An external focus of attention enhances table tennis backhand stroke accuracy in low-skilled players.

The aim of the study was to determine the impact of internal and external (proximal and distal) attentional focus on table tennis backhand stroke accuracy in low-skilled players. Fifty-one undergraduate physical education (PE) students were randomly assigned to 3 groups: Group G1 (IF) was instructed to focus on the hand holding the paddle, Group G2 (EFP) was instructed to focus on the ball, while Group G3 (EFD) was instructed to focus on targets marked on the tennis table. The experimental groups followed identical instructions except for the instruction about the focus of attention. Participants were asked to score as many points as possible by hitting the ball inside the three smallest targets marked on the tennis table. They were required to do so using a backhand stroke. The practice session consisted of 45 trials in three blocks of backhand (15 trials at each target). A special scoring system was used to determine the accuracy of the strokes. One of the most important findings from the current research was that groups with an external focus of attention revealed significant improvements in accuracy in the post-test, while the group with an internal focus of attention achieved low training effects. No significant difference was observed between G2 (EFP) and G3 (EFD) in the delayed retention test, which indicates that proximal and distal attentional focus had similar effects on table tennis backhand stroke accuracy in low-skilled players.

Effect of Coronavirus 19 on Maintaining Balance in Skilled Athletes.

Preliminary studies have reported that motor control is negatively impacted following an infection of COVID-19. The purpose of this study was to evaluate the effect of COVID-19 on maintaining balance in highly skilled athletes. As part of a larger investigation that was initiated in 2019, twelve professional handball players were recruited to participate in a study that was designed to measure static balance performance. Following the initial pre-test, six participants (body height 184.8 ± 4.7 cm; body weight 85.5 ± 3.3 kg; age 21.3 ± 1.2 years) were infected with COVID-19. The remaining six participants (body height 188.7 ± 2.6 cm; body weight 92.3 ± 3.7 kg; age 26.3 ± 3.3 years) never tested positive for COVID-19 and were presumably not infected with the virus. The experimental design required all the participants to complete an initial balance assessment (pre-test) and a later balance assessment (post-test). To fully analyze our data, we conducted a 2 (condition: COVID, no-COVID) X 2 (test: pre-test, post-test) ANOVA with repeated measures on the second factor. Our analysis revealed that the skilled athletes who contracted COVID-19 had a significant decrease in balance performance from the pre-test that occurred prior to being infected with COVID-19 relative to the post-test that occurred following the COVID-19 infection. Additionally, the skilled athletes who were not infected with COVID-19 did not demonstrate the same deterioration in balance performance in the same period. This study highlights the impact COVID-19 has on static balance performance in a group of highly skilled handball players. Longitudinal studies are needed to fully understand the lasting impacts COVID-19 has on motor behavior.

Study and evaluation of physical activity of youth from the Visegrad countries in relation to the WHO recommendations

Background: In recent years, the subject literature has provided concrete recommendations concerning health with regard to specific parameters. Therefore, it is necessary to indicate appropriate physical activity standards for proper development at various stages of human ontogenesis. Objective: The aim of the work was knowledge of the level of physical activity of high school youth in the Visegrad countries, including gender indications, to demonstrate whether the WHO recommendations are fulfilled. Material and methods: The research was conducted in students from four Visegrad countries: the Czech Republic, Poland, Slovakia and Hungary. As the research method, the International Physical Activity Questionnaire − IPAQ in the extended version was used. Results: Boys seem to do much better and have largely fulfilled the WHO recommendation for high-intensity efforts performed 3 times for 20 minutes, and medium and high efforts − 7 times for 60 minutes, which is particularly crucial for the effectiveness of the level of physical activity. Conclusions: It is indispensable to continue monitoring the physical activity of young people using modern research techniques. It seems intentional to intensify promotion and educational activities, which should be aimed at motivating young people to undertake physical activity in accordance with world-wide recommendations.

Level of and Factors Determining Physical Activity in Students in Ukraine and the Visegrad Countries.

Background: Examining the level of physical activity in students is a vital issue as these young people are the future social elite. Methods: The research was conducted in the years 2013⁻2016 and comprised 5008 males and females, mean age of 20.5 ± 2.1 years, including 2237 (55.3%) students from students from Eastern European National University, Lutsk, and Ternopil State Medical University, Ukraine, as well as 2237 (44.7%) from the Visegrad countries, i.e., University of Pécs in Hungary, University in Kosice, Slovakia, University of Olomunec in the Czech Republic and the State School of Higher Education in Biala Podlaska, Poland. It applied a diagnostic survey-the extended version of the International Physical Activity Questionnaire (IPAQ), supplemented with original questions regarding body weight, height, self-assessment of physical fitness and amount of leisure time. Results: The comparison of students' PA from selected European countries, members of the Visegrad group and Ukraine, is particularly vital to the latter country as it demonstrates a different level of socio-economic development. There was noted a significantly higher level of physical activity in students from the Visegrad countries than in Ukraine. Further, there was an overall lower level of physical activity in females compared to males. What was positive about the studied samples was a healthy BMI index in the majority of the male and female respondents, with a significantly higher indicator in Ukraine. Conclusions: Among the factors significantly affecting higher physical activity in both researched samples were the BMI and high self-assessment of physical fitness. There was no significant variation in the level of physical activity and the amount of leisure time, both in those studying in the Visegrad states and Ukraine.

Differences in physical activity and nutritionand silhouette-related behaviours in male and female students in selected European countries.

INTRODUCTION: As indicated by the WHO, lifestyle plays a unique role in human health, which in turn is determined to a great extent by physical activity and nutrition. It must be borne in mind that physical activity should be systematic and regulated by an age-appropriate exercise intensity. All this indicates that learning about students' lifestyle, with a particular focus on physical activity is vital as it these young people who aspire to the role of the future elites. OBJECTIVE: The aim of the study is to evaluate the level of physical activity, nutrition- and silhouette-related behaviours of male and female students to assess the relationships between these variables in students from the Visegrad Group countries. MATERIAL AND METHODS: The study was conducted in 2015 and involved 2,497 students attending three undergraduate levels aged - x - 21,76, (SD-1,80) - 1,211 males (48.5%) and 1,286 females (51.5%). The IPAQ long-form and a questionnaire by the Polish Chief Sanitary Inspector were used. RESULTS: Physical activity was significantly higher in male than female students. An important relationship was observed among the larger number of consumed meals, level of physical activity, and silhouette-related behaviours in male students, which was not the case with females. However, there was an important correlation between physical activity in males and females who exercised to increase or decrease body weight (musculature), and took medications to increase body weight (musculature). CONCLUSIONS: Both males and females showed pro-health attitudes related to the level of physical activity and nutrition- and silhouette-related behaviours.
