Introduction: This research aimed to investigate which waves, Theta or Beta, are significant predictors of visual simple and complex reaction times during the Vienna test, using regression modeling. The research material comprised the test results of male judo athletes (n = 24), selected through mixed sampling (purposive and random). The study was conducted in two cycles, differentiated by frequency but with the same duration of EEG biofeedback sessions, in both the control and experimental groups. The first cycle of the study consisted of 15 sessions held every other day. Each training session lasted for 4 minutes. The second series of studies, which took place after a six-week break, was characterized by a higher frequency of meetings (daily), with the duration of one training session remaining the same as in the previous cycle, i.e., 4 minutes. The impact of neurofeedback training on the visual reaction speed of judo athletes was verified using selected samples from the Vienna Test System (VTS). The study revealed that athletes from the experimental group, as a result of implementing the beta1/theta protocol, statistically significantly improved their simple and complex reaction times after each training cycle. Similar changes were not observed in the control group. The results suggest that neurofeedback training may significantly improve reaction skills in a sports context. However, for a fuller understanding and confirmation of these effects, further well-controlled studies are necessary.

Introduction: The inclusion of the training process of pre-adolescent female athletes with additional means helps to optimize exercise influences. The study aims to estimate the influence of a 16-week program of handball training with medicine balls in comparison with a program of handball training on the physical and special training of beginner handball players. Methods: Female athletes were randomly divided into an experimental (n = 30; 11.23 ±0.41 years) and a control (n = 32; 10.99 ± 0.4 years) group. Training sessions of both groups were conducted according to the existing curriculum, but the experimental group replaced part of the usual regimen by training with medicine balls once a week. Results: Both groups improved, but more markedly in the experimental group than in the control group in the increase of leg explosive power (Δ% = 7.73, p < 0.05, d = 0.67), trunk muscle strength (Δ% = 16.9, p < 0.05, d = 0.88) and ball handling level indicators: dribbling the ball (δ% = 13.41, p < 0.05, d = 1.07), throwing the handball ball with one hand (Δ% = 28.6, p < 0.05, d = 1.6). Conclusions: A program of workouts with medicine balls enables the improvement of important components of physical performance. Inclusion of the training process of pre-adolescent female athletes with additional means helps to optimize exercise influences.

Introduction: Deep stabilization system (DSS) strength and endurance are crucial for injury prevention and athletic performance. Training surfaces can influence training outcomes; therefore, this study aimed to compare the impact of performing strength trunk exercises on unstable and stable surfaces with conventional trunk exercises. Materials and Methods: DSS and trunk stability were assessed before and after 10 weeks of three different training interventions among twenty elite futsal players. Each intervention included 25 strength training sessions. Pre- and post-tests encompassed various measurements, including diaphragm, trunk flexion, trunk back extension, hip flexion, intraabdominal pressure, side plank, pronation, and supination tests. Results: Conventional exercises showed a significant improvement only in the side plank test. In contrast, unstable and stable surface conditions exhibited notable enhancements in all tests, displaying superior trunk stability compared to conventional exercises. The stable surface condition demonstrated significantly greater improvements in the pronation and supination tests compared to the unstable surface condition. Conclusions: Except for the side plank test, dynamic conventional exercises did not yield substantial improvements in the assessed tests. Deep stabilization system training enhances trunk stability when performed on both unstable and stable surfaces, with unstable surfaces potentially yielding greater improvements in m. transversus stabilization functions.

