our study, their age varied from 16 to 19. We implemented a five to one scoring system to identify the status of injuries. Finally, a complete FMS testing and a single leg (unilateral) standing long jump test were performed, involving all participants.Beside evaluating the total FMS scores of the participants, we chose to specifically stress on five test batteries out of seven. Out of the five tests we further focused on three FMS tests.
Results and conclusion: In this given population, we have not found significant relationship between total FMS scores and overall scores (5 to 1) of injury status. Our results also did not indicate any significant correlation between selected FMS scores and single leg standing long jump performance.

THE RELATIONSHIP BETWEEN FLOW PRONENESS, ACHIEVEMENT MOTIVATION AND LOCUS OF CONTROL AMONG DUAL CAREER ATHLETES
Views:449Achieving peak performance is strongly connected to athletic flow experiences, and it is also considered one of the main goals in professional sports. For this reason, it essential to systematically examine any contributing factor connected to athletes’ flow proneness. This study examined the assumed connection between flow proneness, achievement motivation, and locus of control among dual-career athletes. Furthermore, the universality of sport flow experiences was also tested. We used Oláh’s (2005) Flow Questionnaire, Rotter’s (1966) Internal-External Locus of Control Scale, and the Achievement Motivation Test developed by Lang and Fries (2006). The test was shared online by the snowball method, and the sample consisted of 178 dual career athletes. According to the results, there is a significant connection between flow proneness, achievement motivation, and locus of control. The universality of flow was also proven.

CHANGES IN SPINAL RANGE OF MOTION AFTER 16 WEEKS TRAINING PROGRAM IN PUBERTAL CHILDREN
Views:429The aim of the present research was to improve the neglect behavior of pubertal children in an intervention program. Within the framework of the program, the main function of the spinal column and the strength and extensibility of the muscles responsible for posture were investigated. The participants included in the study are 7th grade children of the Neumann János Elementary School in Szombathely, Hungary, (nb=7); (ng=10). The Idiag M360 Spinal Mouse was used to investigate the physiological curvatures and main function of the spinal column before and after the program. The device was used to examine the children's spines in standing, bending forward and again in a standing position after the Matthiass test was performed. Pre-intervention (1) and post-intervention (2) data showed significant decreases in all assessed characteristics and similar increases in sacrum to hip ratio (Sac/Hip) (9.83±4.36 - 21.63±4.39); p<0.000. The greatest change was found in the Th11/12 dorsal vertebral body angles (4.50±2.05 - -0.30±0.25); p<0.000. As a result of the postural improvement program, the degree of pelvic tilt and, in parallel, the physiological curvature of lumbar lordosis was reduced to within the age-specific reference values.

COMPARATIVE ANALYSIS OF COGNITIVE ABILITIES STRESS TOLERANCE AND DECISION-MAKING PROCESS IN NOVICE AND EXPERIENCED ATHLETES
Views:723Introduction: 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 novice / 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.

GROSS MOTOR SKILLS AND PHYSICAL ACTIVITY LEVEL: IS THERE ANY GENDER DIFFERENCES IN NINE YEARS OLD CHILDREN?
Views:400Proper growth and development of young school children require mastering different skills, especially gross motor skills - basic locomotor and manipulative skills. It is essential to monitor the physical activity of nine-year-old children necessary for further proper development and healthy habits, which will continue into adulthood. This study aims to determine physical activity level, BMI, and gender differences in the performance of gross motor skills in children aged nine years (± six months). The study involved 40 participants (20 girls and 20 boys). Their body height, body weight,
and body mass index were 140.46 ± 5.72 cm; 37.84 ± 8.21 cm; and 19.09 ± 3.56, respectively. All participants completed the Physical Activity Questionnaire for Children and performed the Test of Gross Motor Development, Second Edition (TGMD-2), and two sub-tests of BOT-2 (Speed and Agility and Upper-Limb Coordination). T-test for independent samples was used to compare groups according to physical activity level (physically active and inactive group) and explore interactions with gender and BMI, and gross motor skills variables. F-values, p-values, and partial eta squared (ɳ2) values were reported as MANOVA outcomes. The results showed a significant difference between physical activity level and locomotor skills but not in manipulative skills. Further research should focus on various exercise programs that contribute to developing skills and participation in organized physical activity of children of different ages.

