Acute Effects of Post­Activation Performance Enhancement of 5RM Weighted Pull­Ups and One Arm Pull­Ups on Specific Upper Body Climbing Performance.

This study aimed to compare the acute effects of performing two kinds of pull-ups: traditional, pronated grip pull-ups performed with two arms and additional weight with loading intensity of 5RM and one-arm pull-ups, on specific upper body climbing power. Twenty-four advanced climbers participated in the study. The International Rock Climbing Research Association (IRCRA) Power Slap Test was chosen to assess specific upper body climbing power. All athletes performed the test under three conditions: control (without a conditioning activity) and both kinds of pull-ups as conditioning activities. Results revealed significant improvements in the Power Slap's distance, power, velocity, and force in 5RM weighted pull-ups, but not in one-arm pull-ups. In the latter case, participants reached higher power values after the conditioning stimulus, but the effect size was small. Also, the differences with the remaining variables (power, speed, and force) were non-significant. The results suggest that weighted pull-ups with a 5RM intensity and not one arm pull-ups seem to be an effective PAPE stimulus. Therefore, the former can be used as a conditioning activity before an explosive climbing exercise such as the Power Slap on a campus board.

Local Governments Spending on Promoting Physical Activity during 2015-2020: Financial Data and the Opinion of Residents in Poland.

INTRODUCTION: The COVID-19 pandemic has significantly affected local governments involved in sports and recreation in designated areas. The unprecedented scale of the spread of the disease has led to increased research in the area of the disease, considering various correlations. However, little has been written about the impact of the pandemic on local government spending on recreation and sports services in Poland. OBJECTIVE: The purpose of the article is to assess the level of local government involvement in the implementation of sports and recreation in Poland compared to other European Union countries, as well as changes in this level in connection with the emergence of the COVID-19 pandemic in the opinion of respondents. METHODOLOGY: In the study, the data regarding expenditures of local government units on recreational and sporting services collected in the Statistical Office of the European Union (EURO-STAT) for 2015-2020 were used. The survey portion was conducted among 1600 respondents who provided answers on a 5-item scale that addressed local government involvement in promoting physical activity among residents during COVID-19. RESULTS AND CONCLUSION: Local government spending on recreational and sporting services in Poland between 2015 and 2019 increased by about 38%, from EUR 1524.7 million in 2015 to EUR 2103.5 million in 2019. This spending in 2019 was about 40% higher than the average for European Union countries. In contrast, in 2020 it amounted to more than EUR 1886 million and was more than 10% lower compared to the previous year (2019)-the pre-pandemic period. Despite the obstacles caused by the COVID-19 pandemic and budgetary constraints, cities in Poland took several measures in 2020 to maintain the current pace of development and strived to maintain the status of modern, green, and open, betting on balanced development also in aspects related to sports or culture. It was shown that the opinion of respondents mostly coincided with the existing financial state-in voivodeships where there had been a decrease in spending related to sports and recreation compared to the pre-pandemic period, residents are worse at assessing the activities of local governments related to promoting physical activity.

Prevalence of Emotional Eating in Groups of Students with Varied Diets and Physical Activity in Poland.

BACKGROUND: Emotional eating (EE) is not a separate eating disorder, but rather a type of behavior within a group of various eating behaviors that are influenced by habits, stress, emotions, and individual attitudes toward eating. The relationship between eating and emotions can be considered on two parallel levels: psychological and physiological. In the case of the psychological response, stress generates a variety of bodily responses relating to coping with stress. OBJECTIVE: Therefore, the main objective of this study was to evaluate and compare the prevalence of emotional eating in groups of students in health-related and non-health-related fields in terms of their differential health behaviors-diet and physical activity levels. MATERIAL AND METHODS: The cross-sectional survey study included 300 individuals representing two groups of students distinguished by their fields of study-one group was in health-related fields (HRF) and the other was in non-health-related fields (NRF). The study used standardized questionnaires: the PSS-10 and TFEQ-13. RESULTS: The gender of the subjects was as follows: women, 60.0% (174 subjects) (HRF: 47.1%, n= 82; NRF: 52.9%, n = 92); men, 40.0% (116 subjects) (HRF: 53.4%, n = 62; NRF: 46.6%, n = 54). The age of the subjects was 26 years (±2 years). Based on the results of the TFEQ-13, among 120 subjects (41.4%) there were behaviors consistent with limiting food intake (HRF: 72.4%; NRF: 11.0%), while 64 subjects (20.7%) were characterized by a lack of control over food intake (HRF: 13.8%, 20 subjects; NRF: 27.4%, 20 subjects). Emotional eating was characteristic of 106 students (37.9%), with the NRF group dominating (61.6%, n = 90). It was observed that a high PSS-10 score is mainly characteristic of individuals who exhibit EE. CONCLUSIONS: The results obtained in the study indicate that lifestyle can have a real impact on the development of emotional eating problems. Individuals who are characterized by elevated BMI values, unhealthy diets, low rates of physical activity, who underestimate meal size in terms of weight and calories, and have high-stress feelings are more likely to develop emotional eating. These results also indicate that further research in this area should be undertaken to indicate whether the relationships shown can be generalized.