The brain-derived neurotrophic factor (BDNF) rs6265 (G196A; Val66Met) polymorphism has been associated with obesity and type 2 diabetes, with contradictory results involving either A or G as the risk allele. The main aim of this study was to examine whether the BDNF rs6265 polymorphism would influence the efficiency of a training program. An additional aim was to determine whether selected polymorphism can be used as a genetic marker for obesity-related parameters. We studied the genotype distribution in a group of 160 Caucasian females in whom body mass and composition parameters, lipid profile, and glucose levels were measured before and after the 12-week aerobic training program. The majority of obesity-related parameters significantly changed during the intervention (main effect of training); however, the training response was not modulated by genotype (non-significant genotype × training interactions). We also did not find an effect of genotype on selected parameters. Our study showed that the rs6265 polymorphism does not affect the efficiency of the applied training program and is not a good genetic marker for assessing the obesity-related parameters in the studied population. However, we confirmed that regular physical activity is associated with an improvement in obesity-related parameters, which is an important observation for public health.
脑源性神经营养因子（BDNF）rs6265（G196A；Val66Met）多态性与肥胖和 2 型糖尿病有关，而风险等位基因为 A 或 G 的结果却相互矛盾。本研究的主要目的是研究 BDNF rs6265 多态性是否会影响训练计划的效率。另外一个目的是确定所选多态性是否可用作肥胖相关参数的遗传标记。我们研究了一组 160 名白种女性的基因型分布情况，在为期 12 周的有氧训练计划前后测量了她们的体重和成分参数、血脂状况和血糖水平。在干预期间，大多数与肥胖相关的参数都发生了显著变化（训练的主效应）；但是，训练反应并不受基因型的影响（基因型 × 训练的交互作用不显著）。我们也没有发现基因型对选定参数的影响。我们的研究表明，rs6265 多态性不会影响应用训练计划的效率，也不是评估研究人群肥胖相关参数的良好遗传标记。不过，我们证实，经常进行体育锻炼与肥胖相关参数的改善有关，这对公共卫生来说是一个重要的观察结果。

Introduction: Childhood obesity is a major health problem especially for schoolchildren both physically and mentally. The study was conducted to assess the effects of the structured physical activity (PA) program on the physical fitness (PF) and self-perception levels of obese schoolchildren. Materials and Methods: A total of 67 students aged 9-11 were recruited and the experimental group (n = 27) was attended to exercises once per week for 60 mins for 12 weeks. Self-perception Scale for Children and PF tests were applied as pre- and post-tests. Results: 12-week PA sessions improved obese schoolchildren’s self-perception levels in general self-worth, athletic competence, and social competence subdimensions. Fitness levels were also improved. Body mass index (BMI) and body fat percentage (PBF) were affected positively and the increase in experimental group’s BMI and PBF were minimal when compared to the obese (n = 20) and non-obese controls (n = 20). Aerobic fitness and muscular endurance components were significantly improved better than obese and non-obese controls. Conclusions: It was found that attending 12-week PA sessions improved obese schoolchildren’s PF and self-perception components. As a result, it is recommended that the time allocated for PA sessions in schools should be increased and attendance of the obese schoolchildren to PA should be promoted.

Introduction: The aim of this research was to examine the relationships of four perceived teaching styles (i.e., autonomy support, structure, control, and chaos) of physical education (PE) teachers with students’ satisfaction of psychological needs as well as autonomous and controlled motivation towards physical activity in PE and leisure time context. Materials and Methods: 320 students (166 boys and 154 girls) aged from 12 to 18 years old (M = 14.13, SD = 1.6) participated in the study. In this cross-sectional study, participants filled in a questionnaire of study variables. A variance-based structural equation model was employed to test the study hypotheses. Results: Autonomy support is indirectly related to students’ autonomous motivation towards physical activity in leisure time via satisfaction of a psychological need and autonomous motivation for PE (β = 0.18, p < 0.01). Structuring the teaching style is indirectly related to students’ autonomous motivation towards physical activity in leisure time via satisfaction of a psychological need and autonomous motivation for PE (β = 0.21, p < 0.01). Conclusions: When a PE teacher employs an autonomy-supportive and structuring teaching style, it is likely to satisfy students’ psychological needs and increase autonomous motivation towards physical activity in PE, which, in turn, may enhance autonomous motivation towards physical activity during leisure time.

