Characteristics of the techniques of skilled female junior athletes in 10 km race walking
No full textThe paper presents the major kinematic characteristics of thetechniques of skilled female junior athletes in 10 km race walking (n= 20, number of results – 32). Comparative analysis of athletes withdifferent level of sports mastery has been carried out. It has beenrevealed that for the level of results of x = 50:29 (S = 01:14), theaverage velocity at distance segments constitutes 3.30 m·s–1 (S =0.09), the average index of stride length is equal to 1.02 m (S =0.03), whereas the stride frequency and support phase duration –3.24 stride·s–1 (S = 0.10) and – 0.282 s (S = 0.013), respectively.The angle of foot placement was equal to 70.48º (S = 3.22), whereasthat of take-off – 58.09º (S = 1.93)
Eating disorders among athletes: systematic review
No full textEating disorders in the sports community are increasingly common, yet still considerably hidden diseases. Over the past decades, studies have shown a higher prevalence of eating disorders among athletes than in the general population. The risk of suffering an eating disorder differs in relation to gender, characteristics, and sports categories. The review article summarizes the available information on eating disorders in relation to endurance sports. The author also categorizes and identifies the risk factors leading to an eating disorder, common for both the general population and athletes.

Review of the book title: recommendations for increasing physical activity after the covid-19 pandemic
No full textRecommendations for Increasing Physical Activity after the COVID-19 Pandemic focuses on the importance of physical activity, especially after the pandemic, which significantly impacted the lifestyle of many people. The book starts with an analysis of the pandemic's effects on people's physical habits, highlighting a decline in physical activity and an increase in sedentary behaviour. It is followed by recommendations and practical exercises aimed at helping individuals improve their physical fitness and overall health. The book provides a detailed examination of how lockdowns and other restrictions led to decreased physical activity. This section is well-supported by data and scientific studies. The author includes practical guidelines for various types of exercises that are accessible to the general public. Detailed descriptions and step-by-step instructions on how to perform these exercises are included.

Dependence of mechanical power and pulse rate of mountain bikers on bicycle tire pressure
No full textThe study aims to analyse the effect of tyre pressure on the mechanical performance and pulse rate of cyclists while riding a mountain bike uphill. Tire pressure can significantly affect driving characteristics and affect the amount of mechanical work required to reach a certain speed. In our research, we looked at how different tyre pressures (1 bar, 2 bar and 3 bar) affect the mechanical performance and pulse rate of cyclists when riding uphill. The research sample consisted of Slovak performance mountain bikers from 16 to 23 years of age, who regularly participate in races at the national level. The probands completed three timed uphill rides with a duration of about 11 minutes and 30 seconds. The section was 1.55 km long with an average gradient of 11%. The probands maintained a constant speed of 8 km/h during the timed section. To evaluate the results, we used arithmetic mean, maximum, minimum, Shapiro-Wilk test, paired T-test and Wilcoxon test. The results showed a statistically significant difference in mechanical performance at different tire pressures, with the highest power having to be exerted at a pressure of 1 bar. The pulse rate also varied statistically significantly depending on the tire pressure, with the highest values recorded at the lowest pressure (1 bar). These results suggest that optimal tire pressure can improve athletic performance and reduce physiological strain when driving uphill.

Longitudinal body composition changes of youth female football players
No full textThe development of women's football requires specific knowledge about football players, which undoubtedly includes knowledge about body composition. The aim of the paper was to describe the development of the body composition of youth female national football players. A total of 136 national female football players under 15 category participated in this study. The body compositions of female football players was monitored by single-frequency BIA device (Omron BF-511, Kyoto, Japan) and was conducted during national football camps throughout 6 years (2017-2022). We did find significant differences in comparison between individual years of birth of female football players in body fat (p=0,001) and skeletal muscle (p=0,001). Changes observed between birth years 2008 and 2003, 2004 and 2005 were 3-6% decrease in body fat and 2-4% increase in muscle mass (p < 0.05). We can state a trend of development in body composition in terms of a decrease in body fat and an increase in muscle mass of WU15 female football players in the Slovak national team during 6 years. This finding indicates an improving trend in the body composition of female football players in Slovakia.

Comparison of modern and traditional coaching styles in ice hockey
No full textOur study focuses on comparing the modern coaching style with the traditional style by examining the efficiency of training sessions designed by us. Additionally, we compared the results of our monitored club, HK Brezno, with two other clubs: HK Sportrend Žiar nad Hronom and HK Iskra Partizánske. For the comparison of training sessions, we selected four attributes: players' active time, decision-making element, number of shots, and number of passes. The observed players participated in five training sessions reflecting modern coaching methods and five sessions based on traditional coaching methods. The measured results indicate that modern coaching is significantly more effective in HK Brezno than the traditional style. Similarly, in the other two clubs, we concluded that the traditional approach is not effective for the needs of contemporary hockey, whereas the modern coaching style meets all the requirements of modern hockey.

POZNAČTE SI TERMÍN, VOĽBY DO EURÓPSKEHO PARLAMENTU BUDÚ 6. - 9. JÚNA 2024
Get PDFPôvod Európskeho parlamentu je v Spoločnom zhromaždení Európskeho spoločenstva uhlia a ocele (ESUO), ktoré sa stalo spoločným zhromaždením v tom čase existujúcich troch nadnárodných Európskych spoločenstiev. Zhromaždenie následne získalo názov Európsky parlament. Odvtedy táto inštitúcia, ktorej poslanci sú od roku 1979 volení priamo, prešla výraznými zmenami: zo zhromaždenia vymenovaných poslancov sa stal volený parlament uznávaný ako orgán určujúci politický program Európskej únie. Európsky parlament volia občania Európskej únie, aby reprezentoval ich záujmy