A STUDY ON WORD ASSOCIATION WHEN TEACHING THE THEORETICAL RULES OF VOLLEYBALL IN PHYSICAL EDUCATION
Views:679Physical Education as a subject – much like other subjects – has its own literary and educational content and the primary goal is the transference of that knowledge. In this respect, it is but one subject. At the same time it is unique, being the only subject dedicated to improving the body and the physique, yet “when we talk about the internal values of physical education, we only refer to its own literary and educational content. The meaning of this phrase includes the system of movement-based activities as well as the related intellectual knowledge” (RÉTSÁGI, 2011). During a Physical Education lesson students learn and practice movement-based activities, the importance of which is to improve their motor abilities, physical fitness (MÜLLER et al., 2013. MÜLLER et al., 2017) and mental health (BORBÉLY – MÜLLER, 2008). It may facilitate the prevention of numerous deformities or ailments, thus contributing to the preserving and of one’s health (MOSONYI et al., 2013., MÜLLER, 2015). For the past few years, multinational food companies (e.g. Danone and Nestlé) have also realized this, as they began to promote various programmes to support the regular physical activities of schoolchildren (RÁTHONYI – ODOR – RÁTHONYI, 2016). Physical Education in schools can only be considered effective if students come to appreciate and begin to feel the need for regular physical activities. For that purpose PE lessons are needed to be filled with content that is serious, requires effort (i.e. it should be a challenge that inspires improvement), but at the same time, it provides every student with feelings of success and enjoyment. This work, which at many times adapts to vastly different students (i.e. differentiates), is the duty of sports specialists and PE teachers (H. EKLER, 2013).

COMPARATIVE ANALYSIS OF INTENSE MULTIDIRECTIONAL MOVEMENTS IN YOUTH HANDBALL AND SOCCER PLAYERS
Views:1445Modern 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 movements 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.

PSYCHOLOGICAL STRESS MONITORING USING INVASIVE AND NON-INVASIVE METHODS IN ATHLETES
Views:662Introduction: The quality of performance is essential both in everyday life and in competition. In sports science (also), we have to think of the man in a complex way as a bio-psycho-social unit. In addition to changes in ECG HR and blood cortisol levels, gastrointestinal tract movements are also associated with stress management (FUKUNAGA et al., 2000) (VIANNA - TRANEL, 2006), which plays a crucial role in determining the quality of performance. Several preclinical trials have formed the basis of our research (SZŰCS et al., 2018).
Objective: Based on our earlier research and literature reviews, we would like to test and participate in validating a new method that can monitor the effects of stress on humans in real-time, in a non-invasive way, with quantitative results. In addition to GI monitoring, cortisol levels are measured invasively in the subjects, so we hope to obtain complex results.
Methods: n = 13, athletes, male = 11, female = 2, mean age 22 +/- 1,031 years. Our protocol was 115 minutes, in which we distinguished four stages (rest, stress, latency 1, latency 2). We use two methods to measure stress. One is the blood cortisol level (ELISA), and the other is the MDE Heidelberg Stress Holter (EGG), which is an innovative measurement tool capable of simultaneously examining several parameters (Small Intestine, Colon, Stomach, ECG HR). The VTS DT package was used as a stressor.
Result: Based on the complex results of the EGG, we can conclude that the Small Intestine, Colon, and Stomach motility, as assessed by the Power Spectrum (PS) Fold Change (FC) calculation, increased together under stress, and then latency decreased together over time. However, the rate of change in cortisol levels showed that most participants adapted the stressor as eustress so that its value decreased linearly.
Conclusions: Innovative measurement and evaluation methods are well utilized, as they can communicate many measurement data in a valid, real-time, non-invasive way, with a parallel display. These data and results will be used in athlete selection, mental training, elite sports, neuro-biofeedback, and health preservation.

EFFECTS OF CORE-PROPRIOCEPTIVE TRAINING ON THE QUALITY OF EXECUTIVE FUNCTIONS IN U13 FEMALE BASKETBALL PLAYERS
Views:676Introduction: 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 study 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.

PHYTOCHEMICAL SCREENING OF ANCHOTE (COCCINIA ABYSSINICA (LAM.)) AND EFFECT OF EXTRACT VIA AEROBIC EXERCISE ON ENDURANCE PERFORMANCE
Views:232Many aspects affect sports performance, and nutrition may be one of the most important. The study aimed to examine the phytochemical composition and assess the impact of supplementing Anchote (Coccinia abyssinica (Lam.)) with aerobic exercise on the endurance performance of the Mattu Kenema male football club.
Eighteen players from the Mattu Kenema football team were chosen based on an experimental research methodology. The selected athletes were divided into three groups at random: the supplement group (SG = 6), the aerobic exercise group (AG = 6), and the supplement with the aerobic exercise group (SAG = 6). Every day, members of the SG group took an Anchote (Coccinia abyssinica (Lam.)) supplement, while AE spent 45–60 minutes exercising aerobically. SAG took both interventions for 12 weeks. Pre-tests and post-tests were conducted on all parameters, such as the 12-minute run test and push-up.
The phytochemical screening result of Anchote (Coccinia abyssinica (Lam.)) extract showed the presence of various secondary metabolites such as phenol, flavonoid, tannin, glycoside, steroid, and terpenoids. The proximate composition of this extract indicates the higher content of carbohydrates (69%) and the lower fat value (2.1%).
Based on the study, 12 weeks of Achote (Coccinia abyssinica (Lam.)) consumption combined with aerobic exercise was thus shown to improve players' fitness levels at Mattu Kenema male football club. Based on the findings, Anchote (Coccinia abyssinica (Lam.)) supplement associated with aerobic exercise would enhance endurance performance due to the extract's secondary metabolites such as flavonoid, tannin, and phenol.

