In the complex and changing situation on the soccer field, players must always be aware of their teammates, opponents, and the position of the ball during the game, constantly updating and analyzing the strategic information of the opponent in order to make appropriate tactical decisions. This ability to track multiple objects at the same time is also a prerequisite for high-level soccer players to be able to react quickly and appropriately during the game. Therefore, it is essential to examine the attentional ability of soccer players in dynamic scenarios. This study compares soccer players’ performance in 2D planar and 3D virtual reality dynamic tracking tasks in two dimensions. They are correct tracking rate and tracking speed. This paper examines the tracking performance and spatial attention allocation characteristics of soccer players in different dynamic tracking tasks and the differences with the average college students by manipulating different types of 2D dynamic tracking tasks and incorporating a point detection paradigm. It was found that there were no differences in correct tracking and detection stimulus awareness between soccer players and college students in different 2D dynamic tracking tasks, showing consistency across populations. In terms of correct tracking rates, both soccer players and university students showed the highest correct tracking rates in the location MIT task, followed by the MOT task, and the worst in the identity MIT task. This indicates that the good dynamic attention ability of soccer players was not reflected in the above 2D dynamic tracking process. However, soccer players and college students showed consistent characteristics across populations in different dynamic tracking tasks. The results of detection stimulus awareness showed that soccer players and college students had the same trend of attention allocation between dynamic tracking tasks, i.e., more attention to the blank area of the screen and the target object and less attention to the distractor. This suggests that there was a distractor suppression effect between different dynamic tracking tasks.

Cyberbullying is a major youth social problem over the world and it has been associated with a variety of negative outcomes. However, few studies investigated how offline peer victimization affect cyberbullying and the potential relations between family factors and cyberbullying remains unknown. The current study addresses this gap in knowledge by examining the victimized by peers is associated with higher moral disengagement which further promotes college student’s bullying online. A three-wave longitudinal study, each wave spanning six months apart, was conducted in a sample of 521 Chinese college students (Mage = 22.45, SD = 4.44, 59.3% girls). Results of moderated mediation model shown that peer victimization at T1 predicted more cyberbullying at T3 through moral disengagement at T2, after controlling for demographic variables and cyberbullying at T1. T2 moral disengagement significantly mediating the association between T1 peer victimization and T3 cyberbullying. In addition, high level of negative parenting strengthened the effect of moral disengagement at T2 on cyberbullying at T3. The prevention and intervention for both offline and online bullying victimization are discussed.

Despite significant advances in the treatment and rehabilitation of stroke, level of post-stroke disability remains at a fairly high level. Recent innovative developments in the rehabilitation of these patients provide good results in terms of functional outcome. One of such developments is method of virtual reality (VR), which affects not only the speed and volume of regaining movement, as well as coordination, but also normalizes the psycho-emotional background, increasing the motivation of patients to improve the recovery process. This article provides a literature review of the use of the VR method in the rehabilitation of post-stroke patients, neurophysiological aspects of recovery of lost functions using this method are considered.

Ergogenic Supplements

<b><i>Background:</i></b> Soccer is an extremely competitive sport, where the most match important moments can be defined in detail. Use of ergogenic supplements can be crucial to improve the performance of a high-performance athlete. Therefore, knowing which ergogenic supplements are important for soccer players can be an interesting strategy to maintain high level in this sport until final and decisive moments of the match. In addition, other supplements, such as dietary supplements, have been studied and increasingly referenced in the scientific literature. But, what if ergogenic supplements were combined with dietary supplements? This review brings some recommendations to improve performance of soccer athletes on the field through dietary and/or ergogenic supplements that can be used simultaneously. <b><i>Summary:</i></b> Soccer is a competitive sport, where the match important moments can be defined in detail. Thus, use of ergogenic supplements covered in this review can improve performance of elite soccer players maintaining high level in the match until final moments, such as creatine 3–5 g day<sup>−1</sup>, caffeine 3–6 mg kg<sup>−1</sup> BW around 60 min before the match, sodium bicarbonate 0.1–0.4 g kg<sup>−1</sup> BW starting from 30 to 180 min before the match, β-alanine 3.2 and 6.4 g day<sup>−1</sup> provided in the sustained-release tablets divided into 4 times a day, and nitrate-rich beetroot juice 60 g in 200 mL of water (6 mmol of NO3<sup>−</sup> L) around 120 min before match or training, including a combination possible with taurine 50 mg kg<sup>−1</sup> BW day<sup>−1</sup>, citrulline 1.2–3.4 g day<sup>−1</sup>, and arginine 1.2–6 g day<sup>−1</sup>. <b><i>Key Messages:</i></b> Soccer athletes can combine ergogenic and dietary supplements to improve their performance on the field. The ergogenic and dietary supplements used in a scientifically recommended dose did not demonstrate relevant side effects. The use of various evidence-based supplements can add up to further improvement in the performance of the elite soccer players.