Prevalence of Orthorexia in Groups of Students with Varied Diets and Physical Activity (Silesia, Poland).

(1) Background: The literature emphasizes the role of many factors influencing the onset of eating disorders (EDs) and their mutual influence on each other. Therefore, this study aimed to evaluate and compare the prevalence of orthorexic behaviors in groups of health-related and non-health-related students in terms of their differential health behaviors-diet and physical activity levels. (2) The study included 300 individuals representing two equal groups of fields of study, which for the study were called the health-related field (HRF) and the non-health-related field (NRF). (3) Results: Based on the results of the dietary assessment, it was found that the best dietary model was characterized by the HRF group; in this group, 97.2% of students were characterized by a very good and good dietary mode. The NRF group, on the other hand, was dominated by a sufficient dietary mode for 64.4% of all cases in this group (94 people), while the dietary model marked as "good" was less popular, at 24.6% of this group (36 people). (4) Conclusions: Based on the cited self-research and information from the literature, it can be concluded that the problem of orthorexia is still a new issue at the level of social sciences, medical sciences, and health sciences. The psychometric tools used in this study allowed us to demonstrate the prevalence of the aforementioned eating disorders in the sample groups of students.

Selected Behaviors and Addiction Risk Among Users of Urban Multimedia Games.

Introduction: The rapid development of technology has led to the transfer of entertainment to the virtual world. Many games and multimedia applications use the so-called augmented reality. With the development of a new technological branch, a new health problem has emerged, which is infoholic addiction, attracting people with the specific functionality that is cyberspace and the virtual world. Objective: The study aimed to assess health behaviors and the risk of addiction among users of urban multimedia games. Research methodology. The study was conducted among players 1,134 of urban multimedia games-Pokemon GO, in the period March-June 2021. A 990 correctly completed questionnaires were included in the final analyses. The author's questionnaire was used in the study, which included two standardized measurement scales in the Polish abbreviated version: a questionnaire of emotions and sensations associated with electronic entertainment and a questionnaire on addiction to electronic forms of entertainment. Statistica 13.0 program was used for statistical processing of the data. The probability level was p < 0.05. Results: The profile of the gamer was identified as male, aged 18-30 years, with secondary education (more rarely higher), not in a relationship, living in a city of more than 100 thousand inhabitants-60.1% of gamers met these criteria. Respondents played urban multimedia games daily (84.7%). About 26.3% of respondents played this type of game 2-3 h a day. In terms of physical fitness, 64.3% of respondents felt that physical fitness had improved as a result of playing multimedia urban games. In terms of mental condition, most of the respondents said that nothing had changed (55.3%). It was observed that 72.3% of respondents had some risk of addiction to urban multimedia games. Conclusion: Users of urban multimedia games were usually adult men living in big cities. It was also shown that the defined profile of the player was characterized by a higher risk of addiction to electronic forms of entertainment. It was observed that the respondents most often played urban multimedia games every day in a maximum of two-hour sessions. Based on the tools used, it can be concluded that the study group was characterized by a certain risk of addiction to urban multimedia games.

Aggression Dimensions Among Athletes Practising Martial Arts and Combat Sports.