INFLUENCING FACTORS OF SPORT VOLUNTEERING AMONG EU CITIZENS
Views:264If there were a ‘country of volunteers,’ it would be one of the most populous countries in the world, with almost 1 billion people involved in some form of volunteering worldwide. Volunteers play an essential role in the smooth running and operation of sports associations and the performance of the assigned tasks. Our research examines the extent to which they contribute to volunteering along with different socio-demographic variables. For our analysis, we used data from the European Commission in December 2017 in 28 European Member States (28,031 people). We used ten independent factors that may influence participation in volunteering. We examined by chi-square test whether there was a relationship with the performance of sports volunteering for the selected variables. Subsequently, incorporating all these variables into a logistic regression model, we estimated how much it contributes to volunteering. The significance level was p <0.05. Based on the results of the bivariate correlation study, gender, age, life satisfaction, frequency of sports, education, type of residence, and social status, social status significantly influences participation in sports volunteering (p <0.001). Based on a multivariate correlation study, demographic, quality of life, sports, socio-cultural, and socioeconomic variables significantly influence volunteering (p <0.001). Our research has demonstrated that participation in sports volunteering is affected by several factors. Our research did not cover the study of motivational factors of athletes.

OVERVIEW OF THE CURRENT METHODS OF SKELETAL MUSCLE INJURY TREATMENT
Views:663Voluntary 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.

THE EFFECT OF GOALS ON THE DEVELOPMENT OF THE YOUTH BASKETBALL PLAYERS’ CONTROL PLACE AND THE SOURCE OF MOTIVATION
Views:561Our study conducted research on the motivation of the basketball players of the Debrecen Basketball Academy (U11 - 76 basketball players) and on which factors play and define it, especially the control sites and their goals are related to the assessment of performance development. For this purpose, the target studies were based on such a follow-up procedure, which performs monitoring, and target studies on the development of physical endurance could be detected. Our results show that both the quality of choice (how complex tasks are undertaken with athletes in the study) and the evolution of the control site and the source of motivation are among the factors in developing athletes ’goals. The result showed that many objective measurement tools and test procedures are available to coaches and sport-psychologists to assess and evolve athletes’ peak performance. At the same time, further practical improvements can be made by changing training methods and introducing additional motivating factors.

Differences Between Standard and Sport-Specific Countermovement Jumps in High-Performance U18 Male Water Polo Players: A Cross-Sectional Study
Views:19Introduction: Vertical jump capacity is essential for evaluating lower-limb performance in water polo, especially under dryland testing conditions. While power or force is often implied, jumping height remains the primary measurable outcome in these protocols. Aim: This study aimed to compare vertical jump performance in U18 male water polo players using two jump types: the standard Counter-movement Jump (CMJ) and a modified "Frog Style" CMJ (CMJ-Frog), hypothesizing that the latter better reflects sport-specific lower-limb mechanics. Materials & Methods: A cross-sectional, within-subjects design was employed on a sample of 39 male water polo players from the Under-18 category (mean height: 183.02 ± 5.43 cm; mean weight: 75.20 ± 10.41 kg). Each athlete performed three maximal trials of two jump protocols: the standard Counter-movement Jump (CMJ) and the modified sport-specific CMJ-Frog. Jump height was measured using the OptoJump Next system. Data analysis comprised descriptive statistics and normality assessment using the Kolmogorov–Smirnov test. Inferential statistics were conducted via paired-samples t-tests to compare protocols within subjects, with effect sizes calculated using Cohen's d. Results: CMJ-Frog jumps yielded significantly higher values (37.43 ± 4.59 cm) than standard CMJs (34.17 ± 4.49 cm), t (38) = -7.46, p < .001, with a large effect size (d = 1.19). Conclusions: The CMJ-Frog style may serve as a more functionally relevant assessment for evaluating vertical jump capacity in Under-18 male water polo players, as it better reflects the mechanics of aquatic elevation during gameplay. It may offer a more specific alternative for performance testing and monitoring in aquatic athletes. Future studies should validate the CMJ-Frog protocol in senior players and investigate its relationship with in-water performance metrics.

RELATIONSHIP BETWEEN NIGHT-TIME DYSPNEA EPISODES AND HEART RATE VARIABILITY
Views:745Purpose: 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.
Methods: 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.