AbstractPurpose. The aim of the study was to determine differences in anteroposterior spine curvatures between futsal players, soccer players, and non-training students. The results may contribute to the development of present-day knowledge of posturometry, and its implementation in training can help reduce the risk of body posture disorders in athletes. Methods. The examined group consisted of 48 athletes and 38 non-training college students. Body posture parameters were measured with the use of Posturometr-S. The normality of distribution was checked with the Shapiro-Wilk test, and the differences between the groups were measured with ANOVA and the Bonferroni post-hoc test. The level of statistical significance was set at p < 0.05. Results. The analysis of angle values revealed the widest and most similar measurements in the group of futsal players and soccer players. The analysis of variance proved statistically significant differences between the soccer players and futsal players (p = 0.003). The difference between the soccer players and non-training students was statistically significant. The highest γ angular value was measured in non-training students, followed by futsal players and soccer players. The statistical analysis revealed significant differences between the non-training students and futsal players, as well as non-training students and soccer players (p < 0.001). Conclusions. A complex assessment of athletes’ body posture is crucial in injury prevention. Training overloads may often lead to disorders of the organ of locomotion and affect the correct body posture in athletes. This, in turn, may result in pains and injuries.

Escape rooms exist in various forms, including real-life facilities, board games, and digital implementations. The underlying idea is always the same: players have to solve many diverse puzzles to (virtually) escape from a locked room. Within the last decade, we witnessed a rapidly increasing popularity of such games, which also amplified the amount of related research. However, the respective academic landscape is mostly fragmented in its current state, lacking a common model and vocabulary that would withstand these games' variety. This manuscript aims to establish such a foundation for the analysis and construction of escape rooms. In a first step, we derive a high-level design framework from prior literature. Then, as our main contribution, we establish an atomic puzzle taxonomy that closes the gap between the analog and digital domains. The taxonomy is developed in multiple steps: we compose a basic structure based on previous literature and systematically refine it by analyzing 39 analog and digital escape room games, including recent virtual reality representatives. The final taxonomy consists of mental, physical, and emotional challenges, thereby providing a robust and approachable basis for future works across all application domains that deal with escape rooms or puzzles in general.

Introduction: As long as the world is still in a pandemic, an individual must maintain his mental health to deal with problems or impacts arising from a pandemic situation. The growth mindset is believed to be a predictor in influencing a person's mental health. We tested how the growth mindset influences on positive mental health in college students during a pandemic. Method: A total of 567 students from universities in Indonesia randomly completed an online questionnaire. The data collection tool uses Positive mental Health and Implicit Theory Measures scale on two dimensions of growth mindset: intelligence mindset and moral mindset. Results: The results show that the intelligence mindset affects positive mental Health, the moral mindset as well. In addition, the two variables together, intelligence mindset and moral mindset, affect positive mental health. Conclusions: The three hypotheses proposed can be accepted statistically, but the magnitude of the influence of each hypothesis is very small. The implications and research suggestions are discussed in depth in the discussion.

We built and validated a Chinese version of the Tolerance for Mental Pain Scale-10 (TMPS-10). Participants were 840 college students in Jilin, China. The TMPS-10 consists of two dimensions: managing the pain and enduring the pain. In our study Cronbach's alphas were .80 and .83, respectively, and test–retest reliability coefficients were .78 and .72, respectively, for these two dimensions. Exploratory factor analysis results demonstrate that the two dimensions accounted for 61.58% of the total variance. Confirmatory factor analysis results show that the two-factor model fit the sample data well. As the Chinese version of the TMPS-10 meets the requirements for a psychometric tool, it can be used to evaluate Chinese college students' tolerance of psychological pain.

Objectives: Under the background of entrepreneurship, college students have obvious entrepreneurial advantages and become the main force in the entrepreneurial army. Universities actively respond to the call of the state. Methods: In recent years, they have continuously expanded their enrollment, which has made many students exposed to higher education courses and increased the knowledge reserve of Chinese students. Entrepreneurial psychological quality refers to a kind of psychological quality level which is formed and continuously developed and matured under the influence of people’s entrepreneurial environment and corresponding society. Results: It is a reflection of people’s psychology and behavior. In the actual process of entrepreneurship, due to the lack of social experience and entrepreneurial psychological quality, it is often difficult for college students to achieve the desired goals, often ended in failure. It is important to cultivate the psychological quality of college students. Conclusion: Based on this, this paper constructs the cultivation path of College Students’ innovation and entrepreneurship psychological quality by improving the innovation and entrepreneurship health education curriculum, improving the psychological consultation mechanism, and doing a good job of psychological health dynamic tracking.