Purpose: The main aim of the research was to analyse aggression dimensions among athletes practising martial arts and combat sports. Material and Methods: There were 219 respondents. The Buss and Perry Aggression Questionnaire (BPAQ) in the Polish adaptation by Siekierka was applied. Results: Martial arts apprentices turned out to present a statistically significantly lower level of hostility (p < 0.001) and of the general aggression index (p = 0.04) than combat sports athletes. It turned out that lower level of aggression was noted in female participants (physical aggression (p < 0.001), verbal aggression (p = 0.004), hostility (p < 0.001), and the general aggression index (p < 0.001). Analysis revealed that the training experience and the training rank did not differentiated the level of the respondents' particular aggression dimensions. Conclusions: It would be advisable to perform parallel analyses in other areas of Poland and take into account the respondents' education and place of residence.

Beta-Alanine Supplementation and Sport Climbing Performance.

BACKGROUND: Supplementing ß-alanine (BA) improves exercise performance in efforts that are highly dependent on anaerobic glycolysis. As it has not yet been established whether it relates to climbing, the current study aimed to investigate the effects of BA on climbing-specific performance. METHODS: Fifteen elite climbers performed intermittent high-force high-velocity campus board exercise, and two bouldering traverses, hard and easy. They ingested 4.0 g·d-1 BA or placebo for four weeks in a double-blind, pre/post experimental design. RESULTS: In the campus board trial, ANOVA revealed a tendency toward significance (p = 0.066). Post hoc analysis revealed that there was a significant (p = 0.002) and "large" (d = 1.55) increase in the total number of "slaps" in the BA group. No significant supplementation × group interaction was found in "hard" traverse and a significant interaction for mean changes in number of moves (p = 0.025) and in time to failure (p = 0.044) on an "easy" traverse. Post hoc analysis revealed that only the BA group significantly improved from baseline in number of moves (+9.5) and time to failure (+32 s). Effect sizes were d = 1.73 and d = 1.44, respectively. CONCLUSIONS: Four weeks of BA supplementation can improve performance during continuous climbing lasting about 1 min and repeated bouts of upper body campus-like movements. However, it failed to enhance climbing of a shorter duration.

Post-activation Potentiation Response of Climbers Performing the Upper Body Power Exercise.

The purpose of this study was to determine a performance-enhancing effect of post-activation potentiation (PAP) stimulus on climbing-specific upper body power exercises, measured by the IRCRA Power Slap test on a campus board. Two groups of climbers performed the test under one of two conditions: without initial pre-loading (control group) or after 5RM (repetition maximum) pull-ups (PAP group). The test was performed at four time points: at baseline (PRE) and after 4 (POST4), 6 (POST6), and 8 (POST8) minutes of a PAP stimulus (PAP group) or after the same rest period lengths (control group). The results showed that post-baseline slap distances were significantly greater in the experimental group while no change was seen in the control group [repeated measures ANOVA: F ( 3,42 ) = 6.26, p = 0.001]. Post hoc analysis revealed no significant difference between any of the post-baseline trials in both groups. The mean improvement in the first POST4 test in the experimental (PAP) group was +6.5 cm (6.8%). The results of the present study suggest that PAP might be beneficial for acute improvement of upper body power performance in climbers. Therefore we conclude that such stimuli might be advisable for climbers as a part of the warm-up before bouldering competitions and training as well. They might also offer a stronger stimulus for climbers working on power development.

The Safety of the Neighborhood Environment and Physical Activity in Czech and Polish Adolescents.

(1) Background: An increase in or at least the sustainment of walking activities across a wide section of the population is a crucial health-related task for Central and East European countries. The aim of this study was to assess the associations between adolescents' walking activities and various levels of perceived safety of the built environment in differing socio-demographic backgrounds of Poland and the Czech Republic. Furthermore, we aimed to determine major moderators affecting the walking habits of adolescents in areas with different levels of walkability. (2) Methods: The surveys were conducted during the 2008-2009 and 2013-2014 school years in 24 Polish and 35 Czech secondary schools, with a sample of 2001 adolescents. All participants completed the International Physical Activity Questionnaire-Long Form and the NEWS-Abbreviated. Selected students took part in objective weekly monitoring of physical activity (PA). (3) Results: Boys and girls who perceived their neighborhood environment as the safest were significantly more likely to meet the recommendations for leisure-time walking. Adolescents from the safest environment achieved 11,024 steps/day on average, while those from the least safe environment achieved 9686 steps/day. (4) Conclusions: A safe neighborhood environment significantly predicts walking activities among girls. Environmental safety improvement can support the active transport and better use of leisure time PA.