Introduction: The present study aims to compare the effects of massage, selected yoga exercises and massage-yoga combination methods on symptoms of depression. Materials and Methods: According to the research criteria, 60 available samples were selected and randomly divided into three experimental groups and single control one. The Beck Depression Inventory was completed by the examinees before the intervention, two months after its beginning and one month after ending. Each experimental group received one of the massage interventions, selected yoga exercises and massage-yoga combination for eight weeks, three sessions per week and for a period of 40 minutes per session. The data were analyzed using 4 (group) × 3 (measurement) factorial analysis of variance method (ANOVA) and Bonferroni post hoc test was employed to compare the intragroup differences in the measurement steps and intergroup ones. The significance level of alpha was considered to be 0.05. Results: The results showed that there was a significant difference in the level of depression within the three experimental groups of massage (0.001), yoga (0.00) and combination (0.00). There was also a significant difference between the four groups in the depression variable (0.001). But the combined exercise program of massage and yoga had the most effect in improving the symptoms of depression. Conclusion: The results of this research showed that all three methods of massage intervention, selected yoga exercises and the combination of massage and yoga led to the improvement of depression symptom. However, there was a significant difference between the three approaches and the massage-yoga combinative exercise program was found to have the greatest effect on functioning of people with depression.

Introduction: Range of motion (ROM) of resistance exercise affects the muscle damage magnitude and the recovery-time course. Thus, the main aim of this study was to compare conventional and extended ROM in the bench press exercise on neuromuscular fatigue assessed by velocity changes during bench press throw, as well on the exercise-induced muscle damage evaluated by creatine kinase (CK) activity in the blood. Material and Methods: A total of fourteen healthy, well-trained males performed 5 sets of the bench press exercise at 70% of one repetition maximum with either standard (STD) and cambered (CMB) barbell until reaching volitional failure. CK and barbell velocity changes were assessed at the baseline and 1h, 24h, 48h post exercise protocol. Results: The results showed that higher peak barbell velocity was reached during the bench press throw after the CMB when compared to the STD condition. Moreover, CK activity showed an overall significant growing trend from baseline to time points following exercise during the STD, whereas the CMB post-48h CK was higher in comparison to pre and post, but not than post-24h. Conclusion: the bench press exercise performed with the use of CMB barbell might not require a specific training approach, and even higher training frequency might be applied.

Introduction: This study, based on the self-determination theory (SDT) by Deci and Ryan (1985), investigates the motivation among outdoor life students at universities and colleges in Norway. It also examines how students score on basic psychological needs, such as autonomy, competence, and relatedness, and their frequency of engagement in outdoor activities. The significance of the nature experience and the activity itself for the outdoor life students were analyzed, along with the extent to which the SDT can explain these two variables. Material and methods: The participants completed two standardized questionnaires. Results: The results showed a high degree of internal motivation and the most autonomous forms of external motivation, in addition to a high score on basic psychological needs. The students state that both nature experience and activity are important to them, with the former being the most important. Conclusions: The most active students in outdoor activities state that competence is an important basic psychological need. The importance of natural experience is mainly explained by a high score on self-determination as a psychological need, in addition to a high score on the most autonomous external motive: integrated regulation. Internal motivation is the main explanation for the importance of the activity for students.

It also examines how students score on basic psychological needs, such as autonomy, competence, and relatedness, and their frequency of engagement in outdoor activities. The significance of the nature experience and the activity itself for the outdoor life students were analyzed, along with the extent to which the SDT can explain these two variables. Material and methods: The participants completed two standardized questionnaires. Results: The results showed a high degree of internal motivation and the most autonomous forms of external motivation, in addition to a high score on basic psychological needs. The students state that both nature experience and activity are important to them, with the former being the most important. Conclusions: The most active students in outdoor activities state that competence is an important basic psychological need. The importance of natural experience is mainly explained by a high score on self-determination as a psychological need, in addition to a high score on the most autonomous external motive: integrated regulation.

Introduction: This study aimed to assess the mental condition of aquatic athletes during COVID-19 lockdowns and identify factors that could predict changes in their emotions and mood disturbances. Materials and Methods: The sample was composed of 506 competitive swimmers (ages 15-36) in four aquatic specializations, with 82.4% competing at the national level. Data was collected through questionnaires between April 10th and May 1st, 2020. Results: Female athletes had higher levels of unpleasant mood states and were generally more vulnerable to the lockdown's harmful effects. Team athletes had higher levels of friendliness, which may be a coping strategy for difficult situations. Training conditions played a significant role in mental health, with athletes who trained more having fewer mood disturbances. Lack of training negatively impacted fitness and mental health. Conclusions: The study emphasizes the importance of providing support to athletes during pandemics and reducing stigmatization around seeking psychological support.
